The embodiment of the present application provides a kind of information storage means, device, storage medium and electronic equipment.
A kind of information storage means, applied to the first electronic equipment, including:Application message to be stored is obtained, the application Information includes intended application mark and target handover information;Identified according to the intended application from stored application queue storehouse really Determine first object queue, which includes at least one application queue, and each application queue includes at least one switching Information;The first object queue is updated according to the target handover information, to store the application in the application queue storehouse Information;The application queue storehouse is updated according to the first object queue after renewal.
As shown in Figure 1, the idiographic flow of the information storage means can be as follows:
101st, application message to be stored is obtained, which includes intended application mark and target handover information.
In the present embodiment, which is the unique identification mark of application program, it can be with It is Apply Names.The handover information (or target handover information) refers mainly to apply relevant information when switching to foreground, for example cuts Upper foreground application for change the moment, being switched etc..
102nd, first object queue is determined from stored application queue storehouse according to intended application mark, this applies team Row storehouse includes at least one application queue, and each application queue includes at least one handover information.
In the present embodiment, which is used for the switching for storing all applications that foreground is had switched in historical period Information, each handover information are to be stored by the sequencing of switching time in respective application queue, the application queue Can be FIFO (First Input First Output, first in, first out) queue, it is a kind of data structure of first in first out, Handover information can only be sequentially written in, sequentially reads handover information.
For example, the application queue storehouse further includes at least one application identities, each application identities correspond to an application queue, At this time, above-mentioned steps 102 can specifically include:
The intended application is identified and is matched with the application identities;
If successful match, using the corresponding application queue of the application identities of the successful match as first object queue;
If it fails to match, intended application mark is stored in the application queue storehouse, and creates one and is answered with the target With corresponding empty application queue is identified, as first object queue.
In the present embodiment, stored application queue and application identities are associated storages in the application queue storehouse, such as It can be associated using application identities as key (Key) using application queue as the value (Value) of the key.Electronic equipment can be with The application queue each applied is established in advance, and corresponding application queue can also be just established when application starts first.When application is first When secondary startup just creates corresponding application queue, if there is no the application queue of current foreground application, Ke Yigen in application queue storehouse The application identities applied according to current foreground establish an empty First Input First Output, the application queue as current foreground application.
103rd, the first object queue is updated according to the target handover information, to be stored in the application queue storehouse The application message.
For example, above-mentioned steps 103 can specifically include:
The target handover information is stored in the tail of the queue of the first object queue;
When the target handover information adds successfully, the quantity of handover information in the first object queue is counted, as One quantity;
Judge whether first quantity is more than the first predetermined threshold value;
Deleted if so, then most forward default number of branches handover information will be ranked in the first object queue.
,, can be new by this when getting new handover information every time for the application queue of first in, first out in the present embodiment Handover information be stored in the end of respective application queue.First predetermined threshold value can be real depending on actual memory size Border memory is bigger, its first predetermined threshold value can be bigger, for example first predetermined threshold value can be 100.The default number of branches can be with It is the numerical value being manually set, such as 5.The number ratio that foreground is switched to using (abbreviation frequency applications) is used generally, due to high frequency It is more, thus the handover information stored in its corresponding application queue also should more (namely queue length is longer), to avoid high frequency The excessive occupancy Installed System Memory of the handover information of application, so as to cause the switching of no enough memory storage low frequency applications to be believed Breath, can limit the maximum length (the first predetermined threshold value) of each application queue, namely whenever there is new handover information to be stored in When in corresponding application queue, whether the length that can detect the application queue exceedes maximum length, if exceeding, carries out data and deletes Subtract, it is contemplated that apart from current time it is more remote data reference value it is lower, therefore can by storage time at most (namely come should Before queue) single or part handover information deleted.

Bank of queues after the sequence is updated according to the total quantity.
In the present embodiment, since the application queue storehouse is generally stored inside in the Installed System Memory of electronic equipment, to avoid memory Space hold is excessive, when data volume can be controlled in certain scale, namely stores new handover information every time, is required for The total amount of handover information in the application queue storehouse is detected, is deleted according to the total amount to determine to carry out data.
For example, above-mentioned steps " being updated according to the total quantity to bank of queues after the sequence " can specifically include:
Judge whether the total quantity is more than the second predetermined threshold value;
Most forward application queue is ranked in bank of queues after the sequence if so, then choosing, as queue to be updated;
Corresponding second quantity of the queue to be updated is obtained, and according to preset ratio and the queue corresponding second to be updated Quantity determines destination number;
Preceding destination number bar handover information in the queue to be updated is deleted, to be updated to the queue to be updated.

