Describe in detail one by one：
Referring to Fig. 1, there is disclosed the realization principle of invention software upgrading difference packet acquisition methods, including following step
Suddenly：
S11：Installation kit and AKU internal structure are parsed, it is determined that the file and AKU of the same name that have differences each other are relative
In the newly-increased file of installation kit, and generate the configuration file for recording those file location informations
Zip file structure is mainly made up of three parts, including central directory, central directory end of identification and compression source document
Part.Wherein central directory is made up of multiple subdirectories, the corresponding compression catalogue source data of each subdirectory, records the specific item
The description information of record.It is as shown in the table referring to table 1, its internal structure：

| Extended field | Indefinite length n | 46+m |
| File notes | Indefinite length k | 46+m+n |
The central directory subdirectory structure of table 1
Installation kit and AKU internal structure are parsed, contrasts the central directory information of installation kit and AKU, detailed process
For：Compare the filename field of each subdirectory of the central directory of installation kit and AKU successively；If there is identical, then
Compare the CRC-32 check codes field of central directory and the field of uncompressed size, all same is then corresponding to corresponding sub directory difference
It is installation kit and the file of the same name having differences in AKU to compress source file, that is, changes file；Differ then corresponding specific item
Compression source file corresponding to record respectively is the file of the same name of installation kit and AKU indifference, i.e. same file；If installation kit
Middle presence and be not present in AKU, then compression source file is to have been deleted in AKU relative to installation kit corresponding to the subdirectory
The file removed, that is, delete file；If being not present in installation kit and existing in AKU, compression source document corresponding to the subdirectory
Part is relative to the increased file of installation kit, i.e., newly-increased file in AKU.
The fileinfo not being related to due to the deletion file of installation kit in AKU, therefore any respective handling need not be done, can
As irrelevant contents.Modification file and same file belong to the fileinfo that reduction AKU needs to use, therefore need to record peace
Modification file location information in dress bag, as residual quantity configuration file；Record simultaneously and file and same file are changed in AKU
File location information is increased in positional information, and AKU newly, as merging configuration file.The positional information refers specifically to, each
The information such as local header offset, file byte length corresponding to file.Residual quantity configuration file and merging configuration file are collectively referred to as
For configuration file.
Below in relation to configuration file, residual quantity configuration file and merge configuration file description unless otherwise specified, refer both to this
Locate the configuration file, residual quantity configuration file and merge configuration file.
S12：All internal structural informations of AKU are recorded, generate meta data file
Zip file can be comprising multiple using different compress modes even uncompressed document entity, wherein each file
Entity structure is by local file head (Local File Header), file data (File Data) and data descriptor
(Data descriptor) three parts form.Wherein when the 3rd position position of local file header, the afterbody of document entity structure
Data descriptor just occurs, after compressed data last byte, is served only for that the zip file of output can not be carried out
The situation of retrieval.
, will be right in AKU in order to obtain the structural information of AKU because reduction AKU needs to carry out data merging
It should be had differences in installation kit or the document entity of the same name of indifference is split, the local file head of gained document entity, data are retouched
Symbol, and the meta data file of the composition AKU such as the central directory of AKU, central directory end of identification are stated, is upgraded for recording
All internal structural informations of bag.
S13：The file of the same name having differences of decompression installation kit and AKU, will have differences described in both
File of the same name difference is correspondingly carried out in the form of source data to obtain differential data file
The existing method for obtaining difference packet, is mainly based upon the installation kit and AKU to not decompressing source data, passes through
Difference algorithm directly carries out binary system difference, but because the file source data of zip file structure is after encoded compression, leads
Cause the binary code of source data to carry out complicated rearrangement, put so as to cause AKU to be mounted opposite the actual less difference of bag
Greatly.For example AKU is mounted opposite bag only change certain module or some bytes, both actual variances are those by more
The module or byte changed, but it is encoded after, all data of installation kit and AKU are rearranged with new rule, cause two
Person's difference amplify, so as to get delta package volume increase.Therefore, in order to obtain the difference packet of smaller volume, the present invention using pair
The source data decompressed in installation kit and AKU carries out difference, i.e., carries out binary system difference to un-encoded initial data,
Less actual variance between the two is obtained, generates smaller volume difference packet.
Using general decompression algorithm, the text of the same name being had differences each other in installation kit and AKU is decompressed in order successively
The document order of the same name the having differences arrangement of part, wherein installation kit and AKU should be consistent, by the file source data of decompression
Difference is correspondingly carried out according to same file name.Difference algorithm herein can use xdelta3, bsdiff, courgette etc. to calculate
Method, the present invention illustrate only by taking bsdiff as an example to the differential process.
The jni of android system provides bsdiff differential interfaces：public native String bsdiff(String
OldFilePath, String newFilePath, String patchFilePath), wherein oldFilePath represents storage
The source data file path for corresponding to the file of the same name that AKU has differences of installation kit, newFilePath represent that storage rises
The source data file path for corresponding to the file of the same name that installation kit has differences of level bag, patchFilePath represent that storage is poor
The file path of data is measured, calls the interface to obtain both different informations, i.e. differential data file.
S14：The configuration file, meta data file, differential data file and the newly-increased file are compressed, described in acquisition
Upgrade difference packet
Due to zip file can include it is multiple using different compress modes even uncompressed document entity, then installation kit
There may be following several situations with identical file data in AKU：(1) installation kit data compression and upgrade bag data
Do not compress；(2) installation bag data is not compressed and AKU data compression；(3) bag data is installed and upgrading bag data is compressed；
(4) bag data is installed and upgrading bag data is not compressed.Situation is planted for (2) and (3), it will usually because of CPU versions, is
The reason such as system kernel version difference and its compression parameters difference causes different compressed encoding results, if simply will be uncompressed
Data weight is contracted, and complete zip bags are reassembled into differential data, AKU metadata, obtained residual quantity AKU and former AKU
It is inconsistent, or even very big difference is had, so as to cause the further upgrading subsequently based on the new AKU of the restructuring to be affected.
In addition, but because installation kit is different with AKU compression parameters, and the compression ginseng of different zip bags can not be known
Number, therefore in order to solve the above problems, the compression consistent with AKU is realized, the present invention is to unpressed number of files in installation kit
It is compressed according to using certain compression parameters, obtained compression result same file contrast corresponding with AKU, if complete
It is complete otherwise to continue to be adapted to using new compression parameters unanimously then to be adapted to successfully, until finding the compression ginseng consistent with AKU
Number.The compression parameters that above-mentioned adaptation obtains, which also recorded, to be merged in configuration file.
Differential data file, the AKU obtained to above-mentioned steps increases file, AKU meta data file, residual quantity configuration newly
File and merging configuration file are compressed, and obtain the smaller compression difference packet of volume.Wherein, differential data is by installation kit
Obtained with the source data difference for the file of the same name being had differences each other in AKU, therefore differential data is unpacked data, institute
To be also required to be compressed it to obtain the packet of smaller volume.
