Please use this function to pass phone number and country code like india 91

contacts

public static String parseContact(String contact, String countrycode) {
    PhoneNumber phoneNumber = null;
    PhoneNumberUtil phoneNumberUtil = PhoneNumberUtil.getInstance();
    String finalNumber = null;
    String isoCode = phoneNumberUtil.getRegionCodeForCountryCode(Integer.parseInt(countrycode));
    boolean isValid = false;
    PhoneNumberType isMobile = null;
    try {
        phoneNumber = phoneNumberUtil.parse(contact, isoCode);
        isValid = phoneNumberUtil.isValidNumber(phoneNumber);
        isMobile = phoneNumberUtil.getNumberType(phoneNumber);

    } catch (NumberParseException e) {
        e.printStackTrace();
    } catch (NullPointerException e) {
        e.printStackTrace();
    }


    if (isValid
            && (PhoneNumberType.MOBILE == isMobile || PhoneNumberType.FIXED_LINE_OR_MOBILE == isMobile)) {
        finalNumber = phoneNumberUtil.format(phoneNumber,
                PhoneNumberFormat.E164).substring(1);
    }

    return finalNumber;
}





PhoneNumberUtil phoneUtil = PhoneNumberUtil.getInstance();
try {
    // phone must begin with '+'
    PhoneNumber numberProto = phoneUtil.parse(phone, "");
    int countryCode = numberProto.getCountryCode();
} catch (NumberParseException e) {
    System.err.println("NumberParseException was thrown: " + e.toString());
}
