The embodiment of the present disclosure provides a method for determining a foreground and background state of an application, as shown in fig. 1, the method includes:
step S101: acquiring the value of a preset variable mark, wherein the preset variable mark is updated in real time based on the visible state and the invisible state of each page of the application program;
step S102: and determining the foreground and background states of the application program according to the value of the preset variable mark.
For the embodiment of the present disclosure, the execution subject of the method may be a terminal device, such as a mobile terminal, or may also be an application installed on the terminal device. In practical applications, the mobile terminal may include devices such as a mobile phone, a smart phone, a tablet computer, a notebook computer, a personal digital assistant, a portable multimedia player, a navigation device, and the like. It will be understood by those skilled in the art that the configuration according to the embodiments of the present disclosure can be applied to a fixed type terminal such as a digital television, a desktop computer, etc., in addition to elements particularly used for mobile purposes.
Specifically, in a feasible implementation manner, a manner of updating the preset variable flag in real time based on the visible state and the invisible state of each page of the application program includes:
when a first page in the application program enters a visible state, executing addition processing on a preset variable mark;
and when the second page in the application program enters an invisible state, executing subtraction processing on the preset variable mark.
Typically, the interface that a user sees in an application can be viewed as a specific page. For example, the interface currently seen by the user is the a page, a new interface can be entered by clicking a certain button or link of the a page, which is displayed as the B page, and the a page is equivalent to being covered. If the return button of the B page is clicked, the A page can be returned again, and the B page is closed. If the user clicks a certain button or link of the page B, a new interface can be entered, namely the displayed page C, and the page B is equivalent to being covered, and so on.
In the embodiment of the present disclosure, when the first page in the application program enters the visible state, an addition process is performed on the preset variable flag, that is, 1 is added to the value of the current preset variable flag. Wherein the first page entering the visible state includes any one of:
(1) opening the first page
Specifically, the first page is opened and the first page is in a visible state. In the embodiment of the present disclosure, every time a page is opened, an addition process is performed on the preset variable flag.
In practical application, pages can be opened under the conditions of opening an application program, opening a screen locking interface and the like.
(2) Jumping from other pages to the first page
Specifically, when jumping to the first page from another page, which is equivalent to opening the first page, the first page enters a visible state.
In practical applications, the page before the jump is equivalent to be covered, and may be in a pause state, that is, an invisible state, and it is necessary to perform a subtraction process on the preset variable flag with respect to the page before the jump.
(3) Returning to the first page from other pages opened in the first page
Specifically, returning to the first page from other pages is equivalent to re-opening the first page, and the first page enters a visible state.
In practical application, after returning to the original page, the other page is equivalently closed and will be in a closed state, that is, an invisible state, and it is necessary to perform a subtraction process on the preset variable flag for the other page.
In the embodiment of the present disclosure, when the second page in the application program enters the invisible state, a subtraction process is performed on the preset variable flag, that is, 1 is subtracted from the current value of the preset variable flag. Wherein the second page entering the invisible state includes any one of the following:
(1) close the second page
Specifically, the second page is closed, and the second page is in the invisible state. In the embodiment of the present disclosure, every time a page is closed, a decrement process is performed on the preset variable flag.
In actual application, the page may be closed when the application program is closed, the home key (start key) is clicked and returned to the desktop of the terminal device, and the screen is locked.
(2) Opening other pages in the second page
Specifically, if another page is opened in the second page, and the second page is equivalent to being covered, the second page enters an invisible state.
In practical application, a new page opened in an original page is in a visible state, and an addition process needs to be performed on a preset variable flag for the new page.
(3) Opening other applications on the second page
Specifically, opening other applications on the second page may cause the second page to enter a suspended state, that is, the second page enters an invisible state.
In the embodiment of the present disclosure, the first page and the second page may be any page in an application program, where "first" and "second" merely distinguish names of the pages and cannot be understood as limitations on page order or content, and in practical applications, the first page and the second page may be the same page, for example, when one page is opened, an addition process is performed on a preset variable flag, the page is closed, and then a subtraction process is performed on the preset variable flag. Alternatively, the first page and the second page may be different pages, for example, when the second page is opened from the first page, the first page enters the invisible state and needs to perform a subtraction process on the preset variable flag, and when the second page enters the visible state and needs to perform an addition process on the preset variable flag. Subsequently, if the first page is returned from the second page, the second page enters the invisible state at this time, and the preset variable flag needs to be subjected to subtraction processing, and the first page enters the visible state, and the preset variable flag needs to be subjected to addition processing. It can be understood that each page in the application program can be processed by referring to the corresponding methods of the first page and the second page, and details are not described herein.
