MozActivityRequestHandler

This API is available on Firefox or Firefox OS for installed or higher privileged applications.

Summary

The MozActivityRequestHandler interface allows apps that handle activities to access and interact with the request made by a third party app that tries to delegate an activity.

To handle activities, an application has to register a handler to the system message activity using navigator.mozSetMessageHandler(). The callback that is passed to navigator.mozSetMessageHandler() will be called with a MozActivityHandler object in parameter when the system message is of the type activity.

Be aware that you need to have returnValue: true set in your manifest file to return a result (see manifest activities for more information.) If there is no result to return, then you should just use window.close() to get rid of the handling window.
