Decrypting the encrypted identifier to obtain the application identifier;

And establishing the application queue library according to the application identifier and corresponding switching information.

As shown in FIG. 1, the specific process of the information storage method can be as follows:

101. Acquire application information to be stored, where the application information includes target application identifier and target switching information.

In this embodiment, the application identifier (or target application identifier) is a unique identifier of the application, which may be an application name. The switching information (or the target switching information) mainly refers to related information when the application switches to the foreground, such as the switching time, the last foreground application that is switched, and the like.

102. Determine, according to the target application identifier, a first target queue from the stored application queue library, where the application queue library includes at least one application queue, and each application queue includes at least one switching information.

In this embodiment, the application queue library is used to store switching information of all applications that have been switched to the foreground in the historical period, and each switching information is stored in the corresponding application queue in the order of switching time, and the application queue may be It is a FIFO (First Input First Output) queue, which is a FIFO data structure, which can only sequentially write switching information and sequentially read switching information.

For example, the application queue library further includes at least one application identifier, and each application identifier corresponds to one application queue. In this case, the foregoing step 102 may specifically include:

Matching the target application identifier with the application identifier;

In this embodiment, the application queue and the application identifier stored in the application queue library are stored in association. For example, the application identifier may be used as a key, and the application queue is associated with the value of the key. The electronic device can establish an application queue for each application in advance, or can establish a corresponding application queue when the application is first started. If the application queue is created when the application is started for the first time, if there is no application queue of the current foreground application in the application queue, an empty first-in first-out queue can be established according to the application identifier of the current foreground application, as the application queue of the current foreground application.

103. Update the first target queue according to the target switching information to store the application information in the application queue library.

For example, the foregoing step 103 may specifically include:

Storing the target switching information at the end of the first target queue;

In this embodiment, for the first-in first-out application queue, each time the new switching information is acquired, the new switching information may be stored at the end of the corresponding application queue. The first preset threshold may be determined according to the actual memory size. The larger the actual memory, the larger the first preset threshold may be. For example, the first preset threshold may be 100. The preset number can be an artificially set value, such as 5. Generally, since the frequency of high frequency application (referred to as high frequency application) is switched to the foreground more frequently, the switching information stored in the corresponding application queue should also be more (that is, the queue length is longer), in order to avoid high frequency application. Excessive switching information occupies system memory, resulting in insufficient memory to store switching information of low frequency applications, and can limit the maximum length of each application queue (first preset threshold), that is, whenever there is new switching information storage When the corresponding application queue is used, it can detect whether the length of the application queue exceeds the maximum length. If it exceeds, the data is deleted. Considering that the data reference value is longer than the current time, the storage time can be the longest ( That is, single or partial switching information that is listed in front of the application queue is deleted.

104. Update the application queue library according to the updated first target queue.

For example, the foregoing step 104 may specifically include:

Sorting the application queues in the application queue library according to the second quantity from the largest to the smallest, obtaining the sorted queue library, and calculating the total quantity according to the second quantity;

The sorted queue library is updated according to the total number.

In this embodiment, since the application queue library is usually stored in the system memory of the electronic device, in order to avoid excessive use of the memory space, the data amount may be controlled within a certain scale, that is, each time a new switching information is stored, It is necessary to detect the total amount of switching information in the application queue library, and according to the total amount, it is determined that data deletion is not required.

For example, the foregoing step of “updating the sorted queue library according to the total quantity” may specifically include:

The previous target quantity bar switching information in the queue to be updated is deleted to update the to-be-updated queue.

In this embodiment, the second preset threshold and the preset ratio may be manually set. For example, the second preset threshold may be 1000, and the preset ratio may be 10%. When the total amount of the switching information in the application queue library exceeds the second preset threshold, the switching information of the application may be sequentially deleted according to the frequency of use from the highest to the lowest. When the first deletion is performed, the queue after the sorting is usually selected. The first application queue in the middle.

