Use this method as the primary execution point forĭrawing (and re-drawing) graphic objects.

onDrawFrame(): The system calls this method on each redraw of the GLSurfaceView.

Use this method to performĪctions that need to happen only once, such as setting OpenGL environment parameters or Method once, when creating the GLSurfaceView.

onSurfaceCreated(): The system calls this.

The GLSurfaceView.Renderer interface requires that you implement the Separate class and attach it to your GLSurfaceView instance using You must provide an implementation of this interface as a GLSurfaceView.Renderer This interface defines the methods required for drawing graphics in a GLSurfaceView. Implement the touch listeners, as shown in OpenGL training lesson, Touch screen events, you should extend the GLSurfaceView class to This class by creating an instance of GLSurfaceView and adding your OpenGL API calls and is similar in function to a SurfaceView. GLSurfaceView This class is a View where you can draw and manipulate objects using

Understanding how to implement these classes in an activity should be your first objective.

If your goal is to use OpenGL in your Android application, Graphics with the OpenGL ES API: GLSurfaceView and

There are two foundational classes in the Android framework that let you create and manipulate This topic focuses on the Android framework interfaces. If you are familiar with J2ME JSR239 specification, be alert forĪndroid supports OpenGL both through its framework API and the Native Development The specific API provided by the Android framework is similar to the J2ME JSR239 OpenGL ES API,īut is not identical. To see what version of OpenGL the device supports. Want to use 3.0 features if they're available, you should check at run time If you specify that a lower-level version is required but you OpenGL ES 3.0 is required, you can be sure that that version will be present Implementation of this graphics pipeline. The OpenGL ES 3.0 API unless the device manufacturer provides an Regardless of the Android platform version, a device cannot support

OpenGL ES 3.1 - This API specification is supported by Android 5.0 (API level 21) and higher.

OpenGL ES 3.0 - This API specification is supported by Android 4.3 (API level 18) and higher.

OpenGL ES 2.0 - This API specification is supported by Android 2.2 (API level 8) and higher.

OpenGL ES 1.0 and 1.1 - This API specification is supported by Android 1.0 and higher.

Android supports several versions of the OpenGL ES Specification intended for embedded devices.

Standard software interface for 3D graphics processing hardware. OpenGL is a cross-platform graphics API that (OpenGL®), specifically, the OpenGL ES API. Android includes support for high performance 2D and 3D graphics with the Open Graphics Library
