how to tell proguard not to obfuscate certain method names in my class?

Question

An external collections library that I'm using allows me to execute a where method on a list of custom objects. It needs the method/property name that I want to filter on and it takes it as a string. Because of obfuscation being done, the method doesn't seem to exist.

I'm trying to tell proguard not to obfuscate methods on that object but it's not working.

In proguard config, I'm trying this

-keep public class com.mop.mobile.myproject.obj.MyClass**
-keepnames public class com.mop.mobile.myproject.obj.MyClass**

here's the logcat trace

just as a reference, this also seemed to work as well http://stackoverflow.com/questions/7880107/in-proguard-how-to-preserve-a-set-of-classes-method-names — topwik, Oct 09 '12 at 20:59

Try this:

-keep public class com.mop.mobile.myproject.obj.MyClass { *; }

instead of

-keep public class com.mop.mobile.myproject.obj.MyClass**

To tell proguard not to obfuscate methods/attributes of a certain class use these lines...

keepclassmembers class com.mop.mobile.myproject.obj.MyClass{*;}

keepattributes com.mop.mobile.myproject.obj.MyClass

It worked for me .
