在OnRegistered方法中将标签添加到NotificationHub [英] Adding a Tag to a NotificationHub in OnRegistered method

问题描述

在成功登录后的应用程序中，我想使用一个标签(其中Tag是电子邮件地址)注册到NotificationHub.

In my application after successfully login I would like to register to the NotificationHub with a Tag, where Tag is an email address.

以下情况在iOS上可以正常运行:

The following scenario works fine on iOS:

MessagingCenter.Subscribe<LoginViewModel, string>(this, MessagesId.RegisterForPush, (s, arg) =>
            {
                NSSet tags = new NSSet(arg); // create tags if you want
                Hub.RegisterNativeAsync(deviceToken, tags, (errorCallback) =>
                {
                    if (errorCallback != null)
                        Console.WriteLine("RegisterNativeAsync error: " + errorCallback.ToString());
                });
            });

但等同于Android的抛出NetworkOnMainThreadException:

but equivalent for Android throws an NetworkOnMainThreadException:

MessagingCenter.Subscribe<LoginViewModel, string>(this, MessagesId.RegisterForPush, (s, arg) =>
        {
            var tags = new List<string>() { arg };

            try
            {
                var hubRegistration = Hub.Register(registrationId, tags.ToArray());
            }
            catch (Exception ex)
            {
                Log.Error(PushHandlerBroadcastReceiver.TAG, ex.Message);
            }
        });

您知道如何解决此问题吗?

Do you have any idea how to solve this issue?

推荐答案

使用Task.Run进行主UI线程 off 的注册过程.

Use a Task.Run to get the registration process off the main UI thread.

await Task.Run(() =>
{
   // your register code here...
});
