windows-phone-7 - 无法从 Windows Phone 设备获取 pushchannel uri

Question

任何Windows Phone开发人员可以帮助我吗？我正在开发一个 Windows Phone 应用程序。当我尝试获取推送通道 uri 时，它适用于模拟器以及设备，但突然我今天遇到了问题。我使用的是相同的代码，但它对于模拟器和pushchannel_uri更新的事件触发工作正常，但是当我尝试从 Windows 手机获取推送通道 uri 时，它没有得到 uri，并且pushchannel_uri更新的事件根本没有触发。

我正在使用Nokia Lumia 510并且我已在应用程序中心注册为开发人员。

我的代码是

public class Cloud2Device
{
    ICloud2DeviceListener eventListener;
    Popup popup=new Popup();

    public Cloud2Device(ICloud2DeviceListener listener)
    {

        Loading loading=new Loading();
        popup.Child = loading;
        popup.IsOpen = true;


        eventListener = listener;
        /// Holds the push channel that is created or found.
        HttpNotificationChannel pushChannel = HttpNotificationChannel.Find(Constants.NOTIFICATION_CHANNEL_NAME);

        // If the channel was not found, then create a new connection to the push service.
        if (pushChannel == null)
        {
            pushChannel = new HttpNotificationChannel(Constants.NOTIFICATION_CHANNEL_NAME);
            // Register for all the events before attempting to open the channel.
            pushChannel.ChannelUriUpdated += new EventHandler<NotificationChannelUriEventArgs>(PushChannel_ChannelUriUpdated);
            pushChannel.ErrorOccurred += new EventHandler<NotificationChannelErrorEventArgs>(PushChannel_ErrorOccurred);

            // Register for this notification only if you need to receive the notifications while your application is running.
            pushChannel.ShellToastNotificationReceived += new EventHandler<NotificationEventArgs>(PushChannel_ShellToastNotificationReceived);

            pushChannel.HttpNotificationReceived += new EventHandler<HttpNotificationEventArgs>(PushChannel_HttpNotificationReceived); // Ra

            pushChannel.Open();

            // Bind this new channel for toast events.
            pushChannel.BindToShellToast();
        }
        else
        {
            // The channel was already open, so just register for all the events.
            pushChannel.ChannelUriUpdated += new EventHandler<NotificationChannelUriEventArgs>(PushChannel_ChannelUriUpdated);
            pushChannel.ErrorOccurred += new EventHandler<NotificationChannelErrorEventArgs>(PushChannel_ErrorOccurred);

            // Register for this notification only if you need to receive the notifications while your application is running.
            pushChannel.HttpNotificationReceived += new EventHandler<HttpNotificationEventArgs>(PushChannel_HttpNotificationReceived); // Ra

            pushChannel.ShellToastNotificationReceived += new EventHandler<NotificationEventArgs>(PushChannel_ShellToastNotificationReceived);


            // Thread.Sleep(5000);
            // Display the URI for testing purposes. Normally, the URI would be passed back to your web service at this point.
            System.Diagnostics.Debug.WriteLine(pushChannel.ChannelUri.ToString());
            // MessageBox.Show(String.Format("Channel Uri is {0}",pushChannel.ChannelUri.ToString()));
            string Id = pushChannel.ChannelUri.ToString();
            saveCloudDeviceID(Id);
        }
    }

    public void PushChannel_ChannelUriUpdated(object sender, NotificationChannelUriEventArgs e)

        // Parse out the information that was part of the message.

            if (string.Compare(
                key,
                "wp:Param",
                System.Globalization.CultureInfo.InvariantCulture,
                System.Globalization.CompareOptions.IgnoreCase) == 0)
            {
                relativeUri = e.Collection [ key ];
            }
        }

        // Display a dialog of all the fields in the toast.
