Same problem with my app. In the main activity, I had to render OpenCV utilizable. (I am assuming your app threw a link error when Mat library was used). All sample apps do this. Include this your in main activity.

 private BaseLoaderCallback mLoaderCallback = new BaseLoaderCallback(this) {
        @Override
        public void onManagerConnected(int status) {
            switch (status) {
                case LoaderCallbackInterface.SUCCESS:
                {
                    Log.i("OpenCVManager setup", "OpenCV loaded successfully");
                  //Use openCV libraries after this  
                } break;
                default:
                {
                    super.onManagerConnected(status);
                } break;
            }
        }
    };

    @Override
    public void onResume()
    {
        super.onResume();
        OpenCVLoader.initAsync(OpenCVLoader.OPENCV_VERSION_2_4_9, this,
                mLoaderCallback);
    }
