Displaying Android views on top of OpenGL ES display layer

Hello, 

I've successfully modified the "ImageTargets" application and am able to render objects using OpenGL (pretty much modified the teapot rendering code). However, I am trying to also display a View type object (FrameLayout on top of a RelativeLayout). The code displays the Views fine on an independent app but when running on the app where OpenGL renders its objects, I cannot see any View objects. 

I'm not sure if Views can be viewd on top of OpenGL layer. So the question is, can you use Android views on top of OpenGL layer? If so, are there any concerns? Any hint would be helpful.

Thank you.
