acquiring upgrading identification information carried by the current folder, and judging whether the upgrading identification information meets preset conditions or not;
and if the upgrading identification information meets the preset condition, comparing the current folder with the latest folder.
Specifically, the upgrade identification information is carried by a manifest file of the current installation package, so that the upgrade identification information can be obtained by searching the manifest file, whether the application program can be differentially upgraded or not is determined according to the upgrade identification information, if yes, the two folders are compared, if not, the upgrade is performed in a full-scale mode, and the latest installation package is fed back to the client. In addition, the comparison of the current folder with the latest folder is a classification comparison of files in the current folder with files in the latest folder. Correspondingly, if the upgrade identification information meets the preset condition, comparing the current folder with the latest folder specifically includes:
if the upgrading identification information meets the preset conditions, respectively acquiring the optimized file class, the dynamic library class and the resource class carried by the current folder and the latest folder;
and comparing the optimized file class, the dynamic library class and the resource class of the current folder with the optimized file class, the dynamic library class and the resource class of the latest folder respectively.
Specifically, the optimized file class, the dynamic library class and the resource class are all located on two folder directories, so that the files under the two folder directories are grouped according to the optimized file class, the dynamic library class and the resource class, and the files are correspondingly compared to determine the difference files of each lease. The optimized file class includes a DEX file. The upgrade identification information is version information of the application program. The preset condition is a preset condition for judging whether the application program can perform differential upgrading or not. In this embodiment, the preset condition upgrade identification information exists in an upgrade identification database pre-stored in a server, where the upgrade identification database pre-stored in the server stores upgrade identification information that can be differentially generated. That is, if the current installation package is not configured with the upgrade identification information or the upgrade identification information is not matched with the preset identification of the application program, it is determined that the application program of the client device cannot perform differential upgrade.
