Using the Google API javascript in Cordova / Phonegap

Question

I'm developing an application with Cordova and would like to save files in Googe Drive.

I've got success in login to Google, using the cordova-plugin-googleplus (https://github.com/EddyVerbruggen/cordova-plugin-googleplus). However I could not get the plugin returns to me accessToken or idToken so I could use with Google javascript API.

window.plugins.googleplus.login(
    {
        'scopes': 'https://www.googleapis.com/auth/drive.file profile',
        'offline': true, 
        'webApiKey': ‘CODE’ 
    },
    function (obj) {
        $scope.$apply(function() {
            $scope.srcImage = obj.imageUrl;
            $scope.NomeGoogle = obj.displayName;
        });
    },
    function (msg) {
        alert('Erro');
        alert('error: ' + msg);
    }
);

I tried using the code below, but returned me the following error:

"Uncaught gapi.auth2.ExternallyVisibleError: Invalid cookiePolicy"

gapi.load('auth2', function() {

    gapi.auth2.init({

        client_id: 'REVERSED_CLIENTID',

    }).then(function(){

        auth2 = gapi.auth2.getAuthInstance();
        console.log(auth2.isSignedIn.get()); //now this always returns correctly        

    });
});

I managed to figure out the problem, why wasn´t getting the serverAuthCode from plugin. It is necessary to create 2 credentials on the Google Developers Console. The 1st must be Android, this will be for the plugin and the 2nd should be a Web App, this is necessary to achieve serverAuthCode.

The code looks like this

window.plugins.googleplus.login(
    {
        'scopes': 'https://www.googleapis.com/auth/drive.file profile',
        'offline': true, 
        'webApiKey': ‘REVERSED_CODE of Web App Credential’ 
    },
    function (obj) {
        $scope.$apply(function() {
            $scope.srcImage = obj.imageUrl;
            $scope.NomeGoogle = obj.displayName;
        });


            var data = $.param({
                client_id: 'REVERSED_CODE of Web App Credential',
                client_secret: 'SECRET_CODE of Web App Credential',
                grant_type: 'authorization_code',
                code: obj.serverAuthCode
            });

            var config = {
                headers : {
                    'Content-Type': 'application/x-www-form-urlencoded;charset=utf-8;'
                }
            }

            $http.post("https://www.googleapis.com/oauth2/v3/token", data, config).success(function(data, status) {
                //data.access_token;

/** from now you can do use of google API **/

            })
            .error(function(data, status) {
                console.log(data);
                console.log(status);
            });

    },
    function (msg) {
        alert('Erro');
        alert('error: ' + msg);
    }
);
