我在我的Xamarin表单应用程序中使用Google Firestore，在将Xamarin.Firebase.Firestore Nuget包更新到最新版本后，我无法再在Android上调试我的项目。
我创建了一个新的Xamarin Forms项目，首先检查错误是由于我的代码还是由于Nuget包本身的问题。
然后我安装了Xamarin.Firebase.Firestore Nuget包，很快发现问题不在我的代码上，而是在Nuget包上。
如果您正在尝试安装Xamarin.Firebase.Firestore Nuget软件包，但您尚未安装Xamarin.AndroidX.Core和Xamarin.AndroidX.Browser Nuget软件包，它将显示“无法添加Xamarin.Firebase.Firestore”并显示一条很长的错误消息。这是非常恼人的，因为它给你一本小说阅读，而不是简单地显示一个提示，安装NugetPackages作为依赖旁边的父Nuget包裹。
然后为了安装Xamarin.AndroidX.Browser Nuget套件，您需要先安装Xamarin.AndroidX.Core Nuget套件。如果您没有先安装Xamarin.AndroidX.Core Nuget套件，您会收到另一个长的错误消息，告诉您需要安装它。
在我安装了所有三个Nuget软件包并尝试运行我的Android项目后，我收到以下错误消息：

The error refers to Xamarin.Google.Guava so I thought installing Xamarin.Google.Guava individually would solve the issue but not at all; I am still getting the same error.
Could someone please help me? There is no way I am the only person this is happening to.
