I want to use "Login with Google" in my Phonegap App. I have read many articles but couldn't find out how it is done. Thanks in Advance. I tried using oAuth2 for "installed Applications" as per this URL. But then the app users have to manually copy code and paste in my app. I am using built.io Federated Login, if its relevant.
我想在我的Phonegap应用程序中使用“Login with Google”。我读了很多文章但却无法知道它是如何完成的。提前致谢。我尝试按照此URL使用oAuth2作为“已安装的应用程序”。但随后应用用户必须手动并粘贴到我的应用中。我正在使用built.io联合登录，如果它相关。

add this code in one js file and include in your project. when you want to access google login api on button click call function callGoogle() rest will be done by this code. Dont forget to add your client id and Client_Secret keys. Its working fine for me. You need inappbrowser cordova plugin.
将此代码添加到一个js文件中并包含在您的项目中。当你想访问谷歌登录api按钮点击通话功能调用谷歌（）休息将由此代码完成。别忘了添加您的客户端ID和Client_Secret密钥。它对我来说很好。你需要inappbrowser cordova插件。
var googleapi = {
authorize: function(options) {
var deferred = $.Deferred();
//Build the OAuth consent page URL
var authUrl = 'https://accounts.google.com/o/oauth2/auth?' + $.param({
client_id: options.client_id,
redirect_uri: options.redirect_uri,
response_type: 'code',

//Open the OAuth consent page in the InAppBrowser
var authWindow = window.open(authUrl, '_blank', 'location=no,toolbar=no');
//The recommendation is to use the redirect_uri "urn:ietf:wg:oauth:2.0:oob"
//which sets the authorization code in the browser's title. However, we can't
//access the title of the InAppBrowser.
//
//Instead, we pass a bogus redirect_uri of "http://localhost", which means the
//authorization code will get set in the url. We can access the url in the
//loadstart and loadstop events. So if we bind the loadstart event, we can
//find the authorization code and close the InAppBrowser after the user
//has granted us access to their data.
$(authWindow).on('loadstart', function(e) {
