WallRoach is an Android App which uses Firebase as its backend to serve high quality Wallpapers to its users.
This was my personal project which I have decided to make Open Source. The code still uses my firebase configuration files which you will have to replace with your own, like # 'google-services.json' in the app folder has to be replaced with your firebase project's google-services.json.
Same goes for the firebase storage bucket URLs. The Code assumes that the all the Wallpapers strored in the Firebase Storage and Firebase Realtime Database are in a particular format.
