Hi 

I'm a android developer and I want to use Vuforia library, but I can't init camera device to detect and show 3D object. I use this code but this don't work :

Render myRenderer;

    public RajawaliSurfaceView rajawaliSurface;

    @Override

    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.layout_main);

        rajawaliSurface = (RajawaliSurfaceView) findViewById(R.id.rajawali_surface);

        rajawaliSurface.setFrameRate(60);

        rajawaliSurface.setRenderMode(IRajawaliSurface.RENDERMODE_WHEN_DIRTY);

        rajawaliSurface.setTransparent(true);

        rajawaliSurface.setBackgroundColor(Color.WHITE);

        myRenderer = new Render(this);

        rajawaliSurface.setSurfaceRenderer(myRenderer);

    }

please Help me.

Thanks
