android - I'm working with ListFragment but I'm having some problems with LoaderManager -

i'm making music player , i'm trying display artist names using listfragment. here code:

import android.app.listfragment; import android.database.cursor; import android.os.bundle; import android.provider.mediastore; import android.support.v4.app.fragmentactivity; import android.support.v4.app.loadermanager; import android.support.v4.content.cursorloader; import android.support.v4.content.loader; import android.support.v4.widget.cursoradapter; import android.view.layoutinflater; import android.view.view; import android.view.viewgroup;  public class albumsfragment extends listfragment implements loadermanager.loadercallbacks < cursor > {      albumsadapter madapter;      @     override     public view oncreateview(layoutinflater inflater, viewgroup container, bundle savedinstancestate) {         view myfragmentview = inflater.inflate(r.layout.tabs_list, container, false);         return myfragmentview;     }       @     override     public void onactivitycreated(bundle savedinstancestate) {         super.onactivitycreated(savedinstancestate);          madapter = new albumsadapter(getactivity(), null);         setlistadapter(madapter);          getloadermanager().initloader(0, null, this);     }       static final string[] album_summary_projection = {         mediastore.audio.albums._id, mediastore.audio.albums.album     };        public loader < cursor > oncreateloader(int id, bundle args) {         string select = null;         return new cursorloader(getactivity(), mediastore.audio.albums.external_content_uri, album_summary_projection, select, null, null);     }        public void onloadfinished(loader < cursor > loader, cursor data) {         madapter.swapcursor(data);     }        public void onloaderreset(loader < cursor > loader) {         madapter.swapcursor(null);     } }   

i error saying: method initloader(int, bundle, loadermanager.loadercallbacks) in type loadermanager not applicable arguments (int, null, albumsfragment)

did see in imports ?

import android.support.v4.app.fragmentactivity; import android.support.v4.app.loadermanager; import android.support.v4.content.cursorloader; import android.support.v4.content.loader; import android.support.v4.widget.cursoradapter; 

it means using support version of loadermanager.

so should replace

 getloadermanager().initloader(0, null, this);     

with

 getsupportloadmanager().initloader(0, null, this);
