[0020] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0021] Among them, in Android or other Linux-based operating systems, Swap is a traditional memory swap strategy. It allows the operating system to "swap out" the data in the memory to the hard disk (or other storage media) to free up memory space for other processes to use. When the "swapped out" data is needed again, the operating system will "swap it back" from the hard disk to the memory to achieve the purpose of using the data.

[0022] The following are the main mechanisms of Linux swap management:

[0023] 1. Swap Space: This is a special hard disk partition that is used by the operating system as a Swap storage space. The size of the Swap Space is generally set by the system administrator during system installation or configuration, and can usually be reasonably determined based on the system's RAM size and application requirements.

[0024] 2. Swapiness: This is a system parameter that controls the operating system's reliance on Swap. The value of Swapiness ranges from 0 to 100. A higher value indicates that the operating system is more inclined to swap data out to Swap Space, while a lower value indicates that the system is more inclined to keep data in memory as much as possible.

[0025] 3. Page Replacement Algorithm: Swap management in Linux systems is mainly based on a page replacement algorithm called "Least Recently Used" (LRU). Simply put, the LRU algorithm records the last time each memory page was accessed. When swapping is required, the system will select the page that has not been accessed for the longest time to swap out, because such a page is least likely to be needed again in the near future.

[0026] 4. Swap In & Swap Out: When the system memory is insufficient, Linux will trigger Swap Out to swap out the selected memory page to Swap Space. When a swapped out page is needed again, the system will trigger Swap In to swap the page from Swap Space back to the memory.

[0027] 5. Overcommit and OOM Killer: The Linux system allows memory "overcommit", that is, the total amount of memory requested by the application can exceed the sum of physical RAM and Swap Space. When the over-allocated memory is really needed, if there is not enough memory space, the system will trigger the "Out Of Memory Killer" (OOM Killer) process, automatically ending certain processes to free up memory space.

[0028] The inventors have found through research that although Swap can provide additional space when memory is insufficient, over-reliance on Swap may seriously affect system performance because the hard disk read and write speed is much lower than the random access memory (RAM). In addition, current memory management technology treats all applications equally without considering their impact on users; pages of important applications may be replaced inappropriately, affecting performance; there is a lack of differentiated memory management for different applications, and fine-grained memory management cannot be achieved; current memory management technology cannot dynamically adjust its memory management strategy according to the status of the application.

[0029] In view of the above problems, the inventors have discovered after long-term research and proposed the memory management method, device, electronic device and storage medium provided in the embodiments of the present application. The running applications are grouped by setting program grouping rules in the configuration file, and the memory exchange strategy set in the configuration file is used to manage the memory of the grouped applications, which can make the memory management more flexible and sophisticated. Among them, the specific memory management method is described in detail in the subsequent embodiments.

[0030] See also Figure 1 , Figure 1 The flowchart of the memory management method provided by an embodiment of the present application is shown. The method is used to group running applications by setting program grouping rules through a configuration file, and to manage the memory of the grouped applications through a memory exchange policy set in the configuration file, so that the memory management can be more flexible and sophisticated. In a specific embodiment, the memory management method is applied to Figure 8The memory management device 200 and the electronic device 100 ( Fig. 9 ). The following will take an electronic device as an example to illustrate the specific process of this embodiment. Of course, it can be understood that the electronic device used in this embodiment may include a smart phone, a tablet computer, a wearable electronic device, etc., which is not limited here. Figure 1 The process shown is described in detail, and the memory management method may specifically include the following steps:

[0031] Step S110: when the operating system of the electronic device is started, read a preset configuration file from the operating system.

[0032] In this embodiment, when the operating system of the electronic device is started, a preset configuration file can be read from the operating system of the electronic device. Optionally, the preset configuration file can specify program grouping rules and memory exchange strategies.

[0033] In some implementations, the electronic device may predefine a configuration file as a preset configuration file, and add the preset configuration file to the operating system of the electronic device. Accordingly, when the operating system of the electronic device is started, the preset configuration file may be read from the operating system.

