several Android application debugging and analysis tools. The Monitor tool does not
require installation of a integrated development environment, such as Eclipse, and encapsulates the
following tools:</p>

<ul>
  <li><a href="{@docRoot}tools/debugging/ddms.html">DDMS</a></li>
  <li><a href="gltracer.html">Tracer for OpenGL ES</a></li>

</ul>


<h2 id="usage">Usage</h2>

<p>To start Device Monitor, enter the following command from the SDK <code>tools/</code>
directory:</p>
  <pre>monitor</pre>

<p>Start an Android emulator or connect an Android device via USB cable, and connect Device
Monitor to the device by selecting it in the <strong>Devices</strong> window.</p>

<p class="note"><strong>Note:</strong> Only one debugger can be connected to your device at a time.
If you're using ADT, you may need to close the debugging tool before launching the Device Monitor
in order for the device to be fully debuggable.</p>
