title: android Convert phone number in International Format
body: <p>I'd like to know whether it's possible to have phone numbers converted
  into international format when a call is outgoing.</p>
  
  <p>For instance, if a french user (sorry it's the only format i know i
  won't make a mistake :-) try to call with the national format :
  01.47.12.34.56 then a method will convert it into international format
  like this : +33.1.47.12.34.56</p>
  
  <p>I've looked into the doc of the PhoneNumberUtils but i don't know if
  there is a method doing what i want. </p>
