Android expected android.support.v4.app.Fragment for CameraFragment subclass

The fragment manager looks like this:

FragmentManager fragmentManager = getSupportFragmentManager();
    switch (position) {
        case 0:
            fragmentManager.beginTransaction()
                    .replace(R.id.container, ReviewFragment.newInstance(position + 1))
                    .commit();
            break;
        case 1:
            fragmentManager.beginTransaction()
                    .replace(R.id.container, RedeemFragment.newInstance(position + 1))
                    .commit();
            break;
        case 2:
            fragmentManager.beginTransaction()
                    .replace(R.id.container, MyAccountFragment.newInstance(position + 1))
                    .commit();
            break;
        case 3:
            ParseUser.logOut();
            presentLoginActivity();
            break;
    }

and the error is on the line:

case 0: 
fragmentManager.beginTransaction()
                    .replace(R.id.container, ReviewFragment.newInstance(position + 1))
                    .commit();

and the error reads:

Wrong second argument type. Found: 'blah.blah.blah.MainActivity.ReviewFragment', required: 'android.support.v4.app.Fragment'

The CameraFragment is from cwac-camera-0.6.12.jar

public static class ReviewFragment extends CameraFragment

    /**
     * The fragment argument representing the section number for this
     * fragment.
     */
    private static final String ARG_SECTION_NUMBER = "section_number";

    /**
     * Returns a new instance of this fragment for the given section
     * number.
     */
    public static ReviewFragment newInstance(int sectionNumber) {
        ReviewFragment fragment = new ReviewFragment();
        Bundle args = new Bundle();
        args.putInt(ARG_SECTION_NUMBER, sectionNumber);
        fragment.setArguments(args);
        return fragment;
    }

    public ReviewFragment() {
    }

    ...
}

I know that the CameraFragment is android.app.Fragment and I've tried changing the getSupportFragmentManager(); to getFragmentManager(); and change all the other Fragment subclasses to subclass of android.app.Fragment but it still doesn't work. Ideas?

My CWAC-Camera library has two fragment implementations:

  • one for native API Level 11+ fragments
  • one for SherlockFragment, for the ActionBarSherlock action bar backport, for historical reasons

It does not contain a fragment that simply extends the fragment backport's Fragment class.

That being said, creating your own should take just a couple of minutes. Copy this class into your project and change it to extend android.support.v4.app.Fragment instead of SherlockFragment. In a quick scan of the code, I don't see any other changes that would need to be made.
