The worker object provides a live data object. It's exactly the same kind of live data object you might work with in a view model. The live data object can publish information, and your user interface can observe it and react. First I'll set up code to be notified when a task has completed successfully. I'm going to be using the WorkManager object more than once, so I'll change this code a bit so I'm declaring it and I have a single variable to work with. Now I'll add code to observe the request.
