安卓收發郵件怎樣實作？經過一番折騰，終于實作了，記錄一下，以免忘記。
要實作收發郵件，要在libs檔案夾中加入三個jar包。
activation.jar
additionnal.jar
mail.jar
自己可以去網上下載下傳。
複制以下5個檔案就可以測試了。
第一個 MailSenderInfo.java
package com.aj.mail;
import java.util.Properties;
public class MailSenderInfo {
private String mailServerHost;
private String mailServerPort = "25";
private String fromAddress;
private String toAddress;
private String userName;
private String password;
private boolean validate = true;
private String subject;
private String content;
private String[] attachFileNames;
public Properties getProperties() {
Properties p = new Properties();
p.put("mail.smtp.host", this.mailServerHost);
p.put("mail.smtp.port", this.mailServerPort);
p.put("mail.smtp.auth", validate ? "true" : "false");
return p;
}
public String getMailServerHost() {
return mailServerHost;
}
public void setMailServerHost(String mailServerHost) {
this.mailServerHost = mailServerHost;
}
public String getMailServerPort() {
return mailServerPort;
}
public void setMailServerPort(String mailServerPort) {
this.mailServerPort = mailServerPort;
}
public boolean isValidate() {
return validate;
}
public void setValidate(boolean validate) {
this.validate = validate;
}
public String[] getAttachFileNames() {
return attachFileNames;
}
public void setAttachFileNames(String[] fileNames) {
this.attachFileNames = fileNames;
}
public String getFromAddress() {
return fromAddress;
}
public void setFromAddress(String fromAddress) {
this.fromAddress = fromAddress;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getToAddress() {
return toAddress;
}
public void setToAddress(String toAddress) {
this.toAddress = toAddress;
}
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
public String getSubject() {
return subject;
}
public void setSubject(String subject) {
this.subject = subject;
}
public String getContent() {
return content;
}
public void setContent(String textContent) {
this.content = textContent;
}
}
第二個 MyAuthenticator.java
package com.aj.mail;
import javax.mail.Authenticator;
import javax.mail.PasswordAuthentication;
public class MyAuthenticator extends Authenticator
{
String userName=null;
String password=null;
public MyAuthenticator()
{
}
public MyAuthenticator(String username, String password)
{
this.userName = username;
this.password = password;
}
protected PasswordAuthentication getPasswordAuthentication()
{
return new PasswordAuthentication(userName, password);
}
}
第三個 ReceiveMail
package com.aj.mail;
import com.tool.App;
import com.tool.Constant;
import java.util.Date;
import java.util.Properties;
import java.util.logging.Handler;
import javax.mail.Address;
import javax.mail.Folder;
import javax.mail.Message;
import javax.mail.Session;
import javax.mail.Store;
import org.json.JSONObject;
public class ReceiveMail {
//收件人位址
public static String recipientAddress = Constant.MailAddress;
//收件人賬戶名
public static String recipientAccount = Constant.MailUser;
//收件人賬戶密碼
public static String recipientPassword = Constant.MailPassWord;
public static void receive(Handler handlerMail) throws Exception {
//1、連接配接郵件伺服器的參數配置
Properties props = new Properties();
//設定傳輸協定
props.setProperty("mail.store.protocol", "pop3");
//設定收件人的POP3伺服器
props.setProperty("mail.pop3.host", "pop3.139.com");
//2、建立定義整個應用程式所需的環境資訊的 Session 對象
Session session = Session.getInstance(props);
//設定調試資訊在控制台列印出來
//session.setDebug(true);
Store store = session.getStore("pop3");
//連接配接收件人POP3伺服器
store.connect("pop3.139.com", recipientAccount, recipientPassword);
//獲得使用者的郵件賬戶，注意通過pop3協定擷取某個郵件夾的名稱隻能為inbox
Folder folder = store.getFolder("inbox");
//設定對郵件賬戶的通路權限
folder.open(Folder.READ_WRITE);
//得到郵件賬戶的所有郵件資訊
Message [] messages = folder.getMessages();
for(int i = 0 ; i < messages.length ; i++){
//獲得郵件主題
String subject = messages[i].getSubject();
//獲得郵件發件人
Address[] from = messages[i].getFrom();
//擷取郵件内容（包含郵件内容的html代碼）
String content = (String) messages[i].getContent();
App.wt(content);
Date d=messages[i].getReceivedDate();
long time=d.getTime();
long now = System.currentTimeMillis();
long cha=now-time;
if(cha<60*60*1000){
if(content.contains("内容")&&subject.equals("測試")){
JSONObject js=new JSONObject();
js.put("time",0);
android.os.Message msg=new android.os.Message();
msg.obj = js;
msg.what = 0;
//這裡用handler傳過去處理
}
}
}
//關閉郵件夾對象
folder.close(true);
//關閉連接配接對象
store.close();
}
}
下面這個是活動，測試發送郵件用
package com.aj.mail;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import com.aj.nongmao.R;
import com.tool.App;
import com.tool.Constant;
import com.tool.Err;
public class SendEmailActivity extends Activity {
private Button send;
private EditText userid;
private EditText password;
private EditText from;
private EditText to;
private EditText subject;
private EditText body;
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.mail2);
send = findViewById(R.id.send);
userid = findViewById(R.id.userid);
password = findViewById(R.id.password);
from = findViewById(R.id.from);
to = findViewById(R.id.to);
subject = findViewById(R.id.subject);
body = findViewById(R.id.body);
send.setText("内容");
userid.setText(Constant.MailUser);
password.setText(Constant.MailPassWord);
from.setText(Constant.MailAddress);
to.setText("[email protected]");
subject.setText("标題");
body.setText("内容");
send.setOnClickListener(new View.OnClickListener()
{
@Override
public void onClick(View v)
{
new Thread(
new Runnable(){
@Override
public void run() {
try
{
MailSenderInfo mailInfo = new MailSenderInfo();
mailInfo.setMailServerHost("smtp.139.com");
mailInfo.setMailServerPort("25");
mailInfo.setValidate(true);
mailInfo.setUserName(userid.getText().toString());
mailInfo.setPassword(password.getText().toString());
mailInfo.setFromAddress(from.getText().toString());
mailInfo.setToAddress(to.getText().toString());
mailInfo.setSubject(subject.getText().toString());
mailInfo.setContent(body.getText().toString());
SimpleMailSender sms = new SimpleMailSender();
sms.sendTextMail(mailInfo);
}
catch (Exception e) {
Err.getErrStr(e);
}
}
}).start();
// TODO Auto-generated method stub
}
});
}
}
最後一個
package com.aj.mail;
import java.util.Date;
import java.util.Properties;
import javax.mail.Address;
import javax.mail.BodyPart;
import javax.mail.Message;
import javax.mail.MessagingException;
import javax.mail.Multipart;
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;
import com.tool.Err;
public class SimpleMailSender
{
public void sendTextMail(final MailSenderInfo mailInfo)
{
new Thread(
new Runnable(){
@Override
public void run() {
MyAuthenticator authenticator = null;
Properties pro = mailInfo.getProperties();
if (mailInfo.isValidate())
{
authenticator = new MyAuthenticator(mailInfo.getUserName(), mailInfo.getPassword());
}
Session sendMailSession = Session.getDefaultInstance(pro,authenticator);
try
{
Message mailMessage = new MimeMessage(sendMailSession);
Address from = new InternetAddress(mailInfo.getFromAddress());
mailMessage.setFrom(from);
Address to = new InternetAddress(mailInfo.getToAddress());
mailMessage.setRecipient(Message.RecipientType.TO,to);
mailMessage.setSubject(mailInfo.getSubject());
mailMessage.setSentDate(new Date());
String mailContent = mailInfo.getContent();
mailMessage.setText(mailContent);
Transport.send(mailMessage);
//return true;
}
catch (MessagingException ex)
{
Err.getErrStr(ex);
}
}
}).start();
//return false;
}
public static boolean sendHtmlMail(MailSenderInfo mailInfo)
{
MyAuthenticator authenticator = null;
Properties pro = mailInfo.getProperties();
if (mailInfo.isValidate())
{
authenticator = new MyAuthenticator(mailInfo.getUserName(), mailInfo.getPassword());
}
Session sendMailSession = Session.getDefaultInstance(pro,authenticator);
try {
Message mailMessage = new MimeMessage(sendMailSession);
Address from = new InternetAddress(mailInfo.getFromAddress());
mailMessage.setFrom(from);
Address to = new InternetAddress(mailInfo.getToAddress());
// Message.RecipientType.TO
mailMessage.setRecipient(Message.RecipientType.TO,to);
mailMessage.setSubject(mailInfo.getSubject());
mailMessage.setSentDate(new Date());
Multipart mainPart = new MimeMultipart();
BodyPart html = new MimeBodyPart();
html.setContent(mailInfo.getContent(), "text/html; charset=utf-8");
mainPart.addBodyPart(html);
mailMessage.setContent(mainPart);
Transport.send(mailMessage);
return true;
} catch (MessagingException ex) {
ex.printStackTrace();
}
return false;
}
}
注意：password不是登入郵箱的密碼，到郵箱去擷取密鑰。
