1.使用proguardgui混淆器对jar包进行混淆，出现EXCEPTION FROM SIMULATION错误：

This is symptomatic of .class transformation tools that ignore local variable information.

解决方法：在配置文件中去掉-keepattributes LocalVariable*Table这个配置项。

2.引用库正常,对库的代码打成jar包混淆后运行报错Unable to execute dex: Multiple dex files define：
Unable to execute dex: Multiple dex files define Lcom/glblong/socshare/R$anim
解决方法：项目引用了不同版本的jar包导致的，如果libs中的jar包版本都是一致的，那么问题可能出现在使用proguradgui时引入的jar包版本不一致导致的。也就是在混淆过程中,引入的jar包要与项目中使用的jar文件一致。
