Description

Resource recovery control method, terminal and computer readable storage medium

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a resource recycling control method, a terminal, and a computer-readable storage medium.

Background

With the rapid development of mobile communication, the intelligent terminal product has functions of not only being a communication tool, but also being a tool for people to entertain. At present, people can use the intelligent terminal, or read, or play games, or chat no matter in what place. And as the intelligent terminal occupies an increasingly important role in life and work of people, the dependence of users on the intelligent terminal in life and work is more and more serious.

The intelligent terminal running the Android system and other related systems is divided into foreground applications and background applications, the number of the background applications cannot be unlimited due to the limitation of the size of the memory, and specifically, a plurality of background applications are reserved, and the reserved background applications are related to the current residual memory on one hand and the priority of the background applications (namely background APPs) on the other hand. The following description takes process recycling of the Android system as an example: the memory recovery of the Android system process is responsible for a LowMemory Killer (LMK), and the LMK killing process is as follows: when the remaining free memory of the system is lower than a certain threshold (for example 147MB), the target process with the maximum ADJ value is selected from the processes with the ADJ value larger than or equal to the corresponding threshold (for example 900), and the target process is sent signal 9 to kill the process. In the above process, in brief, each background APP has its own ADJ priority, and APPs with lower priorities are easier to be cleared.

For the resource recycling control scheme, whether the background APP is cleared depends on the ADJ priority of the background APP, the ADJ priority is weighted by four major components of the application, and the scheme has great rationality but ignores a point that the background application is suspended (in the background). For example, suppose that a user is editing a document with a mobile phone office word, and suddenly calls, the word is transferred to the background, and suppose that the application of the background is WeChat, SMS, etc. When resource recovery is needed, the office word is ranked lower according to the ADJ priority, and the office word is likely to be cleared, but obviously not wanted by the user; and assuming another scene, assuming that the user is recording things by using the mobile phone office word, and then the user changes the idea and wants to change the note book record, the user presses the home key to return to the desktop, selects the note book to open and starts editing, and then the word is transferred to the background, in which case the office word is in accordance with the user expectation if the office word is cleared by the mechanism. It can be seen that the resource recycling control mechanism is not accurate and reasonable enough for selecting which applications to clean the background, which results in poor user experience satisfaction.

Optionally, when the reason for switching an application to the background is passive switching, the higher the priority of the application or the video frequency, the smaller the corresponding weighted value.

Optionally, when the reason for switching an application to the background is passive switching, the smaller the memory occupied by the application is, the smaller the corresponding weighted value is.

Optionally, the active switching includes switching the indicated application to the background according to a switching instruction of the user.

Further, the touch panel 1071 may cover the display panel 1061, and when the touch panel 1071 detects a touch operation thereon or nearby, the touch panel 1071 transmits the touch operation to the processor 110 to determine the type of the touch event, and then the processor 110 provides a corresponding visual output on the display panel 1061 according to the type of the touch event. Although the touch panel 1071 and the display panel 1061 are shown in fig. 1 as two separate components to implement the input and output functions of the mobile terminal, in some embodiments, the touch panel 1071 and the display panel 1061 may be integrated to implement the input and output functions of the mobile terminal, and is not limited herein.

Based on the above terminal hardware structure and communication network system, the present invention provides various embodiments of the method.

First embodiment

The embodiment provides a resource recovery control method, which is characterized in that when a terminal resource recovery condition is detected to be triggered, the retention priority of each background application is determined according to the priority of each current background application and the weighted value corresponding to the reason why each background application is switched to the background; and then, removing the corresponding applications from the applications currently running in the background of the terminal according to the sequence of the reserved priorities from low to high, namely, taking the reason for switching the applications to the background as a factor on the one hand of whether the applications should be removed or not in a weighting mode, so that the rationality and the accuracy of selecting the target applications to be removed can be improved to a greater extent, and the user experience satisfaction is improved.

