geolocation

I am developing a small android application in which I want to have Geolocation functionality. What I want to code is one service which gives the updated location of a user whether they are using my application or not. I know that if I am continuously checking the user's location it will drain the battery of the device, so I want good solution for that. For example, to give me updates every 5 or 10 minutes. I have read about this question a lot but I wanted to get one good solution. I read this page and it's a good solution if the user is using my application but if the user not using my

Is there a way getting all countries, states,cities zipcodes/ in one single database. I have been looking all over. I discovered geonames.org , which has I guess all of the content. But there is no way to fetch that data directly. I am using rails. If there any helpers or Plugins, it'd be great. It would be awesome if there is a complete resource in any parsable format which I can use to get this database in place. Please recommend if you any thanks I do have the iso country code list but no States for some countries. Thanks in advance Thanks Guys, I got all the the countries and states of all

In PHP, I have the following code for calculating the distance between two locations: <?php function distance($lat1, $long1, $lat2, $long2) { // DEGREE TO RADIAN $latitude1 = $lat1/180*pi(); $longitude1 = $long1/180*pi(); $latitude2 = $lat2/180*pi(); $longitude2 = $long2/180*pi(); // FORMULA: e = ARCCOS ( SIN(Latitude1) * SIN(Latitude2) + COS(Latitude1) * COS(Latitude2) * COS(Longitude2-Longitude1) ) * EARTH_RADIUS $distance = acos(sin($latitude1)*sin($latitude2)+cos($latitude1)*cos($latitude2)*cos($longitude2-$longitude1))*6371; return $distance; } echo distance(9.9921962, 53.5534074, 9

I just want to get latitude & longitude using the post code with Google maps API. I am using PHP for development. How can I do this? The post code can be from any where in this world. You can do this using google map Geocoding API. Please find below example, but to correct latitude/longitude and address you need to pass full address along with zipcode. For more detail please click on below link: http://code.google.com/apis/maps/documentation/geocoding/ <?php $url ="http://maps.googleapis.com/maps/api/geocode/xml?address=1600+Amphitheatre+Parkway,+Mountain+View,+CA&sensor=false"; $result =

I'm having a trouble to get Geolocation working on Android in both emulator (even when I geo fix over telnet) and on device. Works on iOS, WP8 and in the browser. When I ask device for location using the following code, I always get an error (in my case custom Retrieving your position failed for unknown reason. with null both error code and error message). Related code: successHandler = (position) -> resolve App.Location.create lat: position.coords.latitude lng: position.coords.longitude errorHandler = (error) -> error = switch error.code when 1 App.LocationError.create message: 'You haven\'t

Explanation/Scenario: I am developing a app that needs to get in real-time(like 3sec's update) the location of all users of mine app, and these users knowing that, too, will see the another users location, in a map, for example: This location, needs to be in real-time, because all of the users have access to the map, they need to know where are the users of the app, in the exact moment, to find them selves. Question: What i need to do to make my application get in real time the location of all of the users in gps coordinates( for later use on the map )? Obs: I am not asking a full application,
