may be this should be problem and also try removing '.mp3' in sound element and make it like

Answer 2

Maybe this helps : In my case i tried with the above approach and it did not worked, whenever i was checking in the onMessageReceived (for debug purpose) the channel id

Log.e(TAG, "Message Notification channel id: " + remoteMessage.getNotification().getChannelId()); 

i always got 'null'.

So reading the documentation from here https://firebase.google.com/docs/cloud-messaging/http-server-ref#notification-payload-support

I found out that i was using the wrong key for the channel id in the json.

Instead of 'channel_id' key try to use 'android_channel_id' key like this

"notification": {
        "body": "Body of Your Notification",
        "title": "Title of Your Notification",
        "android_channel_id": "channelId",
        "icon": "myIcon"
    }

If i use it like that it works as expected, custom sound (from res/raw) is played

PS: in my case i set my sound on the channelId when i created it

Good luck !

Finally I found the solution. For Android 8.0 and higher it's necessary to create a notification channel in your App:

NotificationChannel channel = new NotificationChannel('my_id', name, importance);

(more info: https://developer.android.com/training/notify-user/channels#java)

Then when you send the notification:

var registrationToken = 'xxxxxx';

var message = {

    notification: {
      title: 'my title',
      body: 'my body',
    },
    android: {
      ttl: 3600 * 1000,
      notification: {
        color: '#ff0000',
        sound: 'mysound.mp3',
        channel_id: 'my_id' // important to get custom sound
      }
    }, 
    token: registrationToken

};

I was also looking for the solution to custom sound for firebase notification in the android, And I have solved this problem through Notification Channel.

I have created one notification channel with custom sound, that sound plays after receiving notification in the application background state.

You can refer following links of the notification channel.

https://medium.com/exploring-android/exploring-android-o-notification-channels-94cd274f604c

https://developer.android.com/training/notify-user/channels

You need to put your mp3 file at /res/raw/ path.

Please find the code.

NotificationManager notificationManager = (NotificationManager) getActivity().getSystemService(NotificationManager.class); // If you are writting code in fragment

OR

NotificationManager notificationManager = (NotificationManager) getSystemService(NotificationManager.class); // If you are writting code in Activity

createNotificationChannel function

private void createNotificationChannel() { 
 Uri sound = Uri.parse(ContentResolver.SCHEME_ANDROID_RESOURCE + "://" + context.getPackageName() + "/" + R.raw.sample); //Here is FILE_NAME is the name of file that you want to play 
// Create the NotificationChannel, but only on API 26+ because 
// the NotificationChannel class is new and not in the support library if 
(Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) 
 { 
    CharSequence name = "mychannel"; 
    String description = "testing"; 
    int importance = NotificationManager.IMPORTANCE_DEFAULT; 
    AudioAttributes audioAttributes = new AudioAttributes.Builder() 
     .setContentType(AudioAttributes.CONTENT_TYPE_SONIFICATION) 
     .setUsage(AudioAttributes.USAGE_ALARM) 
     .build(); 
   NotificationChannel channel = new NotificationChannel("cnid", name, importance); 
   channel.setDescription(description); 
   channel.enableLights(true); channel.enableVibration(true); 
   channel.setSound(sound, audioAttributes); 
   notificationManager.createNotificationChannel(channel); 
  } 
};

createNotificationChannel(); 

To achieve this you need to pass android_channel_id property in the firebase notification request object.

{
 "notification": {
 "body": "this is testing notification",
 "title": "My App",
 "android_channel_id": "cnid"
 },
 "to": "token"
}

Note - If you create a notification channel once then you can't change the sound. You have to create a new notification channel with the new name with your desired sound.

Answer 5

From the documentation, include the sound in notification object under android object. Give name of the sound file in sound value. The sound files must reside in /res/raw/ . Below is a Node.js example:-

  var message = {
  notification: {
    title: 'sample title',
    body: 'Hello, its Tuesday.',
  },
  android: {
    ttl: 3600 * 1000,
    notification: {
      icon: 'my_icon',
      color: '#f45342',
      sound: 'filename.mp3',
    },
  },
  apns: {
    payload: {
      aps: {
        badge: 42,
      },
    },
  },

i was also facing the same issue. I always got the default sound but i fixed it as follows . I am using FCM-push (node module) https://www.npmjs.com/package/fcm-push

var message = {  
to : device_token,
collapse_key : '<insert-collapse-key>',
// data : {
//     '<random-data-key1>' : '<random-data-value1>',
//     '<random-data-key2>' : '<random-data-value2>'
// },
notification : {
    title : 'Title ',
    body : 'some Body',
    sound : 'notification' // my .ogg file in /res/raw
},
android: {
sound: 'notification' // my .ogg file name in /res/raw
}
};

I have not tried it with mp3 or wav and in your question it seems you have not tried with .ogg file ( though i doubt if it has anything to do with audio format but you can try)
