Application keep-alive method and electronic device

An electronic device, comprising a processor, wherein the processor is coupled to a memory, the memory stores program instructions, and when the program instructions stored in the memory are executed by the processor, the electronic device is enabled to:

• automatically perform a first locking operation on a first application running in the background, to add an application lock of a first type to the first application, wherein the application lock of the first type is an application lock actively added by the electronic device, the first application is an application that the electronic device predicts that a user will continue to use, and the first locking operation enables the first application to be in a keep-alive state;
• in response to a first operation of the user, display a multi-task interface, wherein the multi-task interface comprises preview interfaces of a plurality of recently used applications, the plurality of recently used applications comprises the first application and a second application, the preview interfaces of the plurality of applications comprise a first preview interface and a second preview interface, the first preview interface is a preview interface of the first application, and the second preview interface is a preview interface of the second application;
• display a first identifier on the first preview interface of the multi-task interface, wherein the first identifier indicates that the application lock of the first type is added to the first application;
• and
• in response to a second operation performed by the user on the second preview interface, perform a second locking operation on the second application to add an application lock of a second type to the second application, and displaying a second identifier on the second preview interface, wherein the second identifier indicates that the application lock of the second type is added to the second application, the second locking operation enables the second application to be in a keep-alive state, and the application lock of the second type is an application lock added by the electronic device in response to a user operation.

A non-transitory computer-readable storage medium, comprising computer instructions, wherein when the computer instructions are run on an electronic device, the electronic device is enabled to:

• automatically perform a first locking operation on a first application running in the background, to add an application lock of a first type to the first application, wherein the application lock of the first type is an application lock actively added by the electronic device, the first application is an application that the electronic device predicts that a user will continue to use, and the first locking operation enables the first application to be in a keep-alive state;
• in response to a first operation of the user, display a multi-task interface, wherein the multi-task interface comprises preview interfaces of a plurality of recently used applications, the plurality of recently used applications comprises the first application and a second application, the preview interfaces of the plurality of applications comprise a first preview interface and a second preview interface, the first preview interface is a preview interface of the first application, and the second preview interface is a preview interface of the second application;
• display a first identifier on the first preview interface of the multi-task interface, wherein the first identifier indicates that the application lock of the first type is added to the first application;
• and
• in response to a second operation performed by the user on the second preview interface, perform a second locking operation on the second application to add an application lock of a second type to the second application, and displaying a second identifier on the second preview interface, wherein the second identifier indicates that the application lock of the second type is added to the second application, the second locking operation enables the second application to be in a keep-alive state, and the application lock of the second type is an application lock added by the electronic device in response to a user operation.
