Illustrate to body method provided by the present invention.
As shown in Fig. 2, for a kind of specific method flow chart for loading plug-in unit provided in an embodiment of the present invention, this method includes
Step S201 to S206.
Firstly, executing step S201 obtains the installation kit archive information of plug-in unit when plug-in unit is triggered
PackageArchiveInfo。
Wherein, plug-in unit is a module of main program.It usually may include more in the application program based on developing plug
A module, wherein each module can be realized by a plug-in unit.Currently, due to the liter of the application program under Android
Grade is inconvenient, and the plug-in unit of application program has become a kind of trend.
For example, may include the functions such as rubbish cleaning, self-triggered program management, wooden horse scanning in a optimization software,
Wherein, each function can individually develop into a module, a plug-in unit as optimization software.When optimization software needs to increase
When new function " hardware testing ", a plug-in unit only need to be write again and is discharged under main program, without updating entire application program,
Developer is also not required to carry out packing compiling to entire application program again again.
Under normal conditions, plug-in unit is an apk file, and user after downloading, can be directly released into the specified mesh of main program
In record, that is, complete the installation of plug-in unit.
It should be noted that in order to enable plug-in unit can be loaded, inside the apk of plug-in unit should by developer to it at least
An entrance (Entry) is provided, for completing the loading procedure of plug-in unit.
It, in the present embodiment, can be in the following way in order to realize the entrance of plug-in unit:
The primary ClassLoader object of system is replaced using ClassLoader object customized in main program.
The particular load mode of the class or resource to application program, example may be implemented in customized ClassLoader
Such as, when loading the activity component of plug-in unit, the context of re-direction applications program is the context of plug-in unit, with realization pair
The complete load of plug-in unit.
Specifically, primary for using in main program customized ClassLoader object to replace system
The method of ClassLoader object may include:
When the process initiation of application program, obtaining operating system is the PackageInfo object that application program is established, and is obtained
The mClassLoader field in PackageInfo object is taken, the address in mClassLoader field is modified, is directed toward it certainly
The ClassLoader object address of definition, so as to complete customized ClassLoader object to primary
The replacement of ClassLoader allows to through customized ClassLoader object loading application programs.
Triggering for plug-in unit usually may include two kinds of situations:
One is the active of user click, when user needs the corresponding function of plug-in unit, the plug-in unit is clicked to start.
Another kind is when main program starting, and triggering plug-in unit loads automatically.For example, certain optimization functions, are opened in main program
Plug-in component operation is needed when dynamic.
In this step S201, the installation kit archive information PackageArchiveInfo for obtaining plug-in unit can be by such as lower section
Method:
Firstly, obtaining the object of the PackageManager of plug-in unit；
Then, mContext.getPackageManager () interface is recalled to realize that the installation kit for obtaining plug-in unit achieves
Information.
For example, being pm by PackageManager object definition in the present embodiment, then it can be realized and be obtained by following code
Take the PackageManager object of plug-in unit:
In above-mentioned code, mPath is the path of plug-in unit, GET_ACTIVITIES, GET_SERVICES, GET_
PROVIDERS, GET_META_DATA respectively indicate the letter for obtaining Activity, Service, Provider of apk of plug-in unit
Breath and Android Manifest in META_DATA information.
Wherein, the installation kit archive information PackageArchiveInfo of plug-in unit be include apk Activity,
The information and the META_DATA information in Android Manifest of Service, Provider.
Also, installation kit archive information of the four kinds of information as above as plug-in unit in the present embodiment, is only obtained, can be mentioned
The loading velocity of high plug-in unit, improving performance.
It should be noted that may include multiple plug-in units under a main program.For example, under security guard's software, it can
To there is the plug-in unit of the functions such as sweep-drug, cleaning, encryption, user can select download plug-in according to demand.It is developed based on Plugin Mechanism
Program, carry out plug-in unit iteration when, update can also be downloaded just for single plug-in unit.
