How to Setup Multiple Alarms in Android

Android Set Multiple Alarms

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);
}

How to set multiple alarms using alarm manager in android

You need to use different Broadcast id's for the pending intents. Something like
this:

Intent intent = new Intent(load.this, AlarmReceiver.class);
final int id = (int) System.currentTimeMillis();
PendingIntent appIntent = PendingIntent.getBroadcast(this, id, intent, PendingIntent.FLAG_ONE_SHOT);

Using the system time should be a unique identifier for every pending
intent you fire.

How can I setup multiple alarms in Android?

Ok, when you set an PendingIntent, you're supposed to assign it a unique ID to it, incase you want to identify it later (for modifying/canceling it)

static PendingIntent    getActivity(Context context, int requestCode, Intent intent, int flags) 
//Retrieve a PendingIntent that will start a new activity, like calling Context.startActivity(Intent).
static PendingIntent    getBroadcast(Context context, int requestCode, Intent intent, int flags) 
//Retrieve a PendingIntent that will perform a broadcast, like calling Context.sendBroadcast().

The Request code is that ID.

In your code, you keep resetting the SAME PendingIntent, instead use a different RequestCode each time.

PendingIntent pIntent = PendingIntent.getActivity(context,uniqueRQCODE, newIntent, 0);

It has to be an integer, i suppose you have a primaryid (itemId) that can identify Alarm A from Alarm B.
