With Android v5 it works perfect, but with Android 9 I have this error.

Hello DonManfred

simple Public Sub



B4X:
Public Sub MostrarToast
    Dim fecha As String = $"Fecha : ${DateTime.Date(Main.FechaBD)& CRLF & "Hora : "} ${DateTime.Time(Main.FechaBD)}"$
    toast.Initialize("")
    toast.withGravity(toast.Gravity.TOAST_CENTER)
    toast.withTextColor(Colors.Blue)
    toast.withAnimation(toast.Animation.FLY)
    toast.withDuration(4000)
    toast.withOval(True)       
    toast.create(fecha)
    toast.Show                                                 
End Sub
