offline map available as mbtiles

[nordlicht]

It works, many thanks!

There is a remaining bug, though: When I switch from the mbtiles map to e.g. OSM and then back to the mbtiles map again, it does not display anymore and I get an error of this form:

Dec 07, 2020 6:04:03 PM slash.navigation.maps.mapsforge.mbtiles.DatabaseRenderer executeJob
WARNING: Error while rendering job slash.navigation.maps.mapsforge.mbtiles.RendererJob@3e6e2f4: java.sql.SQLException: database connection closed

I tried to replicate this and can confirm the bug, same error lines in the logfile.
