What are prerequisites for importing Android compatibility library packages?
<p>I'm trying to import ACL Fragment packages into Fragment tutorial project for API 4 in Eclipse, but get red underline error indication (see image):</p>

<p>I've ran Eclipse update and have installed these packages in AVD (see image):</p>

<p>What am I missing?</p>
