Question

当我的应用关闭时，我会收到来自FCM的新通知，但是当我点按它时，我的应用会崩溃。当我的应用程序处于后台或前台时，它是可以的，然后他们将打开通知的右页。我不打电话给SendNotification，因为我不想在应用程序处于前台时收到本地通知。

我的fcm服务：

protected override void OnCreate(Bundle bundle)
    {


        TabLayoutResource = Resource.Layout.Tabbar;
        ToolbarResource = Resource.Layout.Toolbar;

        base.OnCreate(bundle);
        Forms.Init(this, bundle);
        ImageCircleRenderer.Init();

        IsPlayServicesAvailable();

        if (Intent.Extras != null)
        {
            NotificationSendObject notifcation = new NotificationSendObject();
            foreach (var key in Intent.Extras.KeySet())
            {
                switch (key)
                {
                    case "object_id":
                        notifcation.objectId = Intent.Extras.GetString(key);
                        break;
                    case "notification_id":
                        notifcation.notificationId = Intent.Extras.GetString(key);
                        break;
                    case "object_type":
                        notifcation.objectType = Intent.Extras.GetString(key);
                        break;
                }
            }
            if (notifcation.notificationId != null)
            {
                MessagingCenter.Send(App.CurrentApp, "OnTapNotification", notifcation);
            }
        }


        SecureStorageImplementation.StoragePassword = "*****";

        LoadApplication(new App());

    }

OnCreate中的通知处理：

<phase>prepare-package</phase>

我找到了一个解决方案，必须在LoadApplication方法之后调用Intent.Extras。

修正：

protected override void OnCreate(Bundle bundle)
{


    TabLayoutResource = Resource.Layout.Tabbar;
    ToolbarResource = Resource.Layout.Toolbar;

    base.OnCreate(bundle);
    Forms.Init(this, bundle);
    ImageCircleRenderer.Init();

    IsPlayServicesAvailable();

    SecureStorageImplementation.StoragePassword = "*****";

    LoadApplication(new App());

    if (Intent.Extras != null)
    {
        NotificationSendObject notifcation = new NotificationSendObject();
        foreach (var key in Intent.Extras.KeySet())
        {
            switch (key)
            {
                case "object_id":
                    notifcation.objectId = Intent.Extras.GetString(key);
                    break;
                case "notification_id":
                    notifcation.notificationId = Intent.Extras.GetString(key);
                    break;
                case "object_type":
                    notifcation.objectType = Intent.Extras.GetString(key);
                    break;
            }
        }
        if (notifcation.notificationId != null)
        {
            MessagingCenter.Send(App.CurrentApp, "OnTapNotification", notifcation);
        }
    }

}

使用FCM关闭应用程序时如何处理通知？
