[2014-04-28 11:56:03 - 新闻] but not all the versions are identical (check is based on SHA-1 only at this time).
[2014-04-28 11:56:03 - 新闻] All versions of the libraries must be the same at this time.

[2014-04-28 11:56:03 - 新闻] Jar mismatch! Fix your dependencies分析 ： 有2个v4的jar包
解放方案 ：直接将library中的v4jar覆盖自己项目中的v4jar即可！
并且要注意的是，当我们导入library的时候Android的API版本一定要一致，不然的话引入会出错！
