Class NativeCameraView

java.lang.Object
  SurfaceView
      org.opencv.android.CameraBridgeViewBase
          org.opencv.android.NativeCameraView

public class NativeCameraView
extends CameraBridgeViewBase
extends CameraBridgeViewBase

This class is an implementation of a bridge between SurfaceView and native OpenCV camera. Due to the big amount of work done, by the base class this child is only responsible for creating camera, destroying camera and delivering frames while camera is enabled
