Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The embodiment of the application provides an information storage method, an information storage device, a storage medium and electronic equipment.
An information storage method is applied to first electronic equipment and comprises the following steps: acquiring application information to be stored, wherein the application information comprises a target application identifier and target switching information; determining a first target queue from a stored application queue library according to the target application identifier, wherein the application queue library comprises at least one application queue, and each application queue comprises at least one piece of switching information; updating the first target queue according to the target switching information so as to store the application information in the application queue library; and updating the application queue library according to the updated first target queue.
As shown in fig. 1, the specific flow of the information storage method may be as follows:
101. and acquiring application information to be stored, wherein the application information comprises a target application identifier and target switching information.
In this embodiment, the application identifier (or the target application identifier) is a unique identifier of the application program, which may be an application name. The switching information (or target switching information) mainly refers to relevant information when the application switches to the foreground, such as the switching time, the last foreground application being switched, and the like.
102. A first target queue is determined from a stored application queue library according to the target application identification, the application queue library comprises at least one application queue, and each application queue comprises at least one piece of switching information.
In this embodiment, the application queue library is configured to store switching information of all applications that have been switched to a foreground in a historical period, each switching information is stored in a corresponding application queue according to a sequence of switching time, and the application queue may be a First Input First Output (FIFO) queue, which is a First in First out data structure and can only write the switching information in sequence and read the switching information in sequence.
For example, the application queue library further includes at least one application identifier, where each application identifier corresponds to one application queue, and at this time, the step 102 may specifically include:
matching the target application identification with the application identification;
if the matching is successful, taking an application queue corresponding to the successfully matched application identifier as a first target queue;
and if the matching fails, storing the target application identifier in the application queue library, and creating an empty application queue corresponding to the target application identifier as a first target queue.
In this embodiment, the application queue and the application identifier stored in the application queue library are stored in an associated manner, for example, the application identifier may be used as a Key (Key), and the application queue may be used as a Value (Value) of the Key to be associated. The electronic device may establish an application queue for each application in advance, or may establish a corresponding application queue only when the application is first started. When the application is started for the first time to create the corresponding application queue, if the application queue of the current foreground application does not exist in the application queue library, an empty first-in first-out queue can be created according to the application identifier of the current foreground application and used as the application queue of the current foreground application.
103. And updating the first target queue according to the target switching information so as to store the application information in the application queue library.
For example, the step 103 may specifically include:
storing the target switching information at the tail of the first target queue;
when the target switching information is successfully added, counting the number of the switching information in the first target queue as a first number;
judging whether the first quantity is larger than a first preset threshold value or not;
if yes, deleting the preset number switching information with the top rank in the first target queue.
In this embodiment, for the first-in first-out application queue, each time 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 an actual memory size, and the larger the actual memory is, the larger the first preset threshold may be, for example, the first preset threshold may be 100. The predetermined number may be a value set manually, such as 5. Generally, because the number of times of switching from a high-frequency application (referred to as a high-frequency application) to a foreground is large, the number of switching information stored in the corresponding application queue is large (that is, the queue length is long), in order to avoid that the switching information of the high-frequency application occupies too much system memory, so that insufficient memory is not available to store the switching information of the low-frequency application, the maximum length (a first preset threshold) of each application queue may be defined, that is, each time new switching information is stored in the corresponding application queue, whether the length of the application queue exceeds the maximum length may be detected, if the length exceeds the maximum length, data deletion may be performed, and considering that the reference value of data farther from the current time is lower, the single or part of the switching information with the longest storage time (that is, arranged in front of the application queue) may be deleted.
104. And updating the application queue library according to the updated first target queue.
For example, the step 104 may specifically include:
counting the number of switching information in each application queue as a second number;
sequencing the application queues in the application queue library according to the sequence of the second number from large to small to obtain a sequenced queue library, and calculating the total number according to the second number;
and updating the sorted queue library according to the total quantity.
In this embodiment, since the application queue library is usually stored in a system memory of the electronic device, in order to avoid occupying too much memory space, the data amount may be controlled within a certain scale, that is, each time new switching information is stored, the total amount of the switching information in the application queue library needs to be detected, and it is determined that data deletion is not needed according to the total amount.
For example, the step "updating the sorted queue library according to the total amount" may specifically include:
judging whether the total number is larger than a second preset threshold value;
if so, selecting the application queue with the top rank in the queue library after the sorting as the queue to be updated;
acquiring a second quantity corresponding to the queue to be updated, and determining a target quantity according to a preset proportion and the second quantity corresponding to the queue to be updated;
deleting the previous target number of switching information in the queue to be updated so as to update the queue to be updated.
