Detailed Description

The technical solutions in the present application will be described below with reference to the accompanying drawings.

In order to clearly describe the technical solutions of the embodiments of the present application, in the embodiments of the present application, the words "first", "second", etc. are used to distinguish the same item or similar items having substantially the same function and effect. It will be appreciated by those of skill in the art that the words "first," "second," and the like do not limit the amount and order of execution, and that the words "first," "second," and the like do not necessarily differ.

In this application, the terms "exemplary" or "such as" are used to mean serving as an example, instance, or illustration. Any embodiment or design described herein as "exemplary" or "for example" should not be construed as preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "such as" is intended to present related concepts in a concrete fashion.

Furthermore, "at least one" means one or more, and "a plurality" means two or more. "and/or", describes an association relationship of an association object, and indicates that there may be three relationships, for example, a and/or B, and may indicate: a alone, a and B together, and B alone, wherein a, B may be singular or plural. The character "/" generally indicates that the context-dependent object is an "or" relationship. "at least one of" or the like means any combination of these items, including any combination of single item(s) or plural items(s). For example, at least one (one) of a, b, and c may represent: a, b, or c, or a and b, or a and c, or b and c, or a, b and c, wherein a, b and c can be single or multiple.

For some operating systems that may be used in mobile phones, tablets, etc., the most recent task list may display a list of recently opened applications. The screen capture of the interface finally displayed by the application corresponding to the task and the information related to the task can be returned to the desktop management application (hereinafter referred to as desktop for short) through the latest task list, so that the desktop can display the application which is used recently by the user, and the user can conveniently switch the applications when operating multiple applications.

FIG. 1 is a flow diagram of a method 100 of calling up a list of recent tasks. The method 100 comprises the steps of:

s101, responding to the operation of a user, requesting to inquire a latest task list by a desktop;

s102, the component management service receives a query request;

s103, the component management service assembles task information and a task screenshot;

s104, the component management service returns a latest task list to the desktop, wherein the latest task list comprises the screenshot of the recently opened application.

Each time an application is started by the electronic device, a task (task) is imported into the stack of the latest task (task) of the system. When the user exits the application by operating a menu key (home key) or a return key, the application is typically switched from the foreground operation to the background operation. The component management service in the operating system intercepts the interface of the application before exiting, and records the current state information, including specific components. The component management service may save the screenshot under a certain path.

Illustratively, the user may call out the most recent task list by sliding the screen up, sliding the screen left (or right), or clicking the most recent task list key in the navigation key. In addition, the user can call out the latest task list through the function provided by the hover ball or the like. For example, the user may double click on the hover ball to call up the multi-tasking list.

FIG. 2 is an interface schematic of a recent task list. Illustratively, the user may call up the side application bar as shown in FIG. 2 by sliding the screen left at the right edge of the screen, with the recent task list displayed in the side application bar. The most recent task list in FIG. 2 shows a screenshot of the interface of the e-book APP and a screenshot of the interface of the music APP that the user has recently used. It should be understood that the screenshot of the application displayed in the most recent task list is the screenshot of the last displayed interface of the application, which refers to the interface displayed before the application exits from the foreground. When the screenshots of a plurality of applications need to be displayed, the screenshots of the plurality of applications are displayed according to the time sequence of the application exiting the foreground, and the sequencing of the application exiting the foreground is more advanced when the current system time is closer. After clicking the screenshot of an application, the electronic device switches the application from background operation to foreground operation, and displays the interface of the application.

FIG. 3 is an interface schematic of another recent task list. The user may call up the multi-tasking interface as shown in fig. 3 by sliding up from the bottom of the screen, which may also be referred to as a recent tasks interface, for displaying a recent tasks list where the user may view or clear the recent browsing records. Similar to the description for FIG. 2, shown in the most recent task list shown in FIG. 3 is a screenshot of an application, which the user can slide left and right to switch to display a screenshot of a different application.

