Android: Get all PendingIntents set with AlarmManager

To cancel all alarm, first you have to find all the pending intent for that and cancel alarm using that.

// set up alarm 
List<PendingIntent> mPendingIntentList = new ArrayList<PendingIntent>();
Intent alarmIntent = new Intent(getApplicationContext(),Receiver.class);
alarmIntent.setData(Uri.parse("custom://" + alarm.ID));
alarmIntent.setAction(String.valueOf(alarm.ID));
AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);

PendingIntent displayIntent = PendingIntent.getBroadcast(getContext(), 0,                  alarmIntent, 0);

// add pending intent in list
mPendingIntentList.add(displayIntent );
alarmManager.set(AlarmManager.RTC_WAKEUP, alarmDateTime, displayIntent);



    //cancel all alarms
    for(int idx = 0 ; idx < mPendingIntentList.size() ; idx++){
       alarmManager .cancel(mPendingIntentList.get(idx));
    }

See AlarmManager.cancel(PendingIntent)

Create a PendingIntent matching the intent(s) you wish to cancel. Calling the above function once, will cancel all matching alarms .
