title: formatted string phone number android
body: <p>I am currently exporting some of the phone numbers of contacts stored in the Contacts content provider, and I would like to know if something exists to get the 'formated' string for the phone number e.g. instead of xxx-xxx-xxxx => xxxxxxxxxx. for a better DB consistency.</p>
  
  <p>It would be pretty easy with a reg-ex, but i'd like to know if something already exists for this purpose, as the doc. mentions : </p>
  
  <pre><code>public static final String NUMBER - Since: API Level 5
  The phone number as the user **entered it**.
  Type: TEXT - Constant Value: "number"
  </code></pre>
  
  <p>which let's me think a standard format exists somewhere ... ?
  Thanks in advance !</p>