For ease of understanding, the present embodiment will be described below with reference to a process of a resource recycling control method as an example. Please refer to fig. 3, which includes:

s301: and detecting whether the terminal resource recovery condition is triggered.

In this embodiment, the mechanism for detecting whether the terminal resource recycling condition is triggered can be flexibly selected and set. For example, in one example, a mechanism for real-time detection may be employed. In another example, the detection may be at preset time intervals. For example, every 30 seconds, 1 minute, etc.

In this embodiment, the resource recovery condition may also be flexibly set. For example, in one example, the resource reclamation conditions may include, but are not limited to:

the current residual memory of the terminal is smaller than a preset memory threshold value; at this time, it is shown that when the number of application processes running on the terminal is too many and exceeds the maximum value of the memory capable of being loaded by the terminal, in the subsequent running process of the terminal, the situation that the terminal runs slowly or even is jammed due to insufficient redundancy of the current memory is likely to occur. In order to avoid the situation, the current residual memory of the visible terminal is smaller than a preset memory threshold value and is used as a trigger condition for resource recovery; however, it should be understood that the size of the preset memory threshold in this embodiment may be flexibly set according to the terminal memory configuration condition, the comprehensive performance of the terminal, the use habit of the user, and the like. And in some examples, a user can also be supported to dynamically set and update the preset memory threshold.

The current residual memory of the terminal does not meet the requirements of the current application to be operated; at this time, the current remaining memory of the terminal may not meet the condition that the current remaining memory is smaller than the preset memory threshold, but does not meet the requirement of the current application to be run, so that the running can be normally started after resource recovery processing is performed, and therefore, the condition that the current remaining memory of the terminal does not meet the requirement of the current application to be run can also be used as a condition for triggering resource recovery control.

It should be understood that the terminal resource reclamation conditions are not limited to the two cases of the above example. The terminal resource recovery condition can be flexibly set according to the actual application scene requirements, and in some examples, the user can also be supported to dynamically set and update the terminal resource recovery condition.

The terminal in this embodiment may be a mobile intelligent terminal such as a mobile phone, a tablet computer, a notebook computer, a palm computer, a PDA, a portable media player, an intelligent bracelet, an intelligent watch, or a fixed intelligent terminal such as a digital TV, a desktop computer, and a vehicle-mounted computer. The system run by the terminal in this embodiment may include various operating systems, which may include, but are not limited to, Android, iOS, windows phone, Symbian, BlackBerry OS, web OS, and windows mobile.

S302: and when detecting that the terminal resource recovery condition is triggered, acquiring the retention priority of each application currently running in the terminal background.

In this step, the retention priority of each application currently running in the background of the terminal (in this embodiment, these applications are referred to as background applications) is obtained, which is substantially different from the ADJ priority obtained in the background art. In this embodiment, the retention priority of each background application is determined according to the priority of each application itself and the weighted value corresponding to the reason why each application is switched to the background. The reason for switching the application to the background is taken as a factor on one aspect of whether the application should be cleared or not in a weighting mode, and the ADJ priority of the background application is not simply considered, so that the reasonability and the accuracy of selecting the target application to be cleared can be improved to a greater extent, and the user experience satisfaction is improved.

S303: and clearing the corresponding applications from the applications currently running in the background of the terminal according to the sequence of the reserved priorities from low to high.

It should be understood that, in this embodiment, the specific purging manner for purging the corresponding applications from the applications currently running in the background of the terminal in the order from low retention priority to high retention priority may also be flexibly set. For ease of understanding, several cleaning examples are described below.

