NotFoundException when looking for Drawable resource
<p>I am starting with android and I want to add a border to cells as described <a href="http://stackoverflow.com/questions/2108456/how-to-create-a-table-with-borders-in-android">in this answer</a>. So I created my cell_background.xml file, which Eclipse created in <code>res\drawable</code> and that contains</p>

<pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
&lt;shape
   xmlns:android="http://schemas.android.com/apk/res/android"
   android:shape= "rectangle"  &gt;
    &lt;solid android:color="#000"/&gt;
    &lt;stroke android:width="1dp"  android:color="#ff9"/&gt;
&lt;/shape&gt;
</code></pre>

<p>Having read that there are several issues with the drawable folder, I copied it verbatim into the <code>res\drawable-*dpi</code> directories</p>

<p>Now, my app crashes in the following line</p>

<pre><code>Drawable drawable = Resources.getSystem().getDrawable(R.drawable.cell_background);
</code></pre>

<p>with this exception</p>

<pre><code>12-16 14:26:28.624: E/AndroidRuntime(533): Caused by: android.content.res.Resources$NotFoundException: Resource ID #0x7f020000
</code></pre>

<p>Both the project and the emulator are set to v3.0</p>

<p>Any ideas? I have already cleaned and rebuilt the project but it still crashes.</p>
