HMS Maps: Optimize the phenomenon of Uber route drift.

[DaVinci9196]

When using Uber, I found that the route information that appeared would drift when I moved the map. I am not sure if it is due to the map, so I will not calculate the route to display during the movement.

@DaVinci9196 It will caused a NullPointException when map destroyed.
when camera move, will postDelay a controlLayerRun, and map onDestroy will set mapView to null, when and it finally crashed on refreshContainerLayer caused you use mapView!!
