title: Error inflating class fragment class not found android.view.fragment but I am including the compatability library?
body: <p>I am seeing a class not found exception for android.view.fragment although I am using the compatibility library.  Compiles fine but crashes.  Is there another package that I should use when pre 3.0?  I already changed all fragment classes to android.support.v4.app.Frament but it still crashes because of what is in the layout. My SDK is 4.03 but device is 2.3.</p>
  
  <p>Here is layout</p>
  
  <pre><code>    &lt;?xml version="1.0" encoding="utf-8"?&gt;
   &lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="fill_parent"
  android:layout_height="fill_parent"
  android:orientation="horizontal" &gt;
  &lt;fragment
      android:id="@+id/frag_series"
      android:layout_width="200dip"
      android:layout_height="match_parent"
      android:layout_marginTop="?android:attr/actionBarSize"
      class="com.authorwjf.hello_fragments.ListFrag" /&gt;
  &lt;fragment
      android:id="@+id/frag_capt"
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      class="com.authorwjf.hello_fragments.DetailFrag" /&gt;
  &lt;/LinearLayout&gt;
