How to download and use ShareCompat library
<p>I need to share some text from my app to google plus and I googled and found many links saying<br>
to use ShareCompat and i found this code sample </p>

<pre><code>     Intent shareIntent = ShareCompat.IntentBuilder.from(ShareActivity.this)
.setText("This site has lots of great information about Android!
  http://www.android.com")
.setType("text/plain")
.getIntent()
.setPackage("com.google.android.apps.plus");

 startActivity(shareIntent);
</code></pre>

<p>But i want to know from where to download this ShareCompat API. Any one please can provide a link for this. Any kind of help will be appreciated. 
Many thanks,
Mona</p>
