Abstract

The invention discloses multi-task concurrent processing method and device for an Android system. The method includes: after receiving a new incoming task, a concurrent processor judges whether the number of current threads is smaller than a set maximum thread number or not; if yes, after the new incoming task is put in a running queue, one current thread is created for the new task and used for executing the new incoming task; if not, the new incoming task is put in a ready queue; if the current thread created by the concurrent processor is executed, the top task in the ready queue is moved to the running queue by the concurrent processor, and one current thread for executing the task is created for the task; and if the current thread created by the concurrent processor is suspended or abnormal during execution, the current thread is moved to a suspension and anomaly queue and is then moved to the ready queue when an onRestart command is received.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a multi-task concurrent processing method and device for an Android system. Background technique [0002] The multi-task concurrent execution of the existing Linux-based Android system refers to the process of dividing the program into multiple separate and independently running tasks, and making the multiple independently running tasks "synchronously" execute. With multithreading, each task executed concurrently is driven by a corresponding thread. Concurrent execution of multiple tasks makes the program respond faster. [0003] When the existing Android system executes multiple tasks concurrently, it will create threads equal to the number of tasks to perform corresponding tasks. Since the time allocated by the system to each thread is equal, when one or some threads have too much computation, the thread cannot be completed within the allocated time. If the system is ...
