	An Activity created a handler in a method and passed it on to a singleton. Singleton holds this handler so that it can send the message back to activity. Activity handles the message in that local method by implementing the handleMessage(Message mesg) methond. What happens if the activity gets destroyed and singleton tries to send the message via the handler. asked 4 mins ago
