const AndroidBackButton = (WrappedComponent) => {

  return class extends Component {

      super(props)
    }

    componentDidMount() {
      this.backHandler = BackHandler.addEventListener('hardwareBackPress', () => {
        this.props.history.goBack() // for react-router-dom -> https://github.com/ReactTraining/react-router
        return true;
      });
