How to retrieve notification message intent.getExtras() when app is background FCM

Question

I am using FCM for Simple notification

When the app is in foreground, everything working properly. I am getting a notification plus the data message inside the onMessageReceived method.

But when app is in background, I am getting notification in system tray. And when I click on the control, it goes to the main activity. And When I parse intent.getExtras();, I am getting only this key data - google.sent_time, from, google.message_id, collapse_key.

How to get the notification message title and Message which is visible in system tray from intent.getExtras()?

I am using FCM console for sending notification I don't have my dedicated server to do this.

Code for receiving the message:

final Bundle extras = intent.getExtras(); 
final Set<String> keySet = extras.keySet(); 
final Iterator<String> iterator = keySet.iterator(); 
while (iterator.hasNext()) {     
    final String key = iterator.next(); 
    final Object o = extras.get(key); 
    System.out.println(key + ":" + o); 
}

As seen in the Handling Messages for Android FCM docs, if the payload you sent has both notification and data, it will be handled separately. The notification part will be handled by the Notification Tray, while the data part will be in the extras of the intent.

AFAIK, there is no way to get the notification payload when the app is in background (always handled by the Notification Tray). However, what you could do is add custom key-value pairs to your data payload instead, like so:

{
"data": {
      "notification_title": "title here",
      "notification_message": "message here"
     }
}

Of course you'll have to make sure that the data value for notification_title and notification_message is the same as to what you set it in the notification payload. Then just retrieve it from the Intent extras like usual.
