title: How to know which intent is selected in Intent.ACTION_SEND?
body: <p>I want to use Android Intent.ACTION_SEND for quickly sharing something. So I got a sharing list like this:
  <img src="https://i.stack.imgur.com/j7itx.png" alt="Sharing intent list"></p>
  
  <p>But I want to share different content for each action, such as:</p>
  
  <ul>
  <li><p>If sharing by Email/Gmail, content should be "Share by email".</p></li>
  <li><p>If sharing by Facebook, content should be "Share by Facebook".</p></li>
  </ul>
  
  <p>So, is it possible to do that?</p>
