The improvement that the present invention makes, mainly proposes based on the Dalvik virtual machine of Android, certainly, if framework is similar to the mechanism of Dalvik in other operating system, also the present invention can be promoted it in theory.In order to understand the present invention, please first understand the installation file structure of the following android system disclosed:

In android system, each application program installation kit is APK file, i.e. the abbreviation of AndroidApplication Package File, its essence is the file of zip form, carries out decompression can obtain following file structure to it:

Table 1 APK file structure

Usually, during exploitation Android application program, the four large assemblies that provide with Android for unit is developed, this four large assembly is Activity, Service, Receiver, Provider respectively, the code that four large assemblies are relevant can be integrated in classes.dex file, but this four large log-on message needed for assembly and rights request message then can be declared in Androidmanifest.xml file.Include an AndroidManifest.xml file in each apk file, it records the global configuration information of installation kit, is typical configuration file.In this configuration file, except information such as bag name package name, start context versionCode, version number versionName, also comprise the system components such as activity, service, receiver, Provider of application program registration, the log-on message of each large assembly is stated in this configuration file, when mounted, be supplied to application program to system registry, specifically read this configuration file to complete registration by the PackageManagerService of system.Well-known, under normal circumstances, the movable component (Activity) only stated in Androidmanifest.xml by routine call, just can be able to be opened, thus show events interface, so that realize man-machine interaction in terminal.And movable component dispatching party rule provided by the invention can overcome this inadequate natural endowment.

Movable component dispatching method of the present invention as disclosed in the system of fig. 1, can be implemented in the host's functional module used as master routine, it specifically comprises the steps:

S11, be supplied to position, system pre-registration multiple movable component hole.

As previously mentioned, under regular situation, movable component needs to state in as the Androidmanifest.xml file in host's functional module of master routine, so that when system is installed, registers relevant movable component with the log-on message in this statement.And the present invention arranges multiple movable component log-on message for reserved object in the Androidmanifest.xml configuration file of host's functional module, but the true content of the movable component pointed by these log-on messages is not determined, therefore, in the present invention, visually these configuration files have been reserved the movable component of log-on message, and this configuration file be supplied to after system is installed formed the virtual unit of movable component be referred to as movable component hole position.Specifically, the log-on message of multiple movable component is stated in advance, when master routine is installed, to be registered according to these log-on messages by PMS in the Androidmanifest.xml file of master routine, by AMS for it sets up process entrance, thus the position, movable component hole described in being formed.

Consider in the present invention, by the different attribute according to movable component, the attributes such as such as launchMode, taskAffinity, theme carry out Classification Management to movable component, therefore, the bag name used in described log-on message, different characteristic characters can be used in the suffix of bag name for characterizing dissimilar position, hole, is also refer to the different process spaces, is beneficial to identify.The such as following example quoted:

Wherein the shape of the Bao Mingzhong of movable component is as the just characteristic character of the X in ActivityX, which process space characteristic character X deputy activity assembly should run in, " N1 " given by upper example is comparatively special, it is the characteristic character for retaining, representing host process (UI process), can be then refer to the dissimilar movable component provided according to aforementioned various movable component attribute after " N1 ".The suffix ActivityN1ST0 of the bag name given by upper example can characterize position, this hole and run in system default (UI) process, and use the SingleTask of follow-up announcement to show, Activity0ST0 then represents and runs in loader0 process, and uses SingleTask table.About the relation between these different characteristic characters and the dissimilar table that corresponds, will disclose follow-up.

Need preferential it is mentioned that, scheduler object of the present invention, also namely movable component to be loaded normally provides with the form of pin function module, such as, be supplied to user with the form of a compressed package and carry out downloading and loaded by technological means of the present invention.This pin function module is except the function code comprising movable component, its intrinsic log-on message can also be expressed by built-in configuration filename a such as Androidmanifest.xml, the log-on message of the configuration file of plug-in unit alleged here then can be write flexibly even without restrictions, such as, can write according to following form:

That is, the log-on message of pin function module self can not determine which process it runs in, but by method of the present invention decide above-mentioned AntitheftEntryActivity finally can drop in ActivityN1ST0, ActivityN1ST1 (one process) Activity0ST0, Activity1ST0 which hole position in.

