Specific embodiment
In order to make the foregoing objectives, features and advantages of the present invention clearer and more comprehensible, with reference to the accompanying drawing and specific real
Applying mode, the present invention is described in further detail.
By taking remote operated tv product as an example, TV is generally using remote controller operation at a distance, on the one hand, user
Wish that enjoying contents more as far as possible by operation few as far as possible shows, on the other hand, TV has several specific independent mutually
Function, such as viewing live telecast video, watch Online Video, play game, check the media resource in peripheral equipment, Yi Jiyi
Dynamic equipment pushes media etc. to TV.
Currently, having function scene UI (User Interface, user interface) system in a kind of smart television, it is directly
Providing a user various function scenes, (hereinafter by function scene abbreviation Silo), user passes through remote controler one according to functional requirement
Key goes directly some function scene, the same type of resource of each function scene interior polymeric, services and applications.Wherein, should
Same type of resource, services and applications can be collectively referred to as pool of applications herein under function scene.Typical function
Can scene for example live telecast, video on demand, game center, using center, local media etc., be sane level shape between function scene
State removes homepage and Launcher, changes the starlike UI relationship frame of traditional center type.
Silo UI system simplifies the textual details of application program, so that product be made to be more suitable for user's operation, function scene
Between can pass through one key switching moment and save state and resume operation state.For example, user can be in viewing live streaming electricity
Apparent time one key switching continues the Online Video before viewing is left or one key switching to video on demand and continues to swim to game center
Play.
The Application Program Interface and state of each function scene in Silo UI system, all always background interface save and
Maintenance, and the maintenance of Application Program Interface and state needs to occupy running memory (RAM, random access in operating system
Memory), EMS memory occupation can be bigger when the Silo entered after booting is more.On low configuring product, running memory by
Not too large in the reasons such as market orientation and cost, when the application program that background interface saves state increases, running memory can not
Foot, therefore, Silo UI system has encountered following problem in low memory article:
Problem one: the operation for recycling memory causes the Caton of Application Program Interface and response slow.In order to allow user again
Open the application program run quick-recovery interface, operating system still can after Application Program Interface exits fastly
Continue the memory for retaining its occupancy, and user can be reduced using system spare memory after multiple application programs, when free memory is few
System carries out Memory recycle operation when a preset threshold value, when by the type of application process, user's level of interaction, use
Long, memory consumption size etc. calculates release sequence, to kill the process of application program one by one and recycle memory.When system is surplus
When remaining memory is in Near Threshold, if user continues to operate, Application Program Interface is possible to because frequently recycling memory is sent out
Raw Caton.It can also find in an experiment, the process and individual application programs of some critical services application programs still can after being killed
Voluntarily restart, then triggers Memory recycle operation again in system running memory deficiency and be killed, which repeatedly occurs, and causes
The multiple Memory recycle operation of system, will seriously affect the Application Program Interface response speed of complete machine.
Problem two: system recycling memory algorithm is not properly suited for Silo UI system, and the corresponding application program of Silo is rear
It is possible to be killed when platform interface, this, which will lead to when user switches back into function scene, needs to restart application program, not only
It is lost operating status and speed is slow.In presently used operating system, for background interface class application program, phase is used
Same Memory recycle numerical priority value, and the application program of the priority packet is often killed first to recycle memory.
The reason of above problem two is that operating system is designed towards the universal product, assumes all interface type applications all
There is same priority, therefore fails to distinguish which interface type using more important to user's meaning, to all background interfaces
Application Program Interface all remains memory, and recycling algorithm does not account for this demand when calculating yet.
Currently, for the intellectual product of general type, more companies, all can be when releasing low memory configurations product in the industry
System level carries out the optimization in terms of some memories.The quantity for reducing starting up's application program, prevents extra background service
Process voluntarily starts, and reduces the Application Program Interface the upper limit of the number that backstage saves, and limits the upper limit of the number etc. of background service process
Deng.
For example, existing optimisation strategy has in the industry: as soon as, after each Application Program Interface falls back on background interface, it is vertical
Carry out Memory recycle operation to it, two, the scheduling of snoop-operations system task stack, when task stack is moved to background interface, and
Its application program carries out Memory recycle to it when not including foreground interface.Both strategies are all by the memory of android system
Reclaimer operation is shifted to an earlier date, and just recycles memory immediately when Application Program Interface falls back on background interface, and advantage is the reduction of interior
Occupancy is deposited, system is also avoided until free memory reaches threshold value and just carries out Memory recycle, the Caton caused and frequently recycling
The problems such as, the disadvantage is that having violated operating system accelerates the original intention that background interface restores display, when user was again introduced into one once
When the Application Program Interface of opening, which needs to reload, and not only speed is slow but also state and data when running before
It can lose, user experience is poor.
