我正在使用来自这里的谷歌的 friendlychat android 代码:https://codelabs.developers.google.com/codelabs/firebase-android/#0
代码:https://github.com/firebase/friendlychat-android
将聊天应用与 Firebase 连接。在我的安卓模拟器(Pixel 2 XL API 27)中运行良好。可以登录,发送消息。
但每当我在手机(华为 Y5ii;旧设备)中使用该应用程序时,它都会显示登录页面。我点击登录,选择我的电子邮件,但它永远不会打开聊天屏幕。无法弄清楚是什么问题。

最佳答案
正如我们在评论中讨论的那样,我将此添加为任何 future 引用的答案:
应将调试和发布签名证书的 SHA1 签名添加到 firebase 项目中,然后必须在部署前将该 firebase 项目中的 google-services.json 文件添加到应用中。
