Specific embodiment
Below in conjunction with attached drawing, an exemplary embodiment of the present invention will be described, including the various of the embodiment of the present invention
Details should think them only exemplary to help understanding.Therefore, those of ordinary skill in the art should recognize
It arrives, it can be with various changes and modifications are made to the embodiments described herein, without departing from scope and spirit of the present invention.Together
Sample, for clarity and conciseness, descriptions of well-known functions and structures are omitted from the following description.
Fig. 1 is the schematic diagram of the key step for the method that Android plug-in unit according to an embodiment of the present invention melts hair.Such as figure
Shown in 1, the method that the Android plug-in unit of the embodiment of the present invention melts hair mainly includes the following steps:
Step S101: common code and public resource that each plug-in unit engineering all uses are compiled to generate and rely on packet.
It is host's engineering and at least one plug-in unit engineering by the APP Engineering Division of Android platform, a business module is stood alone as
One plug-in unit engineering only includes code relevant to this business module in the plug-in unit engineering, each plug-in unit engineering is all used
Common code and public resource are generated the independent packet that relies on and exported by code and resource to should be used as common code and public resource,
This independently relies on after packet extended meeting by direct compilation into host's engineering.The dependence packet that the embodiment of the present invention is formed is AAR format,
AAR (Android Archive) packet is Android library item purpose binary system archive file, can be relied on and use by Other Engineering.
Step S102: the source code of host's engineering and dependence packet are compiled packing to obtain host's engineering
Installation kit, by the source code for not including each plug-in unit engineering of the common code and public resource be compiled packing with
Obtain the installation kit of each plug-in unit engineering.In Android exploitation, if having used some third-party code in APP engineering
Library (such as OkHttp, be the open source projects of a processing network request), then OkHttp can be compiled by APP engineering automatically
It goes.The code of plug-in unit engineering itself and resource export to the APK installation kit to form standard, common code and public resource only according to
Rely without being bundled in the APK installation kit of plug-in unit engineering, it is subsequent to pass through the running environment of construction plug-in unit engineering in host's engineering
Carry out the APK installation kit of load operating plug-in unit engineering.
Step S103: it is described each slotting to load and run that load operating environment is constructed in the installation kit of host's engineering
The installation kit of part engineering.After each business module is implemented plug-in unit, the APK installation kit of plug-in unit engineering is not to be mounted directly
On mobile phone, system can not be transferred to directly to handle, the APK installation kit itself of host program is needed to construct a plug-in unit engineering
APK installation kit load operating environment, load and run the resource and code of each plug-in unit engineering by this environment.
Fig. 2 is the system architecture diagram that Android plug-in unit according to an embodiment of the present invention melts hair.As shown in Fig. 2, of the invention
The system that the Android plug-in unit of embodiment melts hair includes host's engineering and multiple plug-in unit engineerings, all by each plug-in unit engineering
The code and resource used is extracted as common code and public resource, and common code and public resource are compiled to be formed solely
Vertical dependence packet, it is subsequent by the dependence packet direct compilation into host's engineering.The APK installation kit of host's engineering, which can be directly mounted at, to be set
It is standby upper, start to construct the load operating environment of the APK installation kit of plug-in unit engineering, plug-in unit after the APK installation kit operation of host's engineering
The APK installation of engineering has been surrounded by after this environment, can have been run when the APK installation kit for using plug-in unit engineering
Come.
The specific implementation compiled in step S102 is described in detail below: Android source code mainly includes code
With resource two parts, so its compiling is also largely divided into two codes and resource part.
Wherein, the compilation process of code are as follows: JAVA source file is compiled into JAVA bytecode, then JAVA bytecode is linked
At Dex (executable file of Android platform) bytecode.Above-mentioned compilation process needs to be aligned the JAR packet of plug-in unit engineering dependence
Carry out normal compilation again afterwards.
