Android Question SDCalendarDialog crashed while scanning the control

[netnetnet]

Sorry to interrupt
This code was fine, but crashed after the addition of the SdCalendarDialog control.
Error location: V.tag

Dim no_list,weight_list As List
    no_list.Initialize
    weight_list.Initialize
    Try
        For Each v As View In Activity.GetAllViewsRecursive
            Select v.Tag
                Case "P"
                    no_list.Add(v)
                Case "Weight"
                    weight_list.Add(v)
            End Select
        Next
        For i = 0 To 99
            SQL_NO(i)=no_list.Get(i)
            SQL_WEIGHT(i)=weight_list.Get(i)
        Next
    Catch
        ToastMessageShow("Scan fail",True)
        But_Close_Click 'close
    End Try
