title: Load Annotations from XML after MapView loads
body: <p>Is there a way to load the <code>MapView</code> first then fill it with the annotations?  </p>
  
  <p>Reason why I ask: When I click on my map which calls my XML first to fill the annotations, there is a <em>delay</em> and only then does the View open with my <code>MapView</code>.</p>
  
  <p>My concerns are that if the XML grows, it would delay even further or timeout.</p>
