Org to ics calendar with location links?

[Eric Abrahamsen <eric@ericabrahamsen.net>]

I've been exporting some agenda files to iCalendar, then uploading them
to my server and getting them into the calendar app on my Android
tablet, by means of Radicale and DAVDroid. It all works fine, though I
wish I were able to get org-caldav working for two-way syncing.

I recently put a LOCATION property on one of my events, and was very
pleased to see that, in the google calendar app, the location was made
clickable and I was given the option of opening the location in OSMand.
I've wanted this for a long time! The only problem now is that I have no
idea how to format the LOCATION property value so that it's recognized
as a valid link. I assume I'd have to get the GPS coordinates and put
them in there... but how?

I guess this is what they call an "intent" in Android land, but I found
it surprisingly difficult to google an answer.

I know this is verging on OT, but if anyone knows how to do this, please
let me know! It would be nice to make a few custom functions for
inputting this kind of information.

Thanks,
Eric
