I want to know the status without broadcasting it to the room. Changing to lowest would still show up in the notification tray but would not disturb you. See i. That's how I did it on Android 8, but I can't seem to find it on Android 9.
I've recently upgraded. Notifications can include an animated progress indicator that shows users the status of an ongoing operation. Figure 4. The progress bar during and after the operation. If you can estimate how much of the operation is complete at any time, use the "determinate" form of the indicator as shown in figure 4 by calling setProgress max, progress, false. The first parameter is what the "complete" value is such as ; the second is how much is currently complete, and the last indicates this is a determinate progress bar.
As your operation proceeds, continuously call setProgress max, progress, false with an updated value for progress and re-issue the notification. At the end of the operation, progress should equal max.
You can either leave the progress bar showing when the operation is done, or remove it. In either case, remember to update the notification text to show that the operation is complete. To remove the progress bar, call setProgress 0, 0, false.
To display an indeterminate progress bar a bar that does not indicate percentage complete , call setProgress 0, 0, true. The result is an indicator that has the same style as the progress bar above, except the progress bar is a continuous animation that does not indicate completion.
The progress animation runs until you call setProgress 0, 0, false and then update the notification to remove the activity indicator.

However, you are not required to set a system-wide category and should only do so if your notifications match one of the categories defined by in NotificationCompat.

For example, an SMS app might display a notification that shows You have 3 new text messages , but hides the message contents and senders.
To provide this alternative notification, first create the alternative notification with NotificationCompat. Builder as usual. Then attach the alternative notification to the normal notification with setPublicVersion. However, the user always has final control over whether their notifications are visible on the lock screen and can even control that based on your app's notification channels. To update this notification after you've issued it, call NotificationManagerCompat.
If the previous notification has been dismissed, a new notification is created instead.

I've got a Nexus 4 and have been looking forward to update to Android 5. While playing with the notification control in Settings, I found that notifications could be hidden forever. Then I long-clicked on a download notification in the notification bar , clicked the info button and then locked the notifications.
But when I decided to have them back, there was no way to do so. If I tried this for any other app, such as Whatsapp, there is no problem. I suspect this has something to do with the fact that the Download app itself it's not locked, but it is another system app hidden in this menu. Click images for full size.
