Terminal in the embodiment of the present invention can comprise smart mobile phone (as Android phone, iOS mobile phone, WindowsPhone mobile phone etc.), panel computer, palm PC, notebook computer, mobile internet device (MID, or Wearable etc. MobileInternetDevices), above-mentioned terminal is only citing, and non exhaustive, including but not limited to above-mentioned terminal.

Referring to Fig. 1, is the first embodiment schematic flow sheet of a kind of internal memory method for cleaning that the embodiment of the present invention provides.Internal memory method for cleaning described in the present embodiment, comprises the following steps:

S101, when receiving the intended application enabled instruction of input, terminal obtains the first memory value of taking when the pre-recorded described intended application of described terminal on average uses at every turn.

Wherein, this terminal can install types of applications, as social class application (comprising QQ, micro-letter etc.), amusement class application (comprising driving, the Great War of whole people's aircraft etc. everyday), office class application (comprising Baidu's cloud, WPSOffice etc.), video class application (comprising excellent cruel, Tengxun's video etc.), shopping class application (comprising Taobao, Jingdone district etc.) and payment financing class application (comprise Alipay wallet, dig wealth book keeping operation etc.), etc.

In the embodiment that some are feasible, in the use procedure of each application of terminal installation, terminal can record the operational factor of each application, this operational factor can comprise the memory value of the terminal that each run takies, and then each application can be obtained from being installed to now, or the characteristic informations such as the memory value taken when the duration of the access times in a period of time, on average each use and average each use, these characteristic informations can apply the form storage using record sheet.

It should be noted that, tag memory in the present embodiment refers to the running memory of terminal, i.e. random access memory ram (English full name: RandomAccessMemory), some application datas when application runs and data cached etc. understand the certain memory value (memory headroom) of occupied terminal.

In specific implementation, user is by clicking the mode of the application icon of intended application or speech control mode or gesture control mode on the touchscreen, input the enabled instruction for this intended application, after terminal detects this enabled instruction, start this intended application and shown the application interface of this intended application by display screen, meanwhile, terminal obtains the first memory value of the terminal taken when this pre-recorded intended application on average uses at every turn.

It is to be noted, this display screen accessible site is in this touch-screen, thus this touch-screen can integrate touch-control and Presentation Function, namely in embodiments of the present invention, namely the touch-screen of terminal can be used as contact panel and is supplied to the operations such as user carries out touching, click, also can be used as display screen, represent corresponding data message to terminal user.

Whether the first memory value described in S102, described terminal judges is more than or equal to the current available memory value of described terminal, if so, then performs step S103, if not, then terminates this flow process.

Concrete, first terminal can obtain current available memory value, the i.e. current memory value not being employed process and taking, and then this first memory value and this current available memory value are compared, to determine that can this intended application normally be run after starting, if this first memory value is less than this current available memory value, show that this intended application can normally be run; If this first memory value is more than or equal to this current available memory value, shows that current available memory value is not enough to support the normal operation of this intended application, now can perform step S103.

In the embodiment that some are feasible, terminal specifically can judge that this current available memory value deducts the difference that this first memory value obtains and whether is more than or equal to default memory threshold (as 50M), to determine that can this intended application be smoothly run after starting, if this difference is more than or equal to this memory threshold preset, show that this intended application can smoothly be run after starting; If this difference is less than this memory threshold preset, shows that current available memory value is not enough to support that the smoothness of this intended application is run, now can perform step S103.

For example, mobile phone with terminal, this intended application is game application A is example, the memory threshold preset is 50M, the first memory value that the game application A of mobile phone record takies when on average using at every turn is 200M, suppose that the current available memory value of mobile phone is 230M, now the current available memory value 230M of mobile phone deducts the difference of the first memory value 200M taken when game application A on average uses at every turn is 30M, because 30M is less than default memory threshold 50M, now can not ensure that this game application A can smoothly run in whole use procedure, therefore mobile phone need discharge a part of memory source, step S103 can be performed.

S103, described terminal obtain characteristic information that pre-recorded current of described terminal is in each application of background operation state, and described characteristic information comprises access times, average each duration of using and average each memory value taken when using.

In specific implementation, terminal determines current each application being in background operation state, so from the application that generates in advance use record sheet the access times obtaining this each application, average each duration of using and average each use time the characteristic information such as the memory value that takies.

S104, described terminal, according to described first memory value, the current available memory value of described terminal and the described characteristic information that each is applied, determine the application needing to carry out internal memory cleaning in each application described.