Table is ranked in the hole that S12, structure comprise the characteristic information of position, described multiple movable component hole.

Build the process that table is ranked in hole, will the utilization to Application class be related to, therefore introduce Application class in advance.

Application with Activity, Service are the same is a system component of Android framework, and when Android program starts, system can create an Application object, is used for some information of storage system.Android system automatically can for creating the object of an Application class and only creating one, so Application can be described as a class of single example (singleton) pattern when each program is run.Appointment Application is not needed during usual use, system can create such automatically for it, if need to create own Application, only need create a Similar integral Application and carry out registering (only need to increase name attribute to application label, and add the name of the Application of oneself) in application label in AndroidManifest.xml file.

When starting Application, system can create PID, i.e. a process ID, and all Activity can run in this process.If so initialization global variable when Application creates, all Activity of same application can get the value of these global variables, in other words, if change the value of these global variables in some Activity, so will change in other Activity intermediate values of same application.The life cycle of Application object is the longest in whole program, and its life cycle just equals the life cycle of this program.Because it is single example of the overall situation, so the object obtained in different Activity, Service is all same object.So can be undertaken by Application, as: the operations such as data transmission, data sharing and data buffer storage.Realize the global variable of application-level by inheriting Application class, this global variable method relative quiescent class is more secure, just can be released until all Activity of application are all fallen by destory.

In like manner, the launchMode attribute that the Activity please understanding Android further provides.

Whether launchMode plays important role in the process of multiple Activity redirect, and it can determine whether generate new Activity example, whether reuse already present Activity example, a task stack public with other Activity examples.Here simply introduce the concept of task, task is an object with stack architexture, and a task can manage multiple Activity, starts an application, the task that also just establishment one is corresponding with it.

The total following four kinds of launchMode of Activity mono-, several modes and being described below:

1.standard

Standard pattern is the start-up mode of acquiescence, and need not configure android:launchMode attribute for <activity>, can certainly designated value be standard.No matter standard start-up mode, have and do not have already present example, all generates new example.

2.singleTop

SingleTop start-up mode, if find that there is corresponding Activity example to be sitting at stack top, then reuses, the example that regeneration is not new.

3.singleTask

SingleTask pattern, if find that there is corresponding Activity example, then makes other Activity examples on this Activity example completely pop, makes this Activity example become stack top object, before being shown to curtain

4.singleInstance

This start-up mode is more special, because it can enable a new stack architexture, is positioned over by Acitvity in this new stack architexture, and ensures that no longer including other Activity examples enters.

The android:launchMode attribute that can configure <activity> at AndroidManifest.xml is one of above four kinds.

In view of the above characteristic of Application and launchMode, the present invention, by reconstruct Application.onCreate method, writing the code command for adding position, each movable component hole characteristic information wherein, realizing the structure that table is ranked in described hole.

The following table provided, namely hole rank table, it is in fact achieve the index to concrete list that table is ranked in this hole, shape as:

In code above, String field is character string, and represent that Activity cheats position, the hole name of position, ActivityState is then status information.Table is ranked as can be seen from this hole, although it can be the characteristic information establishing mapping relations directly comprising position, each movable component hole that table is ranked in this hole, but in the embodiment that this table provides, be then set up management to position, movable component hole characteristic information by comprising a summary table and multiple type list.Each table given by above-mentioned code, from top to bottom, is followed successively by:

MStates: summary table, as the term suggests all Activity will be stored in this table, using as the use gathered.

