打开项目遇到Unknown Android Packaging Problem问题

Unknown Android Packaging Problem AndroidXPLinuxWindowsOS 今天新建项目时突然提示： Description Resource Path Location Type Error generating final archive: Debug Certificate expired on 11-6-11 上午7:58 GraceLol Unknown Android Packaging Problem 而且项目上有个小红叉 原因：Google官方给出了解决办法： 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 也就是删掉.android文件夹下的debug.keystore文件，然后重新build一下获取新的debug.keystore。这样新建项目时就正常了。
