AppState change listener don't work when the app starts in react-native@0.59.x but work in react-native@0.56.0 #25204
Description
...
class App extends Component {
...
componentDidMount(){
AppState.addEventListener('change', (nextAppState) => console.log(nextAppState));
}
componentWillUnmount() {
AppState.removeEventListener('change');
}
}
...
In react-native@0.56.0, I got the nextAppState is 'active' when the app starts, but in react-native@0.59.9, I got nothing.
React Native version:
App1 use react-native@0.59.9
