detailed description

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present invention.

Embodiments of the present invention provide a method and device for closing an application program. The details will be described respectively below.

Embodiment one,

This embodiment will be described from the perspective of closing an application program. Specifically, the closing of an application program may be integrated in a terminal, and the terminal may be a device such as a smart phone or a tablet computer.

A method for closing an application program, comprising: setting a function level for a function in an application program; receiving a first function closing request triggered by a user's first operation on a terminal, the first function closing request carrying a first function corresponding to the first operation Operation information: obtain the corresponding first objective function level according to the first function closing request; close the corresponding function in the application program according to the first objective function level.

As shown in Figure 1, the application closing method, the specific process can be as follows:

101. Set the function level for the functions in the application program.

Specifically, the application program may be an application program running in the background, such as WeChat, QQ, etc. running in the background; generally, when writing a program that can run on an operating system, a main function is required. The main function means to establish an independent process, and this process becomes the entry point of the program, and calls other sub-functions (called methods in some OOP languages, such as Java). Of course, other called sub-functions can also be Then call more functions, so that the running track of the entire program is like a kind of stack, which can be called the call stack. The main function is both the entry and the exit of the program. Usually, an exit code can be specified before exiting to indicate the final result of the program.

Since the main function shoulders the heavy responsibility of entry and exit, in order to maintain and expand, the main function should be as concise as possible, and the specific implementation details can be encapsulated in the called sub-function. Therefore, when setting the function level for the functions in the application program, the function level can be set based on the calling relationship between the functions in the application program; that is, the step "setting the function level for the functions in the application program" can specifically include:

Obtain the call relationship between functions in the application;

Sets the function level for functions in the application according to this call relationship.

For example, the main function can be set as a first-level (highest-level) function, the sub-function directly called by the main function can be set as a second-level function, and the sub-function directly called by the second-level function can be set as a third-level function. Set the sub-function directly called by the third-level function as a fourth-level function, and so on; or, it can be arranged in reverse order, assuming there are three levels of functions, then the main function can be set as a third-level (highest level) function, Set the sub-function directly called by the main function as the second-level function, and set the sub-function called by the second-level function as the first-level function.

In the specific implementation process, the function level in the application can be expressed in many ways, for example, the function level can be indicated in the form of numbers, letters, etc.; taking the number form as an example, for example, 1 represents the first-level function, and 2 represents the function level. The second-level function, 3 represents the third-level function, where the larger the number, the higher the level, or the smaller the number, the higher the level, and so on.

102. Receive a first function closing request triggered by a user's first operation on the terminal, where the first function closing request carries first operation information corresponding to the first operation.

Specifically, the first operation may be a user's touch operation such as pressing or tapping on the terminal device. Correspondingly, the first operation information may be information such as pressing force and pressing frequency, or information such as the number of times of tapping and the location of tapping. The location of the touch may not be limited to the display screen of the terminal, but may also be the back, side and other parts of the terminal, which is not specifically limited in the present invention.

For example, taking the pressing operation on the terminal display screen as an example, in order to avoid misuse, the pressing pressure value corresponding to the pressing operation can be evaluated to determine whether the condition is met. If the condition is met, the first function can be triggered to close the request, or That is, the specific process of the step "receiving the first function shutdown request triggered by the user's first operation on the terminal" may be as follows:

Receive the user's pressing operation on the terminal;

Obtain the pressing pressure value corresponding to the pressing operation;

judging whether the pressing pressure value is greater than a preset threshold;

If greater than, trigger the first function to close the request.

103. Acquire a corresponding first objective function level according to the first function closing request.

Specifically, the first preset function level can be preset. For example, an editable selection interface can be provided for the user, and a sliding control can be set on the interface for slidingly displaying the function level. Set the level of the first objective function, such as can be set to level two, and then save. After the function closing request is triggered, the terminal can send an acquisition request, call the relevant process, obtain the relevant data of the set first objective function level from the corresponding storage area, and return the data to the terminal to obtain the first objective function The level is secondary.

Preferably, the corresponding first objective function level can be obtained based on the above operation information. For example, taking the first operation as a tap operation and the first operation information as the number of taps as an example, a mapping between the number of taps and the function level can be established in advance. Different tap times correspond to different function levels to obtain a mapping relationship set, and the corresponding first objective function level is obtained according to the mapping relationship set.

