try it with this code please
B4X:
Sub Activity_Create(FirstTime As Boolean)
    'Do not forget to load the layout file created with the visual designer. For example:
    'Activity.LoadLayout("Layout1")
    verso.Initialize("Verso")
    verso.getGeoInfo(50.8293765,6.4325835)
End Sub
Sub Verso_geoinfo(geo As GeoInfo)
    Log($"Verso_geoinfo(${geo})"$)
    If geo <> Null Then
        Log(geo.CityName)
        Log(geo.CountryCode)
        Log(geo.CountryName)
        Log(geo.isMajorPlace)
    End If
End Sub