Examples of common scenarios in which a user uses a recent task list are as follows:

scene 1: the user is getting on the car by using the car-taking APP, at this time, a chat message pops up, the user exits the car-taking APP and enters the chat APP by clicking the popped chat message, or the user returns to the desktop by a menu key (or home key), and then clicks an icon of the chat APP on the desktop to enter the chat APP. When a user enters the chat APP and wants to view the vehicle information in the taxi taking APP, the user can call out a latest task list, click a screenshot of the taxi taking APP in the latest task list, and then re-enter the taxi taking APP.

Scene 2: the user opens the electronic book APP and is watching the novel, and when watching, the user wants to listen to the music, and the user can call out the latest task list to switch between the music APP and the electronic book APP because the user may need to frequently switch to the music APP to perform operations such as music switching and song selection.

Scene 3: the user is sending an express delivery, the information of the sender is in the chat APP, and the user needs to frequently switch back and forth between the express delivery APP and the chat APP to input the information of the sender.

As can be seen from the above description of the scenario, when a user operates a plurality of applications at the same time, the user needs to frequently call up the latest task list to repeatedly switch between the plurality of applications, which is cumbersome to operate, and may cause an operation error when a screenshot of too many applications is displayed in the latest task list. In addition, when a user switches among a plurality of applications, the foreground and background states of the applications need to be frequently switched, and the driving of the lifecycle of the applications, the creation of windows and the restoration of interfaces are involved, which can cause excessive power consumption and poor performance experience. It should be understood that the above-mentioned latest task list displays all screenshot information of the application, and cannot provide other information and functions of the application for the user, for example, chat information of the chat APP; for another example, play information of music APP is provided, and functions of music switching, song selection and the like are performed; for another example, sender information in the express APP is provided, and so on.

In view of this, the embodiment of the application provides a method for displaying a recent task list and an electronic device, where the electronic device centralizes the cards of the recently used applications in one screen for displaying, and can provide more information of the applications in the recent task list, which is favorable for improving the interactive capability of the recent task list, improving the convenience of multi-application operation, and reducing the power consumption caused by switching the foreground and background states of the applications by the electronic device, and improving the usability of the electronic device.

The card of the application according to the embodiment of the present application is a User Interface (UI) element, which may be regarded as an information container, and includes information and operations of a certain content. Based on the content carried, the card design can adjust the card specification (size) for different devices and screens.

The styles (layouts) of cards may be different to support the content categories they contain. In general, the style of card may include one or more of the following components:

(1) Rich media: the card may contain thumbnails to display pictures, illustrations, avatars, logos (logos), icons or graphics.

(2) Title: the title text may contain the names or titles of photo albums or articles.

(3) Description of: text is supported, such as a text summary or a short description.

(4) Action button: the card may contain buttons for operation.

(5) Subheading: the subtitle text may contain detailed descriptions such as the signature of an article or a marked-up job.

Fig. 6 is a schematic flowchart of a method 600 for displaying a list of recent tasks according to an embodiment of the present application. The steps of method 600 may be performed by an electronic device, which may have a structure as shown in fig. 4 and/or fig. 5, but embodiments of the present application are not limited thereto. The method 600 includes the steps of:

S601, an operation for displaying a latest task list is received.

In some embodiments, this operation may be an operation to display a recent task list for a preset trigger.

S602, responding to the operation, displaying a latest task list, wherein the latest task list comprises cards of the first application, and the cards of the first application are used for dynamically displaying service contents of the first application.

Wherein the operation for displaying the latest task list may include a first operation of sliding left/right on the screen of the electronic device or a second operation of sliding up from the bottom of the screen of the electronic device. Further, the operation for displaying the latest task list may also be an operation of sliding obliquely upward from the lower left/lower right corner of the screen of the electronic apparatus, which is not limited in the embodiment of the present application.

