Description

Technical Field

[0001] This application relates to the field of terminal technology, and in particular to a multi-task center display method and electronic device. Background Technology

[0002] The multitasking center function provided by electronic devices is used to manage the applications currently running on the electronic device. For example, a user can trigger the electronic device to display the multitasking center interface, and the electronic device can display an application snapshot of the currently running application on the multitasking center interface. A user can select an application on the multitasking center interface to trigger the application to run in the foreground on the electronic device, or a user can trigger the closure of an application on the multitasking center interface.

[0003] In some scenarios, when an electronic device displays a multitasking center interface, it needs to obtain application information of the currently running application, such as the application's name, icon, and screenshots. The electronic device displays the application information in the multitasking center without filtering or processing it, which may lead to abnormal display of the multitasking center, such as displaying a blank page, thus affecting the user experience. Summary of the Invention

[0004] This application provides a multitasking center display method and electronic device to improve the display effect of the multitasking center.

[0005] In a first aspect, this application provides a method for displaying a multitasking center. This method can be executed by an electronic device. In this method, in response to a user's first operation, the electronic device obtains application information of at least one application running on the electronic device. The first operation is used to trigger the electronic device to display the multitasking center. The application information of the at least one application includes the application information of the first application. The electronic device determines whether the application information of the first application meets preset display conditions. If the application information of the first application meets the preset display conditions, the electronic device displays the page corresponding to the first application in the multitasking center. Or, if the application information of the first application does not meet the preset display conditions, the electronic device does not display the page corresponding to the first application in the multitasking center.

[0006] In the above method, when an electronic device displays an application page in the multitasking center, it can determine whether to display the corresponding application page in the multitasking center based on preset display conditions. Only when the application information meets the preset display conditions will the corresponding application page be displayed in the multitasking center. This avoids display problems such as blank pages and missing key information that may occur when the electronic device directly displays the application page in the multitasking center based on the obtained application information.

[0007] In one possible design, the display conditions include at least one of the following: the application information of the first application includes the application name of the first application; the application information of the first application includes the application icon of the first application; the application information of the first application includes a screenshot of the application interface of the first application. With this design, when the electronic device determines that the application information does not include the application name, or does not include the application icon, or does not include a screenshot of the complete application interface, the electronic device will not display the application's page in the multitasking center. This ensures that the application pages displayed in the multitasking center all include complete information and avoid abnormal display problems such as blank pages.

[0008] In one possible design, the display conditions include at least one of the following: the privacy level of the first application meets a preset condition; the privacy level of the application interface of the first application meets a preset condition. Optionally, the preset condition can be a requirement for a privacy level, such as the preset condition allowing applications or application interfaces with low privacy levels to be displayed in the multitasking center. Through this design, for applications involving user privacy, the electronic device can only display the corresponding page of the application in the multitasking center when the privacy level of the application or application interface meets the preset condition, thereby preventing the leakage of user privacy information in the application interface screenshot when the corresponding page of the application is displayed in the multitasking center.

[0009] In one possible design, displaying the page corresponding to the first application in the multitasking center includes: blurring a screenshot of the first application's interface based on the privacy level of the first application or the privacy level of the application's interface; and displaying the page corresponding to the first application in the multitasking center, wherein the page includes the blurred screenshot of the first application's interface. This design allows electronic devices to further ensure user privacy and security when displaying pages of applications involving user privacy in the multitasking center, by blurring the application's interface screenshot before display.

[0010] In one possible design, displaying the page corresponding to the first application in the multitasking center includes: when the application information of the at least one application includes multiple application information corresponding to multiple application interfaces of the first application, selecting at least one application information from the multiple application information, and displaying the page corresponding to the at least one application interface of the first application in the multitasking center based on the at least one application information. With this design, when the electronic device obtains multiple application information of the first application, it can select at least one application information from the multiple application information and display the page corresponding to at least one application information in the multitasking center, thereby avoiding displaying too many pages of the same application in the multitasking center and affecting the display effect.

[0011] In one possible design, the at least one application interface includes the application interface most recently used by the user among the plurality of application interfaces, and / or the application interface most frequently used by the user among the plurality of application interfaces.

