Question

I want to set image over home screen when my app runs, like crack screen applications(Ex: https://play.google.com/store/apps/details?id=mk.g6.crackyourscreen&hl=en) to achieve something.

I beileve it has something to do with these permissions;
DISPLAY SYSTEM-LEVEL ALERTS
DISPLAY UNAUTHORIZED WINDOWS

But i cant find an example, tutorial or any article about it?

Thanks…

You should be able to do this by setting a transparent activity. For that matter, you can make your activity use the Translucent theme, like this (put this in the Manifest):

<activity android:theme="@android:style/Theme.Translucent.NoTitleBar">
