Detailed Description
In order to make the technical solutions better understood by those skilled in the art, 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.
Taking the Android operating system as an example, under a memory management mechanism of the Android operating system, when the memory occupancy of the system reaches an upper limit, the system randomly releases memory resources occupied by processes running in a background, so as to reduce the occupancy rate of the memory of the system and improve the performance of the system. However, the current Android operating system starts to release the memory resources occupied by the processes running in the background only in the memory recovery process when the available memory is lower than the set threshold, and cannot make adjustments in time to quickly meet the requirement of a large memory in a short time, which may cause a problem of blocking.
In view of the above problems, the inventors have found and proposed a memory recovery processing method, device, electronic device and storage medium provided in the embodiments of the present application through long-term research, and when a sudden increase in the number of times of memory recovery of the electronic device is detected, the process of operating the electronic device is cleared and the memory resource is released, so as to improve the system performance. The specific memory recycling method is described in detail in the following embodiments.
Referring to fig. 1, fig. 1 is a schematic flowchart illustrating a memory recycling method according to an embodiment of the present disclosure. The memory recovery processing method is used for cleaning the running process of the electronic equipment and releasing memory resources when the sudden increase of the memory recovery times of the electronic equipment is detected so as to improve the system performance. In an embodiment, the memory recycling method is applied to the memory recycling device 200 shown in fig. 7 and the electronic device 100 (fig. 8) equipped with the memory recycling device 200. The specific process of the present embodiment will be described below by taking an electronic device as an example, and it is understood that the electronic device applied in the present embodiment may be a smart phone, a tablet computer, a wearable electronic device, and the like, which is not limited herein. As will be described in detail with respect to the flow shown in fig. 1, the memory recycling method may specifically include the following steps:
step S110: and detecting the memory recovery times of the electronic equipment in a specified time period.
In some embodiments, the electronic device may be preset with a specific time period, wherein the specific time period may be set automatically by the electronic device or manually by a user, which is not limited herein. In addition, the specified time period may be set to 1 second, to 1 minute, to 1 hour, or the like, and is not limited herein. In this embodiment, the specified time period is used as a time determination basis for detecting the memory recovery times of the electronic device, that is, the specified time period may be used as a detection period to detect the memory recovery times of the electronic device. For example, when the specified time period is 1 second, the memory recovery times of the electronic device in the time period of 1 second may be detected; when the specified time period is 1 minute, the memory recovery times of the electronic device in the time period of 1 minute can be detected.
Of course, in some embodiments, the specified time period may be a recurring time period, wherein a recurring time period may include a continuous recurring time period and an intermittent recurring time period. For example, in this embodiment, the number of times of memory recovery of the electronic device may be circularly detected every 1 second as a time period, for example, the number of times of memory recovery of the electronic device may be continuously circularly detected every 1 second as a time period, or the number of times of memory recovery of the electronic device may be circularly detected every 1 second as a time period interval, which is not limited herein.
As a mode, the electronic device may perform recording or marking once every time the electronic device performs memory recovery, and therefore, in this embodiment, the number of times of memory recovery of the electronic device in a specified time period may be detected by querying the recording or marking. As another mode, the electronic device counts the memory recovery times at the starting time point of each time period, and completes counting the memory recovery times at the ending time point of each time period, so that the memory recovery times of the electronic device in the specified time period can be obtained.
Step S120: and judging whether the memory recovery times exceed a time threshold value.
In some embodiments, the electronic device may be provided with a number threshold, and the set number threshold is used as a criterion for determining the memory recycling number of the electronic device. Therefore, in this embodiment, after the number of times of memory recovery of the electronic device in the specified time period is detected, the number of times of memory recovery may be compared with the number threshold to determine whether the number of times of memory recovery exceeds the number threshold. For example, assume the number threshold is: the maximum memory recovery frequency of the 1 second time period is 1000 times, the memory recovery frequency of the electronic device in the 1 second time period can be detected, the detected memory recovery frequency is compared with 1000 times to judge whether the memory recovery frequency exceeds 1000 times, and if the memory recovery frequency exceeds 1000 times, the memory recovery frequency can be determined to exceed a frequency threshold.
