模型不在我的arcore应用程序中呈现吗？

Question

E / ACameraMetadata：getConstEntry：找不到元数据标记65578 E / ACameraMetadata：getConstEntry：找不到元数据标记65578 E / native：hit_test.cc:381generic::internal：没有命中点。 I / native：performance_monitor.cc:115事件：FeatureExtraction花费的时间太长，花费了118.033ms W / native：motion_tracking_context.cc：838generic :: failed_precondition：调用了GetFeatureTracks，但FeatureTracks不可用。

检测到平面，也将模型放置在平面上，但是当我单击“动画”按钮时，它就不会动画。
