ActionBar doesn't load the home drawable correctly
<p>I think I've found a bug in the Action Bar Compatibility (ActionBarCompat).
I've reported it and I've been asked to post it here.</p>

<p>When I define a XML selector drawable for the home icon saving it as ic_home.xml in the drawable folder, it doesn't load the icon if the device is hdpi.</p>

<p>The correct behaviour should be to load the icons from the hdpi-v4 folder even though the xml is only in the drawable folder and not the drawable-hdpi-v4.</p>

<p>By placing the ic_home.xml also in the drawable-hdpi-v4 folder solves the problem and the home icon is displayed correctly.</p>

<p>I've managed to reproduce this behaviour in the Android 1.6 emulator and in a ZTE Blade running Android 2.3.7.</p>

<p>Here is the directory structure that I used:</p>

<pre><code>drawable/action_home_focus.png
drawable/action_home_normal.png
drawable/action_home_pressed.png
drawable/ic_home.xml
drawable-hdpi-v4/action_home_focus.png
drawable-hdpi-v4/action_home_normal.png
drawable-hdpi-v4/action_home_pressed.png
</code></pre>

<p>And here is my XML selector drawable (ic_home.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;item android:drawable="@drawable/action_home_focus" 
        android:state_focused="true"/&gt;
  &lt;item android:drawable="@drawable/action_home_pressed" 
        android:state_pressed="true"/&gt;
  &lt;item android:drawable="@drawable/action_home_normal"/&gt;
&lt;/selector&gt;
</code></pre>

<p>By using that directory structure, the home icon doesn't get loaded in an hdpi device. The only way to get it to load is to copy the ic_home.xml also to the drawable-hdpi-v4 folder.</p>

<p>I was expecting that, besides ic_home.xml being only in the drawable folder, it would load the icons from drawable-hdpi-v4 if the device is hdpi.</p>