For above-mentioned problem, the embodiment of the invention provides a kind of Memory recycle strategies of terminal device, for terminal
Memory recycle strategy is targetedly arranged in interface stack corresponding to pool of applications under functions of the equipments scene, specific next
It says, recycling is switched to the memory of the low recovery probability interface application of background interface in advance, reduces the interface stack of function scene
By the probability of Memory recycle, the Application Program Interface of assurance function scene can fast quick-recovery display under the premise of, reduce
Memory consumption.In the following, being described in detail by following embodiment.It should be noted that the terminal in the embodiment of the present invention is set
Standby can be TV, set-top box, naturally it is also possible to be smart phone, PC etc. other can be realized equipment of the invention.
Referring to Fig.1, a kind of step flow chart of the method for recovering internal storage embodiment of terminal device of the invention, institute are shown
Stating terminal device can be set one or more application collection of programs, and the application program in the pool of applications can have
There is a corresponding interface stack, the interface stack is configured with corresponding memory when in operating status；
The method can specifically include following steps:
Step 101, when pool of applications by foreground changing interface to background interface when, record the pool of applications
In interface stack in operating status；
In the embodiment of the present application, terminal device is pre-configured with multiple Silo according to functional requirement.Silo, that is, function scene,
There is corresponding pool of applications, pool of applications includes multiple application programs under function scene.
The application program of each Silo is equipped with corresponding Application Program Interface, when starting the Application Program Interface, makes
When its is in operating status, corresponding interface stack can be distributed for it, which is assigned corresponding memory, the start-up loading circle
Face finally completes application interface drafting.
In one preferred embodiment of the invention, application program includes special case application program, root application program, top application
Program and intermediate application program, then corresponding interface stack is properly termed as root interface stack, pushes up interface stack, special case interface stack and middle boundary
Face stack.Specifically, root interface stack pushes up interface stack, and the differentiation of special case interface stack and intermediate interface stack is as follows:
One, root interface stack: each Silo configures a root application program, which there is corresponding to be applied boundary
Face.It requests to show the root application interface, operating system meeting from Silo manager to operating system when starting some Silo for the first time
Start the process of the root application program of the Silo, then interface stack for its distribution is known as root interface stack, the start-up loading interface,
Finally complete the drafting of root application interface.
Two, it pushes up interface stack: multiple interface stacks can be run at the same Silo, the interface stack of Silo is used according to user
Sequence, which divides, corresponding runlevel, wherein being in the interface interface the Zhan Weiding stack of top in the interface of foreground.
Three, special case interface stack: some application programs are that can be used under whole Silo, for example, setting application, system interface
Application certain interfaces, and with other complete machine interaction control interfaces, these interfaces are referred to as special case interface, corresponding interface
Stack is special case interface stack.
Four, intermediate interface stack: the root application interface of Silo is located in the stack of root interface, and multiple interfaces, which jump, generates multiple interfaces
Stack, the interface interacted at foreground interface with user are located in the interface stack of top, ran from the stack of the root interface interface Zhan Daoding
Other interface stacks be referred to herein as intermediate interface stack.
From the foregoing, the interface stack that root interface stack and special case interface stack are usually fixed, and intermediate interface stack and top circle
It can then be replaced mutually between the stack of face, when the interface stack at the top of foreground is then top interface stack.Certainly, according to different terminals
The configuration conversion regime of equipment, interface stack may be different, and the embodiment of the present invention need not be limit to this.
In a kind of preferable example of the invention, in some Silo by foreground changing interface to background interface when, will start to receive
Collect and distinguish interface stack in operating status, specifically refers to that special case interface stack, root interface stack push up interface stack and middle boundary
Face stack, then the step 101 may include following sub-step:
Sub-step S11 determines the root interface of the pool of applications using preset pool of applications configuration file
Stack；
Also, the step 101 can also include following sub-step:
Sub-step S12 determines top interface stack and special case circle in the pool of applications using the runlevel
Face stack；
Sub-step S13, records special case interface stack, the root interface interface Zhan Heding stack, and, record the application program
Set removes special case interface stack, and the interface record stack except the stack of the root interface interface Zhan Heding is intermediate interface stack.
It should be noted that the step of above-mentioned determining root interface stack, top interface stack and special case interface stack, that is to say sub-step
S11 and sub-step S12 has no successive point, and without dependence, sequentially number is used for the purpose of text composition, and people is facilitated to read
It reads.
