我正在尝试从我的应用程序中使用 Google+ 登录。一切正常，但我遇到了一个白点，就像一个空的警报对话框。

Answer 1

请引用以下链接，了解 Google 与我们应用程序的集成。 https://developers.google.com/identity/sign-in/android/start-integrating

需要记住的几个步骤如下: 1) 单击 https://developers.google.com/identity/sign-in/android/start-integrating 中的生成配置按钮生成 google-service.json 文件

2) 复制google-service.json文件到应用的app文件夹

3) 仔细按照开发者链接的步骤

有代码截图引用:

   @Override

    super.onCreate(savedInstanceState);

    GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
                    .requestEmail()
                    .build();
            // Build a GoogleApiClient with access to the Google Sign-In API and the
    // options specified by gso.
            mGoogleApiClient = new GoogleApiClient.Builder(this)
                    .enableAutoManage(this, this)
                    .addApi(Auth.GOOGLE_SIGN_IN_API, gso)
