Ok. That makes sense but brings it all back full circle.

It's clear that Application.onCreate is being called multiple times for
my app. It also seems that my preferences are being reset as a result
of that happening. But from everything that I am reading in this
discussion it would seem that should not be the case. I guess I have to
add some debugging code and have my user side-load it to see if I can
get some insight into the problem.

Incidentally, this is a fairly straighforward application with nothing
fancy. It uses an AppWidget class, one Activity, a Preference
Activity and a Service to do some work on behalf of the widget. So any
whatever is causing my problem it's not because I am being too fancy.
