I know there's a lot of information about creating a live wallpaper with renderscript, but I thought I read somewhere that this way of doing things would be deprecated. I don't know if I just imagined that or not, but I don't want to start learning something that won't be supported in the future.
Any good resources or helpful links?
As you can see that it is deprecated from API 16
so that is Android 4.1
http://developer.android.com/reference/android/renderscript/RenderScriptGL.html
so in that case have a look at this.

You can use OpenGL ES 2.0
