Contact picker filtering
<p>I use the contact picker in this way:</p>

<pre><code>    Intent intent = new Intent(Intent.ACTION_PICK, Contacts.CONTENT_URI);
    this.startActivityForResult(intent, PICK_CONTACT_REQUEST);
</code></pre>

<p>My question is if somehow the contact list can be filtered? For example I want to see only those contacts in the contact list which have at least a phone number or an email address.</p>
