Firebase Cloud Messaging（FCM）无法获取数据

Question

I'm sending push notification using FCM to Android device.

I'm using java based google API client for sending messages.

FCM request body for message using common notification object:

{
 "message": {
"notification": {
  "title": "FCM Notification",
  "body": "Notification from FCM"
},
"data": {
  "k1": "v1",
  "k2": "v2"
},
"token": "eeNFUXuDQ:APA91bGaLh5UeJcyJctFWlvC32ezPk7ZWp-D05ImpPWbSv_yc49igOioyBOMZg3bxl8L8fvNWTQW6LcptwZoiOwHtIN24uNHox1s2ql1Ir5Rm9Jk1DXPAPe79o20GXHZhY04-TRzpaXe"
}
}

Message sent to Firebase for delivery, response:

{  
"name": "projects/lacoya-1540956670279/messages/0:1544690320409950%b4fb2744b4fb2744"
}

But, in my android device, I'm getting only title value "FCM Notification" as a notification but I want to see some data as well like some custom JSON.

Please through some light if you face this earlier.

Regards,

There was some some problem with android code. After using correct callback method, we are getting data. Below is the useful link.
