Google登录无法在Real Device中运行

我正在从这里使用Google的friendlychat android代码：https：//codelabs.developers.google.com/codelabs/firebase-android/#0

代码：https：//github.com/firebase/friendlychat-android

将聊天应用程序连接到了Firebase。在我的android模拟器（Pixel 2 XL API 27）中工作正常。可以登录，发送消息。

但是每当我在手机（Huawei Y5ii；旧设备）中使用该应用程序时，它就会显示登录页面。我单击登录，选择我的电子邮件，但它从未打开过聊天屏幕。无法找出问题所在。
