title: how to get current wifi connection info in android
body: <p>I'm trying to find if <code>scanResult</code> is the current connected wifi network.</p>
  
  <p>here is my code</p>
  
  <pre><code>public boolean IsCurrentConnectedWifi(ScanResult scanResult) 
  {
      WifiManager mainWifi = (WifiManager) getSystemService(Context.WIFI_SERVICE);
      WifiInfo currentWifi = mainWifi.getConnectionInfo();
      if(currentWifi != null)
      {
          if(currentWifi.getSSID() != null) 
          {
              if(currentWifi.getSSID() == scanResult.SSID)
              return true;
          }
      }  
      return false;
  }
  </code></pre>
  
  <p>I have no problem on getting scanresult.</p>
  
  <p>Always I'm getting currentWifi is null.</p>
  
  <p>Where am I wrong or Is there any alternative method to do this?</p>
