title: Linking to facebook share from android browser
body: <p>I'm trying to link to the Facebook android app from the browser but can't find the right scheme. I looked at the suggestion from this post <a href="https://stackoverflow.com/a/15597586/2170265">here</a> and I changed some stuff around. When I try it in the browser it always takes me to the Play Store for Facebook and not the actual app, even though I have it installed. Also, when I try running the samples from the above post, they take me right to the QR scanner.</p>
  
  <p>Here is my best attempt: </p>
  
  <pre><code>&lt;a href="intent://fb/#Intent;package=com.facebook.katana;end"&gt;test me&lt;/a&gt;
  </code></pre>