In the present embodiment, it can choose and plug-in unit be downloaded or updated by cloud server, method can be such that
Step A, before plug-in unit is triggered or triggers, whether detection plug-in unit be can be used, if available, step S202 be executed, if not
It can use, execute step B；
Wherein, unavailable includes not downloading or the version of plug-in unit is too low.
Step B sends the request for obtaining plug-in unit list to server；
Wherein, server preserves the plug-in unit list of current main program, in the list record have plug-in unit plugin name,
Plug-in version, the digital digest value of plug-in unit and the download address of plug-in unit.
As shown in table 1 below, the as example of plug-in unit list:
| Plug-in unit name | Plug-in version | Plug-in unit MD5 | Plug-in unit URL |
| Plug-in unit A | 1 | A111 | http://a.360.cn/a.apk |
| Plug-in unit A | 2 | A222 | http://a.360.cn/a2.apk |
| Plug-in unit B | 1 | B111 | http://a.360.cn/b.apk |
Table 1
Wherein, MD5 (Message Digest Algorithm 5rd, Message Digest Algorithm 5) value is digital digest
One kind of value.
Step C receives the plug-in unit list that server is sent；
Step D downloads the plug-in unit of new version according to the download address of the plug-in unit in plug-in unit list；
Whether step E, the digital digest and the digital digest in plug-in unit list for verifying the plug-in unit of the new version of downloading meet,
If it is, plug-in download or update are completed, if it is not, re-downloading.
After getting the installation kit archive information of plug-in unit, step S202 is executed, it will be default under installation kit archive information
Variable is revised as preset path.
It should be noted that realizing the load to plug-in resource in the present embodiment, the normal initial of plug-in unit is changed
Change process (such as context of replacement main program), therefore, needs to modify in this step default under installation kit archive information
Variable, to prevent the program throw exception in the loading procedure of plug-in unit.
In the present embodiment, design variables include: sourceDir and publicSourceDir.
Preset path is the path mPath of plug-in unit.
For example, the modification to design variables can be realized by following code:
MPackageInfo.applicationInfo.sourceDir=mPath；
MPackageInfo.applicationInfo.publicSourceDir=mPath；
After modifying design variables, i.e., executable step S203 obtains the resource of plug-in unit.
In this step S203, the resource of plug-in unit can be obtained in the following way:
By call PackageManager object (namely customized pm in step S201, it is complete in step s 201
At obtain operate) in getResourcesForApplication method, to obtain the Resources object of the plug-in unit, then
Pass through the resource of Resources object acquisition plug-in unit.
It wherein, include the related all resource informations of the plug-in unit in Resources object.
For example, can be realized by following code:
Wherein, mPkgResources is the resource of plug-in unit.
After acquiring the resource of plug-in unit, step S204 is executed, creates DexClassLoader class for plug-in unit.
Wherein, a plug-in unit is usually made of dex (binary code under Android) file and resource, if completing to insert
The load of part then needs to load the dex file and resource of plug-in unit simultaneously.In android system, load for dex file,
It is completed by DexClassLoader class.DexClassLoader also becomes class loaders.
In order to enable DexClassLoader can correctly load the dex file of plug-in unit, need newly-built
The path that the dex file of plug-in unit is stored in DexClassLoader, transmits plug-in unit by newly-built DexClassLoader
The path of dex file.
For example, can be realized by following code:
String out=mContext.getDir (DIR, 0) .getPath ()；
MClassLoader=new DexClassLoader (mPath, out, null, parent)；
Wherein, parent indicates that newly-built DexClassLoader is parent loader, has more than is needed in order to avoid occurring adjusting
The problem of android system class.
After newly-built DexClassLoader, that is, guarantee to load the dex file of plug-in unit.In the present embodiment,
In order to the resource of normal load plug-in unit, also need to execute step S205, i.e., the context of newly-built plug-in unit oneself, and replace
The context of main program.
Wherein, context is the unique identifier of application program in android system, is equivalent in windows system
Handle all need to complete by context when needing to call dex file, the resource etc. of application program.In normal condition
Under, when an application program launching, operating system can be one context of the application initialization, and without being slotting
Part distributes context, and therefore, in existing android system, the load for plug-in unit is always a difficult point.
