title: Can I extend Androids Contacts database?
body: <p>I was wondering is it possible to extend the Android Contacts database?</p>
  
  <p>From here - <a href="http://d.android.com/reference/android/provider/ContactsContract.html">http://d.android.com/reference/android/provider/ContactsContract.html</a></p>
  
  <p>It says:</p>
  
  <blockquote>
    <p>ContactsContract defines an extensible
    database of contact-related
    information</p>
  </blockquote>
  
  <p>Extensible would suggest to me that I can add in more data to the contacts application outside the normal values such as Name, number, email, work number, home number etc..</p>
  
  <p>However the examples of this page - <a href="http://d.android.com/reference/android/provider/ContactsContract.RawContacts.html">http://d.android.com/reference/android/provider/ContactsContract.RawContacts.html</a> only show how to insert the standard values like name and not how to add a new field to a contact.</p>
  
  <p>Furthermore a search on the web does not turn up much information on extending the contacts data. </p>
  
  <p>So I was wondering is it even possible or does the extensible refer to some other part of the contacts?</p>
  
  <p>For example I would like to add in an additional field for contacts that have special privileges within my app so when a user looks at the contacts he or she knows what users they can use my app with.</p>
  
  <p>Is this possible?</p>
