I tried to send request to FCM/firease Cloud Messaging for push notification to android device but every time in get ("MissingRegistration"). I can't the correct format of json to push notification. This is the json format how I Sent
{ "registration_ids": [ "/*FirebaseInstanceId.getInstance().getToken()*/" ] , "notification" : { "title": "Portugal vs. Denmark" , "text": "5 to 1" } }
I need for all any a idea.
