-<p>Provides classes to manage Low-power Wireless Personal Area Network (LoWPAN) functionality on the device.
-Examples of such network technologies include <a href="http://threadgroup.org/">Thread</a> and
-<a href="http://www.zigbee.org/zigbee-for-developers/network-specifications/zigbeeip/">ZigBee IP</a>.</p>
-<p>The LoWPAN APIs provide a means by which applications can communicate
-with the lower-level wireless stack that provides LoWPAN network access.</p>
-
-<p>Some APIs may require the following user permissions:</p>

- <li>{@link android.Manifest.permission#ACCESS_LOWPAN_STATE}</li>
- <li>{@link android.Manifest.permission#CHANGE_LOWPAN_STATE}</li>
- <li>TBD</li>
-</ul>
-
-<p class="note"><strong>Note:</strong> Not all Android-powered devices provide LoWPAN functionality.
-If your application uses these APIs, declare so with a <a
