Part is contrasted with the All Files in the complete APK of the second edition, and obtaining at least one file destination includes：By first version
The complete APK and complete APK of the second edition in All Files name identical file contrasted；If there is inconsistent
File, then the corresponding document in first version and the second edition is designated as replacing the file destination of type.
For example there is file icon.jpg in the APK of 1.0 versions, this document is replaced in 1.1 versions, but
Will its be named as icon.jpg.The filename of both of these documents is although identical, but actually different, therefore by APK
, it is necessary to be replaced to the icon.jpg in the APK file of 1.0 versions during by 1.0 version updatings to 1.1 version.Therefore at this
In embodiment, All Files name identical file in new and old two versions is contrasted correspondingly, if unanimously, then
Do not carry out any treatment；If inconsistent, then two files just are all designated as replacing the file destination of type.
On how judging the whether consistent problem of two files, The present invention gives a kind of accurately and easily side of judgement
Method：In one embodiment of the invention, in the above method, by the complete APK of the complete APK of first version and the second edition
All Files name identical file carry out contrast and include：To in the complete APK of first version and the complete APK of the second edition
All Files name identical file, obtains the crc property values of each file respectively；By the complete APK and the second edition of first version
Complete APK in All Files name identical file crc property values contrasted.
APK is a kind of compressed package of special zip forms, and in APK, each file has a unique crc
Property value.Crc property values are generated according to CRC (Cyclic Redundancy Code, CRC) algorithm, typically
For, crc property values can serve as the completeness check of APK, that is, judge whether APK is modified.Utilize in the present embodiment
The characteristics of crc property values change after file modification, to file famous prime minister in new and old edition with file, first from respective
The crc property values of file are read in APK, crc property values is contrasted afterwards whether identical, it is possible to rapidly and accurately judge new old edition
Whether the file of the same name in this is identical file.
In one embodiment of the invention, in the above method, by the All Files in the complete APK of first version and
All Files in the complete APK of two versions is contrasted, and obtaining at least one file destination includes：If a file is present in
In the complete APK of first version, and this document is not present in the complete APK of the second edition, then this document is designated as into newly-increased class
The file destination of type.
In one embodiment of the invention, in the above method, by the All Files in the complete APK of first version and
All Files in the complete APK of two versions is contrasted, and obtaining at least one file destination includes：If a file is present in
In the complete APK of the second edition, and this document is not present in the complete APK of first version, then be designated as this document deleting class
The file destination of type.
Both the above is implemented to be illustrated two kinds of situations for updating and packing and be likely to occur during work：Increased newly in redaction
File, or delete the file being originally present in legacy version.It is marked as newly-increased type respectively in the above embodiments
With the file destination for deleting type.
As it was noted above, there may be replacement, file destination that is newly-increased and deleting type in embodiments of the invention.And it is every
The file of type has corresponding renewal to pack to operate, shown below is some examples：
In one embodiment of the invention, in the above method, according to the type of the pending file for updating operation, perform
It is corresponding with the type renewal pack operate including：File destination to replacing type, by all file destinations respectively from each
From APK in solution press out, calculation document name identical file destination between difference, by result of calculation add update bag so that
Update bag when mounted, corresponding file destination is replaced in the APK according to result of calculation to the second edition；To increasing type newly
File destination, by the APK of first version file destination add update bag, and update bag in mark to this document perform
Addition operation, so as to update bag when mounted, corresponding file destination is added in the APK of the second edition；To deleting type
File destination, update bag in mark to this document perform deletion action so that update bag when mounted, by corresponding target
File is deleted from the APK of the second edition.
For the file for replacing type, the data volume of bag is updated to reduce, be not by the file destination in redaction
It is added directly into renewal bag, but calculates its difference with respective objects file in legacy version, the size of this result of calculation
The size of file destination typically less than in redaction.Calculated, it is necessary to first be decompressed file destination to perform.At this
In one embodiment of invention, the difference between calculation document name identical file destination includes：Text is calculated using bsdiff algorithms
Difference between part name identical file destination.Bsdiff algorithms are a kind of two-stage system difference algorithms, can calculate two targets
Difference between file.