The preset number threshold can be stored in the local of the electronic device after being completed, and the preset number threshold is used as a judgment basis for the memory recovery number. The initial number threshold may also be preset and stored locally in the electronic device, the initial number threshold is updated during the use of the electronic device, and the updated initial number threshold is used as a criterion for determining the memory recovery number, and the like, which is not limited herein.
In this embodiment, the number of times threshold set by the electronic device is at least one, that is, the number of times threshold is one or more. When the number of the times threshold is one, the memory recovery times can be compared with the times threshold to judge whether the memory recovery times exceeds the times threshold; when the number of times threshold is multiple, the number of times of memory recovery may be compared with the multiple number of times threshold, respectively, to determine whether the number of times of memory recovery exceeds any number of times threshold, and determine a target number of times threshold that the number of times of memory recovery exceeds from the multiple number of times threshold.
Step S130: and when the memory recovery times exceed the time threshold, cleaning the process operated by the electronic equipment and releasing the memory resources corresponding to the cleaned process.
In some embodiments, when the determination result indicates that the memory recovery frequency of the electronic device in the specified time period exceeds the frequency threshold, the increase of the memory recovery frequency is too fast, that is, the memory requirement is large, so that the process running on the electronic device can be cleaned and the memory resource corresponding to the cleaned process can be released, so as to release the memory resource in advance to meet the memory requirement, improve the system performance, and avoid the problem of blocking. As a manner, the electronic device may trigger a Low Memory Killer (LMK) to clean the running process and release a memory resource corresponding to the cleaned process, for example, kill a process running in a background of the electronic device through the LMK, release a memory resource corresponding to a process running in the background, and the like, which is not limited herein.
According to the memory recovery processing method provided by one embodiment of the application, the memory recovery times of the electronic device in a specified time period are detected, whether the memory recovery times exceed a time threshold is judged, when the memory recovery times exceed the time threshold, a process operated by the electronic device is cleaned, and memory resources corresponding to the cleaned process are released, so that when the memory recovery times of the electronic device are suddenly increased, the process operated by the electronic device is cleaned, the memory resources are released, and the system performance is improved.
Referring to fig. 2, fig. 2 is a schematic flow chart illustrating a memory recycling method according to another embodiment of the present application. The method is applied to an electronic device, and will be described in detail with reference to a flow shown in fig. 2, where in this embodiment, the number threshold includes a first number threshold and a second number threshold, and the first number threshold is smaller than the second number threshold, and the memory recycling method may specifically include the following steps:
step S210: when the electronic equipment runs a target process in a foreground, acquiring the residual memory resources of the electronic equipment and determining the memory resources required by the target process.
In some embodiments, the electronic device may detect a process running in the foreground to determine whether the process running in the foreground of the electronic device is a target process. For example, the Process Running in the foreground of the electronic device may be detected by Running Task, Running Process, Activity Lifecycle Callbacks, Usage states Manager, Android-owned barrier-free function of the electronic device, or Process information stored in a directory by a Linux system kernel. The Running process in the foreground of the electronic equipment is detected through the Running Task of the electronic equipment as an example, when one process runs in the foreground, the process can be located at the stack top of the Running Task, so that the Task process at the stack top of the Running Task can be taken out, the packet name of the process can be checked, and the Running process in the foreground of the electronic equipment can be identified through the packet name. Of course, in this embodiment, the process running in the foreground of the electronic device may also be detected in other more manners, which is not described herein again.
In this embodiment, after detecting a process running in the foreground of the electronic device, it may be determined whether the process is a target process. As a manner, the type of a process running in the foreground of the electronic device may be obtained, and whether the type satisfies a preset type or not may be determined. The preset type may include a video playing type, a video processing type, and other types with a large demand on the memory resource, and correspondingly, the target process may include a video playing process, a video processing process, and other types, which are not limited herein.
In some embodiments, when it is detected that the electronic device runs the target process in the foreground, the remaining memory resources of the electronic device may be obtained and the memory resources required by the target process may be determined. For example, when it is detected that the electronic device runs a video playing process in the foreground, the remaining memory resources of the electronic device may be obtained and the memory resources required by the video playing process may be determined.
