I'll like to play a custom sound on notification so i made a little change based on https://www.b4x.com/android/forum/t...e-for-local-or-scheduled-notifications.54940/
B4X:
Sub LocManager_LocationChanged (Location1 As Location)
    'Check position
    p1.Initialize2("+42.0559340","+13.9242163")
    p3.Initialize2(Location1.Latitude,Location1.Longitude)
    Dim Distance As Float = p1.DistanceTo(p3)
    'Log("Distance is "&Distance&" meters")
    If Distance < 1000 Then
        label4.Text=NumberFormat(Distance,2,2)  & " metri"
    Else
        label4.Text="Too far..."
    End If
    ControllaPosizione(Distance)
End Sub
Sub ControllaPosizione(distanza As Float)
    If distanza<=20
            'Sending notification
            App.RegisterUserNotifications(True, True, True)
            Dim n As Notification
            n.Initialize(DateTime.Now)  
            Dim no As NativeObject = n
            n.PlaySound = True
            n.AlertBody = "My messagei."
            n.Register
            If App.OSVersion >= 8.2 Then  
                no.SetField("alertTitle", "Check point")
                'Custom sound
                no.SetField("soundName", "ring2.wav")
            End If
            MostraTesto1.RootPanel.LoadLayout("ShowInfo")
            NavControl.ShowPage(MostraTesto1)
            myPhone.Vibrate
            mp1.Initialize(File.DirAssets,"ring.mp3","MPlayer")
            mp1.play
            distanza=0
    End If
End Sub
Unfortunately i hear only the default notification sound. In post 54940 i can read
You should run this code before you register the notification (the code itself is correct).
but i don't understand where i have to move/put the right code :(
Furthermore when i install the app on the phone the first time appears correctly a request to use gps location, but for notification the request for allow or not the request appears only first time that there is a notification, but if the smartphone it's not at hand i don't receive any notification except the one 'do you want to allow notifications'?
So it's possible to request directly at installation 'do you want to allow notifications'? changing/adding a row somewhere, my be in Project Attributes?
