Not receiving background notifications on Android

[dovahkiin98]

I'm using the latest version of OneSignal for flutter (3.3.0).

As far as I know, OneSignal uses Firebase to send notifications to mobile, but for some reason, it only works while the app is in the foreground?

If you close the app then swipe it, or force close it, you never receive a notification. I even tried implementing the NotificationExtender, still nothing.

In Firebase, the notification is supposed to be handled by the system, but OneSignal doesn't seem to handle background notifications when the app is terminated.

Any solution to that?

@dovahkiin98 Thanks for reporting, you do not need to setup the OneSignal NotificationServiceExtension in order for notifications to display.

How are you "force closing" the app?

Could you capture the full logcat from the device when you send a notification? (Do not filter, make sure it show verbose as well, and not limited to your app so it shows system entries)

Could you share the Android versions and device models you have tested this scenario on?

@jkasten2 Either with the Android's "Force Close" in the settings, or simply just swiping the application in the Recent Apps
