title: Tablet-friendly interface and compatibility in Android development
body: <p>I want to develop a new Android app. Design guidelines for Droid 3.0+ encourage the use of fragments to create a UI that better utilizes tablets' screen space. Also, from Droid 3.0+ I have read that a menu bar should exist on every activity that has a menu instead of using the plain old menu key</p>
  
  <p><img src="https://i.stack.imgur.com/vTM3K.png" alt="Android UI menu bar"></p>
  
  <p>These features are supported by SDK 11+, but I want to support SDK 8 as minimum SDK in order to achieve best market share (see <a href="https://developer.android.com/about/dashboards/index.html" rel="nofollow noreferrer">here</a>).</p>
  
  <p>How can I achieve both of my objectives?</p>
