Getting current geo Location of the user

dakshv22

Hey, I am using Unfolding Maps library to integrate the Open Street Maps Provider into my Java Application. What I want is that as the application starts the map directly zooms and points to the current geo Location of the user. So, the main problem I am encountering is to get the Geo Location of the user in processing. Any ideas anyone? Any help as soon as possible will be great.

Thanks!

you can make GET requests to this api to get the long/lat from his ip

you actually need this endpoint http://www.telize.com/geoip

the response is in json format

Thanks for the link. This works pretty well. But I think its accuracy is not that good. The actual location is varying by about 5 kms. What should I do?

maybe search for other geoip services and use the one that seems more accurate.. i do not think that you can get the exact location , i mean dont expect that it will be as accurate as a gps device

So, If I want to develop an android application how can I access the gps service of the phone from my processing application? Is it possible?

Also, does any API exist on which I can query for the longitude and the latitude of a place? The query can be a string consisting of the name/location of the place.

i have not used processing in android a lot so i cannot answer for sure, i assume you can get pgs location by setting appropriate permissions..better wait for someone else answer this

what you need is a geocoding service, like google`s or maybe you can find another provider..try to search in the programmableweb.com

example with the address of Facebook headquarters that i found on line, using curl

└──┤ curl https://maps.googleapis.com/maps/api/geocode/json?address=Menlo+Park
