+/**
+ * An implementation of SurfaceView that uses the dedicated surface for
+ * displaying OpenGL rendering.
+ *
+ * A GLSurfaceView provides the following features:
+ *
+ *
+ * - Manages a surface, which is a special piece of memory that can be
+ * composited into the Android view system.
+ *
- Manages an EGL display, which enables OpenGL to render into a surface.
+ *
- Accepts a user-provided Renderer object that does the actual rendering.
+ *
- Renders on a dedicated thread to decouple rendering performance from the
+ * UI thread.
+ *
- Supports both on-demand and continuous rendering.
+ *
- Optionally wraps, traces, and/or error-checks the renderer's OpenGL calls.
+ *
+ *
+ *
+ *
Developer Guides
+ *
For more information about how to use OpenGL, read the
+ * OpenGL developer guide.
+ *
Using GLSurfaceView
+ *
+ * Typically you use GLSurfaceView by subclassing it and overriding one or more of the
+ * View system input event methods. If your application does not need to override event
+ * methods then GLSurfaceView can be used as-is. For the most part
+ * GLSurfaceView behavior is customized by calling "set" methods rather than by subclassing.
+ * For example, unlike a regular View, drawing is delegated to a separate Renderer object which
+ * is registered with the GLSurfaceView
+ * using the {@link #setRenderer(Renderer)} call.
+ *
+ *
Initializing GLSurfaceView
+ * All you have to do to initialize a GLSurfaceView is call {@link #setRenderer(Renderer)}.
+ * However, if desired, you can modify the default behavior of GLSurfaceView by calling one or
+ * more of these methods before calling setRenderer:
+ *
+ * - {@link #setDebugFlags(int)}
+ *
- {@link #setEGLConfigChooser(EGLConfigChooser)}
+ *
- {@link #setGLWrapper(GLWrapper)}
+ *
+ *
+ *
Specifying the android.view.Surface
+ * By default GLSurfaceView will create a PixelFormat.RGB_888 format surface. If a translucent
+ * surface is required, call getHolder().setFormat(PixelFormat.TRANSLUCENT).
+ * The exact format of a TRANSLUCENT surface is device dependent, but it will be
+ * a 32-bit-per-pixel surface with 8 bits per component.
+ *
+ *
Choosing an EGL Configuration
+ * A given Android device may support multiple EGLConfig rendering configurations.
+ * The available configurations may differ in how many channels of data are present, as
+ * well as how many bits are allocated to each channel. Therefore, the first thing
+ * GLSurfaceView has to do when starting to render is choose what EGLConfig to use.
+ *
+ * By default GLSurfaceView chooses a EGLConfig that has an RGB_888 pixel format,
+ * with at least a 16-bit depth buffer and no stencil.
+ *
+ * If you would prefer a different EGLConfig
+ * you can override the default behavior by calling one of the
+ * setEGLConfigChooser methods.
+ *
+ *
Debug Behavior
+ * You can optionally modify the behavior of GLSurfaceView by calling
+ * one or more of the debugging methods {@link #setDebugFlags(int)},
+ * and {@link #setGLWrapper}. These methods may be called before and/or after setRenderer, but
+ * typically they are called before setRenderer so that they take effect immediately.
+ *
+ *
Setting a Renderer
+ * Finally, you must call {@link #setRenderer} to register a {@link Renderer}.
+ * The renderer is
+ * responsible for doing the actual OpenGL rendering.
+ *
+ *
Rendering Mode
+ * Once the renderer is set, you can control whether the renderer draws
+ * continuously or on-demand by calling
+ * {@link #setRenderMode}. The default is continuous rendering.
+ *
+ *
Activity Life-cycle
+ * A GLSurfaceView must be notified when to pause and resume rendering. GLSurfaceView clients
+ * are required to call {@link #onPause()} when the activity stops and
+ * {@link #onResume()} when the activity starts. These calls allow GLSurfaceView to
+ * pause and resume the rendering thread, and also allow GLSurfaceView to release and recreate
+ * the OpenGL display.
+ *
+ *
Handling events
+ *
+ * To handle an event you will typically subclass GLSurfaceView and override the
+ * appropriate method, just as you would with any other View. However, when handling
+ * the event, you may need to communicate with the Renderer object
+ * that's running in the rendering thread. You can do this using any
+ * standard Java cross-thread communication mechanism. In addition,
+ * one relatively easy way to communicate with your renderer is
+ * to call
+ * {@link #queueEvent(Runnable)}. For example:
+ *
+ * class MyGLSurfaceView extends GLSurfaceView {
+ *
+ * private MyRenderer mMyRenderer;
+ *
+ * public void start() {
+ * mMyRenderer = ...;
+ * setRenderer(mMyRenderer);
+ * }
+ *
+ * public boolean onKeyDown(int keyCode, KeyEvent event) {
+ * if (keyCode == KeyEvent.KEYCODE_DPAD_CENTER) {
+ * queueEvent(new Runnable() {
+ * // This method will be called on the rendering
+ * // thread:
+ * public void run() {
+ * mMyRenderer.handleDpadCenter();
+ * }});
+ * return true;
+ * }
+ * return super.onKeyDown(keyCode, event);
+ * }
+ * }
+ *
+ *

Developer Guides
+ *
For more information about how to use OpenGL, read the

Threading
+ * The renderer will be called on a separate thread, so that rendering
+ * performance is decoupled from the UI thread. Clients typically need to
+ * communicate with the renderer from the UI thread, because that's where
+ * input events are received. Clients can communicate using any of the
+ * standard Java techniques for cross-thread communication, or they can
+ * use the {@link GLStuff#queueEvent(Runnable)} convenience method.
+ *
+ *
EGL Context Lost
+ * There are situations where the EGL rendering context will be lost. This
+ * typically happens when device wakes up after going to sleep. When
+ * the EGL context is lost, all OpenGL resources (such as textures) that are
+ * associated with that context will be automatically deleted. In order to
+ * keep rendering correctly, a renderer must recreate any lost resources
+ * that it still needs. The {@link #onSurfaceCreated(GL10, EGLConfig)} method
+ * is a convenient place to do this.
