Question

I need to detect when I have network connectivity to a SPECIFIC WIFI network.

For example: As soon as you walk into your house, and your phone picks up your home Wi

Use the standard code to list all available networks:

• start the scan

  String connectivity_context = Context.WIFI_SERVICE;
              final WifiManager wifi = (WifiManager) getSystemService(connectivity_context);  
  if (wifi.isWifiEnabled()) {
                          wifi.startScan();
                      }
  

• register a receiver for the data

  IntentFilter i = new IntentFilter();
  i.addAction(WifiManager.SCAN_RESULTS_AVAILABLE_ACTION);
  
  BroadcastReceiver receiver = new BroadcastReceiver() {
      @Override
      public void onReceive(Context context, Intent i) {
          // TODO Auto-generated method stub
          ScanWiFiActivity a = ScanWiFiActivity.instance();
          WifiManager w = (WifiManager) context
                  .getSystemService(Context.WIFI_SERVICE);
          List l = w.getScanResults();
          a.Clear();
          for (ScanResult r : l) {
                                //use r.SSID or r.BSSID to identify your home network and take action
              a.setText(r.SSID + "" + r.level + "\r\n");
          }
      }
  };
  registerReceiver(receiver, i);
  

In the FOR block work your magic and take action when you identify your network by SSID or BSSID
