I am currently working on an alarm to be included in a bigger project. Everything is working correctly with the datepicker/timepicker. And the alarm does start once the date and time has been reached. The problem i am having is the only way to stop the alarm is by closing the application. I have added a button (stopAlarm) with everything i thought would be needed to stop this pending intent, but it is still not stopping the alarm?
I am probably overlooking something very small but i was wondering if there is anyone who can point me in the right direction?
Thanks!
