Android Geocoder

[papjul]

Native reverse geocoding source

Must check if a backend exists first:

Even if available, it's not guaranteed to have a result, so a fallback to Natural Earth is still necessary.

It's not yet decided if it will be included in the freenet flavor. While a manufacturer could technically put a free and open source geocoder backend, it's reasonable to think that almost all devices will have either Google geocoding backend or no backend. It's similar to network location provider which relies on Google API as well, however the user has a way to turn it off in settings, so we only rely on GPS hardware.
