I used to test it on Nexus 4 (2GB RAM) and now I just moved to OnePlus X (3GB RAM). Since I don't have access to Jolla 1, I have no idea how well it works on that. I have followed the RAM usage of the server using SystemDataScope earlier and it was about 300MB RSS, if I recall correctly.

However, while RAM is handy, it would not have a major impact on map loading, I think (unless its cached by FS). You are probably bound by I/O from SD card, unfortunately.

I was actually quite surprised that the route calculation was successful because OsmAnd had trouble with the length of the route, or the bridge to Skye (maybe it was a map split in OsmAnd?), or both. Not only that, OSM Scout Server was quicker than OsmAnd taking just a couple of minutes. to calculate. So basically, you've beaten the best offline map & routing app for Android already...
No, I don't think we have beaten OsmAnd. Maybe in routing speed, but there is still a long way ahead - keep patches and issues coming!

There are many ways of contributing in addition to coding. For example: filing issues, working on map drawing styles (standard.oss on your phone) and making them better suited for Poor Maps and modRana.

I am wondering, how well does it cope with the wrong-sided roundabouts? Any other problems? Never tested it on UK maps, I must say. Please file issues in GitHub if you see any.

Yes, map.ost is just used for importing. You could actually tweak it to import or exclude the features you want. Although, let us know if you changed it when you stumble on some bugs.

To take the maximal positive out from the current situation, you could even try to memorize UUID while you type it in .

Yes, I plan to add file/directory selection dialogue. Not sure it will be in the next release, but it will come. You could probably use symbolic links for now to simplify the path. Issue filed: https://github.com/rinigus/osmscout-server/issues/42

Will deal with it: https://github.com/rinigus/osmscout-server/issues/41
