About Flash Builder

Flash Builder versions

Flash Builder is available in two versions: Standard and Premium.

Flash Builder Standard Flash Builder Standard provides a full-featured IDE that allows you to create applications using the Flex framework and Flash API. Flash Builder Standard also includes MXML, ActionScript, and CSS editors, as well as debugging tools. Flash Builder Standard provides a library of interactive charts and graphs that enable you to create rich data dashboards, interactive data analysis, and data visualization components.

Flash Builder Premium In addition to the Standard version features, Flash Builder Premium includes memory and performance profiling and automated testing tools. Use the Network Monitor to view the data that flows between a client application and a data service. The FlexUnit test environment allows you to generate and edit repeatable tests.

The repeatable tests can be run from scripts or directly within Flash Builder or outside the Flash Builder environment.

The Command Line Build feature allows you to synchronize a developer’s individual build settings with a nightly build.

Flash Builder for PHP Standard Flash Builder for PHP Standard provides a full-featured PHP IDE that includes Flash

Builder Standard integrated with Zend Studio 8. You can build mobile, web, and desktop applications using PHP, Flex, and ActionScript.

Flash Builder configurations

Flash Builder provides a single downloadable installer with the following two configuration options:

Stand-alone configuration Installs Flash Builder as a stand-alone integrated development environment (IDE). The stand-alone configuration is created specifically for developing applications that use the Flex framework and

ActionScript 3.0. This configuration is ideal for new users and users who intend to develop applications using only the

Flex framework and ActionScript 3.0.

Plug-in configuration Configures Flash Builder to run as a plug-in within an existing Eclipse™ installation.

To run the plug-in configuration, you must have Eclipse 3.7 or Eclipse 4.2 installed as follows:

• On Windows, to run Flash Builder 32-bit plug-in configuration, install Eclipse 3.7/4.2 32-bit

• On Windows, to run Flash Builder 64-bit plug-in configuration, install Eclipse 3.7/4.2 64-bit

• On Mac, to run Flash Builder 64-bit configuration, install Eclipse 3.7/4.2 Cocoa 64-bit

The Flash Builder plug-in and stand-alone configurations provide the same functionality. If you aren't sure which configuration to use, follow these guidelines:

• If you already have Eclipse 3.7 or 4.2 installed, use the plug-in configuration to add Flash Builder features to your existing copy of Eclipse.

• If you don't have Eclipse installed and your primary focus is on developing Flex and ActionScript applications, use the Flash Builder stand-alone configuration. This configuration also allows you to install other Eclipse plug-ins to expand the scope of your development work in the future.

For detailed information about installing Flash Builder, see the Flash Builder 4.7 release notes .

Chapter 2: Getting Started With Flash

Builder

Flash Builder is an integrated development environment (IDE) for developing applications using the Flex framework and ActionScript 3.0. You can develop applications for deployment on Adobe Flash Player, desktop applications for deployment on Adobe AIR, and mobile applications for deployment on various mobile devices.

Note: The information required to use Flash Builder is contained in the Flash Builder documentation. If you are using other Eclipse plug-ins (such as CVS or Java) with Flash Builder, or you want to extend the Flash Builder plug-ins, see

Adobe Flash Builder Extensibility Reference .

The Flash Builder development environments consists of the following components:

Workbench The term workbench refers to the Flash Builder development environment that contains all the tools to develop applications. The workbench contains three primary elements: perspectives, editors, and views. You use all three in various combinations at various points in the application development process.

See “ Customize the workbench ” on page 232.

Note: For more information about some of the Eclipse workbench features, see the Eclipse Workbench User’s Guide at http://help.eclipse.org/help31/index.jsp

.

Perspective A perspective is a group of views and editors in the workbench. Flash Builder contains two perspectives:

The Flash Development perspective for developing applications, and the Flash Debug perspective for debugging applications. Flash Builder Premium also contains the Flash Profiling perspective.

If you use the Flash Builder plug-in configuration (see “ Flash Builder configurations ” on page 3), your workbench can

contain additional perspectives such as a Java perspective that contains editors and views used to develop Java applications.

See “ Flash Builder perspectives and views ” on page 5.

Editor An editor lets you edit various file types. The editors available to you depend on the number and type of Eclipse plug-ins installed. Flash Builder contains editors for writing MXML, ActionScript 3.0, and Cascading Style Sheets

Views A view typically supports an editor. For example, when editing an ActionScript or MXML file, the supported views are displayed.

See “ Work with views ” on page 10.

Note: The term “view” is synonymous with the term “panel” as it is used in earlier versions of Flash Builder, Adobe

Dreamweaver®, and other Adobe development tools.

Workspace Not to be confused with workbench, a workspace is a defined area of the file system that contains the resources (files and folders) that make up your application projects. You can work with only one workspace at a time; however, you can select a different workspace each time you start Flash Builder.

See “ Move a project from one workspace to another

” on page 73 and “ Switch the workspace ” on page 74.

Resource The term resource is used generically to refer to the files and folders within the projects in a workspace.

USING FLASH BUILDER

Getting Started With Flash Builder

Project All of the resources that make up your applications are contained within projects. You cannot build an application in Flash Builder without first creating a project. Flash Builder supports various types of projects, depending on the type of application you are building.

See “ Types of projects ” on page 55 and “ Using Projects in Flash Builder ” on page 55.

Launch configuration A launch configuration is created for each of your projects, and it defines project settings that are used when running and debugging your applications. For example, the names and locations of the compiled application SWF files are contained in the launch configuration, and you can modify these settings.

See “ Manage launch configurations ” on page 96.

Flash Builder perspectives and views

To support a particular task or group of tasks, editors and supporting views are combined into a perspective. When you open a file that is associated with a particular perspective, Flash Builder automatically opens that perspective.

The stand-alone configuration of Flash Builder contains three perspectives:

• Flash Development

See “ The Flash Development perspective ” on page 5.

• Flash Debugging

See “ The Flash Debug perspective ” on page 110.

• Flash Profiling

See “ The Flash Profiling perspective and profiler views ” on page 122.

Note: The Flash Profiling perspective is available with Flash Builder Premium.

The Flash Development perspective

The Flash Development perspective includes the editors and views you require to create applications for the Flex framework. When you create a project, Flash Builder switches into the Development perspective so you can begin developing your application.

The focal point of the perspective (and the workbench generally) is the editor area. The editor area contains all of the currently open documents in a multitab interface.

When you create a Flex project, the main MXML application file is opened in the editor area. You can then open and switch between any of the MXML, ActionScript, and CSS documents you are working in. For more information, see

“ Flash Builder editors ” on page 11.

The Development perspective contains the editors and the following supporting views:

Package Explorer view

The Package Explorer view contains all of the projects and resources in the workspace and is therefore an essential element of the Flash Builder workbench. It is always displayed in the Development and Debug perspectives.

When you work in the Package Explorer, you can select a resource and view its properties.

Outline view

The Outline view presents a hierarchical view of the code structure of the selected MXML or ActionScript document so that you can inspect and navigate the sections or lines of code in the document. The Outline view also displays syntax error alerts that the compiler generates. This view is also available when you use the ActionScript editor.

Problems view

As you enter code, the Flash Builder compiler detects syntax and other compilation errors, and these errors are displayed in the Problems view. The Package Explorer marks nodes that contain errors.

When you debug your applications, errors, warnings, and other information are displayed in the Problems view. Each error or warning contains a message, the file and folder in which it is located, and its line number in the file. Problems remain in the Problems view until you correct them or they are otherwise resolved.

Create and work with fast views

Fast views are hidden views that you can quickly open and close. They work like other views, but do not take up space in the workbench while you work.

Whenever you click the fast view icon in the shortcut bar, the view opens. Whenever you click anywhere outside the fast view (or click Minimize in the fast view toolbar), the view becomes hidden again.

Note: If you convert the Package Explorer view to a fast view, and then open a file from the Package Explorer fast view, the fast view automatically is hidden to allow you to work with that file.

To create a fast view, do the following:

❖ Drag the view you want to turn into a fast view to the shortcut bar located in the lower-left corner of the workbench window.

The icon for the view that you dragged appears on the shortcut bar. You can open the view by clicking its icon on the shortcut bar. As soon as you click outside the view, the view is hidden again.

Flash Builder editors

When you develop applications in Flash Builder, you use the MXML, ActionScript 3.0, and CSS editors.

Editors are associated with resource types, and as you open resources in the workbench, the appropriate editor is opened. Each editor provides the functionality required to author the given resource type.

MXML editor You use the MXML editor to edit MXML code and to embed ActionScript and CSS code in

<fx:Script> and <fx:Style> tags.

ActionScript editor You use the ActionScript editor to edit ActionScript class and interface files. You can embed

ActionScript functions into an MXML file by using the <fx:Script> tag. However, it is a common practice to define classes in separate ActionScript files and then import the classes into MXML files. Using this method, you can define most of your applications in ActionScript.

CSS editor You use the CSS editor to display and edit Cascading Style Sheets. You can then apply styles to the visual elements of your applications. For more information, see Styles and themes.

Flash Builder Tips and Tricks

Using the MXML editor

When using the MXML editor, Content Assist helps you add standard Flex containers and controls to your user interface.

The following example shows how to use Content Assist to insert an <s:VGroup> container into an <s:HGroup> container. Because HGroup is a Spark component, Content Assist recommends a VGroup container, and not

<mx:VBox> .

1 Open an MXML file in the MXML editor.

The MXML file can be the main application file (a file with an Application container) or a custom MXML component file.

2 Place the insertion point in the parent container tag.

Last updated 12/3/2012

USING FLASH BUILDER

Getting Started With Flash Builder

For example, to insert a VGroup container inside an HGroup parent container, place the insertion point after the opening <s:HGroup> tag:

<s:HGroup>

insertion point here

</s:HGroup>

3 Type the component tag.

As you type the tag, Content Assist appears suggesting possible entries. Recommended components are listed in the normal black type color. Components that are not recommended appear gray.

In this example, VGroup is recommended and VBox is not recommended.

4 If necessary, use the arrow keys to select your tag from the menu, then press Enter.

12

In addition to the standard components, Content Assist lists custom components you defined in separate MXML and ActionScript files and saved in the current project or in the source path of the current project.

Content Assist can also suggest properties, events, effects, and styles. Press Control+Space to cycle through the recommendations in Content Assist.

You can change the type and order of recommendations for Content Assist. From the Preferences dialog, select

Flash Builder > Advanced.

Chapter 3: Code Development Tools in

Flash Builder

You edit MXML, ActionScript, and CSS code in Adobe® Flash® Builder™ with separate editors. The Flash Builder workbench is both project- and document-centric. The appropriate editor opens automatically because the editors are associated with resource types. The Flash Builder editors share capabilities, including code hinting, navigation, formatting, refactoring, and other productivity-enhancing features.

Content Assist, Quick Assist, and Quick Fix

Content Assist

As you enter MXML, ActionScript, and CSS code, hints and ASDoc reference documentation displays to help you complete your code. This feature is called Content Assist.

In the MXML editor, if you type within an MXML component, you are prompted with a list of all properties of that component. The following example shows code hints for properties of an MXML component:

Last updated 12/3/2012

USING FLASH BUILDER

Code Development Tools in Flash Builder

Selecting and entering properties displays possible property values (if predefined values exist). The following example shows code hints for property values:

15

Content Assist works similarly for the ActionScript editor and CSS editor.

Content Assist in the MXML editor

In the MXML editor, code hints appear automatically as you enter your code. The following example shows the code hints that are displayed when you add a tag to a Panel tag. It also shows the ASDoc reference documentation. Click inside the ASDoc content, or press F2 to display the content in a separate, scrollable window. Click outside the ASDoc window to close it.

Content Assist categorizes code hints by type, showing you both visual and nonvisual MXML components, properties, events, and styles.

By default, Content Assist only displays code hints for recommended types. Recommended types are those components available in the declared namespace or are otherwise available, depending on the enclosing tags. The components that are available to you in an application depend on the namespace declaration of the application and also the tags enclosing the insertion point in the editor.

For example, in some contexts only Spark components are allowed. In other contexts, both Spark and Halo components are allowed. Content Assist filters the code hints, depending on the context.

Press Control+Space multiple times to cycle through filters for displayed code hints, as listed below:

• Initial display: Recommended types

• All components

• Properties

• Events

Use Quick Assist to rename code elements that have the Rename/Refactor action enabled. That is, variables, methods, class names, parameters, imports, and states and ActionScript code inside MXML tags.

To rename all instances of a variable or method in your file, place your cursor in the selected variable or method name, and invoke Quick Assist. Then, select the Rename In File option to rename the variable or method name. Similarly, you can change the ID property of an MXML component.

Rename in Workspace

Use Quick Assist to rename code elements that have the Rename/Refactor action enabled across files in your workspace.

To rename all instances of a variable or method in your workspace, place your cursor in the selected variable or method name, and invoke Quick Assist. Then, select the Rename In Workspace option to rename the variable or method name.

You can update all references to the variable or method in your workspace.

Organize Imports

Place the cursor on any import statement, and invoke Quick Assist. Then, select the option to organize imports. For

more information on organizing import statements, see “ Organize import statements ” on page 34.

Generate Import Statement

If you have an undefined variable, you can place your cursor anywhere within the line of code and invoke Quick Assist.

You get an option to import the component. If the component has MX and Spark equivalents, both the options appear.

For example, if you have an undefined variable btn in your code: var btn:Button;

Place your cursor anywhere in the line of code, and press Control +1. You get options to import the Button component. If you select the Spark Button component, the import statement is created as follows: import spark.components.Button;

Split Variable Declaration

Use Quick Assist to split a variable into two parts: variable declaration and variable initialization.

Quick Assist appears in the following contexts.

18

Last updated 12/3/2012

USING FLASH BUILDER

Code Development Tools in Flash Builder

Context

Local variables inside a function

Multiple variables inside a function

Example

If you have a function, as follows: public function TestAS()

{ var i:int=10;

}

To split the variable using Quick Assist, place your cursor anywhere within the variable declaration var i:int=10; and press Control+1. Then, select the option to split the variable declaration.

The variable is split as follows: public function TestAS()

{ var i:int; i=10 ;

}

If you have a function as follows: public function TestAS()

{ var i:int=10, j:int=20;

}

To split the variables using Quick Assist, place your cursor anywhere within the variable declaration var i:int=10, j:int=20; and press Control+1. Then, select the option to split the variable declaration.

You can split the variable as follows: public function TestAS()

{ var i:int, j:int=20; i=10;

}

You can further split the variable j:int=20; by placing your cursor anywhere within the variable declaration, and press Control+1. Then, select the option to split the variable declaration.

The variable is split as follows: public function TestAS()

{ var i:int, j:int; j=20; i=10;

}

Assign to Variable

When you evaluate an ActionScript expression, if the expression returns a value, you can use Quick Assist to create a variable for that expression. Quick Assist is not available for methods that do not have a return type or if the return type is void .

The name of the variable that is created is derived from the name of the function or identifier in the expression. If the derived name exists, then the name is incremented.

For example, if you have the following code: var i:int; i;

Place your cursor after "i" , and invoke Quick Assist. Then, select Assign Statement To A New Local Variable. A variable "i2" is created. Because the variable i is already present, the new variable name is incremented to "i2" as follows:

19

Last updated 12/3/2012

USING FLASH BUILDER

Code Development Tools in Flash Builder var i:int; var i2:int = i;

For example, Assign to Variable appears in the following contexts:

Context

Literal Expression

Method Call

Property Access

Example

Quick Assist supports a wide range of simple and complex expressions.

For example, if you have an expression as follows:

100+150

Place your cursor anywhere within the expression, and press Control+1, then you get code like the following: var number2:Number = 110 + 500;

If you have the following code within a method: var ac:ArrayCollection = new ArrayCollection(); ac.createCursor();

Place your cursor within ac.createCursor(); and press Control+1. Then, select the option to assign the statement to a new local variable. The local variable is created as follows: var createCursor:IViewCursor = ac.createCursor();

If you have the following code within a property: var ac:ArrayCollection = new ArrayCollection(); ac.source;

Place your cursor anywhere within ac.source

, and press Control +1. Then, select the option to assign the statement to a new local variable. The local variable is created as follows: var source:Array = ac.source;

Convert Local Variable to Field

When you have local variables inside a function, Quick Assist lets you create a field in the class.

For example, if you have a variable inside a function, as follows: var i:int = 10;

Place your cursor anywhere within the variable definition, and invoke Quick Assist. Then, select Convert Local

Variable To Field. The class field is created as follows: private var i:int;

The name of the new field is the same name as the local variable, provided there are no conflicts in the class scope. If the name exists, then the field name is incremented, and you can rename the variable or method in your file.

Convert Local Variable to Parameter

When you have a local variable inside a function, Quick Assist lets you convert the local variable into a parameter.

For example, if you have a variable inside a function, as follows: public function method():void { var i:int = 10;

}

Place your cursor anywhere within the variable definition, and invoke Quick Assist. Select Convert Local Variable To

Parameter. The parameter is created as follows:

20

Last updated 12/3/2012

USING FLASH BUILDER

Code Development Tools in Flash Builder public function method(i:int):void { i = 10;

}

After the parameter is generated, you can rename all references of the parameter using linked mode.

Convert Anonymous Function to Named Function

When you have an anonymous function, you can quickly convert it to a named function using Quick Assist.

For example, if you have an anonymous function, as follows: public function method1():void;

{ var foo:Function = function(x:int, y:int, z:int):void;

{ trace(x, y, z);

}

}

Place your cursor within function() , and press Control+1. Then, select Convert Anonymous To Named Function.

The named function is created as follows: public function method1():void;

{ var foo:Function = fooFunction;

} protected function fooFunction(x:int, y:int, z:int):void;

{ trace(x, y, z);

}

After the function is generated, you can rename all references of the function using linked mode.

Assign Parameter to New or Existing Variable

When you have a function containing a parameter, Quick Assist lets you assign the parameter to a new instance variable.

For example, if you have a function containing a parameter, arg , as follows: class A{ function method(arg:String):void {

}

}

Place your cursor within arg , and invoke Quick Assist. Then, select Assign Parameter To New Instance Variable. The statement is changed to: class A { private var arg:String; function method(arg:String):void { this.arg = arg;

}

}

If you have instance variables already defined, you can assign the parameter to one of them.

For example, if you have a variable, myArg, defined as:

21

Last updated 12/3/2012

USING FLASH BUILDER

Code Development Tools in Flash Builder class A { private var myArg:String; function method(arg:String):void {

}

}

Place your cursor within arg , and invoke Quick Assist. Quick Assist detects the myArg variable, and shows the option

Assign Parameter To Instance Variable 'myArg'. Selecting this option, changes the statement to: class A { private var myArg:String; function method(arg:String):void { myArg = arg;

}

}

After the variable is generated, you can rename all references of the variable using linked mode.

Create New Local Variable With Cast Type

Quick Assist lets you quickly create a cast type local variable within a conditional expression.

For example, if you have an if statement: if(myObject is Button) {

}

Or a while statement: while(myObject is Button) {

}

Place your cursor within the if or why statement, and invoke Quick Assist. Quick Assist shows you the option Create

New Local Variable With Cast Type. Selecting this option generates the following conditional expression: if(myObject is Button) { var button:Button = myObject as Button;

}

After the local variable is generated, you can rename all references of the variable using linked mode.

Replace Conditional Statement With If-Else Statement

Quick Assist lets you replace a conditional statement with an if-else statement.

For example, if you have a conditional statement, as follows: var foo:String = bool?"Yes":"No";

Place your cursor anywhere within the condition statement, bool?"Yes":"No" , and invoke Quick Assist. Then, select

Replace Conditional With 'If-Else'. The if-else statement is generated, as follows: var foo:String; if (bool)

{ foo = "Yes";

} else

{ foo = "No";

}

Add Else, Else-If, Finally, and Catch statements

If you have an If statement, you can use Quick Assist to add Else and Else-If statements.

For example, when you have an if statement: var foo:Boolean = false; if(foo) {

}

Place your cursor within if , and invoke Quick Assist. Quick Assist shows you options to add else and else-if statements. If you’ve defined an else statement already, then Quick Assist shows you an option to add an else-if statement.

Similarly, if you’ve defined a try statement, you can add finally and catch statements.

Generate Getter/Setter

Quick Assist lets you generate getters and setters (get and set accessor functions) for class variables.

For example, if you have code like the following: private var result:ResultEvent;

Place your cursor in the variable, result , and invoke Quick Assist. Then, select the option to create the getter and setter for result. The Generate Getter/Setter dialog box appears. Using this dialog box, you can specify a new getter and

setter function. For more information on generating getter and setters, see “ Generate get and set accessor functions ” on page 53.

Generate functions

Quick Assist lets you generate special functions such as labelFunction, iconFunction, and such.

For example, to create a labelFunction for the following code:

<mx:DataGrid labelFunction="lblfunc" dataTipFunction="tipFunc" />

Place your cursor within "lblfunc" , and invoke Quick Assist. Then, select the option to create the labelFunction. Stub code for the function is generated as follows: protected function lblfunc(item:Object, column:DataGridColumn):String

{

// TODO Auto-generated method stub

}

Generate event handlers from MXML code

Quick Assist lets you generate event handlers with custom handler names within MXML code.

For example, to generate an event handler on clicking an <mx:Button> tag, enter the following code:

<mx:Button click="clickHandler" />

Then, place your cursor within "clickHandler" , invoke Quick Assist, and select generate event handler. The event handler and stub code are generated as follows:

<mx:Button click="clickHandler(event)" /> protected function clickHandler(event:MouseEvent):void

{

// TODO Auto-generated method stub

}

To customize the predefined stub code that Flash Builder generates, see “ Code templates ” on page 38.

Quick Fix

The Quick Fix feature in Flash Builder identifies unresolved issues in code and prompts you with a list of options to fix your code. The Quick Fix feature is supported only for ActionScript files or ActionScript code in an MXML file.

For example, when you have code as follows: import flash.display.Sprite; public class QuickFix extends Sprite

{ public function QuickFix()

{ var t:TestUnitClass

}

}

Flash Builder identifies the undefined variable by an error indicator with a bulb next to the error icon . When you hover your pointer over the undefined variable, you see the following Quick Fix options:

24

To use the Quick Fix feature, do any of the following:

• Select Quick Fix/Assist from the context menu in the editor, and select the required option.

• Use the keyboard shortcut Control+1(Windows) or Command+1 (Mac

Format, navigate, and organize code

The Flash Builder editors provide many shortcuts for navigating your code, including folding and unfolding code blocks, opening the source of code definitions, and browsing and opening types. Code navigation includes the ability to select a code element (a reference to a custom component in an MXML application file, for example) and go to the source of the code definition, wherever it is located in the project, workspace, or path.

Multiple line code blocks can be collapsed and expanded to help you navigate, view, and manage complex code documents. In Flash Builder, expanding and collapsing multiple-line code statements is referred to as code folding and unfolding.

Code formatting, indenting, and commenting

As you write code, Flash Builder automatically indents lines of code to improve readability, adds distinguishing color to code elements, and provides many commands for quickly formatting your code as you enter it (adding a block comment, for example).

To change the default formatting, in the Preferences dialog box, select Flash Builder > Formatting. You can change the order and grouping of the attributes.

When you paste MXML or ActionScript code into the code editor, Flash Builder automatically indents the code according to your preferences. You can also specify indenting for a selected block of code.

To specify the indentation preferences, in the Preferences dialog, select Flash Builder > Editors. You can specify the indent type and size.

Set, fold, and unfold code blocks

1 In the editor, click the fold symbol (-) or the unfold symbol (+) in the editor’s left margin.

25

Folding a code block hides all but the first line of code.

Unfolding the code block to make it visible again. Hold the mouse over the unfold (+) symbol to show the entire code block in a tool tip.

2 By default, code folding is turned on in Flash Builder. To turn off code folding, open the Preferences dialog and select Flash Builder > Editors, and then deselect the Enable Code Folding option.

Use the Outline view

The Outline view is part of the Flash Development perspective (see “ The Flash Development perspective ” on page 5),

and, therefore, is available when you edit code. You use the Outline view to more easily inspect and navigate the structure of your MXML, ActionScript, and CSS documents.

The Outline view contains three modes: Class, MXML, and CSS. In Class mode, the Outline view displays the structure of your code (classes, member variables, functions, and so on). In MXML mode, the Outline view displays the MXML structure (tags, components, controls, and so on). In CSS mode, CSS selectors and nested properties within them are displayed.

Selecting an item in the Outline view locates and highlights it in the editor, which makes it much easier to navigate your code.

Outline view in Class mode

When you edit an ActionScript document (or ActionScript contained in an MXML document), the Outline view displays the structure of your code. This includes import statements, packages, classes, interfaces, variables not contained in functions, and functions. This view does not include metadata, comments, namespace declarations, and the content of functions.

28

In the Outline view, nodes and items in the tree structure represent both the different types of language elements and their visibility. For example, red icons indicate private elements, green indicates public elements, and yellow indicates that the element is not private or public.

Outline view toolbar in Class mode

In Class mode, the Outline view toolbar contains the sort and filter commands, as the following example shows:

Outline view in MXML mode

When you edit an MXML document, which can contain both MXML and ActionScript code, both the Class and

MXML modes are available in the Outline view.

In MXML mode, each item in the Outline view represents an MXML tag and the following types of tags are displayed: components, controls, nonvisual tags such as WebService or State , component properties that are expressed as child tags (for example, layout constraints), and compiler tags such as Model , Array , and Script .

Use markers

Markers are shortcuts to lines of code in a document, to a document itself, or to a folder. Markers represent tasks, bookmarks, and problems and they are displayed and managed. Selecting markers opens the associated document in the editor and, optionally, highlights the specific line of code.

With Flash Builder, you must save a file to update problem markers. Only files that are referenced by your application are checked. The syntax in an isolated class that is not used anywhere in your code is not checked.

The workbench generates the following task and problem markers automatically. You can manually add tasks and bookmarks.

Tasks Task markers represent a work item. Work items are generated automatically by the workbench. You can add a task manually to a specific line of code in a document or to the document itself. For example, to remind yourself to define a component property, you might create a task called “Define skinning properties.” You can also add general tasks that do not apply directly to resources (for example, “Create a custom component for the employee log-in

prompt”). You use the Task view to manage all the task markers. For more information, see “ Add tasks ” on page 32.

Problems Problem markers are generated by the compiler and indicate invalid states of various sorts. For example, syntax errors and warnings generated by the compiler are displayed as problem markers in the Problem view. For more

information, see “ Filter the Tasks and Problems views ” on page 11.

Bookmarks You can manually add bookmarks to a line of code or a resource (folder or document). You use bookmarks as a convenience, to keep track of, and easily navigate to items in your projects. You use the Bookmarks

view to manage all bookmarks. For more information, see “ Add and delete bookmarks ” on page 33.

Note: The Tasks and Bookmarks views are not displayed by default in the Flash Development perspective. For more

information about adding these views, see “ Work with views ” on page

Navigate markers

Markers are descriptions of and links to items in project resources. Markers are generated automatically by the compiler to indicate problems in your code, or added manually to help you keep track of tasks or snippets of code.

Markers are displayed and managed in their associated views. You can easily locate markers in your project from the

Bookmarks, Problems, and Tasks views, and navigate to the location where the marker was set.

Go to a marker location

❖ Select a marker in the Bookmarks, Problems, or Tasks views.

Organize import statements

You can add, sort, and remove unused import statements in ActionScript and MXML script blocks using the Organize

Imports feature.

To use the Organize Imports feature, with an ActionScript or MXML document that contains import statements open in the editor, do one of the following:

• Select Organize Imports from the Source menu.

• Use the keyboard shortcut: Control+Shift+O (Windows) or Command+Shift+O (Mac

• Place the cursor on any import statement, and press Control+1. Then, select the option to organize imports.

Add missing import statements

If you have undefined variables within your ActionScript script or MXML script block, you can add all missing import statements all at once by using the Organize Imports feature.

Resolve ambiguous imports

When you use the Organize Imports feature in the MXML and ActionScript editors, the packages in which the classes are located are automatically imported into the document.

If you declare an ActionScript type that is present in two packages, you can choose the import statement for the required package. For example, Button is present in both spark.components

and mx.controls

packages.

If you have more than one instance of ambiguous import statements, all the unresolved imports are displayed letting you resolve them one after the other.

Remove unused import statements

Flash Builder places all import statements at the head of an ActionScript document or at the top of the script block of an MXML document by default.

To remove import statements that are not referenced in your document, keep the document that contains import statements open in the editor, and use the Organize Imports feature.

Sort import statements

You can quickly sort all the import statements in your ActionScript or MXML script block using the Organize Imports feature.

Flash Builder sorts the import statements alphabetically by default. To change the default order in which you want

Flash Builder to add the import statements, use the Preferences dialog. To do so, open the Preferences dialog, and select

Flash Builder> Editors > ActionScript Code > Organize Imports. For more information, see “ ActionScript code ” on page 237.

Auto-import missing import statements when copy-pasting ActionScript code

When you copy ActionScript code from an ActionScript document and paste into another ActionScript document, any missing import statements are automatically added. The missing import statements are added at either the package level or file level depending on where you paste the code.

Note: This feature is supported only for ActionScript code. If you copy ActionScript code from a file outside Flash Builder or from a file other than an ActionScript file, then the missing import statements are not added.

Consolidate import statements across MXML script blocks

If you have multiple MXML script blocks in a document with multiple import statements defined for each script block,

Flash Builder lets you consolidate all the import statements.

The Consolidate Import Statements Across MXML Script Blocks option in the Organize Imports preferences dialog box is selected by default. The import statements are consolidated, sorted, and added only once at the top of the first script block.

Consolidate import statements from the same package using wildcards

If you have multiple import statements from the same package, you can use wildcards in your import statement instead of repeating the statements multiple times.

You can specify the number of import statements that are allowed for types in the same package before the

<package>.* wildcard is used. For example, if you have multiple import statements from the flash.events

package,

Flash Builder consolidates all the import statements as: import flash.events.*;

By default, Flash Builder applies the <package>.* wildcard if you use more than 99 import statements from the same package. You can change the default value using the Organize Imports Preferences dialog. For more information, see

“ ActionScript code ” on page 237.

Code inspection, analysis, and fixing

Syntax error checking and highlighting

Flash Builder performs code analysis as you type ActionScript or MXML code and identifies coding syntax errors and all other errors by default.

Depending on the nature and severity of the errors, your application might not run properly until the errors are corrected.

Syntax error checking in Flex projects

When code syntax errors are encountered in a Flex project, you are notified in the following ways when you save your file:

• An error indicator is added next to the line of code, as the following example shows:

Flash Builder includes advanced search features that are more powerful than find and replace. To help you understand how functions, variables, or other identifiers are used, Flash Builder lets you find and mark references or declarations to identifiers in ActionScript and MXML files, projects, or workspaces. You can use refactor to rename the following identifiers in your code, and then update all references to them:

• Variables

• Functions

• Types (interface, class)

• Accessors (getter/setter)

• Attributes

• Metadata in MXML (effects, events, styles)

MXML, ActionScript, and CSS code templates

The ActionScript, CSS, and MXML code templates are context-based and can be called on pressing Control+Space.

You can use the pre-defined templates that are shipped with Flash Builder or you can create your own.

Insert code templates

To insert a code template in the code editor, type the name of the template in the code editor, and press Control+Space.

Last updated 12/3/2012

USING FLASH BUILDER

Code Development Tools in Flash Builder

For example, when writing ActionScript code, say, you use the for loop repeatedly. You can then define a code template for the for loop as follows: for (var i:int = 0; i < array.length; i++) { }

When you use a code template, you don’t have to type the complete code for the for loop. Instead, in the ActionScript class, type ' for ' and press Control+Space. A template option to create the for loop appears. On selecting the code template, the code that you defined in the template is inserted.

Templates can also contain template variables. A template variable is defined within ${} . The variable is resolved based on the corresponding variable definition in the editor.

For example, if you define a code template for the for loop as follows: for (var ${index}:int = 0; ${index} < ${array}.length; ${index}++) { ${cursor} }

And you invoke the code template after defining a variable myArr as follows:

{ var myArr:ArrayCollection = null;

}

Then, ${array} in the code template resolves to myArr , and the resulting code looks like:

{ var myArr:ArrayCollection = null; for (var ${index}:int = 0; ${index} < myArr.length; ${index}++) { ${cursor} }

}

Create and edit code templates

1 Open the Preferences dialog box, and select Flash Builder > Editors > Code Templates.

2 Code templates are categorized as ActionScript, MXML, and CSS code templates. Under each category, you find a set of predefined code templates. You can edit an existing template or add a new one.

3 To add a new template, select the code template category, and click Add. In the New Template dialog box, enter a name and brief description for the code template. Then, specify a context in which the code template must be called.

You can specify contexts for ActionScript and MXML code templates.

You can select from the following ActionScript contexts:

• ActionScript: Inserts the code template anywhere in the ActionScript document

• ActionScript statement: Inserts the code template within functions and within elements of a class

• ActionScript members: Inserts the code template only within elements of a class

• ActionScript Package Scope: Inserts the code template within a package, as follows:

Package

{

/* insert code template*/

}

You can select from the following MXML contexts:

• MXML: Inserts the code template anywhere in the MXML document

• MX Component: Inserts the code template within MX components available for Flex 3 SDK

• Spark Components: Inserts the code template within Spark components available for Flex 4 SDK or a higher

SDK version

On generating a click event for a button component, an event handler of type MouseEvent is generated as follows: button1_clickHandler(event:MouseEvent)

Specifies the modifiers for the generated function. static

Resolves to the event handler name. For a click event for the Button component, the event handler name can be button1_clickHandler

Defines the namespace value for the generated function.

The namespace value can be any of the following:

• protected

• public

• private

The default value is protected .

Example using code variables for event handler functions:

${namespace} ${modifiers}function

${:method_name('${component_id}_${event_name}Handler')}

${event}:${event_type}):${return_type}

{

// TODO Auto-generated method stub

${cursor}

}

Description

Specifies the metadata tags that are generated

Example

Generating get and set accessor functions for a

Bindable variable

Specifies the ASDoc that are generated for get and set accessor functions

Resolves to the variable type.

If the variable type is not specified, the generated get accessor function does not have a return type.

${metadata}

${asdoc}${namespace}

${modifiers}function get

${method_name}()${return_type}

{ return ${property};

}

${metadata}

${asdoc}${namespace}

${modifiers}function get

${method_name}()${return_type}

{ return ${property};

}

Resolves to the property name in the getter/setter dialog.

For a variable var i:int , i resolves to _i

Resolves to the data type of the generated set function.

Example using code variables for get and set accessor functions:

${asdoc}

${namespace} ${modifiers}function set ${method_name}(value${argument_type}):void

{ if( ${property} !== value)

{

${property} = value; dispatchEvent(new Event("${event_name}"));

}

}

Code variables for functions in an undefined class

Variable Description

${params} For an undefined function that accepts a specified number of arguments, the generated function has the same number of arguments with the type.

Example

Override or implement methods

Flash Builder provides you with an option to select and override parent class methods or implement interface methods.

