An application display method implemented by an electronic device comprising an ANDROID operating system, wherein the application display method comprises: detecting a first operation for starting a first application, wherein the electronic device comprises a first application and a display screen; displaying, in a landscape orientation state of the electronic device, a first interface of the first application in the display screen in response to the first operation, wherein the first interface corresponds to a first activity, the display screen comprises at least two areas, the at least two areas comprise a first area and a second area, and different areas do not overlap; detecting a second operation performed on the first interface, wherein the second operation is used to open a second interface of the first application, wherein the second interface corresponds to a second activity different from the first activity; displaying the second interface in the second area in response to the second operation, wherein the first interface is displayed in the first area while the second interface is displayed in the second area in response to the second operation; detecting a third operation performed on the second interface, wherein the third operation is used to open a third interface of the first application, the third interface corresponds to a third activity; if the third activity and the second activity are the same, updating, in response to the third operation, the second interface in the second area to the third interface and still displaying the first interface in the first area; if the third activity is different from the second activity, displaying the third interface in the second area in response to the third operation, and updating the first interface in the first area to the second interface in response to the third operation; wherein a level of the third interface is lower than a level of the second interface when the third activity is different from the second activity. detecting a first operation for starting a first application, wherein the electronic device comprises a first application and a display screen; displaying, in a landscape orientation state of the electronic device, a first interface of the first application in the display screen in response to the first operation, wherein the first interface corresponds to a first activity, the display screen comprises at least two areas, the at least two areas comprise a first area and a second area, and different areas do not overlap; detecting a second operation performed on the first interface, wherein the second operation is used to open a second interface of the first application, wherein the second interface corresponds to a second activity different from the first activity; displaying the second interface in the second area in response to the second operation, wherein the first interface is displayed in the first area while the second interface is displayed in the second area in response to the second operation; detecting a third operation performed on the second interface, wherein the third operation is used to open a third interface of the first application, the third interface corresponds to a third activity; if the third activity and the second activity are the same, updating, in response to the third operation, the second interface in the second area to the third interface and still displaying the first interface in the first area; if the third activity is different from the second activity, displaying the third interface in the second area in response to the third operation, and updating the first interface in the first area to the second interface in response to the third operation; wherein a level of the third interface is lower than a level of the second interface when the third activity is different from the second activity.
