Here is a screen shot.
The main activity is pretty simple
package org.apache.android.mail;
import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
public class SendMail extends Activity {
/**
* Called with the activity is first created.
*/
@Override
public void onCreate(Bundle icicle) {
super.onCreate(icicle);
setContentView(R.layout.main);
final Button send = (Button) this.findViewById(R.id.send);
final EditText userid = (EditText) this.findViewById(R.id.userid);
final EditText password = (EditText) this.findViewById(R.id.password);
final EditText from = (EditText) this.findViewById(R.id.from);
final EditText to = (EditText) this.findViewById(R.id.to);
final EditText subject = (EditText) this.findViewById(R.id.subject);
final EditText body = (EditText) this.findViewById(R.id.body);
send.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
GMailSender sender = new GMailSender(userid.getText().toString(), password.getText().toString());
try {
sender.sendMail(subject.getText().toString(),
body.getText().toString(),
from.getText().toString(),
to.getText().toString());
} catch (Exception e) {
Log.e("SendMail", e.getMessage(), e);
}
}
});
}
}
The GMail Sender code is from here
package org.apache.android.mail;
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 org.apache.harmony.xnet.provider.jsse.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 {
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);
}
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");
}
}
}
Notes
- We use activation-1.1.jar and mail-1.4.jar from SUN
- Picked up a few classes in java.awt.datatransfer package from Apache Harmony SVN (and stripped them down)
- Picked up the ByteArrayDataSource class from Apache Axis
- build.xml adds the 2 jars and the additional harmony/axis classes into the classes.dex as well

Hi,
I copied the code above into my android program using Eclipse, and the code didn’t have any compilation problem. However, when I run it, I get the following error message:
java.lang.NoClassDefFoundError: javax/activation/DataHandler
I have both the activation-1.1.jar and mail-1.4.jar in my build path. Can someone help me out? I have been trying to solve this for one week already. Thanks!

I can run its on eclipse.
I build new project and copy all source file to project.
after that you can not run it. Because name of activity(start activity) does not match. So I change Activity class name to match with name of start activity in open dialog.
RoSippA
May 6, 2008 at 1:19 am
mcluucy (and others):
The NoClassDefFoundError results from android’s lack of java.awt.datatransfer classes. In order to gain access to message contents in javamail (sending or receiving) you need to have the DataHandler class that is in activation.jar; however, this class will fail to link if specific classes from java.awt.datatransfer are not present. Hence, the error messages indicate that DataHandler cannot be loaded, even though it is in the classpath.
The provided .zip contains (as indicated in the notes after the above source code) a few files from the Apache Harmony implementation of java (presumably cut to remove compilation errors), which can be copied into a project. However, note that if you indend to use these files to gain read access to a MimeMessage (e.g., IMAP client), I’ve found that they only provide an InputStream, and do not allow you to cast .getContent as a String or Multipart. I imagine the relevant awt classes required for these DataHandlers can be similarly acquired.
Will
May 8, 2008 at 3:59 am
Also, note that an implementation of ByteArrayDataSource was taken from Apache Axis to define the DataHandler required to send the mail (as shown in the above source code). A similar technique may be useful in retrieving a String or Mailpart with .getContent()

farah
May 15, 2008 at 9:01 am
I discovered (a while ago, but forgot to post a comment here) the cause to the .getContent() error described above. When the activation.jar and mail.jar archives are imported into Android, the META-INF directories containing the mailcap entries are stripped. When the classes look at the MIME type on the content, it doesn’t find a known handler because one is never defined.

April 2, 2009 at 4:14 pm
I can’t see how this code works, when I run, both on the device or emulator it fails with a java.lang.VerifyError This is because javax.mail depends on javax.activation package. The DataHandler class in activation uses an interface from awt which is obviously not included in the dalvik system.
Before the exception is thrown I see
Failed resolving Ljavax/activation/DataHandler; interface 178 ‘Ljava/awt/datatransfer/Transferable;’
So, how do you get javax.mail to run without this dependency?

Hey saifuctg thanks for the SendMail rar, it doesnt seem to be complete though…its missing the extra harmony/axis classes that are supposed to be added to the dex file….dont suppose anyone still has a copy of them lying around anywhere?

Hey guys managed to get this working on 1.5 and 1.1 firmware. unfortunately it ended up not being very useful for me (I wanted to use gmail as a mail relay – unfortunately Google overwrites the From header whenever you send a mail from an authenticated account)…
Anyways you guys might still find a use for it. I have created two jar files, additional.jar contains the missing datatransfer classes and custom_activation.jar is a customized set of activation classes which reference the local data transfer classes rather than the system default ones.
You can find both of these jar files at:

Hi,
“Ljavax/activation/DataHandler” problem is still observed. can anybody give any suggesion to solve this problem. whether the new .jar files (custom_activation, additional.jar) will solve this issue.
can you attach those .jar files again. only

Hi Mark, how exactly are you trying to use the libraries? could you post the code snippet thats actually throwing that exception?
My initial thoughts are that your using a corrupt version of mail.jar…try using the one on my site (http://jamesgrafton.com/Android/mail.jar)
