从后台任务WP8.1更新LiveTile

问题描述

我无法从后台任务"更新手动固定的图块.

I cannot update manually pinned tile from Background Task.

var updater = TileUpdateManager.CreateTileUpdaterForApplication();
updater.EnableNotificationQueue(true);
updater.Clear();

XmlDocument tileXml = TileUpdateManager.GetTemplateContent(TileTemplateType.TileWideText03);

var title = "Test text";
string titleText = title == null ? String.Empty : title;
tileXml.GetElementsByTagName("text")[0].InnerText = titleText;

updater.Update(new TileNotification(tileXml));

CreateTileUpdaterForApplication()上引发异常；并显示消息:提供的应用程序标识符无效.

Exception fires on CreateTileUpdaterForApplication(); with message: The application identifier provided is invalid.

我听说Windows Phone 8.1更新会出现此问题，但是我没有找到任何解决方案...请帮助.

I heard what this problem occurs on Windows Phone with 8.1 update, but I not found any solutions... Please help.

I was having exactly the same issue. After three hours of research (damn waste of time :/) I found the solution:

var updater = TileUpdateManager.CreateTileUpdaterForApplication("App");
