Referring to FIG. 1, it is a schematic flow chart of a method for realizing downloading of mobile terminal application program according to one preferred embodiment of the present invention. In FIG. 1, the method for realizing downloading of mobile terminal application includes the following steps.
In step S110, a plug-in control unit (widget) is added on an operation interface of the mobile terminal, the plug-in control unit is displayed on the operation interface, and the plug-in control unit is used to realize the downloading of an application program.
In step S110, the plug-in control unit is displayed by way of the formats “xml”, “html” and “css”, and the user interface (UI) format “js” serves as a script which is a plug-in module with application description technique.
In one embodiment, the plug-in control unit is a small application program picture which is embedded in the various application programs, such as the desktop program of android mobile operating system, and periodically receives the update of the application program. A plug-in control unit for realizing the downloading of mobile terminal application program is added on an operation interface of the mobile terminal by employing the plug-in control technique. Further, the plug-in control technique controls the plug-in control unit to be displayed on the operation interface, so that the plug-in control unit controls the downloading procedure of the various application programs for the mobile terminal. In this case, the plug-in control unit is embedded in the launcher of the desktop program in the mobile terminal and the plug-in control unit is displayed on the operation interface. In other words, the plug-in control unit is displayed on the top layer of the operation interface. When the user operates the mobile terminal and enters the different operation interfaces, the plug-in control unit is displayed on the top layer of the current operation interface.
The plug-in control unit for realizing the downloading of mobile terminal application program is a small application program picture which is embedded in the launcher of the desktop program in the android mobile operating system.
In step S120, a plurality of downloading icons of the application program are arranged and displayed on the plug-in control unit, wherein the plurality of downloading icons of the application program are pushed by a background server to be obtained and each of downloading icons in the application programs is linked to a downloading address.
The plurality of downloading icons of the application program pushed by a background server to be obtained are arranged and displayed on the plug-in control unit of the mobile terminal so that the user is capable of selecting the downloading icons for downloading and installing the desired application programs. As shown in FIG. 4, the downloading icons of the application programs displayed on the plug-in control unit in the mobile terminal includes: WeChat, Weibo, Tudou, Thunder, GFAN, Xiami and QQ (an instant message software provided by Tencent), so that the user is capable of selecting the downloading icons for downloading and installing the desired application programs. Before the application program is downloaded completely, each of downloading icons corresponding to the application programs is linked to a downloading address.
To provide the downloading environment of the application program with the safety, speed and reliability, the mobile terminal further implement the following steps before the plurality of downloading icons of the application program pushed by the background server to be obtained are displayed on the plug-in control unit of the mobile terminal by way of hyperlinks. In other words, the step S120 further comprises the following steps S210, S220, S230, S240 and S250.
In step S210, the background server receives and stores the application programs, which are verified by a third party program.
To recommend the application programs with full function and performance stability for the user, the background server corresponding to the mobile terminal selects the received the third party program and stores the application programs with higher rating for the user access.
In step S220, the background server periodically pushes the stored application programs to the mobile terminals.
The background server periodically pushes the stored third party programs to the mobile terminals respectively. The mobile terminals display the application program icons on the plug-in control unit to be selected by the user. For example, the periodical push time may be set as once a week, longer periods of time or shorter periods of time based on the user's requirement. Certainly, the user is capable of controlling the mobile terminal to select one kind or some kinds of application programs to be periodically pushed on the plug-in control unit for the user.
In the step S230, a plurality of downloading icons of the application programs are arranged and displayed on the plug-in control unit, wherein the plurality of downloading icons of the application programs are pushed by a background server to be obtained and each of downloading icons in the application programs is linked to a downloading address.
The mobile terminal arranges and displays a plurality of downloading icons of the application programs, which are pushed by a background server to be obtained, on the plug-in control unit. As shown in FIG. 4, the user controls the mobile terminal to arrange the downloading icons based on the storing time of the application program in the mobile terminal or based on the occupied volume of the application programs. Meanwhile, the user may slide the touch panel of the mobile terminal to view the application program icons in the next page. Each of downloading icons of the application program on the plug-in control unit is linked to a downloading address correspondingly.
In the step S240, the plug-in control unit receives the update of the application program from the background server at a predetermined interval.
Since the update of application programs is quick, the plug-in control unit receives the update of the application program, i.e. up-to-date application program, for download at a predetermined interval from the background server, so that the user can access the latest and full-fledged application program. Based on the user's requirement, the predetermined interval is set to one week or shorter periods of time. Further, the user controls the mobile terminal to manually refresh the update status of the application program. The user may also find whether the update application programs exist on the plug-in control unit and determines whether to update the application programs.
While the application program is recommended to the plug-in control unit and the user clicks the update button, the server is checked to determine whether a new application program list exist in the server. If no, it prompts that the current application program list is a latest one and there is no need to update. If yes, the plug-in control unit downloads the new application program list, downloads the related data and images based on the content of the new application program list, and updates the picture of the plug-in control unit asynchronously.
In step S250, while each application program is downloaded and installed, the downloading icons corresponding to the application programs are set as a color indication. When the color indication of the downloading icon is clicked by the user, the application program is activated.
In this embodiment, the mobile terminal receives the user's instruction to issue a request to download the application program list by way of automatic update or manual update.
Based on user information corresponding to different application program lists, various mobile terminals acquires different application program list to satisfy the requirement of various terminal models mapping to different recommendation of the application program list.
To ensure that the user's mobile terminal identify which application programs are downloaded and installed completely, which application programs are not downloaded, and which application programs are downloaded but not installed, the downloading icons corresponding to the application programs are set to a color indication while each application program is downloaded and installed in the plug-in control unit of the mobile terminal. Specifically, the downloading icons corresponding to the application programs are set to a gray color indication before downloading and installing, and the downloading icons corresponding to the application programs are set to a color indication after downloading and installing completely. When the color indication of the downloading icons is clicked by the user, the application programs are activated.
Proceed to step S130 after the step S120 is complete.
In the step S130, an operational instruction of a user is received by way of the downloading icons of the application programs. Based on the operational instruction, the application programs corresponding to the downloading icons are downloaded, and the downloading statuses of the application programs on the plug-in control unit are identified.
The mobile terminal selects the desired application program for download according to the downloading icons of the application programs on the plug-in control unit, downloads the desired application program by clicking the downloading icon of the application program, and displays the downloading status of the application program in real-time to show the corresponding indication. As shown in FIG. 4, application program WeChat is downloaded and installed, application program Weibo is downloading, the downloading status of application program Tudou suspends, application program Thunder is downloaded and installed, application program GFAN is recommended to the user but is not downloaded, and application program Xiami is downloaded and installed.
Specifically, after the mobile terminal shows the corresponding indication, the following steps are implemented in FIG. 3.
In step S310, if the application program is not installed, the downloading icons of the application programs are set to a gray color indication and the “without installed” statuses of the application programs are further identified wherein the “without installed” statuses includes a “without download” status, a “partially downloading status but suspended” status, and a “complete downloaded without installation” status. As shown in FIG. 4, the indication “download” in the top left corner of the application program icon is in the “without downloaded” status.
Based on the step S250, while some application programs are not installed successfully, the mobile terminal controls the downloading icons corresponding to the application programs to be a gray color indication, and the downloading icons corresponding to the application programs indicate that the application programs are in “without installed” statuses, wherein the “without installed” statuses includes a “without downloaded” status, a “partially downloading status but suspended” status, and a “complete downloaded without installed” status. As shown in FIG. 4, the indication “download” in the top left corner of the application program icon WeChat is in the “without installed” status. As shown in FIG. 4, the indication “install” in the top left corner of the application program icon, e.g. application programs Thunder and Xiami, is in the “complete downloaded but not installed” status. As shown in FIG. 4, the indications “downloading” and “partially downloading status but suspended” in the top left corner of the application program icon, e.g. application programs Weibo and Tudou, are in the “downloading” status to show the downloading rate of the progress. As shown in FIG. 4, no indication in the top left corner of the application program icon, e.g. application programs GFAN and QQ, is in the “downloaded and installed” status.
Specifically, when it is normally in a download status, the top left corner of the plug-in control unit is changed to a downloading status to start downloading; otherwise, it will be prompted by unavailable causes, e.g. network implication or storing problem. If the download status pauses, the top left corner of the application program icon is changed to a pause status.
If the application program is downloaded and installed, the status of the top left corner of the application program icon hides and the application program icon is bright, i.e. without gray color indication.
In step S320, an operational instruction of a user is received by way of the downloading icons of the application programs. Based on the operational instruction, the application programs corresponding to the downloading icons are downloaded.
The user clicks the downloading icon of the application program on the plug-in control unit to activate the downloading instruction corresponding to the application program, and the mobile terminal downloads the application program based on the downloading instruction.
In step S330, if the application programs corresponding to the downloading icons are downloaded and installed, the downloading icons of the application programs are changed to a color indication and the color indication represents application program to be installed completely.
When the downloaded application program clicked by user is installed completely, the downloading icon of the application program is changed to a color indication based on the step S250 to prompt the user the complete installation of the application program.
In step S340, when the downloading icon of the application program with color indication receives the click operation of the user, the application program corresponding to the downloading icon is activated to start the implement of the application program.
When the application program is installed, the top left corner of the application program has no indication and the downloading icon is changed from gray color indication to color indication. Thus, the user can click the downloading icon of the application program to activate the application program for executing the application program conveniently.
The theorems and embodiments which the plug-in control unit implements the downloading manner are described below in detail.
Firstly, data persistence is described. When the plug-in control unit implements the downloading procedure of the application program, there is a need to control the various downloading statuses. For example, the downloading statuses includes a series of logic control statuses, e.g. downloading duration, a network interruption, system rebooting during a downloading process, a pause status, a complete download status, without installed status, and complete installed status. Since the variables of logic determination are recycled aperiodically, it is required to retain the status data when the plug-in control unit implements the downloading of the application program as if the accelerated parallel processing (APP) performs the downloading of the application program in the general store. In this case, the function of “SharedPreferences” is used to implement the data persistence wherein “SharedPreferences” is a lightweight storing class in the Android operating system platform for retaining the common arrangement, e.g. window statuses. The codes of the implement are described below:













 
 /**



  * determining whether to downloading the complete 



   status of “APK”



  * @param context



  * @param statu



  * @param packageName



  */



 public void setApkStatu(Context context,int statu,



 String packageName){











   SharedPreferences
uiState
=









context.getSharedPreferences(′′ApkStatu′′, 



Activity.MODE_PRIVATE);



   SharedPreferences.Editor editor = uiState.edit( );



   // adding value



   editor.putInt(packageName, statu);



   editor.commit( );



 }









Secondly, the data associated with the plug-in control unit cannot be cancelled by user to avoid the data failure. In thus embodiment, the plug-in control unit for implementing the download of application program in the mobile terminal is cable of clearing the data by way of the arrangement in the Android operating system as if the general application program performs the clearing procedure. After the data are cleared, the application program returns back the initial installation status and the data base of the application program and related documents are cancelled. The cancellation difference between the plug-in control unit for implementing the download of application program in the mobile terminal and general application program is that:
After the data associated with the application program are cleared, the life cycle of the data is over. When the user switches back to implement the application program, the application program is activated in an initial status.
However, in the present invention, the plug-in control unit in form of a picture is formed on the desktop program, the data of the application program interface are not actively refreshed. After the data are cleared, however, the picture of the plug-in control on the desktop viewed by the user is a picture with the data. While the user operates the plug-in control unit, there is no data to be operated, which results in failure control. Therefore, it is required to determine whether the data exist during the operation of the plug-in control unit. The codes of the implement are described below:













 
  if(intent==null){



   return;



  }










  context
=









AppWidgetApplication.getInstance( ).getApplicationContext( ):



  title_name = intent.getStringExtra(Constant.APP_NAME);



 view_postion = intent.getIntExtra(Constant.VIEW_POSITION,0);



 package_name = intent.getStringExtra(Constant.PACKAGE_NAME);










 activity_sart_name
=









intent.getStringExtra(Constant.ACTIVITY_START_NAME);



 apk_url = intent.getStringExtra(Constant.APK_URL);



   statuSharePreferense = new StatuSharePreferense( );



   if(!statuSharePreferense.getRunStatu(context)){



    Toast.makeText(this, ′′the data in the memory is cleared



and the application program list is refreshed to load the data again′′,



Toast.LENGTH_LONG).show( );



    DataView.getInstance( ).refresh(this);



    return;



  }









The data existence of the plug-in control unit is confirmed by determining whether the related documents exist in the plug-in control unit or not. After the data in the plug-in control unit are cleared, the application program interface is refreshed so that the picture of the plug-in control unit is the same as the data in the background server synchronously.
Thirdly, the plug-in control unit implements the user interface (UI) interaction of the downloading operation of application program.
In this embodiment, the plug-in control unit is utilized according to the “RemoteViews” so that the plug-in control unit implements the interaction of the downloading operation of application program. It is necessary to enrich the interface of the application program by way of an extending manner. In this embodiment, an activity window is activated by the plug-in control unit to serve as a dialog frame for the extending manner.
Generally, the activity window is a full-screen and it is activated to be found in the task stacks of the Android operating system. In one embodiment, the plug-in control unit serves as a component of the window and is placed on the desktop program wherein the component is not an individual module and does not activated in the activity window stacks.
Thus, it is necessary to process the activity window with the dialog frame so that the activity window looks like a dialog frame component generated by the plug-in control unit.
The activity window is defined as a dialog frame, which is a format with non-full screen, no title, dim background and semi-transparent frame. The codes of the implement are described below:













 
  <style name=′′downloadDialog′′ parent=′′@android:style/



  Theme.Dialog′′>



  <item name=′′android:windowFrame′′>@null</item>// set the 



  frame



  <item name=′′android:backgroundDimEnabled′′>true</item>// 



  enable or



 disable the dim background



  <item name=′′android:windowIsTranslucent′′>true</item>//set to 



be semi-transparent



  <item name=′′android:windowNoTitle′′>true</item>//set to 



  be no title



  <item name=′′android:windowFullscreen′′>false</item>//set to 



be the full screen if the dialog frame is false



  <item name=′′android:width′′>310dip</item>//set the width



  </style>









When the activity window is set completely, it is required to do the following procedure to form an activity window without task stacks and history records therein when announcing the activity window if the activity window occurs in the recent task stacks.












 <activity android:name=′′.DownloadDialogActivity′′


android:configChanges=′′orientation|keyboardHidden|navigation′′


  android:noHistory=′′true′′


  android:finishOnTaskLaunch=′′true′′


  android:launchMode=′′singleTop′′


  android:excludeFromRecents=′′true′′


  android:label=′′downloading ′′


  android:screenOrientation=′′portrait′′


  android:theme=′′@style/downloadDialog′′>


 </activity>









After completing the setting, the active window serves as a component of the pop-up dialog of the plug-in control unit, as show in FIG. 4.
Further, a searching item is set in the plug-in control unit to allow the user to search other application programs. This manner allows the user to find desired application program in the plug-in control unit.
