Abstract

This application discloses a coordinated control method and system for electronic devices. When triggering coordinated control, a second electronic device sends remote view logic information associated with a running business to a first electronic device. The first device directly locally loads an application-related interface based on an interface layout file included in the remote view logic information. In this way, for the first device end, a component, a parameter, and the like that are related to the running application of the second device do not need to be customized on the first device end for the running application, and only the remote view logic information transmitted to the first device needs to be loaded. Distributed application logic may be defined for all running applications of the second device on a side of the second device, and then the second device synchronizes the distributed application logic with the first device.

First claim

What is claimed is:

1. A coordinated control method for electronic devices, wherein the electronic devices comprise a first electronic device used as a controlling party and a second electronic device used as a controlled party that are connected based on near field communication, the coordinated control method comprising:
running, by the second electronic device, an application and triggering coordinated control, and sending remote view logic information associated with the application to the first electronic device, wherein the remote view logic information comprises an interface layout file;
receiving, by the first electronic device, the remote view logic information, locally loading, based on the interface layout file, an interface related to the application, and binding a service that is on a side of the second electronic device and that is related to the application; and
sending, by the first electronic device, control information to the second electronic device based on a service interface externally disclosed by the service, so that the first electronic device controls the second electronic device to run the application;
wherein when running the application, the second electronic device triggers the coordinated control, and
when running the application and triggering the coordinated control, the second electronic device establishes a data physical channel between the second electronic device and the first electronic device based on distributed middleware to transmit the remote view logic information.

2. The coordinated control method according to claim 1 , wherein the interface layout file comprises an application control related to the application.

3. The coordinated control method according to claim 2 , wherein binding the service that is on the side of the second electronic device comprises:
loading, by the first electronic device, the interface layout file;
constructing, by the first electronic device, a view tree by loading the interface layout file; and
binding, by the first electronic device, the service related to the application while constructing the view tree.

4. The coordinated control method according to claim 2 , wherein the first electronic device locally loads the interface based on the interface layout file.

5. The coordinated control method according to claim 1 , wherein the control information is transferred by the service interface externally disclosed by the service that is on the side of the second electronic device.

6. The coordinated control method according to claim 5 , wherein the first electronic device registers with CallBack related to the second electronic device, the first electronic device transfers an ICallBack handle to the second electronic device through the service interface, and the second electronic device reversely controls the first electronic device by using the ICallBack handle.

7. The coordinated control method according to claim 1 , wherein the data physical channel comprises a socket channel.

8. The coordinated control method according to claim 7 , wherein before the data physical channel is established between the first electronic device and the second electronic device, the first electronic device performs device trusted authentication and key credential exchange on the first electronic device and the second electronic device by using the distributed middleware.

9. The coordinated control method according to claim 1 , wherein the distributed middleware separately provides a platform interface for the second electronic device and the first electronic device, to transfer the remote view logic information through the platform interface.

10. The coordinated control method according to claim 9 , wherein the second electronic device transfers the remote view logic information to the first electronic device through the platform interface in a binary digital stream.

11. The coordinated control method according to claim 10 , wherein the platform interface implements a cross-process based on a binder mechanism.

12. The coordinated control method according to claim 1 , wherein the coordinated control method further comprises:
unbinding, by the first electronic device based on the distributed middleware, the service that is bound on the side of the second electronic device.

13. The coordinated control method according to claim 1 , wherein when running the application, the second electronic device refreshes an interface on the side of the second electronic device based on the control information.

14. A coordinated control system for electronic devices comprising:
a first electronic device used as a controlled party;
a second electronic device used as a controlled party, wherein the first electronic device and the second electronic device are connected based on near field communication;
the second electronic device runs an application and triggers coordinated control, and sends remote view logic information associated with the application to the first electronic device, wherein the remote view logic information comprises an interface layout file;
the first electronic device receives the remote view logic information, locally loads an interface based on the layout file, and binds a service that is on a side of the second electronic device and that is related to the application; and
the first electronic device sends control information to the second electronic device based on a service interface externally disclosed by the service, so that the first electronic device locally controls the second electronic device to run the application;
wherein when running the application, the second electronic device triggers the coordinated control, and
when running the application and triggering the coordinated control, the second electronic device establishes a data physical channel between the second electronic device and the first electronic device based on distributed middleware to transmit the remote view logic information.

15. The coordinated control system according to claim 14 , wherein when running the application, the second electronic device refreshes an interface on a side of the first electronic device based on the control information.

16. The coordinated control system according to claim 14 , wherein the second electronic device triggers the coordinated control when running a specific application.

17. The coordinated control system according to claim 16 , wherein the data physical channel comprises a socket channel.

18. The coordinated control system according to claim 16 , wherein the distributed middleware separately provides a platform interface for the second electronic device and the first electronic device, to transfer the remote view logic information through the platform interface.
