title: getChildFragmentManager() and support libraries
body: <p>I am using the <code>getChildFragmentManager()</code> in an app that is compiling against API level 19, with the minimum SDK set to 14. </p>
  
  <p><code>getChildFragmentManager()</code> was introduced in API 17, so devices running at API levels 14, 15, or 16 will throw a <code>NoSuchMethodError</code> when the method is called.</p>
  
  <p>I did look through all the other StackOverflow questions regarding this issue, but none of them seem to answer this question: is there any way to get the <code>getChildFragmentManager()</code> method to work on devices pre-API level 17? If so, how?</p>
  
  <p>The method does not seem to be included in either the v4 or v13 support libraries. I have tried clean builds with both v4 and v13 support libraries, but that does not seem to solve the issue.</p>
