Hello Everybody,

We are pleased to announce that the AIR 2.5 runtime for Android will be available on the Android Market starting 10/8. On this date we will make an announcement to this prerelease when the AIR runtime is live on the Android Market, after which you can upload your AIR applications for end user download.

Because 10/8 is rapidly approaching, we encourage all of you to test your applications against the latest AIR for Android SDK/runtime on this prerelease site. The 09/16/10 build will be one of our final builds, therefore it’s critical that we identify any issues as soon as possible. If you discover any new problems with the AIR SDK or runtime, please file a bug immediately.

The AIR 2.5 SDK will be released on http://www.adobe.com/products/air/ at a later date, but we will drop the final AIR 2.5 SDK/runtime to this prerelease site for you to repackage and test your application before uploading it to the Android Market. As a reminder, all of you are under an NDA that prevents you from disclosing any of this information publicly.

Please accept our heartfelt thanks in making this prerelease program a successful one (and the largest Adobe prerelease program ever). The excellent feedback you have given us have been tremendously valuable in enabling us to launch the highest quality product possible.

Sincerely,
The AIR Team

在FlashBuilder中引入该swc，这时就能在代码中直接new这个fl组件了

How to Use Flash CS’s Components in Flex Builder

To generate the .swc file in Flash CS3, we follow these steps:

1) Make a new Flash CS3 ActionScript 3.0 .fla file.
2) Drag the desired component(s) to the Library. In this example, we’ll drag the TextArea component to the Library.
3) Choose File > Export > Export Movie.
4) For File name, enter v3components.swf. (We don’t even want the generated .swf, but there’s no other way to get the .swc to compile.)
5) Select a folder in which to save the .swf file.
6) Click Save.
7) In the Export Flash Player dialog, check Export SWC.
Click OK.

The preceding steps generate two files, cs3 components.swf and v3components.swc, both of which are placed in the folder selected in Step 5.

Now let’s use cs3 components.swc in a Flex Builder project. Follow these steps:

1) In Flex Builder, select File > New > ActionScript Project.
2) For Project name, enter “V3Test.as”.
3) Click Next.
4) For Main source folder, enter “src”.
5) For Main application file, enter “V3Test.as”.
6) On the Library path tab, click Add SWC.
7) Browse to the v3components.swc file from the preceding procedure.
Click Finish.
9) Update the code in cs Test.as so it looks like this:

package {
  import flash.display.Sprite;
  import fl.controls.TextArea;
  public class V3Test extends Sprite {
    public function V3Test() {
      var t:TextArea = new TextArea();
      t.text = "You're not cookin'";
      addChild(t);
    }
  }

}
10) Run the project.

Adobe has publicly pushed the Flex 4.1/Flash Builder 4.0.1 update, which includes:

Flex4中动态加载CSS文件的方式已经和Flex3有了一定的区别

主要步骤如下：

1.编写不同的CSS文件

见后文

2.将CSS文件编译成SWF文件

在FlashBuilder中右键CSS文件，选择Compile CSS to SWF，

这时bin-debug目录下的对应位置就会生成一个与CSS同名的SWF文件。

选中后该选项前会有勾，之后只要修改了CSS文件，就会自动编译成SWF

2.用styleManager加载SWF

代码中这样写：

this.styleManager.loadStyleDeclarations2(“MyCss1.swf”);   //代码中填写上一步由CSS生成的SWF文件路径

CSS写法：

MyCss1.css

/* CSS file */

/*命名空间*/

@namespace s “library://ns.adobe.com/flex/spark”;

@namespace mx “library://ns.adobe.com/flex/mx”;

/*使用skin类来定义皮肤，所以要用ClassReference函数*/

s|List{

skin-class:ClassReference(“skins.ListSkin1″);

}

/*符号#代表指定的ID*/

s|Label#labelExamples{

font-size:14;

color:#990099;

}

s|CheckBox{

font-size:9;

color:#FF3300;

}

s|RadioButton{

font-size:92;

color:#990099;

}

s|Button{

font-size:32;

color:#FF3300;

}

注：CSS中无法设置ItemRenderer，所以如果要实现不同CSS用不同的ItemRenderer，为各个CSS指定不同的skin类，并且在skin类中分别设置的ItemRenderer

例如，我的例子中要为List设置不同的ItemRenderer，就不要写成<s:List itemRenderer=”itemRenderers.ListItemRenderer1″…/>

而要在CSS中为List指定skinClass为skins.ListSkin1，代码：skin-class:ClassReference(“skins.ListSkin1″);

然后，在skin.ListSkin1中设置ItemRenderer，代码：

<s:DataGroup id=”dataGroup” itemRenderer=”itemRenderers.ListItemRenderer1″>

<s:layout>…

Base64Encoder用法如下：

var $orgin:String = this.textOrigi.text;//获取原始字符串
var $base64:Base64Encoder = new Base64Encoder();
$base64.insertNewLines = false;//该值等于true时，输出的结果会自动换行，默认为true，
$base64.encodeUTFBytes($orgin);//这里注意，如果想加密中文就不要使用$base64.encode();
var $result:String = $base64.toString();//输出结果

Base64Decoder用法如下：

				var $origi:String = this.textEncodeResult.text;//获取原始字符串
				var $base64:Base64Decoder = new Base64Decoder();
				$base64.decode($origi);
				var $result:String = $base64.toByteArray().toString();//输出结果，decode类只能输出ByteArray类型的数据，因此要转换成string

