Question

I am trying to make an alarm that would ring at specified n number of times. My code is given below. I am able to get the entries correctly but no alarm rings at all.

public void setAlert(View view) {

    int h[] = new int[TOTAL_ALARMS];
    int m[] = new int[TOTAL_ALARMS];
    Intent intent[] = new Intent[TOTAL_ALARMS];
    PendingIntent pendingIntent[] = new PendingIntent[TOTAL_ALARMS];
    int piID = 12345; 
    Calendar[] cal = new Calendar[TOTAL_ALARMS];
    for (int i = 0; i < TOTAL_ALARMS; i++) {
        cal[i] = Calendar.getInstance();
    }

    for (int i = 0; i < TOTAL_ALARMS; i++) {
        try {

            m[i] = Integer.parseInt(editHour[i].getText().toString());

            h[i] = Integer.parseInt(editMinute[i].getText().toString());

            cal[i].set(Calendar.HOUR, h[i]);
            cal[i].set(Calendar.MINUTE, m[i]);


            intent[i] = new Intent(this, AlarmService.class);
             pendingIntent[i] = PendingIntent.getActivity(this,
                    piID++, intent[i], PendingIntent.FLAG_CANCEL_CURRENT);
            AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
            alarmManager.set(AlarmManager.RTC_WAKEUP,
                    cal[i].getTimeInMillis(), pendingIntent[i]);
            Toast.makeText(this, "Alarm set", Toast.LENGTH_LONG).show();

        } catch (Exception ex) {
            ex.printStackTrace();
            System.out.print("OOPS!");

        }
    }
}

I just answered same question, You are missing defining Receiver in Manifest withe specific intent.

And you must change Second parameter from “123” to random and unique number you can do it by have a int count, and use count ++ in pending intent in place of 123 // fixed
