android - java.lang.ClassNotFoundException : com. google.android.gms.common.GoogleApiAvailability 尝试将 arcore 与 mediapipe 集成时发生

Question

我正在努力集成 arcore 和 mediapipe 应用程序。但是当我尝试在 mediapipe 源代码中集成 arcore 时，我遇到了 session 对象的问题，如下所示。

尝试创建 ARCore 的 session 对象时遇到以下问题

我通过添加以下依赖项解决了这个问题。这个问题是由于 AR Session 依赖于以下依赖项引起的

com.google.android.gms:play-services-auth:17.