[0012] In one possible design, when an electronic device selects at least two application information items from multiple application information items in a first application, the application interface types of at least two application interfaces corresponding to the at least two application information items are different. This design avoids displaying pages corresponding to duplicate application interface types in the multitasking center, preventing the display of too many similar pages from affecting the display effect.

[0013] In one possible design, before determining whether the first application information of the first application meets the preset display conditions, the method further includes: determining the privacy level of the first application based on the stored correspondence between applications and privacy levels, or determining the privacy level of the application interface of the first application based on the stored correspondence between application interfaces and privacy levels; or determining the privacy level of the first application based on the first field in the first application information of the first application, or determining the privacy level of the application interface of the first application based on the first field.

[0014] In one possible design, the preset display conditions are either system-preconfigured or user-defined. This design allows the electronic device to provide system-preconfigured display conditions, or allows users to customize display conditions to meet their individual needs.

[0015] Secondly, this application provides an electronic device comprising multiple functional modules; the multiple functional modules interact to implement the methods performed by the electronic device in any of the above aspects and their respective embodiments. The multiple functional modules can be implemented based on software, hardware, or a combination of software and hardware, and the multiple functional modules can be arbitrarily combined or divided based on specific implementations.

[0016] Thirdly, this application provides an electronic device including at least one processor and at least one memory, wherein the at least one memory stores computer program instructions, and when the electronic device is running, the at least one processor executes any of the above aspects and the methods executed by the electronic device in its various embodiments.

[0017] Fourthly, this application also provides a computer program product containing instructions that, when the computer program product is run on a computer, cause the computer to perform the method executed by the electronic device in any of the above aspects and embodiments.

[0018] Fifthly, this application also provides a computer-readable storage medium storing a computer program that, when executed by a computer, causes the computer to perform the method executed by the electronic device in any of the above aspects and embodiments.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the embodiments of this application will be further described in detail below with reference to the accompanying drawings. In the description of the embodiments of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0030] It should be understood that in the embodiments of this application, "at least one" means one or more, and "more than one" means two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone, where A and B can be singular or plural. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship. "At least one of the following" or similar expressions refer to any combination of these items, including any combination of single or plural items. For example, at least one of a, b, or c can represent: a, b, c, a and b, a and c, b and c, or a, b, and c, where a, b, and c can be single or multiple.

[0031] The multitasking center function provided by electronic devices is used to manage the applications currently running on the electronic device, such as... Figure 1 This is a schematic diagram of the display interface of the multi-task center provided in an embodiment of this application. (Refer to...) Figure 1 The multitasking center displays a page showing currently running applications on an electronic device. This page includes the application's name, icon, and a screenshot of the application interface. Users can select an application in the multitasking center to run it in the foreground, or they can close an application by swiping up on the application page.

[0032] In some scenarios, when an electronic device displays a multitasking center, it needs to obtain application information of the currently running application, such as the application's name, icon, and screenshots. The device then displays the application information in the multitasking center without filtering or processing it. If the application interface is a transitional screen between different interfaces, or if there is an underlying error when the device obtains application information, such as an interrupted interface transmission or other data transmission anomalies, the obtained application information may be incomplete. Similarly, incomplete application interface parameter configurations can also lead to missing application information, such as missing application names, icons, or screenshots. In these cases, when the device displays the application page in the multitasking center based on this information, incomplete display issues may occur, such as displaying a blank page, negatively impacting the user experience.

[0033] In other scenarios, the custom launch methods of some applications installed on electronic devices may result in multiple task stacks corresponding to the application during its operation. When the electronic device obtains the application information of the application, it may obtain information from multiple application interfaces. Among these multiple application interfaces, there may be duplicate interfaces. When the electronic device displays the application's page in the multitasking center, it may display two identical pages, which affects the user experience.

[0034] For example, Figure 2 This is a schematic diagram illustrating an abnormal display of a multitasking center on an electronic device. (Reference) Figure 2 In clause (a), when the application information obtained by the electronic device does not include the application name, the application name cannot be displayed on the page shown by the electronic device; see reference. Figure 2 In (b) of this clause, when the application information obtained by the electronic device does not include screenshots of the application interface, the electronic device displays a blank page in the multitasking center; see reference. Figure 2 In (c), the electronic device obtains information about multiple application interfaces of the social application from multiple task stack interfaces. Among the multiple application interfaces, there are two duplicate application interfaces. The electronic device displays the two duplicate pages corresponding to the social application in the multi-task center.

