This project still needs more testing and polish. Use with caution
This is a web application designed to be used with OsmAnd's live tracking feature.
It simply receives GET requests with URL parameters that contain the location information, and then stores it in a DB and serves it on a simple web map.
Authentication is simply through a token that is a URL parameter, and it needs to match the token that was used as an environment variable for the server.
In the settings for the app, select the profile you're going to use, then go to Trip Recording -> Online Tracking.
Enter the following URL, with the domain pointing to where you've hosted the server and the token set to a random value that is also use on the server: https://example.com/log?lat={0}&lon={1}×tamp={2}&hdop={3}&altitude={4}&speed={5}&bearing={6}&token=foobar.
Set the tracking interval to the value you'd like, and then you're ready!
