When building a Xamarin Android project we sporadically get these exceptions. Any ideas how to remove the flakiness? Is this even solvable on our side or looks like an Xamarin Android bug?

We checked that the build agent has selected a valid $(TargetFrameworkVersion) and the required android api-level is installed in $(AndroidSdkDirectory)\platforms. We use Android 10 for the target framework version and SDK 29 is installed in /Users/Shared/Development/Android/sdk/platforms/android-29.

If you move your project from VS-for-mac to the VS windows. Rebuild you project, if this issue is still existed. Can you re-back to the previous version? – Leon Lu - MSFT
We do not have the infrastructure to switch to Visual Studio for Windows. – Christopher Stephan
Can you share a demo that could reproduce this issue? – Leon Lu - MSFT
We did not spend time in trying to find a small reproducible example yet. Based on this we try to update nuget packages that have dependencies Xamarin.Build.Download with a version smaller than 0.8.0. – Christopher Stephan
Thank you for your support. We could not reproduce the error after updating Xamarin.Build.Download to version 0.8.0. – Christopher Stephan

After updating package Xamarin.Build.Download from version 0.7.1. to 0.8.0 we could not reproduce this error. We also updated packages that had this library as a dependency. In our case these were Xamarin.Firebase.Analytics and Xamarin.Android.Crashlytics.
