Terminal and application program protection method

Abstract

The invention provides a terminal and an application program protection method. The terminal comprises an application program selection unit and a process priority adjusting unit, wherein the application program selection unit selects an application program required to be protected; and process priority adjusting unit adjusts a process priority of the application program required to be protected to be in a specific grade. According to the terminal and the application program protection method, the process priority of the application program can be upgraded to the specific grade according to the importance degree of the application program, so that a system cannot ends the application program preferentially when the quantities of processes are large or a memory is insufficient.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a terminal and an application program protection method. Background technique [0002] In the existing terminal system, the process priority is usually used to manage the application process: the system sets the priority of each process, and when the memory is insufficient, the system will select the process with the lowest priority and end it. [0003] Because the program runs for a long time, its process priority will become lower and lower. When the mobile phone memory is insufficient or the number of running programs exceeds the number set by the system, the system will select a process with a lower priority and end it. In order to protect the normal operation of the program and avoid being automatically terminated by the system, the existing solutions generally set the program as a resident program. A resident program refers to a program with the persistent attribute set....

AI Technical Summary

Problems solved by technology

[0004] The disadvantages of the above method are: First, the longer the program runs, the lower its process priority will be.

The characteristic of the resident program is that the program keeps running after booting, and restarts after being terminated by the system, occupying memory for a long time, and this will reduce the reclaimable memory of the system at the same time

[0006] In other words: 1. If it is not set as a resident program, the longer the program runs, the easier it is for the program to be terminated by the system, which may cause its work to never be completed normally;

[0007] 2. Set it as a resident program, which can avoid being forced to end by the system, but it occupies memory for a long time, and at the same time reduces the reclaimable memory of the system