1 Open the Override/Implement Methods dialog box by selecting Override/Implement Methods from the Source

ActionScript editor.

2 The methods for each parent class are displayed in a tree structure format. For each class, you can select the methods that you want to override and the methods that you want to implement.

3 You can select the insertion point to insert the selected methods. The default insertion point option depends on where you place your cursor in the editor while opening the Override/Implement Methods dialog box. The variable or method closest to the cursor location appears as an insertion point option.

Flash Builder generates the stub code for the selected methods.

Metadata code completion

Flash Builder displays code completion hints for metadata that you use in your MXML and ActionScript documents.

In an MXML document, metadata code hints are displayed within embedded <fx:Metadata> and <fx:Script> tags.

In an ActionScript document, metadata code hints are also displayed for ActionScript language elements like class names, variables, getters, and setters.

The code hints are contextual to the MXML and ActionScript document, and the code in which the metadata is used.

For example, when you invoke Content Assist within two blank lines of an ActionScript statement, code hints applicable to only that ActionScript statement appear. To see all the valid code hints applicable to the ActionScript or

MXML document, press Control+Space multiple times to cycle through the available code hints.

Use metadata code completion in MXML documents

In an MXML document or class, you can use metadata code completion in the following ways:

• Enter ’[’ within <fx:Metadata> tags, as follows:

<fx:Metadata>

[

</fx:Metadata>

• Enter ’[’ within <fx:Script> tags, as follows:

<fx:Script>

<![CDATA[

[

]]>

</fx:Script>

Use metadata code completion in ActionScript documents

In an ActionScript document, you can use metadata code completion when you enter ’[’ before a class name, variable, getter, or setter, as follows:

[ class GetSet

{

[ private var privateProperty:String;

[ public function get publicAccess():String

{ return privateProperty;

}

[ public function set publicAccess(setValue:String):void

{ privateProperty = setValue;

}

}

Code completion for custom metadata tags

Flash Builder supports code completion for custom metadata tags that are introduced on using third-party Flex frameworks.

Last updated 12/3/2012

43

USING FLASH BUILDER

Code Development Tools in Flash Builder

To enable code hints for custom metadata tags in your project, you generate a SWC file containing a metadata.xml

file, as follows:

1 Create a library project. The New Flex Library Project wizard guides you through the steps, prompting you for the

project name, location, and build path information. For more information, see “ Create Flex library projects ” on page 182.

2 Add the metadata.xml file in the src folder under the root folder of your library project. Include all the metadata tags that you want in the metadata.xml

file.

Add the metadata.properties

file (if any) in the appropriate locale folder. For example, locale/en_US or locale/ja_JP.

For more information about metadata tags, see About metadata tags in the Flex documentation.

3 Include the metadata.xml

file in the library SWC file, as follows: a Select Project > Properties > Flex Library Build Path.

The metadata.xml

file that you added appears in the Assets tab.

b Select the metadata.xml

file to include in the SWC file, and click OK.

The SWC file is compiled and generated in the output (bin) folder of the library project.

4 Select the locale folder to which you added the metadata.properties

file (if any).

5 After generating the SWC file, add it to the build path of your project, as follows:

1 Select Project > Properties > Flex Build Path.

2 Click Add SWC.

3 Enter or browse to the location of the SWC file, and click OK.

Once you add the SWC file to your build path, metadata code completion hints appear for the metadata tags defined in the metadata.xml

file. You can share the SWC file between your applications or distribute to other developers.

Customize file templates

Flash Builder allows you to customize the default information contained in new MXML, ActionScript, and CSS files.

Examples of information you can specify include variables for specifying author and date, variables for opening and closing tags and attributes, variables for various ActionScript declarations, namespace prefixes, and just about any content you want to include in a template file. File templates are especially useful for specifying introductory comments and copyright information.

The content of a new file is specified in a file template available from Preferences > Flash Builder > File Templates.

Templates are available for the following types of files:

Generate from usage

Use Quick Assist to generate stub code for an undefined method, variable, or class in your code. The generated stub code can be used as a placeholder for the code that you want to implement later without rendering your code

incompatible. To customize the predefined stub code that Flash Builder generates, see “ Code templates ” on page 38.

Use Quick Assist to generate stub code in the relevant class or MXML script block by selecting any of the following actions:

Generate Method Creates a method

For example, if you have code as follows: private function genFunc():void

{ bar();

}

Place your cursor anywhere in the line of code containing bar(); and press Control+1. An option to create a function appears. On selecting this option, a new function is generated as follows: private function bar():void{}

You can also generate a function for an undefined function in a referenced class. For example, if you have an undefined function "setValue()" in the referenced class "MyClass", as follows:

MyClass cls = new MyClass(); cls.setValue(5);

51

Last updated 12/3/2012

USING FLASH BUILDER

Code Development Tools in Flash Builder

Place your cursor anywhere in the line of code containing "setValue" and press Control+1. An option to create a function appears. On selecting this option, a new function setValue(int) is generated in the referenced "MyClass" as follows:

private function setValue(param0:int):void

{

// TODO Auto Generated method stub

}

Generate Variable Creates a property

For example, if you have code, where, i is an undefined variable, as follows: public function MyClass

{ i;

}

Place your cursor anywhere in the line of code containing i; and press Control+1. You get options to create a local variable or a field.

Selecting the option to create a local variable, creates the variable as follows: var i:Object;

Selecting the option to create a field, creates a class-level variable as follows: private var i:Object;

You can also generate a property for an undefined variable in a referenced class. For example, if you have an undefined variable "aValue" in the referenced class "MyClass", as follows:

MyClass cls = new MyClass(); cls.aValue = "str";

Place your cursor anywhere in the line of code containing aValue , press Control+1, and select Create Field Variable.

A property aValue of type string is generated in the referenced "MyClass" as follows: private var aValue:String;

Generate Class/Interface Creates a class or interface

For example, if you have code, where Foo is undefined, as follows: public function myFunction():Foo;

{

}

Place your cursor anywhere in the line of code containing Foo; and press Control+1. Options to create a class or interface named Foo appear. Select one of these options to open either the New ActionScript Class wizard or New

ActionScript Interface wizard. Enter the necessary details and click Finish. After clicking Finish, a class or interface with the name Foo is created.

When you generate a new class, you can create an ActionScript class with a parametrized constructor.

For example, if you have code like the following:

Private function func(): void {

New NewClass("str1");

}

52

Last updated 12/3/2012

USING FLASH BUILDER

Code Development Tools in Flash Builder

Place your cursor anywhere in the line of code containing NewClass("str1"), press Control+1, and select Create Class.

An ActionScript class with a parametrized constructor is created. If you, however, specify a superclass for the

ActionScript class, then a parameterized constructor is not generated.

Adobe Community Professional, Paul Robertson, blogged about using Quick Assist for external classes and interfaces .

Generate Event Handler Generates event handler functions

For example, if you have code like the following: public function MyClass

{

Var button:Button = new Button(); button.addEventListener(DragEvent.DRAG,dragHandlerFunction);

}

Place your cursor anywhere in the line of code containing dragHandlerFunction , and press Control+1. Then, select the Quick Assist option to create the event handler. The event handler function is created as follows: protected function dragHandlerFunction (event:DragEvent):void

{

}

Generate Import Statement From Usage Creates an import statement

For example, if you have code where the variable type Button is undefined, as follows:

<fx:Script>

<![CDATA[ var btn:Button;

]]>

</fx:Script>

Place your cursor anywhere in the line of code containing var btn:Button , and press Control+1. You get an option to import Button if a class named Button is available in the project. The import statement is created as follows: import spark.components.Button;

You can generate import statements for function arguments, function return types, and such.

Generate get and set accessor functions

Get and set accessor functions (getters and setters) let you keep class properties private to the class. They allow users of the class to access those properties as if they were accessing a class variable (rather than calling a class method).

Flash Builder can generate ActionScript get and set accessor functions for class variables. You can select a bindable property and generate get and set accessor functions for that property. You can also specify a custom event name at the time of generating code.

How to generate get or set accessor functions

1 With an ActionScript file open in the Source Editor, place the cursor on a class variable.

2

3 In the Generate Getter/Setter dialog, specify details for the accessor functions and click OK.

Note: To view the code that is generated, select Preview before clicking OK.

To customize the predefined code that Flash Builder generates, see “ Code templates ” on page 38.

53

Last updated 12/3/2012

USING FLASH BUILDER

Code Development Tools in Flash Builder

When you generate getters and setters, Flash Builder provides the following options:

• Make the class variable private.

Typically, class variables have private access.

• Rename the class variable, suggesting a leading underscore for the variable name.

By convention, private class variables have a leading underscore.

• Rename the accessor functions.

• Specify a bindable property and a custom event name.

When you specify a bindable property, a [Bindable] tag is defined above the generated accessor function in the generated code.

• Specify whether to generate both getter and setter accessor functions.

• Specify the namespace value for the accessor function.

• Specify the placement of the accessor function in any of the following locations:

• Before the first method

• After the last method

• Before variable declarations

• Preview the code that is generated.

Chapter 4: Using Projects in Flash Builder

Adobe Flash Builder groups the resources (folders and files) that constitute an application into a container called a

project.

Use the Package Explorer view to add, edit, and delete project resources. You can also close projects within a workspace, import resources, and link to external resources.

Types of projects

Flash Builder supports the following various types of projects, depending on the type of application you are building.

Flex projects

Use a Flex Project wizard to build a web application or a desktop application that is based on the Flex framework. A web application runs in Adobe Flash Player, while a desktop application runs in Adobe AIR. When creating the project, you specify whether the project is for web or desktop applications.

A Flex project contains a set of properties that control how the application is built, where the built application resides, how debugging is handled, and the relationships to other projects in the workspace.

A Flex Project contains a default MXML application file. Other MXML files in the project can also be application files.

If you have an ActionScript file in your Flex project, you can set the ActionScript file as the default application by selecting Set As Default Application from the context menu for the project.

See “ Flex projects

” on page 57 and “ Develop Web and Desktop Applications in Flash Builder ” on page 155

Flex Mobile Projects

Use a Flex Mobile Project wizard to create an Adobe AIR application targeted for a Mobile Platform. The application is based on the Flex framework. You can use Flash Builder to preview, debug, and profile mobile applications from the desktop or on a device.

A Flex Mobile Project has a single default MXML application file. Typically, a mobile application has a set of View components that display content on a device. The default MXML application file launches the default View component.

Flash Builder uses the AIR Debug Launcher (ADL) to preview mobile applications on the desktop. Although not a true emulation, the ADL allows you to view the application layout and behavior, with options to rotate the application.

You can preview a mobile application on a device connected to the development computer’s USB port. When previewing on a device, Flash Builder exports the application to the device.

See “ Flex mobile projects ” on page 58 and

Developing mobile applications in Flash Builder .

Flex Library Projects

Use a Flex Library Project wizard to build custom code libraries that you share between applications or distribute to other developers. Typically, you use library projects to package and distribute components and resources to other developers.

A library project generates a SWC file, which is an archive file for Flex components and other resources.

Last updated 12/3/2012

USING FLASH BUILDER

Using Projects in Flash Builder

See “ Use Flex library projects ” on page 181.

ActionScript Projects

Use an ActionScript Project wizard to create web or desktop applications that are based on either the Flash APIs or

Adobe AIR APIs. When creating the project, you specify whether the project is for a web or a desktop application.

You work exclusively in the ActionScript editor, the debugging tools as necessary, and then build the project into SWF files to preview and test your application.

When you create an ActionScript project or a stand-alone ActionScript file to contain functions, a class, or interface, the Flex development perspective is modified to support the ActionScript editor. The primary supporting views of the

ActionScript editor are the Outline and Problems views.

See “ ActionScript projects ” on page 59.

ActionScript Mobile Projects

Use an ActionScript Mobile Project wizard to create mobile applications that are based on the Adobe AIR API. When creating the project you specify a target Mobile Platform and some mobile applications settings. You can use Flash

Builder to preview the mobile application from the desktop or on a device.

Flash Builder uses the Adobe AIR Debug Launcher (ADL) to preview, debug, and profile mobile applications on the desktop. Although not a true emulation, the ADL allows you to view the application layout and behavior, with options to rotate the application.

You can preview a mobile application on a device connected to the development computer’s USB port. When previewing on a device, Flash Builder exports the application to the device. You can use Flash Builder to debug the application exported to a device.

See “ Create ActionScript mobile projects ” on page 60.

ActionScript Library Projects

Use an ActionScript Project Library wizard to build ActionScript custom code libraries. Typically, you create the

ActionScript Library project, add specific ActionScript classes, and compile the project. Flash Builder then generates a SWC file that you can distribute to other developers or share between applications.

See “ Create ActionScript library projects ” on page 185.

Flash Professional Projects

Use a Flash Professional Project wizard to edit, build, or debug FLA or XFL files created in Adobe Flash Professional.

This feature allows Flash Professional developers to take advantage of the editing and debugging environment available with Flash Builder. Flash Professional projects are available in Flash Builder only if you have Flash

Professional installed.

See “ Using Flash Builder with Flash Professional ” on page 230.

Create projects in Flash Builder

Flash Builder lets you create different types of projects such as Flex, Flex on mobile, ActionScript, and Adobe AIR projects, as well as other types of projects. Flash Builder provides you a project-creation wizard that guides you through the steps, prompting you for the type of project to create, the project name, location, application type (web or desktop),

SDK versions, and other options.

The MX Only option is useful for creating applications that are similar in design to applications created with the previous release of Flex (that is, Flex 3), but still have access to the latest Flex and Flash Builder features (such as the states syntax, advanced CSS, compiler improvements, and other language features).

If you specify MX Only for a project, then Spark components are not available to applications in the project.

You can convert a Flex project to be an MX Only project. However, Flash Builder does not rewrite any code in the project. Manually update your code to remove any reference to Spark components.

Build paths, native extensions, and other project configuration options

When you create a Flex or ActionScript project, you can customize its configuration. All additional configuration steps are optional.

Note: You can also change a project’s configuration after the project has been created by selecting Project > Properties.

Source Path Use the Source tab to add additional source folders to a project. You can reorder the source folders, edit the location of folders, and remove folders from the source path.

Main source folder, main application file, output folder URL By default, Flash Builder places source files in a projects src folder.

For Flex projects, the default name of the main MXML application file is the name of the project. You can change these defaults when creating the project.

When you create a project, Flash Builder runs application files from a default URL based on your project settings.

Specify an output folder URL to override the default settings. The output folder URL is useful when you build and deploy your application on your project server, but you debug your application on a web server. You then specify the web server URL as the output folder URL. For example, if you specify http://myserver/test.swf as the output folder

URL, a launch configuration is created with that URL.

See “ Set up a project output folder

” on page 84 and “ Run and debug applications ” on page 95.

Library Path Use the Library Path tab to specify the framework linkage and build path libraries

• Component Set

The component set is available only for Flex projects. Typically, you make all components available. In some cases,

you specify MX components only. See “ Component Set (MX + Spark, Spark Only, or MX Only) ” on page 82.

• Framework Linkage

For Flex projects, application classes for Flex 4.5 or a higher version of the Flex framework use dynamic linking by

default. For more information, see “ Application Framework Linkage ” on page 83.

The following options are available only for Flex projects, and are enabled by default:

• Verify RSL Digests (Recommended For Production)

• Remove unused RSLs

Note: This option is not available for Flex frameworks older than Flex 4.5.

• Use Local Debug SWF RSL When Debugging

• Automatically Determine Library Order Based on Dependencies

• Build Path Libraries

You can add or remove project libraries, SWC library folders, or SWC files to the build path. You can also change the build path order.

Use the Edit button to change the location of added libraries or folders.

Use the Add Flex SDK button to restore the default SDK for a project if you removed the Flex SDK from the build path.

Native Extensions The Native Extensions tab is available only for mobile projects. Use the Native Extensions tab to include ActionScript Native Extension (ANE) files to provide native platform capabilities in your applications.

Important: You can create ActionScript extensions only for mobile projects that support Adobe AIR 3.0 or a higher version.

For more information, see “ Add native extensions to a project ” on page 203.

Project resources

Projects consist of resources (folders and files) that you can manage from the Package Explorer. Projects are contained within a workspace. The Package Explorer provides a logical representation of the workspace in the file system. The

Package Explorer is refreshed each time you add, delete, or modify a resource.

You can also edit project resources directly in the file system, bypassing Flash Builder and the Package Explorer.

Create or delete files and folders in a project

An application in Flex typically consists of an MXML application file, one or more views (mobile projects only), and one or more standard Flex components. You can also have one or more custom components defined in separate

MXML, ActionScript, or Flash component (SWC) files. By dividing the application into manageable chunks, you can write and test each component independently from the others. You can also reuse a component in the same application or in other applications, which increases efficiency.

You can use Flash Builder to build custom MXML and ActionScript components and then insert them into your

applications. For information on building ActionScript components, see “ Create an ActionScript class ” on page 65.

You can also build an MXML component directly using code.

Create files and folders in a project

3 Enter the filename and click Finish.

You can also add folders and files that are located outside the current project; for more information, see “ Link to resources outside the project workspace ” on page 69.

You can add folders to your project as needed. For example, you can create a folder to store all of your data models.

Or, you can organize all the assets that make up the visual design of your application.

2 If you have multiple projects in your workspace, select the project to add to the stand-alone folder.

If you create the folder in the source path folder, it is treated like a package name. You can then place source files inside that folder, which the compiler recognizes.

If you create the folder outside the source path folder, you can later make it the root of a package structure by adding it to your source path. After you complete this procedure, select Project > Properties and then select Flex Build Path.

Click Add Folder and navigate to the newly created folder.

3 Enter the folder name and click Finish.

Delete folders and files

Deleting folders and files from your project removes them from the workspace and, therefore, from the file system.

Note: If you delete a linked resource, you delete only the link from your project, not the resource itself (see “

2 Specify the basic properties of your new skinnable component, and then click Finish.

Flash Builder creates an ActionScript class that extends from the base component or the skinnable component. By default, the base component is spark.components.supportClasses.SkinnableComponent

. You can, however, change the base component to any other component that is a subclass of the skinnable component.

You can also add any ActionScript interfaces that the new skinnable component can implement. For more

information on creating ActionScript interfaces, see “ Create an ActionScript interface ” on page 65.

The SkinnableComponent is created in the selected location and package. A reference to the component is added automatically, by default, in the main MXML file.

Using ActionScript Workers

Flash Builder supports multi-thread ActionScript programing by letting you run an ActionScript program as a worker.

A worker runs in parallel to the main ActionScript program, and can communicate with the main ActionScript program and other ActionScript workers.

ActionScript workers let you create more responsive games and applications by offloading tasks and computations to the background workers. The workers run concurrently, making your game-play more responsive. To understand more about ActionScript workers, see Using workers for concurrency .

For a video on creating and using ActionScript workers, see this video by Adobe Evangelist Lee Brimelow.

Create an ActionScript worker

You can use a wizard in Flash Builder to create an ActionScript worker for your Flex and ActionScript projects by following these steps:

1 Select File > New > ActionScript Worker.

2 Specify a package name for your ActionScript worker. If you don't specify a package, the class is declared in the default package. If you specify a package folder that does not exist, the wizard creates it.

3 Name the ActionScript worker file.

4 An ActionScript worker extends from the flash.display.Sprite

class by default. So, you can select only those classes that extend from Sprite.

5 Add any interface that contains constants and methods that you want to use in your ActionScript worker.

6 Specify any of the following code generation options:

Generate Constructor from Superclass Generates a constructor with a super() call. If the superclass constructor takes arguments, the arguments are included in the generated constructor and passed up in the super() call.

Generate Functions Inherited from Interfaces Generates function stubs for each interface method. The stubs include a return statement that returns null (or 0 or false for primitive types) so that the stubs compile.

Generate Comments Inserts a " //TODO: implement function " in the generated functions or constructors.

Using Projects in Flash Builder

Flash Builder provides ActionScript worker code templates that let you quickly add code for a worker file. For more

information on using code templates, see “ Code templates ” on page 38.

To convert an existing ActionScript class into a worker, follow these steps:

1 In the Package Explorer, select the ActionScript class that you want to convert into an ActionScript worker.

2 From the Package Explorer context menu, select Set As ActionScript Worker.

Whenever you create an ActionScript worker, the worker file is added to the list of ActionScript workers in the Project

Properties dialog box.

Specify ActionScript worker usage

When you create an ActionScript worker, edit the worker, or convert an ActionScript class to a worker, you can specify the worker usage.

You can choose to embed the worker or load it externally by selecting one of the following options:

Embedded Worker Generates a SWF file for the ActionScript worker class that you want to embed. The SWF file is generated in the "workerswfs" folder of your project, instead of a user-selected output folder.

When you choose to embed a worker, Flash Builder generates a class named Workers.as. The generated class contains code to embed the SWF file and also create a getter method. You can use the getter method to access the ByteArray class of the embedded ActionScript worker.

Important: You should not modify the contents of automatically generated class.

For example, if you create an embedded ActionScript worker called “MyWorker”, code like the following is generated: public class Workers

{

[Embed(source="../workerswfs/MyWorker.swf", mimeType="application/octet-stream")] private static var MyWorker_ByteClass:Class; public static function get MyWorker():ByteArray

{ return new MyWorker_ByteClass();

}

}

Whenever you add, rename, move, or delete an ActionScript worker, Flash Builder modifies the generated code in the

Workers.as file.

If a file named Workers.as exists in the project, Flash Builder generates the class with these filenames in the specified order:

1 WorkersManager.as

2 WorkersHolder.as

If files with all these names exist, then Flash Builder generates the class with a unique filename by appending numbers to these filenames sequentially. For example, Workers1.as, WorkersManager1.as, WorkersHolder1.as, Workers2.as, and so on. You can choose to rename these files if you want; Flash Builder remembers and uses the new filename to generate code.

When you run or debug the project containing an embedded ActionScript worker, the "workerswfs" folder contains the debug SWF files. When you export a release build, the release SWF files overwrite the debug SWF files in the

"workerswfs" folder.

Externally Loaded Worker Generates the SWF file for the ActionScript worker class in a user-selected output folder.

Link to resources outside the project workspace

You can create links to resources outside the project and workspace location. You can link to folders and files anywhere on the file system. This option is useful when you have resources that are shared between your projects. For example, you can share a library of custom Flex components or ActionScript files among many different Flex projects.

Folders that contain linked resources are marked in the Package Explorer (as the following example shows), so that you can distinguish between normal and linked resources.

69

Other examples for linking resources include a folder of image file assets, or situations when the output folder is not in the project root folder.

When you work with shared resources, the changes you make to the source folders and files affect all of the projects that are linked to them. Be cautious when you delete linked resources from your projects. In some cases you merely

delete the link reference, and in others you delete the source itself. For more information, see “ Delete folders and files ” on page 64.

Note: A best practice is to link other projects to your Library Project. Linked resources are encouraged only for third-party libraries with a SWC file.

Folders that are added to the source path are marked in the Package Explorer.

Refresh resources in the workspace

As you edit, add, or delete a project’s resources, the workbench automatically refreshes the various views that display these resources. For example, when you delete a file from your project, that change is immediately reflected in the

Package Explorer.

You can also edit resources outside Flash Builder, directly in the file system. These changes are visible only inside Flash

Builder after you refresh the workspace.

By default, in the stand-alone configuration of Flash Builder, the workspace is refreshed automatically. This option is configurable in Flash Builder preferences. Open the Preferences dialog and select General > Workspace. You can also change the Flash Builder default behavior so that it never refreshes the workspace automatically.

Manually refresh the workspace

Projects in Package Explorer

All projects in a workspace are displayed in the Package Explorer, as the following example shows. The Package

Explorer provides a tree view of projects from both a physical view and logical (flat) view. Using this view, you manage your projects by adding and deleting resources (folders and files), importing and linking to external resources, and moving resources to other projects in the workspace.

72

Highlights of the Package Explorer include:

• Displaying ActionScript packages in either a hierarchical or flat presentation.

Use the Package Explorer’s menu to specify the package presentation.

• Flex project libraries and ActionScript libraries are represented in two top-level nodes.

Flex project libraries have one node for the Flex SDK and the other for referenced libraries. Similarly, ActionScript project libraries have one node for the AIR SDK and the other for referenced libraries.

You can expand a library’s contents and open editors to view attachments.

• Error and warning badges on Package Explorer nodes notify you of problems within a package.

• You can limit which projects and resources are visible.

You can create a working set (a collection of resources), create display filters, and sort resources by name and type.

These options are available from the Package Explorer menus. For more information about modifying views, see

“ Customize the workbench ” on page 232.

• You can expand ActionScript, MXML, and CSS files and see a tree view of their contents.

From the Package Explorer, you can open the project resources for editing. For example, you can edit MXML and

ActionScript in <fx:Script> blocks and CSS in <fx:Style> blocks. For more information about working with the

Flash Builder editors, see “ Flash Builder editors

” on page 11 and “ Build user interfaces ” on page 156.

Then you add projects, files, and folders, and organize and manage them as needed.

Most menu commands that you use in the Package Explorer view are also available from the view’s context menu.

Move a project from one workspace to another

You use a combination of deleting and importing operations to move a project from one workspace to another. When you delete a project from a workspace, you can remove it from the workspace but leave it in the file system. After you remove a project from one workspace, you can import it into another.

Specify an SDK for a project

Flex projects

When creating a Flex project, Flash Builder uses the default SDK that is available in your Flash Builder installation.

You can, however, specify to use a Flex SDK that is not available in your Flash Builder installation.

For example, if you want to compile your project using an Apache Flex SDK, follow these steps:

1 Download the Apache Flex SDK from www.adobe.com/go/apacheflex_flashbuilder .

2 Add the downloaded SDK to your Flash Builder installation by selecting Project > Properties > Flex Compiler, and clicking Configure Flex SDKs.

3 In the Project Properties dialog box, select Flex Compiler > Use a specific SDK, and select the SDK to use.

For more information about installing and using the Flex SDK, see “ Installed Flex SDKs ” on page 241.

ActionScript projects

ActionScript projects use the AIR SDK. For more information on the AIR SDK, see “ Installed AIR SDK ” on page 241.

Note: You cannot use a Flex SDK with an ActionScript project.

Delete a project

When you delete a project, you remove the project from the current workspace. You can also remove the project from the file system at the same time.

Instead of deleting the project from the workspace, you can close the project. Closing the project lets you keep a reference to it in your workspace and also free some system resources.

1 In the Package Explorer, select the project to delete.

2 Select Edit > Delete from the main menu.

3 Select an option:

Also Delete Contents Under Directory Permanently removes the project from the workspace and the file system.

Do Not Delete Contents Removes the project from the workspace but not from the file system.

Close and open projects

To save memory and improve build time without deleting a project, you can close it. When you close a project, you collapse the project and its resources, however, the name remains visible in the Package Explorer. A closed project requires less memory than an open project, and is excluded from builds. You can easily reopen the closed project.

1 In the Flex Package Explorer, select the project to close or reopen.

Switch the main application file

When you create a project, the main application file is generated for you. By default, it is named after the project. The main application file is the entry point into your applications and becomes the basis of the application SWF file.

However, as you add files to your application, you might want to designate a different file as the main application file.

If you prefer to set multiple files as application files so that each application file is built in to a separate SWF file, see

“ Manage project application files ” on page 74.

1 In the Package Explorer, select the MXML application file that you want to make the main application file.

2 From the Package Explorer context menu, select Set as Default Application.

You can manage the application files in your project by selecting Project > Properties > Flex Applications (or

ActionScript Applications if you’re working with an ActionScript project).

Manage project application files

Usually, a project has a single main application file, which serves as the entry point to your application. The Flash

Builder compiler uses this file to generate the application SWF file.

For example, you can have a complex application with many custom MXML components that represent distinct but interrelated application elements. You can create an application file that contains a custom component and then build, run, and test it separately.

By default, whenever you add an MXML application file to your Flex project, you can run the application, and it is added to the list of project application files. All files defined as application files must reside in your project’s source folder.

You can manage the list of application files by selecting a project and viewing its properties.

1 In the Package Explorer, select a project.

2 Select Project > Properties from the main menu or select Properties from the context menu.

3 In the Project Properties dialog box, select Flex Applications (or ActionScript Applications if you are working with an ActionScript project).

4 Add and remove application files as needed. Click OK.

Projects requiring special handling

Some Flex projects require special handling upon import and export. For example:

• The project references an earlier version of the Flex SDK

• The project references service files for access to server-side data

• The Zend Framework configuration for access to PHP services needs to be updated

• The project uses LiveCycle Data Services links to a data model file.

When exporting or importing a Flex project, some contents of the project require special handling.

• Different versions of the Flex SDK

You can import a Flex project that references a version of the Flex SDK that is not installed with your Flash Builder.

See “ Installed Flex SDKs ” on page 241 for information on downloading and installing additional versions of the

Flex SDK. If Flash Builder cannot find a specific version of the Flex SDK, browse to the location of the SDK.

• Service files

Flex server projects that connect to data services, such as ColdFusion or BlazeDS, contain a services folder whose

ActionScript class reference deployed server files. When exporting the project, Flash Builder exports the services folder but ensure that a server and the corresponding server-side files exist when importing. Upon import, you might have to manually deploy the server-side files and also update the server addresses in classes in the server-side files.For projects that connect to services using LiveCycle Data Services or BlazeDS, make sure that service destinations are available on the target server.

• Zend Framework

Flex projects that connect to data services using PHP and the Zend Framework contain two configuration files.

Upon import, examine these files to make sure that they are configured properly for your system: amf-config.ini

gateway.php

See Installing Zend Framework for information on installing, configuring, and troubleshooting your Zend Framework installation.

• Data model files (LiveCycle Data Services)

A Flex project that uses LiveCycle Data Services links to a data model file. Upon export and subsequent import,

Flash Builder references the actual data model file and not a link to it. If you want to use a linked file, and not the one packaged with the exported project, then change the data model file using project properties. Select Project >

Properties > Data Model and make the changes.

USING FLASH BUILDER

Using Projects in Flash Builder

Build projects

Adobe® Flash® Builder™ automatically builds and exports your projects into applications, creating application and library files, placing the output files in the proper location, and alerting you to any errors encountered during compilation.

There are several options for modifying the build settings to control how your projects are built in to applications. For example, you can set build preferences on individual projects or on all the projects in your workspace. You can also modify the build output path, change the build order, and so on. You can also create custom build instructions using third-party build tools such as the Apache Ant utility.

When your applications are ready to be released, you have the option of publishing all or selected parts of the application source code. Users can view your application source code in a web browser, similar to the way they are able to view HTML source code.

Understand how projects are built and exported

A typical workflow consists of building your Flex and ActionScript projects with the Build Automatically option enabled. During the development process, Flash Builder gives you errors and warnings in the Problems view. When you run your application, a debug version of the SWF file is placed in the project output (bin) folder along with required assets and an HTML wrapper. This build contains debug information and is suitable for developer use only.

For more information about exporting projects, see “ Export and import projects ” on page 74.

When your application is ready to deploy, you create an optimized, release-quality version of your application using the Export Release Build wizard. This stores the SWF file in the bin-release folder. Since debug information is removed, the file size is smaller. This version is a production build that end users can view. For Adobe AIR projects, AIR applications are exported to an AIR file. You use Export Release Build to create a digitally signed AIR file, which users must install before running an application (similar to an install.exe).

For library projects, you do not have to export. The SWC file built by a Flex library project is suitable for both developer

and production use. For more information, see “ Use Flex library projects ” on page 181.

Build basics

MXML and ActionScript 3.0 are compiled languages. Compiled languages are different from interpreted languages, such as JavaScript, that can be executed by their runtime environments. That is, MXML and ActionScript 3.0 must be converted into a compiled format before Flash Player can run them. This process, along with the generation of related output files, is called building.

Flash Builder automatically builds your projects whenever a file in your project is changed and saved. You also have the option of building your applications manually. Understanding the build process and the output files that are generated helps you to diagnose and repair project configuration problems, if any.

Flex projects Source files and embedded assets (such as images) are compiled into a single output SWF file. The SWF file can be run directly in the stand-alone Flash Player or in a web browser through an HTML wrapper file that is also generated by the build. These files are generated into the project’s output folder. The output folder is named bin, by default, but you can rename it.

ActionScript 3.0 projects Like Flex projects, ActionScript 3.0 projects compile source files and embedded assets into a

SWF file.

Flex library projects For library projects, source files are components and related resources. When library projects are built, a SWC file is generated into the output folder. A SWF file is archived into a SWC file containing components, resources, and a catalog.xml file that is the manifest of the elements contained within the SWF file.

USING FLASH BUILDER

Using Projects in Flash Builder

Automatic builds

In the stand-alone configuration of Flash Builder, the option to Build Automatically is selected, by default, and your applications are built automatically. In the plug-in configuration, select the Build Automatically option. Deselecting the Build Automatically option prevents the compiler from identifying syntax errors. The Problems view then does not display warning and error messages as you enter code. Only when you compile the project, the Problems view displays any warning and error messages. It is therefore recommended to set Flash Builder to build automatically.

Advanced project build options

With the advanced build options, you can control the timing and scope of your builds. For example, you can build a single project, all projects in the workspace, or create a working set (a collection) of projects to build. All build commands are accessible from the Project menu, as shown in the following example.

80

The Flash Builder compiler is incremental. It builds only those resources that have been added or affected by updates and ignores all others. This saves time and system resources. You have the option, however, to rebuild all the resources in the project. You do this by performing a clean build. You might do this if your application is behaving erratically during testing and you want to eliminate all potential sources of the problem by discarding and rebuilding all the files

in your project. For more information, see “ Advanced build options ” on page 85.

If you create dependencies between separate projects in the workspace, the compiler automatically determines the order in which the projects are built, so these dependencies resolve properly. You can, however, override the default build order and manually set the order in which the projects in your workspace are built.

You can also modify the build path, application list, and compiler settings for each project in the workspace.

Eclipse environment errors in the log file

Sometimes you encounter errors thrown by the Eclipse environment. These errors most often occur when resources such as SWC files are not found at runtime. In these cases, you can see the error messages in the Eclipse Error Log file.

The default location of this log file on Windows is c:\Documents and Settings\user_name\workspace\.metadata\.log.

For Macintosh, the default location is also in the workspace directory, but files and directories that begin with a dot are hidden by default.

Custom build scripts with Apache Ant

You can modify and extend the standard build process by using Apache Ant, which is an open-source Java-based build

tool. For more information about creating custom builders, see “ Customize builds with Apache Ant ” on page 87.

Compiler options

You can modify the default Flex compiler or ActionScript compiler settings that Flash builder uses.

To view or modify the default settings, from the Flash Builder menu, select Project > Properties, and then select Flex

Compiler or ActionScript Compiler, as required.

Flex SDK version

For Flex projects, Flash Builder uses Flex 4.6 as the default SDK. If your project, however, uses a specific version, such as Flex 3.5, Flash Builder compiles applications in the project using the specified Flex SDK.

