Detailed ways

It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

The present invention provides an application list synchronization method. In the first embodiment of the application list synchronization method of the present invention, referring to FIG. 1, the application list synchronization method includes:

Step S10, when the shortcut application preset in the display terminal detects an instruction to display the application list, obtain the latest version of the remote blacklist in the preset server;

A blacklist (that is, a blacklist configuration file) is preset in the preset server (that is, the remote server corresponding to the display terminal, and the server can provide data update services for the display terminal), and the blacklist in the server can be set according to national policies. The changes are updated in real time and can be downloaded and updated by the display terminal, so that after the display terminal leaves the factory, the server can still update the blacklist of the display terminal to ensure that the application list displayed by the display terminal complies with national policies and avoid policy risks.

After the display terminal is powered on and started, if the shortcut application preset in the display terminal detects the command to display the application list, for example, the Launcher (Android desktop launcher) application automatically receives the command to display the application list after the display terminal is started, and obtains the preset The latest version of the remote blacklist in the preconfigured server, that is, obtain the blacklist in the preconfigured server that is closest to the current national policy. Specifically, the display terminal detects from the server whether there is the latest version of the remote blacklist (here, the server will upload the latest version of the blacklist in time), that is, the background service of the display terminal uses a thread to connect to the preset server, detect Whether there is a remote blacklist in the server, and if it exists, the preset shortcut application in the display terminal will download the blacklist from the server, and store the blacklist in the application storage space corresponding to the preset shortcut application.

Step S20, comparing the local blacklist corresponding to the shortcut application with the remote blacklist;

Step S30, when the local blacklist is inconsistent with the remote blacklist, use the remote blacklist as a shortcut to apply a new local blacklist;

Compare the local blacklist stored in the application storage space of the preset shortcut application with the remote blacklist downloaded from the preset server. If the local blacklist is inconsistent with the remote blacklist, it indicates that the blacklist on the server has Update, the remote blacklist is used as the new local blacklist of the default shortcut application. Generally, the remote blacklist is stored in the directory storage space of the preset shortcut application, and the directory storage space needs to be adjusted by other applications, so Open permissions are required for remote blacklist storage, and the MODE_WORLD_READABLE attribute is used for data storage.

Step S40, controlling the shortcut application to generate a corresponding application list according to its local blacklist and displaying the application list on the display terminal.

Optionally, step S40 includes:

Step S41, obtaining all applications installed on the display terminal to obtain a complete application set;

Step S42, filtering out invisible applications in the complete application set to obtain a primary application set;

Step S43, controlling the shortcut application to filter out the blacklisted applications in the primary application set according to its local blacklist and generate a corresponding application list;

Step S44, displaying the generated application list on the display terminal.

There are many applications installed in the system of the display terminal, and the properties of some of the applications themselves are invisible. Therefore, when the preset shortcut application obtains the applications in the display terminal system, it first obtains all the applications installed on the display terminal to obtain the included Display the complete application collection of all applications on the terminal, and then need to add filter conditions, filter out the applications that do not need to be displayed through primary filtering, and obtain a primary application collection. Then the preset shortcut application further filters the primary application set according to its current local blacklist, that is, the applications on the local blacklist are filtered out from the primary application set to obtain a set of applications to be displayed, and the set of applications to be displayed The applications in are displayed on the display terminal in the form of an application list.

It can be understood that step S40 only describes displaying the application list according to the local blacklist, but the method described in step S40 is applicable to generating an application list according to all acquired or extracted blacklists mentioned above or below. For example, step S43 is changed to: control the shortcut application to filter out the blacklisted applications in the primary application set according to the blacklist acquired or extracted by the shortcut application and generate a corresponding application list.

In addition, after step S20, it also includes:

Step S50, when the local blacklist is consistent with the remote blacklist, keep the local blacklist of the shortcut application unchanged.

When the local blacklist stored in the application storage space of the preset shortcut application is consistent with the remote blacklist downloaded from the preset server, it indicates that the remote blacklist on the server has not been updated relative to the local blacklist, and the local blacklist is consistent with the current blacklist. According to the national policy, the local blacklist of the preset shortcut applications of the display terminal remains unchanged, and the preset shortcut applications use the free local blacklist to generate a corresponding application list.

Among them, it should be noted that the display terminal pre-stores a system blacklist in the corresponding location of the display terminal system directory (namely the system directory). Since the files in the system directory will not be cleared when the user restores the factory settings, if the server When something goes wrong and the preset shortcut application has not downloaded the remote blacklist from the server, and the local blacklist of the shortcut application itself cannot be extracted, the shortcut application can obtain the system blacklist from the system directory to use the system blacklist based on this system blacklist. The displayed application list is controlled to realize the synchronization of the application list.