For example, when an operating system of the electronic device is an Android system, the current available memory amount of the memory of the electronic device, that is, the remaining memory resource of the electronic device, may be obtained by an activitymanager.
The electronic device can determine the memory resources required by the target process by checking historical data or in an estimated mode. Taking an example that the electronic device determines the memory resource required by the target process by checking the historical data, the electronic device may set a preset history period, acquire the memory resource occupied by the electronic device when the target process is operated at the foreground each time in the preset history period, calculate the average memory resource occupied by the electronic device when the target process is operated at the foreground each time based on the memory resource occupied by the electronic device when the target process is operated at the foreground each time in the preset history period, and determine the average memory resource as the memory resource required by the target process. The preset history period may include approximately three days, approximately one week, approximately one month, and the like, and is not limited herein, and taking the preset history period as approximately three days as an example, the memory resource occupied by the electronic device running the target process in the foreground every time in the history period of approximately three days may be obtained, the average value of the memory resource occupied by the target process is calculated based on the memory resource occupied every time, and the average value is determined as the memory resource required by the target process.
Step S220: and when the residual memory resources are smaller than the memory resources required by the target process, detecting the memory recovery times of the electronic equipment in a specified time period.
In some embodiments, when the remaining memory resources of the electronic device and the memory resources required by the target process are obtained, the remaining memory resources and the memory resources required by the target process may be compared to determine whether the remaining memory resources are smaller than the memory resources required by the target process. When the judgment result represents that the residual memory resources are not less than the memory resources required by the target process, the residual memory resources of the electronic equipment can be continuously detected; and when the judgment result represents that the residual memory resources are smaller than the memory resources required by the target, the memory recovery times of the equipment with you in the specified time period can be detected.
Step S230: and judging whether the memory recovery times exceed a time threshold value.
In this embodiment, the number threshold includes a first number threshold and a second number threshold, and the first number threshold is smaller than the second number threshold. Therefore, as a manner, after the memory recovery times of the electronic device in the specified time period are obtained, the memory recovery times may be compared with the first time threshold and the second time threshold, respectively, to determine whether the memory recovery times do not exceed the first time threshold, whether the memory recovery times exceed the first time threshold and do not exceed the second time threshold, and whether the memory recovery times exceed the second time threshold.
Step S240: and when the memory recovery times exceed the first time threshold and do not exceed the second time threshold, determining a first preset number of processes corresponding to the first time threshold.
Step S250: and clearing the processes of the first preset number and releasing the memory resources corresponding to the processes of the first preset number.
When the judgment result indicates that the memory recovery times exceed the first time threshold and do not exceed the second time threshold, a first preset number of processes corresponding to the first time threshold can be determined, and then the first preset number of processes can be cleaned and the memory resources corresponding to the first preset number of processes can be released. In some embodiments, the electronic device may preset different numbers of processes corresponding to different times thresholds, for example, the first time threshold may be set to correspond to a first preset number of processes, and the second time threshold corresponds to a second preset number of processes, so that when the determination result indicates that the memory recovery time exceeds the first time threshold and does not exceed the second time threshold, the first preset number of processes corresponding to the first time threshold may be determined, and the first preset number of processes may be cleared to release the memory resource corresponding to the first preset number of processes, thereby improving system performance.
For example, the electronic device may preset X processes corresponding to the first time threshold, Y processes corresponding to the second time threshold, and the like, and then, when the determination result indicates that the number of times of memory recovery exceeds the first time threshold and does not exceed the second time threshold, the X processes corresponding to the first time threshold may be cleared and the memory resources corresponding to the X processes may be released.
Step S260: and when the memory recovery times exceed the second time threshold, determining a second preset number of processes corresponding to the second time threshold, wherein the second preset number is greater than the first preset number.
Step S270: and clearing the processes of the second preset number and releasing the memory resources corresponding to the processes of the second preset number.