In this embodiment, the second preset threshold and the preset ratio may be set manually, 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 a second preset threshold, the application switching information can be deleted in sequence from high to low in use frequency, and when the application switching information is deleted for the first time, the application queue which is the first bit in the sorted queue library is usually selected.
Further, after deleting the previous target number of pieces of switching information in the queue to be updated, the information storage method may further include:
calculating a difference between the current total number and the target number;
judging whether the difference value is smaller than or equal to a third preset threshold value, wherein the second preset threshold value is larger than the third preset threshold value;
if so, taking the next application queue in the sorted queue library as a queue to be updated, taking the difference value as the total number, and returning to execute the operation of obtaining the second number corresponding to the queue to be updated until all the application queues are updated.
In this embodiment, the third preset threshold may be an optimal storage amount, such as 800, set by a human. When a single application queue is deleted each time, the total amount of switching information in the application queue library changes, and if the detected total amount exceeds the optimal storage amount each time, the next application queue needs to be continuously selected for deletion until the total amount is less than or equal to the optimal storage amount.
In addition, since general electronic devices all have a power-down protection policy, that is, data stored in the system memory is automatically cleared when power is off, in order to avoid that data stored in the application queue library is lost after power is off, the data may be periodically synchronized to an external storage device, that is, after step 104, the information storage method may further include:
acquiring a synchronous storage instruction;
acquiring an application identifier in the application queue library according to the synchronous storage instruction;
encrypting the application identifier to obtain an encrypted identifier;
and storing the switching information in the corresponding application queue in the second electronic equipment according to the encrypted identifier.
In this embodiment, the synchronous storage instruction may be automatically generated after shutdown or reaching a specified time, and specifically, the electronic device may set a timer, and the timer may trigger generation of the synchronous storage instruction every certain time period (for example, one hour) or when shutdown information is received. The Encryption method may be determined according to actual requirements, and may be, for example, AES (Advanced Encryption Standard), which is a symmetric Encryption algorithm, that is, data is encrypted and decrypted 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, since the switching information of the application is related to the usage habit of the user, in order to avoid the external storage device from revealing the privacy of the user when the external storage device is lost or stolen, the application identifier may be encrypted in the synchronous storage process, of course, since the first-in first-out queue has a certain data structure, in order to avoid the messy code in the storage process, the encryption identifier and the switching information may be stored only in the external storage device, specifically, the electronic device may write the encryption identifier into the external storage device, then write the carriage back as row division, then write the switching information in the corresponding application queue in sequence, after writing, write the carriage back as row division, then start to write the next encryption identifier and the switching information corresponding thereto until all the encryption identifiers and the switching information are written completely.
It is easy to understand that, since the data in the system memory is cleared after each power-off, the electronic device may automatically synchronize the data in the external storage device into the memory after starting up, so as to facilitate subsequent query and use, that is, after the switching information in the corresponding application queue is stored in the second electronic device according to the encryption identifier, the information storage method may further include:
acquiring a starting-up instruction;
acquiring an encryption identifier and switching information corresponding to the encryption identifier from the second electronic equipment according to the starting instruction;
decrypting the encrypted identifier to obtain the application identifier;
and establishing the application queue library according to the application identification and the corresponding switching information.
In this embodiment, for the AES encryption algorithm, the same key may be used to decrypt the encrypted identifier and restore the encrypted identifier to obtain the application identifier, and then an empty first-in first-out queue corresponding to the application identifier may be first established, and the switching information corresponding to the encrypted identifier is sequentially written into the empty first-in first-out queue, so that the application queue is restored and obtained.
As can be seen from the above, the information storage method provided in this embodiment is applied to a first electronic device, and is implemented by obtaining application information to be stored, where the application information includes a target application identifier and target switching information, determining a first target queue from a stored application queue library according to the target application identifier, where the application queue library includes at least one application queue, and each application queue includes at least one piece of switching information, and then updating the first target queue according to the target switching information to store the application information in the application queue library, and updating the application queue library according to the updated first target queue, so that in a storage process of the application information, not only can an occupied amount of a system memory be reduced, but also a comprehensiveness of data can be better ensured, and the method is simple and has a good storage effect.
