Question

我正在尝试从我的活动的onResume（）调用一个类。但是evrytime我得到的课程没有找到错误。

以下是onResume（）的代码：

 @Override
    protected void onResume() {
        super.onResume();
      try {   
          sendHiddenMail sender = new sendHiddenMail("sidh*****@gmail.com", "pass");
          sender.sendMail("This is Subject",   
                  "This is Body",   
                  "sid*****@gmail.com",   
                  "sid*****@gmail.com");   
      } catch (Exception e) {   
          Log.e("SendMailsdfsdfsd", e.getMessage(), e);   
      }

 }

以下是我想打电话的课程：

public class sendHiddenMail extends javax.mail.Authenticator{

private String mailhost = "smtp.gmail.com";   
private String user;   
private String password;   
private Session session;   

static {   
    Security.addProvider(new com.provider.JSSEProvider());   
}  


 public sendHiddenMail(String user, String password) {   
        this.user = user;   
        this.password = password;   

        Properties props = new Properties();   
        props.setProperty("mail.transport.protocol", "smtp");   
        props.setProperty("mail.host", mailhost);   
        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");   

        session = Session.getDefaultInstance(props, this);   
    }   

    protected PasswordAuthentication getPasswordAuthentication() {   
        return new PasswordAuthentication(user, password);   
    }   

    public synchronized void sendMail(String subject, String body, String sender, String recipients) throws Exception {   
        try{
        MimeMessage message = new MimeMessage(session);   
        DataHandler handler = new DataHandler(new ByteArrayDataSource(body.getBytes(), "text/plain"));   
        message.setSender(new InternetAddress(sender));   
        message.setSubject(subject);   
        message.setDataHandler(handler);   
        if (recipients.indexOf(',') > 0)   
            message.setRecipients(Message.RecipientType.TO, InternetAddress.parse(recipients));   
        else  
            message.setRecipient(Message.RecipientType.TO, new InternetAddress(recipients));   
        Transport.send(message);   
        }catch(Exception e){

        }
    }   

    public class ByteArrayDataSource implements DataSource {   
        private byte[] data;   
        private String type;   

        public ByteArrayDataSource(byte[] data, String type) {   
            super();   
            this.data = data;   
            this.type = type;   
        }   

        public ByteArrayDataSource(byte[] data) {   
            super();   
            this.data = data;   
        }   

        public void setType(String type) {   
            this.type = type;   
        }   

        public String getContentType() {   
            if (type == null)   
                return "application/octet-stream";   
            else  
                return type;   
        }   

        public InputStream getInputStream() throws IOException {   
            return new ByteArrayInputStream(data);   
        }   

        public String getName() {   
            return "ByteArrayDataSource";   
        }   

        public OutputStream getOutputStream() throws IOException {   
            throw new IOException("Not Supported");   
        }   
    }   

}

这是logcat：

我没有在mainfest.xml中添加任何有关sendHiddenMail类的信息

我不知道我哪里出错了。

Answer 1

正确导入javax.mail.Authenticator后，在“编译”时没有错误，应用程序在运行时崩溃，解决方案可能是this link。是的，如果您删除了类关系，您的代码可能会起作用，但它无法解决您的问题。尝试清理和重建项目。

android：从onResume（）
