Wrap-Up

Location and subscription resources are passive activities that allow your software to act as a background service. Your apps can take actions based on what users do, without necessarily requiring that the user take an active role. The sole outliers here are custom menu items, which the user will actively choose, and your subscription will allow your app to produce a response when notified by Mirror.
