title: How to add a menu to MapActivity?
body: <p>I've got an app using MapActivity.onCreate() to initialize the map and show it on screen. Now I would like to add a menu to my app. From what I've found out I can't add a menu from MapActivity and need to use Activity (correct me if I'm wrong).</p>
  
  <p>Now I have no idea how to "initialize" the map from my Activity-class.</p>
  
  <p>And how would I have to fix the views, will I wrap my activity-layout around my Map-layout?</p>
