System, method for cleaning memory space and terminal device with memory space cleaning function

摘要

A method for cleaning memory space includes marking an application of a terminal device when that application is launched in response to a launching operation, loading each marked application to an application resource pool of the terminal device, counting a total number of marked times of each application in the application resource pool, determining if the total number of marked times of each application in the application resource pool is greater than or equal to a predetermined number of times, determining the applications, which have a total number of marked times greater than or equal to the predetermined number of times, in the application resource pool, as non-removable applications and determining other applications of the terminal device as removable applications, and cleaning the memory space occupied by the removable applications when available memory space of the terminal device is not enough.