In specific implementation, the first memory value that terminal takies when can first on average use according to this intended application at every turn and current available memory value, determine the memory value needing to be obtained by the application of cleaning running background, determine that in this each application, user seldom uses according to access times and the average each duration used again, use the application that duration is shorter, and then user seldom uses in applying this each, the application using duration shorter is as the application that can clear up, and obtain the memory value taken when each application on average uses at every turn in these applications that can clear up, and then obtain the number of applications needing cleaning in these applications that can clear up.

In the embodiment that some are feasible, application in the application that terminal can be able to be cleared up according to these enters the time order from morning to night of running background, obtain the number of applications needing cleaning, the application namely entering this number of applications of running background at first can be cleaned.

In the embodiment that some are feasible, the current memory value taken on backstage of application order from big to small in the application that terminal can be able to be cleared up according to these, obtain the number of applications needing cleaning, namely, after the current memory value taken on backstage arranges from big to small, the application coming this number of applications above can be cleaned.

It should be noted that, user is set to the application (do not allow when namely these are applied in running background cleaned fall) of backstage guard mode, terminal can be cleared up.

S105, described terminal perform internal memory cleaning operation to the application that described need carry out internal memory cleaning.

Concrete, terminal directly can remove the application need carrying out internal memory cleaning or the application this need being carried out internal memory cleaning are transferred to terminal swap subregion from the internal memory of terminal from internal memory, perform internal memory cleaning operation with the application realizing need carrying out this internal memory cleaning, thus provide enough memory sources for the operation of this intended application.

Referring to Fig. 2, is the second embodiment schematic flow sheet of a kind of internal memory method for cleaning that the embodiment of the present invention provides.Internal memory method for cleaning described in the present embodiment, comprises the following steps:

In terminal described in S201, terminal record, each application is from the memory value taken when being installed to current access times, the duration used and using at every turn at every turn.

Wherein, each duration used can be application each time from being opened to the duration exiting experience completely, also can be application from being opened to the duration entering running background experience.

S202, described terminal are according to the duration of described access times and described each use, determine the average each duration used of each application described, and according to the memory value taken when described access times and described each use, the memory value taken when each applies average each use described in determining.

Concrete, terminal can according to each application of record from being installed to now, or the access times in a period of time and each duration used, calculate the average each duration used of each application, simultaneously, also can according to each application of record from being installed to now, or access times in a period of time and each memory value taken when using, calculate the average each memory value taken when using of each application.

The memory value taken when the duration of described access times, described on average each use and described average each use is set to each characteristic information applied described by S203, described terminal.

S204, when receiving the intended application enabled instruction of input, described terminal obtains the first memory value of taking when the pre-recorded described intended application of described terminal on average uses at every turn.

Whether the first memory value described in S205, described terminal judges is more than or equal to the current available memory value of described terminal, if so, then performs step S206, if not, then terminates this flow process.

Concrete, first terminal can obtain current available memory value, the i.e. current memory value not being employed process and taking, and then this first memory value and this current available memory value are compared, to determine that can this intended application normally be run after starting, if this first memory value is less than this current available memory value, show that this intended application can normally be run; If this first memory value is more than or equal to this current available memory value, shows that current available memory value is not enough to support the normal operation of this intended application, now can perform step S206.

In the embodiment that some are feasible, terminal specifically can judge that this current available memory value deducts the difference that this first memory value obtains and whether is more than or equal to default memory threshold (as 50M), to determine that can this intended application be smoothly run after starting, if this difference is more than or equal to this memory threshold preset, show that this intended application can smoothly be run after starting; If this difference is less than this memory threshold preset, shows that current available memory value is not enough to support that the smoothness of this intended application is run, now can perform step S206.

S206, described terminal obtain characteristic information that pre-recorded current of described terminal is in each application of background operation state, and described characteristic information comprises access times, average each duration of using and average each memory value taken when using.

S207, described terminal determine that in each application described, access times or average each duration used are less than or equal to the application of predetermined threshold value, and the memory value taken according to described first memory value, the current available memory value of described terminal and when on average using at every turn, determine that the duration of described access times or average each use is less than or equal to the destination number needing the application carrying out internal memory cleaning in the application of predetermined threshold value.

In specific implementation, according to access times and average each duration used, terminal can judge whether an application is the application that user often uses, and then in applying this each, access times are less than or equal to predetermined threshold value (as 5 times), or the average each duration used is less than or equal to predetermined threshold value (as 3 minutes), or access times are less than or equal to predetermined threshold value (as 5 times) and the application that average each duration used also is less than or equal to predetermined threshold value (as 3 minutes) is defined as the application that can clear up.

