The present invention relates to communications technologies, and in particular to a web application management method and apparatus.
Currently, a common intelligent terminal has a function of browsing a web page through a browser and is further capable of viewing a recently opened application list (recently opened app list), which facilitates a user to rapidly open a recently used application. For example, by double clicking the Home button on an iphone4, a user can open an icon list of recently opened applications and select an application recently used by the user from the list. A web page presented in a browser is a web application (Web Application, Web App for short). The Web App is compiled by using a Web development language, is capable of directly running in the browser in the form of a web page, and has many types, such as a game and news. For example, the game “Angry Birds” has a version of a Web App type.
However, the Web App has following problems in practical use: The Web App runs in a browser in the form of a web page and is used as a process of the browser instead of being used as a separate application; therefore, the Web App cannot be displayed in a recently opened application list; and if a user wants to switch back to a recently opened Web App in the form of a web page from another interface such as a desktop, the user only can first find the browser from the recently opened application list, open the browser, and then select a page corresponding to the Web App from multiple pages opened in the browser. In the foregoing manner, if the user wants to switch and return to the recently used Web App in the form of a web page, the user needs to execute many operation steps. As a result, switching back efficiency of the Web App is low.

A web application Web App is compiled by using a Web development language. The Web App includes an application running in a browser in the form of a web page and further includes an application that is developed by using the Web language and directly runs in an operating system in the form of widget. Embodiments of the present invention are aimed at an application running in the browser in the form of a web page.
101. Acquire a display mark of a web application opened in a browser, an identifier of the browser, and a uniform resource locator URL of the web application.
When a certain web page is opened in the browser, the browser is capable of acquiring description information corresponding to the web page, where the description information includes the uniform resource locator URL of the web application and so on, and the description information belongs to attribute information corresponding to the web page and is carried by the web page itself.
The identifier of the browser specifically refers to a parameter used to open the browser, for example, an installation path of the browser, such as an installation path of a Chrome browser, a UC browser, a TTGO browser, a QQ browser, or an Opera browser, or an identifier required for opening a corresponding browser.
In this embodiment, the display mark of the web application includes: a name of the web application and an identifier of the web application, where the identifier of the web application includes an icon or a screenshot of a running interface of the web application.
102. Receive a first instruction used to display a recently opened application list, and display the display mark of the web application in the recently opened application list according to the first instruction.
In the embodiment of the present invention, the display mark of the web application may be displayed in the recently opened application list so as to facilitate a user to identify the web application.
In a specific implementation, in order to enable the display mark of the web application to be displayed in the list when a user opens the “recently opened application list”, after acquiring information such as the URL and the display mark of the web application, the browser may store the information in an access file of a “recently opened application list” process. The access file refers to a system file to be accessed by the process when the “recently opened application list” process is activated (at this time, the user wants to view the recently opened application list).
When a terminal receives the first instruction used to display the recently opened application list, that is, an instruction for activating the “recently opened application list” process, the process accesses the access file, and the display mark of the web application may be displayed in the “recently opened application list”, that is, the displaying the display mark of the web application in the recently opened application list according to the first instruction is implemented. The display operation in the list may be executed by a function module responsible for list display in the terminal.
103. Receive a second instruction that a user selects the web application according to the recently opened application list, and open the web application corresponding to the URL according to the second instruction by using the browser corresponding to the identifier of the browser.
The operation may be executed by a function module responsible for activating an application in the terminal. After receiving the second instruction that the user selects a certain Web App from the recently opened application list, the function module may open the web application corresponding to the URL according to the second instruction by using the browser corresponding to the identifier of the browser, where the identifier of the browser is used to indicate that the Web App is opened through which browser, and the URL of the web application is used to open the Web App according to the URL. The user may select the web application, for example, by clicking the display mark of the Web App in the list.
