无法解决 firebase-messaging 和 common - Android

Question

我在构建项目时遇到此错误。

1. 未能解决：firebase-messaging
2. 无法解决：常见

我在 stackoverflow 上没有得到任何解决方案。请检查代码并让我知道问题所在。

将项目导入 Android Studio 后出现此问题。

要解决这个问题，请更改以下代码行：

implementation 'com.google.firebase:firebase-database:11.6.0'
implementation 'com.google.firebase:firebase-auth:11.6.0'
implementation 'com.google.firebase:firebase-core:11.6.0'

到

implementation 'com.google.firebase:firebase-database:16.0.1'
implementation 'com.google.firebase:firebase-auth:16.0.1'
implementation 'com.google.firebase:firebase-core:16.0.0'

为了使用 Firebase Cloud Messaging，您需要添加相应的依赖项。所以也请添加这行新代码：

implementation 'com.google.firebase:firebase-messaging:17.0.0'
