What's wrong with my 9-patch PNG for Button
<p>I created a 9-patch PNG but it won't work. In the Android SDK Tool everything looks ok. But when i add it to a Button then i only see a pink background. The text placement (padding from the patch) seems to be ok. What am i doing wrong?</p>

<pre><code>     &lt;Button 
    android:id="@+id/button_settings"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:focusable="true"
    android:text="Settings"
    android:textColor="#fff"
    android:background="@drawable/button_settings_idle"
/&gt;
</code></pre>
