The display device generally has an open operating system, has an open application platform, supports function expansion, can install various application programs according to the needs of users, and provides diverse services to the users through the application programs. In order to improve and enhance the functionality and performance of applications, repair known vulnerabilities and errors, add new functionality and features, etc., upgrades to the applications are required.

In some related technologies, an upgrade of an application program is generally detected by using a package name (package name) and a Version Number (Version Number) of the application program, and if the application program is detected to have a new Version, the application program is installed according to an installation package corresponding to the new Version, so as to implement the upgrade of the application program.

It should be appreciated that package names, also known as application identifiers, are information representing applications in application development, are unique and identifiers used to characterize applications, and are typically named by way of reverse domain names (Reverse Domain Name) to ensure uniqueness; the package name not only can be used for distinguishing different application programs, but also can be used for rights management, application program search and the like in operating systems such as Android, iOS and the like.

And, a version number, which is a digital identifier for identifying the version of the application, for distinguishing between different versions of the application to ensure that the user can use the latest version of the application, typically named in the form of x.y.z, where X represents a major version number, Y represents a minor version number, and Z represents a revision version number.

In some related art, the process of upgrading an application program in a display device generally includes detecting an update, downloading the update, and installing the update, and specifically includes the following:

The application first needs to detect if a new version is available. The process of detecting updates requires communication with the server to determine if there is an updated version. Generally, an application program upgrade needs to send a request to a server, acquire information about the version number of the latest version of the application program, and then compare the information with the version of the local application program to determine whether the upgrade is needed.

If it is detected that a new version of the application is available, the application needs to be updated by downloading. This process requires communication with the server over a network connection and downloading a new application package file from the server. When downloading the application package file, network bandwidth, network stability and other factors are generally required to be considered so as to ensure the smooth progress of the downloading process and avoid the occurrence of errors in the downloading process.

In some related technologies, if it is detected that a new version of application program is available, a prompt message is popped up or displayed in the currently running old version of application program, and the user is queried whether the new version of application program is needed to be updated.

After the downloading is completed, the application program needs to be installed and updated, including: uninstall the old version of the application and install the new version of the application. In this process, the application needs to ensure the correctness of the uninstallation and installation process.

In the process of upgrading the application program, the application program of the old version running at present is firstly terminated, and after the upgrading is completed, the application program which is upgraded into the new version is restarted; in the process of upgrading the application program, the user can perceive that the application program is closed and restarted, even in the process of upgrading some application programs, the user can perceive that the upgrading message prompts, so that the user can use the device to pause, and experience is poor.

In the process of upgrading an application program, in order to avoid the perception of closing and restarting the application program by a user and improve the experience of the user, the embodiment of the application provides display equipment and an upgrading method of the application program, and the method comprises the steps of firstly sending an upgrading detection request to a server based on a package name and a version number in identification information of an initial application program, and then waiting for a message replied by the server; if the received message representation detects that the target application program with the version number higher than that of the initial application program exists, receiving an installation package of the target application program with the package name different from that of the initial application program from a server, and installing the target application program, wherein the initial application program is normally used in the process of installing the target application program; in this manner, after the display device is restarted, the initial application is replaced with the target application. Therefore, the method and the device can install the target application program in the background in the normal use process of the initial application program by acquiring the target application program which is higher than the version of the initial application program, different from the package name of the initial application program and belongs to the same application program as the initial application program, and replace the initial application program by the target application program after restarting the display equipment, so that the user is prevented from perceiving that the initial application program is closed and the target application program is restarted in the upgrading process of the application program, the application program is not required to be interrupted, and the user experience is improved.

In order to facilitate further understanding of the technical solutions in some embodiments of the present application, the following describes in detail a technical method for upgrading a display device and an application program in combination with some specific embodiments and accompanying drawings, and how the technical solutions solve the above technical problems. Embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments. It will be apparent that the described embodiments are some, but not all, of the embodiments of the application.

