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();

Answer 1

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.

Answer 2

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
}
