Setting ProGuard to obfuscate local variables and arguments

Question

I can\'t seem to find the setting that will obfuscate the local variables, inside methods of a class which is obfuscated.

Here\'s an excerpt from one of the classes

Answer 1

You should remove or refine the option -keepattributes. It implies keeping attributes with local variable names:

-keepattributes LocalVariableTable,LocalVariableTypeTable

You could at least exclude those

-keepattributes !LocalVariableTable,!LocalVariableTypeTable

Ideally, you'd only preserve the attributes that are strictly required.

See the ProGuard manual > Usage > -keepattributes
