新建系统环境变量，
名字：ANDROID_SDK_HOME
变量值：X:\
X为android文件夹所在
（新的文件夹放在X的根目录下，还要删了原来的，不然还会报错！）
--------------------编程问答-------------------- 我的问题是无法生成APK文件，Console中出现如下提示：
[2011-12-08 15:50:09 - TestTmp] Starting full package build.
[2011-12-08 15:50:09 - TestTmp] Skipping over Post Compiler.
查看bin目录，没有APK文件，有*.class, res\目录下也为空，请高手解答一下。
补充：移动开发 , Android
