Fig. 1 is a schematic flow chart of a method for applying a false kill assessment (Wrong kill assessment) provided in an embodiment of the present application. Referring to fig. 1, in the process of using a mobile phone by a user, various reasons of the searched and killed application are collected by the application killing method provided by the embodiment of the application, the mistaken killing of the application program is evaluated by the application killing method, and the searching and killing strategy is dynamically modified according to the evaluation result to improve the user keep-alive experience. For details, please refer to the description of fig. 2.

The application killing method provided by the embodiment of the application can be applied to electronic equipment. The electronic equipment can be terminal equipment such as a mobile phone and a tablet personal computer. By the application killing method, the priority of daily application use of the user is improved, the application which the user focuses on cannot be killed, and the keep-alive experience of the user is improved.

Specifically, the application killing method comprises the following steps:

step S11, acquiring a use log of the application program in a preset time period.

In one embodiment of the present application, the preset time period may refer to a time period of different durations such as the last 1 day or several days or a week or a month of the user. In one embodiment, the preset time period may be set in response to a user input.

In one embodiment of the application, the usage log of the application includes an application background keep-alive log and an application killing log.

The application background keep-alive log includes, but is not limited to, an application name, a package name (package _ name), a time for each application to switch to the background (i.e., a time for each switch from foreground to background), and a time for each switch to the foreground (i.e., a time for each start of an application) for each of the N applications. N is a positive integer greater than or equal to 1.

The application program searching and killing log comprises, but is not limited to, an application name, a package name, searching and killing time and searching and killing reason of each searched and killed application program.

In one embodiment, the time of application foreground cut determined from the time of kill of each application represents the time of the most recent application foreground cut after the time of kill.

In one embodiment, the killing time of each application program can be obtained from the application program killing log, and then the background switching time and foreground switching time of each application program are determined from the application program background keep-alive log according to the killing time.

For example, referring to fig. 3, assuming that the killing time obtained from the application killing log to the application a is T2, the application background keep-alive log may determine, according to the killing time T2, that the time of the application a last switching to the background before the killing time T2 is T1, and that the time of the application a last switching to the foreground after the killing time T2 is T3.

S13, calculating a time interval T corresponding to each application program according to the determined time for switching the background and the time for switching the foreground of each application program; and determining the interval application number D corresponding to each application program in the time interval T.

In this embodiment, the time interval T corresponding to each application program is equal to the difference between the determined foreground switching time and the determined background switching time of each application program.

In one embodiment, the interval application number D corresponding to each application program in the time interval T represents the number of application programs that are switched to the foreground in the time interval T (i.e., the number of application programs started by the electronic device in the time interval T). In one embodiment, the interval application number D corresponding to each application program can be obtained from the application program background keep-alive log according to the time interval T.

For example, still referring to fig. 3, assume that the time interval T = T3-T1 corresponding to the a application is calculated; in the time interval T3-T1, two applications, i.e., the B application and the C application, are respectively switched to the foreground, and therefore, the number D of interval applications corresponding to the a application is equal to 2.

In this embodiment, the determining the evaluation result of each application includes: and calculating the killing score S of each application program.

In this embodiment, the calculating the killing score S of each application includes: obtaining a first score Y1 of each application program based on the time interval T corresponding to each application program; obtaining a second score Y2 of each application program based on the interval application number D corresponding to each application program; and calculating the killing score S of each application program according to the formula S = Y1Y 2F.

In one embodiment, Y1= a1+ b 1X + c 1X ² +d1*X ³ (ii) a Wherein, X = T; a1=206.841793563214; b1= -9.00021943093018; c1=0.134347573391717; d1= -0.000689371112453592.

In this embodiment, when the score corresponding to the time interval T is set, a reference value of the time interval T may be set in advance, and the score corresponding to the reference value may be set to 100 points, so that the user's sensitivity is increased when the score is smaller than the reference value, and the user's sensitivity is decreased when the score is larger than the reference value. In addition, a boundary value of the time interval T may be set, and when the value of the time interval T is greater than the set boundary value, the user does not feel bad, and the corresponding score is set to 0 when the time interval T is greater than the set boundary value. In one embodiment, the reference value for the time interval T is set to 15 minutes and the boundary value for the time interval T is set to 60 minutes.

For example, referring to fig. 4, the reference value of the time interval T is set to 15 minutes, the corresponding score is 100 minutes, and the boundary value of the time interval T is set to 60 minutes; setting a time interval of 5 minutes corresponding to the score 160; setting time intervals of 10 minutes corresponding to scores 130 and the like, drawing points in an XOY coordinate system by taking a plurality of set time intervals T and the corresponding scores as coordinate points, and connecting all the drawn points into a curve to perform trend fitting to obtain a curve function Y1.

