After hours of debugging i found the exception type, but Need help to solve my problem. As i wrote above, i followed the instructions from MSDN on how to create and update secondary live tiles. Now i update them with the following code
Code:
TileUpdateManager.CreateTileUpdaterForSecondaryTile(item.Id.ToString()).Update(tileNotification);
This works fine, until i update my app, then on this line of code it throws the following exception
Code:
$exception {System.Exception: The application identifier provided is invalid.
at Windows.UI.Notifications.TileUpdateManager.CreateTileUpdaterForSecondaryTile(String tileId)
I found other users have this issue, some of them says, that this is a bug of wp8.1 update 1. The only way i think to solve this, is to unpin and repin the live tiles, but this is not an Option for me, because when users do update the app, but dont open it, they think the app is broken, bracuase the live tiles doesnt update anymore.
What can i do now?
