title: Activity.FragmentManager is obsolete
body: <p>I'm working on google maps using fragment. API version is 23.</p>
  
  <pre><code>mapFragment = FragmentManager.FindFragmentById&lt;MapFragment&gt;(Resource.Id.mapFragment);
  </code></pre>
  
  <p>The above code is highlighted that it's obsolete.</p>
  
  <p>AXML file</p>
  
  <pre><code>&lt;fragment 
          android:layout_width="match_parent"
          android:layout_height="200dp" 
          class="com.google.android.gms.maps.MapFragment"
          android:id="@+id/mapFragment"/&gt;