MStatesST: represent that launchMode is the table of SingleTask, its log-on message can be expressed in the following manner:

MStatesTA: represent that taskAffinity is the table of designated value, the ownership of taskAffinity attribute representation Activity, namely Activity should in which Task, the absorption relation of Activity and Task.Generally in same application, the Activity of startup is in same Task, and they spend oneself life cycle in this Task.If an Activity does not have the explicit taskAffinity indicating this Activity, so its this attribute just equals the taskAffinity that Application indicates, if Application does not also indicate, so the value of this taskAffinity just equals bag name.And Task also has the affinity attribute of oneself, its value equals the value of the taskAffinity of its root Activity.At the beginning, the Activity of establishment can in the Task creating it, and major part has spent its whole life all here.But having certain situation, the Activity of establishment can be assigned with in other Task and go, and has even, originally in a Task, has occurred transfer afterwards.Therefore, be necessary to be according to internus table with taskAffinity.The log-on message of this table can be expressed in the following manner:

MStatesNR: expression launchMode is the table of Standard (default value), and its log-on message can be expressed in the following manner:

MStatesF: represent that theme attribute is the table of FullScreen (full screen), its log-on message can be expressed in the following manner:

MStatesT: represent that theme attribute is the table of Translucent (transparent background), its log-on message can be expressed in the following manner:

MStatesTF: represent that theme attribute is the table of Translucent.FullScreen (full frame and transparent), its log-on message can be expressed in the following manner:

MStatesD: represent that theme is the table of Dialog, its log-on message can be expressed in the following manner:

MStatesSID: represent that launchMode is SingleInstance and Theme is the table of Dialog, its log-on message can be expressed in the following manner:

More than made introductions all round the summary table and type list of cheating and ranking in table, be mainly used in illustrating that an embodiment of table is ranked in hole to reader, those skilled in the art are to be understood that, the realization of table is ranked in hole, as long as establish the management of the characteristic information to position, described movable component hole, no matter its specific implementation form how, and also no matter it directly or indirectly contains described characteristic information, all can apply in a flexible way according to Spirit Essence of the present invention for those skilled in the art.

As previously mentioned, on the basis knowing above-mentioned implementation, by the code of reconstruct Application.onCreate method, the foundation of described hole being ranked to table can be realized.Below provide example code shape as:

By the enforcement of shape example code described above, finally, position, each movable component hole is created in mStates summary table and other type list respectively, and wherein Containers represents " mContainerActivity " object of Activity.

By above-mentioned mode, just set up the index relative that each sublist included by table is ranked in hole, form a data framework thus.Then, for position, each hole, need to understand it and be recorded hole and rank table, be specifically stored into the structure of the characteristic information in each corresponding form.The characteristic information of position, each hole, mainly by timestamp when there is position, the hole name of mapping relations, using state, movable component title to be loaded (i.e. the title of pin function module), amendment using state, form data item such as the weak references of movable component, if desired, the increase and decrease of modified also can be carried out to these critical items.These characteristic information items, are summarized as follows:

(1) container: position, the hole name of position, movable component hole correspondence;

(2) state: position, movable component hole using state, has following several mark:

Private static final int STATE_NONE=0//expression non-working condition

Private static final int STATE_REGISTERED=1//represent distribution state

Private static final int STATE_LOADED=2//represent stress state

Private static final int STATE_CREATED=3//represent creation state

Private static final int STATE_RECYCLED=4//expression reclaims state

(3) mCN: corresponding target plug-in functional module and title thereof;

(4) timestamp: timestamp during amendment using state;

(5) ref: retain the weak reference to movable component.

Above characteristic information is can assignment as required in several cases.Such as mCN field can carry out assignment at allocated phase, and state situation is special, illustrates respectively below:

When 1, entering master routine, can in Application.attachBaseContext, the above-mentioned information of initialize process, is set to STATE_NONE by the state of position, each movable component hole;

2, when the movable component to be loaded in pin function module is assigned with position, hole, state state can be set to STATE_REGISTERED;

3, after movable component to be loaded is loaded by Classloader classLoader, position, movable component hole is returned and after being loaded, state state can be set to STATE_LOADED;

4, when the onCreate method of movable component to be loaded is called, the state state of position, corresponding target hole can be set to STATE_CREATED;

5, when movable component to be loaded is released (call Activity.onDestroy, or position, hole being full, during distribution), then state state can be set to STATE_RECYCLED.

