AlarmManager in Android works only in an emulator and does not on a physical device

Question

I created an application with AlarmManager and Notification but it works only on an emulator. When I run the app on my physical device the notifications are not shown despite the fact that in app info there is information about the notifications.

EDIT: I've found the solution in this thread

Answer 1

As your Alarm completes 60 secs or whenever you need to trigger the notification, invoke the following function:-

triggerNotification(){
Intent intent = new Intent(getContext(),DailyNotificationReceiver.class);
sendBroadcast(intent);
}
//after every min lapsed invoke this function

This is in java, convert it into kotlin. This sendBroadcast function will internally call your onReceive method
