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 adjust memory recovery parameters of the electronic device when detecting that the number of times of memory recovery of the electronic device suddenly increases, so as to accelerate the memory recovery speed and 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 adjusting the memory recovery parameters of the electronic equipment when the sudden increase of the memory recovery times of the electronic equipment is detected, so that the memory recovery speed is accelerated, and the system performance is improved. 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 cyclically detected with a time period of every 1 second, for example, the number of times of memory recovery of the electronic device may be cyclically detected continuously with a time period of every 1 second, or the number of times of memory recovery of the electronic device may be cyclically detected at intervals with a time period of every 1 second, 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, so as 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, adjusting memory recovery parameters of the electronic equipment to accelerate the memory recovery speed, wherein the memory recovery parameters represent the recovery ratio of the anonymous page and the file page.
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 memory recovery parameter (swappiess) of the electronic device may be adjusted to accelerate the memory recovery speed. In this embodiment, the memory recycle parameter represents a recycle ratio of an anonymous page and a file page, where the anonymous page (anonymous page) represents a page without a file background, such as a heap, a stack, a data segment, and the like, which does not exist in a file form and cannot be exchanged with a disk file. The file page (file page) represents a page with a file background, which is a cache generated by a memory after a file is read, and is generally called a file cache. For example, if the set memory recovery amount is 200, if the memory recovery parameter is 60, it indicates that the recovery ratio of the anonymous page and the file page is 60: 140.
The recovery strategy of the anonymous page is generally to compress the anonymous page and store the compressed anonymous page in a Random Access Memory (RAM), and because the process needs to use a Central Processing Unit (CPU) to compress the anonymous page and decompress the compressed anonymous page again when in use, the recovery process needs to consume a certain CPU time, and the process is relatively slow. The recovery strategy of the file page is generally divided into two types, if the file page is not modified, the content of the file page can be directly discarded; if the contents of a file page are modified, the contents need to be written back to disk, the file page discarded, and the file page read from disk again when in use. Therefore, in this embodiment, since the recovery process of the file page is faster than that of the anonymous page, the memory recovery parameter of the electronic device can be adjusted by increasing the recovery ratio of the file page to accelerate the memory recovery speed, thereby increasing the system performance.
For example, when the set memory recovery amount is 200, if the original memory recovery parameter is 60, the recovery ratio of the file page may be increased to decrease the memory recovery parameter, for example, the memory recovery parameter is adjusted to 50, and then the recovery ratio of the anonymous page and the file page is 50: 150. For another example, if the memory reclamation parameter is adjusted to 30, then the reclamation ratio between the anonymous page and the file page is 30: 170. The specific parameters for adjustment are not limited in this embodiment.
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 value is judged, and when the memory recovery times exceed the time threshold value, the memory recovery parameters of the electronic device are adjusted to accelerate the memory recovery speed, wherein the memory recovery parameters represent the recovery ratio of the anonymous page and the file page, so that when the sudden increase of the memory recovery times of the electronic device is detected, the memory recovery parameters of the electronic device are adjusted to accelerate the memory recovery speed, and the system performance is improved.
Referring to fig. 2, fig. 2 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 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, a Process Running in the foreground of the electronic device may be detected by Running Task, Running Process, Activity Lifecycle calls, Usage states Manager, Android-owned barrier-free function of the electronic device, or Process information stored in a directory in a Linux system kernel, or the like. 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 resource of the electronic device may be obtained and the memory resource 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 resource required by the target process by checking historical data or 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 three days, one week, one month, and the like, and is not limited herein, and taking the preset history period as three days, the memory resources occupied by the electronic device running the target process in the foreground each time in the history period of three days may be obtained, the average value of the memory resources occupied by the target process is calculated based on the memory resources occupied each time, and the average value is determined as the memory resources required by the target process.
Referring to fig. 3, fig. 3 is a flowchart illustrating the step S210 of the memory recycling method shown in fig. 2 according to the present application. As will be described in detail with respect to the flow shown in fig. 3, the memory recycling method may specifically include the following steps:
step S211: and when the electronic equipment runs a target process in a foreground, acquiring the type of the target process.