The first application is the most recently running application, it being understood that each time an application is launched by the electronic device, a task is passed into the stack of the most recent tasks of the system. The application corresponding to the task recorded in the stack of the latest task is the application which is running recently. Applications that have been opened by a user in an electronic device may be referred to as recently run applications. For example, when the user opens a chat APP, the chat APP is the most recently running application; for example, when the user opens the music APP and switches the music APP from the pre-process to the background operation, the music APP is also the application that has been recently operated; for example, if the user opens the APP, but then the user manually ends the process of the APP, the APP is also the most recently running application.

In the embodiment of the application, after the electronic device receives the operation input by the user for displaying the latest task list, the electronic device can display the latest task list and dynamically display the card of the application which is recently run by the user. Dynamic display, among other things, may be understood as the presence of a portion of the application's card that may be updated or otherwise interacted with by the user. When the portion is available for the user to click to enter the display interface of the application, it may be to enter other interfaces of the application than the main interface.

The information provided by the application card can be dynamically updated in real time, or the functions provided by the application card can be used by a user, and the operation on a certain function can be completed on the application card. For example, for a translation card, a vocabulary translation function is provided, a user can input a vocabulary to be translated on the translation card for translation, the translation card displays a translation result, and the translation card is dynamically operable for the user and dynamically displays information.

Based on this, under a possible scene, when the user is using the electronic book APP to look at the novel, but in the looking process, the electronic device may call up the latest task list in response to the operation of the user, display the translation card, and the translation card may provide the function of vocabulary translation, so that the user does not need to switch from the electronic book APP to the dictionary APP to perform translation, but can quickly use the function provided by the application card in the latest task list, which is beneficial to improving the interaction performance of the latest task list and improving the convenience of the user to operate a plurality of applications.

In addition, repeated switching between different applications requires frequent switching of foreground and background states of the applications, involving lifecycle driving, window setup, and interface restoration, which can introduce additional power consumption. In the embodiment of the application, the frequent switching among different applications can be reduced, so that the power consumption caused by switching the foreground and background states of the applications is reduced, and the service performance of the electronic equipment is improved.

Interface diagrams of the recent task list according to embodiments of the present application are shown below in conjunction with fig. 7 to 11.

As an alternative embodiment, before displaying the most recent task list in response to the operation for displaying the most recent task list, the method 600 further includes: and displaying an application interface of the third application. In response to an operation for displaying the most recent task list, displaying the most recent task list includes: and responding to a first operation performed by a user on the application interface, and displaying a latest task list on the application interface. See in particular the interface shown in fig. 7 displaying the list of most recent tasks.

In this embodiment of the present application, the electronic device may call out a side application bar on an application interface that is currently being opened by a user, see interface B in fig. 7, where the side application bar may display cards of applications that have been recently used by the user, and the user may also adjust the display order of the cards of the applications in the side application bar. The user may select to operate the card of an application in the sidebar to implement a function of the application or to operate the card of an application to cause the application to open in a widget mode.

Fig. 7 is an interface schematic diagram of a recent task list according to an embodiment of the present application. As shown in the a interface in fig. 7, the scene in which the user is currently located is illustratively: the user calls the vehicle by using the taxi taking APP on the mobile phone, and waits for the arrival of the vehicle at the roadside. Since the vehicle has not arrived for a while, the user opens the e-book APP to see a foreign language novel and opens the music APP to listen to the music. The mid-way user may also open the dictionary APP to query for some words or chat with colleagues using the chat APP.

Under the scene, the user opens applications such as an electronic book APP, a taxi taking APP, a music APP, a dictionary APP, a chat APP and the like. After these applications have been opened, when the sub-device is currently resident on the reading novel interface of the electronic book APP, the third application may be the electronic book APP. Illustratively, the user may call up the most recent task list as shown in the B interface in fig. 7 by sliding from the right side of the screen to the left. As shown in the B interface in fig. 7, the electronic device displays the taxi taking card, the music card, the dictionary card and the chat card in the latest task list in a portrait display manner. It should be understood that the latest task list called up in this way may not display the card of the electronic book APP, so as to avoid that the interface and the card of the same application are displayed on the same screen, and avoid that the user clicks by mistake or clicks by invalidity. The first application in method 600 may be a taxi taking APP, a music APP, a dictionary APP, or a chat APP in an embodiment of the present application.