The display device comprises a display and a first processor, and the first processor is connected with the display screen; the display device may be in data communication with a server. The server may provide the application programs, and the content and interaction of each application program, to the display device, and may be a cluster, or may be multiple clusters, and may include one or more types of servers, for example, an application server, a server corresponding to a desktop application, and so on.

FIG. 5 is a timing diagram illustrating an upgrade method for an application program in a display device according to some embodiments of the present application, where, as shown in FIG. 5, a first processor is configured to perform the following steps:

S510, an upgrade detection request is sent to the server based on the identification information of the initial application program.

That is, the upgrade detection request is sent to the server, where the upgrade detection request carries identification information of the initial application program, where the identification information of the initial application program includes at least a packet name and a version number of the initial application program.

The detection request typically occurs at the start-up of the initial application or when the initial application is running in the background, that is, the upgrade detection request is a request from the initial application to the server to detect whether the version of the currently running initial application is the latest version.

In some embodiments, the identification information further includes device information such that the server determines suitability and compatibility of the application based on the received device information (e.g., device model number, operating system version, etc.).

In some related art, the package name of an application has a role in its upgrade process in determining that a new version of the application and an old version of the application are for the same application by the package name of the application. That is, the server is allowed to perform the positioning of the version library of the application by package name and check the application version to confirm whether a new application version exists.

S520, receiving the message replied by the server.

The server detects based on the received upgrade detection request, and returns the detection result to the display device.

In some related art, when an application issues a new version, the new version of the application must use the same package name as the previous old version of the application. Otherwise, the new version of the application will be considered an entirely different application than the previous old version of the application, and will not be recognized by the application store's corresponding server as an update to the old version of the application.

In the embodiment of the application, the old version application program and the new version application program in the server are different versions of the same application program, but the old version application program and the new version application program have different package names, and the old version application program and the new version application program are stored in the same version library.

It should be understood that after receiving an upgrade detection request of an initial application program sent by a display device, the server screens an alternative application program with the largest version number from a corresponding version library, compares the version number of the alternative application program with the version number of the initial application program, and determines a target application program if the version number of the alternative application program is greater than the version number of the initial application program, wherein the target application program is an application program which belongs to the same application program as the initial application program, is higher than the version number of the initial application program, and is different from the package name of the initial application program.

In some embodiments, if it is detected that a new version of the target application program exists, the message replied by the server carries information of the new version of the target application program, where the information may include version information of the new version of the target application program and corresponding device adaptation information.

In some embodiments, if it is detected that there is no new version of the target application, the message replied by the server does not carry information about the new version of the target application.

And S530, if the message characterization detects that the target application program with the version number higher than that of the initial application program exists, receiving an installation package of the target application program from the server.

The server judges that the target application program and the initial application program are different versions of the same application program, and the package name of the target application program is different from the package name of the initial application program.

In some embodiments, the package name of the target application is different from the package name of the initial application, and it may be that the portion of the package name of the target application is different from the portion of the package name of the initial application.

The package name of an application is typically named by way of an inverted domain name, which may include: company domain name, company name, application platform name and application program name to which the program belongs; it should be appreciated that the package name may also include information for other applications, such as application platform names, etc.

As one example, the package name of the initial application is: com.xxx.yyy, the package name of the target application may be: com.XXX.YYYYB, wherein com is the company domain name to which the program belongs, XXX is the company name, YYY is the initial application name, and YYYB is the target application name.

In the above example, the package name of the initial application and the package name of the target application are different, in which there is part of the same information (company domain name and company name to which the program belongs) and part of the different information (application name).

In some related art, the display device is configured to determine whether the initial application needs to be updated according to the message replied by the server, and may prompt the user to download and install a new version of the target application.

In the embodiment of the application, if the message characterization detects that the target application program exists, the user is not required to be prompted or inquired whether the initial application program is to be updated, and the interruption of the use of the user in the process of upgrading the application program is reduced.

It should be understood that, in the process of receiving the installation package of the target application program from the server, the download address of the target application program may be received from the server, and then the display device downloads the installation package of the target application program according to the received information and download address of the target application program.

S540, installing the target application program.

