title: First launch of Activity with Google Maps is very slow
body: <p>I want to have SupportMapFragment in one of my Activity. I add this fragment directly to layout xml and this layout set as content view. But when Activity is launched for the first time, it takes too long (over 1 second). Next launches are ok and take few milliseconds.</p>
  
  <p>I tried:</p>
  
  <ul>
  <li>remove any initialization</li>
  <li>use MapFragment instead of SupportMapFragment</li>
  <li>add MapFragment programatically</li>
  </ul>
  
  <p>but nothing helped. Map is shown without any problem or suspicious log. </p>
  
  <p>Do you have any suggestion, what it causes and how to improve it? </p>
  
  <p><strong>edit:</strong>
  I have a ListView and when user clicks on Item, it launches DetailActivity with MapFragment. After click on item there is a noticeable delay before DetailActivity shows up. Only method onCreate, where I call setContentView, runs over 1 second. And while activity is in onCreate method, there is no visible content from this activity. This delay between click and showing content is not very user friendly.</p>
  
  <p>Thank you</p>
