I'm new in andengine . I create following code

public class MainActivity extends BaseGameActivity {


static final int CAMERA_WIDTH = 800;
static final int CAMERA_HEIGHT = 480;

public Font mFont;
public Camera mCamera;

//A reference to the current scene
public Scene mCurrentScene;
public static BaseActivity instance;

public EngineOptions onCreateEngineOptions() {
    instance = this;
    mCamera = new Camera(0, 0, CAMERA_WIDTH, CAMERA_HEIGHT);

    return new EngineOptions(true, ScreenOrientation.LANDSCAPE_SENSOR, new RatioResolutionPolicy(CAMERA_WIDTH, CAMERA_HEIGHT), mCamera);
}


@Override
public void onCreateResources(OnCreateResourcesCallback arg0)
        throws Exception {

    mFont = FontFactory.create(this.getFontManager(),this.getTextureManager(), 256, 256,Typeface.create(Typeface.DEFAULT, Typeface.BOLD), 32);
            mFont.load();
}

@Override
public void onCreateScene(OnCreateSceneCallback arg0) throws Exception {

    mEngine.registerUpdateHandler(new FPSLogger());
    mCurrentScene = new Scene();
    Log.v("Scene","enter");
            mCurrentScene.setBackground(new Background(0.09804f, 0.7274f, 0.8f));
 //             return mCurrentScene;

}

@Override
public void onPopulateScene(Scene arg0, OnPopulateSceneCallback arg1)
        throws Exception {
    // TODO Auto-generated method stub

}

 }

I got code on sites there is returning scene but in AndEngine GLES2 in method onCreateScene() there is no return scene ... so my First run is BLACK .. any suggestion :)
