making app crash

[AbdullahRaza]

hi,

When we select Saintbarthelemy, it has country code +590, which same as some other countries like Saint Martin. so This code decides the country code upon format of remaining number. if that number is invalid then this
String region = mPhoneUtil.getRegionCodeForNumber(phoneNumber);
returns null.
upon next line
int countryIdx = mCountries.indexOfIso(region);
in indexOfIso method .. toUpperCase is being called upon region which produces null pointer exception.

Pardon me if anything is wrong with creating this issue

Thanks
