PMTiles

Starting MapMetrics Android, using PMTiles as a data source is supported. You can prefix your vector tile source with pmtiles:// to load a PMTiles file. The rest of the URL continue with be https:// to load a remote PMTiles file, asset:// to load an asset or file:// to load a local PMTiles file.

Oliver Wipfli has made a style available that combines a Protomaps basemap together with Foursquare POI dataset. It is available in the wipfli/foursquare-os-places-pmtiles repository on GitHub. The style to use is

The neat thing about this style is that it only uses PMTiles vector sources. PMTiles can be hosted with a relatively simple file server (or file hosting service) instead of a more complex specialized tile server.
