Thanks for the info. Also, Android can access OpenGL ES -- that was true a year ago when I briefly looked at Android development. At that time I believe that there was a native interface from the Android SDK to OpenGL ES. That might have changed by now into a Java interface -- maybe something like JOGL. Again, haven't looked in a while.