For example, front stage operation application can be monitored in real time, when finding that the front stage operation application changes, will can be become The application identities and change the moment as to be stored that the operation before the application identities for running application, change after change is applied Application message.
202nd, the first electronic equipment carries out intended application mark with the application identities in stored application queue storehouse Matching, if successful match, using the corresponding application queue of the application identities of the successful match as first object queue, if matching Failure, then store intended application mark in the application queue storehouse, and creates one and the corresponding sky of intended application mark Application queue, as first object queue.
For example, Fig. 3 is referred to, when user starts a certain app, can be set by hashmap (Hash mapping) in electronics The corresponding handover informations of the App are established in standby, wherein key is app application names, and value is that the FiFo of a first in, first out (first enters First go out) queue, each FiFo queues correspond to the handover information of corresponding app.Such as the application identities stored in the application queue storehouse It can include { App1, App2 ... Appx }, intended application mark can be Appi, at this point it is possible to hashmap is inquired about according to i, If i ∈ (1,2 ... x), showing successful match, the application queue of successful match is the corresponding application queues of Appi, if Then show that it fails to match, it is necessary to create the corresponding FiFo queues of Appi.
203rd, the first electronic equipment stores the target handover information in the tail of the queue of the first object queue, and when the target is cut When changing information and adding successfully, the quantity of handover information in the first object queue is counted, as the first quantity.
204th, the first electronic equipment judges whether first quantity is more than the first predetermined threshold value, if so, then by first mesh Most forward default number of branches handover information is ranked in mark queue to be deleted, if it is not, then can directly perform following step 205.
For example, which can be 100, which, which can be that 1, Appi is corresponding, answers It is Queuei with queue, Ni bar handover informations, such as Appi_1, Appi_2...Appi_Ni can be included in Queuei, when Stored handover information is more than 100 in the corresponding fifo queues of Appi, namely, it is necessary to delete handover information during Ni > 100 Appi_1。
205th, the first electronic equipment counts the quantity of handover information in each application queue, as the second quantity, and according to The order of second quantity from big to small is ranked up the application queue in the application queue storehouse, bank of queues after being sorted, Afterwards according to the second quantity amount of totalizing.

208th, the first electronic equipment determines destination number according to preset ratio second quantity corresponding with the queue to be updated, And preceding destination number bar handover information in the queue to be updated is deleted, to be updated to the queue to be updated.
For example, which can be 1000, which can be 10%.N1, N2...Nx can be calculated Summation SUM, if SUM is more than 1000, for example when 1005, the Queue5 of ranking first can be obtained, if the switching in Queue5 Second quantity N5 of information is 90, then the destination number is 90*10%=9, namely 9 handover informations are deleted before selection.
209th, the first electronic equipment calculates current difference between the total quantity and destination number, and whether judges the difference Less than or equal to the 3rd predetermined threshold value, which is more than the 3rd predetermined threshold value, if it is not, then by this sort after bank of queues In next application queue as queue to be updated, using the difference as total quantity, and return and perform above-mentioned steps 208, if so, Following step 210 can then be performed.
For example, the 3rd predetermined threshold value can be 800, due to deleting Queue5 handover information in rear application queue storehouse Total quantity SUM is changed into 1005-9=996 > 800, therefore, also to continue to choose the Queue2 of ranking second from application queue storehouse Continue to delete, the destination number deleted at this time is N2*10%, afterwards, continues to calculate the total quantity SUM after deleting, so Circulation, until SUM≤800 when terminate.
210th, the first electronic equipment obtains synchronous store instruction, and obtains the application queue storehouse according to the synchronization store instruction In application identities.
For example, Fig. 4 is referred to, the first electronic equipment can set a timer, which can be small every one When just trigger generate the synchronization store instruction, it is of course also possible to be shut down when automatically generate the synchronization store instruction.
211st, the application identities are encrypted in the first electronic equipment, obtain encryption identification, and will according to the encryption identification Handover information in respective application queue is stored in the second electronic equipment.
For example, { App1, App2 ... Appx } can be encrypted by AES encryption algorithm, obtains encryption identification, and can Encryption identification is being write External memory equipment and then write-in carriage return as row segmentation, the then corresponding application of write-in successively Handover information in queue, after writing same write-in carriage return split as row, then start to write next encryption identification and its Corresponding handover information, until all encryption identifications and handover information write-in finish.
212nd, the first electronic equipment obtains power-on instruction, and is obtained and added from second electronic equipment according to the power-on instruction Secret mark knows and the corresponding handover information of the encryption identification.
213rd, the encryption identification is decrypted in the first electronic equipment, obtains the application identities, and according to the application identities The application queue storehouse is established with corresponding handover information.
For example, the first electronic equipment can actively obtain storage content, Ran Houtong in start from External memory equipment Cross decryption and data structure rebuilds and restores hashmap.
