AIR Flash SQL Scheme Flex

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 as an element of
3、Added as an element of
4、Renamed –>
5、Renamed –>
6、Renamed –> and type is xs:boolean
7、appId was a property within the tag, now is an element tag called
8、version was a property within the tag, now is an element tag

一个成型的Beta 3.0的application.xml的描述如下：
<?xml version="1.0" encoding="utf-8" ?>