When the judgment result indicates that the memory recovery times exceed the second time threshold, a second preset number of processes corresponding to the second time threshold can be determined, and the second preset number of processes can be cleaned and the memory resources corresponding to the second preset number of processes can be released. It should be noted that, in this embodiment, the second preset number is greater than the first preset number, that is, the greater the number threshold value that the number of times of memory recovery of the electronic device in the specified time period exceeds is, the greater the number of processes that are correspondingly determined and cleaned is, so that memory recovery can be accelerated, and system performance is improved. The electronic device selects the processes to be cleaned according to a certain sequence when determining the processes to be cleaned, for example, first selecting the processes to be cleaned of 100M, then cleaning the processes of 90M, and finally cleaning the processes of 80M, so that the processes of the second preset number determined by the electronic device include the processes of the first preset number, and therefore the memory resources occupied by the processes of the second preset number are larger than the memory resources occupied by the processes of the first preset number, so that the processes of different numbers to be cleaned can be determined according to different memory recycling times, and the process cleaning and the memory resource release are more reasonable.
For example, the electronic device may preset X processes corresponding to the first time threshold, and Y processes corresponding to the second time threshold, where X is less than Y, and then, when the determination result indicates that the number of times of memory recovery exceeds the second time threshold, the Y processes corresponding to the second time threshold may be cleared and the memory resources corresponding to the Y processes may be released. Of course, in this embodiment, the electronic device may further be provided with a number threshold more than the first number threshold and the second number threshold, and the more number thresholds correspond to different numbers of processes, so that the number of times of memory recovery may be compared with the more number thresholds, and a more reasonable number of processes may be determined to be cleaned, thereby accelerating memory recovery.
In another embodiment of the memory recycling method, when the electronic device runs the target process in the foreground, the remaining memory resources of the electronic device are obtained and the memory resources required by the target process are determined, when the remaining memory resources are smaller than the memory resources required by the target process, the memory recycling frequency of the electronic device in a specified time period is detected, whether the memory recycling frequency exceeds a frequency threshold is determined, when the memory recycling frequency exceeds a first frequency threshold and does not exceed a second frequency threshold, a first preset number of processes corresponding to the first frequency threshold are determined, the first preset number of processes are cleared and the memory resources corresponding to the first preset number of processes are released, when the memory recycling frequency exceeds the second frequency threshold, a second preset number of processes corresponding to the second frequency threshold are determined, wherein the second preset number is greater than the first preset number, and clearing the processes with the second preset number and releasing the memory resources corresponding to the processes with the second preset number. Compared with the memory recovery processing method shown in fig. 1, in this embodiment, the number of times of memory recovery detection is further determined according to the relationship between the memory resource required by the target process running in the foreground of the electronic device and the remaining memory resource of the electronic device, so as to reduce the power consumption of the electronic device.
Referring to fig. 3, fig. 3 is a schematic flow chart illustrating a memory recycling method according to still another embodiment of the present application. The method is applied to an electronic device, and will be described in detail with reference to a flow shown in fig. 3, where in this embodiment, the number threshold includes a third number threshold and a fourth number threshold, and the third number threshold is smaller than the fourth number threshold, and the memory recycling method may specifically include the following steps:
step S310: when the electronic equipment runs a target process in a foreground, acquiring the residual memory resources of the electronic equipment and determining the memory resources required by the target process.
Step S320: and when the residual memory resources are smaller than the memory resources required by the target process, detecting the memory recovery times of the electronic equipment in a specified time period.
For the detailed description of steps S310 to S320, please refer to steps S210 to S220, which are not described herein again.
Step S330: and judging whether the memory recovery times exceed a time threshold.
In this embodiment, the number threshold includes a third number threshold and a fourth number threshold, and the third number threshold is smaller than the fourth number threshold. Therefore, as one way, after the memory recovery times of the electronic device in the specified time period are obtained, the memory recovery times may be compared with the third time threshold and the fourth time threshold, respectively, to determine whether the memory recovery times do not exceed the third time threshold, whether the memory recovery times exceed the third time threshold and do not exceed the fourth time threshold, and whether the memory recovery times exceed the fourth time threshold.
