Application priority management method, device and system, and storage medium

Abstract

The invention provides an application priority management method, device and system, and storage medium. The application priority management method comprises the steps of loading a process priority configuration file; according to the process priority configuration file, establishing a process priority mapping table; when an application process is started, marking a priority of the process according to the process priority mapping table; according to the priority of each process, dynamically adjusting a priority threshold of the application process; and when a system resource recycling mechanism is triggered, preventing the application process with the high priority from being recycled by a system. Therefore, the application process of a core function in a vehicle-mounted navigation product can be ensured not to be recycled by the system in a long-time running process; and the core function of the vehicle-mounted navigation product is ensured to continuously and reliably run.

Description

technical field [0001] The invention relates to the technical field of application process management, in particular to a method, device, system and storage medium for application process priority management. Background technique [0002] Existing Android system application process, including system service, built-in application service and foreground service and so on. In addition to core system services, other built-in application services or other system services may be recycled by the system after other built-in application services or other system services run in the background of the system for a period of time, resulting in the termination of the function of the APP running in the background. [0003] In car navigation products with Android system installed, some core functional modules need to run continuously for a long time without being stopped by the system, so the default process management of the native Android system is not suitable for use in car navigation p...

Problems solved by technology

In addition to the core system services, other built-in application services or other system services may be recycled by the system after other built-in application services or other system services run in the background of the system for a period of time, resulting in the termination of the function of the APP running in the background

[0003] In car navigation products with Android system installed, some core functional modules need to run continuously for a long time without being stopped by the system, so the default process management of native Android system is not suitable for use in car navigation products

For example, the map navigation APP often needs to run in the background for more than 100 hours. When the CPU and memory resources of the car navigation product are limited, the map APP process is likely to be recycled by the system to release resources, resulting in the map function not being used normally and continuously.
