The crash is only in release mode, both on a real device and Android Studio emulator

I mean I abandon this library because doesn’t suit my needing and has problems (but it works at your home so, peace and love). I come back to standard spinner and date picker. Thanks for your support.

The problem lies with the device. The DatePicker adds a large number of items to the list so that you can select 2 years into the past and 2 years into the future.
And can be solved by using the "MinDate" property before calling ".Create". And give this e.g. the value DateTime.Now, then the list is smaller and your device does not get into a memory problem.

I abandon this library because doesn’t suit my needing
If it doesnt suit your needing, then do it with the AS_WheelPicker with your own items?
Thanks for your support.
No Problem.

Understand.
why didn’t you give before this explanation if you knew it ?
I like much the appearance of your picker that looks like IOS style and I’m distributing the App for both platforms (better if it has the same look) but I have to abandon it for these reasons:
  1. We are in Italy and I want the date time is represented as we in Italy are used to
  2. In my application I can’t limit the time span. I could limit the future to today (there are no data to show for the future) but two years in the past is also not enough.

Because I had a lot to do privately and had no opportunity to check on the PC?
but two years in the past is also not enough.
Then a normal DatePicker is more suitable, as a user I would not want to scroll through over 730 days to select a date that is more than 2 years in the past.

Italy has the same date format as Germany. But it is simply not possible to redesign the whole thing in a view which is a 2 in 1 view so that everything is dynamic, especially if you can only work with index. A custom solution would be much better.

Hi dear.
I use rel. 3.23 WheelPicker and rel.1.15 As_WheelDateTimePicker
I have this code:
B4X:
Sub B4XPage_Appear
    
    AS_WheelDateTimePicker3.Date = DateTime.Now
    AS_WheelDateTimePicker3.Hour = DateTime.GetHour(DateTime.Now)
    AS_WheelDateTimePicker3.Minute = DateTime.GetMinute(DateTime.Now)
    
    AS_WheelDateTimePicker3.MinDate = DateTime.Now + DateTime.TicksPerDay
    AS_WheelDateTimePicker3.MaxDate = DateTime.Now + DateTime.TicksPerDay*5
        
        
    AS_WheelDateTimePicker3.MonthNameShort =      AS_WheelDateTimePicker3.CreateASWheelDateTimePicker_MonthNameShort("Gen","Feb","Mar","Apr","Mag","Giu","Lug","Ago","Set","Ott","Nov","Dic")
    AS_WheelDateTimePicker3.WeekNameShort = AS_WheelDateTimePicker3.CreateASWheelDateTimePicker_WeekNameShort("Lun","Mar","Mer","Gio","Ven","Sab","Dom")
    AS_WheelDateTimePicker3.Refresh
End Sub

The minimum date is respected, the maximum date continues regardless of the line code

B4X:
AS_WheelDateTimePicker3.MaxDate = DateTime.Now + DateTime.TicksPerDay*5

Where i wrong ?

Hi, please make a new thread for any questions you have. And please provide an example project that shows all your settings and the behavior. Thank you very much, have a good start into the week.
