You can do lots of interesting tricks with memory with shaders,
particularly pixel shaders. Many implementations put all types of
wild data into textures that aren't images and access that with a
swizzle in the pixel shader as whatever 32 bit values they needed.

fixed-function emulation.

your problem has nothing to do with android. I think you may need a
3D refresher to solve it. Normals are not UVs. Your UVs will depend
on how you want to map, but the easiest way to do it is to map from
the sphere center out using angles, like this. Since GL has 2D
texture coordinate
Also I should add that your sphere normal should be (sphereCenter -

Pedro,
Java (and pretty much any language's) trig functions work with angles
