android项目调试证书过期
使用Eclipse编译工程文件时出现：
[2014-12-17 20:10:14 - androidVNC]Error generating final archive: Debug certificate expired on 12/17/14 20:10 PM!
com.android.sdklib.build.ApkCreationException: Debug Certificate expired on 12/17/14 20:10 PM!
解决办法：
删除调试证书
[Linux and Mac OS X] ~/.android/debug.keystore
[Windows] %USERPROFILE%/.android/debug.keystore
然后clean工程，重新编译即可
