Fragments are meant to be reusable components of applications. You should not be using them as singletons, instead you should implement Fragment.SavedState or onSavedInstanceState.

public class YourFragment extends Fragment {

    // but here is how to save state
    @Override
    public void onSaveInstanceState(Bundle outState) {
        super.onSaveInstanceState(outState);
        outState.putInt("curChoice", mCurCheckPosition);
    }
    @Override
    public View onCreateView (LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        // savedInstanceState will have whatever you left in the outState bundle above
    }
}