Above, disclosed in detail and realize the example that table is ranked in described hole, those skilled in the art, according to the above-mentioned exemplary illustration for this step, are enough to specific implementation and the variants thereof of knowing this step.Through the process of this step, rank table by constructing the required for the present invention hole including position, multiple movable component hole characteristic information.It is also realize movable component process space distribution method of the present invention and the necessary preparation of device that table is ranked in this hole.

The table goal activities assembly hole position suitable for movable component to be loaded distributes is ranked in step S13, utilization hole.

In order to implement this step, the present invention and then disclose a kind of movable component process space distribution method, uses this method to rank table to described hole and is used, and be finally that movable component to be loaded in pin function module distributes and cheats position.The method realizes primarily of following step S21, S22, S23, is described in detail to each step below in conjunction with Fig. 2:

Step S21, be received as movable component allocation activities assembly to be loaded hole position request.

In like manner, because movable component process space distribution method of the present invention is as a part for movable component dispatching method of the present invention, be programmed in the host's functional module be implemented in as master routine, thus, it mainly utilizes process thinking to be programmed to functional module, external receiving parameter to receive request, and feeds back corresponding result to requesting party.Based on this principle, by this step, when master routine needs the movable component to be loaded of loading of plug-in functional module, by the functional module that the relevant information being transmitted movable component to be loaded by master routine or its component part constructs to this distribution method, to carry out follow-up process by this distribution method to it.

It is to be noted, this distribution method treats the position, movable component hole will carrying out distributing, position, movable component hole namely constructed by dispatching method of the present invention, therefore, namely position, these movable components hole is state log-on message and the process space formed to system registry in Androidmanifest.xml file as host's functional module of master routine.The more excellent part of this distribution method is, in some processes, can manage the movable component to be loaded of multiple pin function module.

The preference policy that step S22, utilization are preset, ranks position, goal activities assembly hole preferably suitable for movable component to be loaded table from hole.

Table is ranked in described hole, and table is ranked in the hole also namely constructed by abovementioned steps S12, for storing the characteristic information of the position, movable component hole of multiple pre-registration.Due in foregoing example, hole is ranked table and is included summary table and all kinds table, summary table wherein includes the characteristic information of position, all movable components hole, type list wherein only stores the characteristic information belonging to the position, movable component hole with identical type feature, therefore, when implementing the preference policy preset, first can retrieve type list, just retrieving further in summary table when type list does not find the movable component of sweet acid.And when implementing retrieval, table design concept is ranked in the hole according to aforementioned announcement, correspondingly, also should carry out differentiating to determine specifically corresponding type list according to launchMode, taskAffinity and/or theme attribute of movable component.

This step is preferred to position, described goal activities assembly hole, and mainly foundation using state is wherein according to carrying out.

Below disclose the flow process using described preference policy:

This dispatching method stores all ActivityInfo objects in advance in PackageInfo, so can directly use these information here.In this sub-step, differentiated and the type list belonging to the movable component to be loaded of request dispatching by attributes such as launchMode, taskAffinity, theme, start to retrieve type list.Code sample is as follows:

Then, from corresponding type list, determine suitable position, goal activities assembly hole, in code above, the signature of alloc method is:

Wherein, ai represents ActivityInfo, and map is exactly that table is ranked in the hole of specifying, plugin and activity represents pin function module title and movable component title to be loaded thereof respectively.

Adopt following strategy to carry out preferably, carrying out according to the order of sequence, as long as any rule is met below, directly can return results, need not subsequent step be carried out:

(1) preferred for SingleTask and SingleInstance type preferably searches one with the example crossed.Consult following code:

As previously mentioned, SingleTask and SingleInstance is more special, and these two kinds of modular systems require that Activity example can only have portion, therefore must look for an example opened.And other LaunchMode does not have this to limit, Multi-instance can be used.