Step S340: and when the memory recovery times exceed the third time threshold and do not exceed the fourth time threshold, determining a process corresponding to the third time threshold.
Step S350: and cleaning the process corresponding to the third time threshold value and releasing the memory resource corresponding to the process corresponding to the third time threshold value.
When the judgment result indicates that the memory recovery times exceed the third time threshold and do not exceed the fourth time threshold, the process corresponding to the third time threshold can be determined, and the process corresponding to the third time threshold can be cleaned and the memory resource corresponding to the process corresponding to the third time threshold can be released. In some embodiments, the electronic device may preset processes with different memory occupancy amounts corresponding to different times thresholds, for example, a process with a third time threshold corresponding to the first memory occupancy amount and a process with a fourth time threshold corresponding to the second memory occupancy amount, so that when the determination result indicates that the memory recovery time exceeds the third time threshold and does not exceed the fourth time threshold, the process corresponding to the third time threshold may be determined, and the process corresponding to the third time threshold is cleaned to release the memory resource corresponding to the process corresponding to the third time threshold, thereby improving system performance.
For example, the electronic device may preset a process with a memory occupation amount of M corresponding to the third time threshold, a process with a memory occupation amount of N corresponding to the fourth time threshold, and the like, and then, when the judgment result indicates that the memory recovery times exceed the third time threshold and do not exceed the fourth time threshold, the process with the memory occupation amount of M may be queried, and the process with the memory occupation amount of M may be cleaned and the memory resource corresponding to the process with the memory occupation amount of M may be released.
Step S360: and when the memory recovery times exceed the fourth time threshold, determining a process corresponding to the fourth time threshold, wherein the memory resource occupied by the process corresponding to the fourth time threshold is greater than the memory resource occupied by the process corresponding to the third time threshold.
Step S370: and cleaning the process corresponding to the fourth time threshold value and releasing the memory resource corresponding to the process corresponding to the fourth time threshold value.
When the judgment result indicates that the memory recovery times exceed the fourth time threshold, the process corresponding to the fourth time threshold can be determined, and the process corresponding to the fourth time threshold can be cleaned and the memory resource corresponding to the process corresponding to the fourth time threshold can be released. It should be noted that, in this embodiment, the memory resource occupied by the process corresponding to the fourth time threshold is greater than the memory resource occupied by the process corresponding to the third time threshold, that is, the larger the number threshold is exceeded by the number of times of memory recovery of the electronic device in the specified time period, the more the memory resource occupied by the process that is correspondingly determined and cleaned is, so that memory recovery can be accelerated, and system performance is improved.
For example, the electronic device may preset a process with a memory occupation amount of M corresponding to a third time threshold, and a process with a memory occupation amount of N corresponding to a fourth time threshold, where M is less than N, for example, M is 90M, and N is 100M, and then when the determination result indicates that the memory recovery time exceeds the fourth time threshold, the process with the memory occupation amount of N may be queried, and the process with the memory occupation amount of N may be cleaned and the memory resource corresponding to the process with the memory occupation amount of N may be released. Of course, in this embodiment, the electronic device may further be provided with a number threshold more than the third number threshold and the fourth number threshold, and the more number thresholds correspond to processes with different memory occupancy amounts, so that the memory recovery number can be compared with the more number thresholds, and the processes with more reasonable memory occupancy amounts are determined to be cleaned, thereby accelerating memory recovery.
A memory recovery processing method provided in another embodiment of the present application, when an electronic device runs a target process in a foreground, obtaining remaining memory resources of the electronic device and determining memory resources required by the target process, when the remaining memory resources are less than the memory resources required by the target process, detecting a memory recovery frequency of the electronic device in a specified time period, determining whether the memory recovery frequency exceeds a frequency threshold, when the memory recovery frequency exceeds a third frequency threshold and does not exceed a fourth frequency threshold, determining a process corresponding to the third frequency threshold, cleaning the process corresponding to the third frequency threshold and releasing the memory resources corresponding to the process corresponding to the third frequency threshold, when the memory recovery frequency exceeds the fourth frequency threshold, determining a process corresponding to the fourth frequency threshold, where the memory resources occupied by the process corresponding to the fourth frequency threshold are greater than the memory resources occupied by the process corresponding to the third frequency threshold, and cleaning the process corresponding to the fourth number threshold value and releasing the memory resource corresponding to the process corresponding to the fourth number threshold value. Compared with the memory recovery processing method shown in fig. 1, in this embodiment, the number of times of memory recovery detection is further determined according to the relationship between the memory resource required by the target process running in the foreground of the electronic device and the remaining memory resource of the electronic device, so as to reduce the power consumption of the electronic device.