Wherein, the compilation process of resource are as follows: be resource, the public resource and each plug-in unit work of host's engineering
Different resource identifications is arranged in the resource of journey, and rule is arranged in the resource of each plug-in unit engineering are as follows: the money of each plug-in unit engineering
Packet mark between the packet mark in source each plug-in unit engineering different and described from the resource of host's engineering, the packet mark of public resource
Knowledge is all different；The packet mark of the system default of each plug-in unit engineering is replaced with to the packet mark of setting.
When searching and locating resource in Android, need to search by unique resource identification (ResourceID),
Resource ID is integer value, the value by the Software Development Kit of Android (Software Development Kit,
SDK the Android resource strapping tool (Android Asset Packaging Tool, AAPT) carried in) generates, specific to tie
Structure are as follows: ResourceID=Package ID+Type ID+Entry ID.Wherein, Package ID is packet mark, for limiting
The source of resource；Type ID is the type identification of resource, each resource type can be endowed a mark；Entry ID is
The mark of resource entity under specific type.
In above-mentioned specific structure, the value rule of Package ID are as follows: the system resource Package of Android platform
ID is equal to 0x01, and the Package ID of user resources is equal to 0x7f, all Package between [0x01-0x7f]
ID is legal.Wherein, user resources refer to developer's resource that oneself is introduced in engineering, such as one of oneself definition
Character string, the picture that oneself is introduced.The value rule of the Package ID of Android platform is shown in Table 1:
Table 1 is the value rule list of Package ID
| System resource | User resources | Legal ID range | |
| Package ID | 0x01 | 0x7f | [0x01,0x7f] |
Separately below by taking system resource and user resources as an example, Resource ID is illustrated: system resource: such as
Public static final int ok=0x01040000；Wherein, 0x01 indicates Package ID, and 04 indicates Type ID,
0000 indicates Entry ID.User resources: such as publicstatic final int app_name=0x7f060001；Wherein,
0x7f indicates Package ID, and 06 indicates Type ID, and 0001 indicates Entry ID.
Referring to above-mentioned background, since public resource meeting direct compilation is into the APK installation kit of host's engineering, to prevent host from providing
There is resource contention (such as host's resource A, public resource B, plug-in unit between any two in source, public resource and different plug-in unit engineering
Engineering C and plug-in unit engineering D, needs to place A, B, C, D and resource contention does not occur between any two), following normal constraint need to be carried out:
(1) public resource uses independent NameSpace, and the PackageID in Resource ID uses system default
0x7f；NameSpace is defaulted as the packet name of APP, for example wraps entitled test.com, then the NameSpace of resource is
Test.com.R, the Bao Mingke are configured in the inventory file of Android；
(2) host's resource uses the NameSpace of system default, and the Package ID in Resource ID uses system
The 0x7f of default, but do not allow the name with public resource identical, i.e. the Type ID of host's resource and public resource or
Entry ID is different；
(3) the Package ID value range of other plug-in unit engineerings is (0x01,0x7f), and each plug-in unit engineering distribution is different
Package ID, thus completely avoid the Resource ID punching between host's resource, public resource and different plug-in unit
It is prominent.The specific allocation rule of Package ID of different plug-in units is shown in Table 2:
Table 2 is the Package ID allocation table of different plug-in units
| Plug-in unit engineering 1 | Plug-in unit engineering 2 | … | Plug-in unit engineering 125 | |
| Package ID | 0x02 | 0x03 | … | 0x7e |
After being compiled to resource, all resources can be generated an integer index by AAPT tool, and be written to
In R.java file.In order to generate Resource ID according to above-mentioned normal constraint, the operation carried out is needed are as follows:
(1) AAPT source code is transformed, to realize when the Package ID write-in of plug-in unit engineering, is replaced
The Package ID of oneself distribution is written in the 0x7f of system default.Specific implementation are as follows: increase one newly in AAPT source code --
Apk-packageid parameter recompilates the AAPT tool that generates, what the Package ID use of plug-in unit engineering had been allocated in advance
Value, passes through -- and apk-packageid parameter passes to the parsing of AAPT tool, and such AAPT tool, which just will use, to be passed into
Package ID replaces the 0x7f of system default.
