OpenCV4Android : setResolution(Camera.size) is undefined for cameraBridgeViewBase

edit

I am currently working with OpenCV Tutorial 2 - Mixed Process, and I wanted to call a list with resolutions. The code is:

public boolean onOptionsItemSelected(MenuItem item) {
  Log.i(TAG, "called onOptionsItemSelected; selected item: " + item);
  if (item == mItemPreviewRGBA) {
    mViewMode = VIEW_MODE_RGBA;
  } else if (item == mItemPreviewGray) {
    mViewMode = VIEW_MODE_GRAY;
  } else if (item == mItemPreviewCanny) {
    mViewMode = VIEW_MODE_CANNY;
  } else if (item == mItemPreviewFeatures) {
    mViewMode = VIEW_MODE_FEATURES;
  } else if (item == mResolutionMenu) {
    int id = item.getItemId();
    Size resolution = mResolutionList.get(id);
    mOpenCvCameraView.setResolution(resolution);
    resolution = mOpenCvCameraView.getResolution();
    String caption = Integer.valueOf(resolution.width).toString() + "x" +
                     Integer.valueOf(resolution.height).toString();
    Toast.makeText(this, caption, Toast.LENGTH_SHORT).show();
  }
  return true;
}

But Eclipse is giving me the next errors (can't launch the app because of this): The Method setResolution(Camera.size) is undefined for the type CameraBridgeViewBase. These occur for the setResolution() and getResolution().

I have no idea what I'm doing wrong and Google isn't of much help.
