You can always maintain an error queue, so if you notice some errors before the activity is attached, you can propagate them back to the Activity. I've done this before, and had success doing so. (In fact, we do this a fair amount in the security libraries we write for our projects here, because of the nature of when services are bound and when they are needed, etc...)
