Question

在出现此错误之前，我将firebase-auth更新到版本16.0.2，以解决“程序类型已存在：com.google.android.gms.internal”错误。会相关吗？

Answer 1

我升级到4.2.0，并且可以正常工作

classpath 'com.google.gms:google-services:4.2.0'

Answer 2

您对firebase-database的依赖确实很老。尝试使用最新版本：

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

每个依赖项的最新版本均为listed on this page。
