Lets say you have a widget that displays the number of minutes remaining until Sunrise. The widget itself cannot, in its own context, determine its location for astronomical calculations since that takes too long. So we use a service to do the actual work of figuring out where we are and what time is Sunrise. The widget sets up an alarm so that its broadcast receiver gets a notification every 60 seconds (or configurable time period) so as to start the service and update the widget.
If I understand Mark's books and other sources correctly this should be the correct way to approach the problem - I hope! So how do I now handle the location issue? getLastKnownLocation() won't work, as pointed out, since there may not be one. So do I have the service set up a location listener to et the initial update and then only take new updates when the location changes by X miles? Or is the service not the correct place to have the listener? At every service start the service needs to know where it is so that it can update the time to sunrise in case we moved. So maybe what I really need is a one-shot quick location fix for the current location and not a listener. I don't care to know where I am unless I am ready to update the widget. Does any of this make sense?
