"The geocoder class requires a backend service that is not supported in the core Android framework. The geocoder query methods will return an empty list if there no backend service in the platform."
Here we have mentioned that we need to have a backend service, but we have some suggestions on how to get this service. Some people in the Forum think we should use Google map API.In the following two links, for

Quick query of geographic locationThe Geocoder component provides a quick, geographically-based query that can be queried to display the geographic location of a map by entering an address by adding a query input box. Using Geocoder to move the map display to the specified location area is faster than panning and blooming maps. This feature requires the use of the locator service (location services).Prerequ
Parse maps longitude and latitude using JSON in Android
This error occurs when you use geocoder in googlemaps to reverse the longitude and latitude of a geographical location,"The service is not available" geocoder returns the list as null, and the street information is not obtained. In fact, there has been a bug in the getcoder reversal of latitude and longitude in googlemaps. Google terminated the servic
How to use Python to implement geocoding take the logistics industry as an example. This paper analyzes the logistics industry application methods of PostgreSQL and Greenplum in terms of geographical location information processing, optimal path algorithm, and machine learning. I mentioned the problem of converting addresses into Coordinates. the more professional term should be "geographic code", that is, knowing an address, such as No. 10, Shangdi 1
