Dynamic types for activity continuation between electronic devices

A source electronic device comprising:

• a processor;
• and
• a computer readable storage medium comprising instructions that, when executed by the processor, cause the source electronic device to perform operations comprising:
• receiving activity information from a first application of the source electronic device describing an activity performed in the first application;
• determining dynamic type information describing an attribute of the activity performed in the first application corresponding to the activity information, the dynamic type information including a dynamic type identifier for the activity;
• sending an activity advertisement message to a companion electronic device, the activity advertisement message comprising the dynamic type information;
• in response to sending the activity advertisement message, receiving a request for extended activity data for the activity from the companion electronic device, wherein the companion electronic device includes a second application configured to perform a corresponding activity to the activity performed in the first application on the source electronic device;
• and
• sending the extended activity data to the companion electronic device, the extended activity data being used to configure the second application on the companion electronic device to continue the activity.

A non-transitory computer-readable medium including one or more sequences of instructions that, when executed by one or more processors of a source electronic device, causes:

• receiving activity information from a first application of the source electronic device describing an activity performed in the first application;
• determining dynamic type information describing an attribute of the activity performed in the first application corresponding to the activity information, the dynamic type information including a dynamic type identifier for the activity;
• sending an activity advertisement message to a companion electronic device, the activity advertisement message comprising the dynamic type information;
• in response to sending the activity advertisement message, receiving a request for extended activity data for the activity from the companion electronic device, wherein the companion electronic device includes a second application configured to perform a corresponding activity to the activity performed in the first application on the source electronic device;
• and
• sending the extended activity data to the companion electronic device, the extended activity data being used to configure the second application on the companion electronic device to continue the activity.
