Specific embodiment
The present invention is described in further detail with reference to the accompanying drawings and examples.It is understood that this place is retouchedThe specific embodiment that states is used only for explaining the present invention, rather than limitation of the invention.It also should be noted that, in order to justPart related to the present invention rather than entire infrastructure is illustrate only in description, accompanying drawing.
Fig. 1 is the flow chart of the internal memory control method of terminal device provided in an embodiment of the present invention, and the present embodiment is applicableIn the situation is controlled by terminal device internal memory, the method can be executed by terminal device such as smart mobile phone, panel computer,Specifically include following steps：
The main memory usage for applying corresponding application of attending to anything else in step 101, acquisition terminal device.
Multiple application software are installed in terminal device, such as QQ, wechat, microblogging etc., user can be executed by these softwaresCorresponding function.In this programme, installing terminal equipment has main application and application of attending to anything else.In this programme, main application is corresponding with whichApplication attend to anything else as the application that opens in set of applications, its implementation can have many kinds, and the present embodiment is not specifically limited more.For example, the application of different editions can be respectively mounted, using a kind of version as main application, using other versions as application of attending to anything else, itsIn, installation kit (APK) file of application can be changed by decompiling, then amended APK file is installed to realize difference is installedThe same money application of version；And for example, open assistant's software the third party that application simulation user's space and Dynamic loading technique can be passed through moreTo realize；For another example, can be realized by changing system mechanism.
Preferably, open set of applications in the present embodiment to realize based on multi-user's mechanism, wherein multi-user's mechanism is concrete moreMay include multi-user's mechanism that the operating system in intelligent terminal is supported, such as multi-user's mechanism of Android (Android) systemAnd multi-user's mechanism of mobile phone window (Windows Phone, WP) operating system etc..
Wherein, open set of applications to realize based on multi-user's mechanism more, now illustrated as follows：
Specifically, open set of applications to realize may include following content based on multi-user's mechanism more：Main application is installed on masterUnder user, application of attending to anything else is installed on under user, comprising the access port for being used for operating application of attending to anything else in primary user.
In one embodiment, multi-user's realization mechanism of the application includes following logic：
1. multi-user management
A) system default has a primary user, and primary user can create other multiple new user (from users), it is possible toDelete and manage them；
B) domestic consumer (non-master user) and Guest User, can be collectively referred to as from user；
C) acquiescence primary user id (identity, Identification) is 0, and other Add User id from the beginning of 10, byIndividual increase；
When d) switching user, a series of changing interface such as desktop can be reloaded；
E) primary user can limit whether other users can take the authority such as phone and transmitting-receiving note.
For multi-user management, can by primary user to being managed from user, including the establishment from user, deletion andPriority assignation etc., ID are arranged from the beginning of primary user, are increased newly from when switching between ID laminated structure, each user, and it is right to reloadAnswer a series of interfaces such as desktop of user.
2. multi-user's peace loading, unloading application
A) application of default installation, can be installed to all users that oneself creates, all visible application on other user's desktopsIcon；
B) application that is installed by file management in primary user, will not be installed to other users, on other user's desktopsInvisible application icon；
C) system may specify userid (User Identity) when loading, unloading application is pacified, it is intended that application is installed to certainSpecified user, or the application is unloaded in certain specified user.All users can also all be installed with application, or unloading application.
D) application B has been unloaded in user A, for other users, apply B still to exist, all visible application on desktopIcon, on other users, application B normally can be used.
Loading, unloading application is pacified for multi-user, the application of default installation can be installed to all users for having created (including masterUser and from user), and on each user's desktop generate application icon；And installed by file management under primary user shouldWith, be mounted only under primary user, primary user's desktop generate application icon, be not installed under user；Installation/the unloading of applicationAlso user can be specified based on user, user is specified in primary user and from user by specifying User IdentityThe installation of application/be discharged under certain user, certain user or all users is carried out；Being discharged under each user for same application is onlyStanding is carried out, and the application under a certain user is unloaded, does not affect the use of the application under other users.
3. user data management
A) related to system data user's id catalogue：The corresponding various system data storages of user are housed, for example：TableFace widget (component) list, arranges database, and default application starts strategy etc..
B) related to application packet data user's id catalogue：House user and the application bag catalogue that installs is corresponded to, if shouldData are generated with operation, then application data also deposits in this catalogue.
C) system SD card (Secure Digital Memory Card, safe digital card) catalogue：Each user sees certainlyOneself sdcard catalogue is all different, can only see the sdcard catalogue of oneself.
For user data management, under multi-user's realization mechanism, under each user, system data and application-dependent data are dividedDo not deposit under different data storage paths, e.g., under certain user, various system datas deposit in the first data storage that specifiesUnder path, and application data these application-dependent data that the application bag catalogue installed and application operating are produced are deposited in and are specifiedUnder second data storage path；Under each user, data storage is separate, and each user can only check the data storage of itself, such as certainlyThe sdcard catalogue of body.
4. user authority management
A) application after installation, applies the various authorities of application (for example：Read storage catalogue authority, read-write note powerLimit, opens camera authority etc.), can be divided into two parts, a part of insensitive authority, when application is installed, system is directly allowedApplication obtains authority；A part for example reads and writes note authority than more sensitive danger authority, can be when application is used, and system is carriedShow whether user allows application to obtain authority.
B) in different users, the authority to same application is independent and isolated, the base that an application is obtained to systemThis insensitive authority, after mounting, directly obtains in each user, and part than more sensitive danger authority isIndependent.For example：When user 0 opens wechat, if obtaining read-write note authority, when being switched to user 10, beat for the first timeWhen opening wechat, system still can prompt the user whether to allow, and will not remind because wechat obtains authority in user 0.WithReason, same in other users.