In the present embodiment, a detailed description will be given taking an example in which the information storage apparatus is specifically integrated in the first electronic device.
Referring to fig. 2, a specific flow of an information storage method may be as follows:
201. the first electronic equipment acquires application information to be stored, wherein the application information comprises a target application identifier and target switching information.
For example, foreground running applications may be monitored in real time, and when a change of the foreground running application is found, the application identifier of the running application after the change, the application identifier of the running application before the change, and the change time may be used as the application information to be stored.
202. And the first electronic equipment matches the target application identifier with the application identifiers in the stored application queue library, if the matching is successful, the application queue corresponding to the successfully matched application identifier is used as a first target queue, if the matching is failed, the target application identifier is stored in the application queue library, and an empty application queue corresponding to the target application identifier is created and used as the first target queue.
For example, referring to fig. 3, when a user starts a certain App, the switching information corresponding to the App may be established in the electronic device through hashmap (hash mapping), where key is an App application name, value is a first-in-first-out FiFo (first-in-first-out) queue, and each FiFo queue corresponds to the switching information of the corresponding App
Indicating that the matching fails, and needing to create a FiFo queue corresponding to the api.
203. The first electronic device stores the target switching information at the tail of the first target queue, and counts the number of the switching information in the first target queue as a first number when the target switching information is successfully added.
204. The first electronic device determines whether the first number is greater than a first preset threshold, if so, deletes the preset number switching information with the top rank in the first target queue, otherwise, directly performs the following step 205.
For example, the first preset threshold (QueueMax) may be 100, the preset number may be 1, the application queue corresponding to api is Queuei, the Queuei may include Ni pieces of switching information, such as api _1 and api _2.
205. The first electronic device counts the number of switching information in each application queue as a second number, sorts the application queues in the application queue library according to the sequence of the second number from large to small to obtain a sorted queue library, and then calculates the total number according to the second number.
For example, if the application Queue library includes X application queues { Queue1, Queue2.. QueueX }, and the second number of switching information in each application Queue may be { N1, N2.. NX }, in turn, the application queues may be sorted according to the second number of values corresponding to each application Queue, the more switching information, the earlier the ranking, the less switching information, and the later the ranking, for example, the application Queue library after sorting may be Queue5, Queue2.. QueueX-1.
206. The first electronic device determines whether the total number is greater than a second preset threshold, if so, the following step 207 is executed, and if not, the following step 210 may be executed.
207. And the first electronic equipment selects the application queue with the top rank in the queue library after the sorting as the queue to be updated and acquires the second quantity corresponding to the queue to be updated.
208. And the first electronic equipment determines the target quantity according to a preset proportion and the second quantity corresponding to the queue to be updated, and deletes the switching information of the previous target quantity in the queue to be updated so as to update the queue to be updated.
For example, the second predetermined threshold may be 1000, and the predetermined ratio may be 10%. SUM of N1, N2.. Nx may be calculated, if SUM is greater than 1000, for example, 1005, a Queue5 with the first rank may be obtained, and if the second number N5 of switching information in Queue5 is 90, the target number is 90 × 10% to 9, that is, the first 9 pieces of switching information are selected for deletion.
209. And the first electronic device calculates a difference value between the current total number and the target number, and judges whether the difference value is smaller than or equal to a third preset threshold value, wherein the second preset threshold value is larger than the third preset threshold value, if not, the next application queue in the sorted queue library is used as a queue to be updated, the difference value is used as the total number, the step 208 is returned to be executed, and if yes, the following step 210 can be executed.
For example, the third preset threshold may be 800, since the total number SUM of the switching information in the application Queue library after the deletion of Queue5 is changed to 1005-9 ═ 996 > 800, the second Queue2 in the application Queue library is continuously selected for deletion, and the target number of deletions is N2 × 10%, and then the total number SUM after the deletion is continuously calculated, and the process is repeated until the SUM is less than or equal to 800.
210. And the first electronic equipment acquires the synchronous storage instruction and acquires the 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, and the timer may trigger generation of the synchronous storage instruction every hour, or may automatically generate the synchronous storage instruction when the electronic device is powered off.
211. The first electronic device encrypts the application identifier to obtain 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 } may be encrypted by AES encryption algorithm to obtain an encrypted identifier, and after the encrypted identifier is written into the external storage device, it is written back as line partition, then the switching information in the corresponding application queue is written in sequence, after writing, it is also written back as line partition, and then the next encrypted identifier and its corresponding switching information are written in until all encrypted identifiers and switching information are written in.
