I am trying to prevent proguard from obfuscating interface (or abstract class) methods parameters.

Lets say I have this interface in my lib :

package com.mypackage;
public interface MyLibListener {
    void onSomething(boolean success, String message); 
And this proguard file :
-keepparameternames
-keep interface com.mypackage.MyLibListener {
Then I assemble release and I get :
package com.mypackage;
public interface MyLibListener {
    void onSomething(boolean var1, String var2);
Same thing with abstract classes or using @Keep annotations. Obfuscation option keepparameternames seems to work only for regular classes. Any idea? Thanks!

                @sinek I tried so many things (at the time I asked) but never found the solution :( I did not try recently sorry. Tell us if you find the way

To keep all public and protected methods, which could be used by reflection:
-keepclassmembernames class * {
    public protected <methods>;
While I don't understand, why one would want to keep abstract classes, which cannot be instanced anyway, therefore it's pointless to keep & know their names. In theory, one could exclude all that is not abstract with rules which start with -keep !abstract, but that's kind of redundant.
Your proguard file may lack some -keepattributes, especially a -keepattributes Signature.
Check this example proguard configuration for a library from the proguard documentation to look for ideas.
