1.使用proguardgui混淆器对jar包进行混淆，出现EXCEPTIONFROMSIMULATION错误：

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：

Unabletoexecutedex:MultipledexfilesdefineLcom/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。

3.在你依赖的外部jar包已经混淆的情况下再进行混淆打包有可能出现以下情况：

Can't read [***\***.jar] (Can't process class [**/a/f.class] (Unknown verification type [108] in stack map frame))

解决方法:找到proguard源码中proguard\src\proguard\classfile\ClassConstants.java类，然后修改ATTR_StackMapTable的值，将原来的的StackMapTable改为dummy.

publicstaticfinalStringATTR_StackMapTable="dummy";//"StackMapTable";

然后重新ant打包proguard，使用新的proguard来混淆就不会出现上面的问题。