104. Close a corresponding function in the application program according to the first target function level.

In practical applications, the application program may be preset by the user and can be automatically processed as a preset application program. Whether the application program is a preset application program; that is, before closing the corresponding functions in the application program according to the first objective function level, it may also include:

Obtain the application ID of the application;

Judging whether there is a sample application identifier identical to the application identifier in the preset identifier set;

If yes, execute the corresponding function in the application program according to the level of the first objective function.

In order to reduce the power consumption of the terminal while keeping the application running normally, the first objective function level can be set lower than the highest function level, so as to keep the main function of the application from being closed; and when closing the corresponding function, While shutting down the functions at the first target level, other lower-level functions can also be shut down, that is, the specific process of the step "closing the corresponding functions in the application according to the first target function level" can be as follows:

judging whether the first objective function level is the lowest function level;

If so, then close the function corresponding to the first objective function level in the application program;

If not, close the functions corresponding to the first objective function level in the application program, and the functions whose function levels are lower than the first objective function level.

For example, taking the highest level as an example, the application program corresponds to a level-1 function, a level-2 function, a level-3 function, a level-4 function, and a level-5 function (the lowest level). Assuming that the level of the first objective function is level-5, it is easy It is obtained that the objective function level is the lowest function level, and at this time, the fifth-level function is closed; assuming that the first objective function level is four-level, the fourth-level function and the fifth-level function can be closed together.

In order to further reduce the power consumption of the terminal, the terminal may be further operated to close the remaining functions; that is, after closing the corresponding functions in the application program according to the first objective function level, the following steps may also be included:

receiving a second function closing request triggered by a user's second operation on the terminal, where the second function closing request carries second operation information corresponding to the second operation;

Acquiring a corresponding second objective function level according to the second operation information, where the second objective function level is higher than the first objective function level;

The corresponding remaining unclosed functions in the application program are closed according to the second objective function level.

For example, taking the highest level as an example, the application program corresponds to a level-1 function, a level-2 function, a level-3 function, a level-4 function, and a level-5 function (the lowest level). If the level of the first objective function is level-5, then The fifth-level function has been closed. Assuming that the second objective function level is the first-level function, the first-level function (ie, the main function) can be closed, and all remaining functions can also be closed at the same time.

Optionally, the specific flow of the step "closing the corresponding remaining unclosed functions in the application according to the level of the second objective function" may be as follows:

judging whether the second objective function level is the highest function level;

If so, close all remaining unclosed functions in the application;

If not, close the functions corresponding to the second objective function level among the remaining unclosed functions, and the functions whose function levels are lower than the second objective function level.

In practical applications, in order to keep the application running normally and reduce the power consumption of the terminal, it is possible to close the functions whose function level is higher than the first objective function level and lower than the highest function level in the remaining functions, for example, still use the highest Take level one as an example, the application program corresponds to functions of level one, level two, level three, level four, and level five (the lowest level). If the level of the first objective function is level five, the level five functions are already is closed, assuming that the level of the second objective function is three, then the third-level function and the fourth-level function can be closed.

Preferably, in order to further reduce the power consumption of the terminal, all the remaining functions can be closed to close the corresponding application; that is, when judging that the second target function is not at the highest function level, and closing the corresponding remaining unused functions in the application After closing the function, you can also include the following steps:

receiving a third function closing request triggered by a user's third operation on the terminal, where the third function closing request carries third operation information corresponding to the third operation;

Obtaining a corresponding third objective function level according to the third function closing request, where the third objective function level is higher than the second objective function level;

Closes all remaining unclosed functions in the application.

For example, taking the highest level as an example, the application program corresponds to a level-1 function, a level-2 function, a third-level function, a fourth-level function, and a fifth-level function (the lowest level). If the second objective function level is level-4, the first level The objective function level is level 5. At this time, the level 4 and level 5 functions have been closed. Assuming that the level 3 objective function is level 1, all remaining unclosed functions in the application can be closed, including level 1 functions, level 2 First-level function, third-level function; assuming that the third target function level is third-level, it is still possible to close all remaining unclosed functions in the application program, including first-level functions, second-level functions, and third-level functions.

As can be seen from the above, the method for closing an application program provided by the embodiment of the present invention adopts setting a function level for a function in the application program, and then receiving a first function closing request triggered by the user through a first operation on the terminal. The function closing request carries first operation information that the user performs a first operation on the terminal, obtains a corresponding first target function level according to the first function closing request, and closes a corresponding function in the application program according to the first target function level; This solution can close the corresponding functions in the application program based on the user's operation on the terminal, which can reduce the power consumption of the terminal, and because the solution does not directly close the application program, but closes the corresponding function in the application program, therefore, when it is necessary to restart When starting the application program, it is only necessary to call and execute the closed function again. Compared with the prior art, the restart speed of the application program can be improved while reducing the power consumption of the terminal.

