The latest Xamarin.Forms (3.5.0.129452, just released) requires, for Android Pie, the latest Android Support Library series (28.0.0.1). Upgrading all these in an Android project using Telerik will not build in VS 2017 until the ancient Xamarin.Android.Support.V8.RenderScript, not available in that series, is removed. Unfortunately Telerik requires that dll for some controls. Although the project can then build, it crashes on trying to use a dependent control.

To put it another way, it would seem Telerik needs to remove its dependencies on RenderScript, seeing that Xamarin has not seen fit to update it.

Hi David,

I am sorry to hear about there issues.

The Xamarin.Android.Support.v8.RenderScript library is required by Telerik.Xamarin.Android.Primitives.dll only with R3 2018.3 or earlier releases. In case you have updated to the latest versions of Xamarin.Forms and Telerik UI for Xamarin and you have updated all the Android Support Libraries to v 28.0.01 you should uninstall the Xamarin.Android.Support.v8.RenderScript library from the nuget packages.

The Required Android Support Libraries article in our documentation was updated and the changes will be live next week. I have added 300 Telerik points to your account as a small sign for bringing this to our attention.

Let me know if you have any additional questions or concerns.

Regards,
Didi

Thank you for the clarification. I have confirmed in my version of the Android project still using the earlier Xamarin Forms that RenderScript is no longer necessary. So, it seems, I must look elsewhere to explain the new crashes and the culprit does seem to be the new Xamarin Forms made breaking changes for my code. For instance one simple Android renderer that has nothing to do with Telerik now fails. I guess I'll be sticking with the older Xamarin Forms awhile longer.

Hello David,

We are aware of an issue that affects the RadListView and RadTreeView control of Telerik UI for Xamarin with version 3.5.0 of Xamarin.Forms and we have this logged in our feedback portal. You could follow the item on the provided link below in order to receive an email notification when there is a progress on it:

https://feedback.telerik.com/xamarin/1386786-listview-android-exception-is-thrown-when-building-with-xf-3-5

I can assure you that I have raised its priority and a fix for it will be provided in the next minor release. In this case, I could suggest you use the 3.4 version of Xamarin.Forms.

Let me know if you have any additional questions or concerns. 

Regards,
Didi
