【问题描述】：
我正在构建一个多聊天室应用。在聊天室 Activity 中，我注册的侦听器很少（添加/删除取决于 Activity 是否处于运行状态）。 用户始终处于登录状态（如果未要求退出）。
当用户将应用程序最小化大约 30 分钟并返回时，我注册了所有侦听器，但没有返回任何数据并引发此异常：

可能是什么原因？ 我需要以某种方式刷新令牌吗？
谢谢。
【问题讨论】：
-
这看起来不像是抛出的异常。这是一系列警告信息（注意每一行的“W”）。警告不是错误。您的应用程序到底发生了什么故障？你有代码要分享吗？有什么具体的吗？
-
这会阻止我从注册的侦听器获取数据。这是我在注册时遇到的一个例外。未经身份验证的含义是什么？与刷新和 ID 令牌有关吗？
-
发布了完整的堆栈跟踪。
-
您无需执行任何操作即可刷新令牌。这一切都是自动发生的。确保您的 SDK 都是最新的，如果仍然出现这种情况，请联系 Firebase 支持并提供完整说明以重现问题。 support.google.com/firebase/contact/support
-
好的，谢谢。现在使用最新版本的 Firebase。我会更新的。
