Some notes on this thread and some code... 1. You need the Surface and it must be as large as the preview image, though it doesn't have to be visible. Don't set SURFACE_TYPE_PUSH_BUFFERS. 2. Don't try to process the preview in the preview callback. There isn't enough time and you will crash the system. The camera won't work until after reboot. 3. In a separate Thread, decode the preview data like this: http://groups.google.com/group/android-developers/msg/d3b29d3ddc8abf9b - Hope this helps, David
