Using the Android support library to support older
<p>I'm developing an Android app and have been looking around a bit on how to support older versions(I've been developing for 4.0 while 10% of the phones are on 2.2 and 50% on 2.3). I've <a href="http://developer.android.com/tools/extras/support-library.html" rel="nofollow">found the support library</a> and wanted to see if I understood things correctly.</p>

<ol>
<li>I get the support library for version 2.2.</li>
<li>I switch from using the stuff from the normal .jar to the one from
the support library. Seems to be a bit of code changes and new imports.</li>
<li>My app is now working on Android 2.2</li>
</ol>