In other embodiments, when the third application is running in the foreground, the user brings up a recent task list by sliding from the right side of the screen to the left, which may display the cards of the third application.

As shown in the B interface in fig. 7, the electronic device displays the name of the application under the card of each application. It should be understood that the display positions of the names applied in fig. 7 are merely examples, and the directions of the card, such as the top, the side, etc., may also be displayed, which is not limited in the embodiment of the present application.

The taxi taking card is provided with the service content of the taxi taking APP, and the service content of the taxi taking APP can comprise vehicle information such as the distance and the remaining time of a vehicle. The service content of the taxi-taking APP can be dynamically updated on the taxi-taking card in real time, a user does not need to reenter the taxi-taking APP, and the service content of the taxi-taking APP can be checked on the interface of the current reading novel.

The service content of the music APP is displayed on the music card, and can comprise the name of the music currently being played, the switching music and the like, and can also comprise the name of the previous music and/or the name of the next music. The music card comprises a control for pausing/playing music, a control for switching the next piece of music and a control for switching the previous piece of music, so that a user can control the playing of music without entering a music APP.

The dictionary card displays the service content of the dictionary APP, which includes language selection, translation result, and the like. The dictionary card is provided with an input box, and a user can input a word to be translated in the input box for inquiring, so that the user can inquire the word without entering the dictionary APP.

The chat card displays the service content of the chat APP, wherein the service content of the chat APP comprises chat messages of friends with the chat, and the chat messages are displayed in a chat frame of the chat card. When the user reads the novel, the chat messages sent by the colleagues can be displayed in the chat frames on the chat cards, and the user can click the chat frames on the chat cards to input the messages and send the messages.

Illustratively, if the user desires to enter the taxi-taking APP from the B-interface in fig. 7, the user may click on the taxi-taking card to enter the taxi-taking APP.

Illustratively, if the user desires to enter the music APP from the B interface in fig. 7, the user may click on other areas of the music card than the actionable controls to enter the music APP. The way of entering the dictionary APP and chat APP is similar to the way of entering the music APP and will not be described here in detail.

In one possible implementation, the electronic device sorts and displays cards of the plurality of applications in the most recent task list in a time order in which the applications exit the foreground. The closer the time to exit the foreground is to the current system time, the earlier the display order of the application cards in the most recent task list.

For example, the chat APP exits the foreground at 8:00, the dictionary APP exits the foreground at 8:30, the music APP exits the foreground at 9:00, the driving APP exits the foreground at 9:30, the current electronic book APP is running in the foreground, and the electronic device displays a novel reading interface of the electronic book APP. When the electronic equipment responds to the operation of a user and calls out a latest task list from a novel reading interface of the electronic book APP, the taxi taking card, the music card, the dictionary card and the chat card are displayed in the latest task list according to the time sequence of the application exiting the foreground.

For example, if more applications are opened, too many cards cannot be displayed on the screen of the electronic device at the same time, some of the cards of the applications are hidden, and the user may slide the latest task list upward to display the hidden cards.

In one possible implementation, the user may desire to delete cards for certain applications because the cards may be wastefully consuming too much power to dynamically display the service content of the application. For example, after a user sits on a car to a destination, the user desires to delete a card of the car taken. In this case, the user may call up the latest task list, press the taxi-card to slide leftwards or rightwards, and then loosen his hand, so that the taxi-card may be deleted from the latest task list. Or, the user presses the taxi-taking card for a long time until the word or icon representing the deletion appears, and the user can select the word or icon representing the deletion to delete the taxi-taking card on the latest task list.

In fig. 7, a manner of calling up the latest task list by sliding from the right side of the screen to the left is shown, and in addition, the electronic device may be triggered to call up the latest task list by sliding from the lower left corner or the lower right corner of the screen obliquely to the upper side of the screen by the user, which is not limited in the embodiment of the present application.

