Android Question java.lang.IllegalArgumentException: Unknown pattern character 'u'

[Shay]

I want to get number of day (1=Sunday, etc..)
According to this:
http://docs.oracle.com/javase/7/docs/api/java/text/SimpleDateFormat.html

Sub FindDayOfWeek
   
    Dim Today As Int
   
    DateTime.DateFormat = "u"
    Today = DateTime.Date(DateTime.Now)
    Log (Today)
   
End Sub

Getting error on "u" line

Error occurred on line: 61 (OpenJobsCleaning)

Sub FindDayOfWeek as Int
    Dim Date As long = DateTime.Now
    return DateTime.GetDayOfWeek(Date)
End Sub

Thanks,but isn't a bug?

also I got "7" and I saw on different thread here that is was suppose to give 6 (0=Sunday)

 

[DonManfred]

also I got "7"

https://www.b4x.com/android/help/core.html#datetime_getdayofweek

Returns the day of week component from the ticks value.
Values are between 1 to 7, where 1 means Sunday.
You can use the AHLocale library if you need to change the first day.

Thanks again
