Hello Views/Form Stuff/Custon Button tutorial error
<p>Flush with success on getting "hello Android" to run, I'm working on the tutorial at <a href="http://developer.android.com/resources/tutorials/views/hello-formstuff.html#CustomButton" rel="nofollow">link text</a> using Eclipse. When I create the android_button.xml file in res/drawable/, I get errors for each of the  in </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;item android:drawable="@drawable/android_pressed"
          android:state_pressed="true" /&gt;
    &lt;item android:drawable="@drawable/android_focused"
          android:state_focused="true" /&gt;
    &lt;item android:drawable="@drawable/android_normal" /&gt;
&lt;/selector&gt;
</code></pre>

<p>The errors (repeated for each item) are:</p>

<pre><code>Description Resource    Location    Type    Path
error: Error: No resource found that matches the given name (at 'drawable' with value '@drawable/android_focused'). android_button.xml  line 5  Android AAPT Problem    /HelloFormStuff/res/drawable
error: Error: No resource found that matches the given name (at 'drawable' with value '@drawable/android_focused'). android_button.xml  line 5  Android AAPT Problem    /HelloFormStuff/res/drawable
</code></pre>

<p>I'm afraid I don't know which resource should match the names or if I have overlooked something or misnamed something. Help resolving this is greatly appreciated!</p>