In the interface B in fig. 7, the electronic device may display cards of multiple applications in the latest task list, so that the cards of the applications that have been used recently are concentrated in one screen to perform interaction, so that the user can quickly complete the interaction of multiple applications on a single interface, thereby improving convenience of performing multi-application operations on the electronic device such as a mobile phone, a tablet, and reducing cost of frequent application switching of the user. The card of the application can dynamically display the service content of the application and refresh the application information in time, so that the information transmission is more timely and effective, and the user can check the recent progress of the application currently in use in time.

An interface diagram for calling up the latest task list in the application interface is described above in connection with fig. 7, and in addition, the user may call up the latest task list on the desktop of the electronic device as shown in fig. 8.

FIG. 8 is an interface diagram of another recent task list provided by an embodiment of the present application. As shown in interface a in fig. 8, the electronic device displays one interface of the desktop application, and the user can slide in the screen from the screen edge to call up the latest task list as shown in interface B in fig. 8. For example, the user may slide into the screen from a preset position at the edge of the screen to call up the most recent task list.

As shown in the interface B in fig. 8, an electronic book card, a taxi taking card, a music card, a dictionary card, and a chat card are displayed in the latest task list, and the user can select one of the cards to enter an application interface corresponding to the card, so that the state of the application is switched from background operation to foreground operation. For example, the user clicks the electronic book APP, and in response to an operation of clicking the electronic book APP by the user, the electronic device displays a novel reading interface of the electronic book APP, where the novel reading interface is an interface displayed before the electronic book APP is switched from the foreground operation to the background operation.

As an alternative embodiment, before displaying the most recent task list in response to the operation for displaying the most recent task list, the method 600 further includes: and displaying an application interface of the third application. In response to an operation for displaying the most recent task list, displaying the most recent task list includes: and in response to a second operation performed by the user on the application interface, displaying a latest task list in the multi-task interface. See in particular the interface shown in fig. 9 displaying the list of most recent tasks.

FIG. 9 is an interface diagram of yet another recent task list provided by an embodiment of the present application. An example of a scenario in which the user is currently located may be referred to the description of fig. 7, and will not be described herein.

As shown in the interface a in fig. 9, the electronic device is currently staying in the interface for reading novels, and the user can call up the multi-tasking interface shown in the interface B in fig. 9 by performing an operation of sliding up from the bottom of the screen, the multi-tasking interface being for displaying applications that have been recently used by the user, i.e., for displaying a recent task list. As shown in interface B in fig. 9, electronic book cards, music cards, dictionary cards, chat cards, and taxi taking cards are displayed in the latest task list. The user can select to operate a card of an application in the multi-task interface to realize a function of the application, or operate the card of the application to enable the application to run in the foreground, and display the interface of the application in a full screen mode.

As shown in the interface B in fig. 9, the electronic book card, the music card, the dictionary card, the chat card, and the taxi taking card may be partially or completely stacked for display, and the current latest task list completely displays the electronic book card on which information of a novel that the user is currently reading is displayed. The icon and the name of the electronic book are displayed above the electronic book card. Other music cards, dictionary cards, chat cards, taxi cards are stacked and displayed below the electronic book card.

For example, when a user desires to control the playing of music, the user may slide the screen to the left so that the music card is displayed entirely on top of the other cards; or the user may click on the area where the music card is visible to cause the music card to be displayed intact on top of the other cards. When the music card is displayed completely on the uppermost side of other cards, the icon and name of the music APP can be displayed above the music card.

FIG. 10 is an interface schematic of yet another recent task list provided by embodiments of the present application. An example of a scenario in which the user is currently located may be referred to the description of fig. 7, and will not be described herein.

As shown in interface a in fig. 10, the electronic device is currently resident in the reading novel interface, and the user can call up the latest task list as shown in interface B in fig. 10 by sliding upward from the bottom of the screen. As shown in the interface B in fig. 10, electronic book cards, music cards, dictionary cards are displayed in the latest task list in a portrait display manner. The recent task list also includes chat cards, taxi taking cards, which are not displayed, and the user can display more application cards by sliding the screen up.

