Abstract

The invention discloses a compression method and device and a decompression method and device for installation packages, and relates to the technical field of information. The problems that in the prior art, the compression efficiency of a batch of similar installation packages is low, and the generating compression rate of compression files is high are solved. The compression method includes the steps that standard installation packages are selected from the batch of similar installation packages; informative abstract files of the standard installation packages and informative abstract files of increment installation packages are analyzed respectively and compared, and the increment installation packages are the installation packages which are similar to the standard installation packages but are different from the standard installation packages in the batch of similar installation packages; according to the comparison result, difference files of the increment installation packages relative to the standard installation packages are sought, and a preset difference list is updated according to the difference files and used for recording the difference files between the increment installation packages and the standard installation packages; the standard installation packages and the preset difference list are compressed, and target compression files are obtained. The compression method and device and the decompression method and device for the installation packages are used for compressing and decompressing the installation packages.

Description

technical field [0001] The invention relates to the field of information technology, in particular to a method and device for compressing and decompressing an installation package. Background technique [0002] With the continuous development of information technology, various application programs emerge in endlessly, and the application markets for various application programs are also various. In order to better promote the application programs, application program developers usually publish the installation packages of the application programs to different application markets. In order to facilitate subsequent statistics of downloads, user activity, usage habits, etc. in different application markets, application developers usually need to generate different installation packages for different application markets, so as to distinguish which application market the user downloaded the application from. Since different installation packages for different application markets...
