Overview

This code snippet demonstrates how to use the AppManager Service API to discover the applications that are installed on the device.

</html>

Source: script.js

var serviceObj = null;
 
window.onload = init;
 
// Initializes the widget
function init() {
// Obtain the AppManager service object
try {
serviceObj = device.getServiceObject("Service.AppManager", "IAppManager");
} catch (ex) {
alert("Service object cannot be found.");
return;
}
 
// We are interested in applications, so let's define the criteria
// respectively
var criteria = new Object();
criteria.Type = "Application";
 
// Obtain the list of installed applications
var result = serviceObj.IAppManager.GetList(criteria);
var appList = createAppList(result.ReturnValue);
appList.sort();
displayList(appList);
}
 
// Creates the list of installed applications
function createAppList(iterator) {
var list = new Array();
try {
iterator.reset();
var item;
while ((item = iterator.getNext()) != undefined) {
var txt = "";
txt += item.Caption + " (";
txt += item.Uid + ")";
list.push(txt);
}
} catch (ex) {
alert(ex);
}
return list;
}
 
// Displays a list on the screen
function displayList(list) {
var listElement = document.createElement("ol");
for (var i = 0; i < list.length; i++) {
var listItemElement = document.createElement("li");
var textElement = document.createTextNode(list[i]);
listItemElement.appendChild(textElement);
listElement.appendChild(listItemElement);
}
var bodyContentElement = document.getElementById("bodyContent");
bodyContentElement.appendChild(listElement);
}

Postconditions

The example displays an alphabetically ordered list of installed applications and their UIDs on an HTML page.
