Android System overlay window

Question

I\'m trying to create a system overlay. But I keep getting \"permission denied\". I\'m using SDK version 23.

My manifest file:

Answer 1

First, there is no permission named SYSTEM_OVERLAY_WINDOW. It is SYSTEM_ALERT_WINDOW.

Second, if your targetSdkVersion is 23 or higher, and you are running on Android 6.0+ devices, your app will not get this permission at the outset. Call Settings.canDrawOverlays() to see if you have the permission, and use ACTION_MANAGE_OVERLAY_PERMISSION to lead the user over to Settings if you do not.
