Timer count in android

Hello friends,

new CountDownTimer(3000, 200) {

    @Override
    public void onTick(long millisUntilFinished) {
    }

    @SuppressLint("NewApi")
    @Override
    public void onFinish() {
       frame_outer.setTest("Number:"+i);
        i++;
        if (i == colors.length - 1) i = 0;
        start();
    }
}.start();

Thank you
