    timerCount = new MyCount(3 * 1000, 1000);
    timerCount.start();
  }

        super(millisInFuture, countDownInterval);
      }

      @Override
      public void onFinish() {

      }

      @Override
      public void onTick(long millisUntilFinished) {
        //some script here 
      }   
    } 
}
