The invention discloses an android system application closing method and an android system application closing device and mainly relates to the technical field of computers. The method comprises the following specific steps of monitoring whether an incubation process is started in an android system, if the incubation process is started, judging whether the process belongs to a process in a necessary range of the system, if the process does not belongs to the process in the necessary range of the system, recording process information of the process; judging whether a close instruction triggered by a user is received or not under a screen lock state of the android system; if the close instruction is received, closing the process according to the recorded process information. According to the method and the device, process information of an app can be recorded, after the screen of the system is locked, if the user triggers the close instruction through a function key of a terminal, the process can be closed according to the recorded process information, so that the method and the device have the beneficial effects that processes which are without the necessary range of the system and operate in the android system can be conveniently closed under the screen lock state and the power consumption of the system is reduced.