[0035] To address the above problems, this application provides a multi-task center display method, which can be executed by an electronic device. In this method, in response to a user's first operation, application information of at least one application running on the electronic device is obtained. The first operation triggers the electronic device to display a multi-task center interface. The application information of the at least one application includes the application information of a first application. The electronic device determines whether the application information of the first application meets preset display conditions. If the application information of the first application meets the preset display conditions, the electronic device displays the page corresponding to the first application in the multi-task center; or if the application information of the first application does not meet the preset display conditions, the electronic device does not display the page corresponding to the first application in the multi-task center. Through this solution, when the electronic device displays an application page in the multi-task center, it can filter the obtained application information according to preset display conditions to determine whether to display the corresponding page of the application in the multi-task center, avoiding display problems such as blank pages and missing key information that may occur when the electronic device directly displays the application page in the multi-task center based on the obtained application information.

Different antennas can also be multiplexed to improve antenna utilization. For example, antenna 1 can be multiplexed as a diversity antenna for a wireless local area network. In some other embodiments, the antennas can be used in conjunction with tuning switches.

The wireless communication module 160 can also receive signals to be transmitted from processor 110, perform frequency modulation and amplification, and convert them into electromagnetic waves for radiation via antenna 2.

[0044] In some embodiments, antenna 1 of electronic device 100 is coupled to mobile communication module 150, and antenna 2 is coupled to wireless communication module 160, enabling electronic device 100 to communicate with networks and other devices via wireless communication technology.

[0046] Camera 193 is used to capture still images or videos. An object is projected onto a photosensitive element by generating an optical image through the lens. The photosensitive element can be a charge-coupled device (CCD) or a complementary metal-oxide-semiconductor (CMOS) phototransistor. The photosensitive element converts the light signal into an electrical signal, which is then passed to an ISP for conversion into a digital image signal. The ISP outputs the digital image signal to a DSP for processing. The DSP converts the digital image signal into image signals in standard RGB, YUV, or other formats. In some embodiments, the electronic device 100 may include one or N cameras 193, where N is a positive integer greater than 1.

[0054] Understandable, Figure 3The components shown do not constitute a specific limitation on the electronic device 100. The electronic device may also include more or fewer components than shown, or combine some components, or separate some components, or have different component arrangements. Furthermore, Figure 3 The combination / connection relationships between the components can also be adjusted and modified.

[0055] Figure 4 This is a software structure block diagram of an electronic device provided in an embodiment of this application. For example... Figure 4 As shown, the software architecture of an electronic device can be a layered architecture. For example, the software can be divided into several layers, each with a clear role and division of labor. Layers communicate with each other through software interfaces. In some embodiments, the operating system is divided into four layers, from top to bottom: the application layer, the application framework layer (framework, FWK), the runtime and system libraries, and the kernel layer.

[0056] The application layer can include a series of application packages. For example... Figure 4 As shown, the application layer can include the camera, settings, skin modules, user interface (UI), and third-party applications. Third-party applications can include gallery, calendar, call, map, navigation, WLAN, Bluetooth, music, video, SMS, and a multitasking center. The multitasking center can be a system application for the electronic device, used to display information about the applications currently running on the device.

[0057] The application framework layer provides an application programming interface (API) and programming framework for applications in the application layer. The application framework layer can include some predefined functions. For example... Figure 4 As shown, the application framework layer may include a window manager, content provider, view system, phone manager, resource manager, notification manager, and capability manager service (AMS).

[0058] The window manager is used to manage windowed applications. It can obtain the screen size, determine if a status bar is present, lock the screen, and capture screenshots. The content provider stores and retrieves data, making this data accessible to applications. This data may include videos, images, audio, made and received phone calls, browsing history and bookmarks, phone books, etc.

