android中使用javamail發送郵件附件

[java] 使用javamail必須先下載3個JAR包並導入工程 activation.jar   additonnal.jar   mail.jar 
 
導入方法為: project->properties->java build path->libraries->add external jars 
 
然後在android項目中添加網絡訪問權限 
 
 <uses-permission android:name="android.permission.INTERNET"></uses-permission> 
 
最後在程序中加載如下包 
 
 
import android.app.Activity; 
import android.os.Bundle; 
import android.util.Log; 
 
 
import java.util.Properties; 
import javax.activation.DataHandler; 
import javax.activation.FileDataSource; 
import javax.mail.*; 
import javax.mail.internet.*; 
import javax.mail.PasswordAuthentication; 
 
 
調用函數代碼如下  
 
 
 
class MyAuthenticator 
      extends javax.mail.Authenticator { 
        private String strUser; 
        private String strPwd; 
        public MyAuthenticator(String user, String password)  
        { 
        this.strUser = user; 
        this.strPwd = password; 
        } 
 
 
    protected PasswordAuthentication getPasswordAuthentication()  
    { 
      return new PasswordAuthentication(strUser, strPwd); 
    } 
} 
 
 
 
public void send_mail_file(String str_to_mail,String str_from_mail,String str_smtp,String str_user,String str_pass,String str_title,String str_body,String str_file_path) 
    { 
        Log.v("lengfeng","send_mail_file"); 
 
 
        String host = str_smtp;   //發件人使用發郵件的電子信箱服務器  
        String from = str_from_mail;    //發郵件的出發地（發件人的信箱）  
        String to   = str_to_mail;   //發郵件的目的地（收件人信箱）  
 
 
        Log.v("lengfeng",str_smtp); 
        Log.v("lengfeng",str_from_mail); 
        Log.v("lengfeng",str_to_mail); 
         
        Properties props = System.getProperties();// Get system properties  
 
 
         
        props.put("mail.smtp.host", host);// Setup mail server  
 
 
         
        props.put("mail.smtp.auth", "true"); //這樣才能通過驗證  
 
 
        MyAuthenticator myauth = new MyAuthenticator(str_user, str_pass);// Get session  
         
        Session session = Session.getDefaultInstance(props, myauth); 
 
 
        
        MimeMessage message = new MimeMessage(session); // Define message  
        
 
 
        
        try { 
            message.setFrom(new InternetAddress(from)); // Set the from address  
        } catch (AddressException e) { 
            e.printStackTrace(); 
        } catch (MessagingException e) { 
            e.printStackTrace(); 
        } 
 
 
         
        try { 
            message.addRecipient(Message.RecipientType.TO,new InternetAddress(to));// Set the to address  
        } catch (AddressException e) { 
            e.printStackTrace(); 
        } catch (MessagingException e) { 
            e.printStackTrace(); 
        } 
 
 
         
        try { 
            message.setSubject(str_title);// Set the subject  
        } catch (MessagingException e) { 
            e.printStackTrace(); 
        } 
 
 
         
        try { 
            message.setText(str_body);// Set the content  
        } catch (MessagingException e) { 
            e.printStackTrace(); 
        } 
 
 
         
        MimeBodyPart attachPart = new MimeBodyPart();  
        FileDataSource fds = new FileDataSource(str_file_path); //打開要發送的文件  
        try { 
            attachPart.setDataHandler(new DataHandler(fds)); 
        } catch (MessagingException e) { 
            e.printStackTrace(); 
        }  
        try { 
            attachPart.setFileName(fds.getName()); 
        } catch (MessagingException e) { 
            e.printStackTrace(); 
        }  
         
         
        MimeMultipart allMultipart = new MimeMultipart("mixed"); //附件  
        try { 
            allMultipart.addBodyPart(attachPart);//添加  
        } catch (MessagingException e) { 
            e.printStackTrace(); 
        }  
        try { 
            message.setContent(allMultipart); 
        } catch (MessagingException e) { 
            e.printStackTrace(); 
        }  
        try { 
            message.saveChanges(); 
        } catch (MessagingException e) { 
            e.printStackTrace(); 
        }  
 
 
          try { 
            Transport.send(message);//開始發送  
        } catch (MessagingException e) { 
            e.printStackTrace(); 
        }
