<p><strong>Return value:</strong></p>
<p>If the call succeeds, the <code>getServiceObject</code> method
returns a service object; otherwise it returns <code>undefined</code>.</p>
<p><strong>Remarks:</strong></p>
<ul>
<li><p>The <code>getServiceObject</code> method is a factory
method found on the <code>device</code> object.</p></li>
<li><p>To ensure backward compatibility, always check in your JavaScript
code that the <code>device</code> object exists before calling the <code>getServiceObject</code> method.
For example:</p>

<pre class="codeblock" id="GUID-B43A804D-CBB6-44E4-9514-E1982EA50507">if (device != "undefined")
  device.getServiceObject("Service.MediaManagement", "IDataSource");
</pre>

</li>
</ul>
<p><strong>Example code:</strong></p>
<p>The following example creates a service object for the <a href="GUID-E5684FF0-28C9-4721-9421-6B9432087086.html#GUID-E5684FF0-28C9-4721-9421-6B9432087086">Media
Management Service API</a>:</p>
<pre class="codeblock" id="GUID-00E9306D-0D8D-44DC-BA87-899BB4F9B000">var so = device.getServiceObject("Service.MediaManagement", "IDataSource");</pre>