[0034] As an implementable manner, when the electronic device adds a preset configuration file to the operating system of the electronic device, the location where the preset configuration file is added can be recorded. Based on this, when the operating system of the electronic device is started, the preset configuration file can be read from the operating system based on the location where the preset configuration file is added. For example, the path for obtaining the preset configuration file can be determined based on the location where the preset configuration file is added, and when the operating system of the electronic device is started, the preset configuration file can be read from the operating system based on the path.

[0035] In some implementations, it is possible to detect whether the operating system of the electronic device is started. If it is detected that the operating system of the electronic device is started, a preset configuration file can be read from the operating system of the electronic device; if it is detected that the operating system of the electronic device is not started, it is possible to continue to detect whether the operating system of the electronic device is started. As an implementable method, a listener can be registered in the electronic device, and the listener can be used to detect whether the operating system of the electronic device is started.

[0036] Step S120: parsing the preset configuration file to obtain program grouping rules and memory swap strategies.

[0037] In this embodiment, when a preset configuration file is read, the preset configuration file can be parsed to obtain a program grouping rule and a memory swap strategy Swap. The program grouping rule is used to indicate grouping of applications running on the electronic device, and the memory swap strategy is used to indicate swapping out or swapping in memory data for applications in different groups.

[0038] In some embodiments, when a preset configuration file is read, the preset configuration file can be parsed by a file parsing technique to obtain program grouping rules and memory exchange strategies. As an implementable manner, the electronic device can be pre-set with multiple file parsing techniques. When a preset configuration file is read, a target file parsing technique can be selected from multiple file parsing techniques based on the preset configuration file, and the preset configuration file can be parsed by the target file parsing technique to obtain program grouping rules and memory exchange strategies. Optionally, selecting a target file parsing technique from multiple file parsing techniques based on the preset configuration file may include: selecting a target file parsing technique from multiple file parsing techniques based on the format of the preset configuration file; selecting a target file parsing technique from multiple file parsing techniques based on the data volume of the preset configuration file, etc., which is not limited here.

[0039] In some implementations, the number of the program grouping rules may be one or more. The number of the memory swap policies may be one or more.

[0040] Step S130: Grouping the multiple application programs running on the electronic device based on the program grouping rule to obtain multiple program groups, wherein each of the multiple program groups includes at least one application program.

[0041] In this embodiment, when a program grouping rule is obtained, multiple application programs running on the electronic device can be grouped based on the program grouping rule to obtain multiple program groups. It can be understood that each of the multiple program groups includes at least one application program.

[0042] As an example, if the number of applications running on the electronic device is 5, the 5 applications can be grouped based on the program grouping rule to obtain multiple 3 program groups, where the first program group of the 3 program groups includes 2 applications, the second program group includes 2 applications, and the third program group includes 1 application.

[0043] In some implementations, when a program grouping rule is obtained, the application programs running on the electronic device can be detected, and the multiple application programs running on the detected electronic device can be grouped based on the program grouping rule to obtain multiple program groups. Optionally, the application programs running on the electronic device can include: an application program running in the foreground of the electronic device, an application program running in the background of the electronic device, an application program running in the foreground and background of the electronic device, etc., which is not limited here.

[0044] As an implementable manner, the program grouping rule may include the name of the application, and this grouping rule provides the possibility for fine-grained memory management, and the user can set different name grouping rules according to their own needs. Therefore, grouping multiple applications running on an electronic device based on the program grouping rule may include: grouping multiple applications running on an electronic device based on the name of the application. As an example, grouping multiple applications running on an electronic device based on the name of the application may include: grouping multiple applications running on an electronic device based on the package name of the application; or, grouping multiple applications running on an electronic device based on the process name of the process included in the application.

[0045] As an implementable manner, the program grouping rule may include an identification code of an application, wherein the identification code may be used to uniquely identify the application. This grouping rule provides the possibility for fine-grained memory management, and users can set different identification code grouping rules according to their needs. Therefore, grouping multiple applications running on an electronic device based on the program grouping rule may include: grouping multiple applications running on an electronic device based on the identification code of the application. As an example, grouping multiple applications running on an electronic device based on the identification code of the application may include: grouping multiple applications running on an electronic device based on the UID of the application.

