好的我会提供一些样本来跟进
在一个活动中，您启动了一个摄像头，意图捕获像这样的图像
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, CAMERA_REQUEST);
在同一个活动的onActivityResult内，您将设置缩略图并将其写入外部存储空间
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，您将编写类似这样的内容
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"));
希望这可以帮助您完成任务。

尝试使用此代码
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); }}

尝试使用image data-url。它类似于普通文本，您可以将其放在<img>标记中，例如：
<img src="data-url">
data-url是：
