Service API</h1><div>
<p>The <a href="GUID-CF55DBA3-2D4C-4FD0-8A06-862E6128F4E7.html#GUID-CF55DBA3-2D4C-4FD0-8A06-862E6128F4E7">Logging 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 Logging Service API allows <span>widgets</span> to add, read, and
delete logging events such as call logs, messaging logs, and so forth. 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-CF55DBA3-2D4C-4FD0-8A06-862E6128F4E7.html#GUID-CF55DBA3-2D4C-4FD0-8A06-862E6128F4E7">Accessing device logs</a>.</p>
<div><h3>Using the Logging Service API</h3>
<p>To use the Logging 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.Logging</code> to identify the service provider
and <code>IDataSource</code> to identify the supported interface:</p>
<pre class="codeblock" id="GUID-0581BEE4-05E3-4D5A-9537-EB9CA4F58EE0-GENIDd0e51464">var so = device.getServiceObject("Service.Logging", "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-F146B956-77AE-41B5-BA17-20F48AF8DBA7.html#GUID-F146B956-77AE-41B5-BA17-20F48AF8DBA7"><code>IDataSource.Add()</code></a></p>
</li>
