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
.