The first method is as follows: and clearing the applications one by one, namely clearing the corresponding applications one by one from the applications currently running in the terminal background according to the sequence of the retention priority from low to high until the recovery condition of the terminal resources is relieved after clearing. If the background application is not cleared, judging whether the current memory surplus condition after one clearing enables the terminal resource recovery condition to be relieved, for example, whether the current memory surplus after the clearing is larger than a preset memory threshold value or whether the current memory surplus condition meets the requirement of the current application to be operated, if so, stopping clearing so as to avoid bad experience of a user caused by clearing excessive applications; if the terminal resource recovery condition is not released, the terminal resource recovery condition needs to be cleared continuously according to the rule.

In this exemplary manner, when the application with the lowest retention priority (or the retention priority cleared in the current clearing sequence) includes a plurality of applications, the applications may be cleared in sequence from large to small according to the occupied memory until the terminal resource recycling condition is released after the clearing.

For example, assume that there are 4 background applications in the current background running application: application A, application B, application C and application D; the ordering of the retention priorities for these 4 background applications is: the retention priority of A is higher than that of application B, the retention priority of application B is higher than that of application C, the retention priority of application C is equal to that of application D, and the memory occupied by application C is larger than that of application D.

In this exemplary embodiment, when the trigger of the terminal resource recycling condition is detected, one of the application C and the application D with the lowest retention priority is first selected to be cleared, since the memory occupied by the application C is larger than that occupied by the application D, the application C is first cleared, and then it is determined whether the current terminal resource recycling condition is removed after the application C is cleared, and if the condition is removed, the clearing is stopped. And if the terminal resource recovery condition is not released, continuing to clean the application D, then judging whether the current terminal resource recovery condition is released after the application D is cleaned, and if the current terminal resource recovery condition is released, stopping cleaning. And if the terminal resource recovery condition is not released, cleaning the application in the next level of retention priority according to the rule until the terminal resource recovery condition is released after the application is cleaned.

The second method comprises the following steps: and in a priority clearing mode one by one, after the retention priority of each background application is obtained from each application currently running in the background of the terminal, sequencing the retention priority of each background application, and clearing the applications corresponding to the corresponding retention priority one by one according to the sequence of the retention priority from low to high until the recovery condition of the terminal resources is relieved after clearing. At this time, if an application corresponding to the retention priority is not cleared, it is determined whether the current remaining memory condition after one clearing relieves the terminal resource recycling condition, for example, whether the current remaining memory condition after the clearing is greater than a preset memory threshold value or meets the requirement of the current application to be run, and if the current remaining memory condition after the clearing is greater than the preset memory threshold value, the clearing can be stopped, so as to avoid bad experience of the user caused by too many applications being cleared. If the terminal resource recovery condition is not released, the terminal resource recovery condition needs to be cleared continuously according to the rule.

For example, assume that there are 6 background applications in the current background running application: application A, application B, application C, application D, application E; the ordering of the retention priorities for these 4 background applications is: the retention priority of A is higher than that of the application B and the application E, the retention priority of the application B is equal to that of the application E and is higher than that of the application C, the retention priority of the application C is equal to that of the application D, and the memory occupied by the application C is larger than that of the application D.

In this exemplary manner, when it is detected that the terminal resource recovery condition is triggered, the application C and the application D with the lowest retention priority are directly cleared first without considering whether the memory occupied by the application C is large in application D, and the two applications are cleared together; this can improve the resource recovery efficiency. And after each application in the lowest retention priority is cleared, judging whether the current terminal resource recovery condition is cleared, and if the current terminal resource recovery condition is cleared, stopping clearing. And if the terminal resource recovery condition is not released, continuously cleaning each background application (namely the application B and the application E) in the next-level retention priority until the terminal resource recovery condition is released after cleaning.

It can be seen that the two exemplary cleaning methods have respective advantages, and thus can be flexibly selected according to requirements. And it should be understood that the manner of clearing in the present embodiment is not limited to the two manners exemplified above. But is flexibly set and updated according to the requirements.