That is, after the step S10, the following steps are also included:

If the remote blacklist is not obtained, obtain a local blacklist corresponding to the shortcut application;

If the local blacklist corresponding to the shortcut application is not obtained, extracting and displaying the system blacklist pre-stored in the terminal;

Controlling the shortcut application to generate a corresponding application list according to its local blacklist or the system blacklist to display on the display terminal.

In this embodiment, when the shortcut application preset in the display terminal detects an instruction to display the application list, obtain the latest version of the remote blacklist in the preset server; and then compare the local blacklist corresponding to the shortcut application with the remote blacklist The blacklist is compared; furthermore, when the local blacklist is inconsistent with the remote blacklist, the remote blacklist is used as the new local blacklist of the shortcut application; finally, the shortcut application is controlled to generate a corresponding application list according to its local blacklist and The application list is displayed on the display terminal, so that the preset quick application in the display terminal can synchronize its local blacklist with the remote blacklist in time, so that the local blacklist between the preset quick applications can also be synchronized , so that the application list displayed on the display terminal by the preset shortcut application is also synchronized, which solves the problem of inconsistency in the application list displayed on the display terminal by the shortcut application.

In addition, when the remote blacklist on the server is not obtained, the local blacklist of the shortcut application can also be obtained, or the system blacklist can be extracted to prevent the shortcut application from using all the applications installed on the display terminal as the application due to the vacancy of the blacklist. It is displayed in the form of a list, thus avoiding policy risks to a certain extent.

Further, on the basis of the first embodiment of the application list synchronization method of the present invention, a second embodiment of the application list synchronization method is proposed. Referring to FIG. 2 , in the second embodiment, the display terminal includes the above-mentioned preset shortcut applications and For other shortcut applications, the preset shortcut application is used as the main shortcut application, and other shortcut applications are used as secondary shortcut applications. The method of synchronizing the application list also includes:

Step S61, when an instruction to display the application list is detected from the shortcut application in the display terminal, extract the local blacklist of the main shortcut application at the current moment;

Step S62, if the current local blacklist of the main shortcut application is extracted, control the slave shortcut application to generate a corresponding application list according to the current local blacklist of the main shortcut application and display the application list on the display terminal.

After the local blacklist of the main shortcut application (such as the Launcher application of the display terminal system) is synchronized with the remote blacklist of the preset server, when the secondary shortcut application (such as the hotkey application of the display terminal system) in the display terminal detects When displaying the command of the application list, the slave shortcut application does not need to establish a network connection with the preset server. By extracting the current local blacklist of the main shortcut application, and after successfully extracting the current local blacklist of the main shortcut application, control the slave The shortcut application generates a corresponding application list according to the local blacklist of the master shortcut application at the current moment and displays the application list on the display terminal, which can keep the master shortcut application consistent with the application list displayed by the slave shortcut application, and can avoid the display terminal. The main shortcut application and the secondary shortcut application all submit a request to the preset server to download the remote blacklist when the application list needs to be displayed, thereby preventing the shortcut application in the display terminal from frequently initiating a network connection request to the preset server and reducing the impact on the display terminal. The occupation of system resources also avoids the problem of network congestion and high occupancy rate of the preset server due to being accessed by too many shortcut applications.

In addition, the setting of the main shortcut application and the secondary shortcut application can be set according to the frequency of the shortcut application being used by the user. The shortcut application with a higher frequency of use by the user is greater than the preset frequency value as the main shortcut application, and the higher the frequency of user usage is less than or equal to the preset value. Set the frequency value shortcut as the secondary shortcut.

Further, on the basis of the second embodiment of the application list synchronization method of the present invention, a third embodiment of the application list synchronization method is proposed. Referring to FIG. 3 , in the third embodiment, after step S61, it further includes:

Step S63, if the local blacklist of the main shortcut application at the current moment is not extracted, then extract and display the system blacklist pre-stored in the terminal;

Step S64, if the system blacklist pre-stored in the display terminal is extracted, control the shortcut application to generate a corresponding application list according to the system blacklist pre-stored in the display terminal and display the application list on the display terminal.

When the local blacklist at the current moment of the main shortcut application is not extracted from the shortcut application, for example, the main shortcut application has not displayed its application list to obtain the remote blacklist of the preset server, at this time, extract and display the system prestored in the terminal system blacklist. If the system blacklist pre-stored in the display terminal is extracted from the shortcut application, the system blacklist is saved from the shortcut application, and a corresponding application list is generated according to the system blacklist, and the generated application list is displayed on the display terminal show.

