Question

What I want is to obfuscate my java file but want to keep the class name and method name as it is. Is there any java obfuscator which provides such functionality?

I have tried pro guard gui obfuscator but can’t get what I want.

Answer 1

ProGuard can do what you describe. If you don’t want it to rename classes and methods:

-keep,allowshrinking,allowoptimization class * { <methods>; }

If you don’t want it to rename, remove, or optimize any entry points at all (e.g. merge classes, inline short methods, inline constant fields, remove unused parameters, etc.):

-keep class * { *; }

At that point, there won’t be much room left to optimize or obfuscate the method bodies, so you may want to evaluate if this is really what you want.
