Use the standard Service class instead of IntentService, start your asynchronous task from the onStartCommand() callback, and destroy the Service when you receive the completion callback.

The issue with that would be to correctly handle the destruction of the Service in the case of concurrently running tasks as a result of the Service being started again while it was already running. If you need to handle this case, then you might need to set up a running counter or a set of callbacks, and destroy the Service only when they are all completed.
