Droid项目中引用的.NET Standard 2库中的HttpClient实现

Question

I have an instance of HttpClient in a .NET Standard 2 library and the Droid project references the library. In the Droid project HttpClient implementation is set to Android. Will the HttpClient implementation use java.net.URLConnection or the HttpClientHandler?

I want it to use the native HttpClient. In case it uses the managed HttpClientHandler, do I need to add a special case for Android in my shared code library like this:

// if we're on any other platform
HttpClient client = new HttpClient()
// if we're on Android    
HttpClient client = new HttpClient(new Xamarin.Android.Net.AndroidClientHandler ())

If you specify in the project options the type of client, you just need to initialize the HttpClient(), without specifying it's type.

From the docs:

// This will use the default message handler for the application; as
// set in the Project Options for the project.
HttpClient client = new HttpClient();

// This will create an HttpClient that explicitly uses the CFNetworkHandler
HttpClient client = new HttpClient(new CFNetworkHandler());

// This will create an HttpClient that explicitly uses NSUrlSessionHandler
HttpClient client = new HttpClient(new NSUrlSessionHandler());
