It’d be awesome to have an Android app which could sync to Nextcloud for location tracking. Similar apps to this that already exist are Google+ / location tracking, Geozilla and Life360 family tracker.
There would already be available open source “modules” to use, like Traccar and the osmand format:
Also Vitaly Litvak’s UI extension:
So basically I’d want a client for android like others have done, which could be done as a web-wrapper of Traccar with added features, like easily tracking other Nextcloud users. Perhaps this could be made to work with federation? The tracker part would need a feature where it’d only update the location when the user is moving some distance (much like G+ and Geozilla etc). Of course you could have the option for live tracking, public sharing etc…
From what I see there wouldn’t be that much to program if working with the existing applications in the background. “Really” all that would be needed is the user implementation with Nextcloud and properly implemented android application that would also support wifi / mobile network locating via the Google Maps geolocation API
Open to any further suggestions
