How can I get my Android device country code without using GPS

Question

An Android mobile actually does know quite well where it is - but is there a way of retrieving the country by something  like a country code or country name  There isn t any need to know the exact GPS position - the country code or name is sufficient  and I am using this code   String locale   context getResources   getConfiguration   locale getCountry Locale getDefault      System out println  quot country    quot  locale    It gives me the code  quot US quot   but my device kept in India  Is there a way to find the device s current country code without using GPS or a network provider  Because I am using a tablet

If you wish to get the country code without asking for any permission, you can choose a tricky way.

The method simply uses an API to get the country code, and there aren't any third-party libraries to depend on. We can create one for us.

Here I have used Google Cloud Functions to write an API and it is so effortless.

Step 1: Create a Google Cloud Account, and set up billing (the free tier is enough)

Step 2: Create a cloud function to get the geo location

Copy this basic function to the code editor of index.js:

const cors = require('cors')

function _geolocation(req, res) {
  const data = {
    country_code: req.headers["x-appengine-country"],
    region: req.headers["x-appengine-region"],
    city: req.headers["x-appengine-city"],
    cityLatLong: req.headers["x-appengine-citylatlong"],
    userIP: req.headers["x-appengine-user-ip"]
  }

  res.json(data)
};

exports.geolocation = (req, res) => {
  const corsHandler = cors({ origin: true })

  return corsHandler(req, res, function() {
    return _geolocation(req, res);
  });
};

Also we need to copy the package.json definition:

{
  "name": "gfc-geolocation",
  "version": "0.0.1",
  "dependencies": {
    "cors": "^2.8.4"
  }
}

Step 3: finish, and get the URL similar to: "https://us-central1-geolocation-mods-sdde.cloudfunctions.net/geolocation"

Step 4: parse the JSON response and get the country code

The response will look like:

{
   "country": "IN",
   "region": "kl",
   "city": "kochi",
   "cityLatLong": "9.9312,76.2673",
   "userIP": "xx.xx.xx.xx"
}

Use the link http   ip-api com json  This will provide all the information as JSON  From this JSON content you can get the country easily  This site works using your current IP address  It automatically detects the IP address and sendback details  Documentation This is what I got     quot as quot    quot AS55410 C48 Okhla Industrial Estate  New Delhi-110020 quot    quot city quot    quot Kochi quot    quot country quot    quot India quot    quot countryCode quot    quot IN quot    quot isp quot    quot Vodafone India quot    quot lat quot   9 9667   quot lon quot   76 2333   quot org quot    quot Vodafone India quot    quot query quot    quot 123 63 81 162 quot    quot region quot    quot KL quot    quot regionName quot    quot Kerala quot    quot status quot    quot success quot    quot timezone quot    quot Asia Kolkata quot    quot zip quot    quot  quot     N B  - As this is a third-party API  do not use it as the primary solution  And also I am not sure whether it s free or not

For some devices  if the default language is set different  an Indian can set English  US   then context getResources   getConfiguration   locale getDisplayCountry     will give the wrong value  So this method is not reliable  Also  getNetworkCountryIso   method of TelephonyManager will not work on devices which don t have SIM card  Wi-Fi tablets   If a device doesn t have a SIM card then we can use the time zone to get the country  For countries like India  this method will work  Sample code used to check the country is India or not  Use the below values in your constants file  Constants INDIA TIME ZONE ID   quot asia calcutta quot   Constants NETWORK INDIA CODE   quot in quot   And in your activity  add the following code  private void checkCountry          TelephonyManager telMgr    TelephonyManager  getSystemService Context TELEPHONY SERVICE       if  telMgr    null          return       int simState   telMgr getSimState         switch  simState                If a SIM card is not available then the            country is found using the timezone ID         case TelephonyManager SIM STATE ABSENT              TimeZone tz   TimeZone getDefault                String timeZoneId   tz getID                if  timeZoneId equalsIgnoreCase Constants INDIA TIME ZONE ID                       Do something                           else                     Do something                           break              If a SIM card is available then the telephony            manager network country information is used         case TelephonyManager SIM STATE READY               if  telMgr    null                    String countryCodeValue   tm getNetworkCountryIso                        Check if the network country code is  quot in quot                  if  countryCodeValue equalsIgnoreCase Constants NETWORK INDIA CODE                           Do something                                   else                         Do something                                             break

You shouldn t be passing anything in to getCountry    Remove Locale getDefault    String locale   context getResources   getConfiguration   locale getCountry

There isn t any need to call any API  You can get the country code from your device where it is located  Just use this function   fun getUserCountry context  Context   String        try           val tm   context getSystemService Context TELEPHONY SERVICE  as TelephonyManager         val simCountry   tm simCountryIso         if  simCountry    null  amp  amp  simCountry length    2       SIM country code is available             return simCountry toLowerCase Locale US                     else if  tm phoneType    TelephonyManager PHONE TYPE CDMA       Device is not 3G  would be unreliable              val networkCountry   tm networkCountryIso             if  networkCountry    null  amp  amp  networkCountry length    2       network country code is available                 return networkCountry toLowerCase Locale US                                    catch  e  Exception              return null

You can simply use this code  TelephonyManager tm    TelephonyManager this getSystemService Context TELEPHONY SERVICE   String countryCodeValue   tm getNetworkCountryIso     This will return  US  if your current connected network is in the United States  This works without a SIM card even
