I'm trying to find a way to customize the APButton, but nothing worked. Can anybody tell me a way how to do it? Or how Processing works together with the Android SDK. 

I thought that Processing uses the android.jar of the SDK and thus I replaced the default buttons in the android.jar but still... The buttons are the same. Trying to find out what default buttons APButton especially use, didn't help either because i could not even find a hint. 

I'm not looking for a general solution. I only need it for an exhibition thus i do not have to take care of other apps.

Thanks for your help.
