While the IntentService class allows a service to be implemented with minimal coding, there are situations where the flexibility and synchronous nature of the Service class will be required. As will become evident in this chapter, this involves some additional programming work to implement.
In order to avoid introducing too many concepts at once, and as a demonstration of the risks inherent in performing time-consuming service tasks in the same thread as the calling application, the example service created here will not run the service task within a new thread, instead relying on the main thread of the application. Creation and management of a new thread within a service will be covered in the next phase of the tutorial.