It since there is no time sequencings for these steps, so cannot successively write, can independently carry out, and mutual not shadow
It rings, they can select asynchronous execution or be performed simultaneously, the embodiment of the present invention is not subject to this according to terminal actual conditions
Limitation.
Certainly, certain steps in embodiments of the present invention using asynchronous execution or can be equally performed simultaneously, the present invention
Embodiment is equally not necessarily to this to limit.
In one preferred embodiment of the invention, the sub-step S12 may include following sub-step:
Sub-step a11 obtains the highest interface stack of runlevel in the pool of applications；
The highest interface stack of the runlevel is determined as top interface to be determined stack by sub-step a12；
Whether sub-step a13 uses preset special case configuration file to judge the top interface to be determined stack for special case interface
Stack；If so, executing sub-step a14；If it is not, then executing sub-step a18；
Sub-step a14, recording the top interface stack to be determined is special case interface stack；
Sub-step a15 searches the interface stack in the top interface stack next stage to be determined according to the runlevel；
Sub-step a16, using the interface stack of the next stage as top interface to be determined stack；
Sub-step a17, return it is described use preset special case configuration file judge the top interface to be determined stack whether as
The step of special case interface stack；
The top interface to be determined stack is determined as pushing up interface stack by sub-step a18.
Step 102, interface stack to be recycled is determined in the interface stack；
In one preferred embodiment of the invention, the step of step 102 can be following sub-step:
Special case interface stack and intermediate interface stack in the interface stack is determined as interface to be recycled by sub-step S21
Stack.
In a particular application, due to special case interface stack and intermediate interface stack be all user without the need for be further continued for using boundary
Face stack so will not influence the operating experience of user even if recycling memory to it, therefore can be considered as interface stack to be recycled,
It is operated to subsequent Memory recycle.
Step 103, the memory that the interface stack to be recycled is configured is recycled.
After determining interface stack to be recycled, when complete Silo by foreground changing interface to background interface after, so that it may needle
Operating for recycling memory is carried out to interface stack to be recycled.
In a kind of preferable example of the invention, Silo can be understood as grouping when application program operation, each Silo
In include multiple application programs, every group of application program generally can all have relevant business relations, such as live telecast, video point
Broadcast, game center, using center, local media etc..Each Silo can define a root application interface, for the first time starting one
Silo is actually to start this root application interface, and the root application interface is assigned corresponding interface stack, the root interface
Stack is assigned corresponding memory.
Wherein, it may include sub-interface or Application Program Interface on root application interface, can further be wrapped in sub-interface
Application program is included, therefore user can operate the interface for opening sub-interface or other applications on root application interface,
Then, root application interface can add flag bit, and the new interface for informing that operating system is opened needs to operate in current interface stack
Or a new interface stack, the application program for being activated interface can also voluntarily specify the interface to operate on startup currently
In interface stack or new interface stack.Therefore, multiple interface stacks are generated when Silo is run, these interfaces may come from multiple answer
Use program.
Each Silo has corresponding pool of applications.Silo management system is that each Silo configures Silo circle
Face stack set records and manages the Application Program Interface stack wherein run.Specifically as shown in Fig. 2, the root application interface position of Silo
In the stack of root interface, multiple interfaces, which jump, generates multiple interface stacks, and the interface interacted at foreground interface with user is located at top
In the stack of interface, other interface stacks run from the stack of the root interface interface Zhan Daoding are referred to herein as intermediate interface stack.Each Silo
Necessarily there is the root interface interface Zhan Heding stack.If Silo has only run root application interface, the root interface interface Zhan Heding stack is same
A stack does not have intermediate interface stack at this time.
When user's handoff functionality scene, Silo manager starts transition animation in the interface of foreground, background interface into
The starting of the new Silo of row and the preservation of old Silo state.Multiple interface stacks in the stack set of the new interface Silo are restored to foreground interface
Or directly initiated when first time, the interface Zhan Ji credit union of old Silo is moved to background interface, it should be noted that this time shift
Move the interface stack set still committed memory of the old Silo of background interface.
It is appreciated that the interface stack retained in memory after multiple Silo operation can be very more, it is surplus to be likely to result in system
Remaining memory is nervous.A large amount of tests are found, in system spare there are Near Threshold or after being lower than threshold value, if user continues into operation
The Memory recycle operation of system can be frequently triggered, Caton occurs for the response speed for reducing interface.Operating system is only in free memory
Memory recycle operation is just carried out when lower than threshold value, a small amount of memory released is consumed and is recycled quickly, frequently recycling behaviour
Make initiation Caton.Use demand of this Memory recycle mode not in full conformity with Silo UI system.