You can change the default setting to use a specific Flex SDK, or to compile using Flex 3 compatibility. Specifying backward compatibility affects some behavior such as the layout rules, padding and gaps, skins, and other style settings. In addition, it affects the rules for parsing properties files. Setting the compatibility version does not enforce all differences that exist between the versions. For more information, see Backward compatibility.

AIR SDK

For ActionScript projects, Flash Builder uses the AIR SDK that contains the ActionScript compiler. For more

information, see “ Installed AIR SDK ” on page 241.

Adobe Flash Player options

The default version of Flash Player that the compiler uses is the minimum version required by the SDK used for compilation.

You can specify a specific version of Flash Player that you want to target for the application. Features requiring a later version of Flash Player are not compiled into the application.

Compiler options

Flash Builder provides check boxes for the following compiler options:

• Use Flash Text Engine in MX components

This option is available only for Flex projects. The Flash Text Engine (FTE) is a library that provides text controls with a rich set of formatting options. All Spark components in the spark.components package support FTE. See

Some MX controls provide support for FTE. MX controls that support FTE use the same embedded fonts as Spark components using FTE. See Using FTE in MX controls.

• Copy non-embedded files to output folder

• Generate accessible SWF file

This option is available only for Flex projects. Selecting this option enables accessibility features when compiling the application or SWC file. For information on using accessibility features with Flex, see Accessible applications .

• Enable strict type checking

When strict type checking is enabled, the compiler prints undefined property and function calls. The compiler also performs compile-time type checking on assignments and options supplied to method calls.

• Enable warnings

This option enables specified warnings. For more information, see Viewing warnings and errors.

You can also specify multi-line compiler arguments that are available with the command-line, mxmlc compiler. You can set the values of most options in the Additional Compiler Arguments field by using the same syntax as on the command line. For information about the syntax for setting options in the Flex Compiler dialog box, see About the command-line compilers.

In the Additional Compiler Arguments field, you can substitute a path to the SDK directory by using the ${flexlib} token, as the following example shows:

-include-libraries "${flexlib}/libs/automation.swc" "${flexlib}/libs/automation_agent.swc"

HTML wrapper

In addition to generating SWF files for web applications, the Flash Builder compiler also generates an HTML wrapper that you can use when you deploy the application. The following options are available:

• Generate HTML wrapper file

• Check target player version

When enabled, the compiled application checks for the correct version of Flash Player.

If Express Install is enabled, the application runs a SWF file in the existing Flash Player to upgrade users to the latest version of the player.

• Enable integration with browser navigation

This option enables deep linking. Deep linking lets users navigate their interactions with the application by using the Back and Forward buttons in their browser.

Command-line access to the Flex framework compilers

You have direct command-line access to use the Flex framework compilers (mxmlc and compc). For more information, see About the command-line compilers in Using Adobe Flex 4.6

Customize project builds

Flash Builder allows you to build your applications automatically using the default project settings. Using the default project settings is the recommended approach to building your applications. You can, however, customize project builds to suit your needs. For example, you can change the default output folder or modify the compiler options.

Component Set (MX + Spark, Spark Only, or MX Only)

By default Flex projects have the entire component set available to applications in the project. The component set includes Spark components introduced with Flex 4 as well as MX components that were available with Flex 3.

82

Last updated 12/3/2012

USING FLASH BUILDER

Using Projects in Flash Builder

In some scenarios, you may want to use only the MX components that were available with Flex 3, or only the Spark components introduced with Flex 4. For example, suppose you have an existing Flex 3 project and you do not want to introduce the new Spark components. But you do want to take advantage of features introduced with Flex 4 and Flash

Builder 4, such as the new states syntax, compiler improvements, and other language features. In this scenario, you select the MX Only component set. When you select the MX Only component set, all Spark related libraries are removed from the build path. If you convert a Flex 4 project to MX Only, Flash Builder does not modify any of the code in the project. You must manually update your code to remove any references to Spark components and libraries.

Similarly, if you select the Spark Only component set, only the Spark components are used, and any MX-related libraries are removed from the build path.

Application Framework Linkage

By default, application classes for Flex 4 and higher versions of the Flex framework use dynamic linking. Rather than compiling all classes into the application SWF file (static linking), some classes are loaded from the framework runtime shared library (RSL). Applications built with dynamic linking have smaller SWFs, which means they download faster.

However, these applications use more memory because all framework classes are loaded, not just the classes you need.

For more information, see Runtime Shared Libraries.

You can modify a project’s properties to customize this behavior for all applications in a project. After selecting a project, from the Flash Builder menu, select Project > Properties > Library Path.

By default, Flash Builder uses the default behavior of the Flex SDK for framework linkage. For Flex 4 and higher versions, the default behavior is dynamic linking of RSLs. For Flex 3, the default behavior is static linking. Use the

Framework Linkage drop-down list to override the default behavior.

For Flex 4.5 SDK and higher versions of the Flex framework, the following options are enabled by default:

• Verify RSL Digests (Recommended For Production)

Verifies that the digest of the RSL matches the digest that was stored in the application at compile time when the application was linked to the cross-domain RSL. For more information, see About RSL digests.

• Remove Unused RSLs

Removes RSLs that are not used during compile time. Only the RSLs that are used are copied to the output folder.

This option is available only for Flex 4.5 SDK and higher versions of the Flex framework, not older Flex frameworks.

You can, however, force-load an unused RSL during compile time by double-clicking the project library path. Then, select Force Load RSL in the Library Path Item Options dialog box.

You can specify the application domain in which the cross-domain RSLs have to be loaded. You can select Default,

Current, Parent, or Top-Level as the application domain.

For example, if a module uses a specific RSL, you can select Current as the application domain. Then, the specified

RSL is accessible only to that module and not to the application loading the module. Unloading the module automatically unloads the associated RSL also.

Note: Cross-domain RSLs and application domains are supported only in Flex 4.5 SDK and higher versions of the Flex framework, not older Flex frameworks. If you are importing a project that was built using a Flex framework that used standard RSLs, then Flash Builder automatically converts the standard RSLs into cross-domain RSLs.

For more information, see Compile with standard or cross-domain RSLs in Flash Builder.

• Use Local Debug SWF RSL When Debugging

Use local RSLs when debugging the application. Using local RSLs allows you to step into debug RSL files. This option is ignored when exporting a release build.

The Build Automatically option affects all projects in the workspace.

Set up a project output folder

When you create a project in Flash Builder, by default, the build output is generated into the output folder.

You can change the name of this folder when you create the project or after the project is created. You can either create a folder or select an existing folder in the workspace.

1 In the Flex Package Explorer, select a project.

2 Right-click (Control-click on Macintosh) and select Properties from the context menu.

The Project Properties dialog box appears.

3 Select the Flex Build Path properties page.

4 Change the existing output folder by entering a new name or by navigating to an existing folder in your project and selecting it.

Note: You cannot change the output folder of an LiveCycle Data Services ES application in this manner because its location is controlled by the server and is accessible only through the project’s Flex-config.xml file.

5 Click OK.

The new output folder replaces the existing output folder.

Important: When you change the name of the output folder, the original output folder and all of its contents are deleted.

Rebuild the project to regenerate the application SWF file and HTML wrapper files.

Modify a project build path

Each project has its own build path, which is a combination of the source path and the library path. (Library project

build paths are a little more complex. For more information, see “ Create Flex library projects ” on page 182.) The

source path is the location of the project MXML and ActionScript source files. The library path is the location of the base Flex framework classes and any custom Flex components that you have created, in the form of SWC files.

Modify the source path

1 Select a project in the Flex Package Explorer.

2 Right-click (Control-click on Macintosh) and select Properties from the context menu. The Project Properties dialog box appears.

3 Select the Flex Build Path properties page. (If you’re working with an ActionScript project, select the ActionScript

Build Path properties page.)

4 Add a folder to the source path by clicking the Add Folder button.

5 Enter a name for the folder or click the Browse button to select the location of the custom classes.

You can also use path variables rather than entering the full path to the file system. You can either enter the name

of an existing path variable or create a path variable; for more information, see “ Create a path variable ” on page 85.

6 Modify the source path as needed, and click OK.

Modify the library path

1 Follow steps 1 through 3 of the previous procedure to access the Flex Build Path properties page.

2 Click the Library Path tab.

The library path contains references to the Flex framework classes, which are contained in SWC files. A SWC file

is an archive file for Flex components and other assets. For more information, see “ Use SWC files in your projects ” on page 184.

You can edit the path to the framework or, if you created custom Flex components, add new folders or SWC files to the library path. You can also remove items from the path.

3 Modify the library path as needed, and click OK.

Create a path variable

Rather than linking to resources by entering the full path to the local or network folder where you store your files, you can define path variables. For example, you can define a path variable called Classes and then set the path to a folder on the file system. You then select Classes as the location of the new linked folder. If the folder location changes, you can update the defined path variable with the new location and all the projects that are linked to Classes continue to access the resources.

Set or create a path variable

1 Select a project in the Flex Package Explorer.

2 Right-click (Control-click on Macintosh) and select Properties from the context menu. The Project Properties dialog box appears.

3 Select the Flex Build Path properties page. (If you’re working with an ActionScript project, select the ActionScript

Build Path properties page.)

4 You can create a path variable for any item on the path (including folders in the source path and SWC folders, projects, and SWC files in the library path). For example, in the Source Path tab, click Add Folder. The Add Folder dialog box appears.

5 Enter a path variable using the following format: ${ pathvariablename } .

Note: If the variable does not exist, the path entry fails. The list of existing resource variables is available by selecting also manage linked resource variables on this properties page.

6 Click OK to add the path variable to the path.

Advanced build options

Flash Builder has advanced options for customizing project builds. You can, for example, builds projects manually, change the default build order of projects in the workspace, and create custom builders using the Apache Ant utility.

Using Projects in Flash Builder

Build projects manually

When you build projects manually, you can control the timing and scope of the build. For example, you can build a single project, all projects in the workspace, or create a working set of projects or selected project resources and build only those projects and resources. A working set is a collection of workspace resources (projects, files, and folders) that

you can select and group together and work with as you see fit. For more information about working sets, see “ Create working sets ” on page 109.

Build a single project

1 In the Flex Package Explorer, select the project you want to build.

2 Select Project > Build Project from the main menu.

The selected project is built, and new or updated release and debug application files are added to the project output folder.

Note: If any of your project files need to be saved, you are prompted to do so before the build begins. To bypass this save prompt, you can set workspace preferences to save files automatically before a build begins.

Build all projects in the workspace

❖ Select Project > Build All from the main menu.

All projects in the workspace are built and application files are added to each project output folder. You are then prompted to save files if you have not already chosen to save files automatically before a build begins.

Build a working set

Do either of the following:

• Select Project > Build Working Set

For more information about creating a working set, see “ Create working sets ” on page 109.

• Choose an existing working set by selecting Project > Build Working Set

All projects in the working set are built and the application files are added to the project output folder.

Save project resources automatically

When you build your projects manually, you are prompted to save all resources before the build begins. To bypass this prompt, you can set workspace preferences to automatically save project resources.

1 Open the Preferences dialog, select General > Workspace.

2 Select the Save Automatically Before Build option.

3 (Optional) You can modify how often resources are saved by entering a value (in minutes) for the Workspace Save

Interval.

Perform a clean build

After a project has been built, subsequent builds affect only the resources that have been added or modified. To force the Flash Builder compiler to rebuild all resources in a project, you can perform a clean build. You can perform a clean build if, for example, you want to eliminate all potential sources of a problem you encountered when testing your application.

1 Select Project > Clean from the main menu.

2 Select the project (or projects) whose build files you want to discard and rebuild from scratch.

3 Click OK.

Using Projects in Flash Builder

Change the project build order

Flash Builder lets you create relationships between projects when working with multiple projects in the workspace. For example, you can import ActionScript classes from one project into another. Creating relationships between projects affects the order in which your projects are built.

By default, the compiler builds related projects in the order required to build them all properly. For example, if a project refers to classes contained in another project, the project containing the classes is built first. In most cases, relying on the compiler to build projects in the proper order is sufficient and your applications is generated successfully.

You can, however, change the build order. For example, you can change the build order if you created a custom Ant builder and associated it with a project in your workspace, and you have to build that project before other projects are

built. For more information about creating custom builders, see “ Customize builds with Apache Ant ” on page 87.

1 Open the Preferences dialog and select General > Workspace > Build Order.

The Build Order dialog box displays the following options:

Use Default Build Order The default build order is dictated by the dependencies between projects and is handled by the compiler.

Project Build Order You can manually set the build order for all the projects in the workspace. You can also remove a project from the build order list; it will still be built, but only after all the projects in the build order list.

Max Iterations When Building With Cycles If your projects contain cyclic references (something you should avoid), you can set the number of build attempts so that the compiler can properly build all the projects. The default maximum number of iterations is 10.

2 Modify the build order as needed, and click OK.

Customize builds with Apache Ant

By creating a custom builder, you can modify and extend the standard build process. Flash Builder contains a standard build script that is used to compile your applications. If needed, you can create custom build scripts using Apache Ant, which is an open-source Java-based build tool.

You can apply custom builders to all the Flash Builder project types.

Create a builder

1 In the Flex Package Explorer, select a project and then right-click (Control-click on Macintosh) to display the context menu and select Properties.

2 Select the Builders properties page. If you’re using other Eclipse plug-ins, there can be more than one builder listed.

Flash Builder provides a builder named Flex, which you cannot modify.

3 Select New.

4 In the Choose Configuration Type dialog box, select the appropriate configuration type. Flash Builder supports the program type. Select it and click OK to continue. From the new builder properties page, you define the builder properties and reference the Ant script (an XML file).

5 Click OK to apply it to the project.

Detailed information about working with Ant build scripts can be found in the Eclipse documentation at help.eclipse.org/help31/index.jsp

USING FLASH BUILDER

Using Projects in Flash Builder

Using multiple SDKs in Flash Builder

Flash Builder lets you change the version of the SDK that you use to compile your projects. You can select the SDK when you first create a project or at any time you are working on a project.

The combination of a framework and the compiler make up the SDK. If you select the Flex 4 SDK, then you are using the 4 version of the Flex framework SWC files, and the 4 version of the Flex compiler. You cannot use, for example, the Flex 4 compiler with the Flex 3 framework SWC files.

Using a different SDK can be useful if you are given a project that was developed using Flex Builder 3 (which uses the

Flex 3 SDK), but you are running Flash Builder 4 (which uses the Flex 4 SDK by default). By selecting an older SDK to build with, you can maintain projects that have not been updated to be compatible with the latest version of the SDK.

In addition, if you are currently working on a project for the Flex 3 SDK, but want to use the Flash Builder 4 features, you can upgrade your edition of Flash Builder, but then select the older SDK as the de1fault SDK.

If you develop a project and then change the SDK, Flash Builder performs a full rebuild, not an incremental build. As a result, Flash Builder flags any differences that would throw compiler errors as if the project had been developed under the original SDK.

Flash Builder also regenerates all supporting files for the projects. These include the history management and deep linking files used by the HTML wrapper. For Flex 4 SDK projects, Flash Builder creates the Flex 4 SDK–compatible history.swf, history.html, and history.js history management files in the html-templates directory. For Flex 3 SDK projects, Flash Builder creates the Flex 3 SDK–compatible deep-linking history.htm, history.js. and historyFrame.html files in the html-templates/history directory.

In addition, the availability of Flash Builder options change depending on the selected SDK. For example, if you add a module to your project with a project that uses the Flex 3 SDK, Flash Builder does not let you select whether you want to optimize that module or not. You must do this manually.

For more information about the differences between the Flex 4 SDK and the Flex 3 SDK, see Backward compatibility.

When you create a Flex project, Flash Builder uses the default SDK. The default is the latest SDK that shipped with

Flash Builder, but you can change it to any SDK that is visible in the list of available SDKs in Flash Builder.

When you create a Flex library project or ActionScript project, you can select which SDK you want that project to use in the New Flex Library Project and New ActionScript Project dialog boxes.

Add a Flex SDK to the list of available SDKs

1 Open the Preferences dialog and select Flash Builder > Installed Flex SDKs.

The currently installed SDKs are listed. The default SDK has a check mark next to its name.

2 Click Add.

3 Enter the location of the SDK in the Flex SDK Location field.

4 Enter a name for the SDK in the Flex SDK Name field. Do not use the name of an existing SDK for this field.

5 Click OK to save your changes.

6 Click OK again to add the new SDK to the list of available SDKs. This list is maintained in the Flash Builder workspace, across Flex projects. The next time you create a project, the list of available SDKs includes this new SDK.

Change the SDK version for the current project

1 Select Project > Properties.

2 Select Flex Compiler.

3 Click Use a Specific SDK.

USING FLASH BUILDER

Using Projects in Flash Builder

4 Select the SDK you want to use from the drop-down list. If the SDK you want to use is not in the drop-down list, click the Configure Flex SDKs link.

5 Click OK.

Flash Builder applies the new SDK to the current project. Errors and warnings can appear if the project uses code that is not compatible with the new SDK.

Select a new default SDK

1 Open the Preferences dialog, select Flash Builder > Installed Flex SDKs.

The default SDK has a check mark next to its name.

2 Select the check box next to an SDK. This SDK becomes the default SDK. It is also applied to any project that has the Use Default SDK option selected in the Flex Compiler dialog box, including the current project. If the current project is set to use a specific SDK, then it continues to use that specific SDK, even if you change the workspace’s default SDK to a different one.

3 Click OK to save your changes.

4 Click OK again.

Alternatives to using project references

Project references can affect build order, so Flash Builder provides alternatives to using project references.

Flex Library projects The preferred way to create a reusable library. Flash Builder creates a project reference to ensure that the SWC project is built before the main project that includes it on the library path. Also, because Flash Builder adds it to the library path, code hints appear in the main project for the classes in the SWC project.

Source path The recommended way to include code in your project that is not under the same folder structure. This enables code hints in the project files and classes in related files, and the compiler knows where to find the source code.

You can add any number of source paths to your project and they are displayed as linked folders in the Package

Explorer.

Flash Builder command line build using Apache Ant

Flash Builder provides the Ant task <fb.exportReleaseBuild>. Use this task to implement command line builds that synchronize a developer’s individual build settings with the nightly build. Alternatively, you can use the <mxmlc> task in custom scripts for nightly builds.

Note: Command line build support is available only in Flash Builder Premium.

<fb.exportReleaseBuild> task

Using the <fb.exportReleaseBuild> task ensures that the nightly build’s settings exactly match the settings used by developers during their daily work.

For example, if a developer changes the library path of a Flex project, the new library path is written to the Flash Builder project. When the nightly build machine runs <fb.exportReleaseBuild>, that task loads the Flash Builder project and all of its settings.

Another advantage of using <fb.exportReleaseBuild> is that it automatically takes care of additional “housekeeping” tasks normally included in a Flash Builder build, such as:

• Automatically compile associated library projects

• Copy assets such as JPEGs, and so on, into the output directory

89

Last updated 12/3/2012

USING FLASH BUILDER

Using Projects in Flash Builder

• Copy the HTML template, including macro substitution based on the compilation results (such as width and height)

Note: The <fb.exportReleaseBuild> task requires you to install Flash Builder on the nightly build machine.

<mxmlc> task

If you write a custom script that uses the <mxmlc> task (for example, an Ant script), then you do not need to install

Flash Builder on the build machine. However, the build machine is required to have the Flex SDK available. Thus, the build machine can be on a Linux platform.

However, the disadvantage of this approach is that you have two sets of build settings to synchronize. That is, one in

Flash Builder, used by developers during their daily work, and another on your nightly build machine.

<fb.exportReleaseBuild> usage

1 Install Flash Builder on a build machine.

2 Write build.xml

with fb.exportReleaseBuild as a target. For example:

<?xml version="1.0"?>

<project default="main">

<target name="main">

<fb.exportReleaseBuild project="MyProject" />

</target>

</project> build.xml

specifies to run a command line build of your Flex project, using the settings saved in your project files.

See “ Parameters for fb.exportReleaseBuild task ” on page 91 for details on available parameters.

3 Create a nightly build script that tells Eclipse to look for a build file and execute its target.

The following examples specify build.xml

as a build file, which executes MyTarget.

If your nightly build script is on a Macintosh platform, you could run the following script:

WORKSPACE="$HOME/Documents/Adobe Flash Builder"

# works with either FlashBuilder.app or Eclipse.app

"/Applications/Adobe Flash Builder/FlashBuilder.app/Contents/MacOS/FlashBuilder" \

--launcher.suppressErrors \

-noSplash \

-application org.eclipse.ant.core.antRunner \

-data "$WORKSPACE" \

-file "$(pwd)/build.xml" MyTarget

If your nightly build is on a Windows platform, you could run the following batch file: set WORKSPACE=%HOMEPATH%\Adobe Flash Builder

REM works with either FlashBuilderC.exe or eclipsec.exe

"C:\Program Files\Adobe\Adobe Flash Builder 4.6\FlashBuilderC.exe" ^

--launcher.suppressErrors ^

-noSplash ^

-application org.eclipse.ant.core.antRunner ^

-data "%WORKSPACE%" ^

-file "%cd%\build.xml" MyTarget

Export Release Build wizard

When you run the Export Release Build wizard (Project > Export Release Build), the settings you make in the wizard are saved in the .actionScriptProperties file. A command-line build that uses fb.exportReleaseBuild task picks up the settings from the wizard. The Export Release Build wizard saves the following settings:

• View Source

The source files you specify for View Source are saved. If you specify the publishsource parameter to fb.exportReleaseBuild, then the wizard includes these files as viewable source files.

Important: For server projects, you can select the services folder when exporting source files. Exporting files that implement services has security implications. These files can expose access to your database, including user names and passwords. See Exporting source files with release version of an application.

• For Adobe AIR projects, any additional output files that you specify in the wizard to include with the AIR or AIRI file.

Run command line builds on Linux and other platforms

The <fb.exportReleaseBuild> task is only supported on Windows and Mac platforms.

However, if you are writing a build script for another platform, use the -dump-config option to the mxmlc or compc compiler to write compiler configuration settings to a file. You can then use the -load-config option to read the configuration options.

Run a command line build using Flash Builder compiler settings

1 In Flash Builder, select Project > Properties > Flex Compiler

2 In Additional Compiler Arguments, specify the following argument:

-dump-config pathname, where pathname specifies the absolute path to a file on your system.

3 Apply the changes in the Project window.

The compiler settings are written to the specified file. Remove the -dump-config argument after you have verified that the file has been written.

4 Modify the configuration settings as necessary.

5 In your build script, run the compiler so it includes the saved compiler settings: mxmlc -load-config pathname

Limitations to command line builds

There are a few limitations to running command line builds using the <fb.exportReleaseBuild> task.

Run command line builds on 64-bit platforms

Flash Builder runs on platforms that implement 32-bit Java. To run a command line build on platforms that support

64-bit Java (for example, Mac OS X 10.6), add -d32 to the command-line options that are passed to Java. For example: java -d32 ...

Publish source code

When your applications are ready to be released, Flash Builder lets you choose whether users can view source code and assets in the application. As with HTML, users can access and view the source in a web browser by selecting View

Source from the context menu. The source viewer formats and colors the code so that it is easy to read. It is also a convenient way to share code with other Flex and ActionScript 3.0 developers.

Enable the view source option

1 With the completed application project open in the editor, select Project > Export Release Build.

2 Select Enable View Source or Include Source for ActionScript projects.

3 Click Choose Source Files.

4 In the Publish Application Source dialog box, select the application file or files to include in the View Source menu.

By default, the main application file is selected.

Important: For server projects, you can select the services folder when exporting source files. Exporting files that implement services has security implications. These files can expose access to your database, including user names and passwords. See Exporting source files with release version of an application.

5 (Optional) Change the source output folder. By default, a source view folder is added to the project output folder.

6 Click OK.

Last updated 12/3/2012

USING FLASH BUILDER

Using Projects in Flash Builder

When users run your application, they can access the source code by selecting View Source from the context menu.

The source code appears in the default web browser as a source tree that reflects the structure of the resources

(packages, folders, and files) contained in your application (the ones that you decided to publish). Selecting a source element displays the code in the browser. Users can also download the entire set of source files by selecting the

Download.zip file link.

Note: Because of Internet Explorer security restrictions, you are sometimes unable to view the source on your local development computer. If so, deploy the application to a web server to view the source.

Add the view source menu to ActionScript projects

In Flex projects, you add the View Source option to your application with the Export Release Build wizard. In

ActionScript applications, you add this option manually.

The Flex framework contains the following function that you can use in an ActionScript application’s constructor to enable the view source menu: com.adobe.viewsource.ViewSource.addMenuItem(obj:InteractiveObject, url:String, hideBuiltins:Boolean = true)

You can use the code in your ActionScript applications as shown here: package { import flash.display.MovieClip; import com.adobe.viewsource.ViewSource; public class MyASApp extends MovieClip

{ public function MyASApp()

{

ViewSource.addMenuItem(this, "srcview/index.html");

}

// ... additional application code here

}

}

This example demonstrates adding the view source menu using the default location of the source folder (srcview). If you change the location of the source folder, make sure that your code uses the correct location.

95

Run and debug applications

Your applications are run (and debugged) based on a launch configuration. When you create new Flex and

ActionScript applications, a launch configuration specifies the location of the built applications files and the main application file. You can modify the launch configuration or create custom launch configurations. For more

information, see “ Create custom launch configurations ” on page 99.

You can run your projects in a number of ways in Flash Builder. For example, you can use the Run command, which is available from the workbench main menu and toolbar, from the Flex Package Explorer, and code editor pop-up menus.

Last updated 12/3/2012

USING FLASH BUILDER

Using Projects in Flash Builder

Note: The Run button has two elements: the main action button, and a pop-up menu that shows the application files in the project that can be run or debugged. When you click the main action button, the default application file is run.

Alternatively, you can click the pop-up menu and select any of the application files in the project and create or edit a launch configuration in the Create, Manage, and Run Configurations dialog box.

Manage launch configurations

Launch configurations are used both to run and to debug applications. Flash Builder provides a default launch configuration for Flex and ActionScript applications.

A launch configuration defines the project name, main application file, and the path to the run and debug versions of the application. Flash Builder contains a default application launch configuration that is used to create launch configurations automatically for each of your projects.

Create or edit launch configurations to run or debug web applications

When you create and build a project, it is ready to be run or debugged. Both running and debugging of the applications in your project are controlled by a launch configuration. By default, Flash Builder creates a launch configuration for each of the application files in your project the first time you run or debug them. The configurations are based on the default application configuration, and you can edit them as necessary.

Launch configurations are managed in the Create, Manage, and Run Configurations dialog box.

4 Specify a Launch Method:

• On AIR Simulator

Runs the application on your desktop using the AIR Debug Launcher, according to a specified device configuration. This launch method is not a true emulation of running the application on a device. However, it does allow you to view the application layout and interact with the application.

See “ Preview applications with ADL ” on page 217.

Click Configure to edit device configurations. See “ Set device configurations ” on page 204.

• On Device

Install and run the application on your device.

Flash Builder installs the application on your device and launches the application. Flash Builder accesses the

device connected to your computer’s USB port. See “ Test and debug a mobile application on a device ” on page 218for more information.

Windows platforms require a USB driver to connect an Android device to your computer. For more

information, see “ Install USB device drivers for Android devices (Windows) ” on page 212.

• On iOS Simulator (Apple iOS platform only)

Important: The iOS simulator is supported only on Mac and not on Windows.

The iOS Simulator offers a fast way to run and debug iOS applications without using a device. For more

information, see “ Test and debug an iOS application on a simulator ” on page 217

5 Select the build target, and click Apply.

When you specify a launch configuration to run or debug an application, Flash Builder picks up the applicable build target settings by default. For example, when you create a launch configuration to debug on a device, the target build is selected as "device" by default. You can, however, change the default selection and select a custom build target that

you created. For more information on creating build targets, see “ Project properties for packaged mobile projects ” on page 107.

Check for connected devices

When you run or debug a mobile application on a device, Flash Builder checks for connected devices. If Flash Builder finds a single connected device online, Flash Builder deploys and launches the application. Otherwise, Flash Builder launches the Choose Device dialog for these scenarios:

• No connected device found

• Single connected device found that is offline

• Multiple connected devices found

The Choose Device dialog lists the devices and their state (online or offline). Select the device to launch.

Debug mobile applications

You can debug a mobile application from your development desktop or from a device. Before you can debug a mobile

application, create a launch configuration. See “ Manage launch configurations ” on page 96.

Debugging on an Android device requires Android 2.2 or a later Android version installed on it. When you run an application on a device from Flash Builder, Flash Builder installs a debug version of the application on the device.

For more information, see “ Debug an application on a Google Android device ” on page 218.

Debug version of the application

The debug version of your application contains debugging information that is used when you debug your application.

The Export Release Build version does not include the additional debugging information and is therefore smaller in size than the debug version. An HTML wrapper file contains a link to the application SWF file and is used to run or debug your application in a web browser.

Note: Both the Run and Debug commands launch the development build in the bin-debug folder (not the exported release build folder, bin-release.)

Using Projects in Flash Builder

Run and debug applications in a browser

By default, the launch configuration for web applications specifies that the run and debug paths point to the HTML wrapper files in the output folder of your project; therefore, your applications are run and debugged in Flash Player running in a web browser. Alternatively, you can run and debug your applications in the stand-alone Flash Player (see

“ Run the application SWF file in the stand-alone Flash Player ” on page 101). You can also override the system default web browser setting and run your applications in any browser you have installed (see “ Change the default web browser ” on page 101).

Change the default web browser

Flash Builder uses the system default web browser when running and debugging applications. While you cannot set each launch configuration to use a specific web browser, you can change the workbench web browser setting, which affects how all of your applications are run and debugged.

1 Open the Preferences dialog and select General > Web Browser.

2 Select a web browser from the list of web browsers installed on your system.

Note: The Use Internal Web Browser option does not apply to running and debugging applications. Applications are always run and debugged in an external web browser.

You can also add, edit, and remove browsers from the list.

3 Click OK to apply your changes.

Run the application SWF file in the stand-alone Flash Player

You can choose to run and debug your applications in the stand-alone Flash Player by making a simple change to the launch configuration. You can specify the Flash Player version to use when you run and debug your applications. For

more information, see “ Stand-alone Flash Player version management ” on page 236.

Run and debug applications in the stand-alone Flash Player

1 Select Run > Run Configurations from the Flash Builder menu.

2 From the Create, Manage, and Run Configurations dialog box, select the launch configuration that you want to modify.

3 In the Main tab, deselect Use Defaults.

4 Under URL Or Path To Launch, click Browse.

The file selection dialog box appears and lists the contents of the build output folder.

5 Select the application SWF file in the bin-debug directory. Do not select the SWF file in the bin-release directory, if there is one. This SWF file does not contain debug information.

6 Click Open to select the file and return to the configuration dialog box.

7 Apply your changes and use the modified configuration to run or debug the application.

Compare debug and non-debug versions of your application

By default, Flash Builder generates debug versions of your application’s SWF file and stores them in your project’s bindebug directory. This application is larger than the non-debug version because it includes additional code and metadata that the debugger uses.

Using Projects in Flash Builder

To generate a non-debug version of your application, you can do one of the following:

• Select Project > Export Release Build. Doing so, creates a non-debug SWF file or AIR file in the bin-release directory.

• Add -debug=false to the Additional Compiler Arguments field. Doing so, generates a non-debug SWF file no matter where you export it to.

Export a release version of an application

After you have finished creating your application and want to publicly release it, you can export a release version of your application. Flash Builder’s Export Release Build wizard creates an optimized release-quality version (non-debug

SWF file or AIR file) of your application.

Depending on the type of application, the wizard guides you through steps to customize and optimize packaging.

After running the wizard, additional steps are required to deploy your application on a server.

Export a web application (runs in Adobe Flash player)

1 Select Project > Export Release Build to open the Export Release Build wizard.

2 Select the project and application you want to export.

3 (Optional) Select Enable View Source to make application source files available from the exported application.

Click View Source Files to specify which source files to include. In addition to the specified source files, the wizard generates a ZIP archive file containing the source files.

Important: For server projects, you can select the services folder when exporting source files. Exporting files that implement services have security implications. These files can expose access to your database, including user names and passwords. See Exporting source files with release version of an application.

4 Click Finish.

5 Copy the folder containing the exported release to the web root of the server hosting the application.

6 (Server projects) If exporting a release from a project that specified an application server type, deploy the services and other server-side files to the web root of the target server.

Maintain the same directory structure used during development.

This step applies to ColdFusion, PHP, BlazeDS, and Data Services. You specify the application server type when creating a project in Flash Builder.

If the application server is on a different host than the deployed application, a cross-domain policy file is necessary to access these services. This applies to projects accessing static XML service files or local files for HTTP services or web services. See Using cross-domain policy files.

7 (PHP server projects only) For PHP projects, perform these additional steps: a Install the Zend framework on the server. See Installing Zend Framework.

b Modify the amf-config.ini

file, which is in the output folder of the exported release:

For zend_path , specify the absolute path to the Zend installation directory.

Set amf.production

to true.

Update webroot with the absolute path to the web root on the server.

Digitally sign your Adobe AIR applications

When exporting a release version of your application, you need to digitally sign your Adobe AIR application. You have the following options:

• You can sign the application using a commercial code signing certificate.

• You can create and use a self-signed digital certificate.

• You can package the application now and sign it later.

Digital certificates issued by certification authorities such as VeriSign, Thawte, GlobalSign, and ChosenSecurity assure your users of your identity as a publisher. The digital certificates also verify that the installation file has not been altered since you signed it. Self-signed digital certificates serve the same purpose but they do not provide validation by a third party.

You also have the option of packaging your Adobe AIR application without a digital signature by creating an intermediate AIR file (.air). An intermediate AIR file is not valid in that it cannot be installed. It is instead used for testing (by the developer) and can be launched using the AIR ADT command line tool. Adobe AIR provides this capability because in some development environments a particular developer or team handles signing. This practice insures an additional level of security in managing digital certificates.

For more information about signing applications, see Signing AIR applications in Adobe AIR documentation.

Digitally sign your Adobe AIR application

You can digitally sign your Adobe AIR application by selecting an existing digital certificate or by creating a new selfsigned certificate.

Chapter 5: Debugging Tools in Flash

Builder

After your projects are built in to applications, you can debug them in Flash Builder.

Debugging is similar to running your applications. However, when you debug you control when the application stops at specific points in the code. You can also control whether you want it to monitor important variables, and you can test fixes to your code.

The Flash Debug perspective

The Flash Debug perspective provides an extensive set of debugging tools that let you:

• Set and manage breakpoints

• Determine how to suspend, resume, and terminate the application

• Step into and over code

• Watch variables

• Evaluate expressions

110

Last updated 12/3/2012

USING FLASH BUILDER

Debugging Tools in Flash Builder

You add breakpoints to executable lines of code in the code editor. The Debug perspective appears automatically when the first breakpoint is reached. The Flash Debug perspective is then activated and you can inspect the state of and

manage the application by using the debugging tools. For more information, see “ Start a debugging session ” on page 113.