In the disclosed example, the value of the preset variable flag may be set to zero before the application program is started.
That is, when the application program is started but no page is opened, the value of the preset variable flag is zero, and with the start of the application program, the initial page or the main page is opened, at this time, the plus-one processing is started to be performed on the preset variable flag, and then the corresponding plus-one processing and minus-one processing are performed according to the page change.
In another possible implementation manner, when the application program is started and an initial page or a home page is opened, the preset variable flag is assigned to be one, and then corresponding plus and minus processes are executed according to page changes.
In practical applications, as the application program runs, the visible state of one page and the invisible state of another page usually appear in pairs, so as long as one page is in the visible state, the value of the preset variable flag will not be equal to zero, and as long as one page is in the visible state, it indicates that the application program is in the foreground state.
Therefore, in the embodiment of the present disclosure, step S102 includes:
when the value of the preset variable mark is non-zero, determining that the application program is in a foreground state;
and when the value of the preset variable mark is zero, determining that the application program is in a background state.
In general, it may be determined that the application program is in the foreground state directly when the value of the preset variable flag is one.
In a special case, for example, in a terminal having an application differentiation function, two or more identical applications may be executed at the same time, and at this time, it is necessary to determine that an application is in a foreground state when the value of the preset variable flag is any positive integer other than zero.
In practical application, the amount of the value of the preset variable flag may be determined according to other scenes capable of opening multiple pages to determine that the application program is in the foreground state.
The embodiment of the present disclosure further provides a feasible implementation manner, when a first page in an application program enters a visible state, after performing an addition process on a preset variable flag, recording a state of the first page.
And when a second page in the application program enters an invisible state, recording the state of the second page after executing subtraction processing on the preset variable mark.
That is, after the preset variable flag is subjected to plus-minus processing, the state of the corresponding page in the processing process needs to be recorded.
In practical application, when the application program has problems such as crash and flash back, or when the value of the preset variable mark has an error, the process of the occurrence of the problem or the error can be traced back according to the recorded page state, which is beneficial to the optimization of the application program. In other scenarios, the running process of the application program can be tracked according to the record.
The embodiment of the present disclosure further provides a feasible implementation manner, and after determining that the application program is in a foreground state, the implementation manner further includes the following steps: pages in the application that are in a visible state are determined. And then, corresponding processing can be executed on the page in the visible state, and the page displayed on the page can be known by the user due to the foreground state of the application program, so that the method and the device are particularly suitable for application scenes with strong interactivity.
In practical application, the above scheme can also be applied to the following functional scenarios:
(1) in an instant chat scene, if an application program is running in the foreground, the user is shown to be paying attention to chat contents in real time, and the user does not need to be reminded when receiving a new message, so that the user is prevented from being disturbed. If the application program is running in the background, the application program can remind or push the user in time when receiving a new message, so that the instantaneity of chatting is ensured.
(2) In a live video scene, some special effects may appear according to the operation of a user, if an application program is running in the foreground, the user can watch the special effects, and then the special effects can be displayed, so that the watching effect of the user is ensured. If the application program is running in the background, the special effects cannot be observed by the user, and the special effects are not displayed so as to reduce power consumption.
(3) In entertainment scenes such as games and the like, in order to ensure healthy entertainment experience, a user with overlong use time needs to be reminded, if the detected time reaches the preset time, the application program runs in the foreground, the reminder is sent immediately, and if the application program runs in the background, the reminder indicates that the user probably has been at rest, and the reminder does not need to be sent. In addition, in this scenario, it may also be detected whether the usage time is too long in combination with the above recording of the page state, for example, if the value of the preset variable flag is always non-zero within a predetermined time, or the number of times and time of occurrence of zero are small, it is determined that the user has too long the game time.
It will be appreciated by those skilled in the art that the foregoing scenarios are merely examples, and that suitable variations based on these examples are also applicable to the present disclosure and are intended to be included within the scope of the present disclosure.
According to the method for judging the foreground and background states of the application program, the value of the preset variable mark is obtained, and the preset variable mark is updated in real time based on the visible state and the invisible state of each page of the application program; according to the value of the preset variable mark, the foreground and background states of the application program can be quickly determined, so that different functions can be respectively realized aiming at the foreground state and the background state of the application program, and the performance of the application program is improved.

In an optional implementation manner, the determining module 202 is specifically configured to determine that the application program is in a foreground state when the value of the preset variable flag is non-zero; and when the value of the preset variable mark is zero, determining that the application program is in a background state.
