    Necesito que mi aplicación tenga una caducidad o un trial de 30 días, hice una comparación de fechas con la fecha del dispositivo. El problema es si el dispositivo cambia la fecha, la aplicacion seguira funcionando...
    como se podria hacer para que esto no sucediera?

    Sub Activity_Create (FirstTime As Boolean)
    Activity.LoadLayout ("INICIO")
    Dim ahora, hoy, caduca, plazo tan largo
    'Atención es: mm / dd / aaaa
    caduca = DateTime.DateParse ("22/03/2019")
    hoy = DateTime.DateParse ( (ahora))
    plazo = caduca - hoy
    Si plazo <= 0 entonces
    Msgbox ("El programa ha caducado.", "Caducidad")
    Terminara si
    End Sub
