Cross device application discovery and control
Systems and methods cross device application discovery and/or control. Cross device application discovery and/or control can provide for simple detection and activation of applications on remote devices. Cross device application discovery and/or control can provide for the control of remote applications in a master and slave configuration. Responsive to an activation message, an application can execute a task in an application, the task being displayed on a target device. Responsive to an activation message, an application can execute a task in an application on a target device, a task context data for the task being streamed to the source device for presentation on a display. Cross device application discovery and/or control can be enabled on a single operating system, or across a plurality of operating systems.
1. A computer-implemented method for application discovery, the method comprising:
receiving, at a target device, an application discovery query from a source device;

determining, on the target device, based on a device capability of the target device, that the target device is capable of executing a task;
determining, on the target device, based on an application capability of the target device, that the target device has an application capable of executing the task; and
sending, from the target device, in response to the receiving of the application discovery query, a discovery response message to the source device, the discovery response message being based on determining that the target device is capable of executing the task and has an application capable of executing the task.

sending, from the target device, an application response message to the source device, wherein the application response message comprises at least one of:
a notification of the task associated with the application running on the target device; and
the task context data for presentation by the source device.

determining based on a device capability of the target device, that the target device is capable of executing a task;
determining based on an application capability of the target device, that the target device has an application capable of executing the task; and
in response to the receiving of the application discovery query, sending a discovery response message to the source device, the discovery response message being based on determining that the target device is capable of executing the task and has an application capable of executing the task.
9. The target device of claim 8 , wherein the operations further comprise:
receiving an application activation message; and
responsive to receiving the application activation message, activating the application on the target device.
10. The target device of claim 9 , wherein the operations further comprise:

the task context data for presentation by the source device.
11. The target device of claim 9 , wherein the operations further comprise:
running a task of the application, wherein the task has associated task context data; and
sending an application response message to the source device, wherein the application response message is comprised at least of:
a notification of the task running on the application on the target device; and
a notification of the task context data being presented by the target device.
12. The target device of claim 8 , wherein the operations further comprise:
receiving a background task activation message from the source device;
responsive to the receiving the background task activation message, activating a background task on the target device; and
sending, from the target device, a background task response message to the source device.
13. The target device of claim 8 , wherein the application capability indicates performance data of the application.
14. The target device of claim 8 , wherein the device capability indicates at least one of device memory capability, device speed capability, and device display capability.
15. A source device comprising:
at least one processor; and
memory storing instructions that, when executed by the at least one processor, cause the source device to perform operations comprising:
