Application context

An application context is a set of data that identifies an application’s tasks, where those tasks originate, and how those tasks are configured. On websites, an application context is a type of browsing context — data created when visitors use a browser to display content, like when they select a deep link.

As a developer, you might use an application context to gather information about how your apps use resources or to limit how your apps are used. An application context also provides valuable data if you’re trying to diagnose an application problem in specific circumstances, such as a website unexpectedly crashing on mobile devices or a buggy page.
