Android O - Notification Channels - Change Vibration Pattern or Sound Type

Question

With Android O we get the \"Notification Channels\".

As far as I understand that means that the user can\'t set

Answer 1

That is correct, once a channel is created you cannot make changes to it anymore.

You can't programmatically modify the behavior of a notification channel once it's created and submitted to the notification manager

What you would have to do delete the channel and create a new one with a different id
