Method for decompressing large-data-volume package in mobile rich media application

Abstract

The invention discloses a method for decompressing a large-data-volume package in mobile rich media application, which improves the traditional decompressing method on three aspects of specified file entry information acquisition, separation of the specified file entry information acquisition and package decompressing flow and decompressing flow operating granularity division and is suitable for decompressing large-data-volume packages containing more files and large files. In the invention, by reasonably arranging the specified file entry information acquisition which is time consuming and adding acquired entry information of a specified file to a buffer memory, the executing frequency of the step of specified file entry information acquisition which is time consuming, so that the decompressing efficiency for a package with more files can be obviously improved; a longer process for decompressing the specified file in the package is divided into a plurality of smaller executing processes, and under the condition of a single thread, a package containing a large file is decompressed by a UI (User Interface) event in platform environment of a mobile terminal system without being blocked for a longer time so as to bring good user experience to a user of a mobile terminal rich media application.

Description

technical field [0001] The invention belongs to the technical field of decompression of compressed data packages, and more specifically relates to a method for decompressing compressed packages with a large amount of data in mobile rich media applications. Background technique [0002] With the popularization of smart phones and the arrival of 3G and beyond 3G era, various applications are continuously launched. Driven by all aspects of the industry chain, the Internet has moved from computers to mobile phones and other mobile terminals. Mobile Internet is no longer limited to applications such as pictures, ringtones, news, and information on WAP. Blogs, search, and communities have already extended to mobile Internet services. Experience it anytime, anywhere. [0003] It can be seen that the content of the mobile Internet will also become massive, and the mobile rich media application is the most typical service and display form of massive information in the mobile Intern...

Problems solved by technology

[0023] From the above process, we can easily find that the operation of obtaining the entry information of the specified file is repeated in the process of actually decompressing the specified file data and only obtaining the entry information of the specified file, resulting in a loss in efficiency

In addition, the actual operation of decompressing the specified file must immediately follow the operation of obtaining the file entry information, so that the previously obtained specified file entry information cannot be used by this decompression operation, which also causes unnecessary loss of efficiency

In particular, when decompressing a specified file of a large file, LiteUnzip can only decompress the entire file at one time, which can easily cause UI event blocking