212. The first electronic device obtains a starting-up instruction, and obtains an encryption identifier and switching information corresponding to the encryption identifier from the second electronic device according to the starting-up instruction.
213. The first electronic equipment decrypts the encrypted identifier to obtain 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 may actively obtain the storage content from the external storage device at the time of booting, and then restore the hashmap by decryption and data structure reconstruction.
As can be seen from the above, in the information storage method provided in this embodiment, the first electronic device may obtain application information to be stored, where the application information includes a target application identifier and target switching information, match the target application identifier with an application identifier in a stored application queue library, if the matching is successful, use an application queue corresponding to the successfully matched application identifier as a first target queue, if the matching is unsuccessful, store the target application identifier in the application queue library, create an empty application queue corresponding to the target application identifier as a first target queue, then store the target switching information at a tail of the first target queue, and when the target switching information is successfully added, count the number of switching information in the first target queue as a first number, then determine whether the first number is greater than a first preset threshold, if so, deleting the preset number switching information with the highest ranking in the first target queue, if not, counting the number of the switching information in each application queue as a second number, sequencing the application queues in the application queue library according to the sequence of the second number from large to small to obtain a sequenced queue library, then calculating the total number according to the second number, then judging whether the total number is greater than a second preset threshold value, if so, selecting the application queue with the highest ranking in the sequenced queue library as a queue to be updated, obtaining the second number corresponding to the queue to be updated, then determining the target number according to a preset proportion and the second number corresponding to the queue to be updated, deleting the previous target number switching information in the queue to be updated to update the queue to be updated, and then calculating the difference value between the current total number and the target number, and judging whether the difference is less than or equal to a third preset threshold, the second preset threshold is greater than the third preset threshold, if so, taking the next application queue in the sorted queue library as a queue to be updated, taking the difference as the total amount, and returning to execute the operation of judging whether the total amount is greater than the second preset threshold, so that in the storage process of the application information, not only can the occupation amount of a system memory be reduced, but also the comprehensiveness of data can be better ensured, the method is simple, the storage effect is good, then, the first electronic device can obtain a synchronous storage instruction, obtain an application identifier in the application queue library according to the synchronous storage instruction, then encrypt the application identifier to obtain an encrypted identifier, and store the switching information in the corresponding application queue in the second electronic device according to the encrypted identifier, so that the backup operation of the data can be better completed, the method has a certain power-down protection strategy, avoids data loss caused by power failure, and is high in reliability.
According to the method described in the above embodiments, the present embodiment will be further described from the perspective of an information storage device, which may be specifically implemented as a stand-alone entity, or may be implemented by being integrated in an electronic device, such as a terminal, which may include a mobile phone, a tablet computer, a personal computer, and the like.

if yes, deleting the preset number switching information with the top rank in the first target queue.
In this embodiment, for the first-in first-out application queue, each time 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 an actual memory size, and the larger the actual memory is, the larger the first preset threshold may be, for example, the first preset threshold may be 100. The predetermined number may be a value set manually, such as 5. Generally, because the number of times of switching from a high-frequency application (referred to as a high-frequency application) to a foreground is large, the number of switching information stored in the corresponding application queue is large (that is, the queue length is long), in order to avoid that the switching information of the high-frequency application occupies too much system memory, so that insufficient memory is not available to store the switching information of the low-frequency application, the maximum length (a first preset threshold) of each application queue may be defined, that is, each time new switching information is stored in the corresponding application queue, whether the length of the application queue exceeds the maximum length may be detected, if the length exceeds the maximum length, data deletion may be performed, and considering that the reference value of data farther from the current time is lower, the single or part of the switching information with the longest storage time (that is, arranged in front of the application queue) may be deleted.
(4) Second update module 40
And the second updating module 40 is configured to update the application queue library according to the updated first target queue.
For example, referring to fig. 6, the second updating module 40 may specifically include a statistics sub-module 41, a ranking sub-module 42, and an updating sub-module 43, where:
a counting submodule 41, configured to count the number of switching information in each application queue as a second number;
the sorting submodule 42 is configured to sort the application queues in the application queue library according to the sequence from the largest to the smallest of the second number to obtain a sorted queue library, and calculate the total number according to the second number;
and an updating submodule 43, configured to update the sorted queue library according to the total number.