[0046] As an implementable method, the program grouping rule may include the version number of the application program. It is understandable that different versions of the application program may have different memory usage characteristics. Therefore, the method of grouping multiple applications running on the electronic device based on the version number of the application program can make it possible to distinguish and manage different versions of the application program, which can improve the memory management effect. Therefore, grouping multiple applications running on the electronic device based on the program grouping rule may include: grouping multiple applications running on the electronic device based on the version number of the application program.

[0047] As an implementable manner, the program grouping rule may include a wildcard of the application program, and this grouping rule provides the possibility for complex grouping rules, such as including all applications starting with a certain prefix into a unified group for unified management. Therefore, grouping multiple applications running on the electronic device based on the program grouping rule may include: grouping multiple applications running on the electronic device based on the wildcard of the application program.

[0048] As an implementable manner, the program grouping rule may include a combination of at least two of the application name, the application identification code, the application version number, and the application wildcard, which will not be described in detail here.

[0049] In some embodiments, grouping multiple applications running on an electronic device may include grouping multiple applications in an include or exclude manner. For example, when grouping multiple applications running on an electronic device by application name, if it is an include operation, then applications containing a certain specific name will be included in the same group; if it is an exclude operation, then applications not containing a certain specific name will be included in the same group.

[0050] Step S140: performing memory management on each program group based on the memory swap strategy.

[0051] In this embodiment, when multiple program groups are obtained, content management can be performed on each of the multiple program groups based on the memory exchange strategy, so that the configuration file is used to manage the memory grouping and memory exchange strategy, which can make the memory management more flexible and refined. It can be understood that when multiple applications running on an electronic device are divided into multiple program groups and memory management is performed on each program group based on the memory exchange strategy, fine division management of the application can be achieved, avoiding improper replacement of important applications and causing improper impact on the operation of the application.

[0052] In some implementations, the number of the memory swap policies may be one or more. If the number of memory management policies is one, then, when multiple program groups are obtained, the multiple program groups may be separately memory managed based on the one memory management policy; if the number of memory management policies is multiple, then, when multiple program groups are obtained, the multiple program groups may be separately memory managed based on the multiple memory management policies, wherein the multiple memory management policies may be the same or different, which is not limited here.

[0053] As a detailed implementation, this embodiment can also group multiple processes in an application and perform memory management on the grouped processes. In some implementations, when the operating system of the electronic device is started, a preset configuration file is read from the operating system, the preset configuration file is parsed, a process grouping rule and a memory swap strategy are obtained, and multiple processes running on the electronic device are grouped based on the process grouping rule to obtain multiple process groups, wherein each of the multiple process groups includes at least one process, and memory management is performed on each process group based on the memory swap strategy.

[0054] A memory management method provided in an embodiment of the present application, when the operating system of an electronic device is started, reads a preset configuration file from the operating system, parses the preset configuration file, obtains program grouping rules and memory exchange strategies, groups multiple application programs running on the electronic device based on the program grouping rules, obtains multiple program groups, wherein each of the multiple program groups includes at least one application program, and performs memory management on each program group based on the memory exchange strategy, thereby grouping the running application programs by setting the program grouping rules through the configuration file, and performing memory management on the grouped application programs by using the memory exchange strategy set in the configuration file, which can make memory management more flexible and sophisticated.

[0055] See also Figure 2 , Figure 2 The flowchart of the memory management method provided by an embodiment of the present application is shown in FIG. Figure 2 The process shown is described in detail, and the memory management method may specifically include the following steps:

[0056] Step S210: when the operating system of the electronic device is started, start a target program, wherein the target program is used to group application programs and perform memory management on the grouped application programs.

[0057] In this embodiment, the electronic device may pre-create a target program, wherein the target program may be a memory grouping parsing service program, and the target program is used to group applications and perform memory management on the grouped applications. Optionally, the target program is in a closed state (not started state) by default.

[0058] In some implementations, when the operating system of the electronic device is started, a target program may be started simultaneously to group the application programs and perform memory management on the grouped application programs through the target program.

[0059] Step S220: reading the preset configuration file from the operating system through the target program.