[0059] A view system includes visual controls, such as controls for displaying text and controls for displaying images. View systems can be used to build applications. A display interface can consist of one or more views. For example, a display interface including a text notification icon could include views for displaying text and views for displaying images.

[0060] A phone manager is used to provide communication functions for electronic devices. For example, it manages call status (including connection and disconnection).

[0061] The file explorer provides applications with various resources, such as localized strings, icons, images, layout files, video files, and more.

[0062] The notification manager allows applications to display notifications in the status bar. These notifications can be used to deliver informational messages and can disappear automatically after a short pause, requiring no user interaction. For example, the notification manager can be used to notify users of completed downloads or message alerts. The notification manager can also display notifications as icons or scrolling text in the top status bar, such as notifications from background applications, or as dialog boxes on the screen. Examples include displaying text messages in the status bar, emitting sounds, vibrating electronic devices, and flashing indicator lights.

[0063] In this embodiment of the application, AMS can be used to manage tasks running in the application, such as obtaining application information from the task stack currently running in the application and sending the obtained application information to the multi-task center so that the multi-task center can display the page corresponding to the application based on the application information.

[0064] The runtime includes the core libraries and the virtual machine. The runtime is responsible for the scheduling and management of the operating system.

[0065] The core library consists of two parts: one part contains the functionalities that the Java language needs to call, and the other part contains the core libraries of the operating system. The application layer and application framework layer run in the virtual machine. The virtual machine executes the Java files of the application layer and application framework layer as binary files. The virtual machine is used to perform functions such as object lifecycle management, stack management, thread management, security and exception management, and garbage collection.

[0066] System libraries can include multiple functional modules. For example: surface manager, media libraries, 3D graphics processing libraries (e.g., OpenGL ES), 2D graphics engines (e.g., SGL), image processing libraries, etc.

[0067] The Surface Manager is used to manage the display subsystem and provides the blending of 2D and 3D layers for multiple applications.

[0068] The media library supports playback and recording of various common audio and video formats, as well as still image files. It supports multiple audio and video encoding formats, such as MPEG4, H.264, MP3, AAC, AMR, JPG, and PNG.

[0069] The 3D graphics processing library is used to implement 3D graphics drawing, image rendering, compositing, and layer processing.

[0070] A 2D graphics engine is a graphics engine for 2D drawing.

[0071] The kernel layer is the layer between hardware and software. The kernel layer contains at least the display driver, camera driver, audio driver, and sensor driver.

[0072] The hardware layer can include various types of sensors, such as accelerometers, gyroscopes, and touch sensors.

[0073] It should be noted that, Figure 3 and Figure 4 The structure shown is merely an example of an electronic device provided in this application embodiment and is not intended to limit the electronic device provided in this application embodiment in any way. In specific implementations, the electronic device may have a more advanced design than... Figure 3 or Figure 4 The structure shown may contain more or fewer devices or modules.

[0074] The multi-task center display method provided in the embodiments of this application is described below.

[0075] In this embodiment, in response to a user's first operation, the electronic device obtains application information of at least one currently running application. The first operation is used to activate a multitasking center, i.e., to trigger the electronic device to display the multitasking center interface. After detecting the first operation, the electronic device can determine at least one currently running application. This application includes both foreground and background applications. The electronic device can obtain application information for at least one application through the interfaces provided by each application. The application information for each application may include the application name, application icon, and a screenshot of the application interface.

[0076] Before displaying an application's page in the multitasking center interface, the electronic device can determine at least one target application that can be displayed in the multitasking center from at least one application, based on preset display conditions and at least one piece of application information obtained. Optionally, the preset display conditions can be system-configured or user-defined conditions. These preset conditions can be used to filter applications displayed in the multitasking center. For example, preset display conditions may include at least one of the following: the application information includes the application name; the application information includes the application icon; the application information includes a screenshot of the complete application interface; the application's privacy level meets preset conditions; the application's interface privacy level meets preset conditions, etc. After obtaining the application information of at least one application, the electronic device can compare the application information of at least one application with the preset display conditions, and then filter at least one target application that can be displayed in the multitasking center from at least one application. Taking the application information of at least one application obtained by the electronic device, including the application information of the first application, as an example, the electronic device can determine whether the application information of the first application meets the preset display conditions. When the application information of the first application meets the preset display conditions, the electronic device displays the page corresponding to the first application in the multi-task center; when the application information of the first application does not meet the preset display conditions, the electronic device does not display the page corresponding to the first application in the multi-task center.

[0077] After identifying at least one target application that can be displayed in the multitasking center interface, the electronic device displays a page corresponding to at least one target application in the multitasking center based on the application information of the at least one target application. Each page corresponding to a target application may include the application name, application icon, and a screenshot of the application interface. For example, refer to... Figure 1 Taking the display of the gallery app's corresponding page and the social app's corresponding page in the multitasking center interface as an example, users can swipe left and right in the multitasking center interface to view the pages corresponding to different apps.

[0078] In some examples of this application, the preset display conditions include: the application information includes the application name, the application information includes the application icon, and the application information includes a screenshot of the complete application interface. After the electronic device obtains the application information, it can determine whether the application information includes the application name, application icon, and a screenshot of the complete application interface based on different fields in the application information. A complete application interface refers to an application interface that is not a transitional or blank interface. When the electronic device determines that the application information does not include the application name, application icon, or a screenshot of the complete application interface, the electronic device will not display the application's page in the multitasking center. This ensures that the pages corresponding to the applications displayed in the multitasking center all include complete information and avoid abnormal display issues such as blank pages.

[0079] In some scenarios, when an application on an electronic device is running, taking the first application as an example, if a user opens multiple application interfaces of the first application, the first application may have multiple task stacks. Therefore, when the electronic device obtains application information for the first application, it may obtain multiple application information entries, each corresponding to an application interface. When the electronic device displays the page corresponding to the first application in the multi-task center, it can select at least one application information entry from the multiple application information entries for the first application and display at least one page corresponding to the first application in the multi-task center based on the selected entry.

[0080] In one optional implementation, when the electronic device selects at least one application from multiple application information of a first application, it can filter duplicate application interfaces among the multiple application interfaces corresponding to the acquired application information. For example, the electronic device can determine whether multiple application interfaces are the same based on the application interface path and name in the acquired application information, and filter the identical application interfaces among the multiple application interfaces, displaying the page corresponding to any one of the duplicate application interfaces in the multi-task center interface. For instance, when the electronic device supports dual-app functionality, taking a social application as an example, if a user clicks to run the social application twice on the electronic device, and each time the user selects to display the same chat interface, the electronic device will acquire two application information corresponding to two identical chat interfaces when acquiring the application information of the social application. The electronic device can filter the multiple application information corresponding to multiple duplicate application interfaces of the same application, retaining only one application information among the multiple application information corresponding to multiple duplicate application interfaces. In this way, when the electronic device acquires application information corresponding to multiple identical application interfaces, it can filter the multiple identical application interfaces, retaining only the page corresponding to one application interface in the multi-task center, ensuring the cleanliness of the multi-task center interface.

[0081] Optionally, when the electronic device selects at least one application information from multiple application information of the first application and displays at least one page corresponding to the first application in the multi-task center based on the at least one application information, the number of pages corresponding to the same application that the multi-task center can display can be a system-preconfigured or user-defined value. Optionally, the at least one application interface corresponding to the at least one application information selected by the electronic device may include the application interface most recently used by the user among multiple application interfaces, and / or the application interface most frequently used by the user.

[0082] In some examples, when an electronic device selects at least two application information items from multiple application information items of a first application, the at least two application interfaces corresponding to these at least two application information items can be application interfaces of different types. For example, when an electronic device obtains multiple application information items of a social application, including application information 1, application information 2, and application information 3, where application information 1 corresponds to chat interface 1, application information 2 corresponds to chat interface 2, and application information 3 corresponds to a shopping interface, the electronic device can select application information 3 and application information 1 from the multiple application information items, or the electronic device can select application information 3 and application information 2, thereby avoiding the display of pages corresponding to duplicate types of application interfaces in the multitasking center and preventing the display effect from being affected by displaying too many similar pages in the multitasking center. Optionally, when an electronic device obtains multiple application interfaces of the same type among multiple application interfaces of the same application, the at least one application interface selected by the electronic device can include the application interface with the highest user frequency among the multiple application interfaces of the same type, the application interface recently used by the user, or the user's preset user interface. For example, multiple chat interfaces of a social application can be set to be displayed, while only one shopping interface of the social application can be displayed. For example, if an electronic device obtains application information from multiple chat interfaces of a social application, it can select the chat interface that the user has recently used from among the multiple chat interfaces.

