I am setting an alarm for my reminder app:

PendingIntent sender = PendingIntent.getBroadcast(AddToDoList.this, 
          Integer.parseInt(DBHelperClass.getMaxPrimaryId()), intent, 0);

i am using a unique value (primary ID) to set an alarm. When i want to edit the alarm i am using the same key. But what i see is that both the alarms go off! original as well as edited one.

how do i cancel the old alarm ?
Also these alarms are not working once i switchOff & then again switchOn my device .

    how do i cancel the old alarm ?

    Call cancel() with your original PendingIntent.

    Also these alarms are not working once
    i switchOff & then again switchOn my
    device .

    Alarms do not persist after a reboot. You will need to reschedule the alarms, possibly by a BroadcastReceiver that gets control at boot time.
