Projection method, electronic device, and system

A projection method, comprising:

• sending, by a second electronic device, a display request to a first electronic device, wherein the display request is a request sent by the second electronic device in response to a user operation performed on a projection window;
• receiving, by the second electronic device, first projection data sent by the first electronic device, wherein the first projection data is projection data corresponding to a first application running mode in one or multiple application running modes supported by a first application, the first application is determined by the first electronic device in response to the display request, and the one or multiple application running modes correspond to one or more electronic device types;
• displaying, by the second electronic device, the first application in the projection window in the first application running mode based on the first projection data;
• receiving, by the second electronic device, second projection data sent by the first electronic device, wherein the second projection data is projection data that is determined by the first electronic device based on a second application running mode corresponding to a device type of the first electronic device in response to a user operation of starting the first application on the first electronic device;
• and
• displaying, by the second electronic device, the first application in the projection window in the second application running mode based on the second projection data.

An electronic device, comprising a processor and a non-transitory memory, wherein the non-transitory memory is coupled to the processor and is configured to store a computer program code for execution by the processor, the computer program code comprises computer instructions for:

• determining a first application in response to a display request sent by a second electronic device;
• sending first projection data of the first application to the second electronic device based on a first application running mode in one or multiple application running modes supported by the first application, wherein the one or multiple application running modes correspond to one or more electronic device types, and the first projection data is used to cause the second electronic device to display the first application in the first application running mode;
• in response to a user operation of starting the first application on the electronic device, sending second projection data of the first application to the second electronic device based on a second application running mode corresponding to a device type of the electronic device, wherein the second projection data is used to cause the second electronic device to display the first application in the second application running mode;
• and
• displaying the first application in the second application running mode.
