Electronic device and method for sharing screen

1. An electronic device comprising:

a memory;

a display;

a communication circuit; and

at least one processor electrically connected to the memory and configured to:

execute a first application;

control the display to display a first screen related to the first application;

display a first object having a first shape on the first screen;

control the communication circuit to transmit data to an external electronic device for displaying the first screen on the external electronic device;

receive a first input for the displayed first object; and

based on switching the first application from a foreground state to a background state in response to receiving the first input, control the display to display a second screen while controlling the communication circuit to maintain transmission of the data to the external electronic device for displaying the first screen and display a second object having a second shape changed from the first shape,

wherein the second object having the second shape includes an image related to the first application.

2. The electronic device of claim 1 , wherein the at least one processor is further configured to:

control the display to display a plurality of items for functions executable through the first object in response to receiving a second input for the first object, the plurality of items including at least one of an item representing a function for switching the first application executed in the background state to the foreground state, an item representing a function for stopping transmission of the data, an item representing a function for changing a device connected to the electronic device to another external electronic device, an item for controlling the first application executed in the background state, or an item representing a function for terminating a connection with the external electronic device.

3. The electronic device of claim 1 , wherein, based on the first screen being associated with reproduction of content, the second object having the second shape includes an element indicating a time point associated with the content reproduction.

4. The electronic device of claim 1 , wherein the second object having the second shape includes a contour having a color indicating the first application.

5. The electronic device of claim 1 , wherein the first object having the first shape is generated based on the at least one processor controlling the communication circuit to establish a connection with the external electronic device.

6. The electronic device of claim 1 , wherein the at least one processor is further configured to control the display to display a window for displaying the first screen being displayed on the external electronic device, in response to receiving a second input for the second object having the second shape, the window overlapping the second screen.

7. The electronic device of claim 6 , wherein the at least one processor is further configured to change a size of the window in response to receiving a third input in the window and change a location of the window in response to receiving a fourth input in the window.

8. A method for an electronic device, the method comprising:

displaying, on a display of the electronic device, a first screen related to a first application;

displaying a first object having a first shape on the first screen;

transmitting data to an external electronic device for displaying the first screen on the external electronic device;

receiving a first input for the displayed first object;

based on switching the first application from a foreground state to a background state in response to receiving the first input, displaying on the display a second screen while maintaining transmission of the data to the external electronic device for displaying the first screen, and displaying a second object having a second shape changed from the first shape,

wherein the second object having the second shape includes an image related to the first application.

9. The method of claim 8 , further comprising:

displaying a plurality of items for functions executable through the first object in response to receiving a second input for the first object, wherein the plurality of items includes at least one of an item representing a function for switching the first application executed in the background state to the foreground state, an item representing a function for stopping transmission of the data, an item representing a function for changing a device connected to the electronic device to another external electronic device, an item for controlling the first application executed in the background state, or an item representing a function for terminating a connection with the external electronic device.

10. The method of claim 8 , wherein, based on the first screen being associated with reproduction of content, the second object having the second shape includes an element indicating a time point associated with the content reproduction.

11. The method of claim 8 , wherein the second object having the second shape comprises a contour having a color indicating the first application.

12. The method of claim 8 , wherein the first object having the first shape is generated based on establishing a connection with the external electronic device.

13. The method of claim 8 , further comprising displaying a window displaying the first screen being displayed on the external electronic device in response to receiving a second input for the second object having the second shape,

wherein the window overlaps the second screen.

14. An electronic device comprising:

a memory;

a display;

a communication circuit; and

at least one processor electrically connected to the memory and configured to:

indicate that a first screen related to a first application executed in a background state is being displayed on an external electronic device connected to the electronic device based on data transmitted from the electronic device; and

display an object including an image relating to the first application on a second screen being displayed on the electronic device.
