Android Facebook
<p>For single sign-on where should I include this below code to work..</p>

<p>In FACBOOK.Clas or somewhere else.. or in my main Activity .. I downloaded the code from <a href="https://github.com/facebook/facebook-android-sdk" rel="nofollow">https://github.com/facebook/facebook-android-sdk</a></p>

<p>facebookClient = new Facebook(FB_APP_ID);</p>

<pre><code>    facebookClient.authorize(this, 
        new String[] {"publish_stream", "read_stream", "offline_access"}, this);
</code></pre>
