如何將SD卡中的文件附加到GMail-Email

Question

我正在嘗試使用Android中的GmailSender附加SD文件。

我有這個： 通過GMailSender發送帶有附件的電子郵件嗎？

我檢查了文件是否存在，但是郵件無法正確發送。 沒有附加文件的相同方法運行正常。

可能是什么問題？

謝謝。

File imageFile = new File("/sdcard/prueba.jpg");
if (imageFile.exists()){
    Toast.makeText(getApplicationContext(),"Existe",Toast.LENGTH_LONG).show();
}else{
Toast.makeText(getApplicationContext(),"NO Existe", Toast.LENGTH_LONG).show();
}
gmail.sendMail("Datos", c.getMailBody(),Constants.getAddress(), udb.getMail(), imageFile);

我的GmailSender類：

    public class GMailSender extends javax.mail.Authenticator{

    private final static String defaultUserName = "particle";
    private final static String defaultPassword = "particle123";

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

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

    public GMailSender() {   
        new GMailSender(defaultUserName, defaultPassword);
    }

    public GMailSender(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 synchronized void sendMail(String subject, String body, String sender, String recipients, File attachment) throws Exception { 
        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(attachment!=null){
            MimeBodyPart mbp1 = new MimeBodyPart();
            mbp1.setText(body);
            MimeBodyPart mbp2 = new MimeBodyPart();
            FileDataSource fds = new FileDataSource(attachment);
            mbp2.setDataHandler(new DataHandler(fds));
            mbp2.setFileName(fds.getName());
            Multipart mp = new MimeMultipart();
            mp.addBodyPart(mbp1);
            mp.addBodyPart(mbp2);
            message.setContent(mp);
        }
        if (recipients.indexOf(',') > 0)   
            message.setRecipients(Message.RecipientType.TO, InternetAddress.parse(recipients));   
        else  
            message.setRecipient(Message.RecipientType.TO, new InternetAddress(recipients));   
        Transport.send(message);
    }


    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");   
        }   
    }   
} 

我的異常是：

javax.mail.MessagingException: IOException while sending message;

嵌套的異常是：javax.activation.UnsupportedDataTypeException：MIME類型為multipart / mixed的無對象DCH； boundary =“ ---- = _ Part_1_1079440400.1348225974758”在com.sun.mail.smtp.SMTPTransport.sendMessage（SMTPTransport.java:1177）在javax.mail.Transport.send0（Transport.java:195）在javax.mail android.app上的teru.SimDetect.TFC.SimDetectActivity.onCreate（SimDetectActivity.java:56）上的teru.SimDetect.TFC.GMailSender.sendMail（GMailSender.java:105）上的.Transport.send（Transport.java:124）。 Instrumentation.callActivityOnCreate（Instrumentation.java:1072）在android.app.ActivityThread.performLaunchActivity（ActivityThread.java:1836）在android.app.ActivityThread.handleLaunchActivity（ActivityThread.java:1893）在android.app.ActivityThread.access $ 1500（ android.app.ActivityThread $ H.handleMessage（ActivityThread.java:1054）上的ActivityThread.java:135）android.os.Looper.loop（Looper.java）上android.os.Handler.dispatchMessage（Handler.java:99）上的ActivityThread.java:135） ：150），位於android.app.ActivityThread.main（ActivityThread.java:4385），位於java.lang.reflect.Method.invokeNative（Native Method），位於java.lang.reflect.Method.invoke（Method.java:507） 在com.android.internal.os.ZygoteInit $ MethodAndArgsCaller.run（ZygoteInit.java:849）在com.android.internal.os.ZygoteInit.main（ZygoteInit.java:607）在dalvik.system.NativeStart.main（Native）方法）原因：javax.activation.UnsupportedDataTypeException：MIME類型為multipart / mixed的無對象DCH； boundary =“ ---- = _ Part_1_1079440400.1348225974758”在javax.mail.internet.MimeBodyPart上的javax.activation.ObjectDataContentHandler.writeTo（DataHandler.java:905）在javax.activation.DataHandler.writeTo（DataHandler.java:330） .writeTo（MimeBodyPart.java:1485）at javax.mail.internet.MimeMessage.writeTo（MimeMessage.java:1773）at com.sun.mail.smtp.SMTPTransport.sendMessage（SMTPTransport.java:1121）...另外17個

也許這可以幫助您：

String image = "prueba.jpg";
File file = new File(Environment.getExternalStorageDirectory(), image);
GMailSender sender = new GMailSender("user@gmail.com", "password");
sender.sendMail (head , body ,"user@gmail.com", "sendto@mail.com", file);

GmailSender已修改：

public synchronized void sendMail(String subject, String body, String sender, String recipients, File attachment) throws Exception { 
    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(attachment!=null){
        MimeBodyPart mbp1 = new MimeBodyPart();
        mbp1.setText(body);
        MimeBodyPart mbp2 = new MimeBodyPart();
        FileDataSource fds = new FileDataSource(attachment);
        mbp2.setDataHandler(new DataHandler(fds));
        mbp2.setFileName(fds.getName());
        Multipart mp = new MimeMultipart();
        mp.addBodyPart(mbp1);
        mp.addBodyPart(mbp2);
        message.setContent(mp);
    }
    if (recipients.indexOf(',') > 0)   
        message.setRecipients(Message.RecipientType.TO, InternetAddress.parse(recipients));   
    else  
        message.setRecipient(Message.RecipientType.TO, new InternetAddress(recipients));   
    Transport.send(message);
}

代碼很好，問題出在GMailSender庫上，它已經過時了。

謝謝。
