问题
I am trying to implement an HTML format mail using the Java mail in android. I would like to get results like this:
When I look at the html format sent from lookout in my GMAIL. I don't see any link, but just has this format:
[image: Lookout_logo]
[image: Signal_flare_icon] Your battery level is really low, so we located
your device with Signal Flare.
I was trying the following:
Properties props = System.getProperties();
props.put("mail.smtp.starttls.enable", "true"); // added this line
props.put("mail.smtp.host", host);
props.put("mail.smtp.user", from);
props.put("mail.smtp.password", pass);
props.put("mail.smtp.port", "587");
props.put("mail.smtp.auth", "true");
javax.mail.Session session = javax.mail.Session.getDefaultInstance(props, null);
MimeMessage message = new MimeMessage(session);
message.setFrom(new InternetAddress(from));
InternetAddress[] toAddress = new InternetAddress[to.length];
// To get the array of addresses
for( int i=0; i < to.length; i++ )
{
// changed from a while loop
toAddress[i] = new InternetAddress(to[i]);
}
message.setRecipients(Message.RecipientType.BCC, toAddress);
message.setSubject(sub);
//message.setText(body);
body = "<!DOCTYPE html><html><body><img src=\"http://en.wikipedia.org/wiki/Krka_National_Park#mediaviewer/File:Krk_waterfalls.jpg\">";
message.setContent(body, "text/html; charset=utf-8");
Transport transport = session.getTransport("smtp");
transport.connect(host, from, pass);
transport.sendMessage(message, message.getAllRecipients());
transport.close();
When I look at the html format sent with the above code. I get the following:
<!DOCTYPE html><html><body><img src="http://en.wikipedia.org/wiki/Krka_National_Park#mediaviewer/File:Krk_waterfalls.jpg>
How to make sure the user will not be able to see any html code or URL link like the mail sent by LOOKOUT?
Thanks!
回答1:
Setting messageBody as text/html works perfectly in most of the context. Little confusing why it's not working with your case.
Hereby I'm attaching the way to get you move with sending html content with your email inside android. There are two side which are most commonly used in android for emailing contents, out of them you are already using one of them. I'm showing you the way with other one.

You can simplify the setContent call to message.setText(body, "html", "utf-8"); Other than that, I don't understand what your problem is. It sounds like you're seeing exactly the html that you're sending. If you want to see something different, send something different. Or is the problem that the html is not being displayed properly in your mail reader? If you want to copy the example message display at the top, you need to look at the actual html code in the message. Use the "Show as original" option in Gmail.
回答3:
Why you can't go for HtmlEmail?
import org.apache.commons.mail.DefaultAuthenticator;
import org.apache.commons.mail.EmailException;
import org.apache.commons.mail.HtmlEmail;
and
HtmlEmail htmlEmail = new HtmlEmail();
htmlEmail.setHostName("smtp.gmail.com");
htmlEmail.setSmtpPort(587);
htmlEmail.setDebug(true);
htmlEmail.setAuthenticator(new DefaultAuthenticator("userId", "password"));
htmlEmail.setTLS(true);
htmlEmail.addTo("recipient@gmail.com", "recipient");
htmlEmail.setFrom("sender@gmail.com", "sender");
htmlEmail.setSubject("Send HTML email with body content from URI");
htmlEmail.setHtmlMsg(responseBody);
htmlEmail.send();

You need to send a multi part email with 2 different content types:
- text/plain for the text view
- text/html for the HTML view
I've pasted an example below from "Why Multi-Part Email is Important" (posted by the folks at Litmus whose business is sending emails) which should help
X-sender: <sender@sendersdomain.com>
X-receiver: <somerecipient@recipientdomain.com>
From: "Senders Name" <sender@sendersdomain.com>
To: "Recipient Name" <somerecipient@recipientdomain.com>
Message-ID: <5bec11c119194c14999e592feb46e3cf@sendersdomain.com>
