如何将Amazon Cognito与Android版Google Plus集成?
这是我的第一个问题,所以请温柔一点。作为我大学项目的一部分,我需要开发一个Android应用程序,让我上传文件,并与其他用户共享文件。我是Android编程新手(我看了一些Android初学者视频,开发了一些基本的应用程序以供练习),也是第一次作为开发者使用云计算。我正在使用Amazon Web服务 我已经得到了允许我使用我的谷歌帐户登录的代码,并在登录后显示我的姓名、电子邮件ID和个人资料照片。 我想将它与AmazonCognito集成,这样我就可以获得唯一的id,我可以使用它进一步处理AWS。如何为每个登录应用程序的用户获取唯一密钥 我看了一些教程,但不明白如何将Cognito代码集成到我的代码中 这是我的密码如何将Amazon Cognito与Android版Google Plus集成?,android,amazon-web-services,google-plus,amazon-cognito,credential-providers,Android,Amazon Web Services,Google Plus,Amazon Cognito,Credential Providers,这是我的第一个问题,所以请温柔一点。作为我大学项目的一部分,我需要开发一个Android应用程序,让我上传文件,并与其他用户共享文件。我是Android编程新手(我看了一些Android初学者视频,开发了一些基本的应用程序以供练习),也是第一次作为开发者使用云计算。我正在使用Amazon Web服务 我已经得到了允许我使用我的谷歌帐户登录的代码,并在登录后显示我的姓名、电子邮件ID和个人资料照片。 我想将它与AmazonCognito集成,这样我就可以获得唯一的id,我可以使用它进一步处理AWS
