Java 通过电子邮件发送从SurfaceView摄像头单击的文本消息和图像

我能够成功地从应用程序传递文本消息，但无法邮寄图像。我想传递邮件以及函数中计时器活动中的图像--

1.）主要活动

        transport.close();
        Log.i("GMail", "Email sent successfully.");

    }

}

好的，我会提供一些样品来跟进

在一个活动中，您启动了一个摄像头，目的是捕捉这样的图像

 Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
            startActivityForResult(cameraIntent, CAMERA_REQUEST); 

Intent i = new Intent(Intent.ACTION_SEND);
            i.putExtra(Intent.EXTRA_EMAIL, new String[]{"email@email.com"});
            i.putExtra(Intent.EXTRA_SUBJECT,"Its my attatchment");           
            i.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(pic)); //pic is the image you just captured 

            i.setType("image/png"); //format of image
            startActivity(Intent.createChooser(i,"Share image"));

在同一活动的onActivityResult中，您将设置缩略图并将其写入外部存储器

protected void onActivityResult(int requestCode, int resultCode, Intent data) {  
    if (requestCode == CAMERA_REQUEST) {  
     thumbnail = (Bitmap) data.getExtras().get("data");  
    ImageView image = (ImageView) findViewById(R.id.imageView);  
    image.setImageBitmap(thumbnail);


        try {
            File root = Environment.getExternalStorageDirectory();
            if (root.canWrite()){
                 pic = new File(root, "pic.png");
                FileOutputStream out = new FileOutputStream(pic);
                thumbnail.compress(CompressFormat.PNG, 100, out);
                out.flush();
                out.close();
            }
        } catch (IOException e) {
            Log.e("BROKEN", "Could not write file " + e.getMessage());
        }   

    }  

要在电子邮件中附加图像，您可以写以下内容

 Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
            startActivityForResult(cameraIntent, CAMERA_REQUEST); 

Intent i = new Intent(Intent.ACTION_SEND);
            i.putExtra(Intent.EXTRA_EMAIL, new String[]{"email@email.com"});
            i.putExtra(Intent.EXTRA_SUBJECT,"Its my attatchment");           
            i.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(pic)); //pic is the image you just captured 

            i.setType("image/png"); //format of image
            startActivity(Intent.createChooser(i,"Share image"));

希望这将帮助您完成任务。

尝试我使用的代码。

 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("abc@gmail.com", "pqr123%");
        }
        });
    try {
        Message message = new MimeMessage(session);
        message.setFrom(new InternetAddress("abc@gmail.com"));
        message.setRecipients(Message.RecipientType.TO,     InternetAddress.parse("xyz@gmail.com"));
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);
    }

附件代码

      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); }}

尝试图像数据url。它类似于普通文本，您可以将其放入

您的化身的数据url为：

数据：图像/png；base64，2.这个词的意思是：一个研究领域的一个研究领域的一个研究领域的一个研究领域的一个研究领域的一个研究领域的一个研究领域的一个研究领域的一个研究领域的一个研究领域的一个研究领域的一个研究领域的一个研究领域的一个研究领域的一个研究领域的一个研究领域的一个研究领域的一个研究领域的一个研究领域的一个研究领域的一个研究领域的一个研究领域的一个研究领域的一个研究领域的一个研究领域的一个研究领域的一个研究领域，一个研究领域的一个研究领域的一个研究领域的一个研究领域的一个研究领域的一个研究领域的一个研究领域的一个研究领域的一个研究领域的一个研究领域的一个研究领域的一个研究领域的一个研究领域的一个研究领域的一个研究领域的一个研究领域的一个研究领域，一个研究领域，一个关于一个研究领域的J95G4VAO+qUsgJGwC++SKp4.F/D/D/D/D/D/D/D/D/D/D/3三级社区社区社区（10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 33WLEAOTHQQBIOZD4JTOANbyEJ/w9fnNBOzkTAOszxmBP+5+SNK2TWNWAAAAAAAELFTKSUQMCC
