Xamarin地图显示灰色瓷砖

Question

我是xamarin的新手，并致力于掌握基础知识。

一直关注本教程： https://docs.microsoft.com/en-us/xamarin/xamarin-forms/user-interface/map

从下面可以看出它看起来我可以请求，但我仍然有灰色瓷砖。什么可能导致这个？我的api密钥有问题吗？

public partial class MainPage : ContentPage
{

    private StackLayout stackLayout = new StackLayout();
    private Map map;
    public MainPage()
    {
        InitializeComponent();

        map = new Map(
        MapSpan.FromCenterAndRadius(
                new Position(35.184657, 33.353528), Distance.FromMiles(0.3)))
        {
            IsShowingUser = true,
            HeightRequest = 100,
            WidthRequest = 960,
            VerticalOptions = LayoutOptions.FillAndExpand
        };



        stackLayout.VerticalOptions = LayoutOptions.FillAndExpand;
        stackLayout.HorizontalOptions = LayoutOptions.FillAndExpand;

        stackLayout.Children.Add(map);

        Content = stackLayout;
    }

调试输出

实际上，我认为如果您的API密钥错误，您将无法导航到地图页面。我在一两个星期前碰到了这个。查看应用程序输出，您应该看到有关“联系谷歌地图服务器”的消息
