启动Android工程,看看时间，整整一个月没有在Gentoo下用Eclipse开发Android了。

  Error generating final archive: Debug Certificate expired on 11-3-4 下午10:57	MyDownload		Unknown	Android Packaging     Problem

Delete your debug certificate under ~/.android/debug.keystore (on Linux and Mac OS X); the directory is something like %USERHOME%/.androidon Windows.

The Eclipse plugin should then generate a new certificate when you next try to build a debug package. You may need to clean and then build to generate the certificate.
