In some embodiments of the present application, a user interface may be displayed on the display 260, where the user interface may be a specific target image, for example, various media materials obtained from a network signal source, including video, pictures, and so on. The user interface may also be some UI interface of the display device 200, such as a system recommendation page or the like. The user interface may also be a home page. The homepage is a user interface after the display device 200 is started, and the homepage can provide resources such as application entries, recommended content and the like for the user. In some embodiments, the homepage may be of various types, such as a homepage in a business mode or a homepage in a home mode, with the homepage presenting different display content in different modes, which may be reflected in a specific interface layout and recommended content.

The home page of the display device 200 is a page displayed by an application with a home page attribute. The home page attribute is an attribute for specifying the first page displayed after entering the application, i.e., an attribute for defining the interface displayed when the current application is opened. Only one application of the display apparatus 200 has a homepage attribute, so the display apparatus 200 has only one homepage, and the homepage attribute is an attribute preset in the application, and the user has no authority to modify. Therefore, if the user needs to customize the homepage, the homepage needs to be changed, and the whole machine is matched and modified. For example, when different hotels need to display customized homepages of hotels to users, homepages of original factory configuration of the display device 200 need to be changed, and meanwhile, the whole configuration of the display device 200 needs to be matched and modified, which is time-consuming and has poor user experience.

In order to achieve a quick switch home page and meet the user's customized home page requirements, some embodiments of the present application provide a display device 200. In order to facilitate understanding of the technical solutions in some embodiments of the present application, the following details of each step are described with reference to some specific embodiments and the accompanying drawings. Fig. 5 is a flowchart of a method for executing homepage display by the display device 200 according to some embodiments of the present application, as shown in fig. 5, where the controller 250 in some embodiments of the present application is configured to execute the following steps S1-S2, which are specifically as follows:

step S1: after the system of the display apparatus 200 is initialized, the current mode of the system is detected, if the current mode of the system is a preset mode, whether a target application is installed in the system is continuously detected, and if the target application is installed in the system, the homepage attribute of the preset application is deleted and the homepage attribute is added to the target application.

Before the system of the display device 200 is initialized, the display device 200 needs to be started, and a user input to start the display device 200 may be generated for the user by pressing a start key on the control device 100. The home page application needs to be started after the display device 200 is started so that the home page is displayed on the user interface of the display device 200. The homepage provides media information for the user to select. Wherein the system initialization may be the initiation of an AMS (activity management service). The AMS starts up in a system server process, and has the role of communicating with all four components (Activity, service, broadcastReceiver, content Provider) of an application, and the application starts up and opens up the interface of the home page, which needs to communicate with the AMS. It should be noted that, both the power-on of the display device 200 and the pressing of the home key start the process of displaying the homepage in this embodiment.

The detecting the current mode of the system may be by reading mode information of the current mode, and determining the current mode of the system according to the mode information. And reading the mode information of the current mode of the system, and if the current mode of the mode information display system is a preset mode, continuously judging whether the target application is installed in the system.

In some embodiments, the step of obtaining the mode information may include: after the display device 200 is powered on, a Boot up service (Boot) starts up the display device 200, and then the SystemServer sends the acquisition mode information to the cache. The mode information may be stored in a cache in the following manner: the mode information is information of a mode adopted by the display device 200 last time, and after the display device 200 is turned off, the mode information adopted before the shutdown is stored in a cache for being read when the display device is turned on next time. The cache transmits the fed back mode information to the system service, if the system service receives the mode information, a homepage application message is generated according to the mode information, and the homepage application message is transmitted to a desktop starter (host), and the desktop starter performs the subsequent step of starting the homepage application according to the mode information. If the mode information is not obtained from the cache (e.g., the user has not set the mode, where the setting may be the mode that the system was using the last time the display device 200 was used), then a default mode is employed to launch the default home application.

For example, the default mode may be a standard mode, and if the user does not set the mode, the system is started to the standard mode, and in the standard mode, a default home application a is started, and the home application a is used as a user interface presented to the user after the display device 200 is started. If the user sets the mode, for example, when the display device is used last time, the mode used by the system is a succinct mode, and the mode indicated by the mode information acquired by the display device is the succinct mode.

