Problems solved by technology

However, powerful functions also bring performance degradation, such as checking the type and validity of media files, and generating thumbnails for video and picture media files, which will consume a lot of system resources and require more response time. This is unbearable for users who often need to scan media files
[0003] There are many application programs that need to read media files in the Android system, such as picture browsers, slide show programs, screen savers, etc. If you use the media file access function provided by the Android system to obtain the list of media files, especially when When the number of media files is large, it will take up a lot of resources and time, causing users to wait unnecessarily, resulting in a bad user experience

Embodiment Construction

[0025] See figure 1 , Schematically shows an application architecture diagram of a method for generating a media file list in an Android system according to an embodiment of the present invention. In one embodiment, the method of generating the media file list is implemented by the media file list service 104, which obtains a valid media file list from the storage device 106 and provides it to the media file requester 102. The media files include audio media files, video media files, and picture files, such as MP3 files, AVI files, and JPG files.

[0026] When running, the media file requester 102 sends a call request to the media file list service 104, and provides the type and path of the requested media file. The media file list service 104 receives the media file requester After the call request of 102, the media file information matching the requested media file type is obtained from the corresponding path of the storage device 106, a media file list is generated, and the me...

Abstract

The invention relates to a method for generating a media file list in an Android system, which is used for providing the media file list for a media file requester, and comprises the following steps: designating a path with media files; obtaining a list of all the files under the path and recording the path as a first file list; filtering the files in the first file list according to media file extensions, and adding the files with matching media file extensions into a second file list; filtering the files in the second file list according to media file characteristic codes, and adding the files with matching media file characteristic codes into the media file list; and providing the media file list for the media file requester. By adopting the technical scheme, the media file list can be generated rapidly and accurately in the Android system and provided for the requester of the media file list.

Description

Technical field [0001] The present invention relates to the technical field of file processing, in particular to a method for generating a list of media files in an Android system. Background technique [0002] The Android system is a lightweight operating system widely used in portable devices. For example, in digital devices such as mobile phones, handheld players, GPS navigators, etc., it provides powerful media file access functions, which can access audio and video Retrieve and browse various media files such as, pictures, etc. At the same time, it can also generate thumbnails of video and picture media files for users to preview. However, powerful functions also bring performance degradation, such as checking the type and validity of media files, and generating thumbnails for video and picture media files, which will consume a lot of system resources and require more response time. This is unbearable for users who often need to scan media files. [0003] In the Android syst...