The foregoing shows a possible interface schematic for a list of recent tasks. The following describes a specific implementation manner of displaying the latest task list in the embodiment of the present application.

As an alternative embodiment, the electronic device displays the latest task list in response to an operation for displaying the latest task list, including: responsive to the operation, determining a state of a process of the first application; when the process of the first application runs in the background, determining to display the card of the first application in the latest task list; a recent task list including cards of the first application is displayed.

In the embodiment of the application, the electronic device may determine, according to the running condition of the process of the first application, that the card of the first application is displayed in the latest task list under the running condition of the application. In this way, the electronic device only displays the cards of the applications running in the background, which is beneficial to reducing the power consumption caused by displaying the cards of the excessive applications in the latest task list.

In some embodiments, the application running may include running in the foreground and running in the background, with the electronic device displaying an interface within the application while the application is running in the foreground. After the user switches the application from the foreground run to the background, if the user does not manually close the application or the system cleans up the background to close the application, the application will continue to run in the background.

Referring to the interface B in fig. 7, taking the first application as an example of the taxi taking APP, after receiving an operation for displaying the latest task list, the electronic device first detects the state of the progress of the taxi taking APP, and if the progress of the taxi taking APP runs in the background, the electronic device generates a taxi taking card and displays the taxi taking card in the latest task list. Other implementation logic for displaying music cards, dictionary cards, and chat cards in the recent task list is similar to that for displaying taxi cards, and will not be described again here.

It should be appreciated that typically an electronic device, after opening an application, runs in the background all the time the application's process is running, with enough system resources and without the user manually ending the application's process. However, because the system resources of the electronic device are limited, when the number of applications opened is too large, the system resources cannot meet the requirement of running too many applications in the background at the same time, so that the electronic device can select to end the process of some applications.

For example, if the electronic device detects that the runtime of a certain application is early and the user has not used the application for a long time, the electronic device may end the process of the application.

As an alternative embodiment, the electronic device displays the latest task list in response to an operation for displaying the latest task list, including: in response to the operation, determining whether the first application is configured to be displayed in the form of a card in the recent task list; determining to display a card of the first application in the recent task list when the first application is set to be displayed in the form of a card in the recent task list; a card recent task list including the first application is displayed.

In this embodiment of the present application, the electronic device considers whether the developer of the first application configures the first application to be displayed in the form of a card in the recent task list, and may also understand whether the developer of the first application configures the card that needs to display the first application in the recent task list.

Illustratively, the static configuration information of the first application configured by the developer of the first application includes a first field "isShowCrad", and when the value of the first field is true (true), it indicates that the first application is configured to be displayed in the form of a card in the latest task list.

As an alternative embodiment, the electronic device displays the latest task list in response to an operation for displaying the latest task list, including: responsive to the operation, determining a state of a process of the first application; when the process of the first application runs in the background, determining whether the first application is configured to be displayed in the form of a card in the latest task list; determining to display a card of the first application in the recent task list when the first application is set to be displayed in the form of a card in the recent task list; a recent task list including cards of the first application is displayed.

In the embodiment of the application, the electronic device can detect the state of the process of the first application and detect whether the first application is configured to be displayed in the form of a card in the latest task list. Under the condition that the two conditions are met, the electronic device can display the card of the first application on the latest task list. The state of the process of the first application includes the running state of the process of the first application in the background, which can also be understood as whether the process of the first application is still alive in the background. In this way, the electronic device only displays cards of applications where the process is still running in the background and configured to require the display of cards in the most recent task list, advantageously reducing power consumption by displaying cards of too many applications.

As an alternative embodiment, after determining to display the card of the first application in the recent task list, the electronic device obtains card information of the first application and generates the card of the first application based on the card information. Wherein the card information includes the specification of the card and the style of the card.

