title: How can I show a DialogFragment using compatibility package?
body: <p>I've tried to use DialogFragment on 3.0- devices, which not supports Fragment or DialogFragment by SDK level.  </p>
  
  <p>So, I decided to use Android compatibility library, which supports Fragment.<br>
  Then I created a DialogFragment class that extends <strong>android.support.v4.app.DialogFragment</strong>.  </p>
  
  <p>But.....When I tried to show my DialogFragment using DialogFragment.show(), I notified that show(FragmentManager, String) accepts first argument as <strong>android.app.FragmentManager</strong>, not <strong>android.support.v4.app.FragmentManager</strong>.</p>
  
  <p>I think android.app.FragmentManager cannot be used in Android 3.0- devices, because it is not included in SDK.</p>
  
  <p>Is there any way to show DialogFragment with Compatibility library? Am I have to use another way to show My DialogFragment with compatibility library?</p>
  
  <p>Any help will be much appreciated. :) </p>
