在构建 Xamarin Android 项目时，我们偶尔会遇到这些异常。有什么想法如何消除片状吗？这对我们来说是可以解决的还是看起来像 Xamarin Android bug？

我们注意到构建代理已选择有效的 $(TargetFrameworkVersion) 并且所需的 android api 级别已安装在 $(AndroidSdkDirectory)\platforms 中。我们使用 Android 10 作为目标框架版本，SDK 29 安装在 /Users/Shared/Development/Android/sdk/platforms/android-29 中。

最佳答案
从版本 0.7.1 更新包 Xamarin.Build.Download 后。到 0.8.0 我们无法重现此错误。我们还更新了将此库作为依赖项的包。在我们的例子中，这些是 Xamarin.Firebase.Analytics 和 Xamarin.Android.Crashlytics。
