Android Packaging Problem错误解决方法

Android项目上出现红叉，而代码和路径无误，爆出错误信息如下：（在problem视图中）

Description ResourcePathLocationType

Error generating final archive: Debug Certificate expired on 12-4-25 上午8:35aaUnknownAndroid Packaging Problem

解决办法：

Project->Clean

原因：

To fix this problem, simply delete the debug.keystore file. The default storage location for AVDs is in ~/.android/avd on OS X and Linux, in C:\Documents and Settings\\.android\ on Windows XP, and in C:\Users\\.android\ on Windows Vista.
The next time you build, the build tools will regenerate a new keystore and debug key

另外：

android的key到期，也会出现上述问题，解决方法是：C:\Users\Freshen\.android（不同OS路径应该不同）这个目录下有个文件debug.keystore删掉，然后关闭工程，再打开应该就可以。
