Callback Interface  Callback interface us used for Fragment to Fragment communication in android.  Handler class can be used to register to a thread and provides a simple channel to send data to this thread. – A Handler object registers itself with the thread in which it is created. For example, if you create a new instance of the Handler class in the onCreate() method of your activity, the resulting Handler object can be used to post data to the main thread. – counterHandler = new Handler(counterCallback); – counterHandler.sendEmptyMessage(0); 3 Fall 2014 CS7020: Game Design and Development