In a specific implementation, the receiving second instruction that the user selects a certain Web App from the recently opened application list is may be, for example, detecting the second instruction of the user in a hardware manner, detecting the second instruction (that is, an operation of selecting the Web App) of the user in a software manner, detecting the second instruction of the user is in a combined manner of hardware and software, or the like. This is not limited in this embodiment of the present invention as long as the second instruction can be detected and the foregoing function module responsible for activating an application can be notified of the second instruction. Through the foregoing steps, the display mark of the web application is displayed in the “recently opened application list”, and the user directly activates the Web App by using the “recently opened application list”.
An actual application scenario is used as an example in the following to illustrate the effects after the method in this embodiment is adopted: It is assumed that the user opens a website, www.facebook.com by using a chrome browser on a smart phone to view activities of friends; then, the user opens a Web App in the chrome browser, for example, the “Angry Birds” to play; and later, the user wants to view stock information, and therefore opens a second Web app in the chrome browser, for example, the “Stock Quotations”. Now, the user has opened three pages in total in the browser, including two Web Apps. At this time, the user suddenly receives a short message, so that the user enters a short message interface to view information, and then, when the user wants to switch back to the Web App, such as the “Angry Birds” that has been just played, the user needs to execute the following operations:
In the prior art, the user needs to execute four steps in total: first step: press and hold a Home button to open the “recently opened application list”; second step: find the Chrome browser in the recently opened application list and click to open the browser; third step: click a multi-page button in the Chrome browser to enter a multi-page selection interface; and fourth step: click a page tag corresponding to the “Angry Birds” to open and continually play the game.
After the method in this embodiment is adopted, four operation steps of the user in the prior art are reduced to two steps. When the user expects to switch back to the Web App “Angry Birds” that has been just used, the user only needs to execute the following steps: first step: press and hold the Home button to open the “recently opened application list”; and second step: find and click an identifier of the Web App, such as an icon of the “Angry Birds” from the recently opened application list to open and continually play the game. It can be obviously seen that the operation steps of the user are reduced to a great extent, and the switching back efficiency, that is, the efficiency of returning to a recently used Web App from another interface of the Web App is improved.
According to the web application management method in this embodiment, by displaying a display mark of a web application in a recently opened application list, a user is capable of directly selecting the web application from the list and opening the web application through a browser; and compared with that a browser is first selected and opened and then the web application is opened in the browser in the prior art, operation steps of the user are reduced because the web application is directly activated from the recently opened application list, and the switching back efficiency of the web application is improved.
Specifically, as shown in
201: A terminal opens a new web page in a browser according to a user instruction.
For example, the user may input address information corresponding to a web page that the user wants to access in an address bar of the browser, and the browser is capable of opening a corresponding web page according to the address information input by the user.
202: The browser determines whether the newly opened web page is a Web App.
In this embodiment, the following two methods may be adopted to determine whether the web page is a Web App:
The first method is extending the HTML5 specification.
Specifically, a new attribute may be extended for a certain element which is developed based on the HTML5 specification and in a document corresponding to the Web App. The document is used to describe relevant information of the Web App, the certain element is, for example, a meta element thereof, and the new attribute is a web page type attribute used to identify a web page type, for example, a name of the attribute may be set as “page-type”.
An attribute value of the web page type attribute is a value of the page-type, may be set as “web app” or “common-page” (common web page), and may be set when the Web App is developed based on the HTML5 specification. If the value of the page-type is null, it is common-page by default.
Furthermore, another new attribute may be further extended for the foregoing meta element, for example, “app-category” used to indicate a specific classification of a web app. Attribute values of the attribute may be games, news, social, travel, weather, utilities, sports, office, and other types, and the attribute is valid only when the value of the page-type is “web app”. The advantage of setting the attribute is that the classification to which the Web App belongs may be clearer, which is advantageous to searching and automatic classification of the Web App, for example, a target Web App may be rapidly found according to the “app-category”, or the Web App is classified according to the “app-category”.
