How to do it:
1. Download the java mail library: https://code.google.com/p/javamail-android/downloads/list
2. Add the corresponding permissions in the AndroidManifest.xml file:
3.Create a class MailHelper and copy the following code:
import java.io.File;
import java.util.Properties;
import javax.activation.DataHandler;
import javax.activation.FileDataSource;
import javax.mail.BodyPart;
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.MimeBodyPart;
import javax.mail.internet.MimeMessage;
import javax.mail.internet.MimeMultipart;
public class MailHelper {
private String originEmail;
private String originPassword;
private String destinationEmail;
private String auth;
private String sslEnable;
private String smtpHost;
private String smtpPort;
public Mail(String originEmail,String originPassword,String destinationEmail){
this.originEmail=originEmail;
this.originPassword=originPassword;
this.destinationEmail=destinationEmail;
this.auth="true";
this.sslEnable="true";
this.smtpHost="smtp.gmail.com";
this.smtpPort="587";
}
public boolean send(String attachmentFilePath){
boolean noError=true;
final String username=originEmail;
final String password=originPassword;
Properties props = new Properties();
props.put("mail.smtp.auth", auth);
props.put("mail.smtp.starttls.enable", sslEnable);
props.put("mail.smtp.host", smtpHost);
props.put("mail.smtp.port", smtpPort);
Session session = Session.getInstance(props,
new javax.mail.Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(username, password);
}
});
try {
BodyPart text=new MimeBodyPart();
text.setText("Text");
BodyPart bodyAttachment=new MimeBodyPart();
bodyAttachment.setDataHandler(new DataHandler(new FileDataSource(attachmentFilePath)));
bodyAttachment.setFileName("Attachment");
MimeMultipart mm=new MimeMultipart();
mm.addBodyPart(text);
mm.addBodyPart(bodyAttachment);
MimeMessage message=new MimeMessage(session);
message.setFrom(new InternetAddress(originEmail));
message.setRecipients(Message.RecipientType.TO,
InternetAddress.parse(destinationEmail));
message.setSubject("Subject");
message.setContent(mm);
Transport.send(message);
} catch (MessagingException e) {
noError=false;
throw new RuntimeException(e);
}
return noError;
}
}
4.Place the following code in a separate thread, because this a time consuming task that can potentially freeze your UI. You can usean AsynTask for this purpose, for example.
import java.io.File;
MailHelper mail=new MailHelper("origin@gmail.com","originPassword"
,"destination@gmail.com");
Boolean noError=m.send(fileAbsolutePath);
