我正在努力集成arcore和mediapipe应用程序，但是当我尝试将arcore集成到mediapipe源代码中时，会话对象出现问题，如下所示。
尝试创建ARCore的Session对象时遇到以下问题

最佳答案
我通过添加以下依赖关系解决了此问题。此问题是由于AR Session依赖于以下依赖关系引起的
com.google.android.gms：play-services-auth：17。
关于android - java.lang.ClassNotFoundException:com.google.android.gms.common.GoogleApiAvailability在尝试将arcore与mediapipe集成时发生，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/59435421/
