signInWithEmailAndPassword 调用，但没有为
返回任何callback或addOnFailureListeneraddOnCompleteListener
我在做什么错？？

答案 0 :(得分：0)
要解决此问题，请在您的build.gradle文件中添加以下依赖项：
implementation 'com.google.firebase:firebase-core:16.0.1'
摘自官方文档：
您的应用gradle文件现在必须明确列出
com.google.firebase:firebase-core作为Firebase服务按预期工作的依赖项。
也不要忘记在顶级build.gradle文件中添加以下Google服务插件：
classpath 'com.google.gms:google-services:4.0.2'
