Hello @vargaz.
Could this issue be related to Mono?
Thanks!
That might be related to https://github.com/xamarin/xamarin-android/pull/1967, which was fixed in master.
To confirm that, could you create a project which would reproduce that issue so that I can try it locally?
Actually it should have been already fixed in 15.8.2, so I guess it is different problem. Anyway, having project which reproduce the issue would really help.
I think I found the issue in our code, preparing a fix.
Hi @radekdoulik.
Do you know when we can get a new release with this fix?
Or is there any guide I can test the fix?
Thanks!
Checked against this version https://jenkins.mono-project.com/view/Xamarin.Android/job/xamarin-android/1222/Azure/ and issue gone.
Thanks
@NikolayKash I think it will be available in Dev16.0 Preview 2, as I see the commit included here:
