Receiving Notifications on Application List Changes

Learning to receive notifications when the list of installed applications changes allows you to manage all the device applications from your application:

1. Define the event handlers for different notifications using the ApplicationInformationEventCallback listener interface:

   var appEventCB = 
   { 
      /* When new applications are installed */
      oninstalled: function(application) 
      { 
         console.log("Application " + application.name + " installed"); 
      } 
   
      /* When applications are updated */
      onupdated: function(application) 
      { 
         console.log("Application " + application.name + " updated"); 
      } 
   
      /* When applications are uninstalled */
      onuninstalled: function(appid) 
      { 
         console.log("Application " + appid + " uninstalled"); 
      } 
   } 

2. Register the listener to use the defined event handlers:

   var listenerID = webapis.application.addAppInfoEventListener(appEventCB);

3. To stop the notifications, use the removeAppInfoEventListener() method of the ApplicationManager interface:

   webapis.application.removeAppInfoEventListener(listenerID);
