I want run timer for about 30000 ms and up to 8 or more times each so here is my loop but it runs all timers at once after 30000ms

    public void repeatTimerTask() {

    repeat = 8; // need to run 30 sec timer for 8 times but one after one



    startTimer(30000); // firsat timer for 30 sec



    Handler handler = new Handler();

    for (int a = 1; a<=repeat; a++) {



        final int finalA = a;

        handler.postDelayed(new Runnable() {



            @Override

            public void run() {

                startTimer(30000);



            }



        }, 30000); // delay until to finish first timer for 30 sec

    }

}

To run a timer for n seconds you can use CountDownTimer

 private void startTimer() {



        new CountDownTimer(30000, 1000) {

            int secondsLeft = 0;



            public void onTick(long ms) {

                if (Math.round((float) ms / 1000.0f) != secondsLeft) {

                    secondsLeft = Math.round((float) ms / 1000.0f);

                    // resend_timer is a textview

                    resend_timer.setText("Seconds left( " + secondsLeft + " )");

                }

            }



            public void onFinish() {

                resend_timer.setClickable(true);

                resend_timer.setText("30 sec finished");



            }

        }.start();

    }

Now run this method on loop as per your need.

Please try the below code, and call 'startTimer' method where you first want to start your timer :

private int startTimerCount = 1, repeat = 8;



private void startTimer(){

    // if startTimerCount is less than 8 than the handle will be created

    if(startTimerCount <= repeat){

        // this will create a handler which invokes startTimer method after 30 seconds

        new Handler().postDelayed(new Runnable() {

            @Override

            public void run() {

                startTimer();

            }

        }, 30000);



        // do what you want

        Toast.makeText(this, "startTimer " + startTimerCount, Toast.LENGTH_SHORT).show();

    }

    startTimerCount++;

}
