不推荐使用 GoogleApiClient 与位置一起使用

如何解决不推荐使用 GoogleApiClient 与位置一起使用

所以我是 android java 的新手，也是使用集成到我的应用程序中的 google 服务的新手，我按照在线教程获取用户当前位置并显示附近的地方。但是，它表明 GoogleApiClient 已被弃用，鉴于 https://developers.google.com/android/reference/com/google/android/gms/common/api/GoogleApi 使用基于 GoogleApi 的 API 的文档，我真的不知道如何解决这个问题。

我也不太了解访问谷歌 API https://developers.google.com/android/guides/api-client#java 的文档。我的应用程序可以运行，但它根本不显示地图和当前位置。这是我向 stackoverflow 提出的第一个问题。任何帮助将不胜感激！

这是我的代码：

解决方法

是的，它已经被替换了！
现在你必须使用 GoogleSignInOptions 来访问任何谷歌 API 客户端

GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN).build();
GoogleSignInClient mGoogleSignInClient = GoogleSignIn.getClient(this,so);
GoogleApiClient mGoogleApiClient = mGoogleSignInClient.asGoogleApiClient();
