Answer 1:

 public class MailImageFile extends javax.mail.Authenticator {

            public MailImageFile(){}

     public void Mail(String user, String pass) {
        Properties props = new Properties();
        props.put("mail.smtp.host", "smtp.gmail.com");
        props.put("mail.smtp.socketFactory.port", "465");
        props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
        props.put("mail.smtp.auth", "true");
        props.put("mail.smtp.port", "465");

        Session session = Session.getDefaultInstance(props, new javax.mail.Authenticator()           {
            protected PasswordAuthentication getPasswordAuthentication() {
                return new PasswordAuthentication("[e-mail]", "pqr123%");
            }
            });
        try {
            Message message = new MimeMessage(session);
            message.setFrom(new InternetAddress("[e-mail]"));
            message.setRecipients(Message.RecipientType.TO,     InternetAddress.parse("[e-mail]"));
    message.setContent(_multipart);
            message.setSubject("Testing Subject");
            message.setContent("Hi...", "text/html; charset=utf-8");

            Transport.send(message);

        } catch (MessagingException e) {
            throw new RuntimeException(e);
        }

// 得到这个解决方案的形式在这里

    private Multipart _multipart; 
_multipart = new MimeMultipart(); 

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

    BodyPart messageBodyPart2 = new MimeBodyPart(); 
    messageBodyPart2.setText(subject); 

    _multipart.addBodyPart(messageBodyPart2); 
} 


    }

Answer 2:

试试这个代码：

Intent myEmailIntent = new Intent(android.content.Intent.ACTION_SEND);
        myEmailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT,"Email Subject");
        myEmailIntent.putExtra(android.content.Intent.EXTRA_EMAIL,new String[]{"[e-mail]"});

        myEmailIntent.putExtra(android.content.Intent.EXTRA_TEXT,"your email message");
        //message type
        myEmailIntent.setType("text/plain");
        File myAttachmentfile = getFileStreamPath("path of the file that you want to attach Eg: image");
        myEmailIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
        //attachment type
        myEmailIntent.setType("image/jpeg");
        myEmailIntent.putExtra(Intent.EXTRA_STREAM, Uri.parse("file://"+myAttachmentfile.getAbsolutePath()));
        startActivityForResult(Intent.createChooser(myEmailIntent, "SENDER NAME"),101);

//这是你如何连接的图像或任何文件以电子邮件

emailIntent.putExtra(Intent.EXTRA_STREAM, "your file path");

让我知道，如果它为你工作。

Answer 3:

Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND);

emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL, emailaddress);
emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, message);
emailIntent.setType("image/png");

ArrayList<Uri> uris = new ArrayList<Uri>();

uris.add(Uri.parse("android.resource://" + getPackageName() + "/" + R.drawable.file1));
uris.add(Uri.parse("android.resource://" + getPackageName() + "/" + R.drawable.file2));

emailIntent.putExtra(Intent.EXTRA_STREAM, uris));

startActivity(emailIntent);

这必将有助于您附上您的图像，而无需使用意图。

Multipart multipart = new MimeMultipart();

MimeBodyPart attachPart = new MimeBodyPart();
String attachFile = "/storage/emulated/0/pic.jpg";//picture location

DataSource source = new FileDataSource(attachFile);
attachPart.setDataHandler(new DataHandler(source));
attachPart.setFileName(new File(attachFile).getName());

//Trick is to add the content-id header here
attachPart.setHeader("Content-ID", "image_id");
multipart.addBodyPart(attachPart);

//third part for displaying image in the email body
attachPart = new MimeBodyPart();
attachPart.setContent("<h1>Attached Image</h1>" +
        "<img src='cid:image_id'>", "text/html");
multipart.addBodyPart(attachPart);
//Set the multipart message to the email message
message.setContent(multipart);

Transport.send(message);
System.out.println("Done");
