Description xamarinbugzilla 2016-09-29 16:30:27 UTC
I created a blank phone ContentPage then add a date picker in a stack layout to it like:

  <StackLayout VerticalOptions="Center" HorizontalOptions="Center">

Setting the preview to iOS mode - I see a date picker with today's date - setting the preview to "Android" gives me exceptions.
Comment 1 xamarinbugzilla 2016-09-29 17:14:15 UTC
It doesn't display a TimePicker either. It displays :'(
Comment 2 Kyle White 2016-10-07 02:28:44 UTC
Created attachment 17922 [details]

Able to reproduce in recent master so I'll confirm the bug. 

Neither DatePicker or TimePicker work in the Android preview, but do work for iOS (as mentioned above).

	<StackLayout VerticalOptions="Center" HorizontalOptions="Center">

Moving to C9 milestone to track for stable release of this feature.
Comment 4 Dominique Louis 2016-10-25 16:49:13 UTC
DatePicker and TimePicker controls are not currently supported for previewing under Android. They are supported under iOS. We are awaiting an appropriate fix from the Forms Team for this to work under Android when previewing.

The error here is:

PR: https://github.com/xamarin/Xamarin.Forms/pull/503
Comment 7 Alan McGovern 2016-11-03 11:14:37 UTC
(probably) better PR: https://github.com/xamarin/Xamarin.Forms/pull/504
Comment 8 Alan McGovern 2016-11-18 11:14:30 UTC
This is resolved and will require a new Xamarin.Forms release. I believe it will be included in the 2.3.4 release series.

Jeremie, can i leave this one with you?
Comment 15 Alan McGovern 2017-01-13 10:53:22 UTC
Jeremie patched XS (to work around an x.a desktop limitation) and xamarin-android (to fix a broken p/invoke):



Once these commits are backported to the relevant C9 branches it will *probably* work.

This is should now be fixed across the board in C9 (both XS / XVS).
