  • Animation/Notification visible from outside of app

    Is it possible to make elements outside of the app visible from other apps? For example the screen gets dark for half a second every n seconds.It just has to be kind of a notification that goes all over the screen. If this is possible how can i do it?

    My Smartphone contains a function which makes the edges of the screen light in a color when i received a whatsapp message. Maybe i can use this? Ill appreciate your answers!
