Sendbird push notification when app is in background

Question

Here is my query. I have implemented sendbird sdk in one of my react-native app for chat implementation. I am trying to implement push notifications. I have used react-native-firebase for firebase push notifications as described in sendbird's documentation. Now the issue is my android app is getting push notification when the app is in foreground. OnMessageReceived() listener is triggered for this. But when my app is in background I am not receiving any push notification from sendbird.. None of the firebase notification listeners are triggered.

Also, when I am trying to send notification from firebase console I am receiving foreground as well as background notification.

Hoping for a response from you guys, as this can help me implement this feature successfully.

My notification listener code is similar to this. But, here haven't added display notification code though.

async componentDidMount() {
  this.checkPermission();
  this.createNotificationListeners(); //Notification listener 
}

 async createNotificationListeners() {
  /*
  * Triggered when a particular notification has been received in foreground
  * */
  this.notificationListener = firebase.notifications().onNotification((notification) => {
      const { title, body } = notification;
      this.showAlert(title, body);
  });

  /*
  * If your app is in background, you can listen for when a notification is clicked / tapped / opened as follows:
  * */
  this.notificationOpenedListener = firebase.notifications().onNotificationOpened((notificationOpen) => {
      const { title, body } = notificationOpen.notification;
      this.showAlert(title, body);
  });

  /*
  * If your app is closed, you can check if it was opened by a notification being clicked / tapped / opened as follows:
  * */
  const notificationOpen = await firebase.notifications().getInitialNotification();
  if (notificationOpen) {
      const { title, body } = notificationOpen.notification;
      this.showAlert(title, body);
  }
  /*
  * Triggered for data only payload in foreground
  * */
  this.messageListener = firebase.messaging().onMessage((message) => {
    //process data message
    console.log(JSON.stringify(message));
  });
}

showAlert(title, body) {
  Alert.alert(
    title, body,
    [
        { text: 'OK', onPress: () => console.log('OK Pressed') },
    ],
    { cancelable: false },
  );
}
}

My AndroidManifest.xml code is as below:-

So finally after lot of research, I successfully got the solution by refering to the Sendbird's sample App, pasting link below.

https://github.com/sendbird/SendBird-JavaScript/tree/master/react-native-redux-sample

Solution:-

You need to register channel in App. Js componentDidMount().

//code for app js

componentDidMount(){
const channel = new firebase.notification.Android.Channel(
"YOUR-CHANNEL-ID",
"CHANNEL NAME",
firebase.notification.Android.Importance.Max).setDescription("description);
firebase.notifications().android.createChannel(chanel);


//don't forget to add handler for app state change
Appstate.addEventListener('change',this._handleAppStateChange);

)
}

_handleAppStateChange = currentAppState =>{
  const sb = SendBird.getInstance();
if(sb)
{
   if(currentAppState == "active")
  {
     sb.setForegroundState();
  }
else if(currentAppState == "background")
{
   sb.setBackgroundState();
}
}

//NOW in main index.js add below lines

import backgroundPush from './Services/push';

AppRegistry.registerHeadlessTask('RNFirebaseBackgroundMessage',()=>backgroundPush) //add this line after appRegistry Component and this is a key to be added to get notitification in background when using sendbird, whicch is nowhere mentioned in its official doc. It is in the sample App I have also added link to it.

And the push/backgroundPush that imported is a file containing below source:-

push.js //this file is in sample app though

import firebase from 'react-native-firebase'

export default async message => {
  try {
    const text = message.data.message;
    const payload = JSON.parse(message.data.sendbird);
    const localNotification = new firebase.notifications.Notification({
      show_in_foreground: true
    }).android
      .setChannelId('channel_id')
      .android.setSmallIcon('sendbird_ic_notification')
      .android.setPriority(firebase.notifications.Android.Priority.High)
      .setNotificationId(message.messageId)
      .setTitle('New message')
      .setSubtitle(`Unread message: ${payload.unread_message_count}`)
      .setBody(text)
      .setData(payload);
    return firebase.notifications().displayNotification(localNotification);
  } catch (e) {
    return Promise.resolve();
  }
};

This is the solution worked for me for my query Android background push notification now received. Although, still struggling with receiving push notificaiton iOS side.

Thanks.
