The Android 2.1 SDK was released today and the only major update was Live Wallpapers, so I thought I'd better find out what they are all about. What I found was quite surprising, I'd imagined that they would be some sort of animation or video playing on the desktop, a bit like MS DreamScene, but actually they are more akin to a an Android application open as the desktop. Live Wallpapers extend the WallpaperService class and the animations and interactions are handled in code, just like in a game. Realising this it seemed reasonable to try and port the only game I've written for Android, Duck Hunt, into a Live Wallpaper.
After less than an hour the first version of 'Duck Paper' was ready - as the ducks fly past in the background you can touch them to shoot them, then they fall off the screen.
Fortunately there is an example Live Wallpaper in the 2.1 SDK called CubeLiveWallpaper. This is definitely the starting point for anyone looking to create their own Live Wallpaper. I opened up this sample project, played with CubeLiveWallpaper1 and merged its Engine with Duck Hunt's SurfaceView code, et voila we have a Live Wallpaper.
Unfortunately I don't have an Android 2.1 device to try it on and it runs pretty slowly in the emulator. Once I've had it tested on a real device I'll put it in the Android Market.
Update: I've had it tested by a friend with a Nexus One and all seems well, so it is now live in the Android Market

Sorry for my bad english. Thank you so much for your good post. Your post helped me in my college assignment, If you can provide me more details please email me.
Awesome posting. Delighted that you distributed that.
Whenever anybody is attempting to down load wallpapers for mobile phone, these people find it challenging, as mostly individuals in India have substandard quality mobiles.
I am not necessarily usual of commenting however I noticed one excellent resource of transfering just about all your mobile wallpapers, mobile games and mobile animation direct to your cell phone.
I think you have a great page here… today was my first time coming here.. I just happened to find it doing a google search. anyway, good post.. I’ll be bookmarking this page for sure.
Sir, you've said that you played with the Surface View of Duck Hunt right? so does that mean you "imported" an application and "converted" it into Live Wallpaper?
If so, I would like to learn how to do it! You see, I manage to obtain an interactive Android App and I wanted it as a live wallpaper.
Please Help me, Thanks!!
The source for my game is here http://code.google.com/p/android-duckgame/ and my live wallpaper is here http://code.google.com/p/android-duckhunt-livewallpaper/ feel free to browse.
Very nice, I've been using your source code as a base and I have successfully added Accelerometer as well as onShake events.
I'm just wondering if you could help me (or everyone) to develop a simple "space shooter" live wallpaper.
And is there any way I could contact you!? please, I'm interested in this new live wallpaper concept. XD
Sir, can you make a Live Wallpaper object that shoots beams?
Hey. Live Wallpapers have been around for quite a while now, there should be plenty of examples on line. Good luck with the space shooter.
