我在我的项目中添加了 firebase crashlytics 依赖项，之后项目没有构建。

https://firebase.google.com/docs/crashlytics/get-started?authuser=0&platform=android#android

请问我可能做错了什么。

谢谢 R

构建在这些行上失败

implementation "com.google.android.gms:play-services-base:17.0.0"
implementation 'com.google.firebase:firebase-core:17.0.0'

这是错误日志

最佳答案

问题是最新的 firebase 依赖项已迁移到 androidx。所以一个修复是将您的项目迁移到 androidx，请参阅 migrate to androidx (我更喜欢，因为所有新升级都使用 androidx)。或者你可以将 firebase-core 依赖降级到以下版本

implementation 'com.google.firebase:firebase-core:16.0.9'
