Android Proguard - how to keep onClick handlers only referenced from XML layouts

Question

In my Android app I ofter don\'t create a View\'s on-click handler in code, but rely on the ability to specify it in the XML layout file, like this:

Answer 1

This seems to be the best answer, as it is 100% robust to naming of such methods:

# This will avoid all the onClick listeners referenced from XML Layouts from being removed
-keepclassmembers class * extends android.app.Activity { 
       public void *(android.view.View); 
}

Hope it helps.
