问题 I am able to create push notifications, and to send the user to whichever Activity I want, but I notice that whenever the user lands on that Activity, the onCreate function does not get called.

问题 Now all methods related to navigation modes in the ActionBar class, such as setNavigationMode() ... are now deprecated.