[0060] In some embodiments, when the target program is started, the preset configuration file can be read from the operating system through the target program. Subsequently, the preset configuration file is parsed by the target program to obtain program grouping rules and memory swap strategies, and multiple applications running on the electronic device are grouped by the target program based on the program grouping rules. Finally, the memory of each program group is managed by the target program based on the memory swap strategy.

[0061] Step S230: parsing the preset configuration file through the target program to obtain program grouping rules and memory swap strategies.

[0062] Step S240: grouping the multiple application programs running on the electronic device based on the program grouping rule through the target program to obtain multiple program groups, wherein each program group in the multiple program groups includes at least one application program.

[0063] Step S250: performing memory management on each program group through the target program based on the memory swap strategy.

[0064] For the detailed description of step S230 to step S250 , please refer to step S120 to step S140 , which will not be repeated here.

[0065] The memory management method provided by an embodiment of the present application starts a target program when the operating system of the electronic device is started, wherein the target program is used to group the application programs and perform memory management on the grouped application programs, reads a preset configuration file from the operating system through the target program, parses the preset configuration file through the target program, obtains program grouping rules and memory exchange strategies, and groups multiple application programs running on the electronic device based on the program grouping rules through the target program to obtain multiple program groups, wherein each of the multiple program groups includes at least one application program, and manages each program group based on the memory exchange strategy through the target program. Compared to Figure 1 The memory management method shown in the figure, this embodiment also starts the target program to group the application programs and perform memory management on the grouped application programs, thereby improving the grouping and internal management effects.

[0066] See also Figure 3 , Figure 3 The flowchart of the memory management method provided by an embodiment of the present application is shown. The method is applied to an electronic device. In this embodiment, the number of memory exchange strategies is multiple, and the multiple memory exchange strategies are different. Figure 3 The process shown is described in detail, and the memory management method may specifically include the following steps:

[0067] Step S310: when the operating system of the electronic device is started, read a preset configuration file from the operating system.

[0068] Step S320: Parse the preset configuration file to obtain program grouping rules and memory swap strategies.

[0069] Step S330: Grouping the multiple application programs running on the electronic device based on the program grouping rule to obtain multiple program groups, wherein each program group in the multiple program groups includes at least one application program.

[0070] For the detailed description of step S310 to step S330 , please refer to step S110 to step S130 , which will not be repeated here.

[0071] Step S340: Determine a memory swap strategy that is compatible with each program group from the multiple memory swap strategies.

[0072] Optionally, there are multiple memory swap policies, and the multiple memory swap policies are different. For example, the triggering conditions of the multiple memory swap policies are different, the execution times of the multiple memory swap policies are different, the memory swap amounts of the multiple memory swap policies are different, etc., which are not limited here.

[0073] In some implementations, when multiple memory swap strategies and multiple program groups are obtained, a memory swap strategy adapted to each of the multiple program groups can be determined from the multiple memory swap strategies. Based on this, different memory swap strategies can be set for each program group, providing a more flexible memory management mechanism, and customized management can be performed according to the characteristics of each program group.

[0074] As an example, assume that the multiple memory exchange policies include a first memory exchange policy, a second memory exchange policy, and a third memory exchange policy, wherein the first memory exchange policy, the second memory exchange policy, and the third memory exchange policy are different, and the multiple program groups include a first program group, a second program group, and a third program group. Then, from the first memory exchange policy, the second memory exchange policy, and the third memory exchange policy, a first memory exchange policy adapted to the first program group, a second memory exchange policy adapted to the second program group, and a third memory exchange policy adapted to the third program group can be determined.

[0075] In some embodiments, when multiple memory swap strategies and multiple program groups are obtained, the corresponding characteristics of the multiple program groups (such as video playback characteristics, instant messaging characteristics, information query characteristics, etc.) can be obtained, and based on the corresponding characteristics of the multiple program groups, a memory swap strategy adapted to each program group can be determined from the multiple memory swap strategies.

[0076] In some embodiments, when multiple memory swap strategies and multiple program groups are obtained, the number of applications included in each of the multiple program groups can be obtained, and based on the number of applications included in each of the multiple program groups, a memory swap strategy adapted to each program group can be determined from the multiple memory swap strategies.

