I'm having problems to get my Windows Phone 8.1 live tile update by itself daily (around 7am)
My project has 2 parts :
- a Web API project hosted on Azure that provides the tile template in XML (that part works fine)
- a Windows Phone 8.1 project with a single MainPage.xaml where I build 2 square/wide tiles
When I pin my app to the start screen from the app list, my tile (whether I choose the square or wide format) flips back and forth between my 2 brands of the day just fine. The next morning at 7:15 am, the tile won't update with the 2 new brands :(
I noticed that if I tap the tile to launch the app and come back to the start screen, the tile has updated. It also works if I unpin and repin the tile but in both cases, that's "cheating" :-/
I call my Azure website like this to get the tile templates of both brands : http://example.azurewebsites.net/api/tiles/0 (BRAND1)
http://example.azurewebsites.net/api/tiles/1 (BRAND2)
The XML tile template looks like this (example):
<tile>
<visual>
<binding template="TileWide310x150ImageAndText01">
<image id="1" src="http://www.example.com/sales/BRAND1/visualWide.png"/>
<text id="1">Brand 1</text>
</binding>
<binding template="TileSquare150x150PeekImageAndText04">
<image id="1" src="http://www.example.com/sales/BRAND1/visualSquare.png"/>
<text id="1">Brand 1</text>
</binding>
</visual>
</tile>
The WP8.1 page contains this :
public MainPage()
{
this.InitializeComponent();
this.NavigationCacheMode = NavigationCacheMode.Required;
TileUpdateManager.CreateTileUpdaterForApplication().EnableNotificationQueue(true);
PeriodicUpdateRecurrence recurrence = PeriodicUpdateRecurrence.Daily;
Task<string> responseBody;
for (int i = 0; i < 2; i++)
{
using (var httpClient = new HttpClient())
{
httpClient.BaseAddress = new Uri("http://xxxxx.azurewebsites.net/api/tiles/" + i); //I hid the address here for discretion
HttpResponseMessage response = httpClient.GetAsync(httpClient.BaseAddress).Result;
string statusCode = response.StatusCode.ToString();
response.EnsureSuccessStatusCode();
responseBody = response.Content.ReadAsStringAsync();
}
XmlDocument xmlDoc = new XmlDocument();
xmlDoc.LoadXml(responseBody.Result);
string srcWide, srcSquare, textWide, textSquare, templateWide, templateSquare;
XElement root = XElement.Parse(responseBody.Result);
IEnumerable<XElement> wideElement = root.Descendants("binding").Where(a => a.Attribute("template").Value.ToLower().Contains("wide"));
IEnumerable<XElement> squareElement = root.Descendants("binding").Where(a => a.Attribute("template").Value.ToLower().Contains("square"));
templateWide = wideElement.Attributes("template").SingleOrDefault().Value;
srcWide = wideElement.Descendants("image").Attributes("src").SingleOrDefault().Value;
textWide = wideElement.Descendants("text").SingleOrDefault().Value;
templateSquare = squareElement.Attributes("template").SingleOrDefault().Value;
srcSquare = wideElement.Descendants("image").Attributes("src").SingleOrDefault().Value;
textSquare = wideElement.Descendants("text").SingleOrDefault().Value;
XmlDocument wideTileXml = TileUpdateManager.GetTemplateContent(TileTemplateType.TileWide310x150ImageAndText01);
XmlNodeList wideTileTextAttributes = wideTileXml.GetElementsByTagName("text");
wideTileTextAttributes[0].InnerText = textWide;
XmlNodeList wideTileImageAttributes = wideTileXml.GetElementsByTagName("image");
((XmlElement)wideTileImageAttributes[0]).SetAttribute("src", srcWide);
((XmlElement)wideTileImageAttributes[0]).SetAttribute("alt", textWide);
XmlDocument squareTileXml = TileUpdateManager.GetTemplateContent(TileTemplateType.TileSquare150x150PeekImageAndText01);
XmlNodeList squareTileTextAttributes = squareTileXml.GetElementsByTagName("text");
squareTileTextAttributes[0].AppendChild(squareTileXml.CreateTextNode(textSquare));
XmlNodeList squareTileImageAttributes = squareTileXml.GetElementsByTagName("image");
((XmlElement)squareTileImageAttributes[0]).SetAttribute("src", srcSquare);
((XmlElement)squareTileImageAttributes[0]).SetAttribute("alt", textSquare);
IXmlNode node = wideTileXml.ImportNode(squareTileXml.GetElementsByTagName("binding").Item(0), true);
wideTileXml.GetElementsByTagName("visual").Item(0).AppendChild(node);
TileNotification tileNotification = new TileNotification(wideTileXml);
tileNotification.ExpirationTime = DateTimeOffset.UtcNow.AddDays(1).AddHours(7).AddMinutes(0);
TileUpdateManager.CreateTileUpdaterForApplication().Update(tileNotification);
}
List<Uri> urisToPoll = new List<Uri>(5);
urisToPoll.Add(new Uri("http://example.azurewebsites.net/api/tiles/0")); //fake url
urisToPoll.Add(new Uri("http://example.azurewebsites.net/api/tiles/1")); //fake url
//I want the tile to update its content every day at 7:15am
//(the Azure website supposedly returns new brands of the day at 7am)
DateTime dtTomorrow7 = DateTime.SpecifyKind(DateTime.Today.AddDays(1).AddHours(7).AddMinutes(15), DateTimeKind.Local);
DateTimeOffset dtoTomorrow7 = dtTomorrow7;
TileUpdateManager.CreateTileUpdaterForApplication().StartPeriodicUpdateBatch(urisToPoll, dtoTomorrow7, recurrence);
}
I'm not sure I'm using the StartPeriodicUpdateBatch method correctly. In debug mode,I can see the DateTimeOffset value is Day+1 7:15am +2:00 which looks correct but the tile does not update. I live in France that is UTC+2 Thanks for your suggestions.
