Following the C++ (OpenGL) repository, I recently added an Android OpenGL ES repositry (using Java) over here. It currently only contains two public demos, one for a simple stl viewer and another one for using the camera input of an android device as an OpenGL ES texture, but over time I plan on adding more and more demos.
And though I used to mock Java in the past I really like coding with Java nowadays. It’s partially because of the language itself (with all it’s modern features) but also because Eclipse is an awesome IDE. So expect more android demos and sources from me in the future.