You can also switch to the Debug perspective manually by selecting it from the Perspective bar. The Perspective bar is at the right edge of the main workbench toolbar. The Debug perspective contains Debug, Breakpoints, Console,

Variables, and Expressions views.

The Debug view

The Debug view is the control center of the Flash Debug perspective. You use it to control the execution of the application, to suspend, resume, or terminate the application, or to step into or over code.

The Debug view (in other debuggers it is sometimes referred to as the callstack) displays the stack frame of the suspended thread of the application you are debugging.

111

Applications built with Flex are single-threaded (not multi-threaded like Java, for example) and you can debug only one application at a time. Therefore, when you debug an application, you see only the processes and Debug view for a single thread of execution.

The Debug view shows a list of all the functions called to that point, in the order called. For example, the first function called is at the bottom of the list. You can double-click a function to move to it in the script; Flash Builder updates the information in the Variables view to reflect the new location in the script.

Breakpoints view

The Breakpoints view lists all of the breakpoints you set in your project. You can double-click a breakpoint and display its location in the editor. You can also disable, skip, and remove breakpoints.

Console view

The Console view displays the output from trace statements placed in your ActionScript code and also feedback from the debugger like, status, warnings, errors, and so on.

Variables view

The Variables view displays information about the variables in a selected stack frame. You can select variables to monitor (in the Expressions view) and also change variable values during the debugging session. During the debug session, you can see the changes in the currently running SWF file and experiment with fixes for the problem you have to resolve.

The Variables view uses icons and overlays to provide visual cues about the type of variable.

The Variables view

Complex variables can be expanded to display their members. You use the Variables view to watch variables by adding them to the Expressions view and to modify the value of variables during the debugging session. You can also set

watchpoints in the Variables view, as described in “ Use watchpoints ” on page 119.

All superclass members are grouped in a separate tree node; by default you see only the members of the current class.

This grouping helps reduce excess numbers of variables that are visible at one time in Variables view.

Expressions view

The Expressions view is used to monitor a set of critical variables. You can choose the variables you consider critical in the Variables view and add them to the Expressions view for monitoring. You can also add and evaluate watch expressions. Watch expressions are code expressions that are evaluated whenever debugging is suspended.

Debug your application

Both running and debugging use a configuration to control how applications are launched. When you debug your

application, you run the debug version of the application file. See “ Debug version of the application ” on page 99.

You can edit the launch configuration to change the default main application file. You can also modify the default

launch path to run or debug in the stand-alone Flash Player rather than in a web browser. See “ Run the application

SWF file in the stand-alone Flash Player ” on page 101.

While debugging mobile applications, you use the launch configuration to specify whether to launch the application on the desktop or on a device connected to your computer.

Note: The Debug button has two elements: the main action button and a drop-down list. The drop-down list shows the application files in the project that can be run or debugged. When you click the main action button, the project’s default application file is debugged. You can alternatively click the drop-down list and select any of the application files in the project to debug. You can also access the launch configuration dialog box and create or edit a launch configuration by selecting the Debug command.

You can also select Run > Debug.

If your project has not been built yet, Adobe® Flash® Builder™ builds and runs it in debug mode.

3 Your application appears in your default web browser or the stand-alone Flash Player and you can then use the

Flash Builder debugger to interact with it.

4 When a breakpoint is reached, the Flash Debug perspective is activated in the workbench.

Start a debugging session in the plug-in configuration

The Debug command works differently in the plug-in configuration of Flash Builder. Instead of running the selected project, it debugs the most recently launched configuration. You can also select from a list of recently launched configurations.

Debug an Adobe AIR application

Flash Builder provides full debugging support for Adobe AIR applications.

1 Open a source file for the application (such as an MXML file) in Flash Builder.

2 Click on the main workbench toolbar.

The application launches and runs in the ADL application (the AIR Debugger Launcher). The Flash Builder debugger catches any breakpoints or runtime errors and you can debug the application like any other application that is built in

Flex.

Debug an application with ActionScript workers

Flash Builder supports debugging applications with multiple ActionScript workers. The main thread as well as all the supported worker threads are displayed in the Debug view as follows:

115

You can set breakpoints in your worker files. While debugging, Flash Builder lets you step into or out of statements for a specific worker.

You can suspend or resume a specific worker by selecting it and using the appropriate buttons in the Debug View toolbar.

Important: You cannot terminate a specific worker thread. If you choose to terminate it, the debug session is terminated and the application running on your desktop or device is killed.

Each ActionScript worker thread can have its own running state, call stack, and variables. Select the call stack to display variables from that worker. The Expressions view displays only those expressions relevant to the selected call stack.

All other debugging features also work based on the call stack that you select. For example, if you are evaluating an expression, the first part of the expression is resolved using the selected call stack. After that, subsequent debug actions on the expression, like member access, function calls, and such, are based on the worker ID determined from the first part of the expression.

Add and remove breakpoints

You use breakpoints to suspend the execution of your application. By doing so, you can inspect your code and use the

Flash Builder debugging tools to explore options to fix any errors. You add breakpoints in the code editor and then manage them in the Breakpoints view when you debug your applications.

You add breakpoints to executable lines of code. The debugger stops only at breakpoints set on lines that contain the following:

• MXML tags that contain an ActionScript event handler, such as <mx:Button click=" dofunction ()" ...>

• ActionScript lines such as those enclosed in an <mx:Script> tag or in an ActionScript file

Last updated 12/3/2012

USING FLASH BUILDER

Debugging Tools in Flash Builder

• Any executable line of code in an ActionScript file

You can set breakpoints as you write code or while you debug.

Set a breakpoint in the code editor

1 Open a project file that contains ActionScript code.

2 Locate the line of code on which you want to set a breakpoint, and double-click in the marker bar to add a breakpoint.

The marker bar is along the left edge of the code editor.

A breakpoint marker is added to the marker bar and to the list of breakpoints in the Breakpoints view of the Flash

Debug perspective.

When the debugger encounters a breakpoint, the application is suspended, the Flash Debug perspective is displayed, and the line of code is marked with a breakpoint. The line of code is highlighted in the code editor. You then use the

debugging commands in the Breakpoints view toolbar to interact with the code. See “ Breakpoints view ” on page 111.

Remove a breakpoint in the code editor

❖ In the marker bar, double-click an existing breakpoint.

The breakpoint is removed from the marker bar and the Breakpoints view of the Flash Debug perspective.

Remove breakpoints in the Breakpoints view

You can remove one, a few, or all of the breakpoints in the Breakpoints view from the Breakpoints toolbar.

• Select one or more breakpoints from the list of breakpoints, and then click Remove Selected Breakpoints.

• To remove all the breakpoints in a single action, click Remove All Breakpoints.

You can also disable the breakpoints and re-enable them at a later time.

Set conditional breakpoints

You can specify conditions for breakpoints to stop the debugger from executing when specific conditions are met.

When you set a conditional breakpoint, you specify an ActionScript expression that is evaluated during the debugging session. You configure the conditional breakpoint to stop execution for any of the following conditions:

• The expression evaluates to true.

• The value of the expression changes.

• A specified Hit Count has been reached.

How to set a conditional breakpoint

1 From the context menu for a breakpoint, select Breakpoint Properties.

2 In the Breakpoint Properties dialog, specify any of the following:

• Enabled

Toggle to enable or disable the breakpoint.

• Hit Count

Select Hit Count to enable a counter for the breakpoint. Specify a number for the Hit Count.

If you specify both Hit Count and Enable Condition, the Hit Count is the number of times that the specified condition is met (evaluates to true or the value of the condition changes).

Last updated 12/3/2012

116

USING FLASH BUILDER

Debugging Tools in Flash Builder

If you specify Hit Count only, then Hit Count is the number of times the breakpoint has been reached.

• Enable Condition

Select Enable Condition and enter an ActionScript expression to evaluate. See “ Examples of expressions ” on page 117for information on types of expressions supported for evaluation.

Note: Flash Builder checks the syntax of the expression and notifies you of syntax errors. If you have an assignment operator in the expression, Flash Builder displays a warning.

• Suspend when:

Specify when to stop execution, either when the expression for the condition evaluates to true or the value of the expression changes.

Manage variables in the Variables view

Change the value of a variable

1 Select the variable to modify.

2 Right-click (Control-click on Macintosh) to display the context menu and select Change Value.

3 Enter the new value and click OK.

The variable contains the new value.

Modified variables are displayed in red.

Find variables

❖ To locate a variable or variable member in the Variables view, with the Variables view selected, begin entering the name of the variable you’re looking for. You can also use the wildcard character (*) to search for words that occur anywhere within a variable name (for example, “*color”).

Use the Expressions view

While debugging, you can inspect and modify the value of the variables that you selected to watch. You can also add watch expressions, which are code expressions that are evaluated whenever debugging is suspended. Watch expressions are useful for watching variables that may go out of scope when you step into a different function and are therefore not visible in the view.

You can also hover the pointer over an expression or variable in the source editor to see the value of that expression or variable as a tooltip. You can add the expression to the Expressions view by right-clicking and selecting Watch from the menu.

Examples of expressions

The Flash Builder Debugger supports a wide range of simple and complex expressions. The following table lists examples of expressions that can be evaluated during a debugging session. This is not the complete list of expressions supported, but just a sampling of what you can do.

Tracks the index of the ‘@’ character.

Tracks the character at a specific position in a string. String constants are supported.

employees is an XML variable. This type of expression is useful for debugging E4X applications.

Reserved words representing values in expressions.

Most ActionScript operators are supported.

Functions resolved to a class.

Functions resolved using the keyword this .

String is actually a function, not a class, and String.fromCharCode is actually a dynamic member of that function.

Can be valuated only if myStaticFunc is visible from the current scope chain

Can be valuated only if myMemberFunc is visible from the current scope chain.

Math functions are supported.

Regular expressions are supported.

Creation of arrays.

Instantiation of classes.

Correctly handles string plus Integer.

Logical shift operations supported.

Performs arithmetic operations correctly.

Limitations of expression evaluation

There are some limitations to expression evaluation.

• Namespaces are not supported.

• Inline objects are not supported.

• The keyword super is not supported.

• Fully qualified class names are not supported.

For example, you cannot evaluate mx.controls.Button.

You can refer to the unqualified class name. For example, you can specify Button to refer to mx.controls.Button.

If a class name is ambiguous (two classes with the same name in different packages,) then you cannot control which class will be evaluated. However, you can specify: getDefinitionByName("mx.controls.Button")

• Most E4X expressions can be evaluated, but E4X filter expressions are not supported.

For example, you cannot evaluate myxml.(@id=='3')) .

• You cannot call functions that are defined as a variable.

Use watchpoints

When debugging an application, you can set watchpoints on specific instances of variables to stop execution when the watched variable changes value. Because watchpoints are set on a specific instance of a variable, you cannot set the watchpoint in the code editor. Instead, you set a watchpoint from the Variables view during a debugging session.

When setting watchpoints, keep in mind the following:

• When a debugging session ends, all watchpoints are removed.

• You cannot set watchpoints on getters, but you can set them on the field of a getter.

For example, you cannot set a watchpoint on width , but you can set a watchpoint on _width .

• You cannot set watchpoints on local variables, but you can set watchpoints on members of local variables, as illustrated in the following code fragment.

public class MyClass

{

// These are fields of a class, so you can set a watchpoint on

// 'memberInt', and on 'memberButton', and on 'memberButton._width':

private var memberInt:int = 0;

private var memberButton:Button = new Button();

public function myFunction():void {

// You CANNOT set a watchpoint on 'i', because it is local:

var i:int = 0;

// You CANNOT set a watchpoint on 'someButton', because it is local;

// but you CAN set a watchpoint on 'someButton._width':

var someButton:Button = new Button();

...

}

• Execution stops for a watchpoint when the original value of an object instance changes.

This differs from using an expression in a conditional breakpoint to stop execution whenever a variable changes value.

Set watchpoints

❖ In a debugging session, there are two ways to set a watchpoint:

• In the Variables view, open the context menu for a variable, and select Toggle Watchpoint

• From the Flash Builder Run menu, select Add Watchpoint.

From the Add Watchpoint dialog, select the variable you want to watch.

The Variables view displays a “pencil icon” to indicate that a watchpoint has been set on that variable.

Note: If you attempt to set a watchpoint on a getter, Flash Builder opens a dialog suggesting a valid variable for the watchpoint. If you delete the suggested variable, the dialog lists all valid variables for the object.

Use Run to Line

Flash Builder provides the Run to Line command to break out of a loop during a debugging session.

While debugging, you sometimes find that your code is executing a loop that repeats many times. To break out of this loop, use the Run to Line command, available from the Run menu.

Chapter 6: Profiling Tools in Flash Builder

Adobe Flash Builder Premium contains an additional perspective - the Flash Profiling perspective that helps you identify performance bottlenecks and memory leaks in your applications.

About profiling and how the profiler works

The profiler helps you identify performance bottlenecks and memory leaks in your applications. You launch it from within Adobe Flash Builder, and as you interact with your application, the profiler records data about the state of the application. The recorded data includes the number of objects, the size of those objects, the number of method calls, and the time spent in those method calls.

Profiling an application can help you understand the following about your application:

Call frequency In some cases, computationally expensive methods are called more than once when multiple calls are not necessary. By identifying the most commonly called methods, you can focus your performance-tuning time on a smaller area of the application, where it can have the most impact on performance.

Method duration The profiler can tell you how much time was spent in a particular method. Or, if the method is called multiple times, what the average amount of time spent in that method was during a profiling section. If you discover that some methods cause a performance bottleneck, you can try to optimize those methods.

Call stacks By tracing the call stack of a method, you can see the entire path that the application takes as it calls successive methods. You then sometimes discover that methods are being called unnecessarily.

Number of instances (object allocation) You sometimes discover that the same object is being created many times, when only a specific number of instances are required. In these cases, you can consider implementing a Singleton pattern if you really require only one of those objects. Or you can apply other techniques that reduce excessive object allocation. If the number of objects is large, but necessary, you can consider optimizing the object itself to reduce its aggregate resource and memory usage.

Object size If you notice that some objects are disproportionately large, you can try to optimize those objects to reduce their memory footprint. It is especially helpful if you optimize objects that are created many times in the application.

Garbage collection When comparing profiling snapshots, you sometimes discover that some objects that the application no longer requires are still "loitering", or are still stored in memory. To avoid these memory leaks, you add logic that removes any remaining references to those objects.

Profiling is an iterative process and a part of each step of application development. To quickly identify problem areas and gain the most benefit by profiling, it is recommended that you profile the application early and as often as possible in the development cycle.

How the profiler works

The profiler is an agent that communicates with the application that is running in Flash Player. It connects to your application with a local socket connection. As a result, you might have to disable anti-virus software to use it if your antivirus software prevents socket communication.

120

Last updated 12/3/2012

USING FLASH BUILDER

Profiling Tools in Flash Builder

When the profiler is running, it takes a snapshot of data at short intervals, and records what Adobe Flash Player is doing at the time. This is called sampling. For example, if your application is executing a method at the time of the snapshot, the profiler records the method. If, by the next snapshot, the application is still executing that same method, the profiler continues to record the time. When the profiler takes the next snapshot, and the application has moved on to the next operation, the profiler can report the amount of time it took for the method to execute.

Sampling lets you profile without noticeably slowing down the application. The interval is called the sampling rate, and it occurs every 1 ms or so during the profiling period. This means that not every operation is recorded and that not every snapshot is accurate to fractions of a millisecond. But it does give you a much clearer idea of what operations take longer than others.

By parsing the data from sampling, the profiler can show every operation in your application, and the profiler records the execution time of those operations. The profiler also records memory usage and stack traces and displays the data in a series of views, or panels. Method calls are organized by execution time and number of calls, as well as number of objects created in the method.

The profiler also computes cumulative values of data for you. For example, if you are viewing method statistics, the cumulative data includes the time and memory allocated during that method, plus the time and memory allocated during all methods that were called from that method. You can drill down into subsequent method calls until you find the source of performance problems.

Types of profiling

Before you use the profiler, decide on what profiling you are going to do: performance profiling or memory profiling.

Performance profiling is the process of looking for methods in your application that run slowly and can be improved.

Once identified, these hotspots can be optimized to speed up execution times so that your application runs faster and responds more quickly to user interaction. You generally look for two things when doing performance profiling: a method that is called only once but takes more time to run than similar methods, or a method that may not take much time to run but is called many times. You use the performance profiling data to identify the methods that you then optimize. You might find that reducing the number of calls to a method is more effective than refactoring the code within the method.

Memory profiling is the process of examining how much memory each object or type of object is using in the application. You use the memory profiling data in several ways: to see if there are objects that are larger than necessary, to see if there are too many objects of a single type, and to identify objects that are not garbage collected (memory leaks). By using the memory profiling data, you can try to reduce the size of objects, reduce the number of objects that are created, or allow objects to be garbage collected by removing references to them.

Memory profiling can slow performance of your application because it uses much more memory than performance profiling. Do memory profiling only when necessary.

You often do both performance profiling and memory profiling to locate the source of performance problems. You use performance profiling to identify the methods that result in excessive memory allocation and long execution times.

Then, you use memory profiling to identify the memory leaks in those methods.

When you know what profiling you are going to do, you can start the profiler.

Profiling APIs

The profiler uses the ActionScript APIs defined in the flash.sampler.* package. This package includes the Sample,

StackFrame, NewObjectSample, and DeleteObjectSample classes. You can use the methods and classes in this package to write your own profiler application or to include a subset of profiling functionality in your applications.

In addition to the classes in the flash.sampler.* package, the profiler also uses methods of the System class.

Internal player actions

Typically, the profiler records data about methods of a particular class that Flash Player was executing during the sampling snapshot. However, sometimes the profiler also records internal player actions. These actions are denoted with brackets and include [keyboardEvent] , [mark] , and [sweep] .

For example, if [keyboardEvent] is in the method list with a value of 100, you know that the player was doing some internal action related to that event at least 100 times during your interaction period.

The following table describes the internal Flash Player actions that appear in profiling data:

Action

[generate]

[mark]

[newclass]

[pre-render]

[reap]

[render]

[sweep]

[verify]

[event_typeEvent]

Description

The just-in-time (JIT) compiler generates AS3 machine code.

Flash Player marks live objects for garbage collection.

Flash Player is defining a class. Usually, this occurs at startup but a new class can be loaded at any time.

Flash Player prepares to render objects (including the geometry calculations and display list traversal that happens before rendering).

Flash Player reclaims DRC (deferred reference counting) objects.

Flash Player renders objects in the display list (pixel by pixel).

Flash Player reclaims memory of unmarked objects.

The JIT compiler performs ActionScript 3.0 bytecode verification.

Flash Player dispatches the specified event.

You can use this information to help you identify performance issues. For example, if you see many entries for [mark] and [sweep] , you can assume that there are many objects being created and then marked for garbage collection. By comparing these numbers across different performance profiles, you can see whether changes that you make are effective.

To view data about these internal actions, you view a performance profile in the Performance Profile view or a memory

profile in the Allocation Trace view. For more information, see “ Performance Profile view ” on page 131 and

“ Allocation Trace view ” on page 128.

Additional resources

The profiler alone does not improve the size, speed, and perceived performance of your application. After you use the profiler to identify the problem methods and classes, see the following resources in the Flex documentation for help in improving your application:

• Optimizing applications

• Improving startup performance

122

The Flash Profiling perspective and profiler views

The Profiling perspective displays several panels (or views) that present profiling data in different ways. As you interact with your application, the profiler records data about the state of the application, including the number of objects, the size of those objects, the number of method calls, and the time spent in those method calls.

View information in the Live Objects view

The Live Objects view displays information about the classes that the current application uses. This view shows the classes that are instantiated, how many were created, how many are in memory, and how much memory the active objects are taking up.

The profiler updates the data in the Live Objects view continually while you profile the application. You do not have to refresh the view or keep focus on it to update the data.

To use the Live Objects view, enable memory profiling when you start the profiler. This is the default setting. If you close the Live Objects view and want to reopen it, open the drop-down list in the Profile view and select Watch Live

Objects.

Description

The number of instances of each class that are currently in memory. This value is always smaller than or equal to the value in the Cumulative Instances column.

The total amount of memory, in bytes, that all instances of each class used, including classes that are no longer in memory.

The total amount of memory, in bytes, that all instances of each class currently use. This value is always smaller than or equal to the value in the Cumulative Memory column.

You typically use the data in the Live Objects view to see how much memory the objects use. As objects are garbage collected, the number of instances and memory use decrease, but the cumulative instances and cumulative memory use increase. This view also tells you how memory is used while the application is running.

For more information on running and analyzing the results of garbage collection, see “ Garbage collection ” on page 142.

You limit the data in the Live Objects view by using the profiler filters. For more information, see “ Profiler filters ” on page 136.

Memory Snapshot view

The Memory Snapshot view displays information about the application’s objects and memory usage at a particular time. Unlike the Live Objects view, the data in the Memory Snapshot view is not continually updated.

To use the Memory Snapshot view, enable memory profiling when you start the profiler. This setting is the default.

Create and view a memory snapshot

1 Start a profiling session.

2 Interact with your application until you reach a point in the application’s state where you want to take a memory snapshot.

3 Select the application in the Profile view.

4 Click the Take Memory Snapshot button.

The profiler creates a memory snapshot and marks it with a timestamp. The profiler also implicitly triggers garbage collection before the memory snapshot is recorded.

Description

The classes that had instances in memory at the time that you recorded the memory snapshot.

The package that each class is in. If the class is not in a package, then the value of this field is the filename that the class is in. The number following the dollar sign is a unique ID for that class.

If the Package field is empty, the class is in the global package or the unnamed package.

The number of instances in memory of each class at the time that you recorded the memory snapshot.

The amount of memory, in bytes, that all instances of each class used at the time that you recorded the memory snapshot.

You typically use a memory snapshot as a starting point to determine which classes to focus on for memory optimizations or to find memory leaks. To do so, create multiple memory snapshots at different points in time and then compare the differences in the Loitering Objects or Allocation Trace views.

You can save memory snapshots to compare an application’s state during a different profiling session. For more

information, see “ Save and load profiling data ” on page 140.

When you double-click a row in the Memory Snapshot view, the profiler displays the Object References view. This view displays the stack traces for the current class’s instances. You view the stack traces for the current class’s instances

in the Object References view. For more information about the Object References view, see “ Object References view ” on page 126.

You can also specify which data to display in the Memory Snapshot view by using profiler filters. For more

information, see “ Profiler filters ” on page 136.

Object References view

The Object References view displays stack traces for classes that were instantiated in the application.

The Object References view displays information about the selected class’s instances in a tree view format. The Object

References view also displays paths to the object’s back-references leading up to the GC root. If there is more than one instance of a path to an object reference, the path is not repeated.

To open the Object References view, double-click a class name in the Memory Snapshot or Loitering Objects views.

The Object References view displays data in two tables: the Instances table and the Allocation Trace table.

The Instances table lists all objects that hold references to the current object. The number in parentheses after each class name is represented as a node in the tree view. The number denotes the number of paths leading to the GC root from that node.

You cannot view the number of forward references for an object. An object without references is not listed in this table.

You can only view data in this table when you enable allocation traces when you start the profiler.

You can open the source code of the selected class by double-clicking a class in this table.

Allocation Trace view

The Allocation Trace view shows which methods were called between two memory snapshots and how much memory was consumed during those method calls. To open the Allocation Trace view, you select two memory snapshots, and

then click the View Allocation Trace button. For information on recording a memory snapshot, see “ Memory

Snapshot view ” on page 125.

The result of the memory snapshot comparison is a list of methods that Flash Player executed between the two memory snapshots. For each of these methods, the profiler reports the number of objects created in that method.

You can use this information to optimize performance. After you identify methods that create an excessive number of objects, you can optimize those hotspots.

To use the Allocation Trace view, enable allocation traces when you start the profiler. The default is disabled.

Performance Profile view

The Performance Profile view is the primary view to use when doing performance profiling. It shows statistics such as number of calls, self-time, and cumulative time for the methods that are called during a particular sampling interval.

You use this data to identify performance bottlenecks.

The process of performance profiling stores a list of methods and information about those methods that were called between the time you clear the performance data and the time you capture new data. This time difference is known as the interaction period.

To use the Performance Profile view, enable performance profiling when you start the profiler. This is the default setting.

Generate a performance profile

1 Start a profiling session with performance profiling enabled.

2 Interact with your application until you reach the point where you want to start profiling.

3 Click the Reset Performance Data button.

Identify method performance characteristics

The Method Statistics view shows the performance characteristics of the selected method. You typically use the

Method Statistics view to identify performance bottlenecks in your application. By viewing, for example, the execution times of a method, you can see which methods take a disproportionate amount of time to run. Then you can selectively optimize those methods.

For more information, see “ Performance Profile view ” on page 131.

1 Double-click a row in the Performance Profile view or select a method in the Performance Profile view.

2 Click the Open Method Statistics button.

There are three sections in the view:

• A summary of the selected method’s performance, including the number of calls, cumulative time, and self-time.

• Callers table: Details about the methods that called the selected method. In some situations, it is important to know if the selected method is being called excessively, how it is being used, and whether it is being used correctly.

• Callees table: Details about the methods that were called by the selected method.

The amount of time, in milliseconds, that each called method spent executing. This does not include methods called by subsequent methods.

You can navigate the call stack while you attempt to find the performance bottlenecks by clicking the methods in either the Callers or Callees tables. If you double-click a method in these tables, the profiler displays that method’s summary at the top of the Method Statistics view and then shows the callers and callees for the newly selected method in the two tables.

Note: The cumulative time minus the self-time in this view will not always equal the cumulative time of the callers. That is because if you drill up to a caller, then the cumulative time will be the self-time of that caller plus all chains from which the original method was called, but not other callees.

You can also use the Back, Forward, and Home profiler buttons to navigate the call stack.

You can limit the data in the Method Statistics view by using the profiler filters. For more information, see “ Profiler filters ” on page 136.

Loitering Objects view

The Loitering Objects view shows you the differences between two memory snapshots of the application that you are profiling. The differences that this view shows are the number of instances of objects in memory and the amount of memory that those objects use. This is useful in identifying memory leaks. The time between two memory snapshots is known as the snapshot interval.

To open the Loitering Objects view, select two memory snapshots and click the Loitering Objects button. For

information on recording a memory snapshot, see “ Memory Snapshot view ” on page 125.

If the Package field is empty, the object is in the global package or the unnamed package.

The number of instances created during the snapshot interval. This is the difference between the number of instances of each class that existed in the first snapshot and the number of instances of each class in the second snapshot.

For example, if there were 22,567 strings in the first snapshot, and 22,861 strings in the second snapshot, the value of this field would be 294.

The amount of memory allocated during the snapshot interval. This is the difference between the amount of memory that the instances of each class used at the time the first snapshot was taken and the amount of memory that the instances of each class used at the time the second snapshot was taken.

For example, if Strings took up 2,031,053 bytes in the first snapshot and 2,029,899 bytes in the second snapshot, the value of this field would be 1154 bytes.

For more information on identifying memory leaks, see “ Locate memory leaks ” on page 143.

Memory Usage graph

The Memory Usage graph shows you the memory used by the application that you are profiling. This value is different from the memory usage of Flash Player and its browser. That is because this value does not include the profiler agent or the browser’s memory usage. It consists only of the sum of the profiled application’s live objects. As a result, if you compare the value of memory usage in this graph against the amount of memory the browser uses as shown in, for example, the Windows Task Manager, you get different results.

The following image shows the graph in the Memory Usage view:

135

The value for Current Memory is the same as the sum of the totals in the Live Objects view’s Memory column, assuming that all filters are disabled.

The value for Peak Memory is the highest amount of memory that this application has used during the current profiling session.

The Memory Usage graph shows the application’s memory for the last 100 seconds. You cannot configure this number, and you cannot save historical data for the chart.

If you close the Memory Usage graph and want to reopen it, click the drop-down list in the Profile view and select

Profiler filters

The amount of data in a profiler view can sometimes be overwhelming and the level of detail can be too great. The internal actions of Flash Player might obscure the data that you are truly interested in, such as your own methods and classes. Also, Flash Player creates and destroys many objects without your direct interaction. Thus, you could see that thousands of strings or arrays are being used in your application.

You can set filters in the following views:

• Live Objects

• Memory Snapshot

• Performance Profile

• Method Statistics

• Allocation Trace

You can define which packages appear in the profiler views by using the profiler filters. There are two types of filters:

Exclusion filters The exclusion filters instruct the profiler to exclude from the profiler views packages that match the patterns in its pattern list. If you use charting controls, for example, but do not want to profile them, you can add the mx.charts.* pattern to the exclusion filter. You can also exclude global built-in items. These include global classes such as String and Array.

Inclusion filters The inclusion filters instruct the profiler to include in the profiler views only those packages that match the patterns in its pattern list. If you have a custom package named com.mycompany.*, for example, you can view details about only classes in this package by adding it to the inclusion filter.

The default exclusions are flash.*.*, spark.*.*, mx.*.*, and the Flex framework classes in the global or unnamed package.

These include global classes such as String and Array. This means that the default inclusions are user-defined classes in the unnamed package and user-defined classes in nonframework packages (such as com.mycompany.MyClass).

You can exclude user-defined classes that are in the unnamed package from the profiling data. To do this, add “*” to the exclusion list.

Maximum visible rows Maximum visible rows sets the number of rows of data that can be displayed in a view. Increase this value if the data you are looking for is not displayed in the view. Decrease this value to improve performance of the profiler. Use other filters to ensure that you are displaying the data of interest to you.

Maximum back-reference paths to find: Maximum back-reference paths sets the number of paths to a referenced object to display when examining object references. The paths are displayed according to the shortest path. By default, the ten shortest paths are displayed. Increase this value to display additional paths or select Show All Back-Reference

Paths. Showing additional paths can help you locate objects that are no longer referenced. See “ Locate memory leaks ” on page 143.

Set default filter preferences

❖ Open the Preferences dialog and select Flash Builder > Profiler > Inclusion Filters or Exclusion Filters.

When displaying profiler data, the profiler applies the exclusion filters first; then it applies the inclusion filters. For example, suppose you set the exclusion filter to mx.controls.*, but set the inclusion filter to mx.*.*; the profiler does not show details about any classes in the mx.controls package because that package was excluded, even though their pattern matches the inclusion pattern list. Similarly, suppose you set the exclusion filter to mx.*.* and the inclusion filter to mx.controls.*; the profiler does not show details about any classes in mx.controls.* package because they were excluded before it was included.

When you filter out certain data points, the percentage values of columns are adjusted to reflect only the percentage of non-filtered data.

Using the Flash Builder profiler

The profiler requires Flash Player version 9.0.124 or later. You can profile applications that were compiled for Flex 2,

Flex 2.0.1, and Flex 3. You can use the profiler to profile ActionScript 3.0 applications that were built with Flash

Authoring, as well as desktop applications that run on Adobe AIR.

The profiler requires debugging information in the application that you are profiling. When you compile an application and launch the profiler, Flash Builder includes the debugging information in the application by default.

You can explicitly include debugging information in an application by setting the debug compiler option to true . If you export an application by using the Export Release Build option, the application does not contain debugging information in it.

Profile external applications

In addition to profiling applications that you are developing in Flash Builder, you can profile external applications.

External applications can be SWF files located anywhere that is accessible. This includes applications that are located on a remote web server or an application that is on your local file system.

For the SWF file, you can specify either a URL or a file system location. If you specify a URL, Flash Builder launches the application’s SWF file within the default browser. The browser must be using the debugger version of Flash Player to successfully profile the application.

If you specify a file system location for the SWF file, Flash Builder opens the application within the debugger version of the stand-alone Flash Player. In general, use a URL to request the file. Running applications in the stand-alone version of Flash Player can produce unexpected results, especially if your application uses remote services or network calls.

5 Click the Launch button. If you specified a URL for the location of the application, Flash Builder launches the application within the default browser. If you specified a file system location for the application, Flash Builder opens the application in the stand-alone version of Flash Player.

If you specified a SWF file that was not compiled with debugging information, Flash Builder returns an error.

Recompile the application with the debug compiler option set to true and launch it again.

Garbage collection

Garbage collection is the act of removing objects that are no longer needed from memory. Memory used by instances that no longer have any references to them should be deallocated during this process.

Flash Player performs garbage collection as necessary during an application’s life cycle. Unreferencing an object does not trigger garbage collection. So, when you remove all references to an object, the garbage collector does not necessarily deallocate the memory for that object. That object becomes a candidate for garbage collection.

Clicking the Run Garbage Collector button does not guarantee that all objects that are eligible for garbage collection are garbage collected. Garbage collection is typically triggered by the allocation of memory for new resources. When new resources require memory that is not available in the current allocation, the garbage collector runs and frees up memory that has been marked for deallocation. As a result, even if you remove all references to it, it might not be immediately garbage collected, but likely will be garbage collected when other instances are created and used. If an application is idle, you can watch its memory allocation. Even though there can be objects that are marked for collection, an idle application’s memory usage typically does not change until you start interacting with it.

Flash Player allocates memory in blocks of many bytes, and not one byte at a time. If part of a block has been marked for garbage collection, but other parts of the block have not been marked, the block is not freed. The garbage collector attempts to combine unused portions of memory blocks into larger blocks that can be freed, but this is not guaranteed to occur in every pass of the garbage collector.

Garbage collection occurs implicitly before memory snapshots are recorded. In other words, clicking the Take

Memory Snapshot button is the equivalent of clicking the Run Garbage Collector button and then clicking the Take

Memory Snapshot button.

Run garbage collection while profiling your application

❖ Select the application in the Profile view, and click the Run Garbage Collector button.

You analyze the garbage collector’s effectiveness by comparing two memory snapshots before and after garbage collection occurs.

Identify problem areas

You can use various techniques to identify problem areas in your applications by using the profiler.

Locate memory leaks

One of the most common problems you face in application development is memory leaks. Memory leaks often take the form of objects that were created within a period but not garbage collected.

One way to identify memory leaks is to look at the number of references to an object in the Instances table in the Object

References view. You can generally ignore references from document properties and bindings, and look for unexpected or unusual references, especially objects that are not children of the object. For more information, see

“ Object References view ” on page 126.

You can also examine paths to instances of an object to determine if a path has a back-reference to the garbage collector

(GC Root). An instance that was expected to be released, but has references to GC Root, indicates a memory leak. In these cases, modify your application code so references to GC Root are removed. An instance that has no references to GC Root is ready for garbage collection. Flash Player eventually frees this memory.

Another way to locate memory leaks is to compare two memory snapshots in the Loitering Objects view to determine which objects are still in memory after a particular series of events.

Common ways to clean up memory links are to use the disconnect() , clearInterval() , and removeEventListener() methods.

Find a back-reference to GC Root for an instance

1 Create a memory snapshot.

See “ Create and view a memory snapshot ” on page 125.

2 Specify the number of back-reference paths to find.

From the Memory Snapshot view, specify the maximum number of paths to find, or select Show All Back-Reference

Paths.

3 Double-click a class in the memory snapshot to open the Object Reference view.

4 Expand the listed paths to and examine if there is a back-reference to GC Root.

Find loitering objects

1 Create two memory snapshots.

See “ Create and view a memory snapshot ” on page 125.