[0077] In some embodiments, when multiple memory swap strategies and multiple program groups are obtained, the operating frequencies of the applications included in each of the multiple program groups can be obtained, and based on the operating frequencies of the applications included in each of the multiple program groups, a memory swap strategy adapted to each program group can be determined from the multiple memory swap strategies.

[0078] In some embodiments, when multiple memory swap strategies and multiple program groups are obtained, the running times of the applications included in each of the multiple program groups can be obtained, and based on the running times of the applications included in each of the multiple program groups, a memory swap strategy adapted to each program group can be determined from the multiple memory swap strategies.

[0079] Step S350: performing memory management on each program group based on a memory swap strategy adapted to each program group.

[0080] In this embodiment, after determining the memory swap strategy adapted to each program group, memory management can be performed on each program group based on the memory swap strategy adapted to each program group, thereby achieving customized memory management for different program groups and improving the memory management effects of different program groups.

[0081] The memory management method provided by an embodiment of the present application reads a preset configuration file from the operating system when the operating system of the electronic device is started, parses the preset configuration file, obtains program grouping rules and memory exchange strategies, groups multiple application programs running on the electronic device based on the program grouping rules, obtains multiple program groups, wherein each of the multiple program groups includes at least one application program, determines a memory exchange strategy adapted to each program group from the memory exchange strategy, and performs memory management on each program group based on the memory exchange strategy adapted to each program group. Compared to Figure 1 The memory management method shown in the figure, this embodiment can also set different memory exchange strategies for memory management according to the characteristics of each program group, thereby providing a more flexible memory management mechanism and improving the memory management effect.

[0082] See also Figure 4 , Figure 4The flowchart of the memory management method provided by an embodiment of the present application is shown. The method is applied to an electronic device. For each program group in a plurality of program groups, the following will be directed to Figure 4 The process shown is described in detail, and the memory management method may specifically include the following steps:

[0083] Step S410: when the operating system of the electronic device is started, read a preset configuration file from the operating system.

[0084] Step S420: Parse the preset configuration file to obtain program grouping rules and memory swap strategies.

[0085] Step S430: Grouping the multiple application programs running on the electronic device based on the program grouping rule to obtain multiple program groups, wherein each program group in the multiple program groups includes at least one application program.

[0086] For the detailed description of step S410 to step S430 , please refer to step S110 to step S130 , which will not be repeated here.

[0087] Step S440: If the running state of at least one application program included in the program group changes, triggering execution of the memory swap policy on the program group.

[0088] In this embodiment, when multiple applications running on an electronic device are divided into multiple program groups, the running state of at least one application included in each program group can be detected for each of the multiple program groups to determine whether the running state of at least one application included in each program group has changed. If it is determined that the running state of one or more applications in at least one application included in the program group has changed, it can be determined to trigger the execution of a memory swap strategy for the program group; if it is determined that the running state of at least one application included in the program group has not changed, it can be determined not to trigger the execution of a memory swap strategy for the program group.

[0089] In some implementations, triggering execution of a memory swap policy for the program group may include: swapping out data pages corresponding to the program group from the memory to the Swap Space, or swapping data pages corresponding to the program group from the Swap Space into the memory.

[0090] In some implementations, the memory swap policy can use the policy execution method in Linux, such as updating LRU, identifying the working set, removing active pages, removing inactive pages, specifying the swap destination, etc. This provides a rich memory management policy that can meet various memory usage scenarios.

[0091] As an implementable manner, the change in the running state of at least one application included in the program group may include: at least one application included in the program group switches from running in the foreground of the electronic device to running in the background of the electronic device. It is understandable that because the memory usage characteristics of the application running in the foreground of the electronic device and the application running in the background of the electronic device are often different, different management strategies can be applied to the application running in the foreground of the electronic device and the application running in the background of the electronic device, that is, triggering the execution of the memory exchange strategy. As an implementable manner, when multiple applications running on the electronic device are divided into multiple program groups, for each of the multiple program groups, it is possible to detect whether at least one application included in it switches from running in the foreground of the electronic device to running in the background of the electronic device. For example, a listening program can be registered to detect whether at least one application switches from running in the foreground of the electronic device to running in the background of the electronic device.

