3D with OpenGL

Android includes support for high performance 2D and 3D graphics with the Open Graphics Library (OpenGL) API—specifically, the OpenGL ES API. OpenGL is a cross-platform graphics API that specifies a standard software interface for 3D graphics processing hardware. OpenGL ES is a flavor of the OpenGL specification intended for embedded devices. The OpenGL ES 1.0 and 1.1 API specifications have been supported since Android 1.0. Beginning with Android 2.2 (API Level 8), the framework supports the OpenGL ES 2.0 API specification.

Note: The specific API provided by the Android framework is similar to the J2ME JSR239 OpenGL ES API, but is not identical. If you are familiar with J2ME JSR239 specification, be alert for variations.

The Basics

Android supports OpenGL both through its framework API and the Native Development Kit (NDK). This topic focuses on the Android framework interfaces. For more information about the NDK, see the Android NDK.

There are two foundational classes in the Android framework that let you create and manipulate graphics with the OpenGL ES API: GLSurfaceView and GLSurfaceView.Renderer. If your goal is to use OpenGL in your Android application, understanding how to implement these classes in an activity should be your first objective.
