In my application I want to use the users' current latitude and longitude. I use the following example.
Still I did not get the answer.
Can emulator displays the latitude and longitude?
How shall i get latitude and longitude from the IP address??
quick response will help me a lot.
There are some different APIs you can use to get a IPs location. This post mentions a few.
Your linked answer uses GPS to get the current position. The Emulator does not have a working GPS-module, so when testing this in the emulator, you can add fake-data for the lat. and long. so you can test the code. More here: How to emulate GPS location in the Android Emulator?
If you want to get a location on an IP-address, you can use certain services for that. This has already been discussed here: What's the simplest way to get a user's latitude and longitude from an ip address
As mentioned in the linked post, I'm not sure about the accuracy of those services.
I dont think there is a possibility to return position data from an IP adress possibly the country but not pin point exact (altitude, longtitude) therefor you need to return device gps data wich is transfered though the internet but has nothing to do with an IP adress..
I have finally found my mistake. the example given HERE works fine.
And the mistake was mine. In the location Setting in my mobile, i forget to check the mobile networks option. once i checked tat option i got the latitude and longitude for my current location.
Try http://www.iptolatlng.com/ , it provides JSON and JSONP results

I have created simple android application which take current Latitude and Longitude from google api. then it will store that data to server.
My problem is that every time when i am try to get the Location it show me different value. same place and same phone then also it fetches different data.
this problem is very critical because i am doing some functionality based on the difference of the Latitude and Longitude.
can you tell me how can i get the same lat and long in each devices ?
Thanks in advance
Does it display huge differences or just ~50-100m differences? Because GPS isn't exact (plus it depends on connections, ...).
I'm looking to implement, real time location tracking for android apps.
The server would request a specific device's real time location which needs to be shown on google map. can anyone help me with this.
Thanks
use geo coding google api to do this stuff.... through gps in android write a android app, that should send latitude and longitude position for every 10 or 20sec so that you can make a variable for latitude and longitude so that new value get updated and stored
I'm new to android programming and I'm wondering if it's possible and how to retrive from the current position (I don't even know how to retrieve it) the region and the province.
Could you please post some code or tell me where I can find it?
Thanks!!!!!!

GPS TRACKING IN ANDROID PHONE:
You can retrieve current location of the mobile phone using Android Location Manager.
Tutorial Reference: GPS Tracking
REVERSE GEOCODING WITH AVAILABLE LAT LONG:
For getting the region and province, after getting current lat/long from phone, you can use the google reverse geocoding API that can be consumed via web-service.
The Google Reverse Geo-coding API is : https://maps.googleapis.com/maps/api/geocode/json?
Usage would be a GET REQUEST like : https://maps.googleapis.com/maps/api/geocode/json?latlng=40.714224,-73.961452
(You won't get a response if you just copy and paste the URL in browser)
(API Key is also not required for limited usage)
Reference : Reverse Geocoding
First, find the location of your user using the Location Manager.
Then, pass the location to Google's Geocoder for the address (it contains the state, province and more)
You can also use the methode of Geocode class's (android.location) : http://developer.android.com/reference/android/location/Geocoder.html
I'm developing an Android app to integrate with another app.
In this app I need get the current user location and send it to the other app.
I'm getting the latiude and longitude using the following web service:
https://maps.googleapis.com/maps/api/geocode/json?address=Rua+Vergueiro,+1883,+S%C3%A3o+Paulo,+Brazil&sensor=true
The problem is that when the other app receive the latitude an longitude and convert it to address description, an wrong address is showed to the user.
The other app is using the here.com web services to convert the latitude and longitude to address description and Im using googleapi.
Anyone knows tell me what may be happening?
Thanks.
You are geocoding using one service (i.e. Google) and reverse geocoding using a second service (i.e. HERE) and the underlying data is different for each one. As it happens, the location you are looking for is at a junction as shown here
If you run a reverse geocoding search for this location, then the closest location found by HERE is around the corner at Rua Jardim Ivone - the second closest result found by HERE is the same as Google - Rua Vergueiro. As you can see from the picture this is correct - the closest house on the map to the stated location given is actually around the corner.
I have some app that sends some information to the internet from time to time let say ones at day. And I can easily send some coordinates (using the gps position) but I do not want that. The android phone is always connected to the internet via wifi or mobile network. But not always enabled the gps. So is it possible to get the location with wifi or mobile network ? I google this thing and I end up with finding location by gps, I do not want to do that.
Can you give me some ideas what can I do this. I have seen web sites that when I open them they know where am I, so I guess it is possible to find the nearest name of the city just by making a internet request and reading the response or maybe use some service . . .
Thanks

getLocality looks like it may do what you want?
For websites that know where you are, they either use your source IP and look that up (which isn't very reliable for a lot of things), or they use the javascript geolocation APIs as described here:
