title: no resource found that matches the given name drawable tab_unselected
body: <p>I've been doing the Google Tutorial for Android</p>
  
  <pre><code>http://developer.android.com/training/index.html
  </code></pre>
  
  <p>and I'm on this section:</p>
  
  <pre><code>http://developer.android.com/training/basics/actionbar/styling.html
  </code></pre>
  
  <p>I created a file in drawable folder, named <code>actionbar_tab_indicator.xml</code> like on the tutorial and I get the error <code>no resource found that matches the given name (at @drawable with the value @drawable/tab_unselected</code> (I also have this error for all @drawable items in that file)</p>
  
  <p>the code for actionbar_tab_indicator.xml:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;selector xmlns:android="http://schemas.android.com/apk/res/android"&gt;
  
  &lt;!-- STATES WHEN BUTTON IS NOT PRESSED --&gt;
  
      &lt;!-- Non focused states --&gt;
      &lt;item android:state_focused="false" android:state_selected="false"
            android:state_pressed="false"
            android:drawable="@drawable/tab_unselected" /&gt;
      &lt;item android:state_focused="false" android:state_selected="true"
            android:state_pressed="false"
            android:drawable="@drawable/tab_selected" /&gt;
  
      &lt;!-- Focused states (such as when focused with a d-pad or mouse hover) --&gt;
      &lt;item android:state_focused="true" android:state_selected="false"
            android:state_pressed="false"
            android:drawable="@drawable/tab_unselected_focused" /&gt;
      &lt;item android:state_focused="true" android:state_selected="true"
            android:state_pressed="false"
            android:drawable="@drawable/tab_selected_focused" /&gt;
  
  
  &lt;!-- STATES WHEN BUTTON IS PRESSED --&gt;
  
      &lt;!-- Non focused states --&gt;
      &lt;item android:state_focused="false" android:state_selected="false"
            android:state_pressed="true"
            android:drawable="@drawable/tab_unselected_pressed" /&gt;
      &lt;item android:state_focused="false" android:state_selected="true"
          android:state_pressed="true"
          android:drawable="@drawable/tab_selected_pressed" /&gt;
  
      &lt;!-- Focused states (such as when focused with a d-pad or mouse hover) --&gt;
      &lt;item android:state_focused="true" android:state_selected="false"
            android:state_pressed="true"
            android:drawable="@drawable/tab_unselected_pressed" /&gt;
      &lt;item android:state_focused="true" android:state_selected="true"
            android:state_pressed="true"
            android:drawable="@drawable/tab_selected_pressed" /&gt;
  &lt;/selector&gt;
  </code></pre>
  
  <p>So my question is, what kind of resource is tab_unselected and all the others, png? It's supposed Eclipse grab these files here </p>
  
  <p><code>&lt;selector xmlns:android="http://schemas.android.com/apk/res/android"&gt;</code></p>
  
  <p>and how do I solve this? </p>
  
  <p>thx</p>
