The flow chart of rapid S2.
As shown in Fig. 2 step S2 is based on new edition application installation file and old edition application installation file, raw
Delta file is become to include：
Step S200 obtains the fileinfo of the file in old edition application installation file.Due to old edition this application journey
Sequence installation file comprises much individual subfiles, so the file chosen in this step can be the random file chosen.For example
Can be E:\a\...\assets\location_public_key.der.
The inquiry of step S201 whether there is the literary composition of the same name under same catalogue in new edition application installation file
Part.The meaning of same catalogue here it should be say relatively the same.The catalogue of such as legacy version installation file decompression is E:A,
The decompression catalogue of redaction installation file is E:B, and in step S200 obtain file catalogue be E:a\c\...\
Assets, and the catalogue of its corresponding redaction installation file be E:B c ... assets, then when comparison here
Higher level's two-stage catalogue of both of these documents should be ignored, in the present invention same catalogue refer to c ... assets identical.
In the case of there is file of the same name under the same catalogue of new edition application installation file, enter step S202 and sentence
Whether disconnected file MD5 value is identical.Before judging whether file MD5 value is identical, first have to generate the MD5 value of two files, can
To generate before implementing in the present invention it is also possible to generate in the decompression procedure of step S1 of the present invention, the MD5 value of file is base
File content in two files generates, and generation method is common method, the present invention no longer describes in detail.
When MD5 value is different then it is assumed that the content of two files has differences, enters step S203 and be based on this two files
Generate corresponding differential file, differential file is processed label information, the file name of this document, store path and differential file
Information of upgrade file as this document writes in the file body of delta file.Here by generalized delta algorithm bsdiff life
Become the differential file of two files, the present invention can also be that other general delta algorithm generates the differential file of two files.
When judging that MD5 value is identical then it is assumed that two files are identical file, entering step S204 will be identical
File process label information, the file name of this document and store path write described increasing as the information of upgrade file of this document
In amount file.
When there is not file of the same name under the same catalogue of new edition application installation file, now legacy version installs literary composition
In part, this file needs to delete, and enters step S205 afterwards and by the file name of this document, store path and deletes at file
Reason label information writes in described delta file as the information of upgrade file of this document.
Complete S203, after the completion of any one step of S204, S205, enter step S206 and judge that old edition application is installed
There is untreated file in file.Here judge to have in old edition application installation file the untreated file can be
By way of traveling through file, the catalogue according to file judges whether currently processed file carries out S201's to S205 above one by one
Process.For example currently processed file is location_public_key.der, and its catalogue is E:A ... d assets, judge
This document needs to delete, then that complete is S200, S201, S205 of abovementioned steps, and step S206 is to first determine whether E afterwards:\
A ... assets whether have file without above flow processing under catalogue, then continue to judge E:\a\...\
Assets catalogue upper level catalogue E:A ... d in whether have the file not carrying out the above file process of flow processing,
Until E:All Files under a catalogue has inquired about the file all not processed then it is assumed that old edition application installs literary composition
There is no untreated file in part.There is untreated file under a careless catalogue, then enter step S207 and obtain legacy version
The fileinfo of next untreated file in application program installation file, return to step S203 afterwards.
If there is no untreated file in old edition application installation file, entering step S208 and obtaining new edition
The fileinfo of the file in application installation file, acquisition here is also random acquisition.E.g. E:b\c\...\
F armeabi xxx.so, afterwards step S209 judge in legacy version installation file whether there is same under same catalogue
Name file.Here the judgement of same catalogue is as judgement above.Legacy version installation file is inquired about less than file of the same name
When then it is assumed that this document is newly-increased file, enter step S210 by the file name of this document, store path, newly-increased file
Reason label information and file data write in described delta file as the information of upgrade file of this document.
Enter step S211 afterwards and judge whether there is untreated file in new edition application installation file.Here
The determination methods of untreated file, as determination methods above, are to determine whether without S209 and S210 step
Processed, if there is no untreated file, then terminated.If there is untreated file, then enter step S212 and obtain
Take the fileinfo of next untreated file in new edition application installation file, return to step S209 afterwards.
Judging when there is the file of the same name being located under same catalogue in legacy version installation file in step S209, no
Process, process ends.
From above-mentioned steps it can be seen that being the delta file based on the file generated after decompressing the present embodiment, delta file
Little.Make server also little to the data of client transmissions, save flow.

Version information, described file body is used for storing the information of upgrade file of each file in new edition application installation file.
Included step S300 before S3, mobile terminal according to the version number of locally stored legacy version installation file and
MD5 value is initiated application program installation file and is updated request.The locally stored legacy version sending mobile terminal to server is installed
The purpose of the version number of file and MD5 value is to be verified (step S301) for server to this legacy version installation file.Verification
Purpose is whether the legacy version installation file of the mobile terminal storage judging to ask upgrading is that official issues.If mobile terminal
The version number of the legacy version installation file of storage in the locally stored version number of legacy version installation file and MD5 value and server
And MD5 value correspondence then thinks that verification is passed through, after verification is passed through, enter the version according to legacy version installation file for the step S302 server
This number corresponding delta file of lookup.The preferred embodiments of the present invention are when software publisher issues latest edition installation file
When, the delta file that will generate latest edition installation file with all legacy version installation files stores on the server, for example,
When the software version that software publisher issues latest edition installation file is V2.3, and the version of legacy version installation file has
V2.0, V1.9, V1.8, V1.0, server will generate the increment of V2.3 installation file and V2.0, V1.9, V1.8, V1.0 respectively
File.Storage is on the server.Can not find appropriate version delta file when, then enter generate delta file program, that is, before
The S1 of face embodiment, S2 step.
After finding corresponding delta file, server to mobile terminal send delta file enter step S3 or, look for
To after corresponding delta file, enter the download address that step S303 server sends delta file to mobile terminal, afterwards
Step S304 mobile terminal downloads delta file according to the download address of the delta file receiving, request, just enters step afterwards
S3.
After completing S3, enter step S4, based on delta file, legacy version installation file is updated obtaining redaction
Installation file.This process is the inverse process of delta file generating process.It is mobile terminal based on its locally stored old edition intrinsic safety
