  &lt;action
      android:name="android.intent.action.PHONE_STATE" /&gt;
  &lt;/intent-filter&gt;
  </code></pre>
  
  <ol>
  <li><p>How to check if the phone number receive is on my contact list ?<br>
  Do you have a tip to know if this phone number exist on contact list with out loading contact list ?<br>
  I don't want more information, just if this phone number exist.</p></li>
  <li><p>If it's not possible, and I must load contact list, how to do it on <code>BroadcastReceiver</code> ?<br>
  When I try to do <code>getContentResolver</code>, it's not working because I'm on <code>BroadcastReceiver</code> and not inside <code>Activity</code>...</p></li>
