如何在Android中没有用户交互的情况下发送电子邮件？我在Mail类和“g mail Sender”类中使用了很多代码，我使用了库并在清单中添加了Internet权限。
但是我的所有代码都给了我同样的错误，即端口没有经过身份验证。 我使用的是端口代码：465,888,585。我已经检查了所有这些，但每次都会出现同样的错误。
请帮帮我。

在我的情况下，我使用了Java Mail API，您可以使用下面的代码。请添加必要的详细信息，如用户名，密码，电子邮件ID等
public class Mail extends javax.mail.Authenticator {
private String _user;
private String _pass;
private String[] _to ;
private String _from;
private String _port;
private String _sport;
private String _host;
private String _subject;
private String _body;
private boolean _auth;
private boolean _debuggable;
private Multipart _multipart;
public Mail() {
_host = "smtp.gmail.com"; // default smtp server
_port = "465"; // default smtp port
_sport = "465"; // default socketfactory port
_user = "username"; // username
_pass = "password"; // password
_from = "emailsentfrom@gmail.com"; // email sent from
_to = new String[] {"toemail@gmail.com"};
_subject = "subject"; // email subject
_body = "test"; // 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();
mc.addMailcap("text/html;; x-java-content-handler=com.sun.mail.handlers.text_html");
mc.addMailcap("text/xml;; x-java-content-handler=com.sun.mail.handlers.text_xml");
mc.addMailcap("text/plain;; x-java-content-handler=com.sun.mail.handlers.text_plain");
mc.addMailcap("multipart/*;; x-java-content-handler=com.sun.mail.handlers.multipart_mixed");
mc.addMailcap("message/rfc822;; x-java-content-handler=com.sun.mail.handlers.message_rfc822");
CommandMap.setDefaultCommandMap(mc);
}
public Mail(String user, String pass) {
_user = user;
_pass = pass;
}
public boolean send() throws Exception {
Properties props = _setProperties();
if(!_user.equals("") && !_pass.equals("") && _to.length > 0 && !_from.equals("") && !_subject.equals("") && !_body.equals("")) {
Session session = Session.getInstance(props, this);
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);
// adding attachment
addAttachment("filename");//replace with file name u need
// Put parts in message
msg.setContent(_multipart);
// send email
Transport transport = session.getTransport("smtps");
transport.connect(_host, 465,_user, _pass);
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");
props.put("mail.smtp.starttls.enable", "true");
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 É..
}
并编写Async任务以发送邮件
public class SendTask extends AsyncTask<String, Integer, Integer> {
private ProgressDialog dialog;
private Context mContext;
public SendTask(Context mContext){
this.mContext = mContext;
}
protected void onPreExecute() {
this.dialog = new ProgressDialog(mContext);
this.dialog.setCancelable(false);
this.dialog.setMessage("sending");
this.dialog.show();
}
protected Integer doInBackground(String... ids) {
Mail mail = new Mail();
try {
mail.send();
} catch (Exception e) {
e.printStackTrace();
}
return 1;
}
}
