How to determine location of device in Android using IP address

Question

I am developing an Android app. I want to determine the location of the device using its IP address. Where do I start? The links on Google APIs are not conclusive enough. Thanks

Answer 1

There are several web-services, which provides you latitude and longitude value from IP address.

one such is api.ipinfodb.com

for ex, you can latitude and longitude by sending request like

 http://api.ipinfodb.com/v3/ip-city/?key=
               &ip=74.125.45.100&format=json

this returns the data in json format and you can get response in XML by setting format=xml.(you need to register to get your API key).

or you can download database from this and this link.

you can download datasets but u have to constantly update it.
