android后台不借助Intent发送Email

核心提示:MimeMessage msg = new MimeMessage(session); msg.setFrom(new InternetAddress(_from)); InternetAddress[] addressTo = new InternetAddress[_to.length]; for (int i =

MimeMessage msg = new MimeMessage(session);

msg.setFrom(new InternetAddress(_from));

InternetAddress[] addressTo = new InternetAddress[_to.length];
for (int i = 0; i < _to.length; i++) {
addressTo[i] = new InternetAddress(_to[i]);
}
msg.setRecipients(MimeMessage.RecipientType.TO, addressTo);

msg.setSubject(_subject);
msg.setSentDate(new Date());

// setup message body
BodyPart messageBodyPart = new MimeBodyPart();
messageBodyPart.setText(_body);
_multipart.addBodyPart(messageBodyPart);

// Put parts in message
msg.setContent(_multipart);

// send email
Transport.send(msg);

return true;
} else {
return false;
}
}

public void addAttachment(String filename) throws Exception {
BodyPart messageBodyPart = new MimeBodyPart();
DataSource source = new FileDataSource(filename);
messageBodyPart.setDataHandler(new DataHandler(source));
messageBodyPart.setFileName(filename);

_multipart.addBodyPart(messageBodyPart);
}

@Override
public PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(_user, _pass);
}

private Properties _setProperties() {
Properties props = new Properties();

props.put("mail.smtp.host", _host);

if(_debuggable) {
props.put("mail.debug", "true");
}

if(_auth) {
props.put("mail.smtp.auth", "true");
}

props.put("mail.smtp.port", _port);
props.put("mail.smtp.socketFactory.port", _sport);
props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
props.put("mail.smtp.socketFactory.fallback", "false");

return props;
}

// the getters and setters
public String getBody() {
return _body;
}

public void setBody(String _body) {
this._body = _body;
}

// more of the getters and setters …..
}

And now I'm going to go through each bit of code

public Mail() {
_host = "smtp.gmail.com"; // default smtp server
_port = "465"; // default smtp port
_sport = "465"; // default socketfactory port

_user = ""; // username
_pass = ""; // password
_from = ""; // email sent from
_subject = ""; // email subject
_body = ""; // email body

_debuggable = false; // debug mode on or off - default off
_auth = true; // smtp authentication - default on

_multipart = new MimeMultipart();

// There is something wrong with MailCap, javamail can not find a handler for the multipart/mixed part, so this bit needs to be added.
MailcapCommandMap mc = (MailcapCommandMap) CommandMap.getDefaultCommandMap();