Further, after deleting the previous target quantity strip switching information in the queue to be updated, the information storage method may further include:

If yes, the next application queue in the sorted queue library is used as the queue to be updated, and the difference is taken as the total quantity, and the operation of obtaining the second quantity corresponding to the queue to be updated is performed until all application queues are updated. .

In this embodiment, the third preset threshold may be an optimal storage amount manually set, such as 800. After the single application queue is deleted, the total amount of switching information in the application queue library changes. If the total amount of detection exceeds the optimal storage amount, the next application queue needs to be selected for deletion. Decrease until the total amount is less than or equal to the optimal storage amount.

In addition, since the general electronic device has a power-down protection strategy, that is, the data stored in the system memory is automatically cleared in the case of power failure, in order to avoid data loss stored in the application queue library after the power failure, it may be periodically Synchronizing the information to the external storage device, that is, after the above step 104, the information storage method may further include:

Obtaining a synchronous storage instruction;

Encrypting the application identifier to obtain an encrypted identifier;

In this embodiment, the synchronous storage instruction may be automatically generated after the shutdown or the specified time is reached. Specifically, the electronic device may set a timer, and the timer may be shut down at a certain time (such as one hour) or received. The information triggers the generation of the synchronous store instruction. The encryption method may be determined according to actual needs, such as AES (Advanced Encryption Standard), which is a symmetric encryption algorithm, that is, encrypting and decrypting data using the same key. The second electronic device mainly refers to an external storage device, such as a storage server or a hard disk.

It should be emphasized that, because the switching information of the application is related to the user's usage habits, in order to prevent the external storage device from leaking the user's privacy when it is lost or stolen, the application identifier may be encrypted in the synchronous storage process, of course, due to the first in first out. The queue has a certain data structure. To avoid garbled characters in the storage process, the encryption identifier and the switching information can be stored only in the external storage device. Specifically, the electronic device can write the encrypted identifier to the external storage device and then write it back. The car is divided into rows, and then written to the switching information in the corresponding application queue. After writing, the carriage return is also written as the line division, and then the next encryption identifier and its corresponding switching information are written, until all the encryption identifiers and switching are performed. The information has been written.

It is easy to understand that since the data in the system memory is cleared after each power failure, the electronic device can automatically synchronize the data in the external storage storage device into the memory after booting, so as to be subsequently queried and used, that is, After the switching information in the corresponding application queue is stored in the second electronic device according to the encrypted identifier, the information storage method may further include:

Obtain a boot command;

And acquiring, according to the booting instruction, the encrypted identifier and the switching information corresponding to the encrypted identifier from the second electronic device;

Decrypting the encrypted identifier to obtain the application identifier;

The application queue library is established according to the application identifier and the corresponding switching information.

In this embodiment, for the AES encryption algorithm, the same key can be used to decrypt the encrypted identifier, and the application identifier is restored, and then an empty first in first out queue corresponding to the application identifier can be established first, and the empty first ingress is created. The switching information corresponding to the encrypted identifier is sequentially written in the first-out queue, thereby restoring the application queue.

The information storage method provided in this embodiment is applied to the first electronic device, and the application information includes the target application identifier and the target switching information, and the target application identifier is stored according to the target application identifier. Determining a first target queue in the application queue library, the application queue library includes at least one application queue, each application queue includes at least one switching information, and then updating the first target queue according to the target switching information, in the application queue The application information is stored in the library, and the application queue library is updated according to the updated first target queue, so that in the storage process of the application information, not only the system memory consumption can be reduced, but also the data is comprehensively ensured. Sex, simple method, good storage effect.

In this embodiment, the information storage device is specifically integrated into the first electronic device as an example for detailed description.

Referring to FIG. 2, an information storage method may be as follows:

201. The first electronic device acquires application information to be stored, where the application information includes a target application identifier and target switching information.

