title: GoogleMap- Black screen when transiting
body: <p>I am using <code>GoogleMap</code> along with <code>SherlockMapFragment</code>. After opening up the Google Map (full screen), I clicked on the phone's hardware Back menu. I realized there is a noticeable (1-2 secs) black screen as it transit to the previous fragment.</p>
  
  <p>Though the screen is black, the zoom levels (i.e + and - signs) can still be seen.</p>
  
  <p>Could you please explain how should I go about to prevent such black screens?</p>
  
  <p>Thanks! :)</p>