[0092] As another practicable manner, the change in the running state of at least one application included in the program group may include: at least one application included in the program group switches from running in the foreground of the electronic device to stopping running. It is understandable that, because the memory usage characteristics of the application running in the foreground of the electronic device and the application stopped running in the electronic device are often different, different management strategies can be applied to the application running in the foreground of the electronic device and the application not running in the electronic device, that is, triggering the execution of the memory exchange strategy. As an practicable manner, when multiple applications running on the electronic device are divided into multiple program groups, for each of the multiple program groups, it is possible to detect whether at least one application included therein switches from running in the foreground of the electronic device to stopping running in the electronic device. For example, a listening program can be registered to detect whether at least one application switches from running in the foreground of the electronic device to stopping running in the electronic device.

[0093] As another practicable manner, the change in the running state of at least one application included in the program group may include: at least one application included in the program group switches from running in the background of the electronic device to running in the foreground of the electronic device. It is understandable that because the memory usage characteristics of the application running in the background of the electronic device and the application running in the foreground of the electronic device are often different, different management strategies can be applied to the application running in the background of the electronic device and the application running in the foreground of the electronic device, that is, triggering the execution of the memory exchange strategy. As an practicable manner, when multiple applications running on the electronic device are divided into multiple program groups, for each of the multiple program groups, it is possible to detect whether at least one application included in it switches from running in the background of the electronic device to running in the foreground of the electronic device. For example, a monitoring program can be registered to detect whether at least one application switches from running in the background of the electronic device to running in the foreground of the electronic device.

[0094] Step S450: If the running state of at least one application program included in the program group changes, triggering execution of the memory swap strategy for the program group after waiting for a preset time.

[0095] In this embodiment, when multiple applications running on an electronic device are divided into multiple program groups, for each of the multiple program groups, the running state of at least one application included in each program group can be detected to determine whether the running state of at least one application included in each program group has changed. If it is determined that the running state of one or more applications in at least one application included in the program group has changed, it can be determined to trigger the execution of a memory swap strategy for the program group after waiting for a preset time; if it is determined that the running state of at least one application included in the program group has not changed, it can be determined not to trigger the execution of a memory swap strategy for the program group. It can be understood that waiting for a preset time to trigger the execution of a memory swap strategy for the program group can prevent unnecessary memory management overhead generated when applications are frequently switched.

[0096] In some embodiments, triggering execution of a memory swap strategy for the program group after waiting for a preset period of time may include: swapping out data pages corresponding to the program group from the memory to the Swap Space after waiting for a preset period of time, or swapping data pages corresponding to the program group from the Swap Space into the memory after waiting for a preset period of time.

[0097] Among them, either step S440 or step S450 can be selected to be executed.

[0098] Step S460: Determine the number of error pages corresponding to at least one application program included in the program group.

[0099] After executing the memory swap strategy, the page refault value corresponding to the application can be monitored. When it exceeds the set threshold, the current memory swap strategy can be stopped, thereby preventing performance degradation caused by excessive memory swapping.

[0100] In this embodiment, after executing the memory swap strategy, the number of error pages corresponding to at least one application included in the program group can be determined. As a way, the electronic device can register a counter, and after executing the memory swap strategy, the number of error pages corresponding to at least one application included in the program group can be determined by the counter.

[0101] As an example, assuming that the program group includes a first application, a second application, and a third application, and the first application corresponds to 3 error pages, the second application corresponds to 2 error pages, and the third application corresponds to 0 error pages. Then, it can be determined that the number of error pages corresponding to at least one application included in the program group is 5.

[0102] In some embodiments, the electronic device may be pre-set with a duration as a preset duration. After executing the memory swap strategy, the number of error pages corresponding to at least one application included in the program group within the preset duration may be determined. Optionally, the preset duration may be fixed after being set, or the preset duration may be dynamically changed after being set, which is not limited here.

[0103] Step S470: If the number of error pages exceeds the number threshold, stop executing the memory swap strategy for the program group.

