Basic Android Loader implementation, accompanying blog post: http://www.recursiverobot.com/post/60331340133/very-simple-example-of-a-loader-and-loadermanager-in

DumbLoader.java

public class DumbLoader extends CursorLoader {
    private static final String TAG = "DumbLoader";

    public DumbLoader(Context context) {
        super(context);
    }

    @Override
    public Cursor loadInBackground() {
        // this is just a simple query, could be anything that gets a cursor
        return DummyData.getItems();
    }
}

initialize.java

public class MainActivity extends FragmentActivity implements LoaderManager.LoaderCallbacks<Cursor> {
    CursorAdapter mAdapter;
    
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // omitted for brevity ...
        getSupportLoaderManager().initLoader(LOADER_ID, null, this);
    }
}

LoaderCallbacks_Cursor.java

@Override
public Loader<Cursor> onCreateLoader(int i, Bundle bundle) {
    return new DumbLoader(this);
}

@Override
public void onLoadFinished(Loader<Cursor> cursorLoader, Cursor cursor) {
    // mAdapter is a CursorAdapter 
    mAdapter.swapCursor(cursor);
}

@Override
public void onLoaderReset(Loader<Cursor> cursorLoader) {
    mAdapter.swapCursor(null);
}
