React-Native: Go back on android hardware back button pressed

Question

I am trying to add going back on webview when the android backbutton was pressed and I still couldn\'t manage to make it work.

This is my code:

Answer 1

class MyComponent extends Component {
    state = {};
    componentDidMount(){
         BackHandler.addEventListener('hardwareBackPress', this.backHandler);
    }
    componentWillUnmount(){
         BackHandler.removeEventListener('hardwareBackPress', this.backHandler);
    }
    backHandler = () => {
        if(this.state.backButtonEnabled) {
            this.refs[WEBVIEW_REF].goBack();
            return true;
        }
    }
}

1) Bind your handler 2) Do not forget to removeListener on unmount.
