This is on a Nexus 5X with Android 8.0.0, targeting API 26.

When creating a Notification Channel

NotificationChannel mChannel = new NotificationChannel(channel_id, "Channel 1", NotificationManager.IMPORTANCE_DEFAULT);

Android actually registers it as

NotificationChannel mChannel = new NotificationChannel(channel_id, "Channel 1", NotificationManager.IMPORTANCE_HIGH);

This means that sounds are played by default, while they should not get played by default at importance level NotificationManager.IMPORTANCE_DEFAULT.

When I then go into the Notification Settings via a long-press on the notification, and click on "all channels", I see that channel having "acoustic signal" enabled (translating from German). When I press on that channel to get more settings I can read "Importance: High: Acoustig Signal"

When I now turn that Notification off by switching the toggle above the beforementioned message "Importance: High: Acoustig Signal", and then on again, then the message changes to "Importance: Middle: No sound" This is what NotificationManager.IMPORTANCE_DEFAULT actually is, the middle setting.

If I create the channel with NotificationManager.IMPORTANCE_MIN, then all is OK, it is a "low importance channel".

This really needs to get fixed ASAP. It turns out that using `NotificationManager.IMPORTANCE_MIN` is not a feasible workaround because that will cause the Notification to get inserted into a COLLAPSED Notification Channel Group, making it very inaccessible.

The behavior is exactly the same as if I had changed it manually from default (middle) to high. When you do that, and then disable and re-enable the channel, it will go back to the default (middle) setting.

Also, keep in mind that just changing the `NotificationManager.IMPORTANCE_xxx` value doesn't change it on an already existing channel.

Turns out that using `NotificationManager.IMPORTANCE_LOW` will disable the sound and not collapse the item. Yet the problem with the `NotificationManager.IMPORTANCE_DEFAULT` getting upgraded to a `NotificationManager.IMPORTANCE_HIGH` is still there.

Keep in mind that previous Android versions did not play a sound by default.

Actually, when I use `NotificationManager.IMPORTANCE_LOW` then I see that it is labeled as "Importance: Middle: No sound", and when I toggle it off and on, it stays at "Importance: Middle: No sound".

This means that there is a confusion there. Then it should mean that when creating a channel `NotificationManager.IMPORTANCE_DEFAULT`, it doesn not get upgraded to a `NotificationManager.IMPORTANCE_HIGH`, but AFTER TOGGLING it gets downgraded to `NotificationManager.IMPORTANCE_MIN`, yet the text indicates that `NotificationManager.IMPORTANCE_DEFAULT` is presented to the user as "High", and what is presented to the user as "Middle" is actually a `NotificationManager.IMPORTANCE_LOW`

Please provide the information requested in

to investigate further.

so...@gmail.com <so...@gmail.com> #9Sep 6, 2017 09:49AM

I would if I found some time.

The steps to reproduce can be inferred from the problem description. It happens 100% of the time. The expected behaviur is clearly defined as well as the current output.

I'm sorry that I don't have time to provide you a sample application. I am not affected by this problem because in my app I don't have the need for any other setting than NotificationManager.IMPORTANCE_LOW, which isn't affected by this issue.

It could be a problem for those who use NotificationManager.IMPORTANCE_DEFAULT

Once again, my apologies for only pointing out this problem.

I have the same issue on Nexus 6P and user report about this problem on Pixel XL.
