title: Firebase Notification Line break
body: <p>Can I know how to put a new line or line break in Firebase Notification body parameter?
  The notification from the phone shown as:</p>
  
  <pre> Title: Title 1 Author: Author 1 </pre>
  
  <p>What I expected was: </p>
  
  <pre>
  Title: Title 1 
  Author: Author 1
  </pre>
  
  <p>Any clue on this? Below is the code, I have tried with \n \n \n\r, but they are not working at all.</p>
  
  <pre><code>JSONObject body = new JSONObject();
      body.put("body", "Title: Title 1\n"
                          + "Author: Author 1");
  </code></pre>