(2) it sets public resource to being only involved in compiling, be not written into the R.java file of plug-in unit engineering.Specific implementation
Mode are as follows: set dependencies for the dependence mode of public resource in Android Studio.Plug-in unit engineering in this way
R.java file in just do not include public resource Resource ID, will not in host's engineering public resource or its
His plug-in unit engineering conflict.
It is divided into the resource and code two of load plug-in unit engineering to the specific implementation of load operating environment in step S103 below
Part is described in detail:
Wherein, load the process of resource: the resource load of Android loads (Resources) class and Assets Reorganization Taking by resource
It manages (AssetManager) class to complete, Resources class and AssetManager class are the systems by constructing when system initialization
The APK installation kit path of APP itself is added by AssetManager class, then give AssetManager class according to
The rule of Resource ID is searched.However, the AssetManager class of system after engineering plug-in unit is not included plug-in unit work
The path of the APK installation kit of journey can not directly be handled by the Resources class of system default and AssetManager class.
Fig. 3 is the flow chart of the resource of each plug-in unit engineering of load according to an embodiment of the present invention.As shown in figure 3, of the invention
The resource of each plug-in unit engineering of load of embodiment, can be realized by following steps:
Step S301: the AssetManager class in the path of the APK installation kit of all plug-in unit engineerings is created.
AssetManager class can not call directly its constructed fuction, can pass through newInstance method construct AssetManager
One example of class calls hiding addAssetPath method by reflection, using the path of each plug-in unit APK file as ginseng
Number is incoming, and the AssetManager class constructed in this way has just held the path of the APK installation kit of all plug-in unit engineerings.
Step S302: customized delegation resource loads (DelegateResource) class, by AssetManager in system
Example replace with creation DelegateResource class example.Oneself define a DelegateResources class after
The Resources class from system is held, the example of the AssetManager class created in step (1) is passed to
In the building method of DelegateResources class, the AssetManager example of system oneself wound has been substituted for thus
The example for the AssetManager class built.
Step S303: the Resources class of system is replaced with by DelegateResource class using Hook technology.Hook
Technology is a kind of technology for changing API implementing result.Specific implementation are as follows:
1. Hook ActivityThread class, by the mResources in ActivityThread class LoadedApk example
The example that member variable is substituted for customized DelegateResources class.APP can be by the APK of installation when starting
Installation kit is converted into the LoadedApk example an of memory object.
2. the mResources member variable in ContextImpl class is substituted for and makes by oneself by Hook ContextImpl class
The example of the DelegateResources class of justice.
3. the mResources member variable of Activity class is substituted for customized by Hook Activity class
The example of DelegateResources class.Activity class by ActivityThread class member variable
MInstrumentation creation, after Activity creation, Hook Activity class.
Wherein, the process of loading code: android system loading classes default is complete by Classloader PathClassLoader
At after PathClassLoader has member variable pathList, APP the starting initialization of a DexPathList type
PathList member variable can hold the Dex bytecode of APP in memory, only need to be by the path of the APK installation kit of plug-in unit engineering
It is added in pathList, it can be by the PathClassLoader of system come loading code.Specific steps are described as follows:
(1) the member variable pathList of the DexPathList type in Hook PathClassLoader；The step
Purpose is the pathList member variable for obtaining PathClassLoader.
(2) Hook calls the loadDexFile method in pathList member variable, by the APK installation kit of plug-in unit engineering
The example in loadDexFile method to generate a DexFile type is passed to the output directory of Dexization；In the step
The result of Dexization can release a .dex be suffix name file, output directory be it is customized, in APP installation procedure mesh
Record is lower；Dex file in APK installation kit eventually creates a DexFile example in memory.
(3) the dexElements member variable of Hook DexPathList class；The purpose of the step is to get step
(1) the dexElements member variable of the pathList in.