The preset mode is a mode set as a replaceable homepage, i.e., if the current mode of the system is the preset mode, it is supported to replace the application defaulted as the homepage with other applications. Illustratively, the default mode is set to replace the home page application from the default home page application a to the non-default home page application B, C …. If the current mode of the system is not the preset mode, the home page application may not be replaced from the default home page application A to the non-default home page application B, C …. The mode of setting the preset mode to the replaceable homepage may be a mode of supporting a third party application as a switch of the homepage application to be on.

After detecting that the current mode of the system is the preset mode, continuing to detect whether the target application is installed in the system. The target application of the present application is an application that does not have a homepage attribute before system initialization and is set to be bootable as a homepage.

The system may register as a homepage application by adding a homepage attribute (home attribute) to a certain application in a global profile (e.g., alives). The system will find the application registered with the homepage attribute at the first moment after the initialization of the system framework is completed, and then start it. The target application does not register the homepage attribute before the system is initialized, and the preset application registers the homepage attribute before the system is initialized, so that if the homepage attribute is not modified, the preset application is an application started by default, namely the default startup takes the page of the preset application as the homepage, and the target application refers to a third party application of a user for displaying the customized page.

In some embodiments, a method of detecting whether a target application is installed in a system may include the steps of: and scanning the installed application in the system, and determining the application added with the designated action and the starting permission as the target application, wherein the designated action is used as a replacement homepage action. That is, the added replacement homepage action and the startup right are two conditions for the application as the target application. If the application has both conditions, the application can be used as the next step of the target application to display the homepage, and if the application does not have both conditions, the application cannot be used as the target application to display the homepage. Illustratively, an application a and an application B are installed in the system, wherein the application a has added a replacement homepage action and a boot permission, and the application a can be determined as a target application. The application B does not add the boot permission although the replacement homepage action is added, or does not add the replacement homepage action although the boot permission is added, and cannot be determined as the target application. It should be noted that, all the target applications mentioned in the present application are applications that satisfy the above conditions, that is, all the target applications mentioned in the present application are applications that can be replaced by home applications, so the target applications will not be described in detail in other embodiments.

If it is detected that a target application is installed in the system, that is, an application exists in the system that can be started as a homepage application, the target application may be a user customized homepage application, homepage attributes of a preset homepage application (preset application) may be deleted, and homepage attributes may be added to the customized homepage application (target application). After the completion of the step S1, the following step S2 may be performed.

Step S2: instead of launching a preset application, a customized home application (target application) is launched. Therefore, the homepage can be quickly switched, and the requirement of a user for displaying customized homepage is met.

If the target application is not detected to be installed in the system, namely, no application which can be started as a homepage application exists in the system, namely, no user customized homepage application exists, the homepage attribute of the preset application is not deleted. After the completion of the step S1, the following step S3 may be performed.

Step S3: and starting a preset application.

In some embodiments, launching the home application (preset application or target application after adding the home attribute) may include the steps of: the desktop starter process initiates a start activity (startActivity) request to the system service process by adopting inter-process communication; after receiving the request, the system service process sends a request for creating a process to the hatching process; the hatching process derives a new subprocess, namely a homepage application process; the homepage application process initiates an additional application program request to the system service process through inter-process communication; after receiving the request, the system service process sends a request for planning to start the activity to the homepage application process through inter-process communication; an application thread of the home page application process) sends a transmission activity message to the main thread through the handler after receiving the request; after receiving the information, the main thread creates a target activity through a transmitting mechanism and calls back methods such as activity creation (onCreate (); the homepage application is formally started, starts to enter an active life cycle, executes the onCreate/onStart/onResume method, and can see the main interface of the application after the UI rendering is finished.

