Android下使用activation发送邮件

1. 添加对如下jar包的引用activation.jar， additionnal.jar， mail.jar

2. 添加访问internet的权限

<uses-permission android:name="android.permission.INTERNET"></uses-permission>

 

3. 实现如下两个类：

import java.security.AccessController;
import java.security.Provider;

public class JSSEProvider extends Provider{

	public JSSEProvider() { 
        super("HarmonyJSSE", 1.0, "Harmony JSSE Provider"); 
        AccessController.doPrivileged(new java.security.PrivilegedAction<Void>() { 
            public Void run() { 
                put("SSLContext.TLS", 
                        "org.apache.harmony.xnet.provider.jsse.SSLContextImpl"); 
                put("Alg.Alias.SSLContext.TLSv1", "TLS"); 
                put("KeyManagerFactory.X509", 
                        "org.apache.harmony.xnet.provider.jsse.KeyManagerFactoryImpl"); 
                put("TrustManagerFactory.X509", 
                        "org.apache.harmony.xnet.provider.jsse.TrustManagerFactoryImpl"); 
                return null; 
            } 
        }); 
    } 
}

	private String mailhost = "smtp.gmail.com";    
    private String user;    
    private String password;    
    private Session session;  
    
    static {    
        Security.addProvider(new JSSEProvider());    
    } 
    
    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");

        session = Session.getDefaultInstance(props, this);    
    }    
 
    protected PasswordAuthentication getPasswordAuthentication() {    
        return new PasswordAuthentication(user, password);    
    }    
 
    public synchronized void sendMail(String subject, String body, String sender, String recipients) throws Exception {    
        try{ 
        MimeMessage message = new MimeMessage(session);    
        DataHandler handler = new DataHandler(new ByteArrayDataSource(body.getBytes(), "text/plain"));    
        message.setSender(new InternetAddress(sender));    
        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 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) {    
            super();    
            this.data = data;    
        }    
 
        public void setType(String type) {    
            this.type = type;    
        }    
 
        public String getContentType() {    
            if (type == null)    
                return "application/octet-stream";    
            else   
                return type;    
        }    
 
        public InputStream getInputStream() throws IOException {    
            return new ByteArrayInputStream(data);    
        }    
 
        public String getName() {    
            return "ByteArrayDataSource";    
        }    
 
        public OutputStream getOutputStream() throws IOException {    
            throw new IOException("Not Supported");    
        }    
    }
}

 

4. 使用方法：

public class SendEmailTestActivity extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        
        Button btnSend = (Button)findViewById(R.id.btnSend);
        btnSend.setOnClickListener( new OnClickListener(){

			@Override
			public void onClick(View arg0) {
				try {   
                	//发送方的邮箱名及密码。
                    GMailSender sender = new GMailSender("*******@gmail.com", "*******"); 
                    sender.sendMail("This is Subject",    //主题
                            "This is Body",    //正文
                            "[email protected]",  //发送人  
                            "*******@gmail.com"); //收件人,不一定非得gmail其他邮箱比如163，qq邮箱都行。
                    Toast.makeText(getBaseContext(), "发送成功！",	Toast.LENGTH_LONG).show();
                } catch (Exception e) {    
                    Log.e("SendMail", e.getMessage(), e);   
                    Toast.makeText(getBaseContext(), "发送失败"+e.getMessage(),	Toast.LENGTH_LONG).show();                	
                } 
			}
        });
    }
}