Therefore, in the present invention, need to create a context for plug-in unit to be loaded, in order to be different from main program
The context of context, plug-in unit can be defined as PluginContext.
For example, creating PluginContext for plug-in unit can be realized by following code:
Wherein, the PluginContext of plug-in unit has to be inherited from ContextThemeWrapper, it is Context
Encapsulate class.
After establishing the PluginContext of plug-in unit, for the Context for distributing its replacement system main program, also
Below step need to be executed:
Override method function relevant to plug-in unit load.
In the present embodiment, method function relevant to plug-in unit load mainly includes following three:
GetClassLoader, getResources and getAssets.
Wherein, getClassLoader is used for loading classes, such as DexClassLoader；
GetResources and getAssets is used to load the resource of plug-in unit.
It how is exemplified below to these three method letters of getClassLoader, getResources and getAssets
Number is override:
(1)getClassLoader
Wherein, as long as being related to the place of Context calling, the side Context.getClassLoader all can preferentially be used
Method can call this method when application program launching, since we have override this method, being returned is us in step
The DexClassLoader created in rapid S204 completes adding to the class of plug-in unit by the DexClassLoader that we create
It carries.
(2)getResources
Wherein, the place for obtaining resource is generally involved, getResources method function can be all called, after overriding
In getResources method function, when the function is called, i.e., the Resources object of plug-in unit can be returned to, to complete
Load to the resource of plug-in unit.
(3)getAssets
Wherein, getAssets is also the resource for obtaining plug-in unit, when loading the part resource of plug-in unit, be will use
GetAssets method function.When the function is called, i.e., the Assets object of plug-in unit can be returned to, to complete to plug-in unit
The load of resource.
After rewriteeing above three method function, the load of dex file and resource for plug-in unit can all realize replacement, can
Plug-in unit under perfect load main program.
Finally, step S206 is executed, according to the resource and dex file of the context load plug-in unit after being replaced.
It should be noted that generally there is an entrance (Entry) when program starts, after the triggering in order to realize plug-in unit
The load of resource can be carried out, we can realize an Entry in plug-in unit.In all entrances, Entry is to be adjusted earliest
, it is similar to the Dalvik.main of Android, is the place of entire plug-in unit most entrance.
Such as following code, the entrance of as one plug-in unit:
String className=PACKAGE_PREFIX+ " _ "+mName+ " _ "+CLASS_NAME
Class<?>C=mClassLoader.loadClass (className)；
McreateMethod=c.getDeclareMethod (Factory.METHOD_NAME, Factory_METHOD_
PARAMS)；
Mplugin=(IPlugin) mCreateMethod.invoke (null, mPkgContext, manager)；
We can first obtain the entry method of Entry, be in the present embodiment Create, then call the party by reflection
Method, mPkgContext and manager (cache interface is shown in " plug-in unit scheme " series) etc. are passed to plug-in unit entrance can (as above
It states shown in code).
In addition, we use mClassLoader, this is the ClassLoader of plug-in unit, that is to say, that
Entry.create is present in plug-in unit, rather than other places.This is arrived, entire loading procedure terminates, and plug-in unit can start to make
With.
It is illustrated Entry in order to clearer, the example that an Entry class is shown below is as follows:
Wherein, " package com.qihoo360.plugin.antitheft " indicates the packet of the packet where the Entry class
Entitled " com.qihoo360.plugin.antitheft "；
" public class Entry " indicates that the class of newly-built class is entitled " Entry "；
" public static final IBinder create " indicates that the earliest entrance of entire plug-in unit is " cerate "
Method, and parameter " ClassLoader of plug-in unit Context, plug-in unit IBinder and main program " is delivered wherein；
" return new Plugin (context, cl) " is indicated to return to an interface used by main program, be may is that
IBinder may is that IPlugin or other, but howsoever, which is all finally main program to be returned, by main program
It is scheduled.
The embodiment of the invention provides a kind of methods for loading plug-in unit.When plug-in unit is triggered, the resource of plug-in unit is obtained, newly