As can be seen from the above technical solutions, the display device 200 provided in the above embodiments determines the current mode of the system after the system is initialized. If the current mode of the system is the preset mode, then judging whether the system is provided with the target application or not. If the system installs the target application, the homepage attribute of the preset application is deleted, and the homepage attribute is added to the target application, so that the system starts the target application as the homepage and does not start the preset application as the homepage. Wherein the preset mode is a mode in which a replaceable homepage is set, the preset application refers to an application that already has homepage attributes before system initialization, and the target application refers to an application that does not have homepage attributes before system initialization and is set to be bootable as a homepage. According to the method and the system, when the current mode of the system is the preset mode and the target application is installed, the target application is started as the homepage and the preset application is not started as the homepage, and the target application can be a user customized application, so that the homepage can be quickly switched, the user customized homepage requirements are met, and the user use experience is improved.

The following is a specific application of the homepage display method provided in some embodiments of the present application in the customized homepage scene of the display device 200 for hotels:

Fig. 6 is a flowchart of dynamically replacing a homepage with a target application by the display device 200 for a hotel, and fig. 7 is a system frame diagram of dynamically switching homepages by the display device 200 for a hotel, wherein the method shown in fig. 6 can be applied to the system shown in fig. 7.

As shown in fig. 7, the system for dynamically switching home pages of the hotel display device 200 includes a third party application, a preset application, a hotel menu application, and an android frame. Wherein the third party application, if it is to be determined as the target application, is required to meet the following conditions including: the activity of the third party application needs to specify an action (the specific script is action: com. Android. Action. Replace_home); adding configuration of android standard determining the entry activity of the application (specific script is android.intent.action.MAIN) and configuration which can be implicitly started (specific script is android.intent.Default) into a manifest file (application function description file) of the third party application; boot startup authority (specific script android: directootaware= "true") is added. Since the homepage application is started earlier than other applications and needs to be started before boot complex is completed, the third party application needs to add a startup right to start as homepage.

action is an action that can be performed on the operation of the application. The action may be to uninstall the application, add a shortcut, and dial a phone number. And monitoring the unloading condition of the application program by utilizing the action, for example, the action is an unloading application program, the script corresponding to the action is android. In this embodiment, the action is to add a homepage attribute, and the script corresponding to the action is com.

The target application is replaced by a homepage application, and the hotel menu application is also required to meet the following conditions: the system is in hotel mode and the hotel menu application supports the switch of the target application as a home page in an on state. The mode information and the switch state information of the target application as the homepage are stored in the setting database.

As shown in fig. 6, the specific procedure of the hotel display device 200 to dynamically replace the homepage is:

the ASM is started, and the mode information and the switch state information of the target application serving as a homepage are read from a setting database. If the read mode information is the hotel mode and the switch state information of the target application as the homepage is on, then it is determined whether the target application has been installed in the system. If the read mode information is not hotel mode or the switch state information of the target application as homepage is off, the preset application is directly started.

If the system is in hotel mode and the switch state of the target application as homepage is on, if the target application is installed in the system, the homepage attribute of the preset application is removed, the homepage attribute is added to the target application, and then the target application is started as homepage, and the preset application is not started as homepage. The android system can pull up the homepage application after scanning is completed, and after the homepage attribute of the preset application is deleted and the homepage attribute is added to the target application, the application with the homepage attribute only has the target application, so that the interface of the target application can be pulled up at the moment to serve as a homepage entry. If the target application is installed, the whole machine analyzes the target application by adding the homepage attribute to the category in the Manifest file of the target application, so that the target application is the homepage application which can be identified by the android system. If the target application is not installed in the system, the android system can recognize that the homepage application is only a preset application, so that an interface of the preset application is pulled up to serve as a homepage entry.

Fig. 8 is a schematic diagram of a detection whether a target application is installed or not according to some embodiments of the present application, and as shown in fig. 9, whether the target application is installed or not in the detection system is detected by scanning an application installed on the whole machine through an android PMS (PackageManager Service, application program installation package management service). Specifically, the android PMS parses a manifest.xml file (global configuration file) of each application, detects whether specified action information (com.android.action. Replace_home) exists, if so, adds a category in the manifest.xml of the application of the specified action to a homepage attribute of the android standard, and deletes the homepage attribute of the preset application (deletes the homepage attribute of the category in the manifest.xml).

