Below I have shared my code. can anyone please help me? Thanks in advance.

  async checkPermission() {
    const enabled = await firebase.messaging().hasPermission();
    if (enabled) {
        this.getToken();
      } else {
        this.requestPermission();
     }
    let channel = new firebase.notifications.Android.Channel(
      "channelId",
      "Channel Name",
      firebase.notifications.Android.Importance.Max
    ).setDescription("A natural description of the channel");
    firebase.notifications().android.createChannel(channel);


    firebase
      .notifications()
      .getInitialNotification()
      .then(notificationOpen => {
        if (notificationOpen) {
          const action = notificationOpen.action;
          const notification = notificationOpen.notification;
        }
      });

    // the listener returns a function you can use to unsubscribe
    this.unsubscribeFromNotificationListener = firebase
      .notifications()
      .onNotification(notification => {

        if (Platform.OS === "android") {
          const channel = new firebase.notifications.Android.Channel(

Answer 1

Give this a try.

First of all place your sound file in res/raw folder and also include setSound() in the notification channel ,

Second point, thanks to @PatelDhara also make sure to remove your app from your device, so that new channel configuration will work properly.

Then put below line of code, it is working fine for me.

First create the channel.

const channel = new firebase.notifications.Android.Channel(name, Description, firebase.notifications.Android.Importance.High)
.setDescription(ChannelName)
.setSound(default.mp3) //Set audio here
...
firebase.notifications().android.createChannel(channel);

Then:

const notification = new firebase.notifications.Notification()
.setNotificationId(id)
.setTitle(title)
.setSound(channel.sound); //Get sound from channel and set in notification builder

notification
.android.setChannelId(channel.channelId)
firebase.notifications().displayNotification(notification);

Also make sure that whenever you get payload, your audio file name located in your res/raw folder and sound value you are getting in payload should be same.

Like this:

{
    "to" : "DEVICE-TOKEN",

    "notification" : {
      "body"  : "NOTIFICATION BODY",
      "title" : "NOTIFICATION TITILE",
      "sound" : "default"
    }
  }

Note : In react native there was problems with Android O in versions before 0.56.0(react native version), So try to upgrade your version.

Answer 2

After spending the whole day, I have found the solution. I have just cleared app data and restart my phone and it's working fine.

There is an issue because I have used custom sound on a particular type of notification.

I have also passed channel Id in the payload, to get a different sound based on the type of notification when the app is a background and kill mode.

{
    "to" : "DEVICE_TOKEN",

    "notification" : {
      "body"  : "NOTIFICATION BODY",
      "title" : "NOTIFICATION TITILE",
      "sound" : "default", //change your sound based on your requirement
      "android_channel_id":"CHANEEL_NAME", 
    }
  }
