Google API client: "{" error ":" invalid_grant "," error_description ":" Invalid token type. "}"

I am developing an android app using google plus login. When the user tries to log in, I post the token to the server and validate it using the Google APIs using the official Official Google API Client Library for PHP

An error occurred while trying to authenticate the access token, so I debug it and log the response to the request result:

object(Google_Http_Request)#5 (14) { ["batchHeaders":"Google_Http_Request":private]=> array(3) { ["Content-Type"]=> string(16) "application/http" ["Content-Transfer-Encoding"]=> string(6) "binary" ["MIME-Version"]=> string(3) "1.0" } ["queryParams":protected]=> array(0) { } ["requestMethod":protected]=> string(4) "POST" ["requestHeaders":protected]=> array(2) { ["content-type"]=> string(33) "application/x-www-form-urlencoded" ["content-length"]=> int(254) } ["baseComponent":protected]=> string(27) "https://accounts.google.com" ["path":protected]=> string(15) "/o/oauth2/token" ["postBody":protected]=> string(254) "code=ya29.2QAkG7lKto3jZk-6ASgU0MUw_Wy7MdecJTudTkHC4D_XXXXXXFoDHct7C1g&grant_type=authorization_code&redirect_uri=&client_id=547769313690-XXXX.apps.googleusercontent.com&client_secret=hmOBOZk6EDJo-HVq4AMaIUwY" ["userAgent":protected]=> string(0) "" ["canGzip":protected]=> bool(false) ["responseHttpCode":protected]=> int(400) ["responseHeaders":protected]=> array(11) { ["content-type"]=> string(16) "application/json" ["cache-control"]=> string(46) "no-cache, no-store, max-age=0, must-revalidate" ["pragma"]=> string(8) "no-cache" ["expires"]=> string(29) "Fri, 01 Jan 1990 00:00:00 GMT" ["date"]=> string(29) "Thu, 11 Dec 2014 11:53:39 GMT" ["x-content-type-options"]=> string(7) "nosniff" ["x-frame-options"]=> string(10) "SAMEORIGIN" ["x-xss-protection"]=> string(13) "1; mode=block" ["server"]=> string(3) "GSE" ["alternate-protocol"]=> string(15) "443:quic,p=0.02" ["transfer-encoding"]=> string(7) "chunked" } ["responseBody":protected]=> string(80) "{ "error" : "invalid_grant", "error_description" : "Incorrect token type." }" ["expectedClass":protected]=> NULL ["accessKey"]=> NULL } 

      

        
        
        
      

    

and here is my PHP code:

<?php
    $google_client_id       = 'XXX.apps.googleusercontent.com';
    $google_client_secret   = 'XXX-HVq4AMaIUwY';
    $google_redirect_url    = 'xxx';
    $google_developer_key   = 'XXXXXXXXX';
    $google_application_name = 'XXX Login';
    $google_application_scope = 'https://www.googleapis.com/auth/plus.me'; /* I only needed the basic user info */
    $google_redirect_uri='';
    //include google api files
    require_once 'vendor/autoload.php';

    $gClient = new Google_Client();
    $gClient->setApplicationName($google_application_name);
    $gClient->setClientId($google_client_id);
    $gClient->setClientSecret($google_client_secret);
    //$gClient->setRedirectUri($google_redirect_uri);
    $gClient->setScopes($google_application_scope);
   // $gClient->setDeveloperKey($google_developer_key);
    //$gClient->setAccessType('offline');

  $gClient->authenticate("ya29.2QAkG7lKto3jZk-6ASgU0MUw_Wy7MdecJTudTkHC4D_XXXXXX");

  $token = json_decode($gClient->getAccessToken());

    $google_oauthV2 = new Google_Service_Oauth2($gClient);
   $user_info = $google_oauthV2->userinfo->get();
   var_dump($user_info);
    die();
