All Implemented Interfaces:

IMapTileProviderCallback, MapTileContainer

public class MapTileProviderBasic
extends MapTileProviderArray
implements IMapTileProviderCallback

This top-level tile provider implements a basic tile request chain which includes a MapTileFilesystemProvider (a file-system cache), a MapTileFileArchiveProvider (archive provider), and a MapTileDownloader (downloads map tiles via tile source). Behavior change since osmdroid 5.3: If the device is less than API 10, the file system based cache and writer are used otherwise, the sqlite based