For example, the application running in the foreground can be monitored in real time. When the application running in the foreground is changed, the application identifier of the changed running application, the application identifier of the running application before the change, and the changed time are used as the application information to be stored.

The first electronic device matches the target application identifier with the application identifier in the stored application queue library. If the matching is successful, the application queue corresponding to the successfully matched application identifier is used as the first target queue, and the matching fails. And storing the target application identifier in the application queue library, and creating an empty application queue corresponding to the target application identifier, as the first target queue.

For example, referring to FIG. 3, when the user starts an app, the switch information corresponding to the App can be established in the electronic device through a hashmap, where the key is the app name and the value is a first-in, first-out FiFo. (first in, first out) queue, each FiFo queue corresponds to the switching information of the corresponding app. For example, the application identifier stored in the application queue library may include {App1, App2...Appx}, and the target application identifier may be Appi. In this case, the hashmap may be queried according to i, if i∈(1, 2...x), then If the match is successful, the matching application queue is the application queue corresponding to Appi.

If the match fails, you need to create a FiFo queue corresponding to Appi.

203. The first electronic device stores the target switching information at the tail of the first target queue, and when the target switching information is successfully added, the number of the switching information in the first target queue is counted as the first quantity.

204. The first electronic device determines whether the first quantity is greater than a first preset threshold, and if yes, deleting the preset number of switching information in the first target queue, if not, directly Perform the following step 205.

For example, the first preset threshold (QueueMax) may be 100, the preset number of entries may be 1, and the application queue corresponding to Appi is Queuei, and the Queuei may include Ni strip switching information, such as Appi_1, Appi_2, ... Appi_Ni, When the switching information stored in the FIFO queue corresponding to Appi exceeds 100, that is, Ni>100, the switching information Appi_1 needs to be deleted.

205. The first electronic device collects the number of switching information in each application queue as the second quantity, and sorts the application queues in the application queue library according to the second quantity in descending order, and obtains the sorted queue. The library, after which the total quantity is calculated based on the second quantity.

For example, if the application queue library includes X application queues of {Queue1, Queue2...QueueX}, and the second number of switching information in each application queue may be {N1, N2... NX}, then The second number of values corresponding to each application queue sorts them. The more switching information, the higher the ranking, the less the switching information, the lower the ranking, for example, the sorted application queue library can be Queue5, Queue2...QueueX-1.

206. The first electronic device determines whether the total quantity is greater than a second preset threshold. If yes, performing the following step 207. If not, performing the following step 210.

207. The first electronic device selects the top-ranked application queue in the sorted queue library as the queue to be updated, and obtains the second quantity corresponding to the queue to be updated.

208. The first electronic device determines the target quantity according to the preset ratio and the second quantity corresponding to the to-be-updated queue, and deletes the previous target quantity quantity switching information in the to-be-updated queue to update the to-be-updated queue.

For example, the second preset threshold may be 1000, and the preset ratio may be 10%. The sum SUM of N1, N2...Nx can be calculated. If SUM is greater than 1000, such as 1005, the first queue Queue5 can be obtained. If the second number N5 of the switching information in Queue5 is 90, the target quantity is 90*10%=9, that is, the first 9 pieces of switching information are selected for deletion.

209. The first electronic device calculates a difference between the current total quantity and the target quantity, and determines whether the difference is less than or equal to a third preset threshold. The second preset threshold is greater than a third preset threshold. Then, the next application queue in the sorted queue library is used as the queue to be updated, and the difference is taken as the total number, and the above step 208 is performed, and if so, the following step 210 can be performed.

For example, the third preset threshold may be 800. Since the total number of switching information in the application queue library after the Queue 5 is deleted is changed to 1005-9=996>800, the row is still selected from the application queue library. The second Queue2 continues to be deleted. At this time, the number of targets to be deleted is N2*10%. Thereafter, the total number SUM after the deletion is continued, and the loop is repeated until SUM ≤ 800.

