Leroy,
the OpenGL chapter is about 70 pages long. I would like to think that it is a great OpenGL resource that can get you up and running with OpenGL with out knowing anything about OpenGL ES 1.x.
However android is now moving on to OpenGL ES 2.x which is an entirely different animal.
However one needs to understand all of the concepts that we covered in the book.
There are samples in the book that is really good for an experienced
java programmer but a beginer opengl programmer. This should be a good place to start integrating with the rest of your controls.
However that application integration is not covered in the book. You will be venturing into that space on your own.
