<p>The <a href="GUID-E3D26890-581A-427F-8AFF-16081528A8B8.html#GUID-E3D26890-581A-427F-8AFF-16081528A8B8">Media Management
Service</a> API is supported since <a href="GUID-1A3ECAC1-3F09-4602-A1CD-82164040A664.html#GUID-1A3ECAC1-3F09-4602-A1CD-82164040A664">WRT 1.1</a>.</p>
<p>The Media Management Service API allows <span>widgets</span> to retrieve information
(metadata) about the media files stored in the Media Gallery of a device.
The API is integrated into <span>WRT</span> through the <a href="GUID-571AF37F-1E95-462A-92D2-FEA2E62F1559.html#GUID-571AF37F-1E95-462A-92D2-FEA2E62F1559"><code>device</code></a> object.</p>
<p>For an overview of the service and the API, see section <a href="GUID-E3D26890-581A-427F-8AFF-16081528A8B8.html#GUID-E3D26890-581A-427F-8AFF-16081528A8B8">Accessing information about media files stored on a device</a>.</p>
<div><h3>Using the Media Management Service API</h3>
<p>To use the Media Management Service API, your <span>widget</span>  must first create <span>a service object for it
using the <a href="GUID-04095E9A-50E7-4E5F-BD6F-71DA281A0080.html#GUID-04095E9A-50E7-4E5F-BD6F-71DA281A0080"><code>device.getServiceObject()</code></a> method</span>.
Use <code>Service.MediaManagement</code> to identify the service provider
and <code>IDataSource</code> to identify the supported interface:</p>
<pre class="codeblock" id="GUID-E2C5C349-0E25-4508-A09C-78065249F25D-GENIDd0e56266">var so = device.getServiceObject("Service.MediaManagement", "IDataSource");</pre>

<p>This service object can then be used to access the services provided
by the API:</p>
<ul>
<li><p><a href="GUID-39C0BA48-E615-41B1-84FF-D4D0C4597DAB.html#GUID-39C0BA48-E615-41B1-84FF-D4D0C4597DAB"><code>IDataSource.GetList()</code></a></p>
</li>
<li><p><a href="GUID-4EBD83E1-B179-4F8B-93AB-4D58C5F749C3.html#GUID-4EBD83E1-B179-4F8B-93AB-4D58C5F749C3"><code>IDataSource.Cancel()</code></a></p>
</li>
</ul>
</div>
<div><h3>Emulator support</h3>
<p>The S60 5th Edition SDK emulator provides full support for the Media
Management Service API.</p>
<p>Retrieving media file information from a memory card is only possible
on a physical device. In the emulator, drive E: simulates the memory card
installed on a physical device.</p>
