Example of use is available in Solid Launcher
What is Cling library
Cling is a library that allows you to create overlays that will allow the user to be informed of how your application works.
There is already a bunch of libraries to do that, but I wanted a simple and light library that do this quickly, simply and fastly. And also without creating a Bitmap of the size of the screen !
You can display one unique overlay or sequence of overlays. Overlays are represented by Cling
