Where can I find large Android 3.* example?
<p>I am very impressed with the stock Android 3.* Gmail app and I would like to find out how it's done.</p>

<p>The specifics of what I want to learn from the GMAIL app are:</p>

<ul>
<li>How the list fragment of the various inbox/folders are styled</li>
<li>How the interaction beween the inbox/folder and the email list</li>
<li>How the tapping on the email item will hide the inbox/folders and display the email content, and the animation involved</li>
<li>How the action bars, context menu and other menus get displayed, controller and event handled.</li>
</ul>

<p>Do you know any app -- which source is open for ppl to learn -- that come close to the Gmail app?</p>