It should be appreciated that the initial application may still be used normally during installation of the target application, and that there is no impact on each other.

In some embodiments, during installation of the target application, the icon controlling the target application is not displayed and the system base components, including the broadcast registry and the content provider, are deactivated.

In some embodiments, before installing the target application program for the display device, it is further required to determine whether the target application program and the initial application program are different versions of the same application program, and after determining that the target application program and the initial application program are different versions of the same application program, install the target application program according to the received installation package of the target application program.

The method comprises the steps of judging whether the target application program and the initial application program are different versions of the same application program or not according to a strategy which is pre-agreed between the application program which possibly needs to be updated and an operating system of the display device, and achieving that the installation of the target application program and the normal use of the initial application program are not affected by response modification of the operating system and the application program.

Taking the display device of the Android operating system as an example, when the target application program is installed, the influence between the target application program and the initial application program can be avoided by modifying a package management service (Package Manager Service, abbreviated as PMS).

The PMS is a core service in the Android operating system, and is used for managing an application package and maintaining all applications installed in the operating system and all information of the applications. The PMS may manage all installed applications in the operating system and maintain information related thereto, such as version of the applications, component information of the applications, rights required for the applications, etc.; the PMS can process the installation and uninstallation operation of the application program and carry out necessary upgrade and update; the PMS can control the access authority of an application program in the operating system, and allow or prohibit the application program from accessing system resources; the PMS can load and analyze the manifest file of the application program, and process operations such as starting, stopping, suspending and the like of the application program; the PMS may optimize the installation and uninstallation operations of the application, etc.

As an example, when the target application program is installed, modifying the attribute of the icon of the target application program in the main page of the target application program, so as to avoid the icon display of the target application program, and simultaneously, disabling basic components such as a content Provider (Provider) and broadcast registration in the Android operating system corresponding to the target application program, so as to prevent the target application program from being installed in conflict with the initial application program, thereby causing the installation failure of the target application program; and the situation that the function of the target application program is pulled up by mistake in the using process of the initial application program is also prevented, so that the initial application program can be normally used in the installing process of the target application program.

It should be understood that, based on the related art, the icons before and after the application program is upgraded may not change, and the icon of the target application program may not be displayed by modifying the attribute of the icon of the target application program in the main page of the target application program, so as to avoid interference caused by user use when both the icon of the target application program and the icon of the initial application program are displayed.

In some embodiments, if the icon of the target application and the icon of the initial application change, the attribute of the target application icon in the main page of the target application may not be modified during the installation of the target application, that is, the target application icon may be used.

In some embodiments, if the icon of the target application and the icon of the initial application change, but the change is relatively small, it may be necessary to modify the attribute of the icon of the target application in the main page of the target application, that is, disable the icon of the target application, see the icon 10 of the target application shown in fig. 6, and see the icon 20 of the initial application shown in fig. 7, although the icon 10 shown in fig. 6 changes relative to the icon 20 shown in fig. 7, the user may understand that the change is the same application, and if both the icon of the target application and the icon of the initial application change, it is still necessary to modify the attribute of the icon of the target application in the main page of the target application, so that the icon of the target application is not displayed.

The Provider is an important component in the Android operating system and is used for managing data in application programs. Through Provider, the application program can share data to other application programs or read data from other application programs, and the security and privacy of the data are ensured through authority control. The application may store the data in an internal database or in a file system or other data source using a ContentProvider.

In order to ensure the security and privacy of the data, the operating system can control the authority of the Provider, and only the data provided by the Provider can be accessed under the condition that the corresponding authority is obtained. The application program can access the data provided by the Provider through the contentdesolver object, which communicates with the Provider to read and write the data.

Broadcast is one way of communicating between application components, by registering and sending the broadcast, the application can perform various functions such as starting a service, sending a notification, and updating an interface, etc.

In some embodiments, after the target application is successfully installed, the process of the target application may be started, and the target application may be initialized, because the package names of the target application and the initial application are different, and the starting of the process of the target application does not affect the running of the initial application.

