Remarks

The UserActivity APIs allow an application to provide rich information for Cortana Pick-up Where I Left Off and the Timeline. A better re-engagement UI can be built within the consuming application if the source application can provide more details about the re-engagement. This method creates a collection of UserActivity objects from information stored in a JSON string that a source application provided so that the consuming application can get information about the source application, and the specific activities within the source application.
