Question

重现问题的步骤如下：

单击 google 登录按钮。
选择"use another account"
使用新帐户登录，这会让您返回应用程序。
应用程序只显示深色覆盖和同意书或回调（到 onActivityResult）不起作用。

然后，如果我触摸屏幕，深色覆盖就会消失，此时如果我再次按下 google 按钮，它会自动让我登录该帐户。我尝试了一些应用程序，如 Whosebug、traveloka、airBNB、我自己的带有 google SSO 按钮和 glassdoor、lazada 等的简单应用程序，以及其他一些应用程序，在进入选项 3 后它们都给出了错误。

我想也许是 [oauth 同意书]：

我填写了它，但我只请求电子邮件作为 google SSO 选项。所以我填写了表格，但等了一会儿什么也没填。

如果您想查看我的完整代码，它非常标准 google SSO 按钮 and its here： class 被称为 LoginFragment.kt

但让我 post 这里 class 处理登录：

我做错了什么？这是一个 google 错误吗？如果可能的话，我什至会选择一种方法来禁用选择器上的这个选项。

我的测试是在 api 24

完成的

来自 firebase ui 团队 - https://github.com/firebase/FirebaseUI-Android/issues/1297。我看到这是一个已知问题，将在下一个 google 播放服务版本中修复。

android - google SSO 选择器 - 使用另一个不提供回调的帐户选项

android - google SSO chooser - Use another account option not giving callback

google-authentication

google-api-client
