title: How can I use ANY public class referenced online
body: <p>In Xamarin, how can I get the correct information to implement any class in an application.</p>
  
  <p>I will use this class reference as an example: <a href="http://developer.android.com/reference/com/google/android/gms/maps/SupportMapFragment.html" rel="nofollow">http://developer.android.com/reference/com/google/android/gms/maps/SupportMapFragment.html</a></p>
  
  <p>The class type is <code>SupportMapFragment</code>. How can I create an activity that extends <code>SupportMapFragment</code>?</p>
  
  <p>The only information that I can see on this page is the following:</p>
  
  <blockquote>
    <p>java.lang.Object
       ↳  android.support.v4.app.Fragment
         ↳    com.google.android.gms.maps.SupportMapFragment</p>
  </blockquote>
  
  <p>How use the SupportMapFragment class in a new activity?</p>
  
  <p>Can I please have a step by step list of instructions on how to do this? Not just for this <code>SupportMapFragment</code> class, but any class that I find on a web resource such as the link at the top of this post.</p>
  
  <p>Thanks in advance</p>
