Create handler in activity, then schedule a task. I think Handler is enough for this small task. Don't go for timer.

Runnable timeCounter = new Runnable() {

        @Override
        public void run() {
                 if((currentIndex+1)>imageId.length() ){
                      currentIndex=0;
                  }else{
                      currentIndex++;
                 }
                ViewPager.setCurrentItem(currentIndex);
                handler.postDelayed(timeCounter, 3*1000);

        }
    };
handler.postDelayed(timeCounter, 3*1000);

then in onDestroy() or where ever you want to stop

handler.removeCallbacks(timeCounter);
