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

Source: widget.xhtml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
<html xmlns="http://www.w3.org/1999/xhtml">
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/>
<script type="text/javascript" src="script.js" />
<title>WRT Application</title>
<div id="bodyContent" class="bodyContent">

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",
} catch (ex) {
alert("Service object cannot be found.");
// 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);
// Creates the list of installed applications
function createAppList(iterator) {
var list = new Array();
try {
var item;
while ((item = iterator.getNext()) != undefined) {
var txt = "";
txt += item.Caption + " (";
txt += item.Uid + ")";
} catch (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]);
var bodyContentElement = document.getElementById("bodyContent");


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