I'm then wanting to take the statusBarNotification object received and broadcast it.

阅读更多关于 Fragments and Notifications: Target different Activities from Notification; depending on screen configuration

问题 Question: How to decide what Activity a Notification should launch if the target might depend on the configuration (screen size, orientation etc); as is often the case when one uses Fragment s?
