In order to make the purpose of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the present invention, is not intended to limit the present invention.
As it is shown in figure 1, in one embodiment, it is provided that a kind of method for upgrading software based on Android system, the method comprises the steps:
Step 101, obtains and updates bag check value.
Step 102, checking updates bag check value.
It is arranged on what the software of Android system was made up of the plug-in unit realizing functional module, software upgrading is also had only to the renewal bag that download plug-in is corresponding, without the software downloading whole redaction, saved the data traffic needed for software upgrading.In the present embodiment, software has saved updating bag check value and being downloaded to local temporary folder by updating bag in server.Update bag check value can be used to judge to identify renewal bag when whether renewal bag is completely downloaded and software starts.If checking updates after bag check value passes through, then show that the renewal bag that plug-in unit is corresponding is successfully downloaded to this locality, upper once start time need to run and update bag.
In one embodiment, updating bag check value is update the informative abstract value that bag is corresponding, step 102, and checking updates bag check value and includes: obtain add-on file clip pack under application data catalogue containing informative abstract value corresponding to plug-in unit；The informative abstract value that informative abstract value corresponding for plug-in unit is corresponding with updating bag is contrasted one by one；If being absent from the informative abstract value that the informative abstract value corresponding with updating bag is identical, being then verified, otherwise, checking can't pass.
In the present embodiment, the informative abstract value that plug-in unit is corresponding refers to and plug-in unit is carried out the character string that digest algorithm obtains.Concrete, informative abstract value is MD5 (_ MessageDigestAlgorithm5, Message Digest 5 the 5th edition), wherein MD5 value stores with the form of key-value pair (key-value), before updating bag download, preserve the MD5 value updating bag correspondence that server returns, after down loading updating bag completes, software can scan after starting has existed the MD5 value that plug-in unit is corresponding, the MD5 value one by one comparison corresponding with updating bag by MD5 value corresponding for plug-in unit, if there is inconsistent MD5 value, then represent in temporary folder that being successfully downloaded to renewal bag needs to run when upper once software starts to update bag.
Step 103, if being verified, by updating in the add-on file folder that bag migrates under the application data catalogue that software is corresponding in temporary folder.
Update bag and refer to the plug-in unit increasing New function into software, or to the plug-in unit that original plug-in unit is upgraded.Add-on file folder is used for program file and resource file essential to storage running plug-in unit.The renewal bag downloaded leaves in temporary folder.Concrete, temporary folder refers to the download folder under the application data catalogue that software is corresponding.If being verified, content in bag can be updated by normal call by updating when bag ensure that running software from the add-on file folder that temporary folder migrates to application data catalogue.
Step 104, decompression updates bag and obtains updating file, updates file and includes: class updates file, local update storehouse and resource updates file.
In the present embodiment, obtain updating file by decompressing the renewal bag that data form is .apk or .jar.Renewal file includes: class updates file, local update storehouse and resource updates file.Class updates in file the program's code file (.Class file or .dex file) comprised and is used for realizing concrete program function.Resource updates file contains except code such as resource files such as picture, word, animation and videos.Local update storehouse comprises the local library file that file format is .so generated after being compiled by c/c++.If updating bag is the upgrading to the existing plug-in unit of software, then renewal file is replaced it the content in the file of front already present same file name.If updating bag is the plug-in unit newly increased, then renewal file is stored under application data catalogue in new folder.
Step 105, adds the store path pointing to local update storehouse in running software attribute.
Step 106, software start after store path according to described interpolation, call the local file in local update storehouse.
Former local library (nativelibrary) for providing public method and interface for running software before software upgrading.Can not be loaded by Classloader owing to updating the local update file in the local update storehouse wrapped, it is necessary to local update file is put in former local library and it could be carried out normal call.But access former local library to need to obtain root authority (the highest weight limit of Android system), in order to the local update file that root authority could be used that in local update storehouse need not be obtained, the operation attribute (java.library.path) of running software adds the store path pointing to local update storehouse.And the operation attribute revising java is to obtain root authority, thus calling local update storehouse during without influence on running software.When needing to use local update storehouse, call the local library file in local update storehouse by the newly added store path pointing to local update storehouse.
Step 107, class described in dynamic load updates file and resource updates file.
In the present embodiment, after receiving running software instruction, dynamically content in renewal file it is loaded into internal memory according to the operation logic of software and performs, change the display of former software or perform logic.Realize the upgrading of mourning in silence to software.
The above-mentioned method for upgrading software based on Android system, it may not be necessary to install and update bag, be modified running software attribute dynamic load can update file after software starts.Owing to amendment running software attribute need not obtain the highest weight limit of Android system, thus this method realizes the upgrading of mourning in silence to software.
