AppLaunchChecker
class AppLaunchChecker
This class provides APIs for determining how an app has been launched. This can be useful if you want to confirm that a user has launched your app through its front door activity from their launcher/home screen, rather than just if the app has been opened in the past in order to view a link, open a document or perform some other service for other apps on the device.
