Answer 1

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

Answer 2

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.

Answer 3

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"
  }
}
