BackGround Task to trigger if any changes in the Action Center

Question

I need to trigger my background task when the application added the toast notification to the action center. I have tried with ToastNotificationHistoryChangedTrigger and it's not triggering the task when the application added the toast notification. Is there any solution for it?

Answer 1

ToastNotificationHistoryChangedTrigger is fired whenever the collection of toast notification history from your app changes on the device. Subscribing this trigger, will allow your app to get notified when:

• A toast notification is removed by the user from action center;
• A toast notification is expired and removed by the system from action center;
• A toast notification is delivered form your app, via push;

Note: the only thing your app wouldn’t be notified for, is a local toast being popped/added, since it is not necessary to notify your app client about something it just did.

So generally, an app can be notified with ToastNotificationHistoryChangedTrigger when the app’s collection of notifications is changed in any way that’s not caused by the app’s local client. If your application added the toast notification by itself, the trigger won't be fired.
