appId attribute can be used to launch an application with it's application Id.

appControl attribute can be used to launch an application control operation.

Sample app launch using appId with notification code snippet:

var myappId = tizen.application.getAppInfo().id;    // The app posting the notification 
var otherAppId = "org.tizen.clocksetting ";        //'settings' appId for example

var notificationDict =
   {
      content: "Notification App Launch",
      vibration: true,
      appId: myappId             // or otherAppId
   };

var notification = new tizen.StatusNotification("SIMPLE", "Simple notification", notificationDict);
tizen.notification.post(notification);
