错误日志类似国外这位朋友，也是在混淆 proguard后遇到这个问题，这个问题困扰很久了，因为之前也排查了很多混淆要注意的东西，但是一直没有查到原因，这次终于有解决办法了。

You may need to add

-keepattributes EnclosingMethod

有用的回答就这么一句，让我好激动，我一试，果然可以了。。。。撒花~~~这句话应该是把内部类保护起来~~~

最后根据这个线索就查到了应该添加-keepattributes Exceptions,InnerClasses,Signature,Deprecated,
                SourceFile,LineNumberTable,*Annotation*,EnclosingMethod 这些全部的功能！这样混淆就应该没问题了。
