How can I get a user's country location?

Due to GDPR, I am requiring to check the user's location - whether the user is from the European Union. Till now I have found these solutions -

  1. Get Country using the Phone's language configuration (can misguide if the user uses English US version even though he might be from some other country).

     String locale = context.getResources().getConfiguration().locale.getCountry();

  2. Get Location using the GPS (requires the location coarse permission which I do not want to add especially because of Android 6.0+ runtime permissions).

     private void getCountryCode(final Location location) {
     Helper.log(TAG, "getCountryCode");

     AsyncTask<Void, Void, String> countryCodeTask = new AsyncTask<Void, Void, String>() {

         final float latitude = (float) location.getLatitude();
         final float longitude = (float) location.getLongitude();
         // Helper.log(TAG, "latitude: " + latitude);
         List<Address> addresses = null;
         Geocoder gcd = new Geocoder(mContext);
         String code = null;

         @Override
         protected String doInBackground(Void... params) {
             try {
                 addresses = gcd.getFromLocation(latitude, longitude, 1);
                 code = addresses.get(0).getCountryCode();
             } 
             catch (IOException e) {
                 e.printStackTrace();
             }
             return code;
         }

         @Override
         protected void onPostExecute(String code) {
             Helper.log(TAG, "onPostExecute");
             mCountryCodeListener.returnCountryCode(code);
         }
     };

     if (Build.VERSION.SDK_INT <= Build.VERSION_CODES.GINGERBREAD_MR1) {
         countryCodeTask.execute();
     }
     else {
         countryCodeTask.executeOnExecutor(AsyncTask.THREAD_POOL_EXECUTOR);
     }
 }

  3. Get Location using the SIM card or Wi-Fi (can not be used on tables without SIM card or Wi-Fi, whereas my app can be used on the device without an Internet connection or Wi-Fi).

     TelephonyManager tm = (TelephonyManager)this.getSystemService(Context.TELEPHONY_SERVICE);
 String countryCodeValue = tm.getNetworkCountryIso();

Is it possible to find out the location of the user if the user is from European Union region or not?

I do not need the exact location and even the country will work.

Is there another method which might also require location permission (not the coarse location permission will also be helpful)?

Please note that this question is not a duplicate of any other question as my case is not being solved by any other question.

Another method to do it is tracking IP location, but this may not work if the user uses VPN or proxy.

Here is an exemple of IP location api service : https://ip-api.com/

Use the Google Consent SDK to check if the user is in the European Economic Area (EEA).

In build.gradle, add:

implementation 'com.google.android.ads.consent:consent-library:1.0.6'

Use ConsentInformation.getInstance(context).requestConsentInfoUpdate( ... ) as described in the documentation.

Then use:

ConsentInformation.getInstance(context).isRequestLocationInEeaOrUnknown()

If the function returns true, apply GDPR rules to your app.

If you don't have GPS functionality in your app and you want to add and use it just for this case, it affects the user experience and I would suggest that you should assume that the user is already in that region and do what you have to do.

Getting the location (and draining the battery) just for this case is an overkill.

You can fetch MCC/MNC code and as your interest is in country MCC (mobile country code) should suffice.

You have mentioned all the possible options to get Country Name, but there is one more option. If your application has permission to access the Internet, you can get country name by IP address as well...

You can get the country name from the IP address as well. Once you have an IP address, pass that to the ipstack API to get the country name. You can make 10,000 requests/month for free.

There are many different ways to get an IP address (google it). One way is below:

public static String getLocalIpAddress() {
    try {
        for (Enumeration<NetworkInterface> en = NetworkInterface.getNetworkInterfaces(); en.hasMoreElements();) {
            NetworkInterface intf = en.nextElement();
            for (Enumeration<InetAddress> enumIpAddr = intf.getInetAddresses(); enumIpAddr.hasMoreElements();) {
                InetAddress inetAddress = enumIpAddr.nextElement();
                if (!inetAddress.isLoopbackAddress() && inetAddress instanceof Inet4Address) {
                    return inetAddress.getHostAddress();
                }
            }
        }
    } catch (SocketException ex) {
        ex.printStackTrace();
    }
    return null;
}

Add the below permission to AndroidManifest.xml:

 <uses-permission android:name="android.permission.INTERNET" />
 <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

Checkout this documentation for how to use the ipstack API: https://ipstack.com/documentation.

Usage:

https://api.ipstack.com/YOUR_IP_ADDRESS?access_key=YOUR_ACCESS_KEY

API response for 134.201.250.155 IP address in JSON format (you can get it in XML as well if you want):

You can check if user is in the EU by requesting the URL http://adservice.google.com/getconfig/pubvendors. It gives you an answer like this:

{"is_request_in_eea_or_unknown":true}

Somewhere I've read that it is the way the Android consent SDK works.
