I have two examples of Intentservice. One is the Download example in the commonsware book. the other is at http://www.vogella.com/articles/AndroidServices/article.html#ser

Answer 1

How do I keep it running?

You don't. IntentService is designed to do a piece of work (or perhaps a few off a queue, if commands happen to come in rapidly), then shut down.

The service I am writing has to have events and listen for things.

Then you should not be using an IntentService. Use a regular Service, with your own background thread(s) as needed.
