Answer 1

Try calling the following code

    stop.setOnClickListener(new View.OnClickListener() {
        public void onClick(View arg0) {        
            handler.removeCallbacks(runnable);
        }
    });

Where runnable is the runnable which you added while calling postDelayed. Any pending posts of runnable will be removed that are in the message queue.

Try this:

stop.setOnClickListener(new View.OnClickListener() {
        public void onClick(View arg0) {        
             myHandlerThread.interrupt();
             myHandlerThread = null;
        }
    });
