Renderscript error

I'm extracting Android Grass live wallpaper code from the Android source.

I have put it in an Android project.

When I run it and go to wallpaper chooser in order to pick it, I get this error that probably is related to OpenGL and RenderScript, but I can't realize what is the problem exactly.

Thanks for your help.

Update to newest Android SDK(r18) and system images(4.0.3 r2), and it supports OpenGL ES 2.

Start emulator from command line with option "-gpu on".

I have run Balls Renderscripts example successfullly.
