Without using the delete, is possible to update a Notification Channel Importance level after it was created?

Without deleting the channel.

After created a notification channel on Android, is that possible to update the importance level of a specific channel though application update? Just calling the createNotificationChannel again or reinstalling the app is not being enough.

Solution

  • No, it's not possible.

    As explained in the documentation:

    You can't programmatically modify the behavior of a notification channel after it's created and submitted to the notification manager; the user is in charge of those settings after creation.
