Question

使用Xamarin表格-pcl v 2.3.4.267 -Plugin.FirebasePushNotification v 1.04-和prism MVVM库 - 在Android设备上调试。

我根据此文档https://github.com/CrossGeeks/FirebasePushNotificationPlugin/blob/master/README.md实施了FCM 并且我已成功向应用程序发送通知，我所坚持的是

如何在用户点击通知时打开特定页面，并根据通知类型打开所选页面，例如（当用户点击接受优惠的通知时，将打开优惠页面，当用户点击警报通知时，警报页面将被打开。）

我尝试在App.cs类中实现IPushNotificationHandler但是onopened方法永远不会被命中。

除非OnNotificationOpened打开通知，否则从未打过电话。

更新

在App.cs中我订阅了一个主题

     public App(Prism.DryIoc.IPlatformInitializer initializer = null) : base(initializer)
    {
        CrossFirebasePushNotification.Current.Subscribe("general");
        CrossFirebasePushNotification.Current.OnTokenRefresh += (s,p) =>
        {

            System.Diagnostics.Debug.WriteLine($"TOKEN : {p.Token}");
        };
        CrossFirebasePushNotification.Current.OnNotificationReceived += (s,p) =>
        {

            System.Diagnostics.Debug.WriteLine("Received");

        };


        CrossFirebasePushNotification.Current.OnNotificationOpened += (s, p) =>
        {

           // System.Diagnostics.Debug.WriteLine("Opened");
            foreach (var data in p.Data)
            {
                System.Diagnostics.Debug.WriteLine($"{data.Key} : {data.Value}");
            }

            if (!string.IsNullOrEmpty(p.Identifier))
            {
                System.Diagnostics.Debug.WriteLine($"ActionId: {p.Identifier}");
            }

        };

在mainapplication中，我添加了

     #if DEBUG
        FirebasePushNotificationManager.Initialize(this,
                      new NotificationUserCategory[]
                      {
                new NotificationUserCategory("message",new List<NotificationUserAction> {
                    new NotificationUserAction("Reply","Reply", NotificationActionType.Default),
                    new NotificationUserAction("Forward","Forward", NotificationActionType.Foreground)

                }),
                new NotificationUserCategory("request",new List<NotificationUserAction> {
                new NotificationUserAction("Accept","Accept", NotificationActionType.Default, "check"),
                new NotificationUserAction("Reject","Reject", NotificationActionType.Default, "cancel")
                })
                      }, true);
     #else
        FirebasePushNotificationManager.Initialize(this,
            new NotificationUserCategory[]
            {
                new NotificationUserCategory("message",new 
        List<NotificationUserAction> {
                    new NotificationUserAction("Reply","Reply", 
       NotificationActionType.Foreground),
                    new NotificationUserAction("Forward","Forward", 
        NotificationActionType.Foreground)

                }),
                new NotificationUserCategory("request",new List<NotificationUserAction> {
                new NotificationUserAction("Accept","Accept", NotificationActionType.Default, "check"),
                new NotificationUserAction("Reject","Reject", NotificationActionType.Default, "cancel")
                })
            }, false);
        #endif

然后我发送了数据信息，我收到了通知，并在打开通知后

     CrossFirebasePushNotification.Current.OnNotificationOpened

被击中但从未经过其代码块。
