title: Android app settings: why bother using PreferenceFragment if it's not supported before API 11?
body: <p>PreferenceFragment is supported for implementing application preferences beginning with API 11 (<a href="http://developer.android.com/guide/topics/ui/settings.html#Fragment" rel="nofollow">http://developer.android.com/guide/topics/ui/settings.html#Fragment</a>). Prior to API 11, PreferenceActivity was used.</p>
  
  <p>I have seen people struggle to implement PreferenceActivity for devices running older APIs while using PreferenceFragment for devices using newer APIs, in the same application.</p>
  
  <p>Can anybody help me understand why we would bother to implement PreferenceFragment. Why not just continue to use PreferenceActivity? That is what I am doing in my application as of now.</p>
