The exception means that "o" is an instance of com.mygame.Race, and cannot be cast to an instance of MyInterface. This would happen if "o" sees a different instance of MyInterface, e.g. if there were "MyInterface" declarations in both class loaders. You may want to do a quick check with "dexdump" to ensure that it only appears in one place, and possibly do some reflection calls to ensure that the interfaces "o" implements are what you expect at run time. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Android Developers" group.