Such as, opened before the BarcodeActivity of Quick Response Code plug-in unit, if so still will open, then here can make a decision: first its using state must be STATE_CREATED, and target plug-in must be Quick Response Code, and Activity must be corresponding title as BarcodeActivity, and also have Activity object, so could directly return this result.Otherwise arbitrary condition does not meet, all next step will be carried out.

(2) adopt position, unworn hole, consult following code:

If by detecting, this position, hole does not use, then directly use, return results, and does not carry out subsequent step.

(3) adopt and used but stopped, noting not distinguishing launchMode here, wherein SI and ST both of these case is in step process mistake before.Consult code:

In like manner, if found, return results, do not carry out subsequent step.

(4) position, hole be translated the earliest is found.Consult code as follows:

In like manner, if found, return results, do not carry out subsequent step.

(5) with (4) article of strategy unlike, even be assigned with state here, but not used position, hole (this situation is fewer, and normally Activity is once creating release or creating unsuccessfully etc.), will reclaim wherein the earliest that here.Consult following code:

In like manner, if found, return results, do not carry out subsequent step.

(6), when not finding suitable position, hole at exhaustive above-mentioned various strategy, that load the earliest can only be reclaimed.Consult following code:

If found, return results, do not carry out subsequent step.

(7) in like manner, when above various strategy is searched all failed, just with last strategy, the earliest the Activity run can only be reclaimed.Consult following code:

Through the effect of above-mentioned preference policy, obtain position, unique goal activities assembly hole the most at last, complete position, hole and distribute.

Step 23, to be obtained position, this target hole by previous step after, using state state in the characteristic information of this position, hole can be set to STATE_REGISTERED, obtain position, the hole name Activity.mContainer of this position, hole simultaneously, return to requesting party as a result.

The movable component process space distribution method provided by the invention described above, can be optimized a goal activities assembly suitable with movable component to be loaded and cheat position.After obtaining position, this target hole, just on the basis of the relevant information returned, subsequent treatment can be done by dispatching method of the present invention.

Step S14, this movable component to be loaded is loaded in the process space of target hole corresponding to position and runs.

Based on the result of implementation of abovementioned steps, movable component to be loaded to be loaded in the corresponding process space according to following concrete steps and to run by the present invention then:

Step 141, to rank table the position, goal activities assembly hole obtaining and be assigned with from described hole.

As previously mentioned, in step 13, finally can determine position, unique target hole by distribution method provided by the invention, and return the information of position, this target hole.These information spinners will comprise position, hole title, after determining position, hole title, namely load movable component to be loaded by Classloader.

Due in step 13, the using state state target having been cheated position is labeled as STATE_REGISTERED and returns position, hole name, therefore, in this sub-step, only need, with this mark, table (specific to certain type list) is ranked to hole and search.With reference to following code:

The Classloader of step 142, operation reconstruct is the movable component determination class object to be loaded being assigned with position, hole.

Classloader alleged by the present invention is realized by the ClassLoader of reconfiguration system.The object of reconstruct Classloader, is wish that changing system when master routine starts generates the method for new class, thus guarantees correctly to load movable component to be loaded, makes it run on target and cheats the process space that position refers to.

In a kind of prior art, generate DexClassLoader, call realize when plug-in unit starts usually through oneself, its shortcoming is apparent, calls very not directly perceived exactly, must obtain the designation method first calling DexClassLoader and realize.As follows:

Existing: XXX my=mDexClassLoader.findClass (XXX) .newInstance ();

This work: XXX my=new XXX ();

In another kind of prior art, realized by the contextClassLoader mode of replacing Thread.The maximum problem of this mode does not support the scenes such as Activity, Service, AIDL, and these regional system acquiescences can use the ClassLoader of PackageInfo, but not Thread, use scenes is subject to serious restriction.

