Question: Can someone guide me how to create a live wallpaper in Android. I have referred so many examples but they are too complex to understand. Can any one give simple example like moving horizontal bar or something like that?

Answer: 
You could check `CubeLiveWallpaper` from Android SDK official samples.

You need to install the Samples with Android SDK MAnager.

Then, in Eclipse: 
`File` > `New` > `Other` > `Android Sample Project` > `{Target with Samples}` > `CubeLiveWallpaper`.
