title: Android URL for facebook sharing
body: <p>I noticed there are many urls like: tel:0982222222 (in Android, would create an intent which would route to a make-call utility) sms:0982222222 (the same but prepares an SMS. also accepts a body with the message to prepare the application).</p>
  
  <p>I want to share an url in facebook, from another app. The fact is that the app is made in PhoneGap so I can't use any native solutions (like manually creating an intent) since the button (a custom button intended to Share the current url) is displayed in the standard phonegap WebView, so i'd need a link-button like:</p>
  
  <pre><code>&lt;a href="xxx:yyy" class="my-custom-button-class"&gt;Share&lt;/a&gt;
  </code></pre>
  
  <p>xxx:yyy would be like tel:0982222222 if i wanted to link to a phonecall app.</p>
  
  <p><strong>Q</strong>: How would I compose such url if I wanted to share the url <a href="http://bar.foo.com/path/point?param1=a&amp;param2=2&amp;param3=%5b%5d" rel="nofollow">http://bar.foo.com/path/point?param1=a&amp;param2=2&amp;param3=[]</a> (or the exact same case for https)?</p>
