Android Setting up GLSurfaceView and OpenGL ES 2.0+


Example

To use OpenGL ES in your application you must add this to the manifest:

<uses-feature android:glEsVersion="0x00020000" android:required="true"/>

Create your extended GLSurfaceView:

import static android.opengl.GLES20.*; // To use all OpenGL ES 2.0 methods and constants statically

public class MyGLSurfaceView extends GLSurfaceView {
    
    public MyGLSurfaceView(Context context, AttributeSet attrs) {
        super(context, attrs);

        setEGLContextClientVersion(2); // OpenGL ES version 2.0
        setRenderer(new MyRenderer());
        setRenderMode(GLSurfaceView.RENDERMODE_CONTINUOUSLY);
    }

    public final class MyRenderer implements GLSurfaceView.Renderer{
        public final void onSurfaceCreated(GL10 unused, EGLConfig config) {
            // Your OpenGL ES init methods
            glClearColor(1f, 0f, 0f, 1f);
        }
        public final void onSurfaceChanged(GL10 unused, int width, int height) {
            glViewport(0, 0, width, height);
        }

        public final void onDrawFrame(GL10 unused) {
            // Your OpenGL ES draw methods
            glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
        }
    }
}

Add MyGLSurfaceView to your layout:

<com.example.app.MyGLSurfaceView
    android:id="@+id/gles_renderer"
    android:layout_width="match_parent"
    android:layout_height="match_parent"/>

To use newer version of OpenGL ES just change the version number in your manifest, in the static import and change setEGLContextClientVersion.
