We first show how to import an existing native GL project into your workspace, and then we show you how to create the same project from scratch. We also cover how to handle various Android events in a native program. From now on, we'll use GL as a shorthand for OpenGL ES 2.0. For 3D graphics, there are other tutorials available, as well as the NativeGlobe example provided in CodeWorks for Android. In this section, we only cover 2D graphics using OpenGL ES 2.0. OpenGL ES provides a fast way to display the camera images, possibly after some image processing, and allows building simple user interfaces.
