Problems solved by technology

[0003] However, with the existing technology, it is necessary to manually close the temporarily unused background program, and after manually closing the program, it will still be automatically started, resulting in high power consumption
If you end this program directly, it will take a long time to start this program again

Embodiment 1

[0024] The embodiment of the present invention provides a kind of energy-saving method of Android system, such as figure 1 As shown, the method includes the following steps:

[0025] Step 101, after receiving an instruction to suspend the currently running program, save the current relevant information of the program, and stop running the relevant process of the program;

[0026] The instruction is a preset gesture or preset instruction input by the user before the method is executed.

[0027] A main control service program for performing the suspending and unsuspending operations is preset, and the main control service program is automatically started when the Android system is started.

[0028] The relevant information includes data currently processed by the program and current state information;

[0029] The related process refers to a process of the same level related to the current program and a child process of the current program.

[0030] Step 102, releasing the ha...

Abstract

The invention discloses an energy saving method and an energy saving device for an Android system, and relates to the technical field of electronics. By the energy saving method and the energy saving device, power consumption of a mobile terminal can be reduced, and elapsed time is shortened when a program is restarted. The method in an embodiment of the invention includes storing current relevant information of the program when an instruction that the currently running program needs to be suspended is received, and stopping running relevant processes of the program; releasing hardware resources occupied by the program; running the relevant processes of the suspended program again after an instruction of resuming the suspended program is received, and restoring the stored relevant information of the suspended program; and distributing the hardware resources required by the suspended program. According to the scheme of the embodiment of the invention, the energy saving method and the energy saving device have the advantage that the energy saving method and the energy saving device are applicable to saving energy for the mobile terminal in the Android system.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to an energy-saving method and device for an Android system. Background technique [0002] The Android system is a Linux-based open source operating system, mainly used for portable devices. Android is currently one of the most popular mobile terminal platforms in the world, and its multi-functional open design enables the mobile terminal to undertake tasks close to that of a PC (personal computer, personal computer). However, the Android system is relatively weak in terms of battery life, that is, the power consumption is large, so that the battery life of the mobile terminal is relatively short. In order to reduce the power consumption of the Android system, usually end users use the Android system's built-in task manager or third-party software to manually end some background programs that are not in use temporarily, so as to release hardware resources and reduce the CPU (Ce...
