将项目迁移到androix

Question

在将我的项目迁移到androidx之前，我的google登录按钮可以正常工作。但是在迁移之后，当我单击“登录”按钮时，应用程序崩溃。我经历了许多StackOverflow问题，但未找到任何解决方案。请帮助我。

这是Logcat错误：

  

java.lang.IncompatibleClassChangeError：类'com.google.android.gms.auth.api.signin.internal.SignInHubActivity'在调用'androidx.lifecycle.Lifecycle androidx'时未实现接口'androidx.lifecycle.LifecycleOwner' .lifecycle.LifecycleOwner.getLifecycle（）”（“ androidx.lifecycle.LiveData”的声明出现在/data/app/com.sumanmsoft.forwardz-1/split_lib_dependencies_apk.apk中）
