RESUMPTION OF ACTIVITIES USING ACTIVITY DATA COLLECTED BY AN OPERATING SYSTEM

摘要

Technologies are described for resuming activities using activity data collected by an operating system. An operating system provides an application programming interface (“API”) through which applications can submit activity data. The activity data identifies an application and an activity previously performed using the application. The activity data can be presented to users in a UI that includes UI controls corresponding to the reported activities. The UI controls can identify the activity and the application used to perform the activity. The UI controls can be presented in an order determined based upon the time at which the corresponding activity was performed. The UI controls can be selected to resume the corresponding activity. Functionality can also be provided for scrolling through the UI controls, searching the activity data, filtering the represented activities, deleting the activity data corresponding to an activity, and performing other functions.