210. The first electronic device acquires a synchronous storage instruction, and acquires an application identifier in the application queue library according to the synchronous storage instruction.

For example, referring to FIG. 4, the first electronic device may set a timer, which may trigger the generation of the synchronous storage instruction every hour. Of course, the synchronous storage instruction may be automatically generated when the power is turned off.

211. The first electronic device encrypts the application identifier, obtains an encrypted identifier, and stores the switching information in the corresponding application queue in the second electronic device according to the encrypted identifier.

For example, {App1, App2...Appx} can be encrypted by the AES encryption algorithm to obtain an encrypted identifier, and after the encrypted identifier is written to the external storage device, the carriage return is written as a line division, and then the corresponding application is sequentially written. The switching information in the queue is also written to the carriage return as a line division after writing, and then the next encryption identifier and its corresponding switching information are written until all the encryption identifiers and switching information are written.

212. The first electronic device obtains a booting instruction, and obtains an encrypted identifier and a switching information corresponding to the encrypted identifier from the second electronic device according to the booting instruction.

213. The first electronic device decrypts the encrypted identifier, obtains the application identifier, and establishes the application queue library according to the application identifier and the corresponding switching information.

For example, the first electronic device can actively obtain the stored content from the external storage device when the device is powered on, and then restore the hashmap through decryption and data structure reconstruction.

The information storage method provided in this embodiment, wherein the first electronic device can acquire the application information to be stored, the application information includes the target application identifier and the target switching information, and the target application identifier and the stored application queue are The application identifier in the library is matched. If the matching is successful, the application queue corresponding to the successfully matched application identifier is used as the first target queue. If the matching fails, the target application identifier is stored in the application queue library, and a An empty application queue corresponding to the target application identifier is used as the first target queue, and then the target switching information is stored at the tail of the first target queue, and when the target switching information is successfully added, the first target queue is counted. The number of the information to be switched is the first quantity. Then, it is determined whether the first quantity is greater than the first preset threshold. If yes, the preset number of the last number of the first target queue is deleted. If not, the number of switching information in each application queue is counted as the second quantity, and according to the second Sorting the application queues in the application queue library from the largest to the smallest, obtaining the sorted queue library, and then calculating the total quantity according to the second quantity, and then determining whether the total quantity is greater than a second preset threshold, if Then, the application queue of the highest ranked queue in the queued queue is selected as the queue to be updated, and the second quantity corresponding to the queue to be updated is obtained, and then, according to the preset ratio and the second corresponding to the queue to be updated The quantity determines the target quantity, and deletes the previous target quantity bar switching information in the queue to be updated to update the to-be-updated queue, and then calculates the current difference between the total quantity and the target quantity, and determines whether the difference is The second preset threshold is greater than or equal to the third preset threshold, and the second preset threshold is greater than the third preset threshold. If yes, the next application queue in the sorted queue library is used as the queue to be updated, and the difference is taken as the total number. And returning to perform an operation of determining whether the total quantity is greater than a second preset threshold, so that not only the system memory usage can be reduced in the storage process of the application information, The data can be comprehensively ensured, the method is simple, and the storage effect is good. After that, the first electronic device can acquire the synchronous storage instruction, and obtain the application identifier in the application queue library according to the synchronous storage instruction, and then apply the application. The identifier is encrypted, and the encrypted identifier is obtained, and the switching information in the corresponding application queue is stored in the second electronic device according to the encrypted identifier, so that the data backup operation can be completed well, and the power-down protection strategy is avoided. After the data is lost due to the power failure, the first electronic device can obtain the power-on command, and obtain the encrypted identifier and the switching information corresponding to the encrypted identifier from the second electronic device according to the power-on command, and then perform the encrypted identifier. Decrypting, obtaining the application identifier, and establishing the application queue library according to the application identifier and the corresponding switching information, so that the lost data can be effectively restored after the power is cut off, and the reliability is high.
