title: Should I use AppCompat v7 if minsdk is 14
body: <p>should I still use app compat v7 if my app has minSdk = 14?</p>
  
  <p>Is there any advantage with ActionBar in Android L ?</p>
  
  <p>Should I use android.support.v4.app.FragmentActivity from support v4 or should I use the android.app.Activity class (which has support for fragments since honeycomb)? </p>
  
  <p>Should I also use android.app.Fragment or android.support.v4.app.Fragment?</p>
  
  <p>I guess that I should use support v4 FragmentActivity and Fragment, but there is no need for app compat v7, right?</p>
  
  <p>What do you think?</p>
