Add Following Code.

In gradle

 compile 'com.googlecode.libphonenumber:libphonenumber:8.5.2'

In Activity class

PhoneNumberUtil phoneNumberUtil = PhoneNumberUtil.getInstance();
    String isoCode = phoneNumberUtil.getRegionCodeForCountryCode(Integer.parseInt(countryCode));
    String  exampleNumber= String.valueOf(phoneNumberUtil.getExampleNumber(isoCode).getNationalNumber());
    int phoneLength=exampleNumber.length();
    editTextLoginPhone.setFilters( new InputFilter[] {
            new InputFilter.LengthFilter(phoneLength)});

Hope this code will help you.

You can try this code for Indian Phone numbers:-

private static boolean isValidPhoneNumber(String mobile) {
    String regEx = "^[0-9]{10}$";
    return mobile.matches(regEx);
}

if you not want to use the internet of checking the number valid or not , you can do programmatically though its long but solution can be this only . Go to link : https://en.wikipedia.org/wiki/List_of_mobile_phone_number_series_by_country

and do programmatically the validation with conditions.
