在没有用户交互的情况下在android中发送电子邮件得到身份验证错误

Question

大家好，下面的代码我写的是在 android 中发送电子邮件，但我收到 auth 错误，请帮我解决这个问题

    private void sendMail(String email, String subject, String messageBody,File file) {
        Session session = createSessionObject();
//        new UpdateTask().execute();
        try {
            Message message = createMessage(email, subject, messageBody, session,file);

            new UpdateTask().execute(message);

        } catch (AddressException e) {
            e.printStackTrace();
        } catch (MessagingException e) {
            e.printStackTrace();
        } catch (UnsupportedEncodingException e) {
            e.printStackTrace();
        }
    }

    private Message createMessage(String email, String subject, String messageBody, Session session,File file) throws MessagingException, UnsupportedEncodingException {
        Message message = new MimeMessage(session);
        message.setFrom(new InternetAddress("XXXXXXXX@gmail.com", "Sound Check"));
        message.addRecipient(Message.RecipientType.TO, new InternetAddress(email, email));
        message.setSubject(subject);
        message.setText(messageBody);
        /**
         * Attach a file in mail 
         */
        Multipart multipart = new MimeMultipart();
        BodyPart messageBodyPart = new MimeBodyPart();
        DataSource source = new FileDataSource(file);
        messageBodyPart.setDataHandler(new DataHandler(source));
        messageBodyPart.setFileName(file.getName());

        multipart.addBodyPart(messageBodyPart);
        message.setContent(multipart);
        return message;
    }

    private Session createSessionObject() {
           Properties props = new Properties();   
           props.setProperty("mail.transport.protocol", "smtp");   
           props.setProperty("mail.host", "smtp.gmail.com");   
           props.put("mail.smtp.auth", "true");   
           props.put("mail.smtp.port", "465");   
           props.put("mail.smtp.socketFactory.port", "465");   
           props.put("mail.smtp.socketFactory.class",   
                   "javax.net.ssl.SSLSocketFactory");   
           props.put("mail.smtp.socketFactory.fallback", "false");   
           props.setProperty("mail.smtp.quitwait", "false");   

        return Session.getInstance(props, new javax.mail.Authenticator() {
            protected PasswordAuthentication getPasswordAuthentication() {
                return new PasswordAuthentication("xxxxxxxxxx@gmail.com", "*********");
            }
        });
    }
}
class UpdateTask extends AsyncTask<Message,String,String> {



    @Override
    protected String doInBackground(Message... params) {
        // TODO Auto-generated method stub
        Message message = params[0];
         try {

                Transport.send(message);

            } catch (AddressException e) {
                e.printStackTrace();
            } catch (MessagingException e) {
                e.printStackTrace();
            }

        return null;
    }

}

出现这样的错误：

同时收到如下邮件：

sub : 登录尝试被阻止

邮件：

你好名字 有些人只是尝试登录不符合现代安全标准的 Google 帐户“mailid”表单应用程序。

Answer 1

这些是JavaMail中AuthenticationFailedException最常见的事情

1. 首先，修复这些common mistakes.
2. 开启Session debugging查看协议跟踪是否给出 关于问题的更多线索。
3. 你可能需要enable access for less secure apps.这个错误可能来自谷歌安全...这可以通过启用不太安全的“打开”来解决

完成所有这些步骤后，您仍然面临问题吗？我是来帮你的！！
