AsyncTaskLoader - onLoadFinished() is not called

Question

I have an AsyncTaskLoader:

public class FakePdfLoader extends AsyncTaskLoader<Integer> 

That I start with:

getSupportLoaderManager().initLoader(0, args, this);

from an activity:

MyActivity implements LoaderManager.LoaderCallbacks<Integer>

But my method:

@Override
public void onLoadFinished(Loader<Integer> loader, Integer data) {
    Log.d("TEST", "finished loading " + data);
}

is never called. I know the ATL does doInBackground() and also reaches deliverResults() and it definitely delivers an Integer. Could it be that the return type Integer causes a problem here?

EDIT: The Integer has nothing to do with it, I tested that.

Answer 1

Oh boy, I'm so stupid sometimes. In my AsyncTaskloader, I overrode deliverResult, had blindly copied it from Google's example.
