android - com.google.android.gms.common.internal.zzf 类型被引用为 > 接口(interface)

Question

我将我的 android 应用程序迁移到 AndroidX(从菜单 Refactor-> 迁移到 androidX)，现在当我运行应用程序时它工作正常，但是当我尝试生成签名的 .apk 文件时，我收到一个错误，例如

Type com.google.android.gms.common.internal.zzf is referenced as an interface from com.google.android.gms.internal.zzcdb.

Type com.google.android.gms.common.internal.zzf is referenced as an interface from com.google.android.gms.internal.zzii.

Type com.google.android.gms.common.internal.zzf is referenced as an interface from com.google.android.gms.internal.zzcms.

这是我在应用程序中使用的依赖项列表，

    }

}

Answer 1

这可能是您的问题的原因:

implementation 'com.google.android.gms:play-services:12.0.1'

其实这个依赖是非常过时了。实际上，您应该将其完全删除，然后让 firebase-messaging 只接收它需要的内容。

如果您需要使用任何特定的播放服务库，您应该使用此处列出的新的、更细化的库之一:
