As shown in fig. 4, in the embodiment of the present application, the application framework layer includes a manager (Managers), a Content Provider (Content Provider), a View System (View System), and the like, where the manager includes at least one of the following modules: an Activity Manager (Activity Manager) is used for interacting with all activities running in the system; the Location Manager (Location Manager) is used for providing the system service or application with the access of the system Location service; a Package Manager (Package Manager) for retrieving various information related to an application Package currently installed on the device; a Notification Manager (Notification Manager) for controlling display and clearing of Notification messages; a Window Manager (Window Manager) is used to manage the icons, windows, toolbars, wallpapers, and desktop components on a user interface.

In some embodiments, the activity manager is to: managing the life cycle of each application program and the general navigation backspacing function, such as controlling the exit of the application program (including switching the user interface currently displayed in the display window to the system desktop), opening, backing (including switching the user interface currently displayed in the display window to the previous user interface of the user interface currently displayed), and the like.

In some embodiments, the window manager is used to manage all window processes, such as obtaining display size, determining if there is a status bar, locking the screen, intercepting the screen, controlling display window changes (e.g., zooming out, dithering, distorting, etc.) and the like.

In some embodiments, the system runtime layer provides support for the upper layer, i.e., the framework layer, and when the framework layer is used, the android operating system runs the C/C + + library included in the system runtime layer to implement the functions to be implemented by the framework layer.

In some embodiments, the kernel layer is a layer between hardware and software. As shown in fig. 4, the core layer includes at least one of the following drivers: audio drive, display drive, bluetooth drive, camera drive, WIFI drive, USB drive, HDMI drive, sensor drive (such as fingerprint sensor, temperature sensor, touch sensor, pressure sensor, etc.), and so on.

In some embodiments, the kernel layer further comprises a power driver module for power management.

In some embodiments, software programs and/or modules corresponding to the software architecture of fig. 4 are stored in the first memory or the second memory shown in fig. 2 or 3.

In some embodiments, taking the magic mirror application (photographing application) as an example, when the remote control receiving device receives a remote control input operation, a corresponding hardware interrupt is sent to the kernel layer. The kernel layer processes the input operation into an original input event (including information such as a value of the input operation, a timestamp of the input operation, etc.). The raw input events are stored at the kernel layer. The application program framework layer obtains an original input event from the kernel layer, identifies a control corresponding to the input event according to the current position of the focus and uses the input operation as a confirmation operation, the control corresponding to the confirmation operation is a control of a magic mirror application icon, the magic mirror application calls an interface of the application framework layer to start the magic mirror application, and then the kernel layer is called to start a camera driver, so that a static image or a video is captured through the camera.

In some embodiments, for a display device with a touch function, taking a split screen operation as an example, the display device receives an input operation (such as a split screen operation) applied to a display by a user, and the kernel layer may generate a corresponding input event according to the input operation and report the event to the application framework layer. The window mode (such as multi-window mode) corresponding to the input operation, the position and size of the window and the like are set by an activity manager of the application framework layer. And the window management of the application program framework layer draws a window according to the setting of the activity manager, then sends the drawn window data to the display driver of the kernel layer, and the display driver displays the corresponding application interface in different display areas of the display.

In some embodiments, as shown in fig. 5, the application layer containing at least one application may display a corresponding icon control in the display, such as: a live television application icon control, a Video On Demand (VOD) application icon control, a media center application icon control, an application center icon control, a game application icon control, and the like.

In some embodiments, the live television application may provide live television via different signal sources. For example, a live television application may provide television signals using input from cable television, radio broadcasts, satellite services, or other types of live television services. And, the live television application may display video of the live television signal on the display device 200.

In some embodiments, a video-on-demand application may provide video from different storage sources. Unlike live television applications, video on demand provides a video display from some storage source. For example, the video on demand may come from a server side of the cloud storage, from a local hard disk storage containing stored video programs.

In some embodiments, the media center application may provide various applications for multimedia content playback. For example, a media center, which may be other than live television or video on demand, may provide services that a user may access to various images or audio through a media center application.

In some embodiments, an application center may provide storage for various applications. The application may be a game, an application, or some other application associated with a computer system or other device that may be run on the smart television. The application center may obtain these applications from different sources, store them in local storage, and then be operable on the display device 200.

The above embodiments show a display device, in practical applications, the display device includes but is not limited to a smart phone, a tablet computer, a notebook computer, a television, and the like, an application program related to a required service/function is installed in the display device, and a service management program is added, and the service management program is embodied in a software layer and is a service architecture/specification of unified background service process management. The controller 250 may control the start execution or stop operation of the service manager. The background service management method in the present application is mainly that the controller 250 starts the service management program and the service management program executes the service management program.

As shown in the background service management architecture of fig. 6, for convenience of illustration, the service management program in fig. 6 is executed by a virtual service management module 500, and the service management module 500 is not characterized as a hardware structure of the service management program. The service management module 500 is connected to a plurality of event detection modules 501, N event detection modules are N in fig. 6, N is an integer greater than 0, the event detection modules 501 are installed in a manner of adapting to an application program, when the application program is newly installed, corresponding event detection modules can be added to connect to the service management module 500, and the event detection modules 501 work in parallel. The service management module 500 may passively receive event information sent by each event detection module, or may query the event detection module at regular intervals for whether an event arrives or not in a regular query manner.

In some embodiments, as shown in fig. 7, the controller 250 is configured to perform: determining whether a unified service mode is enabled; in response to determining that the unified service mode is enabled, starting a service manager; and in response to determining that the unified service mode is not enabled, starting a background service process corresponding to each application program.

The unified service mode refers to a background service process that executes an associated plurality of applications using a single service manager. The system of the display device can be simultaneously provided with the service management program and the background service process of each application program, when the service management program is started, the background service process of each application program does not run (namely, the background is not maintained), but the service management program is resident in the background to monitor events and control the business processing of each application program; and when the unified service condition is not met, the service management program does not run in the background, but starts the background service process of each application program to perform one-to-one background service management.

The service manager is started only when the unified service mode is enabled by the system, i.e. the system currently supports the service manager to manage background service processes of multiple applications, otherwise the interception and alert processing service is started by the background service process of each application, specifically, the controller 250 is configured to determine whether to enable the unified service mode as follows:

after a display device is started, judging whether the service management program supports a unified service mode or not, and judging whether an application program associated with the service management program supports the unified service mode or not; determining that a unified service mode is enabled if the service manager supports a unified service mode and an application associated with the service manager supports a unified service mode; determining that unified service mode is not enabled if the service manager does not support unified service mode and/or an application associated with the service manager does not support unified service mode.

After the service management program is installed on the display device, for example, in some application scenarios, the unified service mode may be limited or not suitable for being enabled, so that the service management program cannot support unified background service management of multiple applications, and therefore it is necessary to determine whether the service management program supports the unified service mode; however, some application programs installed in the android system may not support the unified service mode, for example, the application program is updated and the service logic is changed, but the service management program does not have the service logic updated synchronously, so that the service management program cannot effectively prompt the application program to process the service, and the application program is not suitable for performing background service management by using the service management program, and therefore, it is also necessary to determine whether the application program associated with the service management program supports the unified service mode. The unified service mode can be started only when the service management program and the application program both support the unified service mode, the controller starts the service management program to realize the unified management of the accurate background service processes of the multiple applications, and if at least one of the service management program and the application program does not support the unified service mode, the service management program is determined not to be started, but the background service process corresponding to each application program is started.

Since the service management program is associated with a plurality of application programs, in the foregoing embodiment, as long as at least one application program does not support the unified service mode, the service management program is not started, but the background service processes corresponding to all the application programs are started, that is, the service management program and the background service processes of each application are not started at the same time. In some embodiments, for example, when the number of the applications that do not support the unified service mode is small, the background service process of the part of the applications may be started to perform independent service, and other applications that support the unified service mode may be uniformly serviced by the service manager; when the service management program monitors the relevant events of the application program which does not support the unified service mode, the service management program does not process the event information of the application program, does not send indication information to the application program, or can close the event detection module corresponding to the application program which does not support the unified service mode.