In this embodiment, since the application queue library is usually stored in a system memory of the electronic device, in order to avoid occupying too much memory space, the data amount may be controlled within a certain scale, that is, each time new switching information is stored, the total amount of the switching information in the application queue library needs to be detected, and it is determined that data deletion is not needed according to the total amount.
For example, the update submodule 43 may be specifically configured to:
judging whether the total number is larger than a second preset threshold value;
if so, selecting the application queue with the top rank in the queue library after the sorting as the queue to be updated;
acquiring a second quantity corresponding to the queue to be updated, and determining a target quantity according to a preset proportion and the second quantity corresponding to the queue to be updated;
deleting the previous target number of switching information in the queue to be updated so as to update the queue to be updated.
In this embodiment, the second preset threshold and the preset ratio may be set manually, 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 a second preset threshold, the application switching information can be deleted in sequence from high to low in use frequency, and when the application switching information is deleted for the first time, the application queue which is the first bit in the sorted queue library is usually selected.
Further, after deleting the previous target number of pieces of switching information in the queue to be updated, the updating sub-module 43 may further be configured to:
calculating a difference between the current total number and the target number;
judging whether the difference value is smaller than or equal to a third preset threshold value, wherein the second preset threshold value is larger than the third preset threshold value;
if so, taking the next application queue in the sorted queue library as a queue to be updated, taking the difference value as the total number, and returning to execute the operation of obtaining the second number corresponding to the queue to be updated until all the application queues are updated.
In this embodiment, the third preset threshold may be an optimal storage amount, such as 800, set by a human. When a single application queue is deleted each time, the total amount of switching information in the application queue library changes, and if the detected total amount exceeds the optimal storage amount each time, the next application queue needs to be continuously selected for deletion until the total amount is less than or equal to the optimal storage amount.
In addition, since general electronic devices all have a power-down protection policy, that is, data stored in the system memory is automatically cleared when power is off, in order to avoid that the data stored in the application queue library is lost after power is off, the data may be periodically synchronized to an external storage device, that is, referring to fig. 7, the information storage apparatus may further include a synchronization module 50 configured to:
after the second updating module 40 updates the application queue library according to the updated first target queue, a synchronous storage instruction is acquired;
acquiring an application identifier in the application queue library according to the synchronous storage instruction;
encrypting the application identifier to obtain an encrypted identifier;
and storing the switching information in the corresponding application queue in the second electronic equipment according to the encrypted identifier.
In this embodiment, the synchronous storage instruction may be automatically generated after shutdown or reaching a specified time, and specifically, the electronic device may set a timer, and the timer may trigger generation of the synchronous storage instruction every certain time period (for example, one hour) or when shutdown information is received. The Encryption method may be determined according to actual requirements, and may be, for example, AES (Advanced Encryption Standard), which is a symmetric Encryption algorithm, that is, data is encrypted and decrypted 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, since the switching information of the application is related to the usage habit of the user, in order to avoid the external storage device from revealing the privacy of the user when the external storage device is lost or stolen, the application identifier may be encrypted in the synchronous storage process, of course, since the first-in first-out queue has a certain data structure, in order to avoid the messy code in the storage process, the encryption identifier and the switching information may be stored only in the external storage device, specifically, the electronic device may write the encryption identifier into the external storage device, then write the carriage back as row division, then write the switching information in the corresponding application queue in sequence, after writing, write the carriage back as row division, then start to write the next encryption identifier and the switching information corresponding thereto until all the encryption identifiers and the switching information are written completely.
It is easy to understand that, since the data in the system memory is cleared after each power-off, the electronic device may automatically synchronize the data in the external storage device to the memory after the electronic device is powered on, so as to facilitate subsequent query and use, that is, the information storage apparatus may further include a second obtaining module 60, configured to:
after the synchronization module 50 stores the switching information in the corresponding application queue in the second electronic device according to the encrypted identifier, acquiring a power-on instruction;
acquiring an encryption identifier and switching information corresponding to the encryption identifier from the second electronic equipment according to the starting instruction;
decrypting the encrypted identifier to obtain the application identifier;
and establishing the application queue library according to the application identification and the corresponding switching information.
In this embodiment, for the AES encryption algorithm, the same key may be used to decrypt the encrypted identifier and restore the encrypted identifier to obtain the application identifier, and then an empty first-in first-out queue corresponding to the application identifier may be first established, and the switching information corresponding to the encrypted identifier is sequentially written into the empty first-in first-out queue, so that the application queue is restored and obtained.
