title: Android - Empty PreferenceFragment after HoloEverywhere update
body: <p>after updating ADT i had lots of issues and deleted my Workspace and recloned everything with git and got a newer HoloEverywhere revision (dont know previous revision, but i want to use latest). </p>
  
  <p>I had to check my libs in BuildPath/Order and had to fix all compiler errors (like changing imports from org.holoeverywhere.arrayadapter to org.holoeverywhere.widget.arrayadapter), and now everything except my PreferenceFragments is working again.</p>
  
  <p>How i make the PreferenceFragments work again?</p>
  
  <p>When i start a activity, which attaches the PreferenceFragment via </p>
  
  <pre><code>getSupportFragmentManager().beginTransaction()
                  .replace(android.R.id.content, new SettingsFragment()).commit();
  </code></pre>
  
  <p>i get a blank Activity.</p>
  
  <p>The PreferenceFragment is also pretty simple: only </p>
  
  <pre><code>addPreferencesFromResource(R.xml.settings);
  </code></pre>
  
  <p>in onCreate (i have also one with dynamic Preferences, dont work also -> not a xml problem)</p>
  
  <p>anything worked before i updated ADT/HoloEverywhere</p>
  
  <p>what can i do to make the PreferenceFragments work again? Logcat does not say anything special and i have also added the PreferenceFramework (as i did also before);</p>