A specific example of information developed through the extended HTML5 specification is taken in the following:
In this manner, after opening a new web page, the browser may acquire an attribute value of a web page type attribute corresponding to the web page and determine that the web page is a Web App if the attribute value is an attribute value used to identify a web application. For example, if it is determined that the value of the “page-type” is “web app”, it indicates that the web page is a Web App, or if the value of the “page-type” is “common-page”, it is determined that the web page is a common web page. In addition to the foregoing determination manners, the following may be further included: A “web-app” attribute of a Boolean type is extended, of which a value is “true” or “false”. When the value is “true”, it indicates that the web page is a Web App; otherwise, it is a common web page.
A second method is using a private method relevant to the browser:
Specifically, the Chrome browser is taken as an example. For a part of Web Apps, if a user wants to use the Web App in the form of a web page through the browser, the user needs to download the Web App in advance and install it in the Chrome browser. A corresponding icon of the Web App is displayed in a start page in the Chrome browser after the installation, and the user may select the Web App from the start page and open it in the browser. For example, the user may download and install the Web App in a Chrome Web App Store. During the installation of the Web App, an installation file is generated, a suffix of the installation file generally is “*.crx”, and the installation file includes a “manifest.json” file used to describe information of the Web App.
In this embodiment, the browser may acquire relevant information of the Web App from the “manifest.json” file of the installation file of the Web App during the installation of the Web App, and specifically acquire a URL of the Web App. The browser may further establish a Web App URL list used to store a URL of each Web App. In this way, subsequently, when the user opens a Web App from the browser, because a Web App in the form of a web page is opened by accessing a URL, the browser may know a URL of the Web App and search for the foregoing Web App URL list to determine whether the URL is stored. If yes, it indicates that the web page is a Web App; otherwise, the web page is a common web page.
In the foregoing manner of acquiring the URL of the Web App, a specific web app installation manager generally exists in the browser and identifies whether a web app is to be installed. For example, a web app in the chrome browser is of an *.crx format, and a web app installation manager knows, through the *.crx format, that the program is a web app.
An example of an *.json file is taken in the following, and the browser may extract and store a “web_url” field thereof:
In this step, if the browser determines that the web page is a Web App, 203 is continually executed; otherwise, processing is executed according to a normal processing procedure of a common page in the prior art.
203: Acquire description information of a Web App and store the description information in an access file of a recently opened application list process.
The browser is capable of obtaining description information of a web page opened in it. The description information of the Web App may include: a display mark of the Web App, an identifier of a browser used to open the Web App, and a URL of the Web App.
A specific example of part of optional description information of the Web App is taken in the following:
The display mark of the Web App may be, for example, a name of the Web App, the foregoing Name: Angry Birds, and an icon of the Web App, that is, an image corresponding to the Icon: 16.png, or the name, a screenshot, and so on of the Web App. In this embodiment, for the screenshot of the Web App, it is set to be acquired in subsequent 206 and sent to the access file. The identifier of the browser is the foregoing Browser: Chrome; and the URL of the Web App is the foregoing http://chrome.angrybirds.com.
In this embodiment, a function module responsible for display in the terminal may further control the display mark of the Web App to be displayed in the recently opened application list when the recently opened application list process is executed. For example, the display mark of the Web App, such as the name and icon, is displayed in the list when the user opens the “recently opened application list”, so that subsequently the display mark of the Web App is in the list when the user opens the recently opened application list.
204: The terminal starts to activate the Web App according to a user instruction.
That is, the user starts to use the Web App.
205: The terminal closes the browser or exits an interface of the Web App according to a user instruction.
For example, the exiting an interface of the Web App is that, for example, the user returns to another interface (such as a desktop).
206: The browser takes a screenshot of a running interface of the Web App.
The browser takes the screenshot of the running interface of the current Web App because of triggering of a user action in 205 and sends the screenshot to the access file corresponding to the recently opened application list. The screenshot is also used as an identifier of the Web App. In addition, the terminal may also display the screenshot in the recently opened application list.
