One more thing:
Android uses the same Linux process for your WidgetProvider as well as
service that updates the widget (again, I'm assuming you followed the
Wikipedia sample).
The WidgetProvider will be created and invoked as necessary, this, in
turn, should cause your service to be started when you call
"startService(this, UpdateService.class)".
A task killer is likely to interfere with the first part of this
sequence - i.e. preventing the WidgetProvider from responding to update
events in the first place.

If your code is set up along the lines of the Wikipedia sample widget
(which it seems to be), and the widget's onUpdate invokes the service
with startService, then everything should be fine already.
StartService will, obviously, start the service as necessary.
If there are still problems updating the widget, ask your user to add
your service to the task killer's exclude list. Better yet, try to
educate the user about the evil nature of task killers, perhaps he/she
will stop using them altogether.

What is the correct way to ensure that a widget update service is
restarted if it has been killed?
In my widget, I start the service in the onUpdate event, but if the
widget and service are killed (by a task killer, for example), the
widget restarts, but the service doesn't.