[0083] For example, Figure 5 This is a schematic diagram of a multi-task center provided in an embodiment of this application, with reference to... Figure 5 When an electronic device obtains multiple application information from a social application, each application information corresponds to an application interface. For example, if the electronic device obtains application information corresponding to chat interface 1, chat interface 2, and shopping interface 1, where shopping interface 1 is the user's most recently used application interface, chat interface 1 and chat interface 2 are application interfaces of the same type, and the user's most recently used application interface among chat interface 1 and chat interface 2 is chat interface 1, then refer to... Figure 5 The electronic device can select application information from shopping interface 1 and application information from chat interface 1, and display the corresponding pages of shopping interface 1 and chat interface 1 in the multi-task center.

[0084] In this way, when an electronic device obtains application information corresponding to multiple different application interfaces of the same application, the electronic device can filter out at least one application interface from the multiple application interfaces and display the page corresponding to the at least one application interface in the multi-task center interface, thereby preventing too many interfaces of the same application from being displayed in the multi-task center interface, which would affect the user experience.

[0085] In some embodiments of this application, some applications in the electronic device may involve user privacy information. The preset display conditions may further include ensuring that the application privacy level meets a preset condition. For example, the application privacy level may include high privacy level, medium privacy level, and low privacy level. For example, ensuring the application privacy level meets a preset condition may mean that the application privacy level is not higher than the low privacy level. Therefore, after the electronic device obtains the application information of a first application, if the privacy level of the first application is high or medium, the electronic device will not display the page corresponding to the first application in the multi-task center. If the privacy level of the first application is low, the electronic device can display the page corresponding to the first application in the multi-task center. Optionally, when the electronic device obtains multiple application information of the first application, if the privacy level of the first application does not meet the preset condition, then the multiple application interfaces corresponding to the multiple application information will not be displayed in the multi-task center.

[0086] In some examples, when an electronic device displays a page corresponding to a first application containing privacy information in a multitasking center, the device can blur the screenshot of the first application's interface. For instance, the electronic device can blur the screenshot based on the privacy level of the first application and display the corresponding page in the multitasking center, including the blurred screenshot. Optionally, when the first application has a high privacy level, the electronic device can perform high-level blurring on the screenshot; when the first application has a medium privacy level, the electronic device can perform medium-level blurring; and when the first application has a low privacy level, the electronic device can perform low-level blurring.

[0087] Optionally, the electronic device may store the privacy levels of multiple applications. When the electronic device obtains the application information of the first application, it can determine the privacy level of the first application based on the stored privacy levels of the multiple applications. Alternatively, the application information of the first application may include a first field, which is used to indicate the privacy level of the first application. The electronic device can then determine the privacy level of the first application based on the first field.

[0088] In some embodiments of this application, the preset display conditions may further include the application interface's privacy level meeting preset conditions. The application interface's privacy level may include, for example, a high privacy level, a medium privacy level, and a low privacy level. Meeting the preset conditions for the application interface's privacy level may be that the application's privacy level is not higher than the low privacy level. After obtaining the application information of the first application, the electronic device can obtain the privacy level of the application interface corresponding to the application information of the first application. If the privacy level of the application interface is a high privacy level or a medium privacy level, the electronic device will not display the page corresponding to the application interface in the multitasking center. If the privacy level of the application interface is a low privacy level, the electronic device can display the page corresponding to the application interface in the multitasking center.

[0089] In some examples, when an electronic device displays the page corresponding to the application interface of a first application containing privacy information in a multitasking center, the electronic device can also blur the screenshot of the application interface of the first application. For example, the electronic device can blur the screenshot of the application interface of the first application based on the privacy level of the application interface of the first application, and display the page corresponding to the application interface of the first application in the multitasking center. The page corresponding to the application interface of the first application includes the blurred screenshot of the application interface of the first application.

