I want to know about OpenGL in Android. I want to learn it. [closed]

It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its curre开发者_如何学运维nt form. For help clarifying this question so that it can be reopened, visit the help center. Closed 11 years ago.

Please, send me some demo application of OpenGL or tutorial of it.
