Probably not, in your case, since you said you didn't want the alarm to go off while the device was asleep. > My widget currently has a service with a function called "buildUpdate" that > returns a RemoteViews object. > To enable 5 minute updates, I need to: > - Add a new BroadcastReceiver class that overrides the onReceive function, > calls my "buildUpdate" function and updates my app widget. > - Add code to the onStart function of my service that creates the > AlarmManager intent and starts it up. > > Is this even close? Well, it's in the ballpark, at least. Depending on how long buildUpdate() takes, you may wish to consider delegating that work to an IntentService -- onReceive() is called with foreground priority on the main application thread, so you really want it to be snappy. Whether onStart() is the right place/time to set up your AlarmManager is difficult for me to say, since I don't know your app. > By the way, I have your book "Beginning Android 2" and another book on > Android development and neither one has much coverage of App Widgets, if any > at all.

But my app widget and AlarmManager coverage is in one of my books, just not the one you have.
