Android layout folder configuration
<p>I currently have 2 layout folders: layout-sw480dp and layout-sw720dp, both containing main.xml</p>

<p>I see that dev guide states the following:</p>

<pre><code> - 320dp: a typical phone screen (240x320 ldpi, 320x480 mdpi, 480x800
   hdpi, etc).
 - 480dp: a tweener tablet like the Streak (480x800 mdpi).
 - 600dp: a 7” tablet (600x1024 mdpi).
 - 720dp: a 10” tablet (720x1280 mdpi, 800x1280 mdpi, etc).
</code></pre>

<p>I'm developing using my Nexus 7 (emulator is a bit sucky/slow), when I upload my app to my tablet, I can tell it uses layout-sw480dp, but why? Ok it's not a 10" tablet but the Nexus 7 does have 800x1280 res, which I guess is irrelevant? I'm just a little confused as to which swdp to have.</p>

<p>According to GSMArena: <a href="http://www.gsmarena.com/asus_google_nexus_7-4850.php" rel="nofollow">http://www.gsmarena.com/asus_google_nexus_7-4850.php</a></p>

<pre><code> - 800 x 1280 pixels, 7.0 inches (~216 ppi pixel density)
</code></pre>
