Summary

The latest Android devices are very powerful pieces of hardware and are capable of great graphics, both 2D and 3D. While some optimizations may become less important than just a couple of years ago, new challenges present themselves with the higher and higher resolutions the devices support, the almost ubiquitous support for OpenGL ES 2.0, and the increasingly higher expectations from users. This chapter only scratched the surface of OpenGL ES and only introduced some techniques that are easy to implement and yet can give tremendous results. Luckily for you, there exist many resources to learn about OpenGL, whether you are looking for beginner or advanced material. Also remember to refer to the documentation offered by the GPU vendors (ARM, Imagination Technologies, Nvidia, Qualcomm) as they explain ways to optimize rendering for their own GPU.