FIG. 9 is a flowchart illustrating yet another home page display method, as shown in FIG. 9, according to an exemplary embodiment, which may further include the following steps on the basis of the embodiment shown in FIG. 5:

in step S201, after the system is initialized, determining that the current mode of the system is a preset mode and at least two target applications are installed;

in step S202, in response to a user input selecting a first target application, deleting a homepage attribute of a preset application and adding the homepage attribute to the first target application;

in step S203, the first target application is launched as a homepage and the preset application is not launched as a homepage.

For example, after the system is initialized, it is detected that the current mode of the system is a hotel mode, and a target application a and a target application B are installed (the target application a and the target application B each satisfy the above three conditions as the specified action application), then a selection dialog box may be popped up in the user interface as shown in fig. 10. The selection dialog box comprises a target application A control and a target application B control. And if a control instruction of selecting the target application A control by the user is received, adding a homepage attribute to the target application A in response to the control instruction, and then pulling up the page of the target application A as a homepage entry. And if a control instruction of selecting the target application B control by the user is received, adding a homepage attribute to the target application B in response to the control instruction, and then pulling up the target application B to serve as a homepage entry. In this exemplary embodiment, if there are a plurality of target applications in the system, an application to which a homepage attribute needs to be added may be determined according to parameters such as the frequency of use and update time of each target application. Therefore, not only can the homepage be quickly switched, but also different homepage applications can be selectively started according to the current use condition.

In some embodiments, after deleting the home page attribute of the preset application, the preset application remains in the system as a normal application, so that the preset application can be normally used on the display device even though the interface of the target application is used as a home page portal. In some embodiments, the preset application may also be set to be hidden in the system directly after the home page attributes of the preset application are deleted. For example, if the preset application only has a function of displaying the animation when the home page is displayed, and the display of the animation when the home page is not needed, the preset application can be hidden from the home page interface, so that the home page interface is simpler.

In the above embodiment, after the system is initialized, the display device 200 first determines whether the current mode of the system is the preset mode, and if the current mode is the preset mode, continues to determine whether the target application is installed. In some embodiments, after the system is initialized, the display device 200 may first detect whether the target application is installed in the complete machine, and then determine the mode information. If the designated target application is not installed, the default home application may be launched directly in the default mode as the home page, or the preset application may be launched in the preset mode as the home page. If the target application is installed, continuing to judge the current mode of the system, if the current mode of the system presets the mode, deleting the homepage attribute of the preset application and adding the homepage attribute to the target application, and starting the target application after adding the homepage attribute as the homepage, without starting the preset application as the homepage. If the target application is not installed, the step of starting the preset application as the homepage can be directly executed, and the step of reducing judgment improves the homepage display efficiency.

In the above-described embodiment, the target application is installed in the system, but in some embodiments, the target application may not be installed in the system, but an installation package of the target application is stored in a preset storage area. FIG. 11 is a flowchart illustrating yet another home page display method, as shown in FIG. 11, according to an exemplary embodiment, which may further include the following steps on the basis of the embodiment shown in FIG. 5:

in step S301, after the system is initialized, if the current mode of the system is a preset mode and the target application is not installed, the preset storage area is scanned.

After the preset storage area is scanned in step S302, if the preset storage area stores the installation package of the target application, the target application installation package stored in the preset storage area is installed, and the installation of the target application is completed.

In step S303, deleting the homepage attribute of the preset application and adding the homepage attribute to the installed target application;

in step S304, the target application after adding the homepage attribute is launched as the homepage, and the preset application is not launched as the homepage.

The present embodiment is equivalent to that the target application may be configured in a preset storage area, and if the target application runs erroneously in the system or is deleted erroneously, the target application installation package may be reinstalled after being loaded from the preset storage area. And the target application installation package in the preset storage area can be updated at any time or replaced by the installation package of other target applications, so that the target application can be updated or replaced according to the requirements. It should be noted that the preset storage area may be integrated with the display device 200, or may be external to the display device 200. If the preset storage area is located outside the display device 200, the preset storage area may also be updated without interrupting the normal display of the display device 200, for example, the installation package of the target application in the preset storage area is updated, or the installation package of the target application in the preset storage area is cleared.

