opencv for android2.4.4 How to instantiate a CameraBridgeViewBase surface with out xml

edit

CameraBridgeViewBase is base abstract class. You need to instantiate NativeCameraView or JavaCameraView object. Both of them uses OpenCV classes and functions and must be constructed after OpenCV initialization. I recommend you to use public JavaCameraView(Context context, AttributeSet attrs) or public NativeCameraView(Context context, AttributeSet attrs) constructor to fully initialize camera.
