title: Android share intent issue
body: <p>I am trying to use share intent, but i think, it does not work correctly. In list of applications for sharing, Facebook or Pinterest do not appear but Gmail or Cloud Print do. 
  I want all possible applications to appear there.</p>
  
  <p>Here is my code.
  Thanks for any advices.</p>
  
  <pre><code>final Intent shareIntent = new Intent(Intent.ACTION_SEND);   
      shareIntent.setType("text/plain");   
      shareIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, "App name");
      shareIntent.putExtra(android.content.Intent.EXTRA_TEXT, "");
      startActivity(Intent.createChooser(shareIntent, "Share via..."));
  </code></pre>