After the service manager is started, as shown in fig. 7, the service manager is configured to: loading the service logic of each application program and monitoring each event detection module; in response to monitoring event information sent by a target event detection module, determining a target application program corresponding to the target event detection module; determining a triggered event according to the event information and the service logic of the target application program; and generating indication information according to the triggered event, wherein the indication information is used for enabling the target application program to process the service corresponding to the triggered event. And when the target application program finishes processing the service indicated by the service management program, the target application program can automatically quit, and the service management program continues to monitor the event.

The service management program has pre-stored the service logic of each application program, so the service logic of each application program is loaded for standby after starting. In some embodiments, referring to fig. 6, the service management module 500 may further be subdivided into an event monitoring module 502 and a service module 503, the event monitoring module 502 is connected to the plurality of event detection modules 501, the event monitoring module 502 is equivalent to an interface for receiving event information, and after the service management program is started, when it is monitored that event information comes, the event monitoring module 502 may send the event information to the service module 503. The service module 503 stores business logic of a plurality of associated applications, each application has a mapping relationship with an event detection module, and each monitored event information can determine a target application corresponding to a target event detection module from which the event information originates through the mapping relationship, for example, an application identifier can be set in association with each event detection module 501. The service module 503 determines which event is triggered according to the event information and the service logic corresponding to the target application program, for example, the user clicks the control a on the call interface of the video call application, the event detection module detects that the user clicks the control a, and sends the event information to the event monitoring module 502, if the event information is the click control a, the service module 503 determines that the click control a triggers the event that the user hangs up the video call according to the service logic of the video call application, generates corresponding indication information, and sends the indication information to the video call application, the video call application receives and responds to the indication information, and the executed service is to destroy the current call interface to hang up the current video call. It should be noted that fig. 6 is only an exemplary module architecture of the service manager, and does not represent an actual hardware structure.

In some embodiments, fig. 8 illustrates a process flow of a controller when an application is installed or updated, including:

step S101, judging whether the first application program has the authority of joining the service management program. The first application program is any application program requiring new installation or version update, and is not particularly limited to the serial number of the application program. When the first application program has the authority of joining the service management program, executing the step S102; otherwise, if the first application does not have the authority to join the service manager, step S106 is performed.

Step S102, determining whether the unified service mode is enabled. If it is determined that the unified service mode is enabled, step S103 is performed, and otherwise, step S106 is performed.

Step S103, acquiring the communication authority of the service management program, wherein the communication authority is used for allowing the application installation process of the controller to write data into the service management program; the data includes communication rules of the first application with the service manager. The purpose of obtaining the communication authority is to allow the application installation process of the controller to write data, such as a communication rule and the like, into the service management program, where the communication rule specifies how the service management program sends content, such as instruction information and the like, to the application program, and the data described herein may also include other data required for implementing the service management program to perform business process control on the application program, and may be specifically set according to an actual application. If there are no specific communication rights, a default right is selected.

Step S104, storing the business logic of the first application program in a preset path. The preset path may be a local directory of the first application program, a directory specified by the service manager, or a fixed directory established in the display device system, and the preset path is not limited.

And step S105, prompting the service management program to acquire and install the business logic of the first application program from the preset path. For example, the controller may send a prompt message to the service manager to prompt the service manager to access the preset path to acquire and install the corresponding service logic.

The service logic of the first application program is stored in a storage address corresponding to a fixed path, the service management program can conveniently access a preset path after receiving the prompt message, so that the service logic of the first application program is obtained, the service logic is synchronously installed in a memory of the service management program, if the first application program is a newly installed application program, an event detection module corresponding to the first application program can be newly added, and if the first application program is an application program updated to an old version, the corresponding event detection module can be updated, so that the service management program can accurately monitor event information related to the first application program, and indication information is generated to control the first application program to process services matched with the event information.

And step S106, installing the background service process corresponding to the first application program, and storing the service logic of the first application program in a preset path.