By collecting and surveying user behavior and statistics interface stack log, it is found that multiple interfaces of a Silo
In stack, general user can only use in root application interface stack and the top enterprising enforcement of application interface stack, the intermediate interface stack that centre generates
It is hardly again introduced into, this is determined by the functional characteristic of Silo UI system, other interface stacks on the stack of root interface are all
Started by root application interface, terminates generally return to root application interface stack after use is retracted.Therefore, user switches a Silo
Afterwards, it can only retain the root interface interface Zhan Heding stack, the memory that intermediate interface stack occupies is recycled in advance, in release residue
It deposits.
Specifically, the process of active releasing memory is as follows when Silo switches:
1) when Silo switching starts, the information of all interface stacks of foreground interface operating status is recorded, text is configured according to Silo
Current Silo root application interface information determines root interface stack in part, is determined and is pushed up according to operating system current top active interface information
Portion interface stack, other interface stacks are denoted as intermediate interface stack.
2) top interface stack is reaffirmed.This is the special operation determined by Silo UI system performance.Some application programs are
It can be used under whole Silo, for example, certain interfaces of setting application, system interface application, and controlled with the interaction of other complete machines
Interface processed, these interfaces are referred to as special case interface, and corresponding interface stack is special case interface stack.They are not belonging to any Silo,
To no longer restore to show after Silo is switched back, but restore the Silo operation when its under next stage interface stack.Therefore, this
A little special case interfaces stack can be recycled safely.It should be noted that when the application program in Silo is run, it can be according to user
Using journal, its sequencing run can know fortune according to Silo runlevel to obtain Silo runlevel
Application program of the row in top interface stack.
Special case interface stack information factory before it is preset in the application, Silo manager initialize when loaded.
The identification information of Silo manager comparison top interface stack median surface is just gradually searched downwards next if it is above-mentioned special case interface
Non- special case interface stack is recorded as top interface stack until finding non-special case interface stack by grade interface stack again.
3) stack list in interface to be recycled is determined.Intermediate interface stack and special case interface record stack are to stack list in interface to be recycled
In, do not carry out reclaimer operation directly at this time, but after the new interface Silo stack completes foreground Interface Moving and display is drawn again
It carries out, the reason is as follows that: when the top interface stack run in operating system is exited or disappeared, operating system can restore the interface under it
Stack is to guarantee that user can continue to see and operation interface, the interface stack for being restored to foreground interface can execute a series of Life Cycles
Phase function finishing service logic, some service logics can trigger audio and video playing or some settings operation, Silo caused to switch
The exception of journey.On the other hand, triggering shot operation can be also synchronized when Silo switching starts, screenshot is used as transition animation, cuts at this time
The confusion of screenshot may be caused by changing interface.
4) Silo switches, and the new interface Silo stack is waited to complete foreground Interface Moving and display drafting.
5) after the completion of Silo switching, the memory of interface stack is recycled.To the median surface stack of stack list in interface to be recycled one by one into
Row removes operation, and distributing operation system interface kills the corresponding program process in the interface, and process is killed its rear occupancy
Memory can be released immediately as free memory.Noticing has other critical services cannot inside some program process
It is killed, the information of such application program is preset in Silo manager software, and interface stack is only carried out to it and removes operation.
In embodiments of the present invention, each Silo of background interface can only cache the root interface interface Zhan Heding in memory
Stack currently can then possess multiple intermediate interface stacks in the Silo of foreground interface operation, and the presence of intermediate interface stack ensure that use
Other interfaces of family recent visit can be rapidly restored.
From test result, one program process of every kill can recycle more than ten MB of memory to more than 100 MB
It differs, then the memory of average each application program is about in twenties MB or so.The same of this embodiment of the present invention is not used in comparison
Product can obviously observe that the free memory of product after improving is more sufficient, and system is grasped by the complicated user of higher-strength
Free memory can be just triggered after work lower than system thresholds, after Caton phenomenon occurs in comparison machine low memory, improved products is still
Smoothness operation.
In one preferred embodiment of the invention, the interface stack may include critical services interface stack, the step
103 may include following sub-step:
Sub-step S31, when the pool of applications by foreground changing interface to background interface after, judge described to be recycled
Interface stack in whether be important service interface stack；If so, sub-step S32 is executed, if it is not, then executing sub-step S33；
Sub-step S32 does not recycle the memory that critical services interface stack is configured；
Sub-step S33 recycles the memory that the interface stack to be recycled is configured.