Referring to fig. 4, fig. 4 is a schematic flowchart illustrating a memory recycling method according to another embodiment of the present disclosure. The method is applied to the electronic device, and will be described in detail with reference to the flow shown in fig. 4, where the memory recycling method may specifically include the following steps:
step S410: when the electronic equipment runs a target process in a foreground, acquiring the residual memory resources of the electronic equipment and determining the memory resources required by the target process.
Step S420: and when the residual memory resources are smaller than the memory resources required by the target process, detecting the memory recovery times of the electronic equipment in a specified time period.
For the detailed description of steps S410 to S420, refer to steps S210 to S220, which are not described herein again.
Step S430: and judging whether the memory recovery times exceed a time threshold.
For detailed description of step S430, please refer to step S120, which is not described herein again.
Step S440: and when the memory recovery times exceed the time threshold, acquiring all processes running in the background of the electronic equipment.
In some embodiments, when the determination result indicates that the number of times of memory recovery of the electronic device in the specified time period exceeds the number threshold, all processes running in the background of the electronic device may be acquired.
Step S450: and determining the process with the operating frequency lower than the preset operating frequency from all the processes.
Further, the electronic device may be preset with a preset operating frequency, where the preset operating frequency is used as a basis for determining an operating frequency of each process in all processes running in the background of the electronic device. Therefore, in this embodiment, after all the processes running in the background of the electronic device are acquired, the running frequency of each process in all the processes may be detected respectively, and the running frequency of each process may be compared with the preset running frequency respectively, so as to determine a process, of which the running frequency is lower than the preset running frequency, from all the processes. In some embodiments, the detected operating frequency of each process may be an operating frequency of each detected process within a preset time period, for example, an operating frequency of each detected process on the last three days, an operating frequency of each detected process on the last week, and the like, which is not limited herein.
Referring to fig. 5, fig. 5 is a flowchart illustrating the step S450 of the memory reclamation processing method illustrated in fig. 4 according to the present application. As will be explained in detail with respect to the flow shown in fig. 5, the method may specifically include the following steps:
step S451: acquiring a current time point and determining a time period to which the current time point belongs.
As an embodiment, when the determination result indicates that the memory recovery frequency of the electronic device in the specified time period exceeds the frequency threshold, the electronic device may obtain a current time point, and determine a time period to which the current time point belongs, specifically, the electronic device may divide the time period in advance, for example, the electronic device may divide a day into 3 time periods, 12 time periods, 24 time periods, and the like, and, taking dividing the day into 3 time periods as an example, the electronic device may divide the day into 6.00 to 14.00 time periods, 14.00 to 22.00 time periods, and 22.00 to 6.00 time periods, then, if the current time point is 8.30, the time period to which the current time point belongs may be determined to be 6.00 to 14.00 time periods, and if the current time point is 15.30, the time period to which the current time point belongs may be determined to be 14.00 to 22.00 time periods.
Step S452: determining the running frequency of each process in all the processes in the time period.
After the time period to which the current time point belongs is determined, the operating frequency of each process in all the processes in the time period may be queried. For example, if it is determined that the time period to which the current time point belongs is 6.00 to 14.00, the operating frequency of each process in all the processes in the range from 6.00 to 14.00 may be queried. It can be understood that the usage habits of each user in different time periods of a day are different, for example, the user is used to watch news in the morning, drama in the afternoon, books in the evening, and the like, so that the processes that the electronic device may run in different time periods are different based on the usage habits of the user, and as a way, the running frequency of each process in all the processes in the time period can be determined, so as to improve the matching degree with the usage habits of the user, and improve the user experience.
