Android system-based file scanning method and device

Abstract

The invention discloses an android system-based file scanning method and device. The method comprises the steps of background scanning of a first stage, adopted when a storage device is mounted, and foreground scanning in a second stage, triggered when entering a local application, wherein in the background scanning step, when file scanning is executed, current CPU condition is read, if a CPU is busy, first preset time is waited and then scanning is carried out, when a catalog is accessed, the current memory condition is read, if a memory is low, the current scanning catalog is recorded, and all recursion catalogs are exited, all memories are released, and the catalogs are re-accessed for scanning; and in the foreground scanning of the second stage, when a file catalog corresponding to a database is accessed, the bottom scanning is called for scanning all files to be scanned, which are not scanned in the background scanning step under the catalog and the scanned files are updated in the database. According to the invention, scanning efficiency is increased and waiting time of a user is greatly saved.

Description

technical field [0001] The invention relates to the technical field of electronic storage device scanning, in particular to a method and device for scanning files of a storage device based on an android system. Background technique [0002] Android is a new-generation intelligent platform, and more and more electronic terminals use Android as an operating system, so that the number of users of electronic terminals with the Android system is increasing day by day. At the same time, with the development of technology, storage devices tend to be diversified, especially after the Android system is applied to TVs, for high-definition movies with several gigabytes, storage devices have changed from traditional SDcard and USB devices to large-capacity devices commonly used today. Mobile hard disk. So now the Android system is particularly important for the scanning support of multimedia files in various storage devices. [0003] When the storage device is mounted on the Android s...

AI Technical Summary

Problems solved by technology

[0020] One is that there are too many files and the scanning directory is very deep. The existing method of recursively querying files will easily consume too much memory, mistakenly making the system think that there is a memory leak in the scanning and being killed, making the scanning unstable

[0021] The process of obtaining thumbnails in the second scan needs to be decoded, which consumes more CPU. If the CPU usage of the system is already high at this time, it is necessary to perform scanning actions. Scanning a large number of files will keep the system busy for a long time. The operation process is relatively stuck, which will inevitably make the user think that the system has crashed
