<p>Provides classes to manage Wi-Fi functionality on the device.</p>
|
|
<p>The Wi-Fi APIs provide a means by which applications can communicate
|
|
with the lower-level wireless stack that provides Wi-Fi network access. Almost all
|
|
information from the device supplicant is available, including the connected network's
|
|
link speed, IP address, negotiation state, and more, plus information about other
|
|
networks that are available. Some other API features include the ability to
|
|
scan, add, save, terminate and initiate Wi-Fi connections.</p>
|
|
|
|
<p>Some APIs may require the following user permissions:</p>
|
|
<ul>
|
|
<li>{@link android.Manifest.permission#ACCESS_WIFI_STATE}</li>
|
|
<li>{@link android.Manifest.permission#CHANGE_WIFI_STATE}</li>
|
|
<li>{@link android.Manifest.permission#CHANGE_WIFI_MULTICAST_STATE}</li>
|
|
</ul>
|
|
|
|
<p class="note"><strong>Note:</strong> Not all Android-powered devices provide Wi-Fi functionality.
|
|
If your application uses Wi-Fi, declare so with a <a
|
|
href="{@docRoot}guide/topics/manifest/uses-feature-element.html">{@code <uses-feature>}</a>
|
|
element in the manifest file:</p>
|
|
<pre>
|

<manifest ...>
|
|
<uses-feature android:name="android.hardware.wifi" />
