title: Can't invoke getChildFragmentManager in Fragment
body: <p>I am building android project with maven. But I found when I call <code>getChildFragmentManager</code> in <code>v4.Fragment</code>, it shows an error that this method is not found. I doubt that the <code>support-v4</code> package is not newer enough because if I using ant to build my project everything works just fine.</p>
  
  <p>However I can't get the newer <code>support-v4</code> to be included into my project.
  Here is my pom.xml</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