(4) the DexFile example generated in step (2) is built into an Element example, by the Element example
It is put into the dexElements member variable of step (3) acquisition.
The method that Android plug-in unit through the embodiment of the present invention melts hair can be seen that public resource and public generation
Code in the independent form for relying on packet is compiled into host's engineering to be supplied to the use of plug-in unit engineering, by plug-in unit engineering code from original work
This is relied on after journey extraction and relies on packet exploitation, reduces plug-in unit enforcement difficulty, smoothly switch the exploitation of engineering centralization can
To plug-in type development mode；The plug-in unit of the embodiment of the present invention melts forwarding method and decouples module, greatly promotes compilation speed, reduces
The probability for compiling error, is greatly improved development efficiency；Using Hook technology, lightweight Hook is carried out to system API, in memory
Middle dynamically load plug-in unit；Dynamic restoring can be carried out when occurring Bug on line to corresponding module, after need to only repairing the plug-in unit engineering
It is deployed to server-side, client downloads the APK installation kit of the plug-in unit engineering from server-side, without issuing new version again；
It may specify that module is upgraded, without updating entire APP.

Shown in 4, the Android plug-in unit of the embodiment of the present invention melts the device 400 of hair, specifically includes that
Packet generation module 401 is relied on, common code and public resource for all using each plug-in unit engineering are compiled
Packet is relied on to generate.It is host's engineering and at least one plug-in unit engineering by the APP Engineering Division of Android platform, one
Business module stands alone as a plug-in unit engineering, only includes code relevant to this business module in the plug-in unit engineering, inserts each
The code and resource that part engineering all uses generate common code and public resource only to should be used as common code and public resource
It is vertical to rely on packet output, this independently is relied on wrap after extended meeting by direct compilation into host's engineering.The dependence that the embodiment of the present invention is formed
Packet is AAR format.
Packetization module 402 is compiled, for the source code of host's engineering and dependence packet to be compiled packing to obtain
The installation kit of host's engineering, will not include the source code of each plug-in unit engineering of the common code and public resource into
Row compiling is packaged to obtain the installation kit of each plug-in unit engineering.It exports the code of plug-in unit engineering itself and resource to form standard
APK installation kit, common code and public resource only rely on without being bundled in the APK installation kit of plug-in unit engineering, it is subsequent
By constructing the running environment of plug-in unit engineering come the APK installation kit of load operating plug-in unit engineering in host's engineering.
Environment construction module 403, for constructed in the installation kit of host's engineering load operating environment to load and
Run the installation kit of each plug-in unit engineering.After each business module is implemented plug-in unit, the APK installation kit of plug-in unit engineering is simultaneously
It is not directly mounted on mobile phone, system can not be transferred to directly to handle, the APK installation kit itself of host program is needed to construct
The load operating environment of the APK installation kit of one plug-in unit engineering, loaded and run by this environment each plug-in unit engineering resource and
Code.Hook technical construction load operating environment is used in embodiment to load the resource and code of each plug-in unit engineering.
In addition, the Android plug-in unit of the embodiment of the present invention melts the device of hair further include: resource identification setup module and packet
Identify replacement module (the two modules are not shown in the figure), resource identification setup module be used for for host's engineering resource,
Different resource identifications, the resource setting of each plug-in unit engineering is arranged in the resource of the public resource and each plug-in unit engineering
Rule are as follows: the packet mark of the resource of each plug-in unit engineering is different from the resource of host's engineering, the packet mark of public resource
And the packet mark between each plug-in unit engineering is all different；Packet mark replacement module, for being by each plug-in unit engineering
The packet mark of system default replaces with the packet mark of setting.
From the above, it can be seen that public resource and common code are compiled into host's work in the independent form for relying on packet
Journey relies on this to be supplied to the use of plug-in unit engineering, by plug-in unit engineering code after the extraction of original engineering and relies on packet exploitation, drop
Undershoot part enforcement difficulty makes the exploitation of engineering centralization that can smoothly switch plug-in type development mode；The embodiment of the present invention
