This article introduces how to use OpenGL ES on the Android platform through either the software development kit (SDK) or the Android Native Development Toolkit (NDK) and how to decide which approach to use. The various OpenGL ES sample apps in the SDK and NDK are described as well as the Java* Native Interface (JNI), which allows you to combine Java and C/C++ components. How you decide whether you should target OpenGL ES version 1.1 or 2.0 is also discussed.
