Multi-application state navigation

One or more computer storage media having computer-executable instructions embodied thereon, which, when executed by a computing device, cause the computing device to perform a method of communicating event records from a first secondary application to a second secondary application, the method comprising:

• generating an event record for the first secondary application, the event record comprising:
• an unencrypted textual hint that describes a first application experience generated by the first secondary application at a point in time;
• and
• encrypted state information that is usable by the first secondary application to recreate the first application experience;
• communicating the event record to the second secondary application, wherein the second secondary application does not have access to a decryption key that allows the encrypted state information to be decrypted;
• changing the second secondary application to a second application experience that is different from the first application experience;
• receiving the encrypted state information from the first secondary application;
• and
• using the encrypted state information to change the second application experience of the second secondary application to the first application experience.

A system for state-enabled navigation between applications, the system comprising:

• one or more processors;
• and
• computer memory storing computer-usable instructions that perform operations when the instructions are executed by the one or more processors, the operations comprising:
• receive, at a first secondary application, an event record from a second secondary application, wherein the event record describes an application experience generated by the second secondary application at a point in time, wherein the event record further comprises:
• encrypted state information that is usable by the second secondary application to recreate the application experience;
• and
• an unencrypted textual hint that describes the application experience;
• store the event record;
• receive a user input through the first secondary application;
• determine that the user input is related to the event record;
• output a contextual suggestion generated using information in the event record, wherein the contextual suggestion includes an interface control that launches the first secondary application to the application experience when selected;
• receive a selection of the interface control;
• and
• based on the selection, communicate the encrypted state information to the first secondary application.