In the embodiment of the application, the card information is used for generating the card, and the specification of the card in the card information can also be described as the size of the card. Illustratively, the specifications of the card may include 1×2,2×1,2×2,2×4, and the like.

Alternatively, different card specifications may be configured on different modalities of electronic devices. For example, for a cell phone, the specification of the card may be configured to be 1×2; for tablet computers, the card specification may be configured to be 2 x 1.

The style of a card refers to the entire appearance of the card, and the style of the card is diverse. Illustratively, one card style includes rich media, titles, descriptions. Illustratively, another card style includes a title, a subtitle, an action button.

As an alternative embodiment, the latest task list further includes a screenshot of a second application, where the second application is a recently executed application, and the screenshot of the second application is used to display an interface of the second application.

In the embodiment of the application, the electronic device may display not only the card of the first application but also the screenshot of the second application in the latest task list. The power consumption of the electronic device for displaying the screenshot is small, so that the power consumption is saved. See in particular the interface for the most recent task list as shown in fig. 11.

FIG. 11 is an interface schematic of yet another recent task list provided by embodiments of the present application. For example, in one possible scenario example, a user waits on the road side for a vehicle to call through a taxi taking APP, during waiting the user opens the e-book APP to read novels, and opens the music APP to listen to music. Some time before this scenario, the user has also opened the talk APP.

Illustratively, the user may slide into the screen from a preset position at the edge of the screen to call up the most recent task list as shown in FIG. 11. The taxi taking card and the music card are displayed in the latest task list as shown in fig. 11, and a screenshot of the last display interface of the call APP is also displayed. The second application may include the call APP shown in fig. 11, and the first application may include the taxi taking APP and the music APP shown in fig. 11.

As shown in fig. 11, the electronic device may simultaneously display, on the latest task list, a card of an application whose process is still running in the background and a screenshot of an application whose process ends, so that a user may intuitively see which applications are running in the background and which applications have already ended, and thus, the user may further select to restart the application whose process has ended, or end the process of the application still running in the background, according to his own requirements.

Illustratively, the electronic device ends the chat APP process, but the user may be waiting for a message sent by the buddy. When the user calls the latest task list and discovers that the screenshot of the chat APP is displayed, the user can determine that the process of the chat APP is finished, so that the user can click the screenshot of the chat APP in the latest task list to restart the chat APP and enter the interface of the chat APP.

There are three ways to determine that a screenshot of a second application is displayed in the most recent task list:

in one possible implementation, the electronic device determines a state of a process of the second application in response to an operation for displaying the most recent task list; when the process of the second application has ended, it is determined that a screenshot of the second application is displayed in the most recent task list.

In another possible implementation, the electronic device determines whether to configure the second application to be displayed in the form of a card in response to an operation for displaying the most recent task list; when it is determined that the second application is not configured to be displayed in the form of a card, it is determined that a screenshot of the second application is displayed in the most recent task list.

Illustratively, the static configuration information of the second application configured by the developer of the second application includes a first field "isShowCrad", and when the value of the first field is false (false) or empty, it indicates that the second application is not configured to be displayed in the latest task list in the form of a card.

In yet another possible implementation, the electronic device determines a state of a process of the second application in response to an operation for displaying the most recent task list; when the process of the second application runs in the background, determining whether the second application is configured to be displayed in the form of a card; when it is determined that the second application is not configured to be displayed in the form of a card, it is determined that a screenshot of the second application is displayed in the most recent task list.

In this way, the electronic device detects the state of the process of the second application, i.e. whether the process of the second application is still running in the background, and whether the second application is configured to be displayed in the form of a card in the latest task list, which is advantageous in reducing excessive power consumption caused by excessive card display.

Fig. 12 is a schematic flowchart of another method 1200 for displaying a list of recent tasks according to an embodiment of the present application. The method 1200 may be interactively performed by internal functional modules of an electronic device, primarily involving a desktop, component management service, process management service, application package management service, card management service, as illustrated in fig. 5. The method 1200 includes S1201 to S1212, which specifically includes the following steps:

s1201, the desktop requests the latest task list from the component management service in response to the operation of the user.

