[AIR]AIR Beta 2.0与AIR Beta3.0的差异和AIR Beta 3.0新增API

自从Adobe将AIR由Beta 2.0升级到Beta 3.0（下称Beta 2.0、Beta 3.0），就发现了越来越多的朋友在Beta2.0下面编写的程序，却无法在Beta 3.0下面运行。我在这里总结一下Beta 3.0新增了哪些API？和Beta 2.0与Beta 3.0 之间的差异！

升级你的Beta 2.0到Beta 3.0的步骤：
首先需要修改的是application.xml这个文件。
1、Change xmlns to “http://ns.adobe.com/air/application/1.0.M6”
2、Added <allowBrowserInvocation> as an element of <application>
3、Added <icon> as an element of <fileType>
4、Renamed <title> –> <name>
5、Renamed <name> –> <filename>
6、Renamed <handleUpdates> –> <customUpdateUI> and type is xs:boolean
7、appId was a property within the <application> tag, now is an element tag called <id>
8、version was a property within the <application> tag, now is an element tag <version> 

一个成型的Beta 3.0的application.xml的描述如下：
<?xml version="1.0" encoding="utf-8" ?>
<application xmlns="http://ns.adobe.com/air/application/1.0.M6">
    <id>SampleApp</id>
    <version>1.2</version>
    <filename>Sample</filename>
    <description>Sample app description</description>
    <copyright>Sample app copyright information</copyright>
    <name>Sample Application </name>
    <initialWindow>
         <title>Main Window</title>
         <content>SampleApplication.swf</content>
         <systemChrome>standard</systemChrome>
         <transparent>false</transparent>
         <visible>true</visible>
         <minimizable>true</minimizable>
         <maximizable>true</maximizable>
         <resizable>true</resizable>
         <width>800</width>
         <height>600</height>
         <x>150</x>
         <y>150</y>
    </initialWindow>
    <fileTypes> 
 <fileType>
   <name>AIR.TextFile</name>
   <extension>aptxt</extension>
   <description>AIR Text File</description>
   <contentType>application/vnd.AIR.text-file</contentType>
   <icon>
       <image16x16>icons/Doc1/txt_16.png</image16x16>    
       <image32x32>icons/Doc1/txt_32.png</image32x32>
       <image48x48>icons/Doc1/txt_48.png</image48x48>
           <image128x128>icons/Doc1/txt_128.png</image128x128>
   </icon>    
 </fileType>
 <fileType>
   <name>AIR.ImageFile</name>
   <extension>apimg</extension>
   <description>AIR Image File</description>
   <contentType>application/vnd.AIR.image-file</contentType>
    <icon>
           <image16x16>icons/Doc2/ft_16_16.png</image16x16>    
        <image32x32>icons/Doc2/ft_32_32.png</image32x32>
        <image48x48>icons/Doc2/ft_48_48.png</image48x48>
          <image128x128>icons/Doc2/ft_128_128.png</image128x128>
    </icon>    
  </fileType>  
</fileTypes>
</application>
