build a AS Demo success but screen is black

 

// Initialize the renderer
mRenderer = new FastCVSampleRenderer( this );
mGLSurface = mRenderer.getGLSurfaceView();
mGLSurface.setZOrderMediaOverlay(true);
mGLSurface.setVisibility( View.VISIBLE );
mGLSurface.setRenderMode( GLSurfaceView.RENDERMODE_WHEN_DIRTY );
mRootViewGroup.addView(mGLSurface);

// Camera surface is required for Camera to send
// preview frame callback on some devices.
// The order this is added to the rootViewGroup matters to ensure it is
// below GLSurface. GLSurface is actually used for rendering.

// Further note, when splash screen is not used this should be added
// after GLSurfaceView. Really tricky to get ordering correct.

mCamera = Camera.open();
mCamSurface = new CameraSurface( this, mCamera );
mRootViewGroup.addView(mCamSurface);

bringControlsToFront();
startPreview();
System.gc();

in this block, mCameSurface run success, but mGLSurface is black, I tried to adjust their order, but it also failed.
