PhoneNumberValidator

To help implement phone number validation before performing any further operation. Convert phone number to phone number with country code and also remove country code from a phone number and automatically get the country of a user. This library helps make sure the number is valid for the selected country.

Adding to your project.

compile 'xyz.belvi.validator:phonenumbervalidator:1.0.0'

Samples

See sample application in project for a brief walk through on how to use the library.

Snippet.

PhoneNumberVerifier numberVerifier = new PhoneNumberVerifier();

Countries can be gotten by:

  • automatically getting the user country
numberVerifier.getUserCountry()

this returns the users country or null if nothing is found

  • get user country by mc (mobile country code).

This is unique for all country

numberVerifier.getCountryByMnc(621)

to get mcc in android:

TelephonyManager telephonyManager = (TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE);
String simOperator = telephonyManager.getSimOperator();
if (!simOperator.isEmpty()) {
int mcc = Integer.parseInt(String.valueOf(context.getResources().getConfiguration().mcc));
}
  • phone number

get the country by passing a phone number to the method. This returns a country that allows the phone number format. The phone number should have a country code else, this method would return the default country passed to it.

numberVerifier.getCountryByPhoneNumber(Countries.CANADA, "2348123456789")
  • by name

returns country by name. Pass a string name of the coutry to get the country

numberVerifier.getCountryByName("Nigeria")
  • by country code

this returns a list of country as some country shares same country code.

numberVerifier.getCountriesByCountryCode(234)
  • direct initialisation

calling the country by its value type;

Countries country = PhoneNumberVerifier.Countries.Nigeria;

#Using the PhoneModel Class To check if a number is valid for a country, use the phoneModel class.

PhoneModel model = country.isNumberValid("08012345678");

model.isNumberValid() tells if the number is valid or not. If it is valid, you can basically a better formatted version of the number from model.getPhoneNumber(). This is empty when model.isNumberValid() is false;

#Converting Numbers Numbers can be converted to plain number from countrycode number and converted to plain number from counrtycode number (i.e) from 080231**** to +23481231**** or from +23481231**** to 080231****

use country.toPlainNumber(phonenumber) and country.toCountryCodeNumber(phonenumber) to achieve this

#Handling Exception Watch out for the PhoneFormatException. It is thrown when phone contains invalid characters mainly.
