Build pipeline for Xamarin.Android project targeting API 28

I'm trying to build a Xamarin.Android project targeting Android P (API 28) using Azure DevOps/VSTS. The build is failing because it doesn't have API 28 added to the Android SDK on the build server. How would I go about setting that up on the build server? On my local instance I would setup the Android SDK using Tools -> Open Android SDK Manager, but that process requires using the GUI which I don't have on the build server.

The exact build error is:

C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\MSBuild\Xamarin\Android\Xamarin.Android.Common.targets(627,2): Error XA5207: Could not find android.jar for API Level 28. This means the Android SDK platform for API Level 28 is not installed. Either install it in the Android SDK Manager (Tools > Open Android SDK Manager...), or change your Xamarin.Android project to target an API version that is installed. (C:\Program Files (x86)\Android\android-sdk\platforms\android-28\android.jar missing.)

If you have access to a command line and can navigate to the SDK path, you can download the android-28 platform via sdkmanager - Jon Douglas

I found success using windows-2019 Ensure you are using NuGet 5.8 (I know frustrating this isn't the error)

Are you using the Azure Pipelines hosted build agent? It should already have API 28 installed. If that's not working, please file an issue in that repo.

On a private agent, you can use Android's sdkmanager to install API 28.
