Detailed description of the invention

It is more fully described the exemplary embodiment of the disclosure below with reference to accompanying drawings.Although accompanying drawing shows the disclosure Exemplary embodiment, it being understood, however, that may be realized in various forms the disclosure and should be by embodiments set forth here Limited.On the contrary, it is provided that these embodiments are able to be best understood from the disclosure, and can be by the scope of the present disclosure Complete conveys to those skilled in the art.

Fig. 1 shows the flow chart of the hot restorative procedure that a kind of Android applies, from visitor Side, family illustrates the implementation process of this programme.As it is shown in figure 1, the method includes:

Step S110, obtains the service packs specifying Android application, and described service packs includes: specify repairing in Android application The class file specified after Fu.

Step S120, when specifying Android application to start, loads described service packs.

Step S130, when specifying Android application to need to call the class file specified, calls reparation from described service packs After the class file specified to perform corresponding function.

Visible, when specifying the class file specified in Android application to go wrong to need to be repaired, according to the side shown in Fig. 1 Method, directly obtains the service packs of the class file specified after comprising the reparation specified in Android application, when Android application needs to adjust During with the class file specified, from this service packs, call the class file specified after corresponding reparation, it is achieved that Android application Properly functioning.Compared with prior art, this repair process without experience publisher repack appointment Android application, test, to Each application market and channel change bag, prompting customer upgrade, prompting user download, utilize newly installed cladding lid install specify Android The series of steps such as application, on the basis of not changing the application of former Android, in the way of patch, the application of dynamic restoring Android is tight Anxious problem, significantly reduces the rehabilitation cost of Android application.

In one embodiment of the invention, step S120 loads described service packs to include: according to described service packs institute File directory, construct Classloader, by this Classloader load described service packs.Such as, it is intended that in Android application There is leak in certain class file a.class specified performed in file, for repairing this leak, obtains the benefit specifying Android application Fourth bag patch.dex, this patch.dex include repaired after the class file a.class specified, construct Classloader ClassLoader, by DexClassLoader object, loads by service packs patch.dex.

After service packs is loaded, in order to allow this service packs play the function of dynamic restoring, this programme to be specified When Android application needs to call the class file specified, it is ensured that specify Android application call is the class the specified literary composition in service packs Part, and never call the class file specified specified in Android application in original execution file.For realizing this purpose, need reason The operation principle of solution Android system:

In Android system, Classloader can load multiple execution file, the added multiple execution carried of this Classloader File arrangements becomes an orderly loading set, and the added each execution file carried of this Classloader is the equal of this loading set In an element, when different during this loads set perform the class file having repetition in file, when needs call this During class file, the class file that system meeting prioritizing selection loads in the order preceding execution file in set calls.Foundation This principle, so that the class file specified in service packs is preferred and calls, the service packs after loading should occupy phase The preceding element position of sequence loaded in set answered.

Therefore, on the basis of above-described embodiment, further, step S120 loads described service packs also to include: obtain Taking the first loading set that the process loading described service packs is corresponding, described service packs is in this first loading set Only element；Obtain the second loading set corresponding to the process specifying each execution file in Android application to load, refer to Each file that performs in Dingan County's Zhuo application is the element in this second loading set；Load set and second by first and load set Merge into one and load set so that described service packs is as first element in this loading set.Such as, to service packs The first loading collection that patch.dex carries out the process that loads corresponding is combined into subordinate ordered array dexElements1:{patch.dex}, Service packs patch.dex comprises the a.class after reparation, adds specifying each original execution file in Android application Second loading collection corresponding to the process that carries is combined into subordinate ordered array dexElements2:{classes1.dex, classes2.dex, Classes3.dex ... }, classes2.dex wherein comprises original a.class not repaired, subordinate ordered array DexElements2 has i.e. loaded specifying Android application to start when；Getting service packs patch.dex and carrying out After loading, subordinate ordered array dexElements1 and subordinate ordered array dexElements2 are merged into one and load set so that First element that service packs patch.dex gathers as this loading, i.e. loads collection and is combined into: patch.dex, Classes1.dex, classes2.dex, classes3.dex ... }, Android system can call by prioritizing selection the most when needed A.class in patch.dex replaces calling the a.class in classes2.dex.Wherein, specifically, can be in order to By calling DexUtils.injectDexAtFirst () method, service packs is inserted into loading with the reflex mechanism of Android system The foremost of set dexElements.