Further, the memory value that terminal takies according to the first memory value, the current available memory value of this terminal and when on average using at every turn, determines the destination number needing the application carrying out internal memory cleaning in this application that can clear up.

S208, described terminal are according to the selection rule preset, be less than or equal to from described access times or average each duration used the application determining described destination number the application of predetermined threshold value, and the application of described destination number is set to the application that described need carry out internal memory cleaning.

In the embodiment that some are feasible, terminal can record access times or average each being less than or equal in the application of predetermined threshold value of each duration used applies the time point entering background operation state, and then according to entering the time point order from morning to night of background operation state, the application determining this destination number the application of predetermined threshold value is less than or equal to from these access times or average each duration used, and the application of this destination number is set to the application need carrying out internal memory cleaning, namely when needs carry out internal memory cleaning, these access times or the average each duration used be less than or equal in the application of predetermined threshold value enter running background application more early more first cleaned fall.

In the embodiment that some are feasible, terminal can obtain access times or average each being less than or equal in the application of predetermined threshold value of each duration used applies the current memory value taken, and then according to current committed memory value order from big to small, the application determining this destination number the application of predetermined threshold value is less than or equal to from these access times or average each duration used, and the application of this destination number is set to the application need carrying out internal memory cleaning, namely when needs carry out internal memory cleaning, these access times or the average each duration used be less than or equal to application that in the application of predetermined threshold value, the current memory value taken is larger more first cleaned fall.

In the embodiment that some are feasible, terminal also can be less than or equal to from these access times or average each duration used the application determining this destination number the application of predetermined threshold value at random, and the application of this destination number is set to the application need carrying out internal memory cleaning.

S209, described terminal perform internal memory cleaning operation to the application that described need carry out internal memory cleaning.

For example, suppose terminal to be provided with 5 application, be respectively application A, B, C, D and E, terminal record from be installed to now (or in nearest 2 months) these 5 application characteristic information (comprise access times, average each duration of using and average each use time the memory value that takies) as shown in table 1:

Table 1

Wherein, application E off-duty, and apply A, B, C and D is in background operation state, the current available memory value of terminal is 60M, when the enabled instruction for application E that user inputs being detected, first terminal obtains the memory value 100M taken when application E on average uses at every turn, because the memory value 100M taken when application E on average uses is greater than current available memory value 60M at every turn, now need to carry out internal memory cleaning, first terminal obtains application A, B, C and D access times separately, the characteristic informations such as the memory value taken when the average duration at every turn used and average each use, and pass through application A, B, the application of the less use of user is determined in the access times of C and D and/or the comparison of average each duration used, namely A is applied, B and D, the memory value 100M taken when now on average at every turn using according to application E and current available memory value 60M draws the normal operation at least needing the internal memory guarantee application E discharging 40M, again according to application A, the memory value taken when B and D average each uses can be determined and this two methods of application A and B is cleaned out the normal operation that can meet application E from tag memory, free memory value now equals to apply the memory value 100M taken when E on average uses at every turn.

Further, for ensureing the operation that application E is more smooth, terminal is greater than certain default memory threshold (as 20M) by clearing up the memory value 100M taken when some background application make free memory value on average use with application E more at every turn, thus application D cleans out to make free memory value for 125M by terminal again, the memory value 100M taken when on average at every turn using than application E has more 25M, thus can ensure to apply the more smooth operation of E.

The average each duration used of this each application can be determined according to each application in the terminal of record from the duration being installed to current access times and each use by the embodiment of the present invention, and the memory value taken when at every turn using according to these access times and this determines the average each memory value taken when using of this each application, so by these access times, this average each duration of using and this average each use time the memory value that takies be set to characteristic information of this each application, when the intended application enabled instruction receiving input, obtain the first memory value taken when this pre-recorded intended application on average uses at every turn, and judge whether this first memory value is more than or equal to the current available memory value of terminal, if, then obtain the current characteristic information being in the first application of background operation state in this pre-recorded terminal, this characteristic information comprises access times, the memory value taken when the average duration at every turn used and average each use, determine that in this each application, access times or the average each duration used are less than or equal to the application of predetermined threshold value, and according to this first memory value, the memory value taken when the current available memory value of this terminal and average each use, determine that these access times or average each duration used are less than or equal to the destination number needing the application carrying out internal memory cleaning in the application of predetermined threshold value, the application of this destination number is determined according to the selection rule preset, and the application of this destination number is set to the application need carrying out internal memory cleaning, and then internal memory cleaning operation is performed to the application that this need carry out internal memory cleaning, internal memory cleaning operation can be completed in application start process, thus effectively ensure that the smoothness of application is run.
