Java - pas rafraîchissant Android restartLoader feed - Stack Overflow

I am trying to refresh my ListView adapter with an updated feed. Below is the pasted code.

public class VideoBrowserListFragment extends ListFragment implements
    LoaderManager.LoaderCallbacks<List<MediaInfo>> {

 public VideoBrowserListFragment(){}

private VideoListAdapter mAdapter = null;



 public static String VIDEO_URL =
           "";



/*
 * (non-Javadoc)
 * @see android.support.v4.app.Fragment#onActivityCreated(android.os.Bundle)
 */
 public void refreshweather(){
     VIDEO_URL ="Weather Feed URL";
     getListView().setFastScrollEnabled(true);
        mAdapter = new VideoListAdapter(getActivity());
        setEmptyText(getString(R.string.no_video_found));
        setListAdapter(mAdapter);
        setListShown(false);        
        getLoaderManager().initLoader(0, null, this);
        System.out.println("Madapter"+mAdapter);
     }

 public void refreshnews(){


  VIDEO_URL =
            "News Feed URL";


           getLoaderManager().destroyLoader(0);
           mAdapter = new VideoListAdapter(getActivity());
            setEmptyText(getString(R.string.no_video_found));
           setListAdapter(mAdapter);
           setListShown(false);        
          getLoaderManager().restartLoader(0, null, this);




        }


@Override
public void onActivityCreated(Bundle savedInstanceState) {
    super.onActivityCreated(savedInstanceState);
    refreshweather();




}

@Override

}

@Override
public void onListItemClick(ListView l, View v, int position, long id) {

    MediaInfo selectedMedia = mAdapter.getItem(position);
    handleNavigation(selectedMedia, false);





}

private void handleNavigation(MediaInfo info, boolean autoStart) {
    Intent intent = new Intent(getActivity(), LocalPlayerActivity.class);
    intent.putExtra("media", Utils.fromMediaInfo(info));
    intent.putExtra("shouldStart", autoStart);
    getActivity().startActivity(intent);
    System.out.println("VIDEO URL"+VIDEO_URL);       

    refreshnews();
    System.out.println("VIDEO URL"+VIDEO_URL);

}

/*

@Override
public Loader<List<MediaInfo>> onCreateLoader(int arg0, Bundle arg1) {

    return new VideoItemLoader(getActivity(), VIDEO_URL);

}




public static VideoBrowserListFragment newInstance() {
    VideoBrowserListFragment f = new VideoBrowserListFragment();
    Bundle b = new Bundle();
    f.setArguments(b);
    return f;
}

public static VideoBrowserListFragment newInstance(Bundle b) {
    VideoBrowserListFragment f = new VideoBrowserListFragment();
    f.setArguments(b);
    return f;
}

}

VIDEO_URL is the link to the feed. I made it so it calls refreshweather() right away. I also made a function for refreshnews, which should restart the loader with a different VIDEO_URL. For testing purposes, i am calling refreshnews() when you click a list item. It refreshes the feed, but it still pulls the same weather feed and not the news. Shouldn't the new loader be pulling in the updated VIDEO_URL variable and feed after a listitem is clicked?

Anybody have an idea why? I am still a little new to android and java.
