React Native Push Notification onNotification callback is inconsistent

问题

I've been using react-native-push-notification library for quite some time for local notifications. Now I need remote silent notifications. Basically I send a notification that gets delivered to onNotification callback and I send local notification to the notification center.

I expect onNotification callback to trigger every time I receive notification and I open an app by clicking on notification. The problem is, depending on where I call PushNotification.configure({...}), on Android it triggers onNotification when notification gets delivered OR when I click on it, but never both! My code:

// if here: calls onNotification when it's received
PushNotifications.configureNotifications();

export default class App extends React.Component {
    constructor(props) {
        // if here: calls onNotification when I click on it to open an app
        PushNotifications.configureNotifications();
        super(props);
    }

    render() { ... }
}

PushNotifications.configureNotifications() - it's just a simple wrapper over the library configure call. Yes, tried to keep it in both places - doesn't work. What am I doing wrong?

I always send data payload in push notification.

Documentation says to not put the configuration in the React life-cycle. Otherwise Android won't have the right behavior (I had so mush pain with this point !). Here you have a nice tutorial: https://product.farewell.io/visible-react-native-push-notifications-that-work-on-both-ios-and-android-5e90badb4a0f It's bad explained, but the approach is perfect. Use a class to initialize and call the methods. Initialize the class in the top component as he suggests. It works good.
