title: How to make Android 4.0 apps backwards compatible?
body: <p>Android 4.0 (ICS) has lots of <a href="http://developer.android.com/design/patterns/pure-android.html" rel="noreferrer">new UI guidelines</a> which are great. The problem is that going forward, I'm not sure how to build an app for Android 4.0 and make sure that the app looks the same/similar on devices running Android 2.2 and 2.3.</p>
  
  <p>There is the <a href="http://developer.android.com/sdk/compatibility-library.html" rel="noreferrer">Android compatibility library</a>, and a <a href="http://developer.android.com/resources/samples/ActionBarCompat/index.html" rel="noreferrer">backwards compatible Action Bar</a>, but I was looking for a more concrete solution for porting post-ICS apps to pre-ICS phones.</p>
  
  <p>Am I on the right track? Anyone have any thoughts?</p>
