title: How can know what kind of email client supported?
body: <p>I know I can use the following code to invoke default email client of Android to send email.<br>
  In plain text supported email client I need to use <code>"\n"</code> to make a newline, but in html supported  email client I need to use <code>"&lt;br/&gt;"</code> to make a newline.<br>
  How can know what kind of email client supported? Thanks!</p>
  
  <pre><code>Intent emailIntent=new Intent(Intent.ACTION_SEND);         
  
  String subject = "Your sms sent by email";
  String body = "aa"+"&lt;br/&gt;"+"bb";
  
  String[] extra = new String[]{"aa@gmail.com"};
  emailIntent.putExtra(Intent.EXTRA_EMAIL, extra);
  
  emailIntent.putExtra(Intent.EXTRA_SUBJECT, subject);
  emailIntent.putExtra(Intent.EXTRA_TEXT, body);
  emailIntent.setType("message/rfc822");
  
  startActivity(emailIntent);
  </code></pre>
