Please refer to the description of FIG. 2 for details.

FIG. 2 is a detailed flow chart of a method for applying wrong kill assessment (Wrong kill assessment) provided by an embodiment of the present application. The method for killing applications provided in the embodiments of the present application may be applied to electronic devices. The electronic device may be a terminal device such as a mobile phone or a tablet computer. The method for killing applications provided by this application improves the priority of applications used by users in daily use, so that the applications that users focus on will not be checked and killed, and the user experience of keeping alive is improved.

Specifically, the methods of killing applications include:

Step S11 , acquiring usage logs of application programs within a preset time period.

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

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

The application program background keep-alive log includes, but is not limited to, the application name of each application program in the N application programs, the package name (package_name), and the time each application program switches to the background each time (that is, each time it was previously The time when the platform is switched to the background) and the time when the foreground is switched each time (that is, the time when the application is started each time). N is a positive integer greater than or equal to 1.

The application program killing log includes, but is not limited to, the application name and package name of each application program, the killing time and killing reason of each application program.

Step S12, obtaining the killing time of each application program from the usage log of the application program, and determining the time when each application program switches to the background and switches to the foreground according to the killing time of each application.

In one embodiment, the time when the application program cuts to the background determined according to the killing time of each application program indicates the last time when the application program cuts to the background before the killing time. In one embodiment, the time when the application program switches to the foreground determined according to the killing time of each application program indicates the latest time when the application program switches to the foreground after the killing time.

In one embodiment, the killing time of each application can be obtained from the killing log of the application, and then the time and time for switching the background of each application are determined from the keeping alive log of the background of the application according to the killing time. Front desk time.

For example, referring to FIG. 3 , assuming that the killing time of the application A obtained from the killing log of the application program is T2, then it can be determined from the background keep-alive log of the application program according to the killing time T2 that the killing time is T2. Before the time T2, the last time when the application A switches to the background is T1, and after the killing time T2, the last time when the A application switches to the foreground is T3.

Step S13, calculate the time interval T corresponding to each application program according to the determined time when each application program switches to the background and switches to the foreground; determine the interval application number D corresponding to each application program within the time interval T.

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

In one embodiment, the interval application number D corresponding to each application program in the time interval T indicates the number of application programs switched to the foreground within the time interval T (that is, in the time interval T , the number of applications launched by the electronic device). In an embodiment, according to the time interval T, the interval application number D corresponding to each application program may be obtained from the application program background keep-alive log.

For example, still referring to FIG. 3 , suppose that the calculated time interval T=T3-T1 corresponding to application A; within the time interval T3-T1, two applications, application B and application C, are switched to the foreground respectively , therefore, the interval application number D corresponding to the A application is equal to 2.

Step S14, determine the evaluation result of each application program based on the time interval T corresponding to each application program, the number of applications D in the interval, and the basic score F of each application program.

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

In this embodiment, the calculation of the killing score S of each application includes: obtaining the first score Y1 of each application based on the time interval T corresponding to each application; The number of applications D obtains the second score Y2 of each application; and calculates the killing score S of each application according to the formula S=Y1*Y2*F.

In one embodiment, Y1=a1+b1*X+c1*X ² +d1*X ³ ; wherein, X=T; a1=206.841793563214; b1=-9.00021943093018; c1=0.134347573391717; d1=-0.000689371112453592.

In one embodiment, Y2=a2+b2*X+c2*X ² +d2*X ³ ; where X=D; a2=245.460539460545; b2=-47.6803759965558; c2=3.07527766351345; d2=-0.0655251611134173.

In one embodiment, multiple time intervals T can be set to correspond to different scores, the multiple time intervals T can be used as the abscissa in the XOY coordinate system, and the scores corresponding to the multiple time intervals T can be Values are plotted as ordinates in the XOY coordinate system, and these points are connected into a curve for trend fitting to obtain the curve function Y1.

In this embodiment, when setting the score value corresponding to the time interval T, the reference value of the time interval T can be set in advance, and the score value corresponding to the reference value is set to 100 points, which is less than the reference value. If the degree is enhanced, the score is increased, and if the user's sensitivity is greater than the reference value, the user's sensitivity is weakened, and the score is reduced. In addition, the boundary value of the time interval T can also be set. When the value of the time interval T is greater than the set boundary value, the user has no bad feeling. When the time interval T is greater than the set boundary value, the corresponding score is 0. In one embodiment, the base value of the time interval T is set to 15 minutes, and the boundary value of the time interval T is set to 60 minutes.

For example, referring to shown in Figure 4, the reference value of setting time interval T is 15 minutes, and the corresponding score is 100 minutes, and the boundary value of setting time interval T is 60 minutes; Setting time interval 5 minutes corresponds to score 160; Setting A time interval of 10 minutes corresponds to a score of 130, etc., and the multiple set time intervals T and the corresponding scores are used as coordinate points to draw points in the XOY coordinate system, and all the points drawn are connected into a curve for trend simulation Combined to obtain the curve function Y1.

