android - 使用 Ar 核心时出现定位服务错误

Question

我有一个 Ar 对象，它放置在屏幕底部，并且会随着相机的移动而移动，但一段时间后会出现错误提示
E/ARCore-LocationProvider:FLP api客户端构建时出现异常:com.google.android.gms.common.api.GoogleApiClient
java.lang.ClassNotFoundException: com.google.android.gms.common.api.GoogleApiClient

我不知道为什么会这样，因为我没有使用任何基于位置的服务

这是完整的错误:

我对 LocationProvider 有类似的问题，我没有在我的应用程序中使用位置。意外地将图像添加到增强图像数据库中时，我使用的名称为空。

AugmentedImageDatabase augmentedImageDatabase = new AugmentedImageDatabase(session);
augmentedImageDatabase.addImage(name /*was null*/, bitmap, size);
