Description

  The present invention relates to an application management apparatus, an application management method, and a computer-readable recording medium that records a program for realizing the application management apparatus that manages an application program executed on a mobile terminal.

  In recent years, attention has been focused on HTML5 in the field of networks (for example, see Patent Documents 1 and 2). HTML5 is the fifth edition of HTML, which is a markup language for describing Web pages, and new specifications not added to conventional HTML are added.

  Specifically, in HTML5, an audio tag for embedding audio, a video tag for embedding a moving image, and a canvas tag that enables drawing of graphics are added.

  Further, in addition to the above, an offline Web application function is added to HTML5. The offline web application is a web application program that can be used continuously regardless of the network state, and operates using resources stored on the terminal side.

  According to the offline web application function, the user can use the web application by a terminal in an offline state. Due to such characteristics, further spread of HTML5 is particularly desired in smartphones whose use is rapidly increasing.

(Embodiment)
Hereinafter, an application management apparatus, an application management method, and a program according to an embodiment of the present invention will be described with reference to FIGS.

[Device configuration]
First, the configuration of the application management apparatus according to the present embodiment will be described with reference to FIG. FIG. 1 is a block diagram showing a configuration of an application management apparatus according to the embodiment of the present invention.

  An application management apparatus 10 according to the present embodiment illustrated in FIG. 1 is an apparatus that manages an offline Web application used in the communication terminal 30. In the present embodiment, the application management apparatus 10 is constructed on the OS (Operating System) of the communication terminal 30 by a program described later. Specific examples of the communication terminal 30 include a mobile phone, a smartphone, and a tablet-type information device that can execute an application program.

  As shown in FIG. 1, the application management apparatus 10 includes a Web application execution unit 11, a resource storage unit 12, and a resource management unit 13. Among these, the web application execution unit 11 acquires an offline web application resource from the web server 40 and executes the offline web application using the acquired resource.

  Here, the “offline web application” refers to an application program that can be executed in an offline environment by the offline web application function of HTML5. Further, the Web server 40 holds offline Web application resources as Web data 41.

  The resource storage unit 12 stores the resource acquired by the web application execution unit 11. The resource storage unit 12 is also referred to as “offline Web application cache” 12. The resource management unit 13 manages resources stored in the resource storage unit 12.

  Thus, in the present embodiment, all the resources of the offline web application acquired from the web server 40 are stored in the resource storage unit 12 by the web application execution unit 11. Further, the resources of the offline Web application stored in the resource storage unit 12 are centrally managed by the resource management unit 13.

  For this reason, if a restriction such as a password is set for access to the application management apparatus 10, even if the communication terminal 30 is in the hands of a third party, it is included in the information (resource) cached when using the offline Web application. The situation where important information is leaked is avoided.

  Here, the configuration of the application management apparatus 10 in the present embodiment will be described more specifically.

  In the present embodiment, the web application execution unit 11 includes a web browser 16, and accesses the web server 40 using the web browser 16. Further, when acquiring the resource of the offline Web application, the Web application execution unit 11 first acquires a manifest file from the Web server 40 and acquires the resource according to the manifest file.

  As shown in FIG. 1, the application management apparatus 10 further includes a data storage unit 14 and a data synchronization unit 15. The data storage unit 14 is a database called SQLite, for example, and stores data created or used by an offline Web application.

  The data synchronization unit 15 determines whether data corresponding to the data stored in the data storage unit 14 is updated in the Web server 40 in the Web server 40. If the result of the determination is that the data has been updated, the data synchronization unit 15 updates the data stored in the data storage unit 14. In the Web server 40, the data is held as business data 42.

  In this embodiment, when the deletion of the offline Web application is instructed, the resource management unit 13 first deletes the resource of the offline Web application instructed to delete from the resource storage unit 12. Further, the resource management unit 13 deletes the data created or used by the offline web application instructed to be deleted from the data storage unit 14.

[Device operation]
Next, the operation of the application management apparatus 10 according to the first embodiment of the present invention will be described with reference to FIGS. In the present embodiment, the application management method is implemented by operating the application management apparatus 10. Therefore, the description of the application management method in the present embodiment is replaced with the following description of the operation of the application management apparatus 10.

[Register offline Web application]
First, an operation when registering an offline Web application in the application management apparatus 10 will be described. FIG. 2 is a flowchart showing the operation of the application management apparatus shown in FIG. 1 when registering an offline Web application.

  As shown in FIG. 2, first, the web application execution unit 11 accesses the URL of the web server 40 that provides the offline web application in accordance with an instruction from the user of the communication terminal 30 (step A1).

