This problem manifested itself for me with a CursorLoader returning a Cursor that was already closed:

android.database.StaleDataException: Attempted to access a cursor after it has been closed.

I'd guess this is a bug or an oversight. While moving initLoader() into onResume may work, what I was able to do was remove the Loader when I'm done with it:

To start the loader (in my onCreate):

  getLoaderManager().initLoader(MUSIC_LOADER_ID, null, this);

Then after I'm done with it (basically at the end of onLoadFinished)

  getLoaderManager().destroyLoader(MUSIC_LOADER_ID);

This seems to behave as expected, no extra calls.