It should be noted that how the browser detects the action in 205 or how the action in 205 is transferred to and known by the browser is not strictly limited in this embodiment, and a conventional information transfer method in the form of hardware or software in the art may be adopted.
207: The terminal receives a first instruction that is used to display the recently opened application list and is input by the user.
A manner of inputting the first instruction by the user may be that, the user presses a function key that can activate the recently opened application list. For example, after finishing other work, such as viewing a short message, the user wants to return to the Web App “Angry Birds” again, the user may press a corresponding function key to activate the recently opened application list. For example, the user may press and hold the Home button, double click the Home button, click a certain specific key, or the like, and specifically, to press which key and how to press a key may be preset.
208: Display the recently opened application list, where the list includes the display mark of the Web App.
After the user presses a key, the “recently opened application list” is displayed on a screen of the terminal, and the list includes a display mark of the recently used Web App “Angry Birds”, where the display mark may be, for example, any one or any combination of an icon, a name, and a screenshot.
209: The terminal receives a second instruction that the user selects the Web App according to the recently opened application list.
For example, a manner of inputting the second instruction by the user may be that, the user clicks the display mark of the Web App in the recently opened application list.
210: The terminal opens the Web App corresponding to a URL according to the second instruction by using a browser corresponding to an identifier of the browser.
The terminal may search for, according to the second instruction input by the user in 209, that is, the display mark of the Web App selected by the user form the recently opened application list, the description information of the Web App corresponding to the display mark, and open the Web App corresponding to the URL according to the browser identifier, the URL of the Web App, and so on in the description information by using the browser corresponding to the identifier of the browser.
Specifically, for the method in this embodiment, reference may be made to
The method in this embodiment may further implement adding of an identifier of a recently opened Web App into the “recently opened application list”, so as to facilitate a user to directly activate the Web App from the list. Furthermore, in this manner, it is taken consideration that multiple opened web pages generally exist, and in order to avoid that the identifier of the Web App is swallowed up because of an excessive number of identifiers of web pages in the list, an upper limit of the number of identifiers may be set, for example, identifiers of only five recently opened web pages are displayed in the “recently opened application list”.
Furthermore, in this embodiment, a user interface (User Interface, UI for short) when the recently opened application list is opened may be further improved.
Referring to
The terminal may receive a third instruction that the user selects the browser according to the recently opened application list, for example, the user may click the display mark of the browser, and display the display mark of the web application according to the third instruction, that is, web page identifiers, such as a thumbnail view, an icon, or a web page name of a web page, of multiple web pages that have been just opened appear after the user clicks the display mark of the browser. At this time, the terminal receives a second instruction that the user selects the web application according to the display mark of the web application, that is, at this time, the user selects a corresponding web page identifier and clicks it, so as to open a corresponding web page.
In this manner, actually, the display mark of the browser is also displayed in the recently opened application list, and the display mark of the Web App is located in a subdirectory of the display mark of the browser. The advantages are as follows: In one aspect, when a great number of web pages exist in the list, the list is set in a subdirectory of the browser, which makes the list more concise and facilitates the user to search for a Web App that the user wants to use; and in another aspect, in this manner, although the user also needs to execute multiple operations, an operation of searching for and selecting the identifier of the Web App can be rapidly executed. Compared with that all pages in the browser must be opened (multi-page selection), and then a page where the Web App is located is selected from multiple pages in the prior art, in this embodiment, only the page where the Web App is located needs to be opened, which still improves the switching back efficiency of the Web App.
This embodiment provides a web application management apparatus. The web application management apparatus may be located in a terminal, and the apparatus includes, for example, a browser, a function module responsible for activating an application, a function module responsible for display control, and so on in the terminal. A combination of these function modules is called a web application management apparatus. The web application management apparatus may execute the web application management method in any embodiment of the present invention. When a user uses a terminal including the apparatus, the user can rapidly switched back to a recently used Web App from another interface.
