And step 304, determining the application running in the background as the application to be processed.

The terminal considers that the application running in the background needs to be processed, so the application running in the background is determined as the application to be processed.

It should be noted here that the number of the to-be-processed applications determined by the terminal is not necessarily only one, but may also be two or more, and as long as the background duration and the occupancy rate of the applications running in the background meet the determination conditions described in step 302, all the applications running in the background that meet the determination conditions are determined as the to-be-processed applications.

And 305, closing the application to be processed, and releasing the running memory occupied by the application to be processed.

To further illustrate the object of the present invention, the above embodiments are further illustrated.

Example two

Fig. 4 is a flowchart of a second embodiment of the method for clearing an operating memory according to the present invention, and as shown in fig. 4, the method for clearing an operating memory according to the embodiment of the present invention is applied to a smart phone, and the method may include the following steps:

step 401, setting a white list of applications running in the background.

The smart phone provides a white list of applications running in the background for a user, the user cleans the applications running in the background in the white list of the applications running in the background according to actual needs, and the applications running in the background do not need to be cleaned, and finally the smart phone generates a white list of the applications running in the background, and the applications in the white list of the applications running in the background are not influenced by cleaning; by setting the white list, the application in the white list cannot be cleaned, and the accuracy of cleaning the running memory can be further improved.

Step 402, judging whether the application running in the background is the application in the white list of the application running in the background.

The smart phone judges whether the application running in the background is an application in a white list of the application running in the background, and executes step 403 when the application running in the background is determined to be an application in the white list of the application running in the background; upon determining that the background-running application is not an application in the whitelist of background-running applications, step 404 is performed.

And step 403, ending the processing task.

And the smart phone finishes the current processing task and executes the current processing task according to the normal processing task flow.

And step 404, acquiring the background duration of the application running in the background and the occupancy rate of the running memory.

The smart phone acquires the background duration of the application running in the background and the occupancy rate of the running memory occupied by the application running in the background; the background duration of the application running in the background is the duration of the application running in the background detected in a time period lasting until the current moment after the operating system of the smart phone is started.

Step 405, judging whether the background time length exceeds a preset background time length and judging whether the occupancy rate exceeds a preset occupancy rate.

After acquiring the background time length applied to background operation and the occupancy rate of the occupied operation memory, the smart phone judges whether the background time length exceeds a preset background time length and judges whether the occupancy rate exceeds a preset occupancy rate, and executes step 406 when determining that the background time length does not exceed the preset background time length and/or the occupancy rate exceeds the preset occupancy rate (namely, only one of the background time length and the occupancy rate does not exceed a corresponding judgment object); and when the background time length is determined to exceed the preset background time length and the occupancy rate exceeds the preset occupancy rate, executing step 407.

Step 406, ending the processing task.

And 407, acquiring the starting times of the application running in the background.

The smart phone obtains the starting times of the application running in the background, wherein the starting times are the starting times from the starting of the operating system to the current time.

And step 408, processing the occupancy rate of the running memory occupied by the application running in the background and the starting frequency of the application running in the background to obtain a processed result.

The smart phone performs normalization processing aiming at the occupancy rate of the application running in the background for occupying the running memory and the starting times of the application running in the background, and the specific processing mode is as follows:

firstly, the smart phone processes the occupancy rate of the application running in the background occupying the running memory by utilizing a normalization mode to obtain the normalized occupancy rate, processes the starting times of the application running in the background by utilizing the normalization mode, and obtains the normalized starting times by taking the absolute value of the difference value between the starting times processed by utilizing the normalization mode and 1.

Secondly, the smart phone distributes a first weight coefficient for the normalized occupancy rate and a second weight coefficient for the normalized starting times, the sum of the first weight coefficient and the second weight coefficient is 1, and the first weight coefficient and the second weight coefficient are both larger than 0 and smaller than 1; it should be noted that, the specific first weight coefficient and the specific second weight coefficient may be set according to the actual requirement of the user, for example, if the occupancy rate of the operating memory of the user is more important, the first weight coefficient may be set to be larger than the second weight coefficient, and if the occupancy rate of the operating memory of the user is more important, the second weight coefficient may be set to be larger than the first weight coefficient.

And finally, the smart phone calculates to obtain a comprehensive weight value of the application running in the background, wherein the comprehensive weight value is the sum of the weight value of the normalized occupancy rate and the weight value of the normalized starting times, the weight value of the normalized occupancy rate is the product of the normalized occupancy rate and a first weight coefficient, and the weight value of the normalized starting times is the product of the normalized starting times and a second weight coefficient.

In the embodiment of the present invention, the normalization method includes, but is not limited to: a logarithmic function normalization method, an exponential normalization method, a trigonometric or inverse trigonometric function normalization method, or the like.

And step 409, judging whether the processed result meets a preset condition.

After obtaining the comprehensive weight value of the application running in the background, the smart phone may determine whether the comprehensive weight value of the application running in the background meets a preset condition, where the preset condition includes but is not limited to: the comprehensive weight value of the application running in the background is greater than the condition of the preset comprehensive weight value; the preset integrated weight value can be set according to the actual requirements of the user, and is not limited herein.

When it is determined that the processed result does not satisfy the preset condition, performing step 410; when it is determined that the processed result satisfies the preset condition, step 411 is performed.

By increasing judgment and comparison of comprehensive weighted values of applications running in the background, the comparison dimensionality is increased, the accuracy of cleaning running memories can be further improved, and the possibility of misoperation is reduced.

And step 410, ending the processing task.

And 411, determining the application running in the background as the application to be processed.

