If my React Native app fails to connect to its backend, I show an Alert with an OK button. If this happens, there's no point in the app continuing to run, so I'd like to shut it down when the button is clicked. How do I do this?

I suspect the key is in AppRegistry but the docs are a bit scant.

For Android, Use BackHandler to exit the App:

import React, { BackHandler } from 'react-native';

BackHandler.exitApp();
