每次尝试在模拟器上运行我的React Native应用程序时都会遇到此错误（通过Logcat出错）：

我运行react-native run-android时，应用程序成功构建。
我正在使用Firebase，我假设这一定是版本冲突，但是我无法解决任何问题。有什么想法吗？

我四处张望，但找不到关于InternalAuthProvider或失败原因的任何信息。有什么想法吗？
答案 0 :(得分：1)
在这里，firebase auth版本存在问题。
请用implementation('com.google.firebase:firebase-auth:17.0.0')替换implementation('com.google.firebase:firebase-auth:16.0.4')
