Lockscreen slideshow from localStorage Folder?

Question

I'm trying to run a slideshow for the lockscreen with a xml file from the localFolder.

History

Apart from Microsofts official example being broken (the feed itself in the sample dosen't exist anymore) I was able to run a lockscreen slideshow with the example from David Catuhe

So I took the xml from the example, saved it locally and put it in the localFolder and inside my solutionfolder (to test both scenarios)

Problem

I created a Uri to the xml inside the localFolder like this:

public static StorageFolder localFolder = ApplicationData.Current.LocalFolder; 
public static StorageFile feedFile;

...

feedFile = await localFolder.GetFileAsync("images.xml");

if (Uri.TryCreate(feedFile.Path, UriKind.RelativeOrAbsolute, out dataUri))
{
   Debug.WriteLine("dataUri:" + dataUri);
}

...

SetImageFeedResult result = await LockScreen.RequestSetImageFeedAsync(dataUri);

But everytime I try to run the app, it says something about an error while configuring the slideshow for the lockscreen. The result itself just says "SetImageFeedResult.UserCanceled"

This is also true if I try to create the uri from inside the app-package with "ms-appx:///" or "ms-appdata:///"

Any idea why this won't work?

Also as a sidenote: The behaviour from windows seems a bit random when adding an online rss image feed. I have to activate the lockscreen several times before it shows finally (that goes only for the online rss from David Catuhe's example, not the above explained local problem).

Answer 1

How to do this?

Answer 2

Hi,

The new LockScreen.RequestSetImageFeedAsync method that is available in Windows 8.1 allows to set a remote RSS feed as source for the Lock Screen slideshow.The Url should be an external URL .

Best Wishes!

Thanks... David Cathue also confirmed that on his blog. 

That' a pitty... think of what you & the user could do with usergenerated content from an app and the lockScreen - would be a nice feature to have.
