The Sample App
The sample app for this chapter is called BackgroundTasks. This app demonstrates the two backgrounding approaches: completing a long-running task while the app is in the background, and playing audio continuously while the app is in the background. The user interface is very simple—it presents a button to start and stop background music, and a button to start the background task (see Figure 16.1).