The ClassLoader of reconstruct of the present invention will realize the replacement completely to the Classloader of system, particular by the ClassLoader replacing PackageInfo, guarantee to replace without dead angle, not only Thread can use, connect the assemblies such as Activity, Service and can use self-defining ClassLoader to realize loading, its application scenarios is more extensive, and invoked procedure is very directly perceived, caller, without the need to considering any fallback relationship, directly uses.

Realize the method for self defined class loader, can carry out with reference to following steps:

First, during each process initiation, all can call Application object, this object also can be self-defined by the mode inherited.System can call Application.attachBaseContext method at first, therefore, and the suitable ClassLoader importing reconstruct herein.

Then, PackageInfo is obtained.In this course, realize according to following sub-step:

(1) first need to obtain ContextWrapper object.Also namely: reflection obtains the mBase field in Application object.The object obtained keeps for subsequent use.

(2) mPackageInfo is obtained.

The mBase object obtained, different android system can represent different types, is then ContextImpl if Android 2.1 be ApplicationContext, Android 2.2, Android 2.3 and above be then AppContextImpl.But no matter which is, has common feature, namely have one to be named as " mPackageInfo " field, directly reflection obtains the mPackageInfo field in mBase object, can obtain PackageInfo object.

Above two useable code illustrate:

Then, self-defining ClassLoader object is generated.

As long as self-defining Similar integral ClassLoader or its subclass object, just mean and complete self-defining operation.On this basis, it will be understood by those skilled in the art that and can do a large amount of work relevant with pin function module.

Except self-defined, also must override all methods in ClassLoader, each method finally should point to before ClassLoader, the successful reconstruct of ClassLoader can be guaranteed thus and normal to use.As follows with the example code not adding any custom feature:

As mentioned above, mBase be exactly before ClassLoader.After processing customized event, if necessary, then the corresponding method calling mBase is needed.

Finally, the mClassLoader of PackageInfo is replaced

The mPackageInfo object retained before is taken out, the self-defined ClassLoader object that mClassLoader field is above-mentioned generation is set by reflection.

For code, following code sample can be inserted at " ... " clipped of the example code obtaining mPackageInfo:

Thus, the process of the ClassLoader of replacement system terminates, and completes the self-defined reconstruct of ClassLoader.ClassLoader due to system has been replaced by self-defining ClassLoader, according to its use scenes and character, generally speaking, obtain category information as long as have, generate new class, call the situations such as Native method, be just bound to be loaded by this self-defined ClassLoader.

Therefore, by the self-defined ClassLoader of above-mentioned realization, the DexClassLoader of succession, its findClass method is also reconstructed, and is embodied as described movable component to be loaded and searches object in findClass.Once have found the title of position, target hole object, next only need the ClassLoader of current pin function module to get, then perform invoke method, the Class object of this plug-in unit can be obtained.

Step S143, operating instruction are opened position, target hole and are run to make movable component to be loaded load in the process space.

Specifically, because the process space is set, and the class object of movable component to be loaded also finds, and connects down and only needs to splice both.First by the process space of position, ComponentName (inherent function of system Intent) object transfer target hole, utilize this object formation Intent, then with this Intent of context.startActivity method call, position, target hole can be opened, thus movable component to be loaded is loaded in the set process space run.

In other embodiments of the invention, carry out the process space run for described movable component to be loaded, can through a preferred step, to provide a set and preferred process space before position, aforementioned distribution target hole.

Visible, movable component dispatching method provided by the invention, can realize the flexible dispatching treating loading activity assembly, and movable component to be loaded can be added in the mode of pin function module flexibly independent of outside host's functional module of master routine.

Further, movable component dispatching method example of the present invention can be changed into program, be attached in the host's functional module used as master routine, and a kind of control method is provided, when master routine runs, implement this dispatching method, scheduling is implemented to the movable component that described pin function module comprises, this movable component is run in the process space created by host's functional module.The upgrading of this master routine will become more simple and easy and economize flow, and in theory only otherwise relate to the framework amendment of master routine, master routine just can never be upgraded.
