Get value from RemoteMessage from FCM onMessageReceived method

Question

I have migrate gcm to fcm for push notification message. but how I Get bundle data from RemoteMessage received onMesssageReceived method.

Old GCM give bundle data onMessageReceiced method but in FCM there is RemoteMessage data.

So please tell me how I parse remotemessage for get all value of notification.

MY PAYROL

{
"collapse_key":"score_update",
"priority":"high",
"content_available":true,
"time_to_live":108,
"delay_while_idle":true,
"data": 
{ 
    "message": "Message for new task",
    "time": "6/27/2016 5:24:28 PM"
},
"notification": {
    "sound": "simpleSound.wav",
    "badge": "6",
    "title": "Test app",
    "icon": "myicon",
    "body": "hello 6 app",
    "notification_id" : "1140",
    "notification_type" : 1,
    "notification_message" : "TEST MESSAGE",
    "notification_title" : "APP"
  },
"registration_ids": ["cRz9SJ-gGuo:APA91bFJPX7_d07AR7zY6m9khQro81GmSX-7iXPUaHqqcOT0xNTVsOZ4M1aPtoVloLNq71-aWrMCpIDmX4NhMeDIc08txi6Vc1mht56MItuVDdA4VWrnN2iDwCE8k69-V8eUVeK5ISer"
]
}

Solution 1

In FCM you received RemoteMessage instead of Bundle.

Below is the way I used in my application where data is my RemoteMessage

Map<String, String> data = remoteMessage.getData()
int questionId = Integer.parseInt(data.get("questionId").toString());
String questionTitle = data.get("questionTitle").toString();
String userDisplayName = data.get("userDisplayName").toString();
String commentText = data.get("latestComment").toString();

Below is my notification data which I am sending it from server

{
  "registration_ids": "",
  "data": {
    "questionId": 1,
    "userDisplayName": "Test",
    "questionTitle": "Test",
    "latestComment": "Test"
  }
}

So you have to parse each and every field as per your response. As I have debugged the code you will receive map in your RemoteMessage and cast those fields in appropriate data types as all those data comes as string.

Solution 2

Here is the code snippet which is pretty much self Explanatory.

You get the data in the form of the Map

public void onMessageReceived(RemoteMessage remoteMessage)
        {
            Log.e("dataChat",remoteMessage.getData().toString());
            try
            {
                Map<String, String> params = remoteMessage.getData();
                JSONObject object = new JSONObject(params);
                Log.e("JSON_OBJECT", object.toString());
          }
       }

Make Sure from server you are sending data in correct format i.e. in the "data" key

here is the demo Json file

{
  "to": "registration_ids",
  "data": {
    "key": "value",
    "key": "value",
    "key": "value",
    "key": "value"
  }
}

Solution 3

For your data that looks like:

"data":{ 
    "message": "Message for new task",
    "time": "6/27/2016 5:24:28 PM"
}

you should get them through

Log.d(TAG, "Key Data : " +  remoteMessage.getData().get("message").toString());
Log.d(TAG, "Key Data : " +  remoteMessage.getData().get("time").toString());

Wrap them in try catch to be sure

Solution 4

The type of fun getData() is Map<String, String>. So you can fetch data object values like we usually fetch with Map<String, String>.

"data": {
    "key1": "value1",
    "key2": "value2",
    "key3": "value3",
    "key4": "value4"
  }

then you have to fetch like this in kotlin

val data = remoteMessage.data
val key1 = data[key1]
val key2  = data[key2]// you can fetch like this

For getNotification() type is Notification object

val notification: Notification =  remoteMessage.notification
val message = notification.body
val title = notification.title // you can fetch by accessing Notification class member

Here are the details about the Notification object