2 Select the two memory snapshots to compare.

Note: If you have more than two memory snapshots, you cannot select a third one. You can compare only two memory snapshots at one time.

3 Click the Find Loitering Objects button.

143

Last updated 12/3/2012

USING FLASH BUILDER

Profiling Tools in Flash Builder

Loitering Objects view shows you potential memory leaks. The Instances and Memory columns show the differences between the number of instances of a class and the amount of memory consumed by those instances during the interval between one snapshot and the next. If you see a class that you did not expect to be created during that time, or a class that you expected to be destroyed during that time, investigate your application to see if it is the source of a memory leak.

4 To determine how an object in the Find Loitering Objects view was instantiated, double-click the object in the view.

The Object References view shows you the stack trace for each instance that you selected.

One approach to identifying a memory leak is to first find a discrete set of steps that you can do over and over again with your application, where memory usage continues to grow. It is important to do that set of steps at least once in your application before taking the initial memory snapshot so that any cached objects or other instances are included in that snapshot.

Then you perform that set of steps in your application a particular number of times—3, 7, or some other prime number—and take the second memory snapshot to compare with the initial snapshot. In the Find Loitering Objects view, you might find loitering objects that have a multiple of 3 or 7 instances. Those objects are probably leaked objects.

You double-click the classes to see the stack traces for each of the instances.

Another approach is to repeat the sequence of steps over a long period and wait until the memory usage reaches a maximum. If it does not increase after that, there is no memory leak for that set of steps.

Common sources of memory leaks include lingering event listeners. You can use the removeEventListener() method to remove event listeners that are no longer used. For more information, see Object creation and destruction in Using Flex 4.6

.

Analyze execution times

By analyzing the execution times of methods and the amount of memory allocated during those method calls, you can determine where performance bottlenecks occur.

This is especially useful if you can identify the execution time of methods that are called many times, rather than methods that are rarely called.

Determine frequency of method calls

1 Start a profiling session and ensure that you enable performance profiling when configuring the profiler on the startup screen.

2 Select your application in the Profile view.

3 Interact with your application until you reach the point where you want to start analyzing the number of method calls. To see how many times a method was called from when the application started up, do not interact with the application.

4 Click the Reset Performance Data button. This clears all performance data so that the next performance profile includes any data from only this point forward.

5 Interact with your application until you reach the point where you check the number of method calls since you reset the performance data.

6 Click the Capture Performance Profile button.

7 Double-click the performance profile in the Profile view.

8 In the Performance Profile view, sort the data by the Method column and find your method in the list.

The value in the Calls column is the number of times that method was called during this sampling interval. This is the time between when you clicked the Reset Performance Data button and when you clicked the Capture

Performance Profile button.

Last updated 12/3/2012

144

USING FLASH BUILDER

Profiling Tools in Flash Builder

Examine the values in the Cumulative Time, Self Time, Avg. Cumulative Time, and Avg. Self Time columns of the

Performance Profile view. These show you the execution time of the methods.

Compare the time each method takes to execute against the time that all the methods that are called by a particular method take to execute. In general, if a method’s self-time or average self-time are high, or high compared to other methods, look more closely at how the method is implemented and try to reduce the execution time.

Similarly, if a method’s self-time or average self-time are low, but the cumulative time or average cumulative time are high, look at the methods that this method calls to find the bottlenecks.

Locate excessive object allocation

One way to identify trouble areas in an application is to find out where you might be creating an excessive number of objects. Creating an instance of an object can be an expensive operation, especially if that object is in the display list.

Adding an object to the display list can result in many calls to style and layout methods, which can slow down an application. In some cases, you can refactor your code to reduce the number of objects created.

After you determine whether there are objects that are being created unnecessarily, decide whether it is reasonable or worthwhile to reduce the number of instances of that class. For example, you could find out how large the objects are, because larger objects generally have the greatest potential to be optimized.

To find out which objects are being created in large numbers, you compare memory snapshots of the application at two points in time.

View the number of instances of a specific class

1 Start a profiling session and ensure that you enable memory profiling when configuring the profiler on the startup screen.

2 Interact with your application until you reach the place to take a memory snapshot.

3 Click the Take Memory Snapshot button. The profiler adds a new memory snapshot to the application list in the

Profile view.

4 Open the memory snapshot by double-clicking it in the Profile view.

5 To view the number of instances of a particular class, and how much memory those instances use, sort by the Class column and find your class in that column. You can also sort by the other columns to quickly identify the objects that take up the most memory or the objects with the most instances. In most cases, Strings are the class with the most instances and the most memory usage.

For more information about the Memory Snapshot view, see “ Memory Snapshot view ” on page 125.

Locate instances of excessive object allocation

1 Start a profiling session and ensure that you enable memory profiling when configuring the profiler on the startup screen.

2 Interact with your application until you reach the first place to take a memory snapshot.

3 Click the Take Memory Snapshot button.

The profiler saves the memory snapshot in the Profile view, and marks the snapshot with a timestamp.

4 Interact with your application until you reach the second place to take a memory snapshot.

5 Click the Take Memory Snapshot button again.

The profiler saves the second memory snapshot in the Profile view, and marks the snapshot with a timestamp.

Using Adobe Scout with Flash Builder

Adobe® Scout (formerly codenamed Project "Monocle") is a memory profiling tool to profile ActionScript applications

(Flash Player on the desktop) and mobile applications that run on Adobe AIR.

Adobe Scout uses the Telemetry feature to help you profile your Flash content. Adobe Scout provides many of the advanced telemetry options that you can use while profiling your application. For example, the remote profiling feature in Adobe Scout lets you run the content to profile on a different computer or device than the computer that is running Adobe Scout.

To understand more about Adobe Scout and the Telemetry feature, see www.adobe.com/go/learn_telemetry_en .

Difference between Adobe Scout and the Flash Builder profiler

To use the Flash Builder profiler, you need a debugger version of Flash Player. The Flash Builder profiler lets you identify performance bottlenecks and memory leaks at an ActionScript-level inside the debugger version of Flash player.

Adobe Scout is based on the Telemetry feature, which runs on the release version of Flash Player. Telemetry works inside the internals of the Flash runtime, beyond the ActionScript level, and sends data to Adobe Scout. Adobe Scout then parses the data and displays it clearly and concisely.

You do not need the debugger version of Flash Player to use Adobe Scout; you can profile your content even in a release version of the build. This feature is especially helpful in tracking down a memory leak or fine-tuning the performance of a released application.

Configure Adobe Scout with Flash Builder

Before you configure Adobe Scout with Flash Builder, ensure that you’ve installed:

• Flash Player 11.3 or a higher version (stand-alone or plug-in) and Adobe AIR 3.3 or a higher version

• Adobe Scout

To enable Telemetry in Flash Player and Adobe AIR, you edit the Flash Player Configuration file (telemetry.cfg).

For more information on installing Adobe Scout and editing the configuration file, see www.adobe.com/go/learn_telemetry_en .

Enable advanced Telemetry in Flash Builder

Important: The advanced telemetry options are available only for ActionScript projects and ActionScript Mobile projects that use the ActionScript Compiler 2.0 (ASC 2.0).

You can enable advanced telemetry while debugging or testing your application.

To use the advanced telemetry features in Flash Builder, follow these steps:

1 In the Project Properties dialog of your ActionScript project, select ActionScript Compiler.

Last updated 12/3/2012

USING FLASH BUILDER

Profiling Tools in Flash Builder

2 Under Telemetry Options, select Enable Detailed Telemetry.

When you select this option, Flash Builder adds the -advanced-telemetry argument to the compiler and updates the compiler settings.

Protect advanced telemetry data for a released application

You can protect your advanced telemetry data by using a password, if necessary. When you export a release version of your application, you can specify a password to ensure authenticated access to your telemetry data.

You can specify a password by following these steps:

1 In the Export Release Build wizard, ensure that Enable Detailed Telemetry is selected.

2 Enter a password, and confirm it.

Note: The password is applicable only for the current session. If you change the password, you need to recompile the

SWF file.

Turn off -sampler value for iOS applications

Sampler is an important feature in advanced telemetry. Once you enable advanced telemetry for your project, the sampler parameter value is set by default.

For iOS applications, turning on the -sampler option can cause the application to have some performance issues. If you do not want to connect to Adobe Scout and view the telemetry data, Flash Builder lets you turn off the -sampler value.

To turn off the -sampler value in Flash Builder, follow these steps:

1 Click Customize Launch in the Run/Debug configurations dialog box or Export Release Build dialog box.

2 In the Customize Launch Parameters dialog, click X next to the -sampler parameter name.

3 Click OK. Under Modified Parameters, the value of the -sample parameter appears as <value not set> .

FlexUnit test environment

The FlexUnit test environment allows you to generate and edit repeatable tests that can be run from scripts or directly within Flash Builder. Flash Builder supports both FlexUnit 4 and Flex Unit 1 open source frameworks.

From Flash Builder, you can do the following:

• Create unit test cases and unit test suites

Flash Builder wizards guide you through the creation of test cases and test suites, generating stub code for the tests.

• Run the test cases and test suites

You can run test cases and test suites various ways from within Flash Builder or outside the Flash Builder environment. The results of the tests are displayed in a test application. Flash Builder opens a Flex Unit Results

View for analysis of the test run.

• Navigate to source code from the Flex Unit Results View

In the Test Results panel, double-click a test to open the test implementation.

The Test Failure Details panel lists the source and line number of the failure. If the listed source is in the current workspace, double-click the source to go directly to the failure.

To understand the basics of Test Driven Development (TDD) using FlexUnit and Flash Builder, see this Adobe

Dev Center article by Adobe Community Professional, Elad Elrom.

Create FlexUnit tests

You can create FlexUnit test case classes and test case suites for the following types of projects:

• Flex project

• Flex Mobile project

• Flex Library project

• ActionScript project

• Adobe AIR project

When creating a test case class, you can specify the following options:

• A src folder in a Flex project for the class

• A package for the class

• The classes to test

• Methods to test for each specified class

A FlexUnit test case suite is a series of tests based on previously created test case classes, specified methods in those classes, and other test case suites.

If you select an ActionScript class file in project, then that class is automatically selected for the FlexUnit test case in the New Test Case Class wizard.

2 In the New Test Case Class wizard, specify whether to create a class in the FlexUnit 4 style or FlexUnit 1 style.

3 Specify a name for the test case class.

4 (Optional) Specify a source folder and package for the test case class, or accept the defaults.

The default source folder is the src folder of the current project. The default package is flexUnitTests , which is at the top level of the default package structure for the project.

5 (Optional) Enable the Select Class to Test toggle, and browse to a specific class. Click Next.

6 (Optional) Select the methods in the selected class that you want to test.

7 Click Finish.

Code the test case you created. Use the generated code stubs as a starting point.

Create a FlexUnit test case suite

This procedure assumes that you have previously created test case classes.

2 In the New Test Suite Class wizard, specify whether to create a class in the FlexUnit 4 style or FlexUnit 1 style.

3 Provide a name for the test suite.

4 Navigate in the test suites and test cases to select the classes and methods to include in the test suite. Click Finish.

Customize default FlexUnit test case classes and test case suite classes

You can customize the default FlexUnit test case classes and test case suite classes that Flash Builder creates. Flash

Builder uses file templates to create the default versions of these files.

The file templates for FlexUnit are available from the Preferences dialog at Flash builder > FlexUnit.

There are separate templates for FlexUnit1 and FlexUnit4 test case classes and test suite classes.

See “ Customize file templates ” on page 44 for information on how to modify the default file templates.

Note:

FlexUnitCompilerApplication.mxml

and FlexUnitApplication.mxml derive from the template for MXML

Web Application or MXML Desktop Application. The template that is used depends on whether the Flex project is

configured for a web application (runs in Adobe® Flash® Player) or a desktop application (runs in Adobe AIR).

Build user interfaces

You can build your user interface in Flash Builder using Flex components. You can also extend components to add new properties and methods, and create components as required by your application.

For example, you can create rich form experiences using the Spark Form. The Spark Form is a highly customizable container that supports multiple form designs. You can use the Flex Charting components to create some of the most common chart types, and also give you extensive control over the appearance of your charts.

For more information on using Flex components to build user interfaces, see Building the user interface.

Use themes

Flash Builder provides several themes that help you implement a more personalized appearance to your applications.

Themes provided by Flash Builder include a set of Spark themes and a set of Halo themes. The default theme for Flex

4.x components is Spark. Halo is the default theme for Flex 3. You can import additional themes or create your own themes.

For more information on theme support in Flex, see About themes.

The name of the theme is determined by the name element in the metadata.xml

file contained within the theme folder. If the name element is not specified, or if metadata.xml is not present, then the name of the theme folder becomes the name of the theme.

Flash Builder themes can be in the following formats:

• Theme ZIP file

Extract the contents of the ZIP file before importing the theme. The extracted contents should contain all required files.

• CSS or SWC file for a theme

The CSS or SWC file must be in a folder containing all required files for a Flex theme. When you import a theme using Flash Builder, you select either the CSS or SWC file for the theme.

• MXP file

You can use Adobe Extension Manager CS5 to package files for Flex themes in an MXP file. The theme can then be imported into Flash Builder using the Adobe Extension Manager.

For more information on packaging themes in an MXP file, see “ Create an extension file (MXP file) for a Flex theme ” on page 159.

Import Flex themes using Flash Builder

1 From the Flash Builder menu, select Project > Properties > Flex Theme to open the Select Project Theme dialog.

2 Select Import Theme, navigate to the folder containing the theme to import, select the CSS or SWC file, and click OK.

Import Flex themes packaged in an MXP file

1 If you have not already done so, import Adobe Flash® Builder™ 4.7 into Adobe Extension Manager CS6:

2 Open Adobe Extension Manager and select Flash Builder 4.7.

3

After you accept the license, Adobe Extension Manager installs the theme into Flash Builder. The theme is now available in Flash Builder from the Select Project Theme dialog.

Note: You can also double-click the MXP file to start Adobe Extension Manager, which then automatically installs the theme.

Download themes

You can download themes that can then be imported into Flash Builder.

Download Flex themes

1 From the Flash Builder menu, select Project > Properties > Flex Theme to open the Select Project Theme dialog:

2 Select Find More Themes.

Flash Builder opens your default web browser to a page containing themes to download. You can also navigate to any other site containing themes for Flex that you can download.

Create themes

You can create your own themes and import them into Flash Builder. A Flex theme typically contains the following files:

• SWC, SWF file, CSS, PNG, JPEG, and other files that make up your theme.

The files that make up the theme can vary, but must include a SWC file or CSS file.

• preview.jpg

file

The preview image file for the theme. If your theme folder does not contain preview.jpg

, then Flash Builder uses a default preview image for the theme.

• metadata.xml

file

Contains information about the theme, including which versions of the SDK the theme is compatible with. If your theme folder does not contain this file, then Flash Builder creates one when importing the theme.

Typically you package a theme in ZIP file, but ensure that you extract the ZIP file before you can import the theme into

Flash Builder. You can also package the theme files in an Adobe Extension Manager file (MXP file), and use Adobe

Extension Manager to import the theme into Flash Builder.

For more information, see About themes.

Metadata.xml file

The following table lists the elements that can be included in metadata.xml

.

Element Name

Name

Category sdks minVersionInclusive maxVersionExclusive mainFile

Description

The name of the theme that appears in Flash Builder.

When importing a theme using Flash Builder, you can override the name specified in the metadata.xml

file.

Author of the theme. The category under which the theme is displayed in Flash Builder.

Specifies the Flex SDK versions for which the theme is compatible. This element is a parent element for minVersionInclusive and maxVersionExclusive.

If the sdks element is absent, then the theme is valid for all SDKs.

Earliest Flex SDK version for which this theme is compatible. If absent, then this theme is compatible with all earlier versions of the Flex SDK.

Latest SDK version for which this theme is compatible. If absent, then this theme is compatible with all later versions of the Flex SDK.

Top-level file for implementing the theme. This file can reference other files in the theme. For example, a CSS file could reference a SWC file or SWF file.

The -theme compiler argument references the specified file.

The following example shows a typical metadata.xml

According to the metadata.xml

file, the theme is compatible with the Flex 2.0.1 SDK. It is also compatible with SDKs up to, but not including, Flex 4.0.0. When this theme is selected, WindowsLookAlike.css

is the file that is added to the -themes compiler argument.

Create an extension file (MXP file) for a Flex theme

You can use Adobe Extension Manager to create an extension file (MXP file) for a Flex theme. The MXP file can be imported into Flash Builder using Adobe Extension Manager.

Place all your theme files in a staging folder, and then create an extension installation file (MXI file) that the Adobe

Extension Manager uses to create the MXP file. For information on the format of an MXI file, see the Extension File

Format document.

When creating the MXI file, you specify destination paths for each of the theme’s files. The destination paths are in this format:

$flexbuilder/<Theme Name>

• $flexbuilder is defined in the Flash Builder configuration file, XManConfig.xml

. Adobe Extension Manager expands $flexbuilder according to this definition. XManConfig.xml

is at the following location on your file system:

/<Install Dir>/Flash Builder 4/configuration/XManConfig.xml

• <Theme Name> is the name of the folder that contains the Flex theme.

Create an MXP Extension file for a Flex theme

1 Place all the files for the theme, including the MXI file, in a staging folder.

2

3 Navigate to the extension installation file and select it.

4 Navigate to a location for the package file, and name it using the extension .mxp.

You can then test the extension file by installing it using the Adobe Extension Manager.

Add additional themes

You can specify more than one theme file to apply to an application. If there are no overlapping styles, both themes are applied completely. There are other considerations when adding additional themes, such as the ordering of the theme files.

To add additional themes, use the command line compiler, mxmlc with the theme compiler option to specify the path to the theme files.

Using themes provides details on specifying compiler arguments and the ordering of theme files.

Using styles

Styles affect the appearance of an application by specifying values for visual parameters for application components.

You can set styles that apply to all components in an application, to individual components, or to a set of components referenced by a style selector.

For example, you can specify styles such as:

• Text

Font family, size, weight, color, font (bold, italic, underline) and other text display settings

• Border

Thickness, color, rollover color, border-style (solid, inset, outset, none), corner radius, and others

• Color

Fill color and alpha

Note: The styles available for a component varies, according to the component.

You set style properties inline on an MXML tag or separately using CSS code. The CSS code can be inside <fx:Style> tags in an application or in a separate CSS file.

When you apply inline styles to components, you can convert component styles into a CSS rule in an external style sheet. You can use the CSS editor to edit CSS files.

Apply an external or embedded style to an application

You can embed CSS styles in an MXML application file or reference an external CSS file. The following example shows

CSS code to apply styles to all Spark Button components in an application. It also creates a selector, .

myStyle , that can be applied to any component:

@namespace s "library://ns.adobe.com/flex/spark";

@namespace mx "library://ns.adobe.com/flex/mx";

<s:Button { fontSize: 16pt; color: Red } /* type selector */

.myStyle { color: Red } /* class selector */ />

For styles applied to components, such as s:Button , the selector for components must specify a namespace. In this example, s:Button defines a style that is automatically applied to all Spark Button components.

Use the CSS period notation to create a selector that can be applied to any component. In this example, .myStyle

does not have to declare a namespace and can be applied to any component.

Flex has specific requirements for creating and applying styles. For details, see Using styles in Flex.

Create CSS files

Use the New CSS File wizard to create CSS files for a project. The New CSS File wizard creates a blank file that you can use to define your CSS styles.

By default, Flash Builder adds the default namespaces for Spark and MX styles.

To create a blank CSS file:

2 Specify a source folder.

The source folder can be in the current project or another project.

3 Specify a package for the file

Select from the packages available in the project. If you want to place the file in a new package, then first create the

5 Click Finish.

Flash Builder uses templates that define the contents of newly created files. You can customize the templates that Flash

Builder uses. See “ Customize file templates ” on page 44.

Use the CSS editor

Flash Builder provides a CSS editor which you can use to create and edit style sheets for your application. The CSS editor is available only in Source mode.

When you create a style sheet in Flash Builder, Flash Builder provides the following declarations for the Spark and MX namespaces:

@namespace s "library://ns.adobe.com/flex/spark";

@namespace mx "library://ns.adobe.com/flex/mx";

Some Spark and MX components share the same local name. For example, there is a Spark Button component (in the spark.components.* package) and an MX Button component (in the mx.controls.* package). To distinguish between different components that share the same name, you specify namespaces in your CSS that apply to types.

If you do not use type selectors in your style sheets, then you are not required to declare namespaces. For more information, including examples, see About namespaces in CSS.

Note: Styles are handled differently for applications that use the Flex 3 SDK. If you are working in a Flex project that specifies the Flex 3 SDK, the CSS editor reverts to behavior implemented with Flex Builder 3. See the Flex Builder 3 documentation for information on using the CSS editor for applications that use the Flex 3 SDK.

Add View states and transitions

You can use Flash Builder to create applications that change their appearance depending on tasks performed by the user. For example, the base state of the application could be the home page and include a logo, sidebar, and welcome content. When the user clicks a button in the sidebar, the application dynamically changes its appearance (its state), replacing the main content area with a purchase order form but leaving the logo and sidebar in place.

In Flex, you can add this interaction with view states and transitions. A view state is one of several views that you define for an application or a custom component. A transition is one or more effects grouped together to play when a view state changes. The purpose of a transition is to smooth the visual change from one state to the next.

Support for Flex 3 view states

Flash Builder provides support for view states as implemented in Flex 3. If you create a project that uses the Flex 3 SDK, the MXML editor reverts to the Flex Builder 3 implementation. For information on editing states for the Flex 3 SDK, see the Flex Builder 3 documentation .

Create and edit view states

The MXML editor in Flash Builder contains several features to help you edit source code for view states.

The includeIn and excludeFrom properties for MXML components specify the view state or state group in which a component appears. Code hinting in the MXML editor assists you in selecting a view state or state group for these properties.

You can also use dot notation with component attributes to specify a view state in which the attribute applies. For example, if you want a Button component to appear in two view states, but also have the label change according to the view state, use the dot operator with the label property. Code hinting in the MXML editor assists you in selecting the view state. For example:

<s:Button label.State1="Button in State 1" label.State2="Same Button in State 2">

For more information on creating and editing view states, see Create and apply view states.

Switch view states at runtime

When your application is running, users need to switch from one view state to another. You can define event handlers for user controls so that users can switch states at runtime.

The simplest method is to assign the currentState property to the click event of a control such as a button or a link.

The currentState property takes the name of the view state you want to display when the click event occurs. In the code, you specify the currentState property as follows: click="currentState='viewstatename'"

If the view state is defined for a specific component, you must also specify the component name, as follows: click="currentState='componentID.viewstatename'"

For more information, see View states.

Create view state groups

Flex provides support for view state groups. The stateGroups attribute of the <States> tag lets you group one or more states together. For example, if multiple components appear in the same set of view states, you can create a view state group that contains all these view states. Then, when you set the currentState property to any view state in the group, the components appears. For more information, with examples, see Defining view state groups.

Flash Builder provides code hinting to assist you in creating and editing state groups.

Create a transition

When you change the view states in your application, the components appear to jump from one view state to the next.

You can make the change visually smoother for users by using transitions.

A transition is one or more effects grouped together to play when a view state changes. For example, you can define a transition that uses a Resize effect to gradually minimize a component in the original view state, and a Fade effect to gradually display a component in the new view state.

1 Make sure that you create at least one view state in addition to the base state.

2 In the MXML editor, define a Transition object by writing a <s:transitions> tag and then a <s:Transition> child tag, as shown in the following example:

<s:transitions>

<mx:Transition id="myTransition">

</mx:Transition>

</s:transitions>

To define multiple transitions, insert additional <s:Transition> child tags in the <s:transitions> tag.

3 In the <s:Transition> tag, define the change in view state that triggers the transition by setting the tag’s fromState and toState properties, as in the following example (in bold):

<s:transitions>

<mx:Transition id="myTransition" fromState="*" toState="checkout">

</mx:Transition>

</s:transitions>

In the example, you specify that you want the transition to be performed when the application changes from any view state ( fromState="*" ) to the view state called checkout ( toState="checkout" ). The value "*" is a wildcard character specifying any view state.

4 In the <mx:Transition> tag, specify whether you want the effects to play in parallel or in sequence by writing a

<mx:Parallel> or <mx:Sequence> child tag, as in the following example (in bold):

162

Last updated 12/3/2012

USING FLASH BUILDER

Develop Web and Desktop Applications in Flash Builder

<mx:Transition id="myTransition" fromState="*" toState="checkout">

<mx:Parallel>

</mx:Parallel>

</mx:Transition>

If you want the effects to play simultaneously, use the <mx:Parallel> tag. If you want them to play one after the other, use the <mx:Sequence> tag.

5 In the <mx:Parallel> or <mx:Sequence> tag, specify the targeted component or components for the transition by setting the property called target (for one target component) or targets (for more than one target component) to the ID of the target component or components, as shown in the following example:

<mx:Parallel targets="{[myVGroup1,myVGroup2,myVGroup3]}">

</mx:Parallel>

In this example, three VGroup containers are targeted. The targets property takes an array of IDs.

6 In the <mx:Parallel> or <mx:Sequence> tag, specify the effects to play when the view state changes by writing effect child tags, as shown in the following example (in bold):

<mx:Parallel targets="{[myVBox1,myVBox2,myVBox3]}">

<mx:Move duration="400"/>

<mx:Resize duration="400"/>

</mx:Parallel>

For a list of possible effects and how to set their properties, see Introduction to effects.

7 To test the transition, click the Run button in the Flash Builder toolbar, then switch states after the application starts.

Modify user interfaces using skins

Skin classes modify the appearance of controls in a user interface. The way you create, edit, and import skins differs for Spark components and MX components.

About Spark skins

Spark skins control all visual elements of a component, including layout. Spark skins can contain multiple elements, such as graphic elements, text, images, and transitions. Spark skins support states. You can use a skin to define the appearance of a component for each of the component's states. Skins typically specify minimum sizing requirements for the component. For details on how Spark skins are implemented in Flex, see About Spark skins.

About skins for MX components

Skins for MX components can be either a bitmap graphic or a vector graphic. A bitmap graphic, called a graphical skin, is made up of individual pixels that together form an image. A vector graphic, called a programmatic skin, consists of a set of line definitions that specify a line’s starting and end point, thickness, color, and other information required by

Adobe® Flash® Player to draw the line. For details on how skins are implemented for MX components in Flex, see

About MX component skinning.

You can use Flash Builder to import skin artwork for MX components. See “ Import skin artwork for MX components ” on page 164.

The mx.skins.spark

package defines Spark skins for MX components.

• (Advanced Users) Do either of the following if you are familiar with creating Skin classes:

Remove ActionScript styling code or do not create a copy of an existing class.

If you do not create a copy of an existing class, Flash Builder generates a blank Skin class file with some comments to guide you.

The remaining steps of this procedure assume that you followed the Recommended option for generating a Skin class.

Import skin artwork for MX components

You use the Import Skin Artwork wizard to import both vector graphics artwork and bitmap artwork from the CS5 or higher versions of Flash Professional, Fireworks, Illustrator, and Photoshop. For bitmap artwork, any .PNG, .JPG, or

.GIF can be used. The artwork can then be used as skins for Flex components.

Note: Adobe provides a set of skinning templates to make it easy to create skins for the built-in Flex components. Use the templates with Flash, Fireworks, Illustrator, or Photoshop to create the artwork. You can also use Flash to create fully functional custom Flex components. For more information, see the articles in Importing Flash Professional Assets into Flex .

• Click Next.

3 In the next Import Skin Artwork dialog box, select the skins you want to import and specify which CSS style type and skin part property will be used. You can check items one at a time or click Check All or Uncheck All.

• If items do not have a valid style or skin part property name, they will not be checked by default. The following examples show the naming convention used in Flash Builder:

• Button_upSkin

• Button_glow_downSkin (maps to downSkin property of Button.glow style rule)

• TabBar-tab_upSkin (upSkin property maps to tabStyleName property of TabBar style rule)

• MyCustomComponent_borderSkin

For custom components, the item is checked if the component has been defined somewhere within the project you are importing to.

• If necessary, choose a style and skin part for the pop-up menus in each column.

• Click Finish.

A CSS file is created and displayed in the Source view. The CSS file is attached to the application specified in the wizard. If you import a SWC file, it is automatically added to the library path for the project.

Add interactivity with effects

An effect is a visible or audible change to the target component that occurs over a time, measured in milliseconds.

Examples of effects are fading, resizing, or moving a component.

Effects are initiated in response to an event, where the event is often initiated by a user action, such as a button click.

However, you can initiate effects programmatically or in response to events that are not triggered by the user.

For example, you can create an effect for a TextInput component that causes it to bounce slightly when the user tabs to it, or you can create an effect for a Label component that causes it to fade out when the user passes the mouse over it.

You can define effects in Flash Builder as a property of an MXML component.

Effects are implemented differently for Spark and MX components. For information on creating effects in MXML and

ActionScript code, see Introduction to effects.

Generate custom item renderers

You can generate item renderers for list-based controls for desktop and mobile applications.

For desktop applications, you can generate custom item renderers for Spark list-based controls, such as List and

ComboBox. You can also use Spark item renderers with some MX controls, such as the MX DataGrid and MX Tree controls.

For mobile applications, you can generate custom item renderers for mobile list-based controls.

Use custom item renderers to control the display of a data item in a DataGroup, SkinnableDataContainer, or in a subclass of those containers. The appearance defined by an item renderer can include the font, background color, border, and any other visual aspects of the data item. An item renderer also defines the appearance of a data item when the user interacts with it. For example, the item renderer can display the data item one way when the user moves the mouse over the data item. It displays the differently when the user selects the data item by clicking it.

Using Flash Builder, you can generate and edit item renderers. When Flash Builder generates item renderers for a desktop application, it uses one of the following templates:

• Spark components

Use this template for Spark list-based controls, such as List and ComboBox.

• MX Advanced DataGrid

• MX DataGrid

• MX Tree

When Flash Builder generates item renderers for list-based controls in a mobile application, it uses one of the following templates:

• Icon item renderer

Use this template to create a customized item renderer for list-based controls by specifying the label, message, and icon properties. The item renderer file is created in MXML.

• Custom ActionScript item renderer

Use this template to create a basic item renderer for list-based controls. You can then customize the item renderer to define the appearance of the list, as necessary. The item renderer file is created in ActionScript.

Create and edit item renderers

You can open the New Item Renderer wizard from the MXML editor. In the New Item Renderer wizard, you specify a name and template for the item renderer. Flash Builder generates an MXMLor ActionScript file that implements the item renderer.

Components in the application reference the generated item renderer using the itemRenderer property.

For example, do the following to create an item renderer for a Spark List component.

1 In the MXML editor, place your cursor inside a <s:List> tag and type the following:

<s:List itemRender="

Generate event handlers

Applications built with Flex are event-driven. User interface components respond to various events, such as a user clicking a button or the initialization of an object is complete. You write event handlers in ActionScript code that define how the component responds to the event.

Note: You can also generate event handlers for non-visible items such as RemoteObject and HTTPService.

Flash Builder provides event handler assistance that generates the event handler functions for a component. Within the generated function, you write the code that defines the component behavior in response to the event.

Content assist for an item in the MXML editor lets you access event handler assistance.

About generated event handlers

When Flash Builder generates an event handler function, it places the event handler in the first Script block of the file.

The function is placed at the end of the Script block. The generated event handler has protected access and accepts the appropriate subclass of Event as its only parameter.

Flash Builder generates a unique name for the event handler based on the component’s class name or a custom name for the event handler that you specify. If you do not specify a custom name, the name is generated according to the following process:

• If an id property is defined, Flash Builder bases the name on the id property.

• If there is no id property defined for the component, Flash Builder generates a unique name, based on the component’s class name.

You provide the body of the event handler. The following code block shows a generated event handler for a Button.

. . .

<fx:Script>

<![CDATA[ protected function myButton_clickHandler(event:MouseEvent):void

{

// TODO Auto-generated method stub

}

]]>

</fx:Script>

<s:Button label="Button" id="myButton" click="myButton_clickHandler(event)"/>

. . .

Flash Builder designates a default event for each user interface component. For example, the default event for a Button is the click event.

Generating event handlers for components

Note: If you specify a custom name for the event handler, then Flash Builder cannot generate the handler. If you want to use a custom name, first generate an event handler and then modify the name of the handler in both the event property and the generated handler.

Add the code for your implementation of the event handler to the generated event handler function.

Access data services

In Flash Builder, you interact with data and the data-driven controls directly in your MXML and ActionScript code.

You can work with data, automatically generate database applications, generate and use proxy code for web services, and generate and use code that works with the Flex Ajax Bridge. You can also manage Adobe Flash Player data access security issues and use Flash Builder with a proxy service.

Work with data in Flash Builder

You work with data in Flash Builder by directly modifying your MXML and ActionScript application code.

Data-driven controls and containers

Flex provides control and container components from which you build your application user interface. A number of these components present data, which users can select and interact with when using the application. Here are a few examples of how data-driven controls are used:

• On an address form, you can provide a way for users to select their home country (or other typical form input) by using the ComboBox or List controls.

• In a shopping cart application, you can use a Spark List component to present product data that includes images.

For the List component you can specify the layout as VerticalLayout, HorizontalLayout, or TileLayout.

• You can provide standard navigation options by using containers such as the TabBar and ButtonBar controls.

You provide data input to all of the data-driven controls with a data provider.

For information about using the data-driven controls, see Spark list-based controls.

Data providers and collections

A collection object contains a data object, such as an Array or an XMList object, and provides a set of methods that let you access, sort, filter, and modify the data items in that data object. Several Adobe Flex controls, known as data

provider controls, have a dataProvider property that you populate with a collection.

The following simple example shows how a data provider is defined (as an ActionScript ArrayCollection) and used by a control:

Remote data access

Flex contains data access components that are based on a service-oriented architecture (SOA). These components use remote procedure calls to interact with server environments, such as PHP, Adobe ColdFusion, and Microsoft

ASP.NET, to provide data to applications and send data to back-end data sources.

Last updated 12/3/2012

USING FLASH BUILDER

Develop Web and Desktop Applications in Flash Builder

Depending on the type of interfaces you have to a particular server-side application, you can connect to an application by using one of the following methods:

• HTTP GET or POST by using the HTTPService component

• SOAP-compliant web services by using the WebService component

• Adobe Action Message Format (AMF) remoting services by using the RemoteObject component

Note: When you use Flash Builder to develop applications that access server-side data, use a cross-domain.xml

file or a proxy if data is accessed from a domain other than the domain from which the application was loaded.

You can also use Flash Builder to build applications that use Adobe LiveCycle Data Services, a separate product that provides advanced data service features. LiveCycle Data Services provides proxying for remote procedure call (RPC) service applications as well as advanced security configuration. LiveCycle Data Services also provides the following data services:

Data Management Service Allows you to create applications that work with distributed data. The Data Management

Service also lets you manage large collections of data and nested data relationships, such as one-to-one and one-tomany relationships.

