Is the launcher is responsible for drawing the wallpaper on Android?
Pergunta
I'm just wondering if it's the Launchers' responsibility to render the wallpaper/live wallpapers? or if's always drawn below it? so that if i make a transparent launcher i can assume that the wallpaper is there?
Solução
It is a function of the OS and not the launcher: http://developer.android.com/reference/android/service/wallpaper/WallpaperService.html
Outras dicas
If you want to use the system wallpaper as your activity background, set your activity theme to Theme.Wallpaper.