By the resource recovery control method provided by the embodiment, when the triggering of the terminal resource recovery condition is detected, the priority of each current background application and the reason why each background application is switched to the background can be combined to determine the retention priority of each background application; and then, the corresponding applications are cleared from the applications currently running in the background of the terminal by adopting a flexible clearing mechanism according to the sequence of the retention priority from low to high, so that the reasonability and the accuracy of the selection of the target application to be cleared can be improved to a greater extent, and the user experience satisfaction is improved.

Second embodiment

For ease of understanding, the present embodiment will be described below with reference to a weight value setting example of a reason why an application is switched to the background.

In the present embodiment, the priority of an application is described by taking the ADJ priority as an example. In this example, the higher the ADJ value is applied, the lower the ADJ priority thereof, whereas the lower the ADJ value is, the higher the ADJ priority thereof, and the ADJ value is set to a value of 0 or more in this example. However, it should be understood that in some examples, when setting the ADJ value to be smaller, the ADJ priority thereof is lower, the ADJ value is larger, the ADJ priority thereof is higher, or the ADJ value may be smaller than 0, and a simple equivalent substitution may be made according to the example provided by the present embodiment.

In this embodiment, the reason why the application is switched to the background may include, but is not limited to: active switching and passive switching; wherein,

active switching includes, but is not limited to: and switching the indicated application to the background according to the switching instruction of the user.

Passive switching then includes, but is not limited to, at least one of the following:

the active switching comprises switching the indicated application to a background according to a switching instruction of a user;

the application running in a certain foreground occupies foreground resources by the application with higher priority and is forced to be switched to the background running.

It should be understood that the definition and determination manner of the active handover and the passive handover in this embodiment is not limited to the above exemplary manner, and the definition may be flexibly set according to the specific application requirement, and optionally, only user-defined setting or updating may be supported.

In this embodiment, the weighted value corresponding to the reason for switching the application to the background includes:

when the reason for switching a certain application to the background is active switching, the corresponding weighted value is 1; of course, the value may be set to be greater than 1 or less than 1 according to the requirement, as long as it is smaller than the corresponding weighted value when the reason that the application is switched to the background is passive switching.

When the reason for switching a certain application to the background is passive switching, the corresponding weighted value is a value smaller than 1; the specific value of the weighted value can be flexibly set. For each background application that is passively switched to the background, the weighted values corresponding to the background applications may be the same, for example, all the weighted values are set to 0.9, 0.8, 0.5, and the corresponding relationship at this time is shown in table one:

watch 1

Reason for handover	Weighted values
		Active handover	1
Passive switching	q (q is less than 1)

In this embodiment, for each background application that is passively switched to the background, a corresponding weighted value may also be flexibly set according to the characteristics of the specific background application itself. The characteristics may include, but are not limited to, the priority of the application itself, the video frequency of the application, the size of the resources occupied by the application, etc.

In one example, when the reason for an application to be switched to the background is a passive switch, the higher the priority of the application is, the smaller the corresponding weighted value is.

For example, assume that there are 4 background applications in the current background running application: the reason that the application a is switched to the background is active switching, the reason that the application B, the application C and the application D are switched to the background is passive switching, the priority of the application B is higher than that of the application C, and the priority of the application C is higher than that of the application D, and then a corresponding relationship at this time is shown in table two:

watch two

Applications of	Reason for handover	Weighted values
			Applications A	Active handover	1
Application B	Passive switching	0.8
			Applications C	Passive switching	0.85
Applications D	Passive switching	0.9

For another example, in an example, when the reason for an application to be switched to the background is passive switching, the higher the usage frequency of the application is, the smaller the weighting value corresponding to the application is, and at this time, the weighting value corresponding to the application changes with the change of the usage frequency of the application.

There are 4 background applications in the application that are still running in the current background: taking application a, application B, application C, and application D as examples, where the reason that application a is switched to the background is active switching, the reason that application B, application C, and application D are switched to the background is passive switching, the use frequency of application B is lower than that of application C, and the use frequency of application C is lower than that of application D, then a corresponding relationship at this time is shown in table three:

watch III

In an example, when the reason for switching an application to the background is passive switching, the smaller the memory occupied by the application is, the smaller the corresponding weighted value is, so that the application can be further prevented from being unreasonably cleared and reasonably retained, and the satisfaction of user experience is further improved.

