Anyone have any insight at all? Was I not clear about my problem? I am simply trying to zoom in or zoom out on the camera preview but I am not using the Camera smooth zoom API in 2.2 since it seems to only work for levels of zoom that are different for each phone/camera. Also, it appears that it can not zoom using a floating point scale.
If I try scaling the FrameLayout around the preview SurfaceView it looks like it kind of works, but the preview goes completely black while the animation is running. I am starting to think maybe this will work by grabbing each frame from the preview and drawing to a canvas white scaling, but this seems over-complicated compared to using the Animations API. If someone can help point me in the right direction that would be awesome!
