How is it possible to add Views/Images to my homescreen?
The best example is the facebook messenger: If you long-click at a chat item, you can choose "pop out cheat head", then you have a small button overlaying your screen.
There are also apps like screen-breakers, an image from a broken display overlays everything from the phone.
I've searched for it, but I have no idea what it is called.
I hope you guys are able to understand my english.