The initialization of the target application program comprises the processes of installing and optimizing the plug-in of the target application program, downloading and caching cloud data, and the like, and the process of loading data can be started and completed rapidly in the next normal use process of the target application program through the initialization of the target application program.

Dex files are often used in plug-ins to store plug-in code, and thus, during the installation of the plug-ins, the installation of Dex is required so that application package (Android Application Package, APK) files containing the Dex files can be loaded.

In some embodiments, during the installation of the target application, the PMS may scan (e.g. scan android management. Xml) basic components of the system, and if it is detected that registration information that conflicts with the initial application exists in the target application, no error may be generated, and the registration information of the component may be directly ignored or deleted, so that the installation of the target application may be completed.

Among them, android management. Xml is a core file in an application, which contains all information of the application, such as package name, SDK version, application component (activity, service, etc.), application rights, etc.

S550, after the display device is restarted, the initial application program is replaced by the target application program.

It should be understood that in the embodiment of the present application, the upgrade from the initial application program to the target application program is implemented after the display device is restarted, so as to display the upgraded target application program to the user.

In some embodiments, after the display device is restarted, the applications are rescanned; comparing the initial application program with the same user identification with the target application program, and setting the starting path as the target application program with high version number; and in response to the operation of starting the target application, sharing the data of the initial application to the target application based on the application signature information and the user identification of the target application that are the same as the initial application.

Taking the display device of the Android operating system as an example, the user identifier is userid, and userid is an integer and is used for identifying the user ID of the currently running application program. When each application program is installed, an independent user ID is created, so that the application program has independent running environments in aspects of a file system, network connection and the like, the userid is closely related to the access authority of the application program to the system resource, and the Android system can control the access authority of the application program to the system resource according to the userid of the application program.

It will be appreciated that userid is used to identify users and groups of users in the system, each having a unique user ID that is consistent across the file system for all files of that user or group of users.

In some embodiments, after restarting the display device, rescanning each application program through the PMS, setting a start path to be the target application program, and deleting an attribute of an initial application program icon in a main page of the initial application program, avoiding icon display of the initial application program, and disabling basic components of the initial application program, such as Provider, broadcast registration, and the like; and the icons of the target application program which is disabled before the target application program and basic components such as Provider, broadcast registration and the like in the Android operating system corresponding to the target application program are disabled, so that the target application program can be seen by a user and can be normally used.

In some embodiments, if the display device is restarted, the user may start the target application by clicking on the displayed icon, which may be considered the initial application as the open application.

In some embodiments, the target application may be launched by the system, e.g., the initial application and the target application may each correspond to a desktop application, and the target application may be launched by the system.

In some embodiments, the data of the initial application is disabled and deleted while the data of the initial application is shared with the target application based on the same application signature information and user identification of the target application as the initial application.

In some embodiments, sharing the data of the initial application to the target application is copying the data of the initial application under an installation directory of the target application; and disabling the initial application and deleting the data of the initial application.

According to the embodiment of the application, the target application program which is higher than the version of the initial application program, different from the package name of the initial application program and belongs to the same application program with the initial application program is obtained, so that the target application program can be installed in the background in the normal use process of the initial application program, and the target application program is used for replacing the initial application program after the display equipment is restarted, so that the user is prevented from perceiving that the initial application program is closed and the target application program is restarted in the upgrading process, the application program is not required to be interrupted, and the user experience is improved.

In some embodiments, by receiving a message indicating that a target application program higher than the version number of the initial application program is detected through the reply message of the server, receiving an installation package of the target application program from the server, for the display device, there may be uncertainty that the target application program is a different version of the same application program as the initial application program, determining that the target application program is based on a preset determination policy in the display device, and improving the accuracy of upgrading the initial application program to the target application program in the display device, fig. 8 shows a timing interaction diagram of an upgrading method of a further application program in the display device in some embodiments of the present application, and before installing the target application program, the first processor in the display device is further configured to perform:

s610, acquiring a preset upgrading judgment strategy corresponding to the initial application program.

The preset upgrading judging strategy comprises a preset user identifier and a preset package name rule.

