Hi!
Android on Likebook Mars has that problem that the wallpaper support
is removed from the system. And all the launchers I have tried failed with showing the wallpaper.
So, I took an open source launcher (
LukeLauncher, thanks Luke for it), put a wallpaper image inside it and changed code to show it in background as an ordinary image. And here it is. The trick works. The launcher that can show wallpaper on Likebook Mars (should work also on other devices). More info:

Download APK from:

As this is a quick change, there is no option to change the wallpaper. But I think this is possible with tools like
APK Editor Studio or
APK Tool to replace the wallpaper inside the APK file and resign it. It's location is:
assets/www/icons/wallpaper.png.
Have fun!!