In this embodiment, the fitting degree R ² between the obtained curve function Y1=a1+b1*X+c1*X ² +d1*X ³ and the curve obtained by actually plotting points can reach 0.999111278966183.

Similarly, a plurality of interval application numbers D can be set to correspond to different scores, and the plurality of interval application numbers D can be used as the abscissa in the XOY coordinate system, and the multiple interval application numbers D can be used to correspond to the scores respectively. Values are plotted as ordinates in the XOY coordinate system, and these points are connected into a curve for trend fitting to obtain the curve function Y2.

In this embodiment, when setting the score value corresponding to the interval application number D, the reference value of the interval application number D can be preset, and the score value corresponding to the reference value is set to 100 points, which is less than the reference value The higher the user's sensitivity, the higher the score, and the weaker the user's sensitivity, the lower the score. In addition, the boundary value of the interval application number D can also be set. When the value of the interval application number D is greater than the set boundary value, the user has no bad experience. When the interval application number D is greater than the set boundary value, the corresponding The score is 0. In one embodiment, the base value of the interval application number D is 4, and the boundary value of the interval application number D is set to 13.

For example, as shown in Figure 5, the reference value for setting the number of interval applications D is 4, the corresponding score is 100 points, and the boundary value for setting the number of interval applications D is 13; when the number of interval applications D is set to 2, it corresponds to The score value is 160; when the interval application number D is set to 3, the corresponding score value is 130, etc., and the multiple interval application numbers D and the corresponding scores are used as coordinate points in the XOY coordinate system to describe points, and all the described Connect the points into a curve for trend fitting to obtain the curve function Y2.

In this embodiment, the fitting degree R ² between the obtained curve function Y2=a2+b2*X+c2*X ² +d2*X ³ and the curve obtained by actually plotting points can reach 0.999165439224973.

In this embodiment, the basic score F of each application program can be set in advance. In one embodiment, the basic score F of each application program can be scored according to the user's usage habits.

In one embodiment, a table can be created that records the base score for each application. For example, referring to FIG. 6 , the form includes a plurality of fields, and the plurality of fields include, but are not limited to, the application name of each application, the basic score F, the category of each application (i.e. classification ), package name, etc.

For example, as shown in Figure 6, the basic score F of the "Glory of the King" application is set to 100 points according to the user's usage habits; the basic score F of the "QQ" application is set to 80 points.

In one embodiment, the application programs can also be sorted according to the killing score of each application program.

In one embodiment, a ranking table can be created to record the scoring ranking of the application program every time it is checked and killed.

For example, as shown in FIG. 8, the ranking table includes multiple fields, such as the serial number (SN) of the electronic device, the package name of the application, the time when the application was switched to the background, the time when the application was switched to the foreground, the reason for the application to be checked and killed, The time when the application was checked and killed, the interval time T (minutes), the number of applications in the interval D (pieces), the name of the application, the basic score F, the application classification, and the killing score (scoring data). As shown in Figure 8, the " ^WeChatTM " application was switched to the background at the time point "2021-04-24 20:40:38", and was killed at the time point "2021-04-24 20:40:38", and then Switch to the front desk at the time point "2021-04-24 ^20:40:42 " as an example. 40:42" interval application number is 0, then according to the calculation method of the killing score S provided in this case, it can be calculated that the killing score of the " ^WeChatTM " application is 5.0616 million points.

Step S15 , when the remaining memory of the electronic device is less than a preset value, the application program is checked and killed according to the evaluation result of each application program, so as to improve the user's experience of keeping alive the application program.

In one embodiment, when checking and killing applications according to the evaluation result of each application program, priority may be given to killing applications with lower checking and killing scores. That is, the higher the killing score, the higher the possibility of manslaughter.

In one embodiment, a first threshold (for example, 30 points) can also be set, and if the remaining memory of the electronic device is less than the preset value, priority will be given to killing applications whose killing scores are lower than the first threshold.

In this embodiment, it is also possible to dynamically schedule and analyze the killing reasons of the applications killed by the electronic device within a preset time period in the background. Specifically, a second threshold such as 80 points may be set, and attention may be paid to the reasons for killing applications whose killing scores exceed the second threshold (for example, the killing of applications whose killing scores exceed the second threshold application optimization, etc.), and execute a set of expert systems in the background to limit the way of killing applications exceeding the second threshold, further improving the actual experience of users. The application killing method provided by the embodiment of the present application can prevent the application from being detected and killed by mistake, improve the accuracy of the application killing, and ensure enough memory to ensure the stable operation of the operating system or the foreground application.
