Where am I - Get country

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   No need of knowing the exact GPS position - the country is sufficient   I first thought of using the time zone  but actually I need more information than that since it makes a difference if the location is New York or Lima   The background of the question  I have an application that uses temperature values  and I d like to set the default unit either to Celsius or Fahrenheit  depending on whether the location is US or outside

You could use getNetworkCountryIso   from TelephonyManager to get the country the phone is currently in  although apparently this is unreliable on CDMA networks

Actually I just found out that there is even one more way of getting a country code  using the getSimCountryIso   method of TelephoneManager   TelephonyManager tm    TelephonyManager getSystemService Context TELEPHONY SERVICE   String countryCode   tm getSimCountryIso      Since it is the sim code it also should not change when traveling to other countries

First  get the LocationManager  Then  call LocationManager getLastKnownPosition  Then create a GeoCoder and call GeoCoder getFromLocation  Do this is in a separate thread   This will give you a list of Address objects  Call Address getCountryName and you got it   Keep in mind that the last known position can be a bit stale  so if the user just crossed the border  you may not know about it for a while

String locale   context getResources   getConfiguration   locale getCountry       Is deprecated  Use this instead   Locale locale  if  Build VERSION SDK INT  gt   Build VERSION CODES N        locale   context getResources   getConfiguration   getLocales   get 0     else       locale   context getResources   getConfiguration   locale

Using GPS with latitude and longitude  we can get the Country code   If we use telephony  it won t work if we are not using sim card and in locale  based on language  it show the country code in wrong

For some devices  if the default language is set different   an indian can set English  US   then   context getResources   getConfiguration   locale getDisplayCountry      will give wrong value  So this method is non reliable  Also  getNetworkCountryIso   method of TelephonyManager will not work on devices which don t have SIM card  WIFI tablets    If a device doesn t have SIM then we can use 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   Time zone id   asia calcutta   private void checkCountry           TelephonyManager telMgr    TelephonyManager  getSystemService Context TELEPHONY SERVICE       if  telMgr    null          return       int simState   telMgr getSimState         switch  simState              if sim is not available then country is find out using 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 sim is available then telephony manager network country info is used         case TelephonyManager SIM STATE READY              TelephonyManager tm    TelephonyManager  this getSystemService Context TELEPHONY SERVICE               if  tm    null                    String countryCodeValue   tm getNetworkCountryIso                      check if the network country code is  in                  if  countryCodeValue equalsIgnoreCase Constants NETWORK INDIA CODE                          do something                                    else                        do something                                              break

This will get the country code set for the phone  phones language  NOT user location     String locale   context getResources   getConfiguration   locale getCountry       can also replace getCountry   with getISO3Country   to get a 3 letter ISO code for the country  This will get the country name    String locale   context getResources   getConfiguration   locale getDisplayCountry      This seems easier than the other methods and rely upon the localisation settings on the phone  so if a US user is abroad they probably still want Fahrenheit and this will work      Editors note  This solution has nothing to do with the location of the phone  It is constant  When you travel to Germany locale will NOT change  In short  locale    location