Certainly, in this embodiment, the electronic device may further divide more time periods, for example, the time periods may be divided by taking 30 minutes and 10 minutes as the time periods, so as to improve the detection accuracy of the operating frequency of each process in the time period, which is not described herein again.
Step S453: and determining the process with the operating frequency lower than the preset operating frequency from all the processes based on the operating frequency of each process in the time period.
In some embodiments, after the operation frequency of each process in the time period is determined, a process with the operation frequency lower than a preset operation frequency can be determined from all the processes based on the operation frequency of each process in the time period, so that the problem that the process determined to be cleaned is a process that a user is accustomed to calling in the time period, and the power consumption of the electronic device is increased is avoided. For example, if the time period is 14.00 to 22.00, and the user is accustomed to watching dramas, reading books or reading news in the time period, the operation frequency of the drama-reading process in the 14.00 to 22.00 range is higher than the preset operation frequency, and the operation frequency of the book-reading process or the news-reading process in the 14.00 to 22.00 range is lower than the preset operation frequency, so that the book-reading process and the news-reading process can be determined as processes with the operation frequency lower than the preset operation frequency, so that the book-reading process and the news-reading process can be cleaned subsequently, and memory resources corresponding to the book-reading process and the news-reading process are released.
Step S460: and cleaning the process with the operating frequency lower than the preset operating frequency and releasing the memory resource corresponding to the process with the operating frequency lower than the preset operating frequency.
In another embodiment of the present application, a flow diagram of a memory recycling processing method is provided, where when an electronic device runs a target process in a foreground, remaining memory resources of the electronic device are obtained and memory resources required by the target process are determined, when the remaining memory resources are smaller than the memory resources required by the target process, a memory recycling frequency of the electronic device in a specified time period is detected, whether the memory recycling frequency exceeds a frequency threshold is determined, when the memory recycling frequency exceeds the frequency threshold, all processes running in the background of the electronic device are obtained, a process with a running frequency lower than a preset running frequency is determined from all the processes, a process with a running frequency lower than the preset running frequency is cleaned, and memory resources corresponding to the process with a running frequency lower than the preset running frequency are released. Compared with the memory recovery processing method shown in fig. 1, in this embodiment, the number of times of memory recovery detection is further determined according to a relationship between the memory resource required by the target process running in the foreground of the electronic device and the remaining memory resource of the electronic device, so as to reduce power consumption of the electronic device.

The method is applied to the electronic device, and will be described in detail with reference to the flow shown in fig. 6, where the memory recycling method may specifically include the following steps:
step S510: when the electronic equipment runs a target process in a foreground, acquiring the residual memory resources of the electronic equipment and determining the memory resources required by the target process.
Step S520: and when the residual memory resources are smaller than the memory resources required by the target process, detecting the memory recovery times of the electronic equipment in a specified time period.

Step S530: and judging whether the memory recovery times exceed a time threshold value.
For the detailed description of step S530, please refer to step S120, which is not described herein again.
Step S540: and when the memory recovery times exceed the time threshold, acquiring a to-be-cleaned process which is operated by the electronic equipment and meets a preset cleaning list.
In some embodiments, when the determination result indicates that the memory recovery frequency of the electronic device in the specified time period exceeds the frequency threshold, a waiting cleaning process that is run by the electronic device and meets a preset cleaning list may be obtained. Specifically, in this embodiment, the electronic device may create a preset cleaning list in advance, where the preset cleaning list is used to add a process that can be cleaned preferentially, and the process that can be cleaned preferentially is used as the process to be cleaned, so that when the memory recovery frequency exceeds the frequency threshold, the electronic device may preferentially acquire the process to be cleaned from the preset cleaning list, so as to reduce false cleaning of the process.
Step S550: and cleaning the progress to be cleaned and releasing the memory resource corresponding to the progress to be cleaned.
Furthermore, after the process to be cleaned is obtained, the process to be cleaned can be cleaned and the memory resource corresponding to the process to be cleaned is released, so that the process cleaning efficiency and accuracy are improved.