In one preferred embodiment of the invention, the interface stack has corresponding recycling priority, the sub-step
S31 may include following sub-step:
Sub-step a21 judges the corresponding recycling priority of the interface stack to be recycled, if it is preferential to be higher than preset recycling
Grade；If so, executing sub-step a22；
The interface stack to be recycled higher than preset recycling priority is determined as critical services interface by sub-step a22
Stack.
In low memory configurations product, after user starts excessive Silo and depth use, in this case it is still possible to will cause and be
The phenomenon for free memory deficiency of uniting causes operating system recycling memory and kills background application.In order to guarantee user between Silo
When switching, the interface Silo can fast quick-recovery and the state before keeping, even if Installed System Memory deficiency is also required to retain as far as possible
The Silo interface application process on backstage.The process of each top Silo interface application should be than the process of common applications
(namely being non-Silo application program) possesses slightly higher priority.
In a kind of example of the invention, when operating system carries out the Memory recycle operation of application program, one is first calculated
Recycle priority, according to the application component type of application program, user's level of interaction, whether system core process etc. factor
Comprehensive descision obtains corresponding recycling priority.
Wherein, recycling priority can be divided into from high to low according to significance level: system (System) is resided
(Persistent), foreground (Foreground), visual (Visible), (Perceptible), service can be perceived
(Service), it caches (Cached) etc..General interface type application program can be assigned to " slow when falling back on background interface
Deposit " rank, it can be recycled in advance when memory anxiety.System is general when the application program at each interface Silo falls back on background interface
Also " caching " rank can be distributed for it.
In order to guarantee the fast quick-recovery in interface after Silo switching, need to improve the process of the corresponding application program in the top Silo interface
Priority in algorithm is recycled in background interface, concrete mode is as follows:
1) to Silo manager open interface in the process management services of operating system application program, which can be repaired
Change the numerical priority value in the proceeding internal memory recycling algorithm of single application program.
2) after converting Silo, Silo management system inquiry operation system is the process for the application program that previous Silo pushes up interface
The numerical priority value of distribution.If the numerical value is less than or equal to " service " rank, above-mentioned interface is called to be revised as slightly higher rank.
In actual use, it is provided with " can perceive " rank for it, system has recycled the process of " caching " and " service " level applications program
The rank can be just recycled afterwards, and the probability for recycling of being killed is very low.If the application program itself at the previous top Silo interface is high excellent
First level application, numerical priority value can be " system " or " resident ", not need to intervene in such cases.As some Silo circle
When face is shown to top interface stack, operating system can set " foreground " for its preferred value numerical value automatically, can not do intervention i.e. at this time
It can.
In summary, the improvement in the embodiment of the present invention for the Memory recycle strategy of terminal device mainly enters in terms of two
Hand:
First, actively recycling the memory that non-Silo application program occupies after Silo switching；
Second, priority of the top the Silo interface application on backstage in Memory recycle algorithm is improved when Silo switches,
Important application program is avoided to be recovered.
In the embodiment of the present invention, application program is grouped by terminal device according to functional requirement, then available each
Corresponding pool of applications under function scene, when application program operation in pool of applications, system is that it distributes interface
Stack and memory, when arbitrary pool of applications by foreground changing interface to background interface when, record the pool of applications
Interface stack in operating status, and therefrom further determine that interface stack to be recycled, finally successfully cut in pool of applications
After changing to background interface, the recycling of the interface stack memory to be recycled is carried out.It, can be according to using journey using the embodiment of the present invention
Ordered sets switches to discharge extra memory, and it is existing to reduce Caton caused by system recycling memory for free memory in increase system
As.For low configuring product lesser for memory of the embodiment of the present invention, there is very high practicability.In addition, the present invention is implemented
The application program in pool of applications is provided with recycling priority in example, it, can root after determining interface stack to be recycled
Reclaimer operation is sequentially carried out according to its priority, wherein if in interface stack to be recycled including the important clothes of important application program
Business interface stack, then without reclaimer operation, thus when guaranteeing that application program needed for system is switched to background interface, not because of memory
Recycling is killed.
In one preferred embodiment of the invention, in described the step of recycling the memory that interface stack to be recycled is configured
Later, after that is to say step 103, can also include the following steps:
When the pool of applications again switches to foreground interface by background interface, restore the pool of applications
The corresponding Application Program Interface of the root interface interface Zhan Heding stack to foreground interface.
