React Navigation + Redux close App on Back Pressed

After converting the app to redux, my react-navigation got some problem. Previously, before integrating with redux, when I press back button (Physical button) react-navigation back to the previous screen. After integrating with redux, the back button will close the app. But, it's still working with goBack() function.

• I'm following the guide: https://reactnavigation.org/docs/guides/redux
• And read some code from here : https://github.com/react-community/react-navigation/tree/master/examples/ReduxExample

And, this is my Navigator configuration

export const AppNavigator = StackNavigator(
    {
        Home: { screen: HomeScreen },
        ChatDetail: { screen: ChatDetail },
        PulsaDetail: { screen: PulsaDetailScreen },
        Pulsa: { screen: Pulsa }
    },
    {
        headerMode: 'none',
    }
)

class AppWithNavigation extends Component {
    render(){
        return(
            <AppNavigator navigation={ addNavigationHelpers({
                dispatch: this.props.dispatch,
                state: this.props.nav,
            })} />
        )
    }
}

const mapStateToProps = (state) => ({
  nav: state.nav
})

export default connect(mapStateToProps)(AppWithNavigation)

EDIT: It's can be done with manual handle & dispatch back action, but it's can't do it automaticlly? just like before using redux?

BackHandler.addEventListener('hardwareBackPress',() => {
    this.props.goBack()
    return true
})
