No custom sound with Android Firebase Notification

问题

I am using Firebase push notifications in my Android App. I can send correctly notification with custom icon, but I have not managed to play my custom sound. I always get the default sound of my device.

{
    "registration_ids": "myToken",
    "notification": {
        "body": "my body",
        "title": "my title",
        "icon": "ic_notification",
        "sound": "mysound.mp3" // I tried "mysound", "mysound.wav"...

    },
    "priority": "high"

}

The custom sound is located in /res/raw

I have been able to play my custom sound with onMessageReceived and Firebase data message but not with Firebase notification message.

My android device is Xiaomi Mi A1 and Oreo 8.1., also tried with Xiaomi Mi A2 with same result.

I tried with php and curl, with node.js... always same problem, I get my default sound.

UPDATE

With this code for node.js does not work either:

var registrationToken = 'xxxxxx';

var message = {

    notification: {
      title: 'my title',
      body: 'my body',
    },
    android: {
      ttl: 3600 * 1000,
      notification: {
        color: '#ff0000',
        sound: 'mysound.mp3'
      }
    }, 
    token: registrationToken

};

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

};

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,
      },
    },
  },

};

Try Enabling Sound From Firebase Console

For More Info Just Look at this answer

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

"sound":"mySound"

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)

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 !