In this embodiment, when it is determined that the electronic device runs the target process in the foreground, the type of the target process may be acquired. As an implementable manner, the electronic device may create a mapping relationship between a plurality of process names and a plurality of process types in advance, where each process name in the plurality of process names may correspond to one process type in the plurality of process types, and one process type in the plurality of process types may correspond to one or more process names in the plurality of process names. For example, the plurality of process names includes: the process comprises a process name A, a process name B and a process name D, wherein the process types comprise: process type D and process type E, then the mapping relationship may include: the process name a-process type D, the process name B-process type E, the process name C-process type D, etc., which are not limited herein.
Further, when the electronic device runs the target process in the foreground, the package name of the target process may be obtained, the name of the target process is determined based on the inclusion of the target process, a process type corresponding to the process name consistent with the name of the target process is queried from the mapping relationship based on the name of the target process, and the process type is determined as the type of the target process. For example, when the name of the target process coincides with the process name a, then the type of the target process may be determined to be the process type D, when the name of the target process coincides with the process name B, then the type of the target process may be determined to be the process type E, and so on.
Step S212: and judging whether the type meets a preset type or not.
In some embodiments, the electronic device is preset with a preset type, and the preset type is used as a criterion for determining the type of the target process, so that after the type of the target process is obtained, the type of the target process may be compared with the preset type to determine whether the type of the target process satisfies the preset type. The number of the preset types can be one or more, when the number of the preset types is one, whether the type of the target process is consistent with the preset type or not can be judged, when the type of the target process is consistent with the preset type, the type of the target process can be determined to meet the preset type, and when the type of the target process is not consistent with the preset type, the type of the target process can be determined not to meet the preset type; when the number of the preset types is multiple, whether the type of the target process is consistent with any preset type in the multiple preset types or not can be judged, when the type of the target process is consistent with any preset type in the multiple preset types, the target process can be determined to meet the preset type, and when the type of the target process is inconsistent with the multiple preset types, the target process can be determined not to meet the preset type.
In some embodiments, the preset type may include a video playing type, a video processing type, and the like, which have a large demand on memory resources.
Step S213: and when the type meets the preset type, acquiring the residual memory resource of the electronic equipment and determining the memory resource required by the target process based on the type.
In some embodiments, when the type of the target process meets the preset type, it represents that the target process has a large demand for the memory resource, and therefore, sufficient memory resource needs to be idle in the electronic device to ensure normal operation of the target process, and therefore, the remaining memory resource of the electronic device can be obtained and the memory resource required by the target process is determined based on the type of the target process, so as to determine whether the remaining memory resource of the electronic device meets 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; 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 device 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 memory recovery parameter corresponding to the first time threshold.
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 memory recovery parameter corresponding to the first time threshold can be determined. In some embodiments, the electronic device may preset different times thresholds corresponding to different memory recycling parameters, for example, a first time threshold corresponding to a first memory recycling parameter, a second time threshold corresponding to a second memory recycling parameter, a third time threshold corresponding to a third memory recycling parameter, a fourth time threshold corresponding to a fourth memory recycling parameter, and the like. When the memory recovery parameter exceeds a first time threshold and does not exceed a second time threshold, representing that the memory recovery parameter corresponds to the first time threshold, and acquiring a first memory recovery parameter corresponding to the first time threshold; when the memory recovery parameter exceeds the second time threshold and does not exceed a third time threshold, representing that the memory recovery parameter corresponds to the second time threshold, and acquiring a second memory recovery parameter corresponding to the second time threshold; when the memory recovery parameter exceeds the third time threshold and does not exceed the fourth time threshold, representing that the memory recovery parameter corresponds to the third time threshold, and acquiring a third memory recovery parameter corresponding to the third time threshold; and when the memory recovery parameter exceeds the fourth time threshold, representing that the memory recovery parameter corresponds to the fourth time threshold, and acquiring the fourth memory recovery parameter corresponding to the fourth time threshold.