[0104] In some embodiments, the electronic device may pre-set and store a quantity threshold value, which is used as a basis for judging the number of error pages. Therefore, in this embodiment, when the number of error pages is obtained, the number of error pages can be compared with the quantity threshold value to determine whether the number of error pages exceeds the data threshold value. If it is determined that the number of error pages exceeds the quantity threshold value, the memory swap strategy can be stopped for the program group to prevent performance degradation caused by excessive memory swapping. If it is determined that the number of error pages does not exceed the quantity threshold value, the memory swap strategy can continue to be executed on the program group to improve the memory management effect.

[0105] A memory management method provided in an embodiment of the present application reads a preset configuration file from the operating system when the operating system of the electronic device is started, parses the preset configuration file, obtains program grouping rules and memory exchange strategies, groups multiple applications running on the electronic device based on the program grouping rules, and obtains multiple program groups, wherein each of the multiple program groups includes at least one application, and if the running state of at least one application included in the program group changes, the memory exchange strategy is triggered to be executed on the program group, or if the running state of at least one application included in the program group changes, the memory exchange strategy is executed on the program group after waiting for a preset period of time, and the number of error pages corresponding to at least one application included in the program group is determined. If the number of error pages exceeds a quantity threshold, the memory exchange strategy is stopped to be executed on the program group. Compared to Figure 1 The memory management method shown in this embodiment also triggers the execution of a memory swap strategy when the state of an application in a program group changes to adapt to the state change of the application; or, triggers the execution of a memory swap strategy after waiting for a preset time to prevent unnecessary memory management overhead generated when the application is frequently switched. In addition, after executing the memory swap strategy, if the number of error pages corresponding to the application included in the program group exceeds a quantity threshold, the execution of the memory swap strategy is stopped to reduce the impact on the operation of the application.

[0106] See also Figure 5 , Figure 5 The flowchart of the memory management method provided by an embodiment of the present application is shown in FIG. Figure 5 The process shown is described in detail, and the memory management method may specifically include the following steps:

[0107] Step S510: when the operating system of the electronic device is started, read a preset configuration file from the operating system.

[0108] Step S520: Parse the preset configuration file to obtain program grouping rules and memory swap strategies.

[0109] Step S530: Grouping the multiple application programs running on the electronic device based on the program grouping rule to obtain multiple program groups, wherein each program group in the multiple program groups includes at least one application program.

[0110] For the detailed description of step S510 to step S530 , please refer to step S110 to step S130 , which will not be repeated here.

[0111] Step S540: Obtain the memory occupancy rate of the electronic device.

[0112] In this embodiment, the memory occupancy rate of the electronic device may be obtained.

[0113] In some implementations, the memory occupancy rate of the electronic device may be obtained in real time, at time intervals, at time points, or according to other rules, which are not limited here.

[0114] Optionally, if the memory occupancy rate of the electronic device is obtained at time intervals, the memory occupancy rate of the electronic device may be obtained at fixed time intervals, or the memory occupancy rate of the electronic device may be obtained at exponentially increasing time intervals.

[0115] In some implementations, the electronic device may obtain the memory capacity in advance, and then obtain the memory occupancy of the electronic device, and determine the memory occupancy rate of the electronic device based on the memory occupancy and the memory capacity.

[0116] Step S550: If the memory occupancy rate reaches an occupancy rate threshold, triggering execution of the memory swap strategy for at least one program group among the multiple program groups.

[0117] In some embodiments, the electronic device may pre-set and store an occupancy threshold value, and the occupancy threshold value is used as a basis for judging the memory occupancy of the electronic device. Therefore, in this embodiment, when the memory occupancy of the electronic device is obtained, the memory occupancy rate and the occupancy threshold value may be compared to determine whether the memory occupancy rate reaches the occupancy threshold value. Among them, if it is determined that the memory occupancy rate reaches the occupancy threshold value, it is determined that the memory occupancy of the electronic device is too high, and the data in the memory of the electronic device may be swapped out to the Swap Space to reduce the memory occupancy of the electronic device, that is, triggering the execution of a memory exchange strategy for at least one program group in the multiple program groups to dynamically adjust the memory exchange strategy. If it is determined that the memory occupancy rate does not reach the occupancy threshold value, it is determined that the memory occupancy of the electronic device is low, and the memory exchange strategy may not be executed for multiple program groups.