The target application a is installed in the system in advance, but the target application is not installed in the system after being deleted by mistake, and an installation package of the target application a can be obtained from a preset storage area, and the target application a is installed in the system again. Alternatively, the installation package of the target application B may be acquired from a preset storage area, so as to replace the target application a installed in the system with the target application B.

Based on the above embodiment, if the target application has been installed in the system, it may also be determined whether there is an installation package of the target application of the updated version according to the version of the target application that has been installed. If there is an installation package of the target application of the updated version, the target application may be updated according to the installation package of the target application of the updated version.

Illustratively, version 1.0 of the target application a is already installed in the system, and if an installation package of the target application a is stored in the preset storage area, the version of the installation package may be detected. If the installation package version of the target application a stored in the preset storage area is 2.0, the target application a installed in the system may be updated according to the installation package version of the target application a of 2.0. Thus, the dynamic update of the target application can be realized, and the dynamic update of the customized homepage is realized.

In consideration of the possibility that the target application is not installed successfully, it may also be determined whether the target application in the preset storage area is installed successfully. The installation log of the display device 200 (for example, the android system may be stored in/data/system/package. Xml) records identification information (for example, a unique version number and a package name) of an application installed in the display device 200, and the identification information recorded in the installation log may be cleared after the terminal device is restored to factory settings, or after a certain application is uninstalled, the identification information corresponding to the application may be cleared as well. Therefore, whether the target application corresponding to the target application installation package is installed or not can be judged according to the identification information recorded in the installation log. If the installation log records the identification information of the target application corresponding to the target application installation package, the target application installation package can be judged to be installed. If the installation log records the identification information of the target application corresponding to the target application installation package, the target application installation package can be judged not to be installed. If the target application installation package is judged not to be installed, a dialog box can be popped up for the user to select to manually install the target application installation package.

Illustratively, the installation package of the target application a in the preset storage area is marked with identification information, and if the identification information X is recorded in the installation log of the read display device 200, it is determined that the target application a is installed. If the identification information X is not read from the display apparatus 200, it is determined that the target application a is not installed or the target application a is not updated.

In some embodiments, after the system of the display device 200 is initialized, a first control corresponding to the preset mode and a first control corresponding to the non-preset mode may also be displayed on the display 260, and the user may cause the system to enter a different mode by selecting a different control. For example, in response to a user input selecting a first control corresponding to a preset mode, causing the system to enter the preset mode, or in response to a user input selecting a second control corresponding to a non-preset mode, causing the system to enter the non-preset mode. The system may be installed with different target applications in different modes.

Illustratively, as in the user interface shown in FIG. 12, after system initialization of the display device 200, an A control corresponding to the business mode and a B control corresponding to the home mode are displayed on the display 260. If the user selects the A control, then in response to user input selecting the A control, the system enters business mode, jumping from the user interface shown in FIG. 12 to the user interface shown in FIG. 13. If the user selects the B control, the system enters home mode in response to user input selecting the B control, jumping from the user interface shown in FIG. 12 to the user interface shown in FIG. 14.

Wherein both the business mode and the home mode are configured to support the target application as a homepage application launch. The business model may install a target application a, where the target application a may be configured to present the merchant's merchandise. After the system enters the business mode, the homepage attribute of the preset application is deleted and the homepage attribute is added to the target application A, so that the target application A can be started as the homepage, and the requirement of displaying the customized homepage of the business is met. The home mode may install a target application B, where the target application B may be configured to expose media assets. After the system enters the home mode, the homepage attribute of the preset application is deleted and the homepage attribute is added to the target application B, so that the target application B can be started as the homepage, and the requirement that a user can watch media resources after starting up is met. Therefore, the same display device can meet different use scenes, and the suitability of the display device is improved.

In some embodiments, a control to exit the current mode may also be configured on the current home interface of the display device 200, from which the system may exit in response to user input selecting the exit current mode control. The system exits the current mode and can return to the interface of the selection mode or automatically enter the default mode.

