I have developped an app with the feature to download a local Map. I'm using the EstimateTileCacheSizeJob to calculate the number of tiles to download. I use the class ExportTileCache to download the tiles. If the map has many tiles the download-time is really long. How can I get the information how many tiles have already been downloaded during the download process. With this information I could show a progressbar how many percent of the download has been done.