For the file destination for deleting type, marked in bag is updated and deletion action is performed to this document, for example, only marked
Deletion action is performed to tri- files of a, b, c, without these three files are put into renewal bag.For the target for increasing type newly
File, then be that the file destination in the APK by first version adds renewal bag, and compressed content directly so is added into renewal bag
In, also reduce the data volume for updating bag.
Because the action type that may be performed there are three kinds, operation 0,1,2 can be respectively marked as, so update bag
In be claimed as which file perform which kind of operation it is also more simple, certainly, it is also desirable to update bag in write call corresponding operating
Specific code.
In one embodiment of the invention, the above method also includes：Renewal bag, the version letter of first version that will be obtained
The version information correspondence of breath and the second edition is preserved.
For an application, the quantity of its version is probably more, and in uncontrollable each android terminal
The application of installation is all secondary new version.For example, newest version is 1.3, however it is necessary that the version for updating is 1.0,1.1,
1.2.Therefore according to above-described embodiment, it is necessary to make respectively by the renewal bag of 1.0 version updatings to 1.3 versions, by 1.1 versions more
New renewal bag to 1.3 versions and by the renewal bag of 1.2 version updatings to 1.3 versions.When updating, it is necessary to first obtain current peace
The version (such as 1.0) installed in tall and erect equipment, then selects the corresponding bag that updates (by the renewal of 1.0 version updatings to 1.3 versions
Bag).So it is accomplished by the preservation of renewal bag, renewal bag, the version information of first version and the second edition that will be obtained
Version information correspondence is preserved, the treatment that can also be serialized to the version information of new and old edition.
Fig. 2 shows a kind of schematic flow sheet of the update method of application according to an embodiment of the invention, such as Fig. 2 institutes
Show, the method includes：
Step S210, obtains the renewal bag of application to be updated；
Step S220, parses to updating bag, determines at least one file destination and corresponding with the type of file destination

Step S230, complete installation kit APK execution and the type pair of file destination to the current version of application to be updated
The renewal answered is operated, and obtains the complete APK of version to be updated.
Step S240, installs the complete APK of version to be updated.
It can be seen that, the renewal bag in the method shown in Fig. 2 can be by the generation side in previous embodiment using renewal bag
Method generation, thus when renewal bag is installed, in addition it is also necessary to get and be mounted with the intelligent terminal of current application to be updated, treat
Update the complete APK of the current version of application.These APK are generally held under system directory, it is necessary to certain authority is obtained
Take.Can perform and update operation according to the parsing to updating bag, the complete APK of the current version of application to be updated afterwards, also
It is that the APK is modified, obtains the complete APK of version to be updated.For example, the current version of application to be updated is 1.0, treat more
Redaction is 1.1, then get the renewal bag of 1.0-1.1 versions, it is possible to realize the method shown in Fig. 2.Therefore at this
In one embodiment of invention, the renewal bag for obtaining application to be updated includes：Obtain the version with application current version to be updated
The information renewal bag corresponding with the version information of version to be updated.Specifically, can obtain application to be updated and work as when updating
The version information of preceding version, sends to updating server, by server according to the version information of application current version to be updated and
The version information (the usually version information of latest edition) of version to be updated, issues corresponding renewal and wraps.
In one embodiment of the invention, in the above method, to the complete installation kit of the current version of application to be updated
APK performs update corresponding with the type of file destination and operates, and the complete APK for obtaining version to be updated includes：Work as file destination
To replace during type, the meter being calculated according to file destination difference in version to be updated and current version is extracted from bag is updated
Result is calculated, corresponding file destination in the APK of current version is replaced；When file destination is newly-increased type, from renewal
File destination is extracted in bag, is added in the APK of current version；When file destination is to delete type, from current version
APK in delete target file.Specifically, result of calculation is to use bsdiff algorithms to version to be updated and current version Chinese
What the difference between part name identical file destination was calculated.
If calculated the APK of two different editions using bsdiff, it is also possible to obtain two differences of version simultaneously
Making renewal bag, but its resource for being consumed when mounted accordingly is greater than the method taken in the present embodiment.