Then step S130 of method shown in Fig. 1 is when specifying Android application to need to call the class file specified, from described benefit Fourth bag calls the class file specified after reparation and includes to perform corresponding function: need to call a class when specifying Android application During file, according to the described order of elements loading set, the class file called required for lookup from each element successively；If Find the class file needing to call, stop searching, directly invoke this class file and perform corresponding function；If not finding needs The class file called, jumps to next element and searches the class file needing to call, till finding.Such as, in utilization Literary composition example in build loading set patch.dex, classes1.dex, classes2.dex, classes3.dex ... }, Specify Android to apply in running, when needs call a class file, the order of elements gathered according to this loading, first from Patch.dex searches the class file needing to call, does not finds, then from classes1.dex, search the class needing to call File, by that analogy, until finding, stops searching；When specifying Android application to need to call a.class, add with current Carry the order of set, after all first begin look for a.class from patch.dex, it is ensured that the class file quilt after the reparation in service packs Call.

According to above-mentioned embodiment, this programme is bundled to a dex by specifying the class file gone wrong in Android application In file, obtain a service packs patch.dex, by loading, reflecting, this patch.dex is inserted into ClassLoader pair The foremost loading set answered.In a specific embodiment, when class a.class specified called in service packs time Wait, it is intended that the operation of Android application goes wrong, and reason is: specify Android application call original execution file B.class in classes2.dex, owing to b.class refer to a.class, then specifies Android application to need to call further A.class, is now positioned at before loading set due to service packs, then directly invoke in service packs patch.dex is repaired After a.class, wherein, b.class refer to a.class, b.class in classes2.dex, and a.class exists In patch.dex, it is intended that the execution file at two class file places with adduction relationship of Android application call differs, peace Tall and erect system reports an error, malloc failure malloc.For solving this problem, this programme have extensively studied the operating mechanism of Android system, finds: Android Applying when calling class file, Android system is to the execution file at the invoked class file place with adduction relationship whether phase With the premise carrying out checking it is: if person who quote (b.class in example the most above) this class has been labeled with CLASS_ ISPREVERIFIED identifies, then whether the class file that this class file is cited with it will be held by Android system same Style of writing part checks.

But this CLASS_ISPREVERIFIED mark is when specifying Android application to start, Android system is to specifying peace Class file in tall and erect system is the most all quoted and is stamped after the class file in same execution file verifies, the most not Yes meets this verification condition for the class file with adduction relationship in the Android application of variation, the most all will be labeled with CLASS_ISPREVERIFIED identifies.Then in order to avoid reporting an error when specifying the class file in Android application call service packs, In one embodiment of the present of invention, when will prevent specifying Android application to start, Miscellaneous Documents is labeled with CLASS_ ISPREVERIFIED identifies, and the method shown in Fig. 1 farther includes:

Before specifying Android application to start, obtain a third party and perform file, this third party is performed file and puts into Specify in the specified file catalogue of Android application；In each Miscellaneous Documents performed in file specifying Android application, injection refers to Show that this class file performs, to described third party, the code that file is quoted；When specifying Android application to start, first load described Third party's file, reload specify Android application in respectively perform file.Such as, obtain a third party and perform file Hack.dex, it can be empty realization that this third party performs file, and this hack.dex puts into the specified file specifying Android application In catalogue, inside the constructed fuction of all class files specifying Android application, all inject one section of code, this section of code instruction class Hack.dex is quoted by file, when specifying Android application to start, first passes through and calls loadPatch method by hack.dex Dynamic load is come in, reload specify Android application respectively perform file, so, when Android system carries out starting verification, often Individual class file has adduction relationship to hack.dex, hack.dex but with Miscellaneous Documents not in same execution file, therefore, all kinds of File does not meets verification condition, will not be labeled with CLASS_ISPREVERIFIED mark, so, apply in follow-up appointment Android Would not occur when calling the class file in service packs reporting an error.