Illustratively, a control to exit the current mode is configured in the user interface in the business mode as shown in fig. 13, and in response to a user input selecting the control to exit the current mode, the system exits from the business mode, may jump from the user interface shown in fig. 13 back to the user interface shown in fig. 12, or jump to the user interface in the default mode shown in fig. 15 (an interface that may directly display the home application in the default mode). In response to user input selecting the exit current mode control, a mode list, including a plurality of mode options, may be displayed on the exit current mode control, as in the user interface shown in FIG. 16. The different mode options may be selected by moving the selector so that the system enters the mode selected by the selector.

In some embodiments, a plurality of applications may also be set as target applications, and if the current mode of the system is a preset mode, after deleting the homepage attribute of the preset application, the homepage attribute is added to the plurality of target applications at the same time, and then the plurality of target applications are started as homepages. Illustratively, when the current mode of the system is detected as a commercial mode (a mode of replaceable homepage) and the target application a and the target application B are installed, the homepage attribute of the preset application is deleted and then the homepage attribute is added to the target application a and the target application B at the same time. The target application A is used for displaying the development history of the merchant, and the target application B is used for displaying main products of the merchant. After the homepage attribute is added to the target application a and the target application B at the same time, as in the user interface shown in fig. 17, the interfaces of the target application a and the target application B may be simultaneously displayed on the display 260. Thus, if the user needs to modify a certain area of the homepage, only the target application where the area needs to be modified is needed to be adjusted, and all target applications do not need to be adjusted.

In some embodiments, if the system is in a preset mode but it is detected that the target application is not installed in the system, an installation package of the target application may also be obtained from the server 400. FIG. 18 illustrates a flow diagram of interactions of a display device and a server in some embodiments. After the system of the display apparatus 200 is initialized, if it is detected that the system is in a preset mode but a target application is not installed in the system, the display apparatus 200 transmits a target application acquisition request to the server 400. The server 400 here may be a system-specific server, for example, a server 400 that has established an association relationship with the current display apparatus 200.

When the display device 200 establishes an association relationship with the server 400, the server 400 may acquire the device identification of the display device 200. The device identification may be used to uniquely identify the device, thereby distinguishing between different devices. In generating the Device identification, the server 400 may acquire Device information of the display Device, which may include a Device ID of the display Device 200, such as a Device ID, and may also include a Device address of the display Device, which may be a physical address, such as a MAC address. And splicing the device ID and the MAC address of the display device to obtain a spliced character string, namely the device identifier of the display device. After the server 400 obtains the device identifier of the display device 200, the display device 200 may use the unique access token and the device identifier to obtain data from the server 400 by binding the device identifier to a unique access token, so that the display device 200 and the server 400 establish an association relationship based on the above method.

Based on the association relationship, the target application installation package acquisition request carries an access token and a device identifier. Different device identifications may correspond to different target application installation packages. After receiving the target application acquisition request, the server 400 searches whether an installation package of the target application corresponding to the device identifier exists in the server 400. If there is an installation package of the target application in the server 400, the server 400 feeds back the installation package of the target application to the display apparatus 200. After receiving the installation package of the target application, the display device 200 installs the target application according to the installation package of the target application. And deleting the homepage attribute of the preset application, and adding the homepage attribute to the installed target application. Then the home page application identified by the system only has the target application, and the interface of the target application is pulled up to serve as a home page entry, but the interface of the preset application is not pulled up to serve as the home page entry.

The present embodiment is exemplarily applied to the following scenarios: the joined hotel a needs to present a unified home interface (e.g., the hotel display device needs to uniformly install the target application B), the display device 200 is in a commercial mode after startup and the installation of the target application B is not detected in the system, and the display device 200 may send an acquisition request of the target application B to the hotel a official server 400. Since the display device 200 has established an association with the hotel a official server 400, the hotel a official server 400 can feed back the installation package of the target application B to the display device 200 according to the acquisition request. After the display apparatus 200 acquires the installation package of the target application B, the target application B is installed in the system. And deleting the homepage attribute of the preset application, adding the homepage attribute to the target application B, and pulling up the interface of the target application B to serve as a homepage portal, so that the display device 200 can display the homepage interface unified by the hotel A.
