I see, and that makes more sense. Thanks for the explanation. While using an AsyncTaskLoader wasn't completely necessary for what I'm doing, I have it all working and it wasn't complicated to get going. So I'll call that a win-win.
I did manage to solve the original intent of this question today by creating an AsyncTaskLoader that understands how to load in all of the data the fragments in my ViewPager need. Thanks for the direction, the app is behaving exactly how I'd like now. -- Chris Stewart On Mon, Nov 28, 2011 at 3:11 PM, Dianne Hackborn <hack...@android.com>wrote: > Loader is not a replacement for AsyncTask.
