How to handle Android FCM Messages when application is in Background with data payload? [duplicate]

Question

Android push notification using FCM is unable to handle when application in background. Default message is displayed in notification tray.

Can Anyone help me how to handle the messages when application in background.

@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
    super.onMessageReceived(remoteMessage);

}

This method is not called when application is in background. Any help will be great help for me.

Answer 1

The onMessageReceived() will be always called if you receive the payload as "data" always from server.

Example : Payload from server should be like following :

{
 "data":{
 "id": 1,
 "missedRequests": 5
 "addAnyDataHere": 123
 },
 "to":"fhiT7evmZk8:APA91bFJq7Tkly4BtLRXdYvqHno2vHCRkzpJT8QZy0TlIGs......"
}
