Hi, Posted on this a while back but I've been doing some more work on it since. The aim of the augmented reality app I'm developing is to overlay geographical data (roads, hiking trails) on a camera feed for navigation. Following other examples on the web, I've decided to use the raw camera feed as an OpenGL texture and overlay geographic data on top of the texture within a GLSurfaceView. The feed will be black and white for the moment.
Only problem is, it seems to be impossible to capture camera data without creating a SurfaceView to show the preview. However, since you're not supposed to layer SurfaceViews on top of each other, this appears to mean that I presumably have to create an invisible SurfaceView just to be able to capture camera data. The other solutions to this I've seen on the web (nhenze.net and AndAR) seem to layer SurfaceViews on top of each other. Is it therefore true that (prior to Android 3.0) there is simply no elegant solution to the problem? The only solutions people have come up with are either: a) overlay two surfaceviews on top of each other (not guaranteed to work); b) create a "dummy" SurfaceView for the preview just to get PreviewCallback working; or c) reimplement GLSurfaceView from scratch to incorporate a camera feed?
