what is android support library
<p>what is the purpose of Android Support Library?
Does this mean </p>

<pre><code>   http://developer.android.com/tools/extras/support-library.html
</code></pre>

<p>Currently my app has min sdk restriction of level 10
I am trying to use ViewPager, which is not available at higher api (level 16 I believe)</p>

<p>So what does this support library mean? Does it mean I can use ViewPager and user of the phone with api level less than 16 can still see ViewPager widget?</p>

<p>Please help</p>