Therefore, in this embodiment, when the determination result indicates that the memory recycling time exceeds the first time threshold and does not exceed the second time threshold, the first memory parameter corresponding to the first time threshold may be determined.
Step S250: and adjusting the memory recovery parameter of the electronic equipment to be the first memory recovery parameter.
Further, after the first memory recovery parameter is obtained, the memory recovery parameter of the electronic device may be adjusted to the first memory recovery parameter, so as to accelerate the memory recovery speed. The memory recovery speed corresponding to the first memory recovery parameter is greater than the memory recovery parameter corresponding to the original memory recovery parameter of the electronic device. For example, when the set memory reclamation amount is 200, if the original memory reclamation parameter is 60, that is, the reclamation ratio of the anonymous page to the file page is 60:140, the first memory reclamation parameter may be 50, that is, the reclamation ratio of the anonymous page to the file page is 50:150, so as to accelerate the memory reclamation speed.
Step S260: and when the memory recovery times exceed the second time threshold value, determining a second memory recovery parameter corresponding to the second time threshold value, wherein the memory recovery speed corresponding to the second memory recovery parameter is greater than the memory recovery speed corresponding to the first memory recovery parameter.
When the judgment result indicates that the memory recovery times exceed the second time threshold, a second memory recovery parameter corresponding to the second time threshold can be determined. It should be noted that, in this embodiment, the memory recovery speed corresponding to the second memory recovery parameter is greater than the memory recovery speed corresponding to the first memory recovery parameter, that is, the larger the number threshold value that the number of times of memory recovery of the electronic device in the specified time period exceeds, the faster the memory recovery speed corresponding to the determined memory recovery parameter is, so that memory recovery can be accelerated, and system performance can be improved.
In some embodiments, if the electronic device is provided with a first time threshold, a second time threshold, a third time threshold and a fourth time threshold, and the first time threshold is less than the second time threshold and less than the third time threshold and less than the fourth time threshold, then the original memory recovery speed corresponding to the memory recovery parameter is less than the memory recovery speed corresponding to the first memory recovery parameter and less than the memory recovery speed corresponding to the second memory recovery parameter.
Step S270: and adjusting the memory recovery parameter of the electronic equipment to be the second memory recovery parameter.
Further, after the second memory recovery parameter is obtained, the memory recovery parameter of the electronic device may be adjusted to the second memory recovery parameter, so as to accelerate the memory recovery speed. And the memory recovery speed corresponding to the second memory recovery parameter is greater than the memory recovery parameter corresponding to the first memory recovery parameter of the electronic equipment. For example, when the set memory reclamation amount is 200, if the original memory reclamation parameter is 60, that is, the reclamation ratio of the anonymous page to the file page is 60:140, the first memory reclamation parameter may be 50, that is, the reclamation ratio of the anonymous page to the file page is 50:150, and the second memory reclamation parameter may be 40, that is, the reclamation ratio of the anonymous page to the file page is 40: 160.
In another embodiment of the present application, a memory recycling method is provided, where when an electronic device runs a target process in a foreground, acquiring remaining memory resources of the electronic device and determining memory resources required by the target process, when the remaining memory resources are smaller than the memory resources required by the target process, detecting a memory recycling frequency of the electronic device within a specified time period, determining whether the memory recycling frequency exceeds a frequency threshold, when the memory recycling frequency exceeds the first frequency threshold and does not exceed a second frequency threshold, determining a first memory recycling parameter corresponding to the first frequency threshold, adjusting a memory recycling parameter of the electronic device to the first memory recycling parameter, and when the memory recycling frequency exceeds the second frequency threshold, determining a second memory recycling parameter corresponding to the second frequency threshold, where a memory recycling speed corresponding to the second memory recycling parameter is greater than a memory recycling speed corresponding to the first memory recycling parameter, and adjusting the memory recovery parameter of the electronic equipment to be a second memory recovery parameter. 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 still another embodiment of the present application. 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 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.
