我正在尝试在 Android 中使用 GmailSender 附加 SD 文件。
我有这个：通过 GMailSender 发送带有附件的电子邮件？
我检查了文件是否存在，但邮件无法正确发送。没有附加文件的相同方法运行正常。
可能是什么问题？
谢谢。
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 类：

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);
}

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 {

message.setSubject(subject);
message.setDataHandler(handler);
if(attachment!=null){
MimeBodyPart mbp1 = new MimeBodyPart();
mbp1.setText(body);

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) {

this.data = data;
}
public void setType(String type) {

public String getContentType() {
if (type == null)
return "application/octet-stream";
else

我的例外是：