[0090] In some embodiments of this application, applications in an electronic device can be pre-configured with different privacy levels for their interfaces, or users can set privacy levels for application interfaces involving user privacy. For ordinary social applications, the privacy level is medium, but the privacy level of payment and billing interfaces in a social application can be set to high, and the chat interface in a social application can be set to low. Different privacy levels correspond to different degrees of blurring; for example, a high privacy level application interface corresponds to high blurring, and a low privacy level application interface corresponds to light blurring.

[0091] In one optional implementation, the electronic device can store a set of application interfaces corresponding to different privacy levels according to the privacy level of the application interface. When the electronic device displays the page corresponding to the first application in the multi-task center interface according to the application information of the first application, the electronic device can determine whether the application interface belongs to the set of application interfaces corresponding to a certain privacy level according to the identifier of the application interface in the application information. When the application interface belongs to the set of application interfaces corresponding to a certain privacy level, the electronic device can perform blurring processing corresponding to the privacy level on the screenshot of the application interface.

[0092] In another optional implementation, the application information of the first application obtained by the electronic device may also include a first field. The first field may be used to indicate the privacy level of the application interface, or the first field may be used to indicate the degree of blurring of the screenshot of the application interface. Then, after obtaining the application information of the first application, when the electronic device displays the page corresponding to the first application in the multi-task center interface according to the application information of the first application, it may blur the screenshot of the application interface according to the first field in the application information.

[0093] For example, Figure 6 This is a schematic diagram of a multi-task center interface provided in an embodiment of this application. (Reference) Figure 6 Taking the example of an electronic device obtaining application information corresponding to multiple application interfaces of a shopping application, when the electronic device obtains application information of the payment interface and the product interface of the shopping application, and displays the page corresponding to the payment interface and the page corresponding to the product interface in the multi-task center interface, it can determine whether to blur the screenshot of the application interface and the degree of blurring based on the privacy level of the application interface. For example, if the privacy level of the payment interface is high privacy level and the product interface is not a privacy interface, the electronic device can perform high blurring on the screenshot of the payment interface, and then the electronic device can display the page corresponding to the payment interface and the page corresponding to the product interface after high blurring in the multi-task center interface.

[0094] Based on the above embodiments, Figure 7 This is a schematic diagram of the structure of an electronic device provided in an embodiment of this application, with reference to... Figure 7 In this embodiment of the application, the electronic device may include multiple applications, an ability manager service (AMS), and a multi-task center. The multiple applications of the electronic device can provide various services to the user. Figure 7 The example shown is the first application in an electronic device; AMS can be used to manage the tasks running in the application, and the multi-task center can be used for the system application of the electronic device to display information about the application currently running on the electronic device.

[0095] In some examples, the first application may be included among the multiple applications on an electronic device. For instance, if the electronic device is running the first application, and the first application is running multiple tasks, then the first application has multiple task stacks, such as... Figure 7The first application shown includes task stack 1, task stack 2, etc., with each task stack corresponding to an application interface. The Application Management System (AMS) can manage the tasks of applications running on the electronic device. For example, the AMS can obtain multiple application information corresponding to multiple task stacks from the first application. Each piece of application information indicates information about an application interface, such as the application name, application icon, and screenshot of the application interface. The AMS sends the obtained application information of the first application to the multi-task center. The multi-task center can determine whether to display the page corresponding to the application in the multi-task center based on the received application information. Furthermore, the multi-task center can select at least one piece of application information from multiple pieces of application information and display the page corresponding to the first application in the multi-task center based on the selected at least one piece of application information.

[0096] It should be noted that, Figure 7 The illustrated embodiment is merely an example of an electronic device and is not intended to limit its functionality. In practice, the electronic device may have other structures, such as including other functional modules. Figure 7 The functions of the illustrated modules can also be performed by other functional modules in the electronic device, and this application embodiment does not limit this. In addition, multiple functional modules in the electronic device can be implemented based on software, hardware, or a combination of software and hardware, and multiple functional modules can be arbitrarily combined or divided based on specific implementations.
