How to get subtitle from firebase push notification

Question

I am getting push notification in this format from server.

{
                title: messageTitle,
                body: messageBody,
               subtitle: messageSubtitle
}

In my android project i read notification by using following code.

remoteMessage.getNotification().getTitle();
remoteMessage.getNotification().getBody();

The above 2 lines gives me Title and Body, but i am unable to understand how to read subtitle property.

//remoteMessage is reference of RemoteMessage

 `val data = remoteMessage.data

    if(data.isNotEmpty())
    {

        if (data.containsKey("title"))
            title = data["title"].toString()

        if (data.containsKey("body"))
            body = data["path"].toString()

        if(data.containsKey("subtitle"))
            subtitle = data["subtitle"].toString()

        if(data.containsKey("notifyId"))
            notifyId = data["notifyId"]?.toInt()

        }`

Standard notification format does not include subtitle hence there is no method to fetch it, to get a subtitle message please use data key.

Standard Notification format

{
  "message":{
    "token":"bk3RNwTe3H0:CI2k_HHwgIpoDKCIZvvDMExUdFQ3P1...",
    "notification":{
      "title":"Portugal vs. Denmark",
      "body":"great match!"
    }
  }
}

if you want a subtitle please add subtitle to data field and then then fetch using getData() method

Customized Notification for subtitle

{
  "message":{
    "token":"bk3RNwTe3H0:CI2k_HHwgIpoDKCIZvvDMExUdFQ3P1...",
    "notification":{
      "title":"Portugal vs. Denmark",
      "body":"great match!"
    },
    "data" : {
      "subtitle" : "Mario",
      "subHeading" : "PortugalVSDenmark"
    }
  }
}

To recieve FCM notifications with custom data, we need to check the data payloads as follows:-

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.

In case 2 , you can simply check as below:-

String customData = remoteMessage.getData().get("customData");

And for the first case please refer to the answer;-

handle notification with custom data

Hope this helps.
