I just looked at it. 1) They state that it is only an optimization and that you are not to rely on the method being called.
2) My design is a little too complex to use that elegantly. I do network calls from multiple activities and some dialogs on those activities, which need to chain to other actions upon completion. I'm learning about Services right now and I think that if I could have a network service that I can register a specific callback with, like a "User Updated" callback, it would work really well. When the service finishes updating a user, it simply notifies the user updated callback. It won't care if it was the original activity/dialog or a new one. Does that sound feasible?
