title: Android design support library setup trouble
body: <p>I'm completely confused with implementation of the Android design support library.  I tried to do almost everything advised on Stack Overflow, but I am still having compile-time errors on each widget from the design support library (Error parsing XML: Unbound prefix).      </p>
  
  <p>I'm developing in Eclipse.  Here's what have I done:    </p>
  
  <ol>
  <li><p>Downloaded last Android Support Library (23.0.1), Android Support Repository (21), API 23.</p></li>
  <li><p>Imported <code>android-support-v7-appcompat</code> as a library,<br>
  Project Properties - Android - Add. </p></li>
  <li><p>Copied last downloaded <code>android-support-design.jar</code>,<br>
  <code>android-support-v4.jar</code>,  <code>android-support-v7.jar</code><br>
  into <code>libs</code> folder of the project and imported them as:
  Profect Properties - Java Build Path - Libraries Add Jars and checked them on Order and Export.   </p></li>
  <li><p>I set up <code>targetSdkVersion="23"</code> in manifest,
      <code>target=android-23</code> in project.properties.  </p></li>
  <li><p>Changed theme in <code>styles.xml</code> as:</p>
  
  <p>
      
  </p>
  
  <p>
  </p></li>
  </ol>
  
  <p>My layout looks like this: </p>
  
  <pre><code>&lt;android.support.design.widget.AppBarLayout xmlns:android="http://schemas.android.com/apk/res/android"
      xmlns:tools="http://schemas.android.com/tools"
      android:layout_width="match_parent"
      android:layout_height="192dp" &gt;
  
      &lt;android.support.design.widget.CollapsingToolbarLayout
          android:layout_width="match_parent"
          android:layout_height="match_parent"
          app:layout_scrollFlags="scroll|exitUntilCollapsed" &gt;
  
          &lt;android.support.v7.widget.Toolbar
              android:layout_width="match_parent"
              android:layout_height="?attr/actionBarSize"
              app:layout_collapseMode="pin" /&gt;
      &lt;/android.support.design.widget.CollapsingToolbarLayout&gt;
  
  &lt;/android.support.design.widget.AppBarLayout&gt;
  </code></pre>
  
  <p>Any suggestions?</p>