Message Service Allows you to create applications that can send messages to and receive messages from other applications, including applications built in Flex and Java Message Service (JMS) applications.

Data binding

In the code example in “ Data providers and collections ” on page 169, you may have noticed that the value of the

ComboBox control’s dataProvider property is "{complexDP}" . This is an example of data binding.

Data binding copies the value of an object (the source) to another object (the destination). After an object is bound to another object, changes made to the source are automatically reflected in the destination.

The following example binds the text property of a TextInput control (the source) to the text property of a Label control (the destination), so that text entered in the TextInput control is displayed by the Label control:

<?xml version="1.0" encoding="utf-8"?>

<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"

xmlns:s="library://ns.adobe.com/flex/spark"

xmlns:mx="library://ns.adobe.com/flex/mx" minWidth="955" minHeight="600">

<fx:Declarations>

<!-- Place non-visual elements (e.g., services, value objects) here -->

</fx:Declarations>

<s:TextInput id="LNameInput" x="10" y="10"/>

<s:Label text="{LNameInput.text}" x="10" y="50"/>

</s:Application>

To bind data from one object to another, you use either the curly brackets ({ }) syntax (as shown in the example) or the

<fx:Binding> tag. For more information, see Using data binding with data models and Data binding.

Data models

A data model is an object that you can use to temporarily store data in memory so that it can be easily manipulated.

You can define a data model in ActionScript, in MXML by using a tag such as <fx:Model> , or by using any object that contains properties. As an example, the following data model shows information such as a person’s name, age, and phone number:

171

Last updated 12/3/2012

USING FLASH BUILDER

Develop Web and Desktop Applications in Flash Builder

<fx:Declarations>

<fx:Model id="reg">

<registration>

<name>{nme.text}</name>

<email>{email.text}</email>

<phone>{phone.text}</phone>

<zip>{zip.text}</zip>

<ssn>{ssn.text}</ssn>

</registration>

</fx:Model>

</fx:Declarations>

The fields of a data model can contain static data (as in the example), or you can use data binding to pass data to and from the data model.

You can also define the data model within an XML file. You then reference the XML file through the file system or through a URL by using the <fx:Model> tag’s source property, as the following example shows:

<fx:Model source="content.xml" id="Contacts"/>

<fx:Model source="http://www.somesite.com/companyinfo.xml" id="myCompany"/>

For more information about data models, see Storing data.

Data validation

You use data validation to ensure that the data the user enters into your application is valid. For example, if you want the user to enter a valid ZIP code you use a ZIP code data validator.

Flex provides predefined data validators for the following types of data: credit card, currency, date, email, number, phone number, regular expression, social security, string, and ZIP code.

Data validators are nonvisual Flex components, which means that you do not access them from the Components panel. Instead, you work with them in code, as the following MXML example shows:

<!-- Define the ZipCodeValidator. -->

<mx:ZipCodeValidator id="zcV" source="{zipcodeInput}" property="text"/>

<!-- Define the TextInput control for entering the zip code. -->

<s:TextInput id="zipcodeInput"/>

In this MXML example, the validator is defined with the appropriate MXML tag, and it is bound to the ID property of a TextInput control. At runtime, when the user enters the phone number into the TextInput control, the number is immediately validated.

You can use data validators in ActionScript by defining a variable as an instance of a validator class and then creating a function to bind it to the input control.

Data validators are often used with data models. For more information, see Validating Data.

Data formatting

To display the proper format of certain types of data in your application, you use a data formatter. Flex provides predefined data formatters for the following types of data: currency, date, number, phone, and ZIP code.

Data formatters are bound to input controls, and they format data correctly after the user enters it. For example, a user can enter a date in this format:

120105

Bound to the text input control is a data formatter that stores and displays the date in this format:

Configure access to data services

The New Project wizard for Flex projects and Flex Mobile projects provide options for configuring access to data services. The steps in the wizard are the same for both Flex projects and Flex mobile projects. You can configure access to the following types of services:

PHP services

ColdFusion services

Java services

ASP.NET

Configure access to PHP services

To access data from PHP services, a server hosting the services must be available. The server can be either a local server or a server available from a local network.

1 In the New Project wizard, specify Project Location. For Mobile projects, specify Mobile Settings.

See “ Flex projects

” on page 57 and “ Flex mobile projects ” on page 58.

2 For application server type, choose PHP.

3 Specify the Web Root and Root URL for the service. Click Validate Configuration.

Typically, you specify a Web root and root URL that is local to your environment. However, you can also access network servers. Make sure that the directory is a shared directory and the account under which Flash Builder is running has write access.

Make sure that you have mapped or mounted a drive for the network server. Then specify a path to the server. The path is platform-specific. For example:

(Windows) \\10.192.18.12\server\webroot

(Windows) Z:\webroot

(Mac) /Volumes/webroot

4 (Optional) Specify the output folder for your application.

5 Click Finish, or click Next to select more configuration options.

See “ Build paths, native extensions, and other project configuration options ” on page 61.

Configure access to ColdFusion services

To access data that uses ColdFusion, you must have Adobe ColdFusion 8 or a higher version of ColdFusion. For more information, see the ColdFusion product page .

1 In the New Project wizard, specify Project Location. For Mobile projects, specify Mobile Settings.

See “ Flex projects

2 For application server type, select ColdFusion, then choose from the following options:

Use Remote Object Access Service If you deselect Use Remote Object Access Service, specify your Web Root and

Web Root URL in the next step.

If you select Use Remote Object Access Service, you have the following choices:

• Data Services

Specify LiveCycle Data Services as a ColdFusion application type only if your ColdFusion installation is configured for LiveCycle Data Services. See Integrating Adobe LiveCycle Data Services ES 2.6 with Adobe

ColdFusion 8 .

Typically for LiveCycle Data Services, you specify Java as the application server type, not ColdFusion. See

“ Configure access to Java services ” on page 175.

• BlazeDS

Specify BlazeDS as a ColdFusion application type only if your ColdFusion installation is configured for Adobe

BlazeDS. See Integrating BlazeDS with a ColdFusion 8 Installation .

Typically for BlazeDS, you specify Java as the application server type, not ColdFusion. See “ Configure access to

Java services ” on page 175.

• ColdFusion Flash Remoting

Use this option if you plan to use data-centric development tools available with Flash Builder. This option also applies if you use Flash Remoting to invoke methods in ColdFusion Components (CFCs). See Building datacentric applications with Flash Builder.

3 Specify a server location, Web Root, Web Root URL, and Context Root:

If accessing a remote object service, you can configure a stand-alone ColdFusion configuration or a ColdFusion configuration deployed to a Java application server:

• Standalone

Use the Standalone option if your ColdFusion installation uses the server configuration.

Specify the location of the ColdFusion server, location of the Web Root, and Web Root URL.

• Deployed to Java Application Server

Use the Deployed to Java Application Server option if your ColdFusion installation uses either the multiserver or Java configurations.

Specify a Web Root, Root URL, and Context Root. If you are using the ColdFusion multiserver configuration, you typically do not have to specify the Context Root.

The context root typically matches the last segment of the root URL path when you deploy ColdFusion as a web application in the ColdFusion Java configuration.

When specifying the location of the server and web root, navigate to a local directory or specify a path to a directory on a network server. Make sure that the directory is a shared directory and the account under which Flash Builder is running has write access.

Make sure that you have mapped or mounted a network drive for the network server. The path to a network server is platform-specific. For example:

(Windows) \\10.192.18.12\server\webroot

(Windows) Z:\webroot

Configure access to Java services

This project configuration lets you create Flex projects that use Java-based service classes with the remote object access service option. When no option is selected, and Java server is used, an output folder is created under the server root.

If you installed the Eclipse Web Tools Project (WTP) plug-in, you can create combined Java and Flex projects with or without remote object access service.

Note: LiveCycle Data Services and BlazeDS support specific versions of the Flex SDK. Check the LiveCycle Data Services

Compatibility Matrix to see which versions of the Flex SDK your version of LiveCycle Data Service supports. The compatibility matrix also lists the versions of the Flex SDK that BlazeDS supports.

1 In the New Project wizard, specify Project Location. For Mobile projects, specify Mobile Settings.

See “ Flex projects

” on page 57 and “ Flex mobile projects ” on page 58.

2 For application server type, choose Java.

3 (Optional) Select the Use Remote Object Access Service option.

Data Services ES is automatically selected. You can select BlazeDS. If you installed WTP, you can also create a combined Java and Flex project that uses WTP (the Java source folder is selected for you).

4 Configure the Java application server.

• If you selected the Use Remote Access Service and Data Services ES or BlazeDS options, specify the root settings:

Root Folder Physical location of the web application server that serves your application’s data (for example,

C:\Program Files\Apache Software Foundation\Tomcat 5.5\webapps\myservices ). If you are using a remote server, it must be on a mapped drive or accessible using UNC.

Root URL Root URL of the web application. This URL corresponds to the physical location named in Root

Folder, above. For BlazeDS on Tomcat, this URL can be: http://localhost:8080/myservices

For Data Services, the default root URL is: http://localhost:8400/lcds/

If you use a remote server, the URL can be as follows: http://myserver.com:8400/lcds/ .

Context Root The context root typically matches the last segment of the root URL path. For the examples in

Root URL, above, the context root would be /myservices for BlazeDS and /lcds for Data Service.

Managing Flash Player security

Flash Player does not allow an application to receive data from a domain other than the domain from which it was loaded, unless it has been given explicit permission. If you load your application SWF file from http://mydomain.com, it cannot load data from http://yourdomain.com. This security sandbox prevents malicious use of Flash Player capabilities. (JavaScript uses a similar security model to prevent malicious use of JavaScript.)

To access data from an application built in Flex, place your application SWF file on the same server that hosts the data service, or do one of the following:

Use cross-domain policy files

A cross-domain policy file is a simple XML file that gives Flash Player permission to access data from a domain other than the domain on which the application resides. Without this policy file, the user is prompted to grant access permission through a dialog box. You want to avoid this situation.

The cross-domain policy file (named crossdomain.xml) is placed in the root of the server (or servers) containing the data that you want to access. The following example shows a cross-domain policy file:

<?xml version="1.0"?>

<!DOCTYPE cross-domain-policy SYSTEM "http://www.adobe.com/xml/dtds/cross-domain-policy.dtd">

<cross-domain-policy>

<allow-access-from domain="www.yourdomain.com" />

</cross-domain-policy>

For more information about configuring cross-domain policy files, see Security .

Set up Flash Builder to use a proxy for accessing remote data

On the same server that contains your application SWF file, create a proxy that calls a data service hosted on another server.

The proxy service processes requests from the application to the remote service and responses from the remote service back to the application (Flash Player).

When developing your applications, a common technique is to host the proxy on your local computer. To do so, run a web server and scripting language on your local development computer.

After you have set up a proxy to access data from a remote service, you place the application files in the same domain as the proxy. In Flash Builder, you can modify both the project build settings and the launch configuration to manage the use of a proxy.

If you use Flash Builder to compile your applications and the proxy server is also set up on your local development computer, you can modify the project build settings to automatically copy the compiled application files to the appropriate location on your web server.

Modify the project build path

1 In the Flex Package Explorer, select a project.

2 Right-click and select Properties. The Project Properties dialog box appears.

3 Select the Flex Build Path properties page.

4 Change the existing output folder by entering a new path or by browsing to the appropriate folder of your web server (for example, C:\inetpub\wwwroot\myApp\).

5 Click OK.

To run and debug the application from the web server, modify the project’s launch configuration as required.

Monitor applications that access data services

The Network Monitor is a useful tool for monitoring and debugging applications that access data services. The

Network Monitor allows you to examine the data that flows between an application and a data service. It also examines

XML, AMF, and JSON data, which are sent using SOAP, AMF, HTTP, and HTTPS protocols.

The Network Monitor is active in the Flash Development and Flash Debug perspectives.

Enable network monitoring

You enable the Network Monitor for individual Flex projects. The monitor state (enabled or disabled) applies to all applications within that project. You cannot enable or disable the Network Monitor on an individual application basis.

By default the Network Monitor is not enabled. You enable the Network Monitor by selecting the Enable Monitor icon in the Network Monitor toolbar.

This procedure assumes that you are in the Flex Development or Flex Debug perspective.

1

Builder > Network Monitor.

2 If the Network Monitor is not enabled, in the Network Monitor toolbar click the Enable Network Monitor button.

This button is a toggle for enabling or disabling the Network Monitor.

Monitor remote services

To monitor your application, run either the development or debug version of the application with the Network

Monitor enabled.

In general, the Network Monitor captures and stores all event data until you either quit the application or explicitly clear the data. The events are displayed in chronological order.

Start a monitoring session

1 Run either a development or debug version of the application that accesses remote services.

2 For each access to a remote service, the Network Monitor lists the following:

• Time of the request

• Requesting service

• The operation and URL if applicable

• The time of the response

• Elapsed time

3 Select a column header to sort the returned data according to the values in that column.

Click the column again to invert the order of the data.

4 Select the request and parameter tabs at the bottom of the monitor to view the details about the request operation.

The actual data sent in the request, as well as other information about the request, can be viewed from these tabs.

6 Double-click an entry to go to the source code for that operation.

The Flash Builder source editor opens with the relevant line of source code highlighted.

Note: For most events, the Network Monitor can correlate an event with the Flex source code. For some events that are triggered outside the scope of the Network Monitor, the monitor cannot find the Flex source code.

7 Click the Save button on the Network Monitor toolbar to write all captured information to an XML file.

Note: Use the generated XML file to study the data offline. You cannot import the data from this file back into the

Network Monitor.

8 Click the Clear icon in the Network Monitor toolbar to remove all captured information from the monitor.

Suspend a monitoring session

You can suspend and resume network monitoring. Suspending and resuming a session applies to all applications in the Flex project. For example, you cannot suspend one application in the project and continue monitoring another.

1 Click the Suspend button in the Network Monitor toolbar to suspend the monitoring of a session.

2 Click the Resume button in the toolbar to continue monitoring the session.

Stop a monitoring session

To stop monitoring a session, you disable the Network Monitor.

1 (Optional) Close the Network Monitor.

Note: Simply closing the Network Monitor does not stop the monitoring session. Monitoring is still active, even if the

Network Monitor is closed.

2 Click the Enable Network Monitor button.

This button is a toggle for enabling or disabling the Network Monitor.

Note: Disabling the Network Monitor applies to all applications in the Flex project.

Support for HTTPS protocol

The Network Monitor supports monitoring HTTPS calls to a server certified by a certificate authority (CA) or that has a self-signed certificate.

To monitor calls over the HTTPS protocol, modify the default preference for the Network Monitor to ignore SSL security checks. Open the Preferences dialog and navigate to Flash Builder > Network Monitor.

View Network Monitor data

The leftmost panel of the Network Monitor provides information about the source of the data. It displays the following information:

• Source URL for the data service

• The type of service displayed

For example RemoteService, HTTPService, or WebService.

• The request time, response time, and elapsed time for the data request

• The name of the operation called from the data service.

USING FLASH BUILDER

Develop Web and Desktop Applications in Flash Builder

The Network Monitor has two tabs for viewing data, allowing you to view the request data and response data.

For each request and response, you can view the data in Tree View, Raw View, or Hex view. Select the corresponding icon for each view to change how the Network Monitor displays the data.

• Tree View

Shows the XML, JSON, and AMF data in a tree structure format. This is the default view for data.

• Raw View

Shows the actual data that is transferred.

• Hex View

Shows the data in hexadecimal format. Hex view is useful when debugging binary data sent over a network.

By default, the Network Monitor clears all recorded data with every launch of an application. However, you can change the default behavior and retain all monitor data. Retained monitor data includes the data from all applications in all projects. Open the Preference dialog and navigate to Flash Builder > Network Monitor. Deselect Clear Entries on Start.

Save Network Monitor data

You can save Network Monitor data to an XML. Click the Save button in the Network Monitor view to save Network

Monitor data.

Monitor multiple applications

You can monitor multiple applications simultaneously. There are two scenarios for monitoring multiple applications:

• Monitoring multiple applications in the same project

You can only have one Network Monitor per Flex project. When monitoring multiple applications in the same project, events from all applications appear in the monitor according to the time the event occurred.

You cannot filter events in the monitor according to specific applications.

• Monitoring multiple applications in different projects

You can open a Network Monitor for each active Flex project. Each Network Monitor is independent of the other monitor, displaying only the events for its specific project.

Suspending or disabling a Network Monitor in one project does not apply to monitors in other projects.

Monitor mobile applications

The Network Monitor lets you examine the data that flows between a mobile application and a data service.

You can enable the Network Monitor to monitor mobile applications by following these steps:

1 Run the debug configuration of the application with the Network Monitor enabled.

2 Specify a launch method.

• On Desktop Select this launch method if you don’t have a mobile device and you want to monitor the application on your desktop.

Select On AIR Simulator to monitor the application on a simulated device that is created using the AIR Debug

Launcher (ADL). The device is simulated according to the device configuration that you select.

• On Device Select this launch method to monitor the application on a mobile device.

Typically, you use the On Device launch method to monitor applications that access the device’s native code.

Flash Builder can access the device either by connecting to your computer’s USB port or over the network via

Wi-Fi.

Whether you connect your device over USB or over Wi-Fi, the Network Monitor records calls only if the device and the host machine are connected to the same network via Wi-Fi.

If the Network Monitor cannot establish a connection via Wi-Fi, Flash Builder displays a dialog requesting the

IP address of the host machine. Once the connection is established, the network calls from the application are rerouted to Flash Builder via the device’s Wi-Fi network.

3 Monitor the mobile application as you would monitor a web or desktop application that accesses data services. For more information, see Monitor applications that access data services .

Limitations of the Network Monitor

Be aware of the following limitations when monitoring network data:

• The Network Monitor does not support applications that were created using pure ActionScript and Library projects.

• The Network Monitor does not support the Real Time Messaging Protocol (RTMP). For example, you cannot monitor streaming video.

181

Use Flex library projects

Library projects let you build custom code libraries that you can share between your applications or distribute to other developers. A library project generates a SWC file, which is an archive file for Flex components and other resources.

For example, the Flex framework is contained in SWC files.

When you create a Flex project, the Flex framework SWC files are added to the project’s library path. Adding the library to a project lets you use those components in your application and also enables code hinting for those components.

You can view and edit the library path by accessing the project’s build path properties page. For Flex projects, select

Project > Properties > Flex Build Path.

In addition to providing a convenient way to package and distribute components, SWC libraries are used as themes, the visual appearance of applications built in Flex. A SWC theme file contains a CSS file and all the related graphic assets. For more information about creating and using themes, see About themes.

Configure libraries for your applications

You use SWC libraries in your projects in the following ways:

Merged into the application When you add a SWC file to the project’s library path, the components contained in the library are available to use in your application. When you build the application, only the library components you actually used are compiled into the application SWF file. In other words, all of your application code is merged into a single SWF file. This is the most common and straightforward way of using library components.

External to the application You can keep library components separate from the compiled SWF file, so they are not merged into the file. The compiler resolves all code contained in the library that is used by the application, but does not merge the code into the application SWF file. The advantage of this approach is that you make the application SWF file smaller. The components contained in the SWC file are retrieved and loaded into memory as needed, at runtime.

Runtime Shared Library In Flex projects only, you can also use SWC files as a Runtime Shared Library (RSL), which is similar to a dynamically linked library on other platforms. Use SWC files as an RSL when you have a collection of components that are used by more than one application.

There are several advantages to sharing components between applications by using an RSL. First, the library is loaded into memory once, cached, and then available to all the applications that use those components. Second, the components contained within the library are only loaded when they are needed, which reduces the application’s startup time because the size of each application is smaller. The potential problem to this approach is that the entire

RSL is loaded into memory, rather than the individual components that the applications use. For more information about when to use SWC files as an RSL, see Runtime Shared Libraries.

Create Flex library projects

When you create a library project, the New Flex Library Project wizard guides you through the steps, prompting you for the project name, location, and build path information.

The first step in creating a SWC file in Flash Builder is to create a Flex Library project. After you create the Library project, you add components, specify the library project elements to include in the SWC file, and then build the project to generate the SWC file.

1

2 Enter a Project name, and then specify the following:

Project Location The default location is the current workspace. On Windows platforms, the default workspace location is C:\Documents and Settings\username\Adobe Flash Builder\. On the Macintosh, the default workspace location is /Users/username/Adobe Flash Builder/. You can choose a different project location by deselecting the

Use Default Location option.

Configuration You can specify if the Flex Library project uses generic libraries or mobile libraries. Generic libraries are used for web, desktop, and mobile projects.

You can also specify if the Flex Library project has to be compatible with Flash Catalyst. In that case, generic libraries are used. Mobile libraries are not supported for Flash Catalyst compatible projects.

Flex SDK Version Choose default or specific. You can also click the Configure SDKs link to add, edit, or remove

SDKs on the main Preferences page.

Include Adobe AIR libraries Select this option if your library must use AIR features, such as access to the AIR APIs.

Flash Builder then changes the library path of this new Flex Library project so that it includes airglobal.swc and airframework.swc. Web-based Flex projects cannot use this library.

Do not select this option if you are writing a generic library intended to be used only in a web-based application, or in either a web-based or AIR-based application.

3 Click Next.

4 (Optional) Set the build path information. For example, you can add folders to the project’s source path that contains the components to include in the SWC file. You can also add other projects, folder, or library SWC files

to include in your library project. See “ Use SWC files in your projects ” on page 184.

5 When you finish entering the project settings, click Finish.

For best practices while creating Flex libraries, see the article Three points to remember when creating a library by Adobe Flex Community Expert, Xavi Beumala.

Create an AIR library project

To create an AIR code library for multiple Adobe AIR projects, create an Adobe AIR library project using the standard

Flex library project wizard.

1

2 Specify a project name.

3 Select Include Adobe AIR Libraries and then click Next.

4 Modify the build path as needed and then click Finish. For more information about creating library projects, see

“About library projects” in the Flash Builder Help.

Add components to the library project

You add components to the library project in the following ways:

• Add new or existing custom components, ActionScript classes, and other assets to the project.

•

Link to existing components in other projects in the workspace. (See “ Link to resources outside the project workspace ” on page 69.)

•

Add a linked folder that contains components to the library project’s source path. (See “ Add an external resource folder to the source path ” on page 71.)

Note: All the components you include in the library project must be associated with the library project (directly or as linked resources).

Select library project elements to include in the SWC file

To select the elements (components and resources) to include in the SWC, follow these steps:

1 Select Project > Properties > Flex Library Build Path.

The components that you added to the project (either directly or by linking to them) appear in the Classes tab.

2 Select the component classes to include in the SWC file.

3 (Optional) Select the Resources tab and then select the resources to include in the SWC file.

4 After you make your selections, click OK.

Build library projects

After you select elements to include in the SWC file, and if you selected the Build Automatically option, the SWC file is immediately compiled and generated into the project’s output folder. If you build your projects manually, you can build the library project when you want by selecting Project > Build Project or Build All.

Building your library project generates a SWC file, which you can share with other applications or users.

A SWC file is an archive file. You can open the SWC file in any archive utility, such as Winzip. Inside the SWC file are the library.swf and catalog.xml files. There also are properties files and other embedded assets.

You can export the library as an open directory rather than as a SWC file. You typically export a library as an open directory when you plan on using the library.swf file inside the SWC file as an RSL.

You do this by setting the directory and output compiler options. You set the output option to the name of a directory to create, and set the directory option to true to indicate that you want an open directory and not a SWC file when you build the library. To edit the compiler options, select Project > Properties > Flex Library Compiler, and add the options to the “Additional compiler arguments” field; for example:

-directory=true -output=myOpenDir

Flash Builder creates a directory in the project named myOpenDir and stores the contents of the SWC file in that directory.

Use SWC files in your projects

To use SWC files in your Flex projects, you add them to the project’s library path. The SWC files can be located in the project, in a Flex library project, in a shared folder within the workspace, or any other location that has been linked to the project (using a shared folder that was added to the project’s source path, for example).

When you use SWC files in applications, there are configuration options that determine whether they are statically or dynamically linked to the application, merged into the application SWF file, or external to it and accessed separately at runtime.

Add a SWC file to the library path

1 With a project selected in the Package Explorer, select Project > Properties > Flex Build Path.

2 Click the Library Path tab.

3 Select any of these options to add SWC files:

Add Project Adds a Flex library project.

Add SWC Folder Lets you add a folder that contains SWC files.

Add SWC Adds a compiled SWC file.

Add Flex SDK Lets you add other Flex SDKs. If your project already has a Flex SDK in its library path, this button is disabled. If you remove the existing Flex SDK from your library path, the button is enabled. When you click this button, a Flex SDK node is added, but you are not prompted which one is added. To control which Flex SDK to use, select Project > Properties > Flex Compiler.

4 Enter or browse to and select the location of the SWC file, project, or folder. Click OK.

The SWC file, library project, or folder is added to the library path.

Merge the SWC file into the application SWF file when compiled

1 With a project selected in the Package Explorer, select Project > Properties > Flex Build Path.

2 Click the Library Path tab, and then select and expand the SWC file entry to display the SWC options.

3 Double-click the Link Type option. The Library Path Items Options dialog box appears.

4 Select the Merged into Code option, and click OK.

This procedure is the equivalent of using the library-path compiler option.

Set the SWC file as an external library file

1 With a project selected in the Package Explorer, select Project > Properties > Flex Build Path.

2 Select the Library Path tab, and then select and expand the SWC file entry to display the SWC options.

3 Double-click the Link Type option. The Library Path Items Options dialog box appears.

4 Select the External option, and click OK.

This procedure is the equivalent of using the external-library-path compiler option.

Use the SWC file as an RSL

You can externalize the shared assets in your applications’ SWF files into stand-alone files. These stand-alone files can be separately downloaded and cached on the client. The shared assets are transferred and loaded only once to the client but any number of applications can use them at runtime. These shared files are known as Runtime Shared Libraries or

RSLs.

1 With a project selected in the Package Explorer, select Project > Properties > Flex Build Path.

2 Select the Library Path tab, and then select and expand the SWC file entry to display the SWC options.

3 Double-click the Link Type option or click Edit. The Library Path Items Options dialog box appears.

4 Select Run-time Shared Library (RSL) as the link type.

5 You can add a URL to specify where the SWC library resides when the application is deployed. You can also edit an existing URL, if necessary.

6 Select Force Load RSL to force-load an unused RSL during compile time.

7 You can specify the application domain in which the cross-domain RSLs have to be loaded.

Using the SWC files as an RSL simplifies the process for using RSLs manually. To do so, you extract the SWF file from the SWC file and set the values of the runtime-shared-library-path compiler option.

For more information about using SWC files as an RSL, see Runtime Shared Librariesin Using Adobe Flex.

Create ActionScript library projects

The New ActionScript Library Project wizard guides you through creating an ActionScript library project, prompting you for the project name, location, and build path information.

1

2 Enter a Project name, and then specify the following:

Project Location The default location is the current workspace. On Windows, the default workspace location is

C:\Documents and Settings\username\Adobe Flash Builder\. On the Macintosh, the default workspace location is

/Users/username/Adobe Flash Builder/. You can choose a different project location by deselecting the Use Default

Location option.

Flex SDK Version Choose default or specific. You can also click the Configure SDKs link to add, edit, or remove

SDKs on the main Preferences page.

Use Legacy Compiler For ActionScript projects, Flash Builder uses the ActionScript Compiler (ASC) by default. If you are using Adobe Flex SDK 4.6 or an earlier version of the Flex SDK, select Use Legacy Compiler to use the older compiler.

Include Adobe AIR libraries Select this option if your library must use Adobe AIR features, such as access to the

Adobe AIR APIs. Flash Builder then changes the library path of this new ActionScript Library project so that it includes airglobal.swc and airframework.swc.

Web-based Flex projects cannot use this library. Do not select this option if you are writing a generic library intended to be used only in a web-based application, or in either a web-based or AIR-based application.

3 Click Next.

4 (Optional) Set the build path information. For example, you can add folders to the project’s source path that contains the components to include in the SWC file. You can also add other projects, folder, or library SWC files

to include in your library project. See “ Use SWC files in your projects ” on page 184.

Create custom MXML components

You can create custom components to add functionality to an existing component, or to build a reusable component, like a search box or the display of an item in a data grid. You can also write a new component that isn’t available in the

Flex framework.

You can distribute the components using SWC files. For more information, see “ Use SWC files in your projects ” on page 184.

If your component is composed mostly of existing components, it is convenient to define it using MXML. However,

if it is a new type of component, define it as an ActionScript component. For more information, see “ Create an

ActionScript class ” on page 65.

1

The New MXML Component dialog box appears:

2 Specify the parent folder for your custom component file.

Save the file in a folder in the current project folder or in the source path of the current project if you want the component to appear in the Components view.

3 Specify a filename for the component.

The filename defines the component name. For example, if you name the file LoginBox.mxml

, the component is named LoginBox.

4 In the Based On field, select the base component of your custom component.

Custom components are typically derived from existing components. Containers are commonly used as the base components of layout custom components.

Starting with Flex 4, Flash Builder suggests spark.components.Group as the base component.

Select Browse to open the Open Type dialog and select a component.

Modify or clear the suggested component to broaden the selection in the Open Type dialog. For example, specify

spark.components. before clicking Browse.

You can filter the selection in the Open Type dialog, based on your needs. See “ Browse and view classes ” on page 30

for information on using the Open Type dialog.

5 (Optional) If you base the component on any container, you get options to set the width and height of the component.

You can set these options to a fixed width and height or to percentages, or you can clear them. When you create an instance of the component, you can override the component’s width and height in the instance.

6 Click Finish.

Flash Builder saves the file in the parent folder and opens it in the editor.

7 Create your custom component.

For more information, see Simple MXML components.

You can distribute custom components by creating library projects. For more information, see “ Use Flex library projects ” on page 181.

Provide ASDoc comments for custom components

You can document your custom components by adding ASDoc comments to the code that implements the components. ASDoc comments are then available with Content Assist in the MXML and ActionScript editors. For

more information, see “ Content Assist, Quick Assist, and Quick Fix ” on page 14.

Add ASDoc comments to ActionScript source files to provide API reference documentation. You can also add ASDoc comments to document MXML elements. See ASDoc for details on creating ASDoc comments for your source files.

187

Create modules

You can create, add, optimize, and debug modules in Flash Builder. For information on writing module code, see

Modular applications.

The following steps describe how to create a module in Flash Builder. After you create a module, you can compile it.

1

2 Select a parent directory for the module. You typically store modules in the same directory as the main application so that relative paths to shared resources are the same.

Because modules are runnable, they must be in the project’s source folder.

3 Enter a filename for the module; for example, MyModule.

4 Enter the Width, Height, and Layout properties for the module.

5 Specify whether to optimize the module.

If you optimize a module for an application, classes used by the application are excluded from the module. This can

result in smaller download sizes for your SWF files. For more information, see “ Optimize modules in Flash Builder ” on page 191.

• Optimize for Application

If you select this option, specify an application to optimize the module against.

• Do Not Optimize

If you select this option, all classes are included in the module, whether they are defined in the main application.

This can improve the performance of the incremental compilation. In addition, you can load the module into any application because it has all of its dependencies compiled into it.

6 Click Finish.

Flash Builder adds a new MXML module file in your project.

Compile modules

In Flash Builder, you can either run the module as if it were an application or you can build the module’s project. If the modules are in the same project as your application, then when you run your application, Flash Builder compiles

SWF files for all modules in the project. The SWF files are then loaded into the application at runtime.

You cannot run the module-based SWF file as a stand-alone SWF file or load it into a browser window. It must be loaded by an application as a module. If you run the module in Flash Builder to compile it, close Adobe Flash Player or the browser window and ignore any errors. Modules should not be requested by the Player or through a browser directly.

Last updated 12/3/2012

USING FLASH BUILDER

Develop Web and Desktop Applications in Flash Builder

The module SWF files and main application SWF file are typically in the same directory, although Flash Builder compiles the modules at the same time as your application, regardless of their location. Modules can be in the same directory as the application or in subdirectories.

You can also create a separate Flex or ActionScript project for each module or for groups of modules. This gives you greater control over how modules are compiled because each project can have different compiler options than the application or other modules. It also lets you compile the module’s project or projects without compiling the application. However, this approach requires that you manually compile each module before compiling the application. One way to do this is to compile all open projects in Flash Builder at one time.

If you compile modules separately from the main application, be sure to include or exclude debugging information,

based on whether you want to debug your application and modules. For more information, see “ Debug modules in

Flash Builder ” on page 191.

The Flash Builder workflow is designed around associating modules with a single application. If you want to use modules across multiple applications, consider encapsulating the code in a library component or class and including that in a simple module for each application. Modules are not intended to be used for cross-application code reuse; that is for libraries.

Use multiple projects for modules

When you set up your project’s architecture, you can decide to include modules in your application’s project, create a separate project for each module, or create a separate project for all modules.

Use one project for each module

Using one project for each module has the following benefits:

• Module projects can be located anywhere in the workspace.

• Module projects can have their own compiler settings, such as a custom library path.

Module projects can use the load-externs compiler option to remove overlapping dependencies.

Using one project for each module has the following drawbacks:

• Many projects use more memory.

• Many projects in a single workspace can make the workspace crowded.

• By default, when you compile the application, not all module projects are compiled even if they have changed.

• To optimize your module’s file size, manually apply the load-externs and link-report compiler options.

Use one project for all modules

A related approach is to use a single project for all modules, while keeping the application in its own separate project.

This has some of the drawbacks of using a single project for both the application and the modules, but it has many of the same benefits as using a separate project for each module.

Using one project for all modules has the following benefits:

• The module project can be located anywhere in the workspace.

• You can compile just the modules or just the application, without having to recompile both at the same time.

• The module project can use the load-externs compiler option to remove overlapping dependencies.

Using one module project for all modules has the following drawbacks:

• All of the modules in the module project must use the same compiler settings, such as the library path.

• By default, when you compile the application, the module project is not compiled even if the module project has changed.

• To optimize your module’s file size, manually apply the load-externs and link-report compiler options.

Create projects for modules

When creating a separate project for modules, you change the module project’s output folder to a directory that the application uses. You also suppress the generation of wrapper files.

Create a separate project for modules in Flash Builder

1 Create a main project.

2 Create a project for your module or modules.

3 From the context menu for the module’s project, select Properties. The Properties dialog box appears.

4 Select the Flex Build Path option.

5 Change the Output Folder to point to the MainProject modules directory. For example, change it to the following:

${DOCUMENTS}\MainProject\assets

This redirects the output of your module’s compilation to your application project’s (MainProject) assets directory.

In your main application, you can point the ModuleLoader url property to the SWF files in the assets directory.

The value of this property is relative to the output folder.

6 Click OK to save your changes.

7 Open the project properties again and select the Flex Compiler option.

8 Deselect the Generate HTML Wrapper File option. This prevents the module’s project from generating the HTML wrapper files. You typically use these files only for the application. For modules, they are not necessary.

9 Click OK to apply the changes.

Compile projects for modules

Compiling multiple projects in Flash Builder is a common operation. First you choose the order in which you want to compile the projects. Then you compile all the projects at the same time.

