fire alarm manager in every 5 min android

Question

i want to make a service which fire alarm manager in every 5 min interval when my application is running only..so how to do it?

 Intent intent = new Intent(this, OnetimeAlarmReceiver.class);
  PendingIntent pendingIntent = PendingIntent.getBroadcast(context, REQUEST_CODE, intent, 0);

  AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
  alarmManager.set(AlarmManager.RTC_WAKEUP, System.currentTimeMillis() + (5 * 1000), sender);
   Toast.makeText(this, "Alarm set", Toast.LENGTH_LONG).show();

Why do you need a service? You do NOT need a service just to have an alarm going off every 5 minutes. — Mike dg, Oct 07 '11 at 14:37

try this:

alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), 5*60*1000, pendingIntent);

that alarm will be repeating forever until you cancel it, so you need to cancel it on getting the event when you no longer need it.

private class ProgressTimerTask extends TimerTask {
        @Override
        public void run() {
            runOnUiThread(new Runnable() {
                @Override
                public void run() {
                    // set your time here
                    int currenSeconds = 0
                    fireAlarm(currenSeconds);
                }
            });
        }
    }

Inizialize :

     Timer progressTimer = new Timer();
     ProgressTimerTask   timeTask = new ProgressTimerTask();
     progressTimer.scheduleAtFixedRate(timeTask, 0, 1000);

Cancel the AlarmManager in onPause() of the activity.

A much better solution would be to use a Handler with postDelayed(Runnable r, 5000) since you said only when your application is running. Handlers are much more efficient than using AlarmManager for this.

Handler myHandler = new Handler();
Runnable myRunnable = new Runnable(){
   @Override
   public void run(){
      // code goes here
      myHandler.postDelayed(this, 5000);
   }
}

@Override
public void onCreate(Bundle icicle){
   super.onCreate(icicle);
   // code
   myHandler.postDelayed(myRunnable, 5000);
   // to start instantly can call myHandler.post(myRunnable); instead
   // more code
}

@Override
public void onPause(){
   super.onPause();
   // code
   myHandler.removeCallbacks(myRunnable); // cancels it
   // code
}

This wasn't meant to be run in a Service. He was asking how to call something every 5 minutes **only when the app is running**. Starting a Service would have been overkill as the other answers were saying. – DeeV Feb 21 '13 at 21:20

Set Alarm repeating every 5 minutes in Kotlin

val intent = Intent(context, OnetimeAlarmReceiver::class.java)
val pendingIntent = PendingIntent.getBroadcast(context, 0, intent, PendingIntent.FLAG_IMMUTABLE)
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis(), (1000 * 60 * 5).toLong(), pendingIntent)

To cancel Alarm

        val intent = Intent(context, OnetimeAlarmReceiver::class.java)
        val sender = PendingIntent.getBroadcast(context, 0, intent, PendingIntent.FLAG_IMMUTABLE)
        val alarmManager = context.getSystemService(Context.ALARM_SERVICE) as AlarmManager
        alarmManager.cancel(sender)

fire alarm manager in every 5 min android
