问题:

one of my apps is throwing the following exception on an Samsung S7:

java.lang.RuntimeException:

Here the code at line 202:

notificationManager.notify(NOTIFICATION_ID, mBuilder.build());

I also use an Samsung S7 and I have never gotten that error. I can't reproduce the error with the ansdroid studio emulator either. So I don't know how to fix an error I can't reproduce. Any idea?

Possible reason is that you update RemoteViews instance before NotificationManager#notify instead of recreating a new one thus producing memory leak. I described this case in another answer
