You just need to save whatever you are using to make them unique ( requestCode, or Intent ACTION, or whatever) and then use the same parameters to recreate the PendingIntent when you want to cancel the alarms. If you have multiple alarms, the Intents must be unique. You do NOT need to add any extras to the Intent if you just want to use it to cancel an existing alarm. I've used an Activity in the example code, but you can also use a Service or BroadcastReceiver, whatever you are using in your code. Apps that target Android 12 (SDK31) must now specify a mutability flag for any pending intents. PendingIntent.cancel() // delete the PendingIntent PendingIntent pendingIntent = PendingIntent.getActivity(this, requestCode, intent, PendingIntent.NO_CREATE) ĪlarmManager.cancel(pendingIntent) // cancel alarm To recreate the PendingIntent you just do this: Intent intent = new Intent(context, MyActivity.class) What you need to do is to save enough information in the persistent store so that you can recreate the PendingIntent. However, you don't need to save the PendingIntent in a persistent store. Yes, you'll need to provide a PendingIntent to AlarmManager.cancel().

This isn't the right approach to solve this problem. Think we can cancel only through its PendingIntent. Then make the StopServiceReceiver like this, where ServiceYouWantStopped.If you have multiple alarms and you want to cancel a few of them, then I PendingIntent hide = PendingIntent.getBroadcast(this, (int) System.currentTimeMillis(), intentHide, PendingIntent.FLAG_CANCEL_CURRENT)

Let me know if you need help setting something like that up in more detail.Ĭhange your Intent and PendingIntent for the hide action to this: Intent intentHide = new Intent(this, StopServiceReceiver.class) I would recommend that you make the stop action instead fire a custom BroadcastReceiver class which runs the stopService() method inside of its onReceive(). That flag alone will not stop the service.
