title: Perform some action with custom field of Contact
body: <p>I have added custom field for my Contacts. It consists of:</p>
  
  <pre><code>&lt;ContactsSource xmlns:android="http://schemas.android.com/apk/res/android"&gt;
   &lt;ContactsDataKind
    android:icon="@drawable/ic_launcher"
    android:mimeType="vnd.android.cursor.item/vnd.com.mob.my_new.profile"
    android:summaryColumn="data2"
    android:detailColumn="data3"
    android:detailSocialSummary="true" /&gt;
  </code></pre>
  
  <p></p>
  
  <p>for now. I want to perform some action (for example - launch an activity) when user selects this my field in Android Contacs. How I can implement this?
  (It will be similar to facebook custom field - showing profile page)</p>
