How to properly update a notification post api 11?

Question

• Before Notification.Builder came into existence the way to update a notification that was already in the notification tray was to call setLatestEventInfo()

Answer 1

What you are doing is correct, you're just missing the flags you can set. I don't know your particular notification implementation but you might consider using:

setOngoing(boolean ongoing)

or

setOnlyAlertOnce(boolean onlyAlertOnce)
