Firebase 数据库需要 Firebase Core 吗? [英] Do I need Firebase Core for Firebase Database?

问题描述

我只使用 Firebase 数据库并且只添加了下一个依赖项:

I use only Firebase Database and I've added only the next dependency:

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

好像没问题

但在编译期间我收到下一个警告

but during compilation I get next warning

警告:应用程序 gradle 文件必须依赖于com.google.firebase:firebase-core 用于 Firebase 服务作为打算.

Warning: The app gradle file must have a dependency on com.google.firebase:firebase-core for Firebase services to work as intended.

我还应该添加 Core 吗?喜欢:

Should I still add Core? like:

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

推荐答案

是的，你现在必须明确列出它:

Yes, you have to explicitly list it now:

更新 - 2018 年 6 月 12 日

Update - June 12, 2018

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.

Your app gradle file now has to explicitly list com.google.firebase:firebase-core as a dependency for Firebase services to work as expected.
