Whether you’re interested in building an advanced application or just want to add notifications to a basic application, you’ll find some essential topics in this chapter. After a broad review of advanced multistage applications, with an introduction to notifications and dashboards, you learned that advanced applications are based on an application assistant, which can handle external launch requests and potentially run in the background. You were also shown how to customize your application’s behavior when minimized, meaning switched out of the foreground view, and how to use the internal application notification chain to coordinate actions between assistants or share events and data.

With the techniques in this chapter, you should be able to move your application to the background, build a dashboard-only application, or use secondary card stages to support separate activities.
