    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()   {

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("[email protected]", "pqr123%"); 
      } 
      }); 
     try { 
      Message message = new MimeMessage(session); 
      message.setFrom(new InternetAddress("[email protected]")); 
      message.setRecipients(Message.RecipientType.TO,  InternetAddress.parse("[email protected]")); 
    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); 
     } 

// Got this solution form here

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); 
} 


    }

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[]{"[email protected]"}); 

     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"); 

让我知道它是否适合你。

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");
