For instance, the Grass wallpaper uses the phone's location to compute sunrise and sunset times in order to display the appropriate sky.Ĭreating your own live wallpaper is easy, especially if you have had previous experience with SurfaceView or Canvas.
The live wallpapers included on Nexus One demonstrate the use of some of these APIs to create fun and interesting user experiences. A live wallpaper is very similar to a normal Android application and has access to all the facilities of the platform: SGL (2D drawing), OpenGL (3D drawing), GPS, accelerometers, network access, etc. With the introduction of live wallpapers in Android 2.1, users can now enjoy richer, animated, interactive backgrounds on their home screen.
