The gridState is called each time the location changes. It checks if the location has moved away from the center of the current tile grid and if it has calculates a new grid.

getLocationDescription

fun getLocationDescription(location: LngLatAlt): LocationDescription

getLocationDescription returns a LocationDescription object for the current location. This is basically a reverse geocode. It initially tries to generate it from local tile data, but falls back to geocoding via the Photon server if network is available.

getRecordingShareUri

fun getRecordingShareUri(context: Context): Uri?

myLocation

fun myLocation(): TrackedCallout?

nearbyMarkers

fun nearbyMarkers(): TrackedCallout?

recomputeStreetPreviewBestChoice

fun recomputeStreetPreviewBestChoice(soundscapeService: SoundscapeService)

refreshOfflineMaps

fun refreshOfflineMaps()

Called when the on-disk offline map extracts have changed (a download completed, or an extract was deleted) so that both grids pick up the change on their next location update instead of only opportunistically the next time the user crosses a grid boundary.
