Android Set Multiple Alarms

by

If you want to set multiple alarms (repeating or single), then you just need to create their PendingIntents with different requestCode. If requestCode is the same, then the new alarm will overwrite the old one.

Here is the code to create multiple single alarms and keep them in ArrayList. I keep PendingIntent‘s in the array because that’s what you need to cancel your alarm.

// context variable contains your `Context`
AlarmManager mgrAlarm = (AlarmManager) context.getSystemService(ALARM_SERVICE);
ArrayList<PendingIntent> intentArray = new ArrayList<PendingIntent>();

for(i = 0; i < 10; ++i)
{
   Intent intent = new Intent(context, OnAlarmReceiver.class);
   // Loop counter `i` is used as a `requestCode`
   PendingIntent pendingIntent = PendingIntent.getBroadcast(context, i, intent, 0);
   // Single alarms in 1, 2, ..., 10 minutes (in `i` minutes)
   mgrAlarm.set(AlarmManager.ELAPSED_REALTIME_WAKEUP, 
                SystemClock.elapsedRealtime() + 60000 * i, 
                pendingIntent); 

   intentArray.add(pendingIntent);
}