  Next, the web application execution unit 11 activates the web browser 16 (step A2), and causes the web browser 16 to access an HTML file prepared by the web server 40.

  Next, the web application execution unit 11 causes the web browser 16 to acquire offline web application resources from the web server 40 (step A3). Further, the Web application execution unit 11 stores the acquired resource in the resource storage unit 12 and notifies the resource management unit 13 of this.

  Further, the web application execution unit 11 stores data used in the offline web application from which the resource is acquired in the data storage unit 14. When the web server 40 designates a manifest file for the offline web application, in step A3, the web browser 16 obtains the designated manifest file and obtains resources according to the manifest file.

  Next, the resource management unit 13 manages the resource stored in the resource storage unit 12 as a management target (step A4). Specifically, the resource management unit 13 records information related to the acquired resource, such as an application name, an acquisition date and time, an expiration date, and a size, in a management file (not shown).

  As described above, a new offline Web application is managed by the application management apparatus 10 by executing steps A1 to A4.

[Use of offline web application]
Next, an operation when using the offline Web application in the application management 10 will be described. FIG. 3 is a flowchart showing the operation of the application management apparatus shown in FIG. 1 when using the offline Web application.

  As shown in FIG. 3, first, the web application execution unit 11 starts the web browser 16 when the user of the communication terminal 30 instructs execution of an offline web application (step B1).

  Next, the web application execution unit 11 causes the web browser 16 to access the resource storage unit 12 and read the resource of the specified offline web application (step B2).

  Next, the web application execution unit 11 causes the web browser 16 to execute an offline web application (step B3). For example, if an offline Web application from which resources have been read is an application program that enables online at a specific site, the user can perform shopping using this application program.

  Next, the Web application execution unit 11 determines whether the user has not instructed termination (step B4). If termination is instructed as a result of the determination in step B4, the web application execution unit 11 terminates the offline web application being executed.

  On the other hand, as a result of the determination in step B4, if termination is not instructed, the web application execution unit 11 determines whether access to the web server 40 is necessary (step B5).

  Specifically, as described above, when the offline Web application is an application program that enables online shopping at a specific site, products that can be purchased at the specific site are updated and can be purchased. Product data needs to be updated. Therefore, the Web application execution unit 11 determines that access is necessary when the offline Web application being executed is an application program that requires such an update.

  If access is not necessary as a result of step B5, the web application execution unit 11 executes step B3 again. On the other hand, if access is necessary as a result of step B5, step B6 is executed.

  In step B <b> 6, the data synchronization unit 15 determines whether data corresponding to the data stored in the data storage unit 14 is updated in the Web server 40 in the Web server 40. If the result of determination in step B6 has not been updated, data synchronization is not necessary, so step B3 is executed again.

  On the other hand, if it is updated as a result of the determination in step B <b> 6, the data synchronization unit 15 acquires the updated data from the business data 42 of the Web server 40, and uses this data in the data storage unit 14. The stored data is updated (step B7).

  For example, in the case of the above-described application program for online shopping, data of commodities that can be purchased is updated. The data synchronization unit 15 can also instruct the Web server 40 to update when the data on the application management apparatus 10 side is newer than the business data 42 of the Web server 40.

  As described above, the execution of steps B1 to B7 allows the user to use the offline Web application. Steps B1 to B7 are repeatedly executed until the user instructs the end.

[Delete offline Web application]
Next, an operation when deleting an offline Web application from the application management 10 will be described. FIG. 4 is a flowchart showing the operation of the application management apparatus shown in FIG. 1 when deleting the offline Web application.

  First, as shown in FIG. 4, the resource related unit 13 receives an instruction to delete a specific offline Web application from the user of the communication terminal 30 (step C1).

  Next, the resource management unit 13 accesses the resource storage unit 12, identifies the resource of the instructed offline Web application, and deletes it (step C2). At this time, if there is a manifest file for the offline Web application instructed to be deleted, the resource management unit 13 deletes the resource according to the manifest file.

  Next, the resource management unit 13 accesses the data storage unit 14, specifies data to be created or used in the designated offline Web application, and deletes the specified data (step C3). Also at this time, if there is a manifest file, the resource management unit 13 deletes the data according to the manifest file.

  As described above, the execution of steps C1 to C3 allows the user to reliably delete the offline Web application that the user desires to delete. The user can also specify two or more offline Web applications that are desired to be deleted. In this case, two or more offline Web applications are deleted at a time.

  As described above, in the present embodiment, the offline Web application is centrally managed. In addition, since update of data is also managed in an integrated manner, all offline Web applications can be easily updated. Furthermore, it is possible to reliably delete an offline Web application that is desired to be deleted.
