After receiving an original application package, a server automatically performs splitting and reassembly on the original application package to generate a complete new application package. ## Claims ### Claim 1 A computer-implemented method, comprising: receiving a first application package corresponding to an application; splitting the first application package into a main package and a sub-package, wherein the main package comprises a first page of the main package, and wherein the sub-package comprises a second page of the sub-package; storing the main package and the sub-package in a first file; generating a second application package corresponding to the application, wherein the second application package comprises a header and the first file, and wherein the header comprises a first mapping relationship between the main package and the first page of the main package, a second mapping relationship between the sub-package and the second page of the sub-package, a first offset of the main package within the first file, a first size of the main package within the first file, a second offset of the sub-package within the first file, and a second size of the sub-package within the first file; performing a hash operation on the main package and the sub-package, to generate a first abstract list of the main package for the main package and a second abstract list of the sub-package for the sub-package, wherein the first abstract list verifies the main package, wherein the second abstract list verifies the sub-package, and wherein generating the second application package comprises writing the first abstract list and the second abstract list into the header and signing the header; and synchronizing, to a send port, a download address of the second application package and package information, wherein the package information comprises the first mapping relationship, the second mapping relationship, the first offset, the first size, the second offset, and the second size. ### Claim 2 (depends on 1) The computer-implemented method of claim 1, wherein the main package comprises a meta-information file, and wherein the meta-information file runs the main package and the sub-package. ### Claim 3 (depends on 1) The computer-implemented method of claim 1, wherein the sub-package comprises a first sub-package, wherein the first sub-package comprises a configuration attribute, and wherein the configuration attribute declares whether the first sub-package depends on the main package for running. ### Claim 4 (depends on 3) The computer-implemented method of claim 3, wherein the main package comprises a capability open-up set, and wherein the capability open-up set obtains a meta-information file by the sub-package that depends on the main package. ### Claim 5 (depends on 1) The computer-implemented method of claim 1, wherein the first application package corresponds to a chat application. ### Claim 6 (depends on 1) The computer-implemented method of claim 1, wherein the first application package corresponds to an ANDROID operating system. ### Claim 7 (depends on 1) The computer-implemented method of claim 1, wherein the computer-implemented method is implemented by a server, and wherein the server comprises a content management system. ### Claim 8 (depends on 1) The computer-implemented method of claim 1, wherein the computer-implemented method is implemented by a server, and wherein the server comprises a package process server. ### Claim 9 (depends on 1) The computer-implemented method of claim 1, wherein the computer-implemented method is implemented by a server, and wherein the server comprises a content delivery network. ### Claim 10 (depends on 1) The computer-implemented method of claim 1, wherein the main package comprises a first file size that is greater than a second file size of the sub-package. ### Claim 11 An apparatus, comprising: a memory configured to store instructions; and one or more processors coupled to the memory and configured to execute the instructions to: receive a first application package corresponding to an application; split the first application package into a main package and a sub-package, wherein the main package comprises a first page of the main package, and wherein the sub-package comprises a second page of the sub-package; store the main package and the sub-package in a first file; generate a second application package corresponding to the application, wherein the second application package comprises a header and the first file, and wherein the header comprises a first mapping relationship between the main package and the first page of the main package, a second mapping relationship between the sub-package and the second page of the sub-package, a first offset of the main package within the first file, a first size of the main package within the first file, a second offset of the sub-package within the first file, and a second size of the sub-package within the first file; perform a hash operation on the main package and the sub-package, to generate a first abstract list of the main package for the main package and a second abstract list of the sub-package for the sub-package, wherein the first abstract list verifies the main package, wherein the second abstract list verifies the sub-package, and wherein generating the second application package comprises writing the first abstract list and the second abstract list into the header and signing the header;
