If you are using SurfaceView, you will need to register a SurfaceHolder.Callback with addCallback(SurfaceHolder.Callback) and wait for surfaceCreated(SurfaceHolder) before calling setPreviewDisplay() or starting preview. The one exception is that if the preview surface texture is not set (or set to null) before startPreview() is called, then this method may be called once with a non-null final void startFaceDetection() Starts the face detection. When a preview frame arrives and there is still at least one available buffer, the buffer will be used and removed from the queue.

To save * setup/teardown time, a client of Camera can pass an initialized Camera * object to a MediaRecorder to use for video recording.
