Answer 1

错误是（根据图片）：

无法解决：com.google.firebase：firebase-database：16.0.3

要解决此问题，请为16.0.1使用firebase-database版，因为它是最新版本。

implementation 'com.google.firebase:firebase-database:16.0.1'

您可以检查here以获得最新版本。

Answer 2

只需以这种方式添加库

implementation 'com.google.firebase:firebase-core:16.0.3'
implementation 'com.google.firebase:firebase-database:16.0.3'
implementation 'com.google.firebase:firebase-auth:16.0.3'

您必须将指令“ 编译”更改为“ 实现”

resove com.google.firebase：firebase-core：16.0.3中显示的错误