完成代码：

<?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:Script>

			import mx.utils.Base64Encoder;

				var $orgin:String = this.textOrigi.text;//获取原始字符串
				var $base64:Base64Encoder = new Base64Encoder();
				$base64.insertNewLines = false;//该值等于true时，输出的结果会自动换行，默认为true，
				$base64.encodeUTFBytes($orgin);//这里注意，如果想加密中文就不要使用$base64.encode();
				var $result:String = $base64.toString();//输出结果
				this.textEncodeResult.text = $result
			}

			protected function btnDecode_clickHandler(event:MouseEvent):void
			{
				var $origi:String = this.textEncodeResult.text;//获取原始字符串
				var $base64:Base64Decoder = new Base64Decoder();
				$base64.decode($origi);
				var $result:String = $base64.toByteArray().toString();//输出结果，decode类只能输出ByteArray类型的数据，因此要转换成string
				this.textDecodeResult.text = $result
			}

使用代码片断工具，您可以存储内容（文档中重复出现的代码如public function …( ):void{   }等）以便快速重复使用。多种软件都含有此工具（例如Dreamweaver），flexbuilder中此工具包含在CFEclipse插件中。

1.2 安装与使用

安装步骤：

a．  帮助       安装新软件；

b．  使用（W）一栏中输入地址   http://www.cfeclipse.org/update

c．  输入网址后按Enter，程序连接服务器，窗口显示“暂挂中”，连接完毕后窗口会显示出可供安装的程序，选择CFEclipse CFML Editor   点 下一步

d．  点 完成  开始下载   出现安全警告提示软件未签名 点击确定  之后按提示重启flex builder

e．  打开工具窗口（Snip Tree View）；

f．   编辑代码片断   新建片断

g．  按钮插入该片断（只适用于AS代码文件）

h．  片断中适用参量：$${    }   如图中代码

在插入该片断时会出现提示框，要求输入$${}标记的参数值name  如图

确定后整段代码被插入

而这次遇到的问题是这样的：

发布时只发布一个主程序（Web或者Air方式），而不发布所需要的module及其依赖的swc，只在运行时根据需要加载module及其依赖的swc

1.       建立一个实验用的module工程：

先准备一个module工程，普通的Flex Project（web）即可，主程序名无所谓，因为这个工程只是为了编译module对象用的

在Properties->Flex Build Path中引入所要依赖的swc，这个例子中使用了TweenLite.swc

注意AIR project的默认Link Type是Merge into code，改成RSL。如图：

新建一个包modules并新建一个module程序：MyModule1.mxml

到Properties->Flex Modules中修改该module的optimize属性为none，如下图

点击Edit按钮，弹出下图

选择Do not optimize(…)

在MyModule1.xml中使用TweenLite做一个简单的动画:

TweenLite.to(<strong>this</strong>.goed,4,{x:500});

编译工程，

此时MyModule1.mxml被编译生成为MyModule1.swf

TweenLite.swc会被编译成TweenLite.swf

复制到要被加载的目录下，我的是

http://127.0.0.1/testflex/TweenLite.swf

http://127.0.0.1/testflex/modules/MyModule1.swf

2.       建立主工程（Flex Web）：

新建一个Flex Project(web),不要使用引入TweenLite.swc

新建一个用来控制加载TweenLite的类：

tasks/TaskLoadRSL.as

在这个类中，使用URLLoader将TweenLite.swc从http://127.0.0.1/testflex/TweenLite.swf上加载下来，主要代码如下：

var loader:Loader = new Loader();
var context:LoaderContext = new LoaderContext();
context.applicationDomain = ApplicationDomain.currentDomain;//必须有这一句，RSL必须和主程序在同一个域中
loader.load(new URLRequest(this.web),context);
loader.contentLoaderInfo.addEventListener(Event.COMPLETE,localLoadCompleteHandler);
loader.contentLoaderInfo.addEventListener(IOErrorEvent.IO_ERROR,localLoadIoErrorHandler);

加载完TweenLite后不需要任何操作，直接开始加载module即可

使用IModuleInfo或ModuleLoader加载module都可以，详见源代码

3.       建立主工程 （AIR）：

Air中比Flex要麻烦，因为发布时只发布主程序，所以运行时需要先检测本地是否有swc和

module

如果有就直接加载运行（同Web）

如果没有就从网站上下载到本地，然后再加载

主要代码如下：

从网络地址上加载：

var loader:URLLoader = new URLLoader();
loader.dataFormat = URLLoaderDataFormat.BINARY;
loader.addEventListener(Event.COMPLETE, loadFromWebCompleteHandler);
loader.addEventListener(IOErrorEvent.IO_ERROR, loadFromWebErrorHandler);
loader.load(new URLRequest(web))

var loader:URLLoader = URLLoader($e.target);
var data:ByteArray = ByteArray(loader.data);
var file:File = new File(File.applicationDirectory.resolvePath(this.local).nativePath);
trace('save file to' + file.nativePath);
var fileStream:FileStream = new FileStream();
fileStream.open(file, FileMode.WRITE);
fileStream.writeBytes(data);
fileStream.close();
this.loadFromLocalFile();
