Intel has posted an in-depth article on how to get started with OpenGL ES development for the Android platform. The article details how to work around many of the special challenges of using OpenGL ES on Android not covered in existing literature, including the lack of support for compressed and alpha textures and the trade-offs associated with using OpenGL ES with the Android SDK verses the NDK. It also covers which are the best sample apps to use for new development and how to optimize the Android tools for OpenGL ES development and maximum emulation performance. This is a great place to start regardless of what processor or GPU you are using.
