    mCountdown.start();//start count down
}

...


@Override
public void onTic(QuartzCountdown quartzCountdown, long remainMs) {
    //invoke every intervalMs
    int remainSecond = Math.round(remainMs / 1000f)
}

@Override
public void onStopped(QuartzCountdown quartzCountdown) {
    //invoke after durationMs or stop()
}
