In latest VS 2017 15.8.4 I've Xamarin 4.11.0.756, Xamarin Designer 4.14.221, Xamarin Templates 1.1.116, Xamarin.Android SDK 9.0.0.19 and Xamarin.iOS and Xamarin.Mac SDK 11.14.0.13 in Windows 10 Pro 64bit. Before creating project I've installed with AndroidSDKManager.exe only Android 5.1 SDK - API 22. Well, I started creating new solution "TestApp" from template "Cross-Platform" -> "Mobile application (Xamarin.Forms)" and I'm selected template "Master-Detail" with Android, iOS and Windows (UWP) with .NET Standard. Then in project "TestApp.Android" in properties I've changed target platform to "Android 5.1" and set minSDKversion to API 21 and target SDK version to API 22. And now I try to compile and I get errors:

What I did wrong or what is missing?

c#xamarinxamarin.formsvisual-studio-2017cross-platform
use Android 8.1 or 9 Platform tools and set Minimum Android to 5.1 – magicandre1981
@magicandre1981 I've try this way, but my application don't run on my 22 API device - it is stating and exit at once. – amaranth
create a 5.1 Virtual Device in emulator and debug the app there to see what fails on 5.1 devices. – magicandre1981

First of all you should be having a latest version of monoandroid, 5.1 is a quite old one. The latest is 8.1 I think. You can try updating that first. Download latest Android SDK, change the target platform to be compiled using latest SDK.

Check this for refrence Xamarin - How to update Mono.Android version to resolve dependencies?

But if you want to use the 5.1 only, you will have to downgrade most of the nugets you are using, which includes Xamarin.Android.Support.Design too.
