How to get country code from Phone Book android

Question

I am working on android application where I want to detect the country code from my phone book where by default country code is not added. For example:

+971529090909,
00971529730000,
0529090909

In "+" and "00" state, I have country codes, but in case of "0" my country code is not available. I want to detect the country code of all contacts even if someone didn't put the country code.

How to detect country code/ Area code with any library or with any code snippet.

Answer 1

You can parse any number with any format using the libphonenumber library (maintained by Google), just specify the default Locale while parsing so it'll know what country code to default into.

You can play with an online version of it here.

TelephonyManager telephony = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
String simCountryIso = telephony.getSimCountryIso();
if (simCountryIso != null) 
    return simCountryIso.toUpperCase(loc);
} else {
    Locale loc = Locale.getDefault();
    return telephony.getNetworkCountryIso().toUpperCase(loc);
}
