How To Cancel Pendingintent At Specific Time?

AlarmManager works perfectly when I have not declared cancel but do not fire when I declare the cancel.. Here is the code: Calendar c= Calendar.getInstance(); c.set

Solution 1:

Change the line am1.cancel(pi); to am1.cancel(pi1); - you're cancelling the original PendingIntent

Also, in your cancel code, you're calling c.add() (which add on to the current date/time) instead of c.set() (which explicitly sets the next date/time). By calling c.add(Calendar.MINUTE, 38), you're actually adding 38 minutes to the current Calendar, instead of setting the time to 12:38;
