PlaceMark

Hi, I'm Testing QGlobe and WorldWind for android, and in this moment I want to use a placemark with QGlobe, however I can not do it. Im doing this:

WorldWindGLSurfaceView view = new WorldWindGLSurfaceView(this);
RenderableLayer layer = new RenderableLayer();
PointPlacemark pointPlaceMark = new PointPlacemark(Position.fromDegrees(29, -104, 2e4));
pointPlaceMark.setLabelText("Placemark A");
pointPlaceMark.setLineEnabled(false);
PointPlacemarkAttributes attrs = new PointPlacemarkAttributes();
attrs.setImageAddress("images/test.png");
attrs.setImageColor(new Color(1f, 1f, 1f, 0.6f));
attrs.setScale(0.6);
pointPlaceMark.setAttributes(attrs);
layer.addRenderable(pointPlaceMark);
layer.setPickEnabled(false);
WorldWindow window = WorldWindGLSurfaceView.getWorldWindow();
window.getModel().getLayers().add(layer) ;





Someone of you have the same problerm?
