   <intent-filter android:priority="100">

   </intent-filter>
</receiver>

BroadcastReceiver class

public class WifiReceiver extends BroadcastReceiver {

   @Override
   public void onReceive(Context context, Intent intent) {

      NetworkInfo info = intent.getParcelableExtra(WifiManager.EXTRA_NETWORK_INFO);
      if(info != null && info.isConnected()) {
        // Do your work. 

        // e.g. To check the Network Name or other info:
        WifiManager wifiManager = (WifiManager)context.getSystemService(Context.WIFI_SERVICE);
        WifiInfo wifiInfo = wifiManager.getConnectionInfo();
        String ssid = wifiInfo.getSSID();
      }
   }
}
