Books and Tutorials for OpenGL ES on Android and Object Oriented Programming

Currentlt I'm finding some books to improve my knowl开发者_StackOverflowedge on OpenGL ES and Object Oriented Programming as I would need them sooner or later. Can someone recommend some books or sites that provide good understanding on OpenGL ES and OOP?

For a solid understanding of how OpenGL ES 2.0 works I would suggest OpenGL® ES 2.0 Programming Guide. The book does not try to (nor promises to) turn you into a OpenGL guru, it rather just teaches you the fundamentals. Note that there is a substantial difference between OpenGL ES 2.0 and OpenGL ES (for instance OpenGL ES 2.0 is not backwards compatible).
