Send FCM messages from server side to android device

Question

With the new update, FCM is now going to be used.

I tried the sample app from git and it\'s working all fine. I can send notifications from the console.

But

Answer 1

In order to receive the notification using remoteMessage.getNotification().getBody(), you have to use the predefined set of key option for notification.

In this case, "notification" is the key word.

The JSON response has to be formatted like this.

   {
      "to" : "bk3RNwTe3H0:CI2k_HHwgIpoDKCIZvvDMExUdFQ3P1...",
      "notification" : {
          "body" : "great match!",
          "title" : "Portugal vs. Denmark",
          "icon" : "myicon"
      }
   }

You can also send notification and data payload in the same JSON response

 {
    "to" : "APA91bHun4MxP5egoKMwt2KZFBaFUH-1RYqx...",
    "notification" : {
        "body" : "great match!",
        "title" : "Portugal vs. Denmark",
        "icon" : "myicon"
    },
    "data" : {
        "Nick" : "Mario",
        "Room" : "PortugalVSDenmark"
    }
 }
