Question

我正在使用JavaEmail API发送电子邮件但遇到问题。

我收到以下错误。

04-17 21:10:09.470: E/AndroidRuntime(28920): java.lang.NoClassDefFoundError: nz.co.devicelocation.EmailSender$1

这是我的SendEmail类，

import java.util.Properties;

import javax.mail.Authenticator;
import javax.mail.Message;
import javax.mail.MessagingException;
import javax.mail.PasswordAuthentication;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;

import android.util.Log;

public class EmailSender {

private static final String FROM = "location@gmail.com";
private static final String LOGIN = "location@gmail.com";
private static final String PASSWORD = "passthrough";
private static final String SUBJECT = "Your android device Location";

public EmailSender(String val){
    Log.d("EmailSender", "inside constructor of emailsender");
}

public void sendEmail(){
    Log.d("EmailSender", "Email Sent!@@@@@@@@@@");
    Properties props = new Properties();
    props.put("mail.smtp.auth", "true");
    props.put("mail.smtp.starttls.enable", "true");
    props.put("mail.smtp.host", "smtp.gmail.com");
    props.put("mail.smtp.port", "587");

    Session session = Session.getInstance(props,
            new Authenticator() {       <<<<<<<-------------Error is happening here
                @Override
                protected PasswordAuthentication getPasswordAuthentication() {
                    return new PasswordAuthentication(LOGIN, PASSWORD);
                }
            });
    try {
        Message message = new MimeMessage(session);
        message.setFrom(new InternetAddress(FROM));
        message.setRecipients(Message.RecipientType.TO,
                InternetAddress.parse("testemailrun@gmail.com"));
        message.setSubject(SUBJECT);
        message.setText("Testing from android");
        Transport.send(message);
        Log.d("EmailSender", "EmailSent");

    } catch (MessagingException e) {
        //If  any exception is thrown user is warned.
        Log.d("EmailSender", e.getMessage());
    }
}

我似乎在以下代码中收到错误

 Session session = Session.getInstance(props,
            new Authenticator() {       <<<<<<<-------------Error is happening here
                @Override
                protected PasswordAuthentication getPasswordAuthentication() {
                    return new PasswordAuthentication(LOGIN, PASSWORD);
                }
            });

我已经将mail.jar添加到我的库中，但验证者仍然会抛出错误。

有什么遗漏吗？
