Android setBackgroundResource doesn't use image depend on dpi
<p>I wan't to use the setBackgroundResource method to set an image to a button. </p>

<p>I have different folders with the same button in different dpi's but when I set the button from code it uses the drawable folder instead of the correct folder</p>

<pre><code>resume.setBackgroundResource(R.drawable.resumegrey);
</code></pre>

<p><img src="http://i.stack.imgur.com/xdjkh.jpg" alt="folders"></p>

<p>the resumegrey is copied in the right folders with diffrent dpi's</p>