The smart phone considers that the application running in the background needs to be processed, so that the application running in the background is determined as the application to be processed.

It should be noted here that the smart phone determines that the to-be-processed application is not necessarily only one, but may also be two or more, and in the case of two or more, the implementation principle is the same as that in the case of one, and therefore, the details are not described here.

And step 412, closing the application to be processed, and releasing the running memory occupied by the application to be processed.

The smart phone closes the application to be processed determined in step 411, and releases the running memory occupied by the application to be processed, thereby achieving the purpose of cleaning the running memory of the smart phone.

According to the method for clearing the running memory, the white list of the application running in the background is set; judging whether the application running in the background is the application in a white list of the application running in the background; when the background running application is determined not to be the application in the white list of the background running application, acquiring the background duration of the background running application and the occupancy rate of the running memory; judging whether the background time exceeds a preset background time and judging whether the occupancy rate exceeds a preset occupancy rate; when it is determined that the background duration exceeds the preset background duration and the occupancy rate exceeds the preset occupancy rate, acquiring the starting times of the application running in the background; processing the occupancy rate of the application running in the background for occupying the running memory and the starting times of the application running in the background to obtain a processed result; judging whether the processed result meets a preset condition or not; when the processed result meets the preset condition, determining the application running in the background as the application to be processed; closing the application to be processed and releasing the running memory occupied by the application to be processed; the comparison of the background duration and the occupancy rate is added for the application running in the background, the starting times of the background application exceeding the preset background duration and the preset occupancy rate are processed, the processed result is obtained, and when the processed result meets the preset condition, the application running in the background is determined to be the application needing to be processed, so that the background application which a user does not want to close can be prevented from being closed, the accuracy and the intelligence of cleaning the running memory are improved, and the user experience can be effectively improved.

To further embody the purpose of the present invention, a scenario embodiment is further illustrated on the basis of the second embodiment.

Fig. 5 is a first schematic diagram of a scenario of a method for clearing running memory according to an embodiment of the present invention, and as shown in fig. 5, in a background of a smart phone, 4 applications run in the background, which are application a, application B, application C, and application D, respectively.

The white list of the background running application set by the user contains an application D, and does not contain an application A, an application B and an application C, so that the application D is removed when the running memory is cleared by the smart phone, and only the application A, the application B and the application C are processed.

Fig. 6 is a schematic view of a second scenario of the method for clearing an operating memory according to the present invention, and as shown in fig. 6, a smart phone obtains respective corresponding background durations and occupancy rates of the operating memory for an application a, an application B, and an application C, where the obtained contents are respectively: the background time of the application A is 5000 seconds, the occupancy rate of the occupied running memory is 12%, the background time of the application B is 7000 seconds, the occupancy rate of the occupied running memory is 18%, the background time of the application C is 8000 seconds, and the occupancy rate of the occupied running memory is 20%.

The preset background duration is 4000 seconds, the preset occupancy rate is 8%, and it is seen that the background durations and the occupancy rates of the application a, the application B and the application C all exceed the preset background duration and the preset occupancy rate, so that the smart phone continues to perform subsequent processing on the application a, the application B and the application C.

Fig. 7 is a third schematic view of a scenario of the method for clearing the operating memory according to the present invention, where as shown in fig. 7, the smart phone continues to obtain the start times of the application a, the application B, and the application C, the obtained start time of the application a is 5 times, the obtained start time of the application B is 15 times, and the obtained start time of the application C is 30 times.

Firstly, the smart phone normalizes the occupancy rates of an application A, an application B and an application C to obtain the corresponding normalized occupancy rates; specifically, the occupancy of each application is divided by the sum of the occupancy of application a, application B, and application C, and for application a: 12%/(12% + 18% + 20%) + 0.24, for application B: 18%/(12% + 18% + 20%) -0.36, for application C: 20%/(12% + 18% + 20%) -0.4; meanwhile, the smart phone performs normalization processing on the starting times of the application A, the application B and the application C to obtain respective corresponding normalized starting times; specifically, the starting times of the respective applications are divided by the sum of the starting times of the application a, the application B and the application C, and then the absolute value of the difference from 1 is taken, and for the application a: | 1- (5/(5+15+30) | 0.9, | 1- (15/(5+15+30) | 0.7 for application B, and | 1- (30/(5+15+30) | 0.4 for application C.

Secondly, the smart phone assigns a first weight coefficient of 0.6 to the normalized occupancy rates of the application a, the application B and the application C, and assigns a second weight coefficient of 0.4 to the normalized starting times of the application a, the application B and the application C.

Then, the smart phone calculates and obtains a neutralization weight value corresponding to each of the application A, the application B and the application C, wherein the comprehensive weight value is the sum of the weight value of the normalized occupancy rate and the weight value of the normalized starting times, the weight value of the normalized occupancy rate is the product of the normalized occupancy rate and a first weight coefficient, and the weight value of the normalized starting times is the product of the normalized starting times and a second weight coefficient; specifically, the comprehensive weight value for application a is: (0.24 × 0.6) + (0.9 × 0.4) ═ 0.504, the combined weight for application B is: (0.36 × 0.6) + (0.7 × 0.4) ═ 0.496, the combined weight for application C is: (0.4 × 0.6) + (0.4 × 0.4) ═ 0.4.

And finally, presetting the comprehensive weight value to be 0.45, determining the application A and the application B with the comprehensive weight value larger than 0.45 as the applications to be processed by the smart phone, closing the applications to be processed and releasing the running memory occupied by the applications to be processed.
