Xamarin表单中无法使用闪亮的地理围栏

问题描述

我实际上是在使用https://allancritchie.net/posts/shiny-geofencing为我的Xamarin表单应用程序实现地理围栏，但是在“ GeofenceDelegate.cs”中并没有遇到断点。

谁能告诉我我的代码出了什么问题？ 我正在android模拟器中进行测试。

using MyApp.Services.BackGroundJobs;
using Microsoft.Extensions.DependencyInjection;
using Shiny;

namespace MyApp
{
    public class MyAppStart : ShinyStartup
    {
        public override void ConfigureServices(IServiceCollection builder)
        {
            builder.UseGeofencing<GeofenceDelegate>(true);
            builder.UseNotifications(true);
        }
    }
}

using Shiny.Locations;
using Shiny.Notifications;
using System.Threading.Tasks;

namespace MyApp.Services.BackGroundJobs
{
    public class GeofenceDelegate : IGeofenceDelegate
    {
        readonly Inotificationmanager notifications;

        public GeofenceDelegate(Inotificationmanager notifications)
        {
            this.notifications = notifications;
        }

        public async Task OnStatusChanged(GeofenceState newStatus,GeofenceRegion region)
        {
            await this.notifications.Send(new Notification
            {
                Title = "Working",Message = "It is good to have you back " + region.Identifier
            });
            if (newStatus == GeofenceState.Entered)
            {
                await this.notifications.Send(new Notification
                {
                    Title = "WELCOME!",Message = "It is good to have you back " + region.Identifier
                });
            }
            else
            {
                await this.notifications.Send(new Notification
                {
                    Title = "GOODBYE!",Message = "You will be missed at " + region.Identifier
                });
            }
        }
    }
}

MainActivity.cs

 public override void OnRequestPermissionsResult(int requestCode,string[] permissions,Permission[] grantResults)
        {
            AndroidShinyHost.OnRequestPermissionsResult(requestCode,permissions,grantResults);
            PermissionsImplementation.Current.OnRequestPermissionsResult(requestCode,grantResults);
        }

MainApplication.cs

 public override void OnCreate()
        {
            base.OnCreate();
            RegisteractivityLifecycleCallbacks(this);

            AndroidShinyHost.Init(this,new MyAppStart(),services => {
                // register any platform specific stuff you need here
            });
            //A great place to initialize Xamarin.Insights and Dependency Services!
        }

private async void Checkgeofences()

            // shiny doesn't usually manage your viewmodels,so we'll do this for Now
             var geofences = ShinyHost.Resolve<IGeofenceManager>();
            var notifications = ShinyHost.Resolve<Inotificationmanager>();


            // this is really only required on iOS,but do it to be safe
            var access = await notifications.RequestAccess();

            {

                await geofences.StartMonitoring(new GeofenceRegion(
                    "CN Tower - Toronto,Canada",new Position(23.7430,21.2363),distance.FromMeters(3)