In this embodiment, after the local blacklist and the remote blacklist are not synchronized, or after the synchronization fails, when the display terminal detects an instruction to display the application list from the shortcut application, if the local blacklist of the main shortcut application is not extracted list, the system blacklist pre-stored in the display terminal is further extracted to prevent all applications installed on the display terminal from being displayed in the form of an application list due to the vacancy of the blacklist from the shortcut application, thereby avoiding policy risks to a certain extent; and, Since the policy change frequency of the application list is small, when the blacklist of the master shortcut application is not found on the preset server, the blacklist saved by the master shortcut application is also the system blacklist pre-stored in the display terminal, so that the master shortcut application and the slave shortcut application The blacklists are consistent, so the main shortcut application and the application list generated by the secondary shortcut application are also consistent, thereby ensuring the synchronization of the main shortcut application and the application list generated by the secondary shortcut application.

Further, on the basis of the third embodiment of the application list synchronization method of the present invention, after step S63, it also includes:

Step S65, if the system blacklist pre-stored in the display terminal is not extracted, then obtain the initial blacklist that comes with the shortcut application when it is installed;

Step S66, controlling to generate a corresponding application list from the shortcut application according to its own initial blacklist and displaying the application list on the display terminal.

When neither the current local blacklist of the main shortcut application nor the system blacklist pre-stored in the display terminal is extracted, that is, when errors occur in both the main shortcut application and the system blacklist pre-stored in the display terminal, further obtain the slave shortcut application The initial blacklist that comes with the installation, and controls the generation of the corresponding application list from the shortcut application according to the initial blacklist that comes with it and displays the application list on the display terminal to prevent all the shortcut applications from being displayed due to the vacancy of the blacklist The applications installed on the terminal are displayed in the form of an application list, thus avoiding policy risks to a certain extent.

The present invention also provides a display terminal, which can establish a network connection with a preset server. Referring to FIG. 4, in the first embodiment of the display terminal of the present invention, the display terminal includes:

The obtaining module 10 is used to obtain the latest version of the remote blacklist in the preset server when the shortcut application preset in the display terminal detects an instruction to display the application list;

A blacklist (that is, a blacklist configuration file) is preset in the preset server (that is, the remote server corresponding to the display terminal, and the server can provide data update services for the display terminal), and the blacklist in the server can be set according to national policies. The changes are updated in real time and can be downloaded and updated by the display terminal, so that after the display terminal leaves the factory, the server can still update the blacklist of the display terminal to ensure that the application list displayed by the display terminal complies with national policies and avoid policy risks.

After the display terminal is powered on and started, if the shortcut application preset in the display terminal detects the command to display the application list, for example, the Launcher (Android desktop launcher) application automatically receives the command to display the application list after the display terminal is started, and obtains the module 10 Obtain the latest version of the remote blacklist in the pre-configured server, that is, obtain the blacklist in the pre-configured server that is closest to the current national policy. Specifically, the display terminal detects from the server whether there is the latest version of the remote blacklist (here, the server will upload the latest version of the blacklist in time), that is, the background service of the display terminal uses a thread to connect to the preset server, detect Whether there is a remote blacklist in the server, and if it exists, the preset shortcut application in the display terminal will download the blacklist from the server, and store the blacklist in the application storage space corresponding to the preset shortcut application.

The comparison module 20 is used to compare the local blacklist corresponding to the shortcut application with the remote blacklist;

The first synchronization module 30 is configured to use the remote blacklist as a new local blacklist for the shortcut application when the local blacklist is inconsistent with the remote blacklist, and control the shortcut application to generate a corresponding application list according to its local blacklist and Display the application list on the display terminal.

Among them, it should be noted that the display terminal pre-stores a system blacklist in the corresponding location of the display terminal system directory (namely the system directory). Since the files in the system directory will not be cleared when the user restores the factory settings, if the server When something goes wrong and the preset shortcut application has not downloaded the remote blacklist from the server, and the local blacklist of the shortcut application itself cannot be extracted, the shortcut application can obtain the system blacklist from the system directory to use the system blacklist based on this system blacklist. The displayed application list is controlled to realize the synchronization of the application list. That is, at this time, the acquisition module 10 and the first synchronization module 30 also have other applications. Specifically, when the remote blacklist is not obtained, the obtaining module 10 first obtains its own local blacklist; 30 Control the shortcut application to generate a corresponding application list according to the obtained or extracted blacklist and display the application list on the display terminal.

