     17 <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>

     21 
     22 <p>To create a Wi-Fi driver for Android:</p>
     23 <p><ul>
     24 <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>
     25 <li>Follow the instructions posted at <a href="http://hostap.epitest.fi/wpa_supplicant/">http://hostap.epitest.fi/wpa_supplicant/</a>.</li>
     26 <li>Place your driver in <code>libs/hardware/wifi/</code></li>
     27 <li>Test your driver using the command line <code>wpa_cli</code> utilities.</li>
     28 </ul>
     29 
     30 <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>
     31 
     32 <p>Update the default <code>Android.mk</code> file (<code>libs/hardware/wifi/Android.mk</code>) as shown below.</p>
     33 <pre class="prettify">
     34 LOCAL_SHARED_LIBRARIES += libnetutils
     35 
     36 ifeq ($(TARGET_PRODUCT),acme)
     37 LOCAL_SRC_FILES += wifi/wifi_mywifi.c
     38 else
     39 LOCAL_SRC_FILES += wifi/wifi.c
     40 endif
