android - Xamarin.Forms.Device.get_PlatformServices() 崩溃

Question

我正在开发带有内部 Webview 的 Xamarin.Forms 应用程序。在我的这个 Android 中有一些崩溃，显示在 Google Play 控制台中。有人可以帮我弄这个吗？

错误信息

我认为错误发生在 OnCreate 方法内部，但我不知道如何解决它：

MainActivity.cs

protected override void OnCreate(Bundle savedInstanceState)
{
   TabLayoutResource = Resource.Layout.Tabbar;
   ToolbarResource = Resource.Layout.Toolbar;

   FormsWebViewRenderer.Initialize();

   base.OnCreate(savedInstanceState);
   global::Xamarin.Forms.Forms.Init(this, savedInstanceState);

   AnimationViewRenderer.Init();

   RequestedOrientation = !IsTablet ? ScreenOrientation.SensorPortrait : ScreenOrientation.SensorLandscape;

   Android.Webkit.WebView.SetWebContentsDebuggingEnabled(true);

   StartActivity(typeof(StartActivity));
}

开始活动.cs

 protected override void OnCreate(Bundle savedInstanceState)
        {
            base.OnCreate(savedInstanceState);

            LoadApplication(new App());

            RequestedOrientation = !IsTablet ? ScreenOrientation.SensorPortrait : ScreenOrientation.SensorLandscape;
        }