The operation of triggering the display of the latest task list is described above and will not be described in detail here.

S1202, the component management service requests the process management service to query the state of the process of the target application based on the request.

In this step, the state of the process includes the running state of the process in the background. The target application includes an electronic device-initiated application recorded in a stack of the most recent tasks of the component management service. Each application has a corresponding name, and the component management service records the name of the target application.

The component management service may send the name of the target application to the process management service when requesting a query from the process management service as to whether the process of the target application survives.

S1203, the process management service determines the state of the process of the target application according to the name of the target application.

In this step, the process management service maintains running state information of the process, where the running state information of the process includes a name of an application that the process is still running in the background. After receiving the name of the target application, the process management service can query the running state information of the process for the name of the target application, if the name is queried, the process for the target application is still running in the background, and if the name is not queried, the process for the target application is finished.

S1204, the process management service returns the running condition of the process of the target application to the component management service.

When the process of the target application is still running, S1205 is executed. When the process of the target application has ended, S1211 is performed.

S1205, the component management service requests the configuration information of the target application from the application package management service under the condition that the process of the target application is still running in the background.

The configuration information of the target application includes a first field "isShowCrad", and when the value of the first field is true (true), it indicates that the target application is configured to be displayed in the form of a card in the latest task list. When the first field is false or empty, it indicates that the target application is not configured to be displayed in the form of a card in the recent task list.

Optionally, the configuration information of the target application further includes a second field, where the second field is used to indicate an identification of the card of the target application. Illustratively, a plurality of card specifications and card patterns are available for selection in the card management service, each card specification and card pattern combination having a corresponding card identification.

For example, the specification of the card corresponding to the identifier 1 is 1×2, and the style includes rich media and titles.

For example, the specification of the card corresponding to the identifier 2 is 2×1, and the style includes title, description and action button.

For example, the specification of the card corresponding to the logo 3 is 2×2, and the style is to include a subtitle and an icon.

S1206, the application package management service returns the configuration information of the target application to the component management service.

When the target application is configured to be displayed in the form of a card in the latest task list, S1207 is performed. When the target application is not configured to be displayed in the form of a card in the latest task list, S1211 is performed.

In S1207, the component management service requests card information of the target application, including the specification of the card and the style of the card, from the card management service in the case where it is determined that the target application is configured to be displayed in the form of the card in the latest task list.

Alternatively, the component management service may send the card identification of the target application to the card management service when requesting card information of the target application from the card management service.

S1208, the card management service returns the card information of the target application to the component management service.

Alternatively, if the card management service receives the identification of the card from the target application sent by the component management service, the card management service may return card information corresponding to the identification of the card of the target application to the component management service based on the identification of the card of the target application.

S1209, the component management service transmits the task information and the card information of the target application to the desktop.

Wherein the task information of the target application may include an icon and/or a name of the target application.

S1210, the desktop displays the cards of the target application on the latest task list.

In this step, the desktop generates a card of the target application based on the received card information, displays the card of the target application in the latest task list, and may display an icon and/or name of the target application above/below the card of the target application.

S1211, the component management service sends a screenshot of the last display interface of the target application to the desktop if it is determined that the process of the target application has ended or if it is determined that the target application is not configured to be displayed in the form of a card in the latest task list.

S1212, the desktop displays a screenshot of the last display interface of the target application on the most recent task list.

In the embodiment of the present application, S1205 and S1206 may also be executed before S1201, for example, after the electronic device starts the target application, the component management service requests the configuration information of the target application from the application package management service, and the application package management service returns the configuration information of the target application to the component management service based on the request.

It should be understood that the sequence numbers of the above processes do not mean the order of execution, and the execution order of the processes should be determined by the functions and internal logic of the processes, and should not constitute any limitation on the implementation process of the embodiments of the present application.
