Is it possible to display notifications in the Now Bar using the MIT app?

MIT App Inventor Help

I've created an app that acts as a pedometer. When the screen is locked, it shows the distance you've walked as a notification. I want to display this in the new Now Bar as well. Is there a plugin for this?

It appears that this "Now Bar" is only available on Samsung devices running UI17?

Your AppInventor app will need to be receiving or generating notifications, probably running in the background.

Samsung probably provide a method to redirect app notifications to its Now Bar ?

No. Now Bar came with One UI 6.1. I think you're referring to Android 17.

4

Yes. It runs in the background. Using iToo services. Notifications can be sent, but they also need to appear in the Now Bar (live notifications).

Meant One UI 7

Anything there in Settings for either an app or Now Bar?

I asked Brave for you:

samsung android how to make app notifications appear on Now Bar

To make app notifications appear on the Now Bar in Samsung Android (One UI 7+), ensure the app is running and configure both system-level and app-level permissions.

1. Enable Now Bar and Select Apps
Navigate to Settings > Lock screen and AOD > Now bar. Tap View more (or See all in Live notifications) and toggle ON the switch for the specific app you want to display.

2. Configure App Notification Permissions
For the Now Bar to detect the app, you must enable specific permissions within the app’s notification settings:

  • Go to Settings > Notifications > App notifications.
  • Select the desired app.
  • Turn ON Allow notifications.
  • Turn ON Show on lock screen (or Show or hide content when locked).
  • Turn ON Live notifications (this is critical for real-time updates like timers or media).

3. Troubleshooting

  • Show Content: If the Now Bar shows only the app icon/name, go to Settings > Notifications > Lock screen and enable Show content when unlocked (or show notification content on the lock screen).
  • Notification Categories: If Manage notification categories is on for the app, ensure all required categories are toggled on within the app’s notification settings.
  • App Activity: The Now Bar only displays live updates while the supported app is actively running in the background.

Note: In One UI 8, any app can show live notifications via the Android 16 "Live Updates" API, but you must still enable the app in the Now Bar settings to display it.

There. That's what I was saying. How do you send notifications using the Live Notifications API? Is the melonnofication plugin sufficient for this? If so, how?

All apps that display live notifications can also display notifications in the now bar.
