Android Question Custom Notification Ringtone In Firebase Notification

[hongbii]

Hi all,
I'm using the Firebase Push Notification and NB6 mentioned inhttps://www.b4x.com/android/forum/threads/nb6-notifications-builder-class-2018.91819/#content
I implement the code in the fm_MessageArrived in FirebaseMessaging Service module.https://www.b4x.com/android/forum/t...s-firebase-cloud-messaging-fcm.67716/#content

Dim rp As RuntimePermissions
        Dim folder As String = rp.GetSafeDirDefaultExternal("shared")
        Dim FileName As String = ringtone
        'copy the file to the shared folder
        File.Copy(File.DirAssets, FileName, folder, FileName)
        Dim n As NB6
        n.Initialize("Channel1", Application.LabelName, "HIGH")
        n.SmallIcon(LoadBitmapResize(File.DirAssets, "icon.png", 32dip, 32dip, True))
        'disable the default sound
        n.SetDefaults(False, True, True)
        'set custom sound
        n.CustomSound(CreateFileProviderUri(folder, FileName))
        Dim Notification As Notification = n.Build(Title, Body, "", Me)
        Notification.Notify(3)

The custom ringtone rang successfully when the app is in foreground but becomes phone's default ringtone when the app is closed.
*Before setting the targetSDK to 26, the custom notification ringtone is work probably for both situations.
The ringtone name is sent in both data and notification tray from server side:https://firebase.google.com/docs/cloud-messaging/concept-options

 var notification = new
            {
                to = key,
                data = new
                {
                    title = _title,
                    body = _message,
                    sound = ringtone,
                    device = deviceSerial,
                    mode = mode1,
                },
                notification = new
                {
                    title = _title,
                    body = _message,
                    sound = ringtone,  
                    device = deviceSerial,
                    mode = mode1,
                },
                priority = 10
            };

Is that anything I can do to let the notification rang with custom ringtone even the app is closed by the user?

It shouldn't matter whether the app is in the background or not.

Try it with a different channel id.