Compile all projects at the same time in Flash Builder

❖ From the main menu, select Project > Build All.

Flex builds all projects in the workspace. The application files are added to each project’s output folder. If you haven’t already chosen to save files automatically before a build begins, you are prompted to save the files.

If you want to change the build order, use the Build Order dialog box. Changing the build order is not always necessary.

Projects that use modules need to be compiled only by the time the main project application runs, not as it is compiled.

In most cases, the default build order is adequate.

However, if you want to eliminate overlapping dependencies, you might need to change the build order so that the main application is compiled first. At that time, you use the link-report compiler option to generate the linker report. When you compile the modules, you use the load-externs compiler option to use the linker report that is

generated by the shell application. For more information on reducing module size, see “ Optimize modules in Flash

Builder ” on page 191.

Change the build order of the projects

1 Open the Preferences dialog and select General > Workspace > Build Order.

The Build Order dialog box appears.

2 Deselect the Use Default Build Order checkbox.

3 Use the Up and Down buttons to reorder the projects in the Project Build Order list. You can also use the Remove

Project button to remove projects that are not part of your main application or that are not modules used by the application. The removed project is built, but only after all the projects in the build order list are built.

4 Click OK.

5 Modify the build order as needed and then click OK.

If you create dependencies between separate projects in the workspace, the compiler automatically determines the order in which the projects are built, so these dependencies are resolved properly.

When you use a separate project for each module, you can compile a single module at a time. This can save time over compiling all projects at once, or over compiling a single project that contains all module and application files.

Compile a single module’s project

1 Right-click the module’s MXML file in the module’s project.

2 Select Run Application. The Player or browser window tries to run the module after it is compiled. You can close the Player or browser window and ignore any error messages that appear at runtime. Modules are not meant to be run in the Player or in a browser directly.

Add modules to your project

In some cases, you use modules that are not in your main application’s project. You can have the module in a separate project so that you can use custom configuration options, or you may want to share the module across multiple applications. Add the module’s source code to your application’s source path and then add the module to the application’s module list before you can use it in your project.

Add an already-compiled module to your project

1 Select the main application in the Flex Package Explorer.

2 Select Project > Properties > Flex Build Path to add the module’s source to the application project’s source path.

3 Click the Add Folder button and browse to the module’s source path. Click OK to select the module. Do so for each external module that you add to your application’s project.

4 Click OK again to save your changes.

5 Click Project > Properties > Flex Modules to add the module to the application’s module list. The Flex Modules dialog box lists all modules that have been added to the current project or that are in the current project. When you first create a project, this dialog box is empty.

6 Click the Add button. The Add Module dialog box appears.

7 Use the Browse button or enter the location of the module’s MXML file in the Source field. All modules that are in the project’s source path are available to add by using this dialog box.

8 Select one of the options under Module SWF Size to enable or disable module optimization. If you select Optimize for Application, Flash Builder compiles the module against the selected application and excludes all classes that are defined in the main application. These can include framework classes or custom classes. When you select this option, you cannot use the same module in another application, because the list of excluded classes might be

different. For more information, see “ Optimize modules in Flash Builder ” on page 191.

Optimize modules in Flash Builder

In Flash Builder, you typically select a single application to optimize the module against when you first create the module or add it to a project. If you later decide to change the application that you optimize the module against, or if do not want to optimize the module, you can edit the module’s properties within the project. For more information, see Reducing module size.

This procedure assumes that the module and application are in the same Flash Builder project. If the modules are in a separate project, manually add the load-externs and link-report compiler options.

1 Right-click the application’s project in the Flex Package Explorer and select Properties. The project’s Properties dialog box appears.

2 In the left pane, select Flex Modules.

3 From the list of modules, select the module and then click the Edit button. The Edit Module dialog box appears.

4 To remove optimization, select Do Not Optimize under Module SWF Size.

5 To optimize the module for a different application, select the new application from the Optimize For Application pop-up menu.

6 Click OK.

To further optimize a module’s file size, you can remove debugging information. If you build a module in Flash

Builder, debugging information is included in the module by default. By removing debugging information, you can further reduce the size of the module. For instructions on how to remove debugging information from modules, see

“ Debug modules in Flash Builder ” on page 191.

Debug modules in Flash Builder

To debug modules and applications, include debug information in the SWF files when they are compiled. To do this in Flash Builder, run the application, because debug information is included by default. On the command line, you set the debug compiler option to true . The default is true , but if you disabled it in a configuration file, make sure to override it.

By default, Flash Builder builds a single SWF file that includes debug symbols, so both Run and Debug work when you execute an application that uses modules in Flash Builder. However, including debug symbols in a module’s SWF file makes the SWF file larger. To exclude debug symbols before deployment, disable debugging for the application’s modules. To do so, export the release version of the modules by selecting Project > Export Release Build.

To exclude debugging information from SWF files in Flash Builder, you can either set the debug option to false in the Additional Compiler Arguments text box, or you can output the SWF files by using the Export Release Build feature, which generates non-debug SWF files. This includes the modules, if those modules are in the current project.

If you create a separate project for your modules, you can enable or disable debugging for the entire project, without changing the settings of your main application.

When you want to debug a module, you must also debug the application that loads the module. The Flex debugger does not connect to an application that does not contain debug information, even if the modules that the application loads contain that information. In other words, you cannot exclude debug information from the application if you want to debug the module that the application loads.

Integrate Flex with HTML applications

You use the Create Ajax Bridge feature to generate JavaScript code and an HTML wrapper file that let you easily use an application built in Flex from JavaScript in an HTML page. This feature works with the Flex Ajax Bridge JavaScript library, which lets you expose an application to scripting in the web browser. The generated JavaScript code is lightweight, as it is intended to expose the functionality that the Flex Ajax Bridge already provides. For more information about the Flex Ajax Bridge, see Flex Ajax Bridge.

The Create Ajax Bridge feature generates JavaScript proxy code that is specific to the application APIs that you want to call from JavaScript. You can generate code for any MXML application or ActionScript class in a Flash Builder project.

For MXML application files, you can generate code for any or all of the following items in the MXML code:

• List of inherited elements, which can expand non-recursively

• Public properties, including tags with id properties

• Public constants

• Public functions, including classes defined in line

For ActionScript classes, you can generate code for any or all of the following items:

• List of inherited elements

• Public properties; for each property, a get and set method is displayed

• Public constants

• Public methods

In a directory that you specify, the Create Ajax Bridge feature generates *.js and *.html files that correspond to the

MXML applications and ActionScript classes that you select for generation. It places a copy of the Flex Ajax Bridge library (fabridge.js) in a subdirectory of the code generation directory. This feature also generates MXML helper files in the project’s src directory; these files are used to complete the JavaScript code generation.

Generate Ajax Bridge code

1 Right-click a project in the Flex Package Explorer and select Create Ajax Bridge.

2 In the Create Ajax Bridge dialog box, select the MXML applications and ActionScript classes for which you want to generate JavaScript code. You can select the top-level check box to include the entire object, or you can select specific members.

3 Specify the directory in which to generate proxy classes.

Chapter 9: Develop Mobile Applications in

Flash Builder

Flash Builder 4.7 provides features to support application development for mobile devices. The mobile features in

Flash Builder make it as easy to develop an ActionScript- or Flex-based mobile application as it is to develop a desktop or web application.

Important: You can write application code, test, and debug mobile applications using Flash Builder 4.7. If you want to design your mobile interface using the design workflows in Flash Builder, use Flash Builder 4.6. For more information on using the design workflows in Flash Builder 4.6, see Developing Mobile Applications with Flex and Flash Builder 4.6

.

Differences in mobile, desktop, and browser application development

Browser Deploys the application as a SWF file for use in Flash Player running in a browser.

Desktop Deploys a stand-alone Adobe AIR application for a desktop computer, such as a Windows computer or

Macintosh.

Mobile Deploys a stand-alone Adobe AIR application for a mobile device, such as a phone or a tablet.

The Flash Player and Adobe AIR runtimes are similar. You can perform most of the same operations in either runtime.

Besides allowing you to deploy stand-alone applications outside a browser, Adobe AIR provides close integration with the host platform. This integration enables such features as access to the file system of the device, the ability to create and work with local SQL databases, and more.

Restrictions on using Spark and MX components in a mobile application

Use the Spark component set when creating mobile applications in Flex. The Spark components are defined in the spark.components.* packages. However, for performance reasons or because not all Spark components have skins for the Mobile theme, mobile applications do not support the entire Spark component set.

Except for the MX charting controls and the MX Spacer control, mobile applications do not support the MX component set defined in the mx.* packages .

The following table lists the components that you can use, that you cannot use, or that require care to use in a mobile application:

Some Spark layout containers, such as

Group and its subclasses, do not have skins. Therefore, you can use them in a mobile application.

Discouraged Skinnable Spark components other than the ones listed above are discouraged because they do not have a skin for the

Mobile theme. If the component does not have a skin for the Mobile theme, you can create one for your application.

Spark DataGrid Spark RichEditableText

No

Notes

Mobile applications do not support MX components, such as the MX Button,

CheckBox, List, or DataGrid. These components correspond to the Flex 3 components in the mx.controls.* and mx.containers.* packages.

Yes Spacer does not use a skin, so it can be used in a mobile application.

Yes, but with performance implications

You can use the MX chart controls, such as the AreaChart and BarChart, in a mobile application. The MX chart controls are in the mx.charts.* packages.

However, performance on a mobile device can be less than optimal depending on the size and type of charting data.

By default, Flash Builder does not include the MX components in the library path of mobile projects. To use the MX charting components in an application, add the mx.swc and charts.swc to your library path.

The following Flex features are not supported in mobile applications:

• No support for drag-and-drop operations

• No support for the ToolTip control

• No support for RSLs

Performance considerations with mobile applications

Owing to the performance constraints of mobile devices, some aspects of mobile application development differ from development for browser and desktop applications. Some performance considerations include the following:

• Write item renderers in ActionScript

For mobile applications, you want list scrolling to have the highest performance possible. Write item renderers in

ActionScript to achieve the highest performance. While you can write item renderers in MXML, your application performance can suffer.

Flex provides two item renderers that are optimized for use in a mobile application: spark.components.LabelItemRenderer and spark.components.IconItemRenderer. For more information on these item renderers, see Using a mobile item renderer with a Spark list-based control.

For more information on creating custom item renderers in ActionScript, see Custom Spark item renderers. For more information on the differences between mobile and desktop item renderers, see Differences between mobile and desktop item renderers.

• Use ActionScript and compiled FXG graphics or bitmaps to develop custom skins

198

Last updated 12/3/2012

USING FLASH BUILDER

Develop Mobile Applications in Flash Builder

The mobile skins shipped with Flex 4.6 are written in ActionScript with compiled FXG graphics to provide the highest performance. You can write skins in MXML, but your application performance can suffer depending on the number of components that use MXML skins. For the highest performance, write skins in ActionScript and use compiled FXG graphics. For more information, see Spark Skinning and FXG and MXML graphics.

• Use text input components that use StageText

When adding text input components such as TextInput and TextArea, use the defaults. These controls use

StageText as the underlying mechanism for text input, which hooks into the native text input classes. This gives you better performance and access to native features such as auto-correction, auto-capitalization, text restriction, and custom soft keyboards.

There are some drawbacks to using StageText including not being able to scroll the view that the controls are in. In addition, you can’t use embedded fonts or use custom sizing for the StageText-based controls. If these are necessary, you can use text input controls based on the TextField class.

• Take care when using MX chart components in a mobile application

You can use the MX chart controls, such as the AreaChart and BarChart controls, in a mobile application. However, they can affect performance depending on the size and type of charting data.

Workflow for creating mobile applications

Create an Android application in Flash Builder

Here is a general workflow for creating a Flex mobile application for the Google Android platform. This workflow assumes that you have already designed your mobile application.

Adobe evangelist Mike Jones shares some lessons learned while developing a multi-platform game Mode by offering ten tips when developing for multiple devices .

Adobe AIR requirements

Flex mobile projects and ActionScript mobile projects require Adobe AIR 2.6 or a higher version. You can run mobile projects on physical devices that support Adobe AIR 2.6 or a higher version of Adobe AIR.

You can install Adobe AIR 2.6 or a higher version only on supported Android devices that run Android 2.2 or a higher version. For the complete list of supported Android devices, see Certified Devices . Also, review the minimum system requirements to run Adobe AIR on Android devices at Mobile System Requirements .

Note: If you do not have a device that supports Adobe AIR 2.6 or a higher version of Adobe AIR, you can use Flash Builder to launch and debug mobile applications on the desktop.

Each version of the Flex SDK includes the required Adobe AIR version. If you have installed mobile applications on a device from an earlier version of the Flex SDK, uninstall Adobe AIR from the device. Flash Builder installs the correct version of Adobe AIR when you run or debug a mobile application on a device.

Create an application

1

A Flex Mobile Project is a special type of Adobe AIR project. Follow the prompts in the new project wizard as you

would for any other Adobe AIR project in Flash Builder. For more information, see “ Flex mobile projects ” on page 58.

To set Android-specific mobile preferences, see “ Set mobile project preferences ” on page 204.

When you create a Flex Mobile Project, Flash Builder generates the following files for the project:

• ProjectName.mxml

The default application file for the project.

By default, Flash Builder names this file with the same name as the project. If the project name contains illegal

ActionScript characters, Flash Builder names this file Main.mxml. This MXML file contains the base Spark application tag for the project. The base Spark application tag can be ViewNavigatorApplication or

TabbedViewNavigatorApplication.

Typically, you do not add content to the default application file directly, other than ActionBar content that is displayed in all views. To add content to the ActionBar, set the navigatorContent , titleContent , or actionContent properties.

• ProjectNameHomeView.mxml

The file representing the initial view for the project. Flash Builder places the file in a views package. The firstView attribute of the ViewNavigatorApplication tag in ProjectName.mxml

specifies this file as the default opening view of the application.

You can also create an ActionScript-only mobile project. See “ Create ActionScript mobile projects ” on page 60.

2 Lay out the content of the initial view of your application.

You can also add any other views that you want to include in your application.

Use the code editor in Flash Builder to add components to a view.

Only use components that Flex supports for mobile development. For more information, see “ Restrictions on using

Spark and MX components in a mobile application ” on page 196.

3 (Optional) Add mobile-optimized item renderers for List components.

Adobe provides IconItemRenderer, an ActionScript-based item renderer for use with mobile applications.

4 Configure launch configurations to run and debug the application.

You can run or debug the application on the desktop or on a device.

A launch configuration is required to run or debug an application from Flash Builder. The first time you run or debug a mobile application, Flash Builder prompts you to configure a launch configuration.

When running or debugging a mobile application on a device, Flash Builder installs the application on the device.

See “ Test and debug a mobile application on a device ” on page 218.

5 Export the application as an installer package.

Use Export Release Build to create packages that can be installed on mobile devices. Flash Builder creates packages

for platform you select for export. See “ Export Android APK packages for release ” on page 224.

Development environment

Building an application for a mobile device is not just a matter of scaling down a desktop application to a different screen size. You create separate user interfaces appropriate for each form factor, while sharing underlying model and data access code among mobile, browser, and desktop projects.

Use native extensions

Native extensions let you include native platform capabilities into your mobile application.

A native extension contains ActionScript classes and native code. Native code implementation lets you access devicespecific features, which cannot be accessed using pure ActionScript classes. For example, accessing the device's vibration functionality.

Native code implementation can be defined as the code that executes outside the Adobe AIR runtime. You define platform-specific ActionScript classes and native code implementation in the extension. The ActionScript extension classes access and exchange data with the native code using the ActionScript class ExtensionContext.

Extensions are specific to a device's hardware platform. You can create platform-specific extensions or you can create a single extension that targets multiple platforms. For example, you can create a native extension that targets both

Android and iOS platforms. The following mobile devices support native extensions:

• Android devices running Android 2.2 or a later version

• iOS devices running iOS 4.0 or a later version

For detailed information on creating cross-platform native extensions, see Developing Native Extensions for Adobe AIR .

For a collection of native extension samples, contributed by Adobe and the community, see Native extensions for

Adobe AIR .

Package native extensions

To provide your native extension to application developers, you package all the necessary files into an ActionScript

Native Extension (ANE) file by following these steps:

1 Build the extension’s ActionScript library into a SWC file.

2 Build the extension’s native libraries. If the extension has to support multiple platforms, build one library for each target platform.

3 Create a signed certificate for your extension. If the extension is not signed, Flash Builder displays a warning when you add the extension to your project.

4 Create an extension descriptor file.

Last updated 12/3/2012

USING FLASH BUILDER

Develop Mobile Applications in Flash Builder

5 Include any external resources for the extension, such as images.

6 Create the extension package using the Air Developer Tool. For more information, see the Adobe AIR documentation .

For detailed information on packaging ActionScript extensions, see Developing Native Extensions for Adobe AIR .

Add native extensions to a project

You include an ActionScript Native Extension (ANE) file in the project’s build path the same way as you would include a SWC file.

1 In Flash Builder, when you create a Flex mobile project, select the Native Extensions tab in the Build Paths settings page.

You can also add extensions from the Project Properties dialog box by selecting Flex Build Path.

2 Browse to the ANE file or the folder containing the ANE files to add to the project. When you add an ANE file, the extension ID is added to the project’s application descriptor file (project name-app.xml) by default.

Flash Builder displays an error symbol for the added extension in the following scenarios:

• The Adobe AIR runtime version of the extension is later than the application’s runtime version.

• The extension does not include all the selected platforms that the application is targeting.

Note: You can create an ActionScript native extension that targets multiple platforms. To test an application that includes this ANE file on your development computer using the Adobe AIR Simulator, ensure that the ANE file supports the computer’s platform. For example, to test the application using the Adobe AIR Simulator on Windows, ensure that the ANE file supports Windows.

Include ActionScript native extensions in an application package

When you use the Export Release Build feature to export the mobile application, the extensions used in the project are included within the application package by default.

To change the default selection, follow these steps:

1 In the Export Release Build dialog box, select the Native Extensions tab under Package Settings.

2 The ActionScript native extension files referenced in your project are listed, indicating if the ANE file is used in the project or not.

If the ANE file is used in the project, it is selected by default in the application package.

If the ANE file is included in the project but not used, the compiler does not recognize the ANE file. It is then not included in the application package. To include the ANE file in the application package, do the following: a In the Project Properties dialog box, select Flex Build Packaging and the required platform.

b Select the extensions that you want to include in the application package.

Configure an iOS SDK externally

The Adobe AIR SDK contains a bundled iOS SDK version. The bundled iOS SDK version is specific to the Adobe AIR version. For example, Adobe AIR 3.1 contains iOS4 SDK, and Adobe AIR 3.4 contains iOS5 SDK.

If you want to use features from an iOS SDK higher than the bundled version, you can configure the supported iOS

SDK version externally.

The supported iOS SDK versions are as follows:

203

Last updated 12/3/2012

USING FLASH BUILDER

Develop Mobile Applications in Flash Builder

Adobe AIR version

AIR 3.1

AIR 3.4

Bundled iOS SDK version iOS4 iOS5 iOS SDK version supported for external configuration iOS5

IOS6

You can configure an iOS SDK by using the AIR Developer Tool (ADT). Flash Builder lets you select the location of the supported external iOS SDK using the Package Settings dialog. After you select the location of the iOS SDK, the selected location is passed through the -platformsdk ADT command.

Note: With Adobe AIR 3.1, you can configure an external iOS SDK only on Mac. With Adobe AIR 3.4, you can configure it both on Windows and Mac.

Hide ANE Library Symbols

When you use multiple native extensions in your iOS application, there can be common symbol names that are used among the native extensions. These symbol name conflicts can cause issues during packaging (error message appears).

And in some cases, cause the application to crash during runtime.

To ensure that this error does not occur, follow these steps:

1 In the Project Properties dialog, select Build Packaging > Apple iOS.

2 Under the Native Extensions tab, select Hide ANE-Library-Symbols.

When you select this option, the ADT package command -hideAneLibSymbols is set to yes , and any unintended symbol conflict issues are resolved. For more information, see ADT package command .

Verify if symbol conflict issues are causing the application to crash

Not all application crashes are caused due to symbol conflict issues. To determine if the crash was caused only due to duplicate symbols in the object files, package the application from the command line using the ADT -package command. Then, review the warning, if it appears.

Note: If the IPA is created successfully, Flash Builder does not show any warnings even if the packager has identified warnings. To review the warnings that appear during packaging, you must package the application from the command line.

To get the command line details, follow these steps:

1 Click Customize Launch in the Run/Debug configurations dialog box or in the Package Settings section of the

Export Release Build dialog box.

2 In the Customize The Launch Parameters dialog, select Show Command.

Set mobile project preferences

Set device configurations

Flash Builder uses device configurations to display device screen size previews on the desktop using the AIR Debug

Launcher (ADL). See “ Test and debug a mobile application on the desktop ” on page 217.

To set device configurations, open Preferences and select Flash Builder > Device Configurations.

Flash Builder provides several default device configurations. You can add, edit, or remove additional device configurations. You cannot modify the default configurations that Flash Builder provides.

Clicking the Restore Defaults button restores default device configurations but does not remove any configurations that you have added. Also, if you added a device configuration with a name that matches one of the defaults, Flash

Builder overrides the added configuration with the default settings.

Device configurations contain the following properties:

Description

A unique name for the device.

Device platform. Select a platform from the list of supported platforms.

Width and height of the device’s screen.

The standard size of an application on the device. This size is the expected size of an application launched in non-full screen mode, accounting for system chrome, such as the status bar.

Pixels per inch on the device’s screen.

Choose target platforms

Flash Builder supports target platforms based on the application type.

To select a platform, open Preferences and select Flash Builder > Target Platforms.

For all third-party plug-ins, see the associated documentation.

Choose an application template

When you create a mobile application, you can select from the following application templates:

Blank Uses the Spark Application tag as the base application element.

Use this option if you want to create a custom application without using the standard view navigation.

View-Based Application Uses the Spark ViewNavigatorApplication tag as the base application element to create an application with a single view.

You can specify the name of the initial view.

Tabbed Application Uses the Spark TabbedViewNavigatorApplication tag as the base application element to create a tab-based application.

To add a tab, enter a name for the tab, and click Add. You can change the order of the tabs by clicking Up and Down.

To remove a tab from the application, select a tab and click Remove.

The name of the view is the tab name with "View" appended. For example, if you name a tab as FirstTab, Flash Builder generates a view named FirstTabView.

For each tab that you create, a new MXML file is generated in the "views" package.

Note: The package name is not configurable through the Flex Mobile Project wizard.

The MXML files are generated according to the following rules:

• If the tab name is a valid ActionScript class name, Flash Builder generates the MXML file using the tab name with

"View" appended.

• If the tab name is not a valid class name, Flash Builder modifies the tab name by removing invalid characters and inserting valid starting characters. If the modified name is unacceptable, Flash Builder changes the MXML filename to "ViewN", where N is the position of the view, starting with N=1.

When you create a mobile application, you can specify or change the default permissions for a target platform. The permissions are specified at the time of compiling, and they cannot be changed at runtime.

First select the target platform, and then set the permissions for each platform, as required. You can edit the permissions later in the application descriptor XML file.

Third-party plug-ins provide additional platform support for both Flex and ActionScript projects. For platformspecific permissions, see the device's associated documentation.

Permissions for the Google Android platform

For the Google Android platform, you can set the following permissions:

INTERNET Allows network requests and remote debugging

The INTERNET permission is selected by default. If you deselect this permission, you cannot debug your application on a device.

WRITE_EXTERNAL_STORAGE Allows writing to an external device

Select this permission to let the application write to an external memory card on the device.

READ_PHONE_STATE Mutes the audio during an incoming call

Select this permission to let the application mute the audio during phone calls. For example, you can select this permission if your application plays audio in the background.

ACCESS_FINE_LOCATION Allows access to a GPS location

Select this permission to let the application access GPS data using the Geolocation class.

DISABLE_KEYGUARD and WAKE_LOCK Disallows sleep mode on the device

Select this permission to prevent the device from going to sleep using the SystemIdleMode class settings.

CAMERA Allows access to a camera

Select this permission to let the application access a camera.

RECORD_AUDIO Allows access to a microphone

Select this permission to let the application access a microphone.

ACCESS_NETWORK_STATE and ACCESS_WIFI_STATE Allows access to information about network interfaces associated with the device

Select this permission to let the application access network information using the NetworkInfo class.

For more information about setting mobile application properties, see the Adobe AIR documentation .

Permissions for the Apple iOS platform

The Apple iOS platform uses runtime validation for permissions instead of predefined permissions. That is, if an application wants to access a specific feature of the Apple iOS platform that requires user permission, a pop-up window appears requesting permission.

Full Screen Displays your application in fullscreen mode on the device. When this setting is enabled, the device’s status bar does not appear above your application. Your application fills the entire screen.

If you want to target your application across multiple device types with varying screen densities, select Automatically

Scale Application For Different Screen Densities. Selecting this option automatically scales the application and handles

density changes, as required, for the device. See “ Set application scaling ” on page 207.

Set application scaling

You use mobile application scaling to build a single mobile application that is compatible with devices with different screen sizes and densities.

Mobile device screens have varying screen densities, or DPI (dots per inch). You can specify the DPI value as 160, 240, or 320, depending on the screen density of the target device. When you enable automatic scaling, Flex optimizes the way it displays the application for the screen density of each device.

For example, suppose that you specify the target DPI value as 160 and enable automatic scaling. When you run the application on a device with a DPI value of 320, Flex automatically scales the application by a factor of 2. That is, Flex magnifies everything by 200%.

To specify the target DPI value, set it as the applicationDPI property of the <s:ViewNavigatorApplication> tag or <s:TabbedViewNavigatorApplication> tag in the main application file:

<s:ViewNavigatorApplication xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" firstView="views.HomeView" applicationDPI="160">

If you choose to not auto-scale your application, you must handle the density changes for your layout manually, as required. However, Flex adapts the skins to the density of each device.

Develop Mobile Applications in Flash Builder

Support for multiple mobile targets

When developing mobile applications for multiple platforms and devices, Flash Builder lets you specify different build configurations for each launch target.

For mobile projects, you can create a custom build target with specific package contents such as native extensions, certificate configurations, and different platform SDKs.

For more information on specifying project properties for a build target, see “ Project properties for packaged mobile projects ” on page 107.

Create a custom build target

1 In the Package Explorer, select the project.

2 Select Project > Properties from the main menu or select Properties from the context menu.

3 In the Project Properties dialog box, select Flex Build Packaging, and select the target platform for which you want to view or change the settings.

4 To create a custom target, click Create Custom, and specify details for the new target. Then, click Create. The target that you create appears in the list of available targets.

5 Specify the digital certificate that you want to use to sign the mobile application, package contents, native extensions, and permissions and entitlements (if applicable).

6 Click OK.

Select a custom target build in the launch configuration

When you specify a launch configuration to run or debug an application, Flash Builder picks up the applicable build target settings by default. For example, say that you created a build target "d1" to run the application on an iOS device.

When you create a launch configuration to debug the application on a simulator, the target build is selected as "d1" by default. You can, however, change the default selection and select a different build target.

Export the application to a custom target

You can export a mobile application to supported custom targets besides the standard supported platforms.

Important: You can use the Export Release Build feature to launch a custom target only on a device.

When you select Project > Export Release Build, all the device-based targets configured for that project appear.

If there is more than one build target for a "device", the target names are displayed in platformname-targetname format. For example, if you have two build targets configured to launch the application on an iOS device, the target names are displayed as AppleiOS-targetname1 and AppleiOS-targetname2 .The created application package name has the matching target name specified.

Example of packaging and exporting an application to multiple build targets

You are developing an application for the Apple iOS platform and you have multiple ActionScript Native Extension

(ANE) files as follows:

• Native extension "n1" for an iOS device (iPhone-ARM)

• Native extension "n2" for the iOS simulator (iPhone-x86)

The native extension "n1" uses iOS4 SDK features and the native extension "n2" uses iOS5 SDK features.

208

Last updated 12/3/2012

USING FLASH BUILDER

Develop Mobile Applications in Flash Builder

While packaging your mobile application, you want to create different application packages for the device and simulator selecting different ANEs in each package, as follows:

• Build target "d1" to launch the application on an iOS device with native extension "n1" selected

• Build target "s1" to launch the application on the iOS simulator with native extension "n2" selected

To do so, follow these steps:

1 In the Project Properties page, select Flex Build Packaging > Apple iOS.

2 Click Create Custom to specify the first build configuration.

3 Specify the Build Target Name as "d1", select the Build Target Base as "device", and click Create.

4 Click Apply.

5 Again, click Create Custom to specify the second build configuration.

6 Specify the Build Target Name as "s1", select the Build Target Base as "simulator", and click Create.

7 The custom targets that you created appear in the list of available targets.

8 To select the required native extensions while exporting the application, follow these steps:

• Select the target as d1 [device], and the native extension "n1" from the Native Extensions section. Click Apply.

• Select the target as s1 [simulator], and the native extension "n2" from the Native Extensions section. Click Apply.

9 Click OK.

You can export the application to multiple build targets by following these steps:

1 Select Project > Export Release Build.

2 In the Export Release Build dialog box, the custom targets that you created appear as "Apple iOS-d1" and "Apple iOS-s1". You can select multiple targets to export your application to.

3 For each selected target platform, you can specify the native extension to use, the digital certificate to sign the application, and package contents.

Note: The native extensions used in the project are included within the application package by default. You can,

however, change the default selection if necessary. For more information, see “ Include ActionScript native extensions in an application package ” on page

4 Before exporting the application, you can add or edit the launch parameter values like -target, -keystore, and such.

Click Customize Launch to customize the launch parameter values.

5 Click Finish.

Customize launch parameters

Flash Builder lets you view and edit launch parameters before you launch, debug, or export an application.

Flash Builder calculates the launch parameter values internally, and lets you add, delete, or modify the values, as required, using the Customize Launch Parameters dialog.

Flash Builder also lets you view the command details for the launch parameters for mobile application packaging by clicking Show Command in the Customize Launch Parameters dialog.

You can access the Customize Launch Parameters dialog from the Run/Debug Configurations dialog, Export Release

Build dialog, or the Build Packaging Properties dialog.

Note: In the Build Packaging Properties dialog, you can only view the parameters but not its values. You can, however, edit the parameter values.

USING FLASH BUILDER

Develop Mobile Applications in Flash Builder

Customize ADL and ADT parameter values

You can customize parameter values before packaging the application using the AIR Developer Tool (ADT) and before launching the application using the AIR Debug Launcher (ADL).

When you launch or debug an application, you can:

• edit customizable parameter values,

• add new packaging content,

• add a parameter, or,

• delete an existing parameter by providing an empty value.

Customizable parameter values are values that you have configured or values that Flash Builder calculates internally.

Note: For ADL and export release of non-mobile package types, adding of new parameters is not supported.

To edit a parameter value, follow these steps:

1 Click Customize Launch in the Run/Debug configurations dialog box.

2 Click Edit in the Customize Launch Parameters dialog box.

3 Select the parameter values that you want to edit. You can choose to add the customized value at the end of or before a particular argument. Flash Builder accepts the customized values only after validating it. For example, Flash

Builder does not allow an empty parameter value.

It is recommended that you create separate build targets for launching on the desktop and device, and edit the parameters appropriately. The customized values are persisted for the selected build target and build name.

Example

<buildTarget airDownloadURL="" androidSettingsVersion="2" buildTargetName="device" isCurrent="true" platformId="com.adobe.flexide.multiplatform.android.platform">

<newPackagingParams>

<Parameter location="placeAtEnd" name="-sfsfgfd" value="sdfdgdg"/>

</newPackagingParams>.

</buildTarget>

Note: When a project is created, these values are not specified in the project settings. These values are added to the project settings only if they are applicable.

There are various scenarios, like the following, where you can customize the launch parameter values:

Enabling profiling with Adobe Scout for iOS packages

To configure your IPA package for profiling using Adobe® Scout (formerly codenamed Project "Monocle"), specify a new ADT parameter while creating the IPA file.

To do so, follow these steps:

1 Click Customize Launch in the Run/Debug configurations dialog box or Export Release Build dialog box.

Note: While launching or debugging the application, ensure that you select the launch method as "on device".

2 Click Add Parameter in the Customize Launch Parameters dialog box.

3 Specify the parameter name as -sampler.

and the location as Place Before -provisioning-profile .

210

Last updated 12/3/2012

USING FLASH BUILDER

Develop Mobile Applications in Flash Builder

The values that you specify for a build target are used across different packaging scenarios. If you, however, want to specify different parameter values for the Run/Debug Configurations dialog and for the Export Release Build dialog,

create multiple build targets. For more information, see “ Support for multiple mobile targets ” on page 208.

Launching ANEs with Symlink using ADL

When you use the AIR Debug Launcher (ADL) to launch an application with ANEs, Flash Builder automatically extracts the ANEs to a directory using the -extDir command; Flash Builder does the extraction in the background.

If the ANE, however, contains symlinks, Flash Builder cannot extract the ANEs automatically, and hence the ADL launch fails. To avoid the ADL launch failure, manually extract the ANE files to a folder on your computer and specify the fully qualified path to the folder as the value for the -extDir parameter.

For example, if you extract the ANE files to /User/myname/myanepath, edit the --extDir parameter as follows:

1 Click Customize Launch in the Run/Debug configurations dialog box.

2 Click Edit in the Customize Launch Parameters dialog box.

3 Select -extDir and specify the parameter value with the fully qualified path to the folder:

/User/myname/myanepath.

The value that you specify for -extDir overwrites any value that Flash Builder calculates internally.

Add new packaging content

While exporting an application package, you can add a file to the package by following these steps:

1 Click Customize Launch in the Package Settings section of the Export Release Build dialog box.

2 Click Add File To Package, and specify the fully qualified path to the file that you want to add to the package.

Connect Google Android devices

You can connect a Google Android device to your development computer to preview or debug the application on the

Android device.

Supported Android devices

Flex mobile projects and ActionScript mobile projects require Adobe AIR 2.6 or a higher version of Adobe AIR. You can run or debug mobile projects only on physical devices that support Adobe AIR 2.6 or a higher version.

You can install Adobe AIR 2.6 on supported Android devices running Android 2.2 or a higher version. For a list of supported devices, see http://www.adobe.com/flashplatform/certified_devices/ .

Prepare to build, debug, or deploy an iOS application

Before you build an iOS application using Flash Builder and deploy the application on an iOS device or submit to the

Apple App store, follow these steps:

1 Join the Apple iOS Developer Program .

You can log in using your existing Apple ID or create an Apple ID. The Apple Developer Registration guides you through the necessary steps.

2 Register the Unique Device Identifier (UDID) of the device.

This step is applicable only if you are deploying your application to an iOS device and not the Apple App Store. If you want to deploy your application on several iOS devices, register the UDID of each device.

Obtain the UDID of your iOS device a Connect the iOS device to your development computer and launch iTunes. The connected iOS device appears under the Devices section in iTunes.

b Click the device name to display a summary of the iOS device.

c In the Summary tab, click Serial Number to display the 40-character UDID of the iOS device.

h Select the CSR file and click Submit.

