BACKGROUND ISSUE: launching app, that is running in background didnt trigger press event listener

[rimzici]

node modules versions: "react": "^15.2.1", "react-native": "^0.31.0", "react-native-system-notification": "^0.2.0", "react-native-fcm": "^1.0.16",

tried with "react-native": "^0.29.0", also. have made all config changes told in react-native-system-notification docs.added android:launchMode="singleTask" in manifest file. and issue of app loading every time , even when launching from background got solved, now it resumes. So after that the event listener is not working. Notification.addListener('press', function(e) { console.log(e); }); the listener works when app is running in the foreground. But in the background app launches on clicking notification but event listener not triggered. Any Suggestions ? Thanks in advance.

Where are you registering your press event listening function?

[rimzici]

In the index page inside componentWillMount() { Notification.addListener('press', function(e) { console.log(e); }); }

alse tried with DeviceEventEmitter none works finally i found what could be causing the issue, Not sure yet. I am using SplashScreen for my android app. Suspecting that SplashScreen Activity, one which takes place before my MainAcivity blocking the data? Thanks @andy9775

[andy9775]

Hmm. Can you try registering in the constructor? I had a similar issue where it wasn't getting called and that solved it for me.

You could also be right about the splash screen activity I haven't experienced this type of scenario so I can't really comment on it though.

[colorhaake]

I have used react-native-gcm-android and react-native-system-notification.

Aftre research, the root cause could be: After react native v0.29, all native modules are migrated from MainActivity to MainApplication. Click notificaiton will send intent that contains notification info to launch App. We need to get this intent in app to get its notification info. But GcmModule is loaded before MainActivity launched because of migration of all native modules. So if we get this intent in MainApplication, that could be nothing. We need to get this intent in MainActivity and figure out way to send it into JavaScript side

If my thought is wrong, please point out.

@rimzici i am using react-native-fcm, react-native-system-notification and need to generate push notification on background and foreground. Problem is i am using RN 0.32 and react-native-fcm that provide local-notification on RN > 0.33 So i tried to generate local notification by react-native-system-notification, now i am able to do that on fcm notification event writing react-native-system-notification oncreate event. componentDidMount() { FCM.on('notification', (notif) => { console.log('notif on foregournd', notif, FCM); Notification.create({ subject: 'Hey', message: 'Yo! Hello world.' }); }); but when click on it, it does not work. I have registered react-native-system-notification in willmount like this. componentWillMount() { this.setState({loadSpinner: true}, () => { // FCM.getFCMToken().then(token => { // this.props.dispatch(postPushNotificationDetails(token, DeviceInfo.getUniqueID())); // }); this.props.dispatch(fetchNewOrders(this.state.currentPage)); }); Notification.addListener('press', function(e) { console.log('Notification.addListener(press)'); }); }

The problem here is the following: The module here has two states only, if in foreground to the user, in which case there is no problem. And if the app is not in foreground (background, dead, service-only), in which the notification works only if the app is dead (completely or service-only). If the app is not foreground (from this module's point of view) then an intent to launch the application is sent along with the notification info. This would work only when the app is dead because of this line of code: https://github.com/neson/react-native-system-notification/blob/master/index.android.js#L67 The initial notification is checked when you add a listener to the press/click event only. Which means if the app is coming from the background, and the listener is already hooked, this piece of code won't run! Im trying to find the best solution for this problem as i write this comment. Will do a pull request once im done. But a viable temporary solution would be the following: listen to AppState changes, remove the listener when going to background and re-add it when you transition back to foreground.

componentDidMount() {
      Notification.addListener('press', this.notificationPress);
      AppState.addEventListener('change', this._handleAppStateChange);
}

 _handleAppStateChange(currentAppState) {
   if (currentAppState === 'background') {
     Notification.removeAllListeners('press');
   } else {
     Notification.addListener('press', this.notificationPress);
   }
 },

[freakinruben]

@Sh3rawi I've tried your solution with RN 0.39 but I still don't get any events when the notification is clicked when the app is in the background

[Sh3rawi]

@freakinruben, that worked for us at that time. Currently though, we do not use this library anymore. We switched to fcm from gcm, and react-native-fcm has built-in support for local notifications that covers our needs.
