Implements CvViewFrameListener2 not found

edit

you also have to add the opencv library to your project.

Properties / Android / library

add the OpenCV library 2.4.5 there

CvViewFrameListener2 is defined inside org.opencv.android.CameraBridgeViewBase

Thank you for your answer, berak. Solved it. Seems like the interface name is misspelled in the tutorial. Instead of CvViewFrameListener2 (which really doesn't exist) I used CvCameraViewListener2 and everything works like a charm.

The same problem here. I tried to folllow this tutorial, but I got stuck at

11 Defines that your activity implements CvViewFrameListener2 interface (...)

It seems like the interface CvViewFrameListener2 doesn't exist in OpenCV library. Has anybody any idea?

Do you have the "OpenCV Library - 2.x.x" Project "imported" and "open" in eclipse ?

If you don't I think you get errors like that on every reference to an opencv class.
