I don\'t know how I can describe this issue. I searched a lot, but I didn\'t find any solution.
Also this solution did not help me -keepattributes EnclosingMethod:
Adding these lines to proguard-rules.pro file fixed my issue.
-keepattributes EnclosingMethod -keepattributes InnerClasses
I suggest -dontwarn InnerClasses
-dontwarn InnerClasses