When the first application program does not have the authority of adding the service management program or the system does not support the unified service mode, a background service process corresponding to the first application program needs to be installed independently, and the background service process is used for independently processing event monitoring and indicating business processing of the first application.

In some embodiments, such as application a, the original version is 2.0, the service manager has business logic of application a2.0 version installed, and when application a is updated to 3.0 version, the service manager also has business logic of application a2.0, and then the service manager still listens for events and indicates business processing of application 3.0 according to the business logic of 2.0 version. After the application program A is upgraded, the service logic of the application program A3.0 can be stored in the preset path, so that the application program A can monitor events and instruct to process services through the corresponding background service process, when the service management program is updated, the preset path can be automatically accessed to obtain the newly added service logic of the application program A3.0, then the service logic of the application program A3.0 is installed in the service management program, and after the service management program is updated, the background service can be performed on the application program A3.0.

In some embodiments, for example, if the application B is newly installed, the service management program does not have the service logic of the application B installed, and it is obvious that the application B cannot support the unified service mode, the service logic of the application B may be stored in the preset path, when the service management program is updated, the preset path is automatically accessed to obtain the newly added service logic of the application B, then the service logic of the application B is installed in the service management program, and meanwhile, an event detection module corresponding to the application B is added, and after the service management program is updated, the application B can be subjected to background services such as event monitoring and service processing indication.

In some embodiments, for example, when the application C is installed or updated, a service manager is not installed in the display device system, then the background service process C corresponding to the application C is installed, the background service process C performs background service on the application C, and prestores the service logic of the application C in a preset path, when the system installs the service manager, the preset path is accessed, the service logic of the application C is obtained and installed in the service manager, and meanwhile, an event detection module corresponding to the application C is added, so that unified background service management of the application C and other applications is realized.

In some embodiments, FIG. 9 illustrates a process flow of a controller when a service manager is installed or updated, comprising:

step S201, when the service manager is updated, acquiring an application list, where the application list includes all application programs having a right to join the service manager.

In some embodiments, an application list may be created, and the application list may be changed, for example, according to an update of the service logic stored in the preset path, for example, if the service logic of the application program C is added to a directory of the preset path, a record of the application program C is inserted into the application list; for another example, if the service logic of the application program a2.0 is replaced with the service logic of the application program 3.0, the record of the application program a in the application list is kept unchanged; for another example, if the application D is uninstalled, the record of the application D is deleted from the application list. The applications added to the application list have by default the right to support the unified service mode.

Step S202, controlling the service management program to install the current business logic of each application program in the application list. After the installation is completed, the service management program can monitor the event and process the indication service for each application program in the application list.

When the service management program is installed or updated, the latest business logic of each application program in the application list is installed, so that the events of each application program in the application list can be accurately monitored and the business processing can be instructed.

In some embodiments, if the service manager supports unified service mode and the application also supports unified service mode, upon installation or update of the application, a prompt may be sent informing the service manager of the specified path in which the application was installed or updated, the service manager checking the service logic of the application upon subsequent updates, and installing the service logic of the application to the service manager.

In some embodiments, if the service manager supports the unified service mode and the application does not support the unified service mode, the application is updated independently without affecting the service manager; if the service management program does not support the unified service mode, the application program supports the unified service mode, if the unified service mode is limited to be used in the application scene, the service management program can not be updated, and if the unified service mode is not limited to be used in the application scene, the service management program can be updated according to actual needs.

At present, the updating frequency of the application program is obviously increased, after each application program is updated, the associated background service process also needs to be updated synchronously, and once the updating is asynchronous, the function and the service processing of the application program are abnormal. In the application, the application programs and the service management programs can be updated relatively independently, the service functions are dynamically adapted, each application program does not need to be configured with a corresponding background service process, but a single service management program monitors events and controls the service processing of a plurality of application programs, the unified management of the plurality of application service processes is facilitated, even more application programs are subsequently added, the memory resources of the system cannot be occupied in an accumulated mode, the occupation of the memory resources of the system is reduced, and the processing performance of the operating system is ensured.