In the present embodiment, the obtained curve function Y1= a1+ b1 × X + c1 × X ² +d1*X ³ Degree of fitting R between curves obtained by actual plotting ² Reach 0.999111278966183.

Similarly, the curve function Y2 may be obtained by setting a plurality of interval application numbers D corresponding to different scores, respectively, plotting points with the interval application numbers D as abscissa in the XOY coordinate system and the scores corresponding to the interval application numbers D, respectively, as ordinate in the XOY coordinate system, and connecting the points into a curve for trend fitting.

In this embodiment, when the score corresponding to the interval application number D is set, a reference value of the interval application number D may be set in advance, and the score corresponding to the reference value may be set to 100, so that the user's perceptibility is increased when the score is smaller than the reference value, and the user's perceptibility is decreased when the score is larger than the reference value, and the score is decreased. In addition, a boundary value of the interval application number D may be set, and when the value of the interval application number D is greater than the set boundary value, the user does not feel bad, and the score value corresponding to the interval application number D greater than the set boundary value is set to 0. In one embodiment, the reference value of the interval application number D is 4, while the boundary value of the interval application number D is set to 13.

For example, referring to fig. 5, the reference value of the interval application number D is set to 4, the corresponding score is 100, and the boundary value of the interval application number D is set to 13; setting the interval application number D as 2, and corresponding to the score 160; setting interval application number D as 3, corresponding to scores 130 and the like, taking the interval application numbers D and the scores corresponding to the interval application numbers D as coordinate points to trace points in an XOY coordinate system, and connecting all the traced points into a curve to perform trend fitting to obtain a curve function Y2.

In the present embodiment, the obtained curve function Y2= a2+ b 2X + c 2X ² +d2*X ³ Degree of fit R between curves obtained from actual tracing points ² Can reach 0.999165439224973.

In the present embodiment, the base score F of each application program may be set in advance. In one embodiment, the base score F for each application may be scored according to user usage habits.

In one embodiment, a table may be created with which the base score, F, for each application is recorded. For example, referring to FIG. 6, the table includes a plurality of fields including, but not limited to, an application name for each application, a base score F, a category (i.e., classification) for each application, a package name, and the like.

For example, referring to fig. 6, the basic score F of the "royal glory" application is set to 100 according to the user's usage habit; the base score F for the "QQ" application was set to 80.

In one embodiment, the applications may also be sorted according to the kill score of each application.

In one embodiment, a ranking table may be created to record the scoring ranking each time an application is killed.

For example, referring to fig. 8, the ranking table includes a plurality of fields, such as Serial Number (SN) of the electronic device, package name of the application, background-cut time of the application, foreground-cut time, reason why the application is killed, time when the application is killed, time interval T (minutes), number of applications interval D (number), application name, base score F, application classification, and killing score (scoring data). According to FIG. 8, with "WeChat ^TM "application" in the background "at time point" 2021-04-24 "and at time point" 2021-04-24 "the ^TM The number of application intervals during the "application time points" 2021-04-24 "to" 2021-04-24 "40 is 0, and can be calculated according to the method for calculating the killing score S provided in the present application:WeChat TM "application has a kill score of 506.16 ten thousand.

And S15, when the residual memory of the electronic equipment is smaller than a preset value, searching and killing the application programs according to the evaluation result of each application program so as to improve the keep-alive experience of the user on the application.

In one embodiment, when the application program is killed according to the evaluation result of each application program, the killing may be prioritized for the application program with the lower killing score. I.e., the higher the kill score, the higher the likelihood of a false kill.

In an embodiment, a first threshold (for example, 30 points) may also be set, and if the remaining memory of the electronic device is smaller than the preset value, the application program with the killing score value lower than the first threshold is preferentially killed.

In this embodiment, the searching and killing reasons of the applications searched and killed by the electronic device within the preset time period can be dynamically scheduled and analyzed in the background. Specifically, a second threshold value, for example, 80 points, may be set, the cause of the application to be killed that has the killing score exceeding the second threshold value is concerned (for example, the application to be killed that has the killing score exceeding the second threshold value may be optimized, etc.), and a set of expert systems is executed in the background to limit the way of killing the application exceeding the second threshold value, so as to further improve the actual experience of the user. By the application killing method, the application can be prevented from being mistakenly checked and killed, the application checking and killing accuracy is improved, and sufficient memory is ensured to ensure the stable operation of an operating system or foreground application.
