If tracking is lost the anchors will move.  This is probably related to https://github.com/google-ar/arcore-android-sdk/issues/225\r\n\r\nTo get the best tracking results, one thing to consider is how well ArCore has processed the current area in view.  We typically do not place any objects until at least one plane has been found.  Although there could be more strict requirements than that for object placement.\r\n\r\n"}}
