I installed a simple project aplication. The aplication is suposed to render a sphere and a thin box, with a sun and a ambient light. the aplication is at most just a copy from the example provided in the site. problem is: When i run the app in my 3.2 android xoom it works fine, but when i run it on a 2.3 android devolpment kit, it runs without the light/shadow, so the objects look flat.

The shadowed/lightened result: http://imageshack.us/photo/my-images/840/86652933.png/

The  failed 2.3 result: http://imageshack.us/photo/my-images/269/img20120509163816.jpg/

Is there a way to switch to sftware render (assuming the problem is a hardware limitation).??
