title: Rotate the screen close the app (instead of showing landscape layout)
body: <p>I have created a folder layout-land where I have put a modified copy of my main.xml layout (modified to display the layout in landscape). So I have main.xml in res/layout and modified main.xml in res/layout-land.</p>
  
  <p>When I rotate the phone in landscape before running my app, the good activity is displayed (same for vertical), but if I rotate while running the app, the activity "disappear" and the home screen is displayed...</p>
  
  <p>This only on main.xml, not on preferences screen (when I rotate, the screen rotate).</p>
  
  <p>It's not a FC: <em>activity is still running in background</em> no, app is killed by me!</p>
