+<a name="androidWifiIntroduction"></a><h2>Introduction</h2>
+
+<p>Android uses wpa_supplicant as the platform interface to the Wi-Fi device. Your Wi-Fi driver must be compatible with the standard wpa_supplicant in addition to extensions added to the supplicant (specifically, the "DRIVER" commands described in <code>wifi.h/wifi_command()</code>).</p>
+
+
+<a name="androidWifiBuildingDriver"></a><h2>Building a Wi-Fi Library</h2>
+
+<p>To create a Wi-Fi driver for Android:</p>
+<p><ul>
+<li>create a shared library that implements the interface defined in <code>include/hardware/wifi.h</code>, which also defines the Wi-Fi supplicant.</li>
+<li>Follow the instructions posted at <a href="http://hostap.epitest.fi/wpa_supplicant/">http://hostap.epitest.fi/wpa_supplicant/</a>.</li>
+<li>Place your driver in <code>libs/hardware/wifi/</code></li>
+<li>Test your driver using the command line <code>wpa_cli</code> utilities.</li>
+</ul>
+
+<p>You can find the default implementation in <code>libs/hardware/wifi/wifi.c</code>. If you need to make changes, create a new source file similar to <code>wifi.c</code>, for example, <code>wifi_mywifi.c</code>. </p>
+
+<p>Update the default <code>Android.mk</code> file (<code>libs/hardware/wifi/Android.mk</code>) as shown below.</p>
