[DIY] How to Send Email With JavaMail On Android

Nah, Sekarang bagaimana caranya menggunakan JavaMail di Android ? Semoga tutorial berikut membantu
Pertama download dulu file pendukungnya alias library di http://code.google.com/p/javamail-android/

bentar tak mindahin kucing ku dulu .......

5 menit kemudian

nah sekarang saya mencoba mengirim email menggunakan android tanpa menggunakan Intent. Yups, saya menggunakan JavaMail .


1. Buat Project Android dulu.

2. Buat tampilan sederhana. Disini saya membuat simple dengan membuat satu button yang authentication, subject email dan isinya di deklarasikan pada sourcecode.

<linearlayout android:layout_height="fill_parent" android:layout_width="fill_parent" android:orientation="vertical" xmlns:android="http://schemas.android.com/apk/res/android">
<button android:id="@+id/send" android:layout_height="fill_parent" android:layout_width="fill_parent" android:text="send">
<linearlayout android:id="@+id/linearLayout1" android:layout_height="wrap_content" android:layout_width="fill_parent">
</linearlayout></button><button android:id="@+id/send" android:layout_height="wrap_content" android:layout_width="wrap_content" android:text="Button"></button>
</linearlayout>

3. Tambahkan library yang sudah anda download di http://code.google.com/p/javamail-android/ tadi pada project android anda.

4. Selanjutnya kita membuat GMAIL sender

yang isinya sebagai berikut

package com.mailsender.adtmail;

import javax.activation.DataHandler;   
import javax.activation.DataSource;   
import javax.mail.Message;   
import javax.mail.PasswordAuthentication;   
import javax.mail.Session;   
import javax.mail.Transport;   
import javax.mail.internet.InternetAddress;   
import javax.mail.internet.MimeMessage;   
import java.io.ByteArrayInputStream;   
import java.io.IOException;   
import java.io.InputStream;   
import java.io.OutputStream;   
import java.security.Security;   
import java.util.Properties;   

public class GMailSender extends javax.mail.Authenticator {   
    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");   
        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);   
    }   

    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");   
        }   
    }   
}  

5. Buat Class baru lagi JSSEProvider

package com.mailsender.adtmail;

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

public final class JSSEProvider extends Provider {

    /**
	 * 
	 */
	private static final long serialVersionUID = 1L;

	public JSSEProvider() {
        super("HarmonyJSSE", 1.0, "Harmony JSSE Provider");
        AccessController.doPrivileged(new java.security.PrivilegedAction() {
            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;
            }
        });
    }
}

6. Yang terakhir Buat Class Activitynya 

package com.mailsender.adtmail;

import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.Button;

public class MailSenderActivity extends Activity {

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        final Button send = (Button) this.findViewById(R.id.send);
        send.setOnClickListener(new View.OnClickListener() {

            public void onClick(View v) {
                // TODO Auto-generated method stub

                try {   
                    GMailSender sender = new GMailSender("zeatnoz@gmail.com", "eravagansa1989adem2o");
                    sender.sendMail("This is Subject",   
                            "This is Body",   
                            "zeatnoz@gmail.com",   
                            "sudarq@yahoo.co.id");   
                } catch (Exception e) {   
                    Log.e("SendMail", e.getMessage(), e);   
                } 

            }
        });

    }
}
