Android "Screen Overlay Detected" message if user is trying to grant a permission when a notification is showing

Question

I have Android Marshmallow on a Nexus 6. I am trying to fix the following problem:

If a user is trying to grant permission while a notification is showing, a "Screen overlay detected" message gets displayed and the Request Permission dialog disappears - of course the app does not get the requested permission. (Check screenshot)

I tried to fix the problem by adding "DRAW OVER OTHER APPS" permission - android.permission.SYSTEM_ALERT_WINDOW to the manifest but with no luck.

PS: I am sure the problem is caused by the notification. I do not have any app installed that overlays over other apps, I even turned off all apps with "Draw over other apps" permission in the settings. Did not help..

Anyone knows a solution to that problem?

Answer 1

In the circumstance that I ran across, I was causing the problem myself. It was the result of using a Toast to display information to the user at the same time that I was asking for permission. Both of these actions together cause this type of error.

The other answers might resolve someone else's issue. But I wanted to note that you should be cautious of causing your own overlays errors. Be careful of overlaying something in the view while simultaneously asking for permission.

Answer 2

Uninstall Clean Master app. I uninstalled it and problem solved
