i'm trying to send a notification to my phone via my .php page... everything is set up correctly, but i get the error:
{"multicast_id":7751536172966571167,"success":0,"failure":1,"canonical_ids":0,"results":[{"error":"MismatchSenderId"}]}
i don't know why because the sender id is right, the api also (i've tried the server key and the browser key, just to be sure).
i really don't know where i get wrong!
in my app i have only the sender id and all have gone right, in my server i've got the key for browser (now):
<?php require_once("../pi_classes/commonSetting.php");
include('../pi_classes/User.php');
ini_set("display_errors",1);
class GCM{
function __construct(){}
public function send_notification($registatoin_ids,$message){
// GOOGLE API KEY
define("GOOGLE_API_KEY","xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx");
$url="https://android.googleapis.com/gcm/send";
$fields=array(
"registration_ids"=>$registatoin_ids,
"data"=>$message,
);
var_dump($fields);
$headers=array(
"Authorization: key=".GOOGLE_API_KEY,
"Content-Type: application/json"
);
$ch=curl_init();
curl_setopt($ch,CURLOPT_URL,$url);
curl_setopt($ch,CURLOPT_POST,true);
curl_setopt($ch,CURLOPT_HTTPHEADER,$headers);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,true);
curl_setopt($ch,CURLOPT_SSL_VERIFYPEER,false);
curl_setopt($ch,CURLOPT_POSTFIELDS,json_encode($fields));
$result=curl_exec($ch);
if($result===FALSE){
die("Curl failed: ".curl_error($ch));
}
curl_close($ch);
echo $result;
}
}
// ======================

$messaggio="Ciao, sono una notifica!";
$pushCounter=0;
$registatoin_ids=array();
$result=mysql_query("SELECT android_regi_id FROM user_details");
while($row=mysql_fetch_array($result)){
$token=$row["android_regi_id"];
if($token!=""){
$registatoin_ids[]=$token;
$pushCounter++;
}
}
if($pushCounter>0){
$gcm=new GCM();
$message=array("price"=>$messaggio);
$result_android=$gcm->send_notification($registatoin_ids,$message);
echo $result_android;
}
I had the same problem.
The solution is use my Project Number instead of API_KEY for the sender_id in the android app. On the server script you have to keep the API_KEY.
You can see your Project Number in the tab "Overview" inside your project on Google Developers Console.
