iOS Question How to play a custom sound on notification (even in the background)

[sdesan]

As update and completion of https://www.b4x.com/android/forum/threads/background-location-tracking.50246/page-4#post-684135

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/

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?

So it's possible to request directly at installation 'do you want to allow notifications'?

Call App.RegisterUserNotifications in AppStart.

Have you put ring2.wav in Files\Special? Note that the file name is case sensitive.

Call n.Register after you set the sound.

Thank you Erel.
For notification i inserted

Private Sub Application_Start (Nav As NavigationController)
    App.RegisterUserNotifications(True, True, True)
   ....

For custom sound I moved ring2.wav from Files\SpecialFolder to Files\Special
It works.
Please correct in https://www.b4x.com/android/forum/t...e-for-local-or-scheduled-notifications.54940/

Yes. Manually put the sound file in Files\SpecialFolder.
