Work in progress for drawing to an android canvas and eventually creating a live wallpaper out of it.
Not really useful yet...lots of info at first, take small bytes...! lol... but the class overview is worth a small read if interested... WallaperService
1. Mobile phone with developer options
2. Dev. environment: Android Studio or... Android ADT (all in one compact but useful dev. kit)
3. About 1 hour setup time
The dev kit can create a phone emulator but it will take a little bit to get it working well, real phone's will make your life much easier if you are creating graphics like this.
Android has a live wallpaper feature and it runs using a simple draw and refresh engine to work.
