I would have expected this to be in onNewIntent(). Does this work in all
situations? (Chrome running / not running vs. Settings page / Notification rear)

[Michael van Ouwerkerk, 2015/02/25 19:00:19]

That's also what I expected, but I could find no way to trigger onNewIntent, it
always went via onCreate.

+            NotificationUIManager.launchNotificationPreferences(this, getIntent());
