I was also having a problem with notifications that had to emit sound, when the app was in foreground everything worked correctly, however when the app was in the background the sound just didn't come out.

The notification was sent by the server through FCM, that is, the server mounted the JSON of the notification and sent it to FCM, which then sends the notification to the apps. Even if I put the sound tag, the sound does not come out in the backgound.

Even putting the sound tag it didn't work.

After so much searching I found the solution on a github forum. I then noticed that there were two problems in my case:

1 - It was missing to send the channel_id tag, important to work in API level 26+

2 - In the Android application, for this specific case where notifications were being sent directly from the server, I had to configure the channel id in advance, so in my main Activity I had to configure the channel so that Android knew what to do when notification arrived.

In JSON sent by the server:

   {
  "title": string,
  "body": string,
  "icon": string,
  "color": string,
  "sound": mysound,

  "channel_id": videocall,
  //More stuff here ...
 }

In your main Activity:

 @Background
    void createChannel(){
            Uri sound = Uri.parse("android.resource://" + getApplicationContext().getPackageName() + "/" + R.raw.app_note_call);
            NotificationChannel mChannel;
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
                mChannel = new NotificationChannel("videocall", "VIDEO CALL", NotificationManager.IMPORTANCE_HIGH);
                mChannel.setLightColor(Color.GRAY);
                mChannel.enableLights(true);
                mChannel.setDescription("VIDEO CALL");
                AudioAttributes audioAttributes = new AudioAttributes.Builder()
                        .setContentType(AudioAttributes.CONTENT_TYPE_SONIFICATION)
                        .setUsage(AudioAttributes.USAGE_ALARM)
                        .build();
                mChannel.setSound(sound, audioAttributes);

                NotificationManager notificationManager =
                        (NotificationManager) getApplicationContext().getSystemService(Context.NOTIFICATION_SERVICE);
                notificationManager.createNotificationChannel(mChannel);
            }
    }

This finally solved my problem, I hope it helps someone not to waste 2 days like I did. I don't know if it is necessary for everything I put in the code, but this is the way. I also didn't find the github forum link to credit the answer anymore, because what I did was the same one that was posted there.

try this        public  void buildPushNotification Context ctx  String content  int icon  CharSequence text  boolean silent        Intent intent   new Intent ctx  Activity class       intent addFlags Intent FLAG ACTIVITY CLEAR TOP       PendingIntent pendingIntent   PendingIntent getActivity ctx  1410  intent  PendingIntent FLAG ONE SHOT        Bitmap bm   BitmapFactory decodeResource ctx getResources      large drawable        NotificationCompat Builder notificationBuilder   new NotificationCompat Builder ctx               setSmallIcon icon               setLargeIcon bm               setContentTitle content               setContentText text               setAutoCancel true               setContentIntent pendingIntent        if  silent         notificationBuilder setSound RingtoneManager getDefaultUri RingtoneManager TYPE NOTIFICATION      NotificationManager notificationManager    NotificationManager  ctx getSystemService Context NOTIFICATION SERVICE            notificationManager notify 1410  notificationBuilder build                and in onMessageReceived  call it     Override public void onMessageReceived RemoteMessage remoteMessage          Log d  Msg    Message received      remoteMessage getNotification   getBody                buildPushNotification   your param         or follow KongJing  Is also correct as he says  but you can use a Firebase Console

The onMessageReceived method is fired only when app is in foreground or the notification payload only contains the data type    From the Firebase docs     For downstream messaging  FCM provides two types of payload    notification and data        For notification type  FCM automatically displays the message to   end-user devices on behalf of the client app  Notifications have a   predefined set of user-visible keys    For data type  client app is responsible for processing data messages  Data messages have only custom key-value pairs         Use notifications when you want FCM to handle displaying a   notification on your client app s behalf  Use data messages when you   want your app to handle the display or process the messages on your   Android client app  or if you want to send messages to iOS devices   when there is a direct FCM connection    Further down the docs     App behaviour when receiving messages that include both notification   and data payloads depends on whether the app is in the background or   the foreground   essentially  whether or not it is active at the time of   receipt    When in the background  apps receive the notification payload   in the notification tray  and only handle the data payload when the   user taps on the notification    When in the foreground  your app receives a message object with both payloads available    If you are using the firebase console to send notifications  the payload will always contain the notification type  You have to use the Firebase API to send the notification with only the data type in the notification payload  That way your app is always notified when a new notification is received and the app can handle the notification payload   If you want to play notification sound when app is in background using the conventional method  you need to add the sound parameter to the notification payload

In the notification payload of the notification there is a sound key   From the official documentation its use is      Indicates a sound to play when the device receives a notification    Supports default or the filename of a sound resource bundled in the   app  Sound files must reside in  res raw     Eg           to     bk3RNwTe3H0 CI2k HHwgIpoDKCIZvvDMExUdFQ3P1            notification             body     great match           title     Portugal vs  Denmark          icon     myicon          sound     mySound              If you want to use default sound of the device  you should use   sound    default    See this link for all possible keys in the payloads  https   firebase google com docs cloud-messaging http-server-ref notification-payload-support  For those who don t know firebase handles notifications differently when the app is in background  In this case the onMessageReceived function is not called      When your app is in the background  Android directs notification   messages to the system tray  A user tap on the notification opens the   app launcher by default  This includes messages that contain both   notification and data payload  In these cases  the notification is   delivered to the device s system tray  and the data payload is   delivered in the extras of the intent of your launcher Activity
