[android help] I'm unable to call a Fragment within onTabSelected of another Fragment that implements ActionTab Listener

I am trying to create a Fragment that has a ListView in the content section, as a default view. There are ActionBar tabs to this view. I'm able to create that so far.

The LaunchListFragment Code

public class LaunchListFragment extends ListFragment implements ActionBar.TabListener {
public static  String LIST_TYPE = "invalid";
GenericListData g_data[] = null;
   private ViewPager mViewPager;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
    View result = inflater.inflate(R.layout.fragment_launch_list,
            container, false);

    setActionTabs();
    setList();
    return (result);
}

public static LaunchListFragment newInstance(String type) {
    LaunchListFragment frag = new LaunchListFragment();
    Bundle args = new Bundle();
    LIST_TYPE=type;

    args.putString(LIST_TYPE, type);
    frag.setArguments(args);

    return (frag);
}

What I wanted is, when you click the onTabSelected(), would like to change the views and I am using PagerFragment with views generated using an FragmentPagerAdapter

@Override
public void onTabSelected(Tab tab, android.app.FragmentTransaction ft) {

       getChildFragmentManager().beginTransaction()
       .add(android.R.id.content,
            new PagerFragment()).commit();
}

The trouble is, I can't use getChildFragmentManager or getFragmentManager to call the PagerFragment, I get compilation errors to change the PagerFragment to app.Fragment. Even if I change that, it still complaints.

I suspect there is some sort of clash between support.Fragment and app.Fragment.

Is there a different way of approach to acheive this other than using nested Fragments?

Any help appreciated.
