Android CountDownTimer

Question

When writing :

 CountDownTimer timer = new CountDownTimer(1000, 100) 
 {
      @Override
       public void onTick(long l) 
       {

       }

       @Overr         


        

Answer 1

CountDownTimer's implementation uses Handler and sendMessageDelayed(), so no background thread is needed. This does mean that the timer will not update if you are tying up the main application thread elsewhere in your code.
