Abstract: An application keepalive method includes, when a foreground application run by the electronic device is switched from a first application to a second application, a callback probability of the second application relative to the first application is obtained, and when the callback probability of the second application relative to the first application is greater than a preset threshold, a keepalive priority of the first application is increased when the first application is used as a background application. When system resources are insufficient, the electronic device ends a process of at least one background application in ascending order of keepalive priorities to release system resources.
