Cancel Alarm

Cancel a currently active or future system alarm.

If there are two or more matching alarms, or on some devices always, Android will show a UI allowing the user to select the desired alarm. Therefore, for best results when automating, it's recommended to give each alarm a unique label and then use that for cancellation.

If the specified alarm is a repeating alarm, then only the next instance is cancelled (the alarm remains enabled)

Some modes are poorly implemented by many Android devices. For instance, snooze time may be ignored.