[0118] The memory management method provided by an embodiment of the present application reads a preset configuration file from the operating system when the operating system of the electronic device is started, parses the preset configuration file, obtains program grouping rules and memory swap strategies, groups multiple application programs running on the electronic device based on the program grouping rules, obtains multiple program groups, wherein each of the multiple program groups includes at least one application program, obtains the memory occupancy rate of the electronic device, and triggers the execution of the memory swap strategy for at least one of the multiple program groups if the memory occupancy rate reaches the occupancy rate threshold. Compared to Figure 1The memory management method shown in this embodiment also triggers the execution of a memory swap strategy when the memory occupancy rate of the electronic device reaches an occupancy rate threshold, thereby avoiding the impact of excessive memory occupancy rate on the operation of the electronic device and improving the operation effect of the electronic device.

[0119] See also Figure 6 , Figure 6 The flowchart of the memory management method provided by an embodiment of the present application is shown in FIG. Figure 6 The process shown is described in detail, and the memory management method may specifically include the following steps:

[0120] Step S610: when the operating system of the electronic device is started, read a preset configuration file from the operating system.

[0121] Step S620: Parse the preset configuration file to obtain program grouping rules and memory swap strategies.

[0122] Step S630: Grouping the multiple application programs running on the electronic device based on the program grouping rule to obtain multiple program groups, wherein each program group in the multiple program groups includes at least one application program.

[0123] For the detailed description of step S610 to step S630 , please refer to step S110 to step S130 , which will not be repeated here.

[0124] Step S640: If there is a newly-added running application on the electronic device, the newly-added running application is added to a first target program group based on the program grouping rule, wherein the first target program group is any one of the multiple program groups.

[0125] In this embodiment, newly created (newly running) applications can also be monitored to determine whether the newly created applications meet the grouping conditions. If so, the newly created applications can be included in the corresponding program group. As an implementable method, it is possible to detect whether there are newly running applications on the electronic device. Optionally, it is possible to detect whether there are newly added applications running in the foreground of the electronic device, and to detect whether there are newly added applications running in the background of the electronic device. If it is detected that there are newly added applications running in the foreground of the electronic device or there are newly added applications running in the background of the electronic device, it can be determined that there are newly running applications on the electronic device.

[0126] In some implementations, the electronic device may register a monitor, and the monitor may be used to detect whether there is a newly-running application on the electronic device.

[0127] If a newly-added running application is detected in the electronic device, the newly-added running application can be added to a first target program group based on the program grouping rule, wherein the first target program group is any one of the multiple program groups. That is, if a newly-added running application is detected in the electronic device, the newly-added running application can be added to a divided program group based on the program grouping rule.

[0128] As an implementable method, if it is detected that there is a newly running application on the electronic device, the characteristics of the newly running application can be determined, and the characteristics corresponding to each of the multiple program groups can be determined, and the characteristics of the newly running application can be compared with the characteristics corresponding to each of the multiple program groups to determine whether the characteristics corresponding to each of the multiple program groups include characteristics that match the characteristics of the newly running application. If so, the newly running application is added to the program group in the multiple program groups that matches its characteristics.

[0129] Step S650: If there is a newly-added application program in the electronic device, the newly-added application program is divided into a second target program group based on the program grouping rule, wherein the second target program group is different from the plurality of program groups.

[0130] If a newly-added running application is detected in the electronic device, the newly-added running application can be added to the second target program group based on the program grouping rule, wherein the second target program group is different from the plurality of program groups. That is, if a newly-added running application is detected in the electronic device, the newly-added running application can be separately classified into a new program group based on the program grouping rule.

[0131] As an implementable method, if it is detected that there is a newly running application on the electronic device, the characteristics of the newly running application can be determined, and the characteristics corresponding to each of the multiple program groups can be determined, and the characteristics of the newly running application can be compared with the characteristics corresponding to each of the multiple program groups to determine whether the characteristics corresponding to each of the multiple program groups include characteristics that match the characteristics of the newly running application. If not, the newly running application will be divided into a new program group (second target program group).

[0132] Among them, one of step S640 and step S650 is selected to be executed.

[0133] Step S660: Based on the memory swap strategy, memory management is performed on each program group.