In said process, in each Miscellaneous Documents performed in file specifying Android application, inject and indicate this class file Described third party performs the code that file quotes include: arrange an Exclude Lists；Obtain and specify in Android application Each class file, it is judged that whether this class file hits described Exclude Lists, if it does not, inject such literary composition of instruction in this class file Part performs, to described third party, the code that file is quoted；If it is, not injecting codes in this class file.

Wherein, the entrance that Application applies as Android, loading third-party perform file hack.dex be Perform in onCreate in Application, i.e. Application is before loading third-party performs file hack.dex It is loaded, has quoted third party perform the generation of file if injecting instruction in the offspring class file of Application class file Code, can cause third party to perform file and be marked as not existing, even if subsequent load hack.dex, can not change it and not deposit Labelling, it is thus impossible to inject described code in the offspring class file of Application class, in the most described Exclude Lists wrap Include: the offspring class file of the Application class file in specifying Android to apply.

The most in one embodiment of the invention, third party is quoted due to instruction unimplanted in the class file in Exclude Lists Performing the code of file, this class file is necessarily labeled with CLASS_ISPREVERIFIED when Android system carries out and opens verification Mark, it is impossible to this class file is repaired, in the most described service packs by calling the respective class file in service packs again The class file specified after reparation does not include the class file in described Exclude Lists.

In one embodiment of the invention, the class file specified after each reparation in described service packs includes: The identification information of the class file specified after this reparation；Then the class file specified after calling reparation from described service packs is held Before row corresponding function, the method shown in Fig. 1 farther includes: judge the identification information of the class file specified after this reparation with The identification information of the class file specified accordingly is the most identical, is, calls the class file specified after this reparation, otherwise stops Call the class file specified after this reparation.Visible, the present embodiment comes class file essentially by unique mark of class file Confirming, the identification information of class file can be the digital signature of this class file, such as the MD5 of this class file, is calling patch During repaired a.class in bag patch.dex, verify the MD5 of this repaired a.class and specify in Android application The MD5 of original a..class is the most consistent, is then, replaces specifying Android by calling the a.class in patch.dex The calling of original a.class in application, repairs the a.class gone wrong.

In one embodiment of the invention, the class file specified after each reparation in described service packs includes: The description information that the class file specified after this reparation is applied about Android；The then finger after calling reparation from described service packs Before fixed class file performs corresponding function, the method shown in Fig. 1 farther includes: judge to specify whether Android application meets this The description information that the class file specified after reparation is applied about Android, is to call the class file specified after this reparation, no Then stop the class file specifying after calling this reparation.Visible, the present embodiment is essentially by the class file in service packs About Android application description information confirm this service packs target reparation application, the class file in service packs about Android The description information of application can be the version number of Android application of the head annotation at class file, the module title of Android application Deng.Android is specified to apply after loading service packs, if it is judged that the class file in this service packs is about retouching that Android is applied Information of stating is inconsistent with appointment Android application, then deleted by the service packs of this loading.

In one embodiment of the invention, described service packs can generate and be issued to this locality, institute at server State service packs to generate in client this locality, be determined on a case-by-case basis.And, third party perform file can be Server generates and is issued to this locality, and third party performs file and can also generate in client this locality, depending on concrete condition Depending on.

In one embodiment of the invention, the method shown in Fig. 1 farther includes: starting if specifying Android to apply After Preset Time in collapse, unload described service packs.Such as, it is intended that after Android application starts, load service packs Patch.dex, is carried out the former class file in specifying Android to apply by calling the repaired class file in patch.dex Repair, but, if specifying Android application to collapse within upon actuation 20 seconds, i.e. it is considered service packs patch.dex Caused, this service packs patch.dex is deleted, rolled back to original state by specifying Android application.Visible, institute of the present invention The hot-fixing provided should be used to say that reversible for Android.