The preset upgrade judging policy is determined based on a preset user identifier and a preset package name rule, and it should be understood that the preset user identifier and the preset package name rule can be used for judging whether two application programs are the same application program, and in the related art, the two application programs can be judged to be different versions of the same application program through the uniqueness of the package name; in the embodiment of the present application, the package names of the target application program and the initial application program have different part information, so that it is necessary to further determine whether the two application programs are the same application program by combining a preset package name rule and a preset user identifier.

In some embodiments, the determination of the preset upgrade determination policy further includes application signature information of the application, it should be understood that the application signature information is a digital signature for identifying and ensuring validity and credibility of the application, and the presence of the signature information can ensure that the identity of the publisher of the application is truly reliable, and the application is not tampered with or impersonated by other applications. The application signature information may also be used to verify whether the application is authorized, and whether it contains unauthorized content or functionality.

In some embodiments, the determination of the preset upgrade determination policy may also include a system signature, it being understood that the system signature is a privileged signature of a system core component. Only developers authorized by the platform development team or device manufacturer can sign their own applications using the system signature. The system signature is mainly used to identify system level applications, such as rights manager, application store, etc., to ensure the integrity and security of the system applications.

It should also be appreciated that when the application signature information and the user identification corresponding to different applications are the same, the applications may share data.

The preset package name rule is used for judging package names of application programs of different versions, and it should be understood that the package names of the target application programs are different from those of the initial application programs in the embodiment of the application, that means that part of information is different, such as the application program names in the package names are different, other data information is the same, and whether the package names of different application programs belong to part of information in the embodiment of the application can be judged by the preset package name rule.

S620, determining that the relevance exists between the target application program and the initial application program based on the preset user identification, the user identification of the target application program and the user identification of the initial application program.

By comparing the preset user identification, the user identification of the target application program and the user identification of the initial application program, if the user identification of the target application program is the same as the user identification of the initial application program and is the same as the preset user identification, the relevance between the target application program and the initial application program can be determined, that is, the target application program and the initial application program are aimed at the same application program.

S630, judging whether the package name of the target application program and the package name of the initial application program meet the preset package name rule.

It should be understood that the package name of the target application is different from the package name of the initial application, but the package name is different, and it cannot be determined that the target application is a different version of the same application as the initial application, so it is determined whether the package names of the different applications are different from part of the information in the package name according to the embodiment of the present application through the preset package name rule.

In some embodiments, the preset package name rule is that only application names in the package names are different, and that there is a similarity or keyword match between the application names.

As an example, if the package name of the initial application is: com.xxx.yyy, the package name of the target application may be: com.XXX.YYYB, only application names are different, and the application names YYY and YYYB have similarity, so that the package name of the target application program and the package name of the initial application program can be judged to meet the preset package name rule.

If the package name of the initial application program is: com.xxx.yyy, the package name of the target application may be: com.XXX.ZZZB, only the application names are different, but the application names YYY and ZZZZB have no similarity, and the package name of the target application program and the package name of the initial application program can be judged to not meet the preset package name rule.

It should be appreciated that the determination of similarity between application names may be performed by a Jaro Winkler matching algorithm, a Levenstein distance algorithm (Levenshtein Distance), or the like.

In some embodiments, if the initial application program and the target application program have the same preamble, it may be further determined whether the package name of the target application program and the package name of the initial application program satisfy the preset package name rule through regular matching.

S640, if the package name of the target application program and the package name of the initial application program meet the preset package name rule, determining that the target application program and the initial application program belong to different versions of the same application program.

In some embodiments, if the package name of the target application program and the package name of the initial application program meet the preset package name rule, it is further required to determine whether the package name of the target application program and the application signature information of the initial application program are the same, and if the package name of the target application program and the application signature information of the initial application program are the same, it is determined that the target application program and the initial application program belong to different versions of the same application program.

And the accuracy of upgrading the initial application program to the target application program in the display device is improved by adding the decision of the target application program and the initial application program based on the preset decision strategy in the display device.
