[android-security-discuss] etch device country code from android phone

[Sirisha Ch]

fetch device country code from android phone is not returning right result
using Locale in Android. I have tried following methods but not working
when there is no sim card in device. Even for Indian device it is showing US
1) public static String getUserCountry(Context context) {
try {
final TelephonyManager tm = (TelephonyManager)
context.getSystemService(Context.TELEPHONY_SERVICE);
final String simCountry = tm.getSimCountryIso();
if (simCountry != null && simCountry.length() == 2) { // SIM country code
is available
return simCountry.toLowerCase(Locale.US);
}
else if (tm.getPhoneType() != TelephonyManager.PHONE_TYPE_CDMA) { // device
is not 3G (would be unreliable)
String networkCountry = tm.getNetworkCountryIso();
if (networkCountry != null && networkCountry.length() == 2) { // network
country code is available
return networkCountry.toLowerCase(Locale.US);
}
}
}
catch (Exception e) { }
return null;
}
2) TelephonyManager tm =
(TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);
String countryCode = tm.getSimCountryIso();

3) String locale =
context.getResources().getConfiguration().locale.getCountry(Locale.getDefault());
System.out.println("country = "+locale);