Fig. 2 shows the flow chart of the hot restorative procedure that a kind of Android applies, from clothes Business device side illustrates the implementation process of this programme.As in figure 2 it is shown, the method includes:

Step S210, generates the appointment Android application after repairing, and obtains all kinds of literary compositions in the appointment Android application after repairing Part.

Step S220, retains the application of preprosthetic appointment Android, obtains all kinds of literary compositions in the application of preprosthetic appointment Android Part.

Step S230, during the Miscellaneous Documents in the application of appointment Android after repairing is applied with preprosthetic appointment Android Miscellaneous Documents compares.

Step S240, for each class file, if the content of this class file changes before and after repairing, then such literary composition Part is the class file specified.

Step S250, puts in patch file by each repaired class file specified, and generates service packs.

Wherein, the repaired class file specified is i.e. the class file specified in the appointment Android application after repairing.

Step S260, is issued to client by described service packs, client load described service packs with to specifying Android Application is repaired.

Visible, that the method shown in Fig. 2 is used in server side generates each embodiment of method shown in Fig. 1 service packs, The principle generating service packs is: in the class file during relatively preprosthetic appointment Android is applied and the appointment Android application after reparation Class file, for same class file, if the content of this class file repair before and after change, illustrate that this class file exists There is a problem before reparation, this class file in the application of appointment Android after reparation is repaired class file, to all processes The class file repaired is packed, and generates service packs, the service packs of generation is issued to client and repairs.With prior art Compare, this programme without the appointments Android application after repairing is carried out the packing of entirety, test, channel issue, but utilization The increment of the class file in the application of appointment Android before and after reparation positions the class file needing to carry out catching, and generates corresponding benefit Fourth bag so that client utilizes this service packs to repair pointedly, the most time saving and energy saving, had both met exploitation demand, and also could Strengthen Consumer's Experience.

In one embodiment of the invention, if the class file in the application of preprosthetic appointment Android is obscured, Then the method shown in Fig. 2 farther includes: retain the class file in the application of preprosthetic appointment Android obscures mapping relations；Then The Miscellaneous Documents in the application of appointment Android after repairing in step S230 and all kinds of literary compositions in the application of preprosthetic appointment Android Part compares and includes: for each class file in the appointment Android application after repairing, obscure mapping relations according to described, really Class file in fixed corresponding preprosthetic appointment Android application, whether the content comparing class file becomes before and after repairing Change.Such as, the class file in the application of preprosthetic appointment Android is obscured by progard obfuscator, generates a class File obscure mapping relations mapping, this mapping indicates the transformation relation obscuring before and after's class file, such as mapping In indicate former a.class and be transformed to x.class, former b.class and be transformed to m.class, get the appointment Android after reparation Miscellaneous Documents in application is: repaired a.class, repaired b.class, is carrying out the a.class before and after repairing Time relatively, first to know the corresponding preprosthetic a.class of x.class according to mapping, then judge the a.class before and after repairing Content whether change, for b.class the most in like manner, repeat no more.Further, service packs is being issued to visitor After the end of family, when the class file in service packs is made a look up and to call by client, need determine according to mapping and specify peace The repaired class file specified in the service packs that the class file specified after obscuring in Zhuo Yingyong is consistent.

In one embodiment of the invention, if preprosthetic appointment Android application in each class file content with MD5 value represents, the method shown in Fig. 2 farther includes: calculate each class file interior during the appointments Android after repairing is applied The MD5 value held；The Miscellaneous Documents in the application of appointment Android after then step S230 will be repaired is applied with preprosthetic appointment Android In Miscellaneous Documents compare and include: each class file during the appointments Android after repairing is applied, by this class file MD5 value compares with the MD5 value of the class file in the application of corresponding preprosthetic appointment Android.