For user authority management, when under a certain user, application is installed, insensitive authority can directly obtain permission, sensitive powerLimit need to be obtained through user's license；Under different users, the authority configuration to same application is independent and isolated mutually, in userDuring switching, for the sensitive permission of the application for using for the first time, it is both needed to point out whether user assigns power.
In the present embodiment, open the process that set of applications realized based on multi-user's mechanism can be described as follows more：
Assume intelligent terminal default user be primary user, user under primary user pass through from application shop download or fromInstallation kit (package, APK) the file such as ABC.apk for applying ABC is stored in intelligent terminal by the modes such as other source copiesIn, after system installs ABC.apk under primary user, primary user's desktop can generate the icon of a main application ABC.When in primary userUnder detect for main application ABC attend to anything else request to create when, (if there is currently no from user, one can created from userIndividual from user, the establishment process cannot be completed in the case of discovering in user, without user setup account and password) underABC.apk is installed application of attending to anything else is obtained, in order to be distinguish between to main application and application of attending to anything else, can add for the new application of attending to anything else that installsPlus a mark (being assumed to be *), application of attending to anything else can be designated as ABC*.After ABC* installs success, may specify " installing successfully "Notice (in the notice also add mark *) be sent to the desktop reception under primary user, primary user to the notice after, generation oneThe individual icon with mark *, is made a distinction with the icon with main application ABC, and the icon can be used as to application of attending to anything else in primary userThe access port for being operated, after the icon is clicked, specified ABC* is being started under user by system, phase corresponding with ABC*Pass process is also in the operation under user, and the human-computer interaction interface (abbreviation interface) of ABC* is shown under primary user, nowThe interface of ABC* also can be used as access port application of attending to anything else operated in primary user.
For application of attending to anything else, the existence form of its access port in primary user can be diversified, this realityApply example to be not specifically limited, for example, it may be the desktop icons comprising application identities, the application identities should in order to currently to be attended to anything elseWith with main application and other application divisions of attending to anything else come；Can also be the application identities being additional on main application icon；May be used alsoTo be the icon comprising application identities existed with floating window form；Can also be the project for being present in the positions such as notice center.
Intelligent terminal user can achieve the operation to main application in primary user, while can also be by accessing in primary userMouth is operated to application of attending to anything else accordingly.It is understood that same main application can correspond to multiple applications of attending to anything else, each pointBody application be all installed in one different from user, the application that makes respectively to attend to anything else is separately operable in different from user, in fortuneIt does not interfere with each other during row.
Application being opened realize based on multi-user's mechanism to be advantageous in that more, for opening assistant's software compared to third party more,Avoid third party software advertisement and the generation of the behaviors such as privacy of user data is stolen, security is higher；Compare and answer with mainFor the scheme for all running under same user with application of attending to anything else, reduce difference under same user and attend to anything else application or main applicationBetween process interference, and the generation for avoiding afunction phenomenon that complicated running environment brought.
In this programme, when user needs to open multiple identical (i.e. main application and one or more applications of attending to anything else), multipleIdentical application can be while run, now the rate of load condensate of Installed System Memory can gradually rise in systems.In this step, terminal is obtainedIn equipment, the main memory usage for applying corresponding application of attending to anything else, exemplary, in android system, can be by applicationUID, process PID or userid come to main application and application of attending to anything else make a distinction, and then get main application corresponding attend to anything else shouldMemory usage.Wherein, memory usage characterizes the size of the shared internal memory of application of attending to anything else, and memory usage gets over Gao ZeThe system resource of consumption is bigger, otherwise less.The memory usage of the application of attending to anything else can be by dividing for opening under application of attending to anything elseBody process determines.Specifically, one attend to anything else apply using when can open one or more processes of attending to anything else, each process meeting of attending to anything elseCertain memory headroom is taken, the memory usage of the application of attending to anything else can be obtained by the memory usage sum of each process.
If the memory usage of step 102 application of attending to anything else is more than the first predetermined threshold value, application of attending to anything else described in judgementWhether meeting control condition, if meeting, the corresponding process of application of attending to anything else being controlled processing.
Exemplary, first predetermined threshold value can be 5%, 10%, 15% or 20% etc., can be arranged by system default,Also setting can be manually entered by user.When the memory usage of application of attending to anything else is determined more than first predetermined threshold value, that is, anticipateThe internal memory that taste its occupancy is higher, and the consumption to system resource is larger, now judges whether the application of attending to anything else meets control condition,The corresponding process of application of attending to anything else is controlled processing in the case of control condition is met.Wherein, process mainly includes：Ready state, execution state, blocked state, suspended state and final state etc..Wherein, can be right to the control process of processAbove-mentioned state of a process is switched over, exemplary, process is hung up and can discharge its corresponding memory source for taking, work as systemWhen memory source is sufficient, it is ensured that the process flow operation of system.
Skilled person will appreciate that, as main application is usually the main application that user opens, and only answered by mainOpen and can't badly influence the memory source of terminal device (existing terminal device hardware can support multiple main applicationsUnlatching), but as increasing for application of attending to anything else gradually can be consumed to system resource, therefore this programme is mainly for application of attending to anything elseThe internal memory of occupancy is controlled, but the control being equally applicable to main application.
The technical scheme of the present embodiment, obtains the main memory usage for applying corresponding application of attending to anything else in terminal device；IfThe memory usage of the application of attending to anything else is more than the first predetermined threshold value, then whether application of attending to anything else described in judgement meets control condition,If meeting, the corresponding process of application of attending to anything else being controlled processing, increasing with the number of applications that opens is solved,The memory source of system will be consumed, and thus cause system smooth can not run, have a strong impact on the experience effect of userProblem, it is achieved that user is capable of the smooth operation of safeguards system after multiple applications are opened, while also extending terminal deviceRun time, save system resource.
