Android Question Icon app always show in status bar

[uniplan]

HI, i use firebase to send notification to app.Thi is my code to show thw notification:

Dim n As Notification
    n.Initialize()
    n.Icon = "icon"
    
n.SetInfo2(titolo_push,messaggio_push,id_notifica,Main)
                n.Notify(id_notifica)
                n.Vibrate=True
                n.AutoCancel=True

In the Android 8 i receive correctly the notification,but the notification window does not go down...
but the most problem is that I show always another notification with app name and i don't know how i can remove it..
the notification is always displayed until I close the app
Ho i can solve it?
Thank you

Hiding your project is a great help for us to help you. ZERO HELP to be exactly..
Are you using a foreground service?
