protected override void OnActivityResult(int requestCode, Result resultCode, Intent data)
{
    base.OnActivityResult(requestCode, resultCode, data);
    if (requestCode == FiuuActivity.FiuuXDK && resultCode == Result.Ok)
    {
        Console.WriteLine("Fiuu result = " + data.GetStringExtra(FiuuActivity.FiuuTransactionResult));
        SetContentView(Resource.Layout.layout_fiuu);
        TextView tw = (TextView)FindViewById(Resource.Id.resultTV);
        tw.Text = data.GetStringExtra(FiuuActivity.FiuuTransactionResult);
    }
