Question

我正在将Google登录与我的应用以及androidx集成在一起。因此，我不得不从实现'com.google.android.gms：play-services-auth：16.0.1'中排除支持库。使用以下错误日志崩溃。

googleSignInClient = GoogleSignIn.getClient(context!!, googleSignInOptions)

崩溃日志指向GoogleSignIn.getClient（...）的最后一行。

这为我解决了问题：删除应用程序build.gradle中play-services-auth库上的排除项，然后，如果出现“程序类型不存在...”错误，请将这些行添加到gradle.properties中：

android.useAndroidX = true
android.enableJetifier = true

使用androidx的Android Google登录提供了以下失败的解析：Landroid / support / v4 / util / ArraySet Error
