Мое приложение аварийно завершает работу, когда вызывается MapController.animateTo и происходит какое-либо событие касания, пока анимация все еще выполняется. Это урезанная версия того, что я делаю. Но этот код также аварийно завершает работу. Сначала я подумал, что это метод mLocationOverlay.runOnFirstFix. Но я обнаружил, что могу позвонить ему куда угодно, и он все равно вылетит с исключением NullPointerException

 val ctx = applicationContext  Configuration.getInstance().load(ctx, PreferenceManager.getDefaultSharedPreferences(ctx))    map = findViewByIdlt;Viewgt;(R.id.map) as MapView  map.setTileSource(TileSourceFactory.DEFAULT_TILE_SOURCE)  mapController = MapController(map)   mLocationOverlay = MyLocationNewOverlay(GpsMyLocationProvider(this), map)  mLocationOverlay.enableMyLocation()  mLocationOverlay.runOnFirstFix {  runOnUiThread {  mapController.animateTo(mLocationOverlay.myLocation, 14.0, 4000)  }  }  map.overlays.add(mLocationOverlay)

Конечно, как только я задам этот вопрос, я все пойму.

 mLocationOverlay.runOnFirstFix {  runOnUiThread {  mapView.controller.animateTo(mLocationOverlay.myLocation, 14.0, 4000)  //mapController.animateTo(mLocationOverlay.myLocation, 14.0, 4000)  }  }  

Я должен вызвать метод animateTo через MapView, а не пытаться вызвать его напрямую из MapController