On the Certificates page, click Download.

Save the downloaded file (*.distribution_identity.cer).

5 Convert the iOS developer certificate or the iOS distribution certificate to a P12 file format (*.p12).

You convert the iOS developer or iOS distribution certificate to a P12 format so that Flash Builder can digitally sign your iOS application. Converting to a P12 format combines your iOS developer/distribution certificate and the associated private key into a single file.

Note: If you are testing the application on the desktop using the AIR Debug Launcher (ADL), you don’t have to convert the iOS developer/distribution certificate into a P12 format.

Use Keychain Access on Mac or OpenSSL on Windows to generate a Personal Information Exchange (*.p12) file.

For more information, see Convert a developer certificate into a P12 file.

6 Generate the Application ID by following these steps: a Log in to the iOS Provisioning Portal using your Apple ID.

b Go to the App IDs page, and click New App ID.

c In the Manage tab, enter a description for your application, generate a new Bundle Seed ID, and enter a Bundle

Identifier.

Every application has a unique Application ID, which you specify in the application descriptor XML file. An

Application ID consists of a ten-character "Bundle Seed ID" that Apple provides and a "Bundle Identifier" suffix that you specify. The Bundle Identifier you specify must match the application ID in the application descriptor file. For example, if your Application ID is com.myDomain.*, the ID in the application descriptor file must start with com.myDomain.

Important: Wildcard Bundle Identifiers are good for developing and testing iOS applications but can't be used to deploy applications to the Apple App Store.

Testing and debugging

Flash Builder offers options for testing and debugging your mobile application on the device or on the desktop using the AIR Debug Launcher (ADL). In either case, you can use the Flash Builder debugging capabilities, including setting breakpoints and examining the application's state using the Variables and Expressions panels.

Test and debug a mobile application on the desktop

For initial testing or debugging, or if you don’t have a mobile device, Flash Builder lets you test and debug applications on the desktop using the AIR Debug Launcher (ADL).

Before you test or debug a mobile application for the first time, you define a launch configuration. Specify the target

platform and On Desktop as the launch method. See “ Manage launch configurations ” on page 96.

Configure device information for desktop preview

The properties of a device configuration determine how the application appears in the ADL.

“ Set device configurations ” on page 204 lists the supported configurations. Device configurations do not affect the

application’s appearance on the device.

Screen density

Flash Builder uses a screen density of 240 DPI when you preview your application on your development desktop. An application’s appearance during preview sometimes differs from its appearance on a device that supports a different pixel density.

Preview applications with ADL

When you preview applications on the desktop, Flash Builder launches the application using the ADL. The ADL provides a Device menu with corresponding shortcuts to emulate buttons on the device.

For example, to emulate the back button on a device, select Device > Back. Select Device > Rotate Left or Device >

Rotate Right to emulate rotating the device. Rotate options are disabled if you have not selected auto orientation.

Drag in a list to emulate scrolling the list on a device.

Adobe Certified Expert in Flex, Brent Arnold, created a video tutorial on using ADL to preview a mobile application on the desktop .

Test and debug an iOS application on a simulator

The iOS Simulator offers a fast way to run and debug iOS applications without using a device. The iOS simulator can simulate iOS devices, like iPhone and iPad, and different iOS versions.

Important: You use the iOS Simulator to run your iOS application only on a Mac.; the iOS simulator is not supported on Windows.

When testing with the iOS simulator, you do not need a developer certificate or a provisioning profile. However, you must still create a p12 certificate.

Prepare to debug on the iOS simulator

Before you test or debug your application on the iOS simulator, ensure the following:

• The application uses an SDK that contains Adobe AIR 3.4.

217

Last updated 12/3/2012

/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs

4 Click the Default Device drop-down list and select the device that you want to simulate when you debug the application. Any change you make to the default device when the simulator is running is reflected only when you launch the simulator again.

Note: To select a different device when the simulator is running, select Hardware > Device in the iOS simulator, and choose the device.

5 Click Configure Package Settings and select the p12 certificate.

If you don’t have a p12 certificate that Apple has issued, you can create a user-signed certificate. User-signed certificates, however, can be used to launch applications only on the simulator and not on Apple iOS devices.

6 Click Debug to launch the iOS Simulator and debug the application. The application is automatically launched on the iOS simulator by default.

For more information on using the iOS simulator, see Using iOS Simulator .

Test and debug a mobile application on a device

You can use Flash Builder to test or debug a mobile application from your development desktop or from a device.

You test and debug applications based on a launch configuration that you define. Flash Builder shares the launch configuration between running and debugging the application. When you use Flash Builder to debug an application on a device, Flash Builder installs a debug version of the application on the device.

Note: If you export a release build to a device, you install a non-debug version of the application. The non-debug version is not suitable for debugging.

For more information, see “ Create or edit launch configurations to run or debug mobile applications ” on page 97.

Debug an application on a Google Android device

On an Android device, debugging requires Android 2.2 or later.

Develop Mobile Applications in Flash Builder the device before the debugging starts. Ensure that your device is connected to the host machine’s USB port during the entire debugging session.

Debug over a network When you debug an application over the network, the device and the host machine must be on the same network. The device and the host machine can be connected to the network via Wi-Fi, ethernet, or Bluetooth.

When you debug over a network, Flash Builder lets you debug an application that is already installed on a connected device without reinstalling the application. Connect the device to the host machine via a USB port only during packaging and while installing the application on the device. You can unplug the device from the USB port during debugging. However, ensure that there is a network connection between the device and the host machine during the entire debugging session.

Prepare to debug the application

Before you begin debugging over USB or over a network, follow these steps:

1 (Windows) Ensure that the proper USB driver is installed.

On Windows, install the Android USB driver. See the documentation accompanying the Android SDK build for

more information. For more information, see “ Install USB device drivers for Android devices (Windows) ” on page 212.

2 Ensure that USB debugging is enabled on your device.

In device Settings, go to Applications > Development, and enable USB debugging.

Check for connected devices

When you run or debug a mobile application on a device, Flash Builder checks for connected devices. If Flash Builder finds a single connected device online, Flash Builder deploys and launches the application. Otherwise, Flash Builder launches the Choose Device dialog for these scenarios:

• No connected device found

• Single connected device found that is offline or its OS version is not supported

• Multiple connected devices found

If multiple devices are found, the Choose Device dialog lists the devices and their state (online or offline). Select the device to launch.

The Choose Device dialog lists the OS version and the Adobe AIR version. If Adobe AIR is not installed on the device,

Flash Builder installs it automatically.

The first time that you debug the application over a network, you can install the application on the device over

USB. To do so, select Install The Application On The Device Over USB, and connect the device to the host machine via a USB port.

Once the application is installed, if you don’t want to connect over USB for subsequent debugging sessions, deselect Install The Application On The Device Over USB.

• (Optional) Clear application data on each launch.

Select this option if you want to keep the state of the application for each debugging session. This option applies only if sessionCachingEnabled is set to True in your application.

3 Select Debug to begin a debugging session.

The debugger launches and waits for the application to start. The debugging session starts when the debugger establishes a connection with the device.

When you try to debug on a device over a network, the application sometimes displays a dialog requesting an IP address. This dialog indicates that the debugger could not connect. Ensure that the device is properly connected to the network, and that the computer running Flash Builder is accessible from that network.

Note: On a corporate, hotel, or other guest network, sometimes the device cannot connect to the computer, even if the two are on the same network.

If you are debugging via network, and the application was previously installed on the device, start debugging by typing the IP address of the host machine.

USING FLASH BUILDER

Develop Mobile Applications in Flash Builder

Note: You can debug over USB only if you have Adobe AIR SDK 3.4 or higher.

Debug over USB To debug an application over a USB connection, connect the iOS device to the host machine via a

USB port. When you debug over USB, Flash Builder packages the debug iOS package (IPA file) and installs the IPA file on the device. You need to launch the application on the iOS device manually to start the debugging. Ensure that your device is connected to the host machine’s USB port during the entire debugging session.

Debug over a network When you debug an application over the network, the device and the host machine must be on the same network. The device and the host machine can be connected to the network via Wi-Fi, ethernet, or Bluetooth.

Prepare to debug the application

Before you debug an application on an iOS device, ensure that you have a provisioning file from Apple and an Appleissued developer certificate that you need to convert into P12 format. For more information, follow the steps described

in “ Prepare to build, debug, or deploy an iOS application ” on page 214.

To debug an iOS application over USB, ensure that:

• The application uses an SDK that contains Adobe AIR 3.4.

• iTunes is installed on your development computer. iTunes installs the necessary device drivers required for debugging over USB.

Debug the application

1 Connect the Apple iOS device to your development computer.

2 In Flash Builder, select Run > Debug Configurations.

3 In the Debug Configurations dialog, follow these steps: a Select the application that you want to debug.

b Select the target platform as Apple iOS.

c Select the launch method as On Device.

d Select one of the following packaging methods:

Standard Use this method to package a release-quality version of your application that can run on Apple iOS devices. The application performance with this method is similar to the performance of the final release package and can be submitted to the Apple App Store.

However, this method of creating a debug iOS (IPA) file takes several minutes.

Fast Use this method to create an IPA file quickly, and then run and debug the file on the device. This method is suitable for application testing purposes. The application performance with this method is not release quality, and it is not suitable for submission to the Apple App Store. f e Click Configure to select the appropriate code signing certificate, provisioning file, and package contents.

Select Debug Via USB or Debug Via Network.

When you debug over USB, a debug port that is freely available is selected and added to the debug iOS package.

When you debug over the network, click Configure Network Debugging to select the network interface that you want to add in the debug iOS package.

Note: Your host machine can be connected to multiple network interfaces simultaneously. However, you can select a primary network interface to use for debugging.

g Before you begin to debug the application, check if you have previously installed this application on your device.

If so, uninstall the previously installed application.

USING FLASH BUILDER

Develop Mobile Applications in Flash Builder h Click Debug. Flash Builder displays a dialog requesting for a password. Enter your P12 certificate password.

Flash Builder generates the debug IPA file and installs it on the device.

Note: Flash Builder installs the IPA file on the device only if you are using Adobe AIR SDK 3.4 or higher. If you are using an Adobe AIR SDK version lesser than 3.4, you need to use iTunes to install the application on the device. For more information, see this Help topic .

4 Launch the application on the iOS device.

5 Flash Builder attempts connection to the host address specified in the debug IPA file. If the application cannot connect to the host address, Flash Builder displays a dialog requesting the IP address of the host machine.

Note: If you have not changed your code or assets since the last debug IPA package was generated, Flash Builder skips the packaging and debugs the application. That is, you can launch the installed application on your device and click

Debug to connect to the Flash Builder debugger. This way, you can debug repeatedly without packaging the application every time.

Change Application ID while testing or debugging

Every application has a unique Application ID, which you specify in the application descriptor XML file.

When you run or debug an iOS application, you generate an Application ID in the iOS Provisioning Portal. The

Application ID that you generate is based on the Application ID specified in the application descriptor file. For example, if your Application ID is com.myDomain.*, the ID in the application descriptor file must start with com.myDomain. This application ID is used in the provisioning file used for testing or debugging the application. For

more information, see “ Apple iOS development process using Flash Builder ” on page 213.

In general, when you run or debug an application, Flash Builder creates a copy of the application descriptor file and internally modifies the Application ID by adding a .debug extension. For example, if your application ID is com.myDomain, it is modified to com.myDomain.debug. Flash Builder makes this change so that while testing or debugging an application on a device, you don’t replace an installed application with the same name.

This internal change that Flash Builder makes can, however, cause a mismatch between the Application ID specified in the application descriptor XML file and the Application ID specified in the provisioning file. To overcome this mismatch, Flash Builder lets you modify the Application ID as required from the Run/Debug Configurations dialog box. When you change the Application ID for an application file in the project, Flash Builder persists the mapping information and uses it across multiple debugging sessions.

Note: The Application ID appears blank in the Run/Debug Configurations dialog if a bin-debug folder has not yet been created for your project. The value you enter for the Application ID is updated in the Application Descriptor file the next time you launch the application by clicking Run or Debug.

USING FLASH BUILDER

Develop Mobile Applications in Flash Builder

You can use Flash Builder to install an application directly on an Android device. When you install a package on a device on which Adobe AIR is not installed, Flash Builder installs Adobe AIR automatically.

1 Connect the Google Android device to your development computer.

Flash Builder accesses the device connected to your computer’s USB port. Ensure that you have configured the

necessary USB device drivers. See “ Connect Google Android devices ” on page 211.

2 In Flash Builder, select Run > Run Configurations. In the Run Configurations dialog box, select the mobile application that you want to deploy.

3 Select the launch configuration method as On Device.

4 (Optional) Specify whether to clear application data on each launch.

5 Click Apply.

Flash Builder installs and launches the application on your Android device. If you installed the package on a device on which Adobe AIR is not installed, Flash Builder installs Adobe AIR automatically.

Adobe Certified Expert in Flex, Brent Arnold, created a video tutorial on setting up and running your application on an Android device .

Install an application on an Apple iOS device

Important: Before you install an application on an iOS device, you need the Apple iOS development certificate (in P12

format) and a development-version of the provisioning profile. Ensure that you follow the steps described in “ Prepare to build, debug, or deploy an iOS application ” on page

1 Connect the Apple iOS device to your development computer.

2 In Flash Builder, select Run > Run Configurations.

3 In the Run Configurations dialog, follow these steps: a Select the application that you want to install.

b Select the target platform as Apple iOS.

c Select the launch method as On Device.

d Select one of the following packaging methods:

Standard Use this method to package a release-quality version of your application that can run on Apple iOS devices.

The Standard method of packaging translates the bytecode of the application's SWF file into ARM instructions before packaging. Because of this additional translation step before packaging, this method of creating an application (IPA) file takes several minutes. The Standard method takes longer than the Fast method. However, the application performance with the Standard method is release-quality, and it is suitable for submission to the

Apple App Store.

Fast Use this method to create an IPA file quickly.

The Fast method of packaging bypasses the translation of bytecode and just bundles the application SWF file and assets with the pre-compiled Adobe AIR runtime. The Fast method of packaging is quicker than the

Standard method. However, the application performance with the Fast method is not release-quality, and it is not suitable for submission to the Apple App Store.

Note: There are no runtime or functional differences between the Standard and Fast methods of packaging.

4 Launch the application deployed on your iOS device.

224

Packaging and exporting

When your application is ready for deployment, use the Export Release Build process, just as you would to prepare desktop and web applications. The main difference is that when you export a release build of a mobile project, Flash

Builder packages the build as a native installer, not as an .air file. For example, on Android, Flash Builder produces an

.apk file that looks the same as a native Android application package. The native installer enables AIR-based applications to be distributed the same way as native applications on each platform.

Package and export a mobile application to an online store

Use Flash Builder’s Export Release Build feature to package and export the release build of a mobile application. A release build is generally the final version of the application that you want to upload to an online store like, the Android

Market, Amazon Appstore, or Apple’s App store.

When exporting an application, you can choose to install the application on a device. If the device is connected to your computer during export, Flash Builder installs the application on the device. You can also choose to export a platformspecific application package for later installation on a device. The resulting package can be deployed and installed in the same way as a native application.

For detailed information on exporting an Android application to the Android Market or Amazon App Store, see

“ Export Android APK packages for release ” on page 224.

For detailed information on exporting an iOS application to the Apple App store, see “ Export Apple iOS packages for release ” on page 225.

Export the application with captive runtime

When you use the Export Release Build feature to export a mobile application, you can choose to embed the Adobe

AIR runtime within the application package.

Users can then run the application even on a device that does not already have Adobe AIR installed on it. Depending on the platform to which you are exporting the package, you can use a captive runtime or a shared runtime.

Export Android APK packages for release

Before you export a mobile application, you can customize the Android permissions. Customize the settings manually in the application descriptor file. These settings are in the <android> block of the bin-debug/app_name-app.xml file.

For more information, see Setting AIR application properties .

If you export the application for later installation on a device, install the application package using the tools provided by the device’s OS provider.

1 In Flash Builder, select Project > Export Release Build.

2 Select the project and application that you want to export.

Last updated 12/3/2012

USING FLASH BUILDER

Develop Mobile Applications in Flash Builder

3 Select the target platforms and the location to export the project.

4 Export and sign a platform-specific application package.

You can package your application with a digital signature for each target platform or as a digitally signed AIR application for the desktop.

You can also export the application as intermediate AIRI file that can be signed later. If you select that option, use the AIR adt command line tool later to package the AIRI as an APK file. Then install the APK file on the device using platform-specific tools (for example, with the Android SDK, use adb). For information on using command

line tools to package your application, see “ Digitally sign your Adobe AIR applications ” on page 108.

5 On the Packaging Settings page, you can select the digital certificate, package contents, and any native extensions.

Deployment If you also want to install the application on a device, click the Deployment page and select Install And

Launch Application On Any Connected Devices. Ensure that you have connected one or more devices to your computer’s USB ports.

• Export application with captive runtime

Select this option if you want to embed the AIR runtime within the APK file while exporting the application package. Users can then run the application even on a device that does not have AIR already installed on it.

• Export application that uses a shared runtime

Select this option if you do not want to embed the AIR runtime within the APK file while exporting the application package. You can select or specify a URL to download Adobe AIR for the application package if AIR is not already installed on a user’s device.

The default URL points to the Android Market. You can, however, override the default URL and select the URL that points to a location on the Amazon Appstore, or enter your own URL.

Digital Signature Click the Digital Signature tab to create or browse to a digital certificate that represents the application publisher’s identity. You can also specify a password for the selected certificate.

If you create a certificate, the certificate is self-signed. You can obtain a commercially signed certificate from a

certificate provider. See “ Digitally sign your Adobe AIR applications ” on page 108.

Package Contents (Optional) Click the Package Contents tab to specify which files to include in the package.

Native Extensions (Optional) Select the native extensions that you want to include in the application package.

For more information about native extensions, see “ Use native extensions ” on page 202.

6 Click Finish.

Flash Builder creates ApplicationName.apk

in the directory specified in the first panel (the default is the top level of your project). If the device was connected to your computer during export, Flash Builder installs the application on the device.

Export Apple iOS packages for release

You can create and export an iOS package for ad hoc distribution or for submission to the Apple App Store.

Important: Before exporting an iOS package, ensure that you obtain the required certificates and a distribution

provisioning profile from Apple. To do so, follow the steps described in “ Prepare to build, debug, or deploy an iOS application ” on page

1 In Flash Builder, select Project > Export Release Build.

2 Select Apple iOS as the target platform to export and sign an IPA package.

3 On the Packaging Settings page, you can select the provisioning certificate, digital certificate, package contents, and any native extensions.

Deployment When you export an iOS package, the AIR runtime is embedded within the IPA file by default.

Digital Signature Select the P12 certificate and the distribution provisioning profile that you obtained from Apple.

You can select one of the following package types:

• Ad Hoc Distribution For Limited Distribution For a limited distribution of the application

• Final Release Package For Apple App Store To submit the application to the Apple App Store

Package Contents (Optional) Click the Package Contents tab to specify which files to include in the package.

Native Extensions (Optional) Select the native extensions that you want to include in the application package.

If the native extension uses iOS5 SDK features, select the location of the iOS SDK. For more information, see

“ Configure an iOS SDK externally ” on page 203.

4 Click Finish.

Flash Builder validates the configuration of the package settings and then compiles the application. Once the packaging is complete, you can install the IPA file on a connected Apple iOS device or submit to the Apple App

Store.

To package the IPA file using the AIR Developer Tool (ADT), see iOS packages in Building AIR Applications.

Create, test, and deploy using the command line

You can create a mobile application without Flash Builder. You use the mxmlc, adl, and adt command line tools instead.

Here is the general process for developing and installing a mobile application on a device using command line tools.

Each of these steps is described in more detail later:

1 Compile the application with the mxmlc tool.

mxmlc +configname=airmobile MyMobileApp.mxml

This step requires that you pass the configname parameter set to “airmobile”.

2 Test the application in AIR Debug Launcher (ADL) with the adl tool.

adl MyMobileApp-app.xml -profile mobileDevice

This step requires that you create an application descriptor file and pass it as an argument to the adl tool. You also specify the mobileDevice profile.

3 Package the application using the adt tool.

adt -package -target apk SIGN_OPTIONS MyMobileApp.apk MyMobileApp-app.xml MyMobileApp.swf

This step requires that you first create a certificate.

4 Install the application on your mobile device. To install your application on an Android device, you use the adb tool.

adb install -r MyMobileApp.apk

This step requires that you first connect your mobile device to your computer via USB.

5 Deploy the mobile application to online stores.

Compile a mobile application with mxmlc

You can compile mobile applications with the mxmlc command-line compiler. To use mxmlc, pass the configname parameter the value airmobile ; for example: mxmlc +configname=airmobile MyMobileApp.mxml

By passing +configname=airmobile , you instruct the compiler to use the airmobile-config.xml file. This file is in the sdk/frameworks directory. This file performs the following tasks:

• Applies the mobile.swc theme.

• Makes the following library path changes:

• Removes libs/air from the library path. Mobile applications do not support the Window and

WindowedApplication classes.

• Removes libs/mx from the library path. Mobile applications do not support MX components (other than charts).

• Adds libs/mobile to the library path.

• Removes the ns.adobe.com/flex/mx and www.adobe.com/2006/mxml namespaces. Mobile applications do not support MX components (other than charts).

• Disables accessibility.

• Removes RSL entries; mobile applications do not support RSLs.

The mxmlc compiler generates a SWF file.

Test a mobile application with adl

You can use AIR Debug Launcher (ADL) to test a mobile application. You use ADL to run and test an application without having to first package and install it on a device.

Debug with the adl tool

ADL prints trace statements and runtime errors to the standard output, but does not support breakpoints or other debugging features. You can use an integrated development environment such as Flash Builder for complex debugging issues.

Launch the adl tool

To launch the adl tool from the command line, pass your mobile application’s application descriptor file and set the profile parameter to mobileDevice , as the following example shows: adl MyMobileApp-app.xml -profile mobileDevice

The mobileDevice profile defines a set of capabilities for applications that are installed on mobile devices. For specific information about the mobileDevice profile, see Capabilities of different profiles .

Create an application descriptor

If you did not use Flash Builder to compile your application, you create the application descriptor file manually. You can use the /sdk/samples/descriptor-sample.xml file as a base. In general, at a minimum, make the following changes:

• Point the <initialWindow><content> element to the name of your mobile application’s SWF file:

<initialWindow>

<content>MyMobileApp.swf</content>

...

</initialWindow>

• Change the title of the application, because that is how it appears under the application’s icon on your mobile device. To change the title, edit the <name><text> element:

<name>

<text xml:lang="en">MyMobileApp by Nick Danger</text>

</name>

• Add an <android> block to set Android-specific permissions for the application. Depending on what services your device uses, you can often use the following permission:

<application>

...

<android>

<manifestAdditions>

<![CDATA[<manifest>

<uses-permission android:name="android.permission.INTERNET"/>

</manifest>]]>

</manifestAdditions>

</android>

</application>

You can also use the descriptor file to set the height and width of the application, the location of icon files, versioning information, and other details about the installation location.

For more information about creating and editing application descriptor files, see AIR application descriptor files .

Package a mobile application with adt

You use AIR Developer Tool (ADT) to package mobile applications on the command line. The adt tool can create an

APK file that you can deploy to a mobile Android device.

Create a certificate

Before you can create an APK file, create a certificate. For development purposes, you can use a self-signed certificate.

You can create a self-signed certificate with the adt tool, as the following example shows: adt -certificate -cn SelfSign -ou QE -o "Example" -c US 2048-RSA newcert.p12 password

The adt tool creates the newcert.p12 file in the current directory. You pass this certificate to adt when you package your application. Do not use self-signed certificates for production applications. They only provide limited assurance to users. For information on signing your AIR installation files with a certificate issued by a recognized certification authority, see Signing AIR applications .

Create the package file

To create the APK file for Android, pass the details about the application to the adt tool, including the certificate, as the following example shows: adt -package -target apk -storetype pkcs12 -keystore newcert.p12 -keypass password

MyMobileApp.apk MyMobileApp-app.xml MyMobileApp.swf

The output of the adt tool is an appname.apk file.

Package for iOS

To package mobile applications for iOS, you must get a developer certificate from Apple, as well as a provisioning file.

This requires that you join Apple’s developer program. For more information, see “ Prepare to build, debug, or deploy an iOS application ” on page 214.

Flex evangelist Piotr Walczyszyn explains how to package the application with ADT using Ant for iOS devices.

Install a mobile application on a device with adb

You use Android Debug Bridge (adb) to install the application (APK file) on a mobile device running Android. The adb tool is part of the Android SDK.

Connect the device to a computer

Before you can run adb to install the APK file on your mobile device, connect the device to your computer. On

Windows and Linux systems, connecting a device requires the USB drivers.

For information on installing USB drivers for your device, see Using Hardware Devices .

Install the application on a connected device

After you connect the device to your computer, you can install the application to the device. To install the application with the adb tool, use the install option and pass the name of your APK file, as the following example shows: adb install -r MyMobileApp.apk

Use the -r option to overwrite the application if you have previously installed it. Otherwise, you must uninstall the application each time you want to install a newer version to the mobile device.

Retain bin-release-temp folder and dSYM folder

When you export a package for release, Flash Builder creates the release-quality SWF file, the application descriptor xml file, and the required package contents in the bin-release-temp folder of your project. After exporting the package,

Flash Builder deletes the contents in the bin-release-temp folder by default.

If you want to retain the contents of the folder and disallow Flash Builder from deleting it, select Keep Bin-Release-

Temp Folder in the Export Release Build dialog box. You need to explicitly make this selection every time you want to retain the contents of the bin-release-temp folder while exporting.

Retain *.dSYM folder

When you export an Apple iOS package (IPA) with native extensions on a Mac, the AOT (ahead-of-time) compiler creates a folder (with a *.dSYM extension). The *.dSYM folder is created in AOT/*.dSYM within the bin-release-temp folder. To retain the *.dSYM folder and disallow Flash Builder from deleting it by default, select Keep Bin-Release-

Temp Folder in the Export Release Build dialog box.

Note: When you run or debug an iOS package application, a *.dSYM folder is created in AOT/*.dSYM within the bindebug folder. This folder contains the required files to debug native extensions on a Mac. Flash Builder retains this folder by default.

2 Expand the Basic, CVS, Debug, Text Compare, or View and Editor Folders categories to locate and select the font and colors to change.

Note: You can also click Use System Font instead of Change to set the font to a reasonable value that the operating system chooses. For example, in Windows, selecting this option causes Flash Builder to use the font selected in the

Windows Display Properties control panel.

3 Set the font and color preferences as desired.

Control single and double-click behavior

You can control how the workbench responds to single and double-clicks.

1 Open the Preferences dialog and select General.

2 In the Open Mode section, make your selections and click OK.

Set workbench preferences

You can set preferences for many aspects of the workbench. For example, you can specify that Flash Builder prompts you for the workspace you want to use at startup, you can select which editor to use when opening certain types of resources, and you can set various options for running and debugging your applications.

Your Flash Builder preferences apply to the current workspace only. You can, however, export your workbench preferences and then import them into another workspace. This may be helpful if you are using multiple workspaces, or if you want to share your workbench preferences with other members of your development team.

You can also set preferences for individual projects within a workspace. For example, you can set separate compiler or debugging options for each of your Flex projects.

Warn before upgrading old Flash Builder projects

Flash Builder updates projects that were created with an earlier version of Flash Builder. Flash Builder updates the project files and structure to conform to the current structure of Flash Builder projects. A converted project is no longer accessible under the earlier version of Flash Builder.

By default, Flash Builder warns you before making the conversion. Disable this option if you want conversions to happen silently.

Data/Services

The following user preferences are available for Data/Services. These preferences apply to all projects in your Flash

Builder developer environment.

You can override these preferences on a project basis. Select Project > Properties > Data/Services to override the preferences specified here.

Code Generator

Flash Builder provides a default code generation utility for generating access to data services. Using Flash Builder extensibility features, you can create your own code generation utilities and add them to Flash Builder as a plug-in. For more information, see Flash Builder Extensibility API Reference .

Any code generation extensions you add as a plug-in to Flash Builder are available from the Code Generator combo box.

Enable Service Manager to use single service instance (singleton) during code generation

By default this option is not enabled. During code generation, each client application in a project creates their own instance of a data service.

If you want a single instance of a service that all client applications in the project share, enable this option.

This option is only available if you specify the default Flash Builder code generation utility.

Debug

The following options for debugging in Flash Builder are automatically enabled. For other options that affect a debugging session see:

• Preferences > General > Web Browser

• Preferences > Run/Debug

Warn when trying to launch multiple debugging sessions

Some platform/browser combinations do not allow concurrent debugging sessions. If you attempt to start a second debugging session, the original debugging session terminates or is disconnected.

USING FLASH BUILDER

Customizing Flash Builder

Leave this option enabled for Flash Builder to warn you when you attempt to start a second debugging session.

Warn about Security Error after launch

In some cases, a web browser issues a security error because it cannot read Flash Player’s security trust file. In most cases, restarting the web browser corrects the security error.

Leave this option enabled if you want Flash Builder to warn you about this type of security error.

For more information, see the TechNote for Flash Player security warning .

Automatically invoke getter functions

When stepping through a debugging session, variables representing accessor (getter) functions are automatically evaluated. Typically, this behavior is useful during a debugging session.

Disable this option if you do not want to automatically evaluate variables representing accessor functions when stepping through a debugging session.

Stand-alone Flash Player version management

When you launch or debug an application from Flash Builder, you can specify the Flash Player executable to use.

To do so, in the Preferences dialog box, select Flash Builder > Debug. Then, define the location of the Flash Player executable that Flash Builder uses to debug or launch your application.

USING FLASH BUILDER

Customizing Flash Builder

When you create a FlexUnit test case class or a FlexUnit test case suite for the selected project, Flash Builder automatically adds the SWC files in the alternative framework directory to the FlexUnit build path.

When you create an alternative FlexUnit framework directory, it is recommended to have the following directory structure for the SWC files:

• flexunit-x.x-as3_x.x.swc

files in the "ASProject" folder. The SWC files in this folder are automatically added to the build path for an ActionScript project.

• flexunit-x.x-flex_x.x.swc

files in the "FlexProject" folder. The SWC files in this folder are automatically added to the build path for a Flex project.

• Any other SWC files that your project requires or that your FlexUnit code has dependencies on (that are not already on the build path) in the "Common" folder. The SWC files in this folder are automatically added to the build path for both ActionScript and Flex projects.

241

If Flash Builder cannot detect the recommended directory structure, the selected alternative directory is added irrespective of whether it is a Flex project or an ActionScript project.

Installed AIR SDK

Flash Builder 4.7 installs the AIR SDK to use for all ActionScript projects. This SDK contains the Adobe AIR SDK, the

ActionScript Compiler, and other required components and files.

Flash Builder installs the Adobe AIR SDK 3.4 by default. Click Check For Updates to check and download an updated version of the AIR SDK if available.

When you import ActionScript projects created in an earlier version of Flash Builder, the projects are automatically upgraded to use the AIR SDK. You can let Flash Builder notify you of this upgrade.

Installed Flex SDKs

Flash Builder uses the Flex SDK for all Flex projects. Flash Builder installs the Flex 4.6 SDK and the Flex 3.6A SDK.

For Flex projects that do not specify an SDK, Flash Builder uses the Flex 4.6 SDK by default.

You can add additional Flex SDKs, remove Flex SDKs, and also change which Flex SDK is the default for Flex projects that do not specify an SDK.

The following types of Flex SDKs are available:

Adobe Flex SDK Released versions of official Adobe products. These SDKs contain a mixture of open and closed source components.

Last updated 12/3/2012

USING FLASH BUILDER

Customizing Flash Builder

To add an Adobe Flex SDK, follow these steps:

1 Download the required Flex SDK to a temporary location on your system from the Flex SDK downloads page.

Check the download page for an explanation of the different build versions, requirements, and license information.

Note: If you want to use a stable, tested release, download a milestone release build. A milestone release build has been declared a major release by the development team. It includes a signed version of the Flex framework RSLs

(required to use RSL caching).

2 Flex SDK downloads are ZIP files. Unpack the ZIP file to a new folder on your system.

It’s a good idea to name the top-level folder with the version number of the SDK.

Typically, you place SDKS in the Flash Builder installation directory at the following location:

<Flash Builder Install Directory>/ sdks/

3 From Flash Builder preferences, select Flash Builder > Installed SDKs.

4 Click Add and browse to the unpacked Flex SDK. Click Apply.

5 For each project that uses the Flex SDK, open this preference dialog and select the SDK to make it the default SDK for that project. Click OK.

When you import Flex projects created in an earlier version of Flash Builder, you are prompted to select the SDK to use. You can disable this prompt for importing projects.

Apache Flex SDK For users who want to download and use the open source Apache Flex SDK.

For more information about downloading and using the Apache Flex SDK, see www.adobe.com/go/apacheflex_flashbuilder .

Network Monitor

The Network Monitor preferences page lists the ports on which the Network Monitor captures events and listens to http requests.

By default, the Network Monitor clears all monitoring entries upon startup. You can disable this preference.

You can also enable the following preferences:

• Suspend monitoring on start

• Ignore SSL Security Checks

Enabling this preference is useful when monitoring network traffic from a self-signed server.

Profiler

By default, both memory and performance profiling are enabled.

• Memory profiling

You typically use memory profiling to examine how much memory each object or type of object is using in the application. Use the memory profiling data when to reduce the size of objects, reduce the number of objects that are created, or allow objects to be garbage collected by removing references to them.

Memory profiling uses much more memory than performance profiling, and can slow your application’s performance.

• Performance profiling

242

Last updated 12/3/2012

USING FLASH BUILDER

Customizing Flash Builder

You typically use performance profiling to find methods in your application that run slowly and that can be improved or optimized.

You can also specify the following preferences for the profiler:

• Connections

Specify the port number that Flash builder listens to when profiling an application. The default port number is

9999. You cannot set it to port 7935, which the Flash debugger uses.

• Exclusion filters

Defines the default packages that are excluded from profiler views.

• Inclusion Filters

Defines the default packages that are included in the profiler views. All other packages are excluded.

• Object References

Specifies the number of back-reference paths to instances of an object to display. The back-reference paths help determine if a path has a back-reference to the garbage collector (GC Root). An instance that is expected to be released, but has references to GC Root, indicates a memory leak.

By default, the profiler displays ten back reference paths. You can specify a different maximum to display or you can specify to show all back-reference paths.

• Player/Browser

You can specify which stand-alone Adobe Flash Player to use and which Web browser to use for profiling external applications. Use a debugger version of Flash Player to successfully profile the application.

When profiling external applications, by default, Flash Builder uses the following Flash Players:

• URL to a SWF file

Flash Builder launches the application’s SWF file using the default browser for the system.

• File system location for a SWF file

Flash Builder opens the application with the default debugger version of the stand-alone Flash Player.
