Android SDK documentation says that startManagingCursor() method is depracated:
startManagingCursor()
This method is deprecated. Use the new CursorLoader class
The SimpleCursorLoader is a simple solution, however it doesn't support updating the loader when the data changes. CommonsWare has a loaderex library that adds a SQLiteCursorLoader and supports re-query on data changes.
