Android：客户端尚未准备就绪。正在等待流程上线

我收到以下错误；每当我尝试启动该应用程序时，它就会崩溃。
我已经使用模拟器和移动设备尝试了几次，但是仍然无法正常工作。

I am getting the error below; whenever I try to launch the app it crashes. I have tried a few times using an emulator and also using my mobile, but it still doesn't work.

我正在使用Firebase身份验证和数据库在项目中。尽管没有错误，但我想知道它是否对错误有影响吗？

I'm using Firebase auth and database in the project. Although there are no errors, I wonder if it has any affect on the error?

$ adb shell am start -n "com.example.juice.health/com.example.juice.health.MainActivity" -a android.intent.action.MAIN -c android.intent.category.LAUNCHER
