Cursor for listview in a fragment

How can i use a cursor inside a fragment? Here is the snippet of a cursor i want to setup but it says managedQuery is undefined:

Fragment1.java

private List<String> getMp3FilesFromSDCard() {
    //here we get the list of songs stored on the SD card and we update our singleton class     
        List<String> result = new ArrayList<String>();

        SingletonPlaylist playlist;

        playlist = SingletonPlaylist.getInstance();

        Uri uri = MediaStore.Audio.Media.EXTERNAL_CONTENT_URI;
        Cursor cursor;
        String[] projection = 
        {
            MediaStore.Audio.Media._ID,
            MediaStore.Audio.Media.ALBUM,
            MediaStore.Audio.Media.ARTIST,
            MediaStore.Audio.Media.TITLE,
            MediaStore.Audio.Media.DATA,
            MediaStore.Audio.Media.DISPLAY_NAME
        };

        String selection = MediaStore.Audio.Media.IS_MUSIC + " != 0";


        cursor = this.managedQuery(uri, projection, selection, null, null);

        cursor.moveToFirst();

        while (cursor.moveToNext())
        {
            result.add(cursor.getString(5));
            playlist.addSong(new Song(cursor.getString(0),cursor.getString(1),cursor.getString(2),cursor.getString(3),cursor.getString(4),cursor.getString(5)));
        }


        return result;
    }

How can i fix this?

getActivity().getContentResolver().query(uri, projection, selection, selectionArgs, sortOrder)

The best way to use listview with cursor adapter is to use Loaders

It allow you to manage cursor by fragment and making query in background
