Eclipse开发Android出现Jar mismatch! Fix your dependencies

用Eclipse开发Android项目是，控制台出现

Jar mismatch! Fix your dependencies 

Found 2 versions of android-support-v4.jar in the dependency list,

but not all the versions are identical (check is based on SHA-1 only at this time).

All versions of the libraries must be the same at this time.

这是由于各个项目的android-support-v4.jar不一致。

解决办法：将所有libs中的android-support-v4.jar统一（将各个android-support-v4.jar删除，在添加上相同的android-support-v4.jar），然后刷新包就OK了。
