Yeah right
I have Osmand+ and it works fine. One very easy way to improve the performance is to download the maps you need ahead of time.
Start by downloading your metro area and I can guarantee that positioning and navigation will be instantaneous. Unless your phone is to blame. FYI I am using a Google Nexus 7a. Very happy with Osmand+.
Please keep in mind I haven’t done any work on either for a few years now. I would definitely check if something is possible today… But with little hope. AWS support should be able to give you more infos on this connection (or lack thereof).
Worked on both AWS and GovCloud for a while, and there was NO communication between the two at the time.
GovCloud was its own thing, completely separate from regular AWS.
There is a guy named Arthur David Olson who maintains a small database of all the time zones in the world, including things like leap seconds and such. It’s used by everybody and it is updated several times a year. See here:
