Android PUSH: GCM error: Missing registration_ids field

Hello,                                                                        

When trying to send the registration_id in the format requested in the site I got the error: 'Missing registration_ids field'. Sending it as an array worked as shown below.

Initial: 

Content-Type:application/json

Authorization:key=AIzaSyB-1uEai2WiUapxCs2...

{

  "registration_id" : "APA91bHun4MxP5egoKMwt2KZF....",

  "data" : {

    "Team" : "Portugal",

    "Score" : "3",

    "Player" : "Varela",

  },

}

Gives the following error: Missing "registration_ids" field

Use:                                                                            {

  "registration_ids" : ["APA91bGSnrAvxspEngNfGqd4JDsl00..."],

  "data" : {

    "Team" : "Portugal",

    "Score" : "3",

    "Player" : "Varela",

  },

}

Hope this helps !
