Setting multiple alarms in android (Alarm Manager)

AlarmManager- This class provides access to the system alarm services. These allow you to schedule your application to be run at some point in the future. When an alarm goes off, the Intent that had been registered for it is broadcast by the system, automatically starting the target application if it is not already running. Registered alarms are retained while the device is asleep (and can optionally wake the device up if they go off during that time), but will be cleared if it is turned off and rebooted. The Alarm Manager holds a CPU wake lock as long as the alarm receiver's onReceive() method is executing. This guarantees that the phone will not sleep until you have finished handling the broadcast. Once onReceive() returns, the Alarm Manager releases this wake lock. This means that the phone will in some cases sleep as soon as your onReceive() method completes. If your alarm receiver called Context.startService(), it is possible that the phone will sleep before the requested service is launched. To prevent this, your BroadcastReceiver and Service will need to implement a separate wake lock policy to ensure that the phone continues running until the service becomes available. 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 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); } And to cancel alarms : alarmmanager.cancel(intentArray.get(i));  //where i is position of alarm you want to cancel. Note: The Alarm Manager is intended for cases where you want to have  your application code run at a specific time, even if your application is  not currently running.  For normal timing operations (ticks, timeouts,  etc) it is easier and much more efficient to use  Handler.
