Embodiment Construction

[0056] In order to enable those skilled in the art to better understand the solution of the present invention, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings and implementation manners.

[0057] see figure 1, which shows a flow chart of the compression coding method applied in the embodiment of the present invention, including:

[0058] Step 101, parse the installation package of the application, and obtain the bytecode and resource file of the application.

[0059] Taking the installation package of Android application as an example, the application installation package downloaded by users from the application store generally simply combines executable code and resource files to form a compressed package in zip format, which has a low compression ratio and takes a long time to download.

[0060] The execution program in the installation package is based on the bytecode of the dalvik virtual mac...

Abstract

Provided is an applied compressed encoding method. The method comprises the steps of analyzing an applied installation package, obtaining applied byte codes and resource files; respectively performing compressed encoding on the byte codes and the resource files, and forming compressed files by assembling; and utilizing an LZ77 algorithm to perform compressed encoding on the byte codes. Different compression modes are adopted respectively to encode the byte codes and the resource files, so that the maximal compression ratio can be achieved. The smaller the applied installation package is, under the same download condition, the less the time spent by users is, and the lower the wireless network data flow cost needing paying is.

Description

technical field [0001] The present invention relates to the field of mobile Internet, in particular to an applied compression coding method and device. Background technique [0002] With the increasingly powerful functions of smart terminals, smart terminals have been gradually integrated into people's daily life, and users can download and install various applications through the Internet to expand terminal functions. However, because the installation packages of current applications are very large, generally ranging from several megabytes to tens of megabytes, and the data transmission rate of mobile communication networks is between several kilobytes to tens of kilobytes per second, according to With this rate calculation, if the user does not use WiFi, it will take several minutes or even ten minutes to download an ordinary application. [0003] While spending a lot of waiting time, users also have to pay for the resulting data traffic charges. In addition, due to the ...