There are 4 background applications in the application that are still running in the current background: taking an application a, an application B, an application C, and an application D as examples, where the reason that the application a is switched to the background is active switching, the reason that the application B, the application C, and the application D are switched to the background is passive switching, the occupied memory of the application B is lower than that of the application C, and the occupied memory of the application C is higher than that of the application D, then a corresponding relationship at this time is shown in table three:

watch III

Applications of	Reason for handover	Weighted values
			Applications A	Active handover	1
Application B	Passive switching	0.88
			Applications C	Passive switching	0.9
Applications D	Passive switching	0.89

In other examples of this embodiment, at least two of the self-priority, the occupied memory size, the frequency used by the user, and other characteristics of the background application may be combined to set a corresponding weighted value for the background application. However, when at least two of the weighted values are combined, the specific gravity of the weighted value can be set according to different characteristics, and the weighted value corresponding to the application is determined comprehensively according to the specific gravity of the weighted value.

It can be seen that, in this embodiment, for various background applications, when the reason for switching to the background is passive switching, a corresponding weighted value may be further set for each different background application according to at least one of the characteristics of the background application, such as its own priority, the size of the occupied memory, and the frequency used by the user, so that the control on the background applications is more refined, the rationality and accuracy for selecting the target application to be cleared in the resource recovery process can be further improved, and the satisfaction degree of the user experience is further improved.

Referring to fig. 4, the terminal in the present embodiment includes a processor 401, a memory 402, and a communication bus 403;

the communication bus 403 is used for realizing communication connection between the processor 401 and the memory 402;

The present embodiment also provides a computer-readable storage medium, which is applicable in various terminals, and which stores one or more programs, which are executable by one or more processors, to implement the steps of the resource recovery control method as exemplified in the above embodiments.

For convenience of understanding, in the present embodiment, a terminal is taken as an example, and a resource recycling control process is described as an example, with reference to fig. 5, the method includes:

s501: in the using process of the terminal, it is detected that the current residual memory of the terminal is smaller than a preset memory threshold value.

S502: and acquiring the retention priority of each application currently running in the background of the terminal. The retention priority is the product of the ADJ priority of each background application and the weighted value corresponding to the reason for switching each background application to the background.

S503: sequencing the background applications in sequence according to the sequence of the retention priority from low to high, and then clearing the corresponding background applications one by one according to the sequence of the retention priority from low to high until the current residual memory of the terminal is greater than or equal to a preset memory threshold value.

For convenience of understanding, in the present embodiment, taking a terminal as an example, a resource recycling control process of the terminal is described as an example, and referring to fig. 6, the resource recycling control process includes:

s601: in the using process of the terminal, the current residual memory of the terminal is detected to not meet the requirement of the current application to be operated.

S602: and acquiring the retention priority of each application currently running in the background of the terminal. The retention priority is the product of the ADJ priority of each background application and the weighted value corresponding to the reason for switching each background application to the background.

S603: sequencing all background applications in sequence according to the sequence of the retention priorities from low to high, and then clearing the background applications in the corresponding retention priorities step by step according to the sequence of the retention priorities from low to high (clearing the applications in one retention priority simultaneously) until the current residual memory of the terminal is detected to meet the requirements of the current applications to be operated.

It can be seen that, in the using process of the terminal, when resource recovery is required to be performed in detection, the corresponding target application can be reasonably selected from the acquired applications to be cleared according to the priority of each background application and the weighted value corresponding to the reason that each application is switched to the background, so that the reasonability and the accuracy of the selection of the target application to be cleared can be improved to a greater extent, and the satisfaction degree of user experience is improved.