The comparison module 20 compares the local blacklist stored in the application storage space of the preset shortcut application with the remote blacklist downloaded from the preset server, and when the local blacklist is inconsistent with the remote blacklist, it indicates If the blacklist is updated, the first synchronization module 30 uses the remote blacklist as the new local blacklist of the preset shortcut application. Generally, the remote blacklist is stored in the directory storage space of the preset shortcut application, and the directory The storage space needs to be adjusted by other applications, so open permissions are required for remote blacklist storage, and the MODE_WORLD_READABLE attribute is used for data storage.

Optionally, the first synchronization module 30 includes;

An acquisition unit 31, configured to acquire all applications installed on the display terminal to obtain a complete application set;

The first filtering unit 32 is configured to filter out invisible applications in the complete application set to obtain a primary application set;

The second filtering unit 33 is configured to control the shortcut application to filter out the blacklisted applications in the primary application set according to its local blacklist and generate a corresponding application list;

The display unit 34 is configured to display the generated application list on the display terminal.

There are many applications installed in the system of the display terminal, and the properties of some of the applications themselves are invisible. Therefore, when the preset shortcut application obtains the applications in the display terminal system, it first obtains all the applications installed on the display terminal to obtain the included Display the complete application collection of all applications on the terminal, and then need to add filter conditions, filter out the applications that do not need to be displayed through primary filtering, and obtain a primary application collection. Then the first synchronization module 30 controls the preset shortcut application to further filter the primary application set according to its current local blacklist, that is, to filter out the applications on the local blacklist from the primary application set, thereby obtaining an application set to be displayed, and The applications in the application set to be displayed are displayed on the display terminal in the form of an application list.

It should be noted that the constituent units included in the first synchronization module 30 are also included in the second synchronization module 62 and the third synchronization module, the difference is that the second filtering unit 33 is used to control the shortcut application according to its The acquired or extracted blacklist filters out blacklisted applications in the primary application set and generates a corresponding application list.

In addition, the first synchronization module 30 is also configured to keep the local blacklist of the shortcut application unchanged when the local blacklist is consistent with the remote blacklist.

When the local blacklist stored in the application storage space of the preset shortcut application is consistent with the remote blacklist downloaded from the preset server, it indicates that the remote blacklist on the server has not been updated relative to the local blacklist, and the local blacklist complies with the current According to the national policy, the first synchronization module 30 keeps the local blacklist of shortcut applications preset by the display terminal unchanged, and the preset shortcut applications use the free local blacklist to generate a corresponding application list.

In this embodiment, when the shortcut application preset in the display terminal detects an instruction to display the application list, the acquisition module 10 acquires the latest version of the remote blacklist in the preset server; then the comparison module 20 matches the shortcut application The local blacklist is compared with the remote blacklist; moreover, when the local blacklist is inconsistent with the remote blacklist, the first synchronization module 30 uses the remote blacklist as a new local blacklist for shortcut application; finally, the control shortcut The application generates a corresponding application list according to its local blacklist and displays the application list on the display terminal, so that the shortcut application preset in the display terminal can synchronize its local blacklist with the remote blacklist in time, so that the preset The local blacklist among shortcut applications is also synchronized, so that the application list displayed on the display terminal by the preset shortcut application is also synchronized, which solves the problem of inconsistency in the application list displayed on the display terminal by the shortcut application.

After the local blacklist of the main shortcut application (such as the Launcher application of the display terminal system) is synchronized with the remote blacklist of the preset server, when the secondary shortcut application (such as the hotkey application of the display terminal system) in the display terminal detects When displaying the instruction of the application list, there is no need to establish a network connection with the preset server from the shortcut application, and the local blacklist of the current moment of the main shortcut application is extracted through the file extraction module 61, and the local blacklist of the current moment of the main shortcut application is successfully extracted. Afterwards, the second synchronization module 62 controls the slave shortcut application to generate a corresponding application list according to the local blacklist of the master shortcut application at the current moment and displays the application list on the display terminal, thereby avoiding the display of the master shortcut application and the slave shortcut application in the terminal. All the applications request the preset server to download the remote blacklist when they need to display the application list, so as to avoid frequent network connection requests from the shortcut applications in the display terminal to the preset server, reduce the occupation of display terminal system resources, and avoid The pre-configured server has problems of network congestion and high occupancy due to being accessed by too many shortcut applications.

In addition, the setting of the main shortcut application and the secondary shortcut application can be set according to the frequency of the shortcut application being used by the user. The shortcut application with a higher frequency of use by the user is greater than the preset frequency value as the main shortcut application, and the higher the frequency of user usage is less than or equal to the preset value.
