Android Question Firebase error in foreground

[José Daniel Pozo Zamora]

Hi everyone,
I have a problem, the firebase messages work fine when the application is in the background, but when it is in the foreground throw this error and close the application.
Thanks for your help beforehand

FirebaseMessaging not found.

my code :

Dim n As Notification
    n.Initialize
    n.Icon = "icon"
    n.Number = 1
    n.Light=True
    n.Sound=True
    n.Vibrate=True
    n.AutoCancel = True
    If Message.GetData.Get("message") <> Null Then
        Try
            n.SetInfo( Message.GetData.Get("titulo"), Message.GetData.Get("body"), Main)
            n.Notify(Message.GetData.Get("id"))
        Catch
            Log(LastException)
        End Try
    End if

Are you sending the message with the B4J code?

Hi,
I use this example: https://www.b4x.com/android/forum/t...s-firebase-cloud-messaging-fcm.67716/#content

How are you sending the message? With the B4J code from that link?
Or with Firebase console?
