我试图通过Google plus在我的应用程序登录，但是我得到非常奇怪的错误，我几乎到处都在搜索，一切都是一样的，但没有运气。下面是我的代码，其中实现是完成的。日志显示系统错误java.lang.IllegalArgumentException: GoogleApiClient参数是必需的

您从未将mGoogleApiClient设置为任何值。
这取代了旧的PlusClient/GamesClient/AppStateClient/等。客户。您创建一个GoogleApiClient并将其传递给任何API方法。
如果你有mPlusClient = ...你想用
mGoogleApiClient = new GoogleApiClient.Builder()
.addApi(Plus.API, new Plus.PlusOptions.Builder()
.addActivityTypes(
"http://schemas.google.com/AddActivity",
"http://schemas.google.com/BuyActivity")
.build())
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
.build()
删除mPlusClient，使用mGoogleApiClient
