Research And Implementation Of Updating Offline Resource Based On Differential Algorithm

Some large groups are involved in insurance business,banking business,investment business,etc.The technical department has developed hundreds of mobile applications to support business development.It releases some new functions or fixes some problems in the old version by publishing new version of the mobile application.However,the upgrading rate of the application cannot be effectively guaranteed,so that some functions or bug fixes in new version cannot reach the users which installed the old version.In order to improve the upgrading rate of mobile applications,many technical departments use the Hybrid mode to develop mobile applications.This thesis develops a set of offline resource update platform based on differential algorithm by studying various program update methods and combining the architecture characteristics of Hybrid mode.This article first reviewed the common mobile program update technologies and methods,analyzed the application environment and advantages of various technologies and methods,and provided reference for designing offline resource update solutions;then investigated the needs of various mobile applications for update and analysis The mobile application developed based on the Hybrid mode,the update method for the shortcomings of the offline resource update,completed the design of the offline resource update program based on the difference algorithm;secondly,according to the program,designed and implemented an update patch generation,Manage and release the platform.The patch file is generated by the differential algorithm,which not only improves the efficiency of patch file generation,but also reduces the size of the patch file.Finally,through the test and test,the advantages of the update platform developed in this thesis and other update programs are compared,Features,etc.