Embodiment two,

According to the method described in Embodiment 1, an example will be given below for further detailed description.

In this embodiment, it will be described in detail by taking the application program closing device integrated in the mobile terminal, the application program running in the background as WeChat, and the highest function level as Level 1 as an example.

It should be noted that, in this embodiment, the functions corresponding to WeChat include first-level (highest level) functions, second-level functions, third-level functions, fourth-level functions, and fifth-level (lowest level) functions.

As shown in Figure 2, a method for closing an application program, the specific process may be as follows:

201. The mobile terminal sets a function level for a function in an application program.

Specifically, when setting the function level for the functions in the application program, the function level can be set based on the call relationship between the functions in the application program; that is, the step "setting the function level for the functions in the application program" can specifically include :

Obtain the call relationship between functions in the application;

Sets the function level for functions in the application according to this call relationship.

For example, the main function can be set as a first-level function, the sub-function directly called by the main function can be set as a second-level function, the sub-function directly called by the second-level function can be set as a third-level function, and the third-level function can be set as a function. The sub-function directly called by the function is set as a fourth-level function, and so on.

In the specific implementation process, the function level in the application can be represented in various forms. For example, the function level can be indicated in digital form, such as 1 for a first-level function, 2 for a second-level function, and 3 for a third-level function. Alternatively, the function level can be indicated in the form of letters, such as A for the first-level function, B for the second-level function, C for the third-level function, and so on.

202. The mobile terminal receives a first function closing request triggered by a first user operation, and closes a function of the lowest function level in the application program according to the first function closing request.

Specifically, the first operation may be a user's touch operation such as pressing or tapping on the terminal device. In order to avoid misoperation, the first function closing request may carry the first operation information corresponding to the first operation, such as pressing pressure , number of taps, etc.

In order to avoid misoperation and trigger the first function closing request, the operation information can be judged. Taking the number of taps as an example, it can be judged whether the number of taps meets the preset conditions, for example, whether the taps are two consecutive taps Tapping, specifically, it can be judged whether the number of taps is two consecutive taps, and if so, then judge whether the time interval between the two taps is less than the preset time interval, and if it is less, it is judged as two consecutive taps , at this time, the first function may be triggered to close the request.

In the specific implementation process, after receiving the first function closing request, an acquisition instruction can be sent, and the terminal can acquire the function at the function level corresponding to the first function acquisition request according to the acquisition instruction to close it. In this embodiment, it is set to Functions at the lowest function level, the first-class functions.

Preferably, before closing the first-level function, the application (ie WeChat) corresponding to the first-level function can also be judged to determine whether it is a preset application that can be automatically processed; for example, the application can be obtained (i.e. WeChat) application ID, judge whether there is a sample application ID identical to the application ID in the preset ID set, and if it exists, it is determined that WeChat is the default application program. At this time, the first-level function corresponding to WeChat can be to close.

203. The mobile terminal receives the second function closing request triggered by the user's second operation, and closes the functions whose function level is higher than the lowest function level and lower than the highest function level in the application program according to the second function closing request, and the following levels The function.

Specifically, the function level corresponding to the second function closing request can be preset by the user, and can be any one of level two, level three, and level four. There can be many kinds of functions, for example, you can close the third-level function, the fourth-level function, or the second-level function, the third-level function, and the fourth-level function, but not the second-level function and the fourth-level function.

204. The mobile terminal receives a third function closing request triggered by a third operation of the user, and closes all remaining functions in the application according to the third function closing request.

For example, if the mobile terminal closes the second-level function and the third-level function correspondingly according to the second function closing request, then after receiving the third function closing request, it can close all the remaining functions corresponding to WeChat, that is, the first-level function and the second-level function .

As can be seen from the above, the method for closing the application program provided by the embodiment of the present invention uses the mobile terminal to set the function level of the function in the application program, and then receives the first function closing request triggered by the first operation of the user, and then according to the first function The closing request closes the function at the lowest function level in the application, and then receives the second function closing request triggered by the user's second operation, and closes the function level in the application according to the second function closing request. Functions at the function level, and functions at the lower level, finally receive the third function closing request triggered by the user's third operation, and close all remaining functions in the application according to the third function closing request; The operation closes the corresponding function in the application program instead of directly closing the application program. Compared with the prior art, it can increase the speed of restarting the application program while reducing the power consumption of the terminal.
