To initiate a Wi-Fi scan, declare the android.Manifest.permission#CHANGE_WIFI_STATE permission in the manifest, and perform these steps:
<ol style="1"> <li>Invoke the following method: ((WifiManager) getSystemService(WIFI_SERVICE)).startScan()</li> <li> Register a BroadcastReceiver to listen to SCAN_RESULTS_AVAILABLE_ACTION.</li> <li>When a broadcast is received, call: ((WifiManager) getSystemService(WIFI_SERVICE)).getScanResults()</li> </ol>
This member is deprecated. The ability for apps to trigger scan requests will be removed in a future release.
