title: Netinfo.isConnected always returns true in Android
body: <p>i am using <a href="https://github.com/react-native-community/react-native-netinfo" rel="nofollow noreferrer">react-native-netinfo</a> in my app. In iOS it's working fine. But in android always returns true. It doesn't have internet connection (WiFi or Mobile data). It still returns true. Please give me any suggestions.</p>
  
  <p><strong>Versions:-</strong></p>
  
  <pre><code>react-native:- 0.61.4,
  @react-native-community/netinfo:- 4.6.1
  </code></pre>
  
  <p>Here is my code:-</p>
  
  <pre><code>  componentDidMount() {
      NetInfo.isConnected.addEventListener(
        'connectionChange',
        this.handleConnectivityChange,
      );
    }
    handleConnectivityChange = isConnected =&gt; {
      console.log('uyeuiyiuyiu', isConnected);
      this.setState({
        connectionStatus: isConnected,
      });
    };
    componentWillUnmount() {
      NetInfo.isConnected.removeEventListener(
        'connectionChange',
        this.handleConnectivityChange,
      );
    }
  </code></pre>
