现在一般很少有用Android原生app发送邮件的需求,但是前段时间公司项目需要在Android app 内部发送邮件,于是就在网上收集资料并整理了一个Demo。虽然最后这个需求被减掉了,但是我这里还是把Demo的内容给大家分享一下。

Android实现发送邮件,首先需要依赖additional.jar、mail.jar和activation.jar这3个jar包。Google提供了下载地址: 。下载后添加到依赖(这里我就不详细说明了)。

1、创建MailInfo类,来代表一个即将被发送的邮件
package com.shidian.mail;import java.util.Properties;public class MailInfo { private String mailServerHost;// 发送邮件的服务器的IP private String mailServerPort;// 发送邮件的服务器的端口 private String fromAddress;// 邮件发送者的地址 private String toAddress; // 邮件接收者的地址 private String userName;// 登陆邮件发送服务器的用户名 private String password;// 登陆邮件发送服务器的密码 private boolean validate = true;// 是否需要身份验证 private String subject;// 邮件主题 private String content;// 邮件的文本内容 private String[] attachFileNames;// 邮件附件的文件名 /** * 获得邮件会话属性 */ 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; }}
2、创建认证类MyAuthenticator
package com.shidian.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); }}
3、创建邮件发送类MailSender
package com.shidian.mail;import android.util.Log;import java.io.File;import java.util.Date;import java.util.Properties;import javax.activation.DataHandler;import javax.activation.FileDataSource;import javax.mail.Address;import javax.mail.Authenticator;import javax.mail.BodyPart;import javax.mail.Message;import javax.mail.MessagingException;import javax.mail.Multipart;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;import javax.mail.internet.MimeUtility;/** * 发送器 */public class MailSender { /** * 以文本格式发送邮件 * @param mailInfo 待发送的邮件的信息 */ public boolean sendTextMail(final MailInfo mailInfo) { // 判断是否需要身份认证 MyAuthenticator authenticator = null; Properties pro = mailInfo.getProperties(); if (mailInfo.isValidate { // 如果需要身份认证,则创建一个密码验证器 authenticator = new MyAuthenticator(mailInfo.getUserName(), mailInfo.getPassword; } // 根据邮件会话属性和密码验证器构造一个发送邮件的session Session sendMailSession = Session.getDefaultInstance(pro, authenticator);// Session sendMailSession = Session.getInstance(pro, new Authenticator() {// @Override// protected PasswordAuthentication getPasswordAuthentication() {// return new PasswordAuthentication(mailInfo.getUserName(),mailInfo.getPassword;// }// }); try { // 根据session创建一个邮件消息 Message mailMessage = new MimeMessage(sendMailSession); // 创建邮件发送者地址 Address from = new InternetAddress(mailInfo.getFromAddress; // 设置邮件消息的发送者 mailMessage.setFrom; // 创建邮件的接收者地址,并设置到邮件消息中 Address to = new InternetAddress(mailInfo.getToAddress; mailMessage.setRecipient(Message.RecipientType.TO, to); // 设置邮件消息的主题 mailMessage.setSubject(mailInfo.getSubject; // 设置邮件消息发送的时间 mailMessage.setSentDate(new Date; // 设置邮件消息的主要内容 String mailContent = mailInfo.getContent(); mailMessage.setText(mailContent); // 发送邮件 Transport.send(mailMessage); return true; } catch (MessagingException ex) { ex.printStackTrace(); } return false; } /** * 以HTML格式发送邮件 * @param mailInfo 待发送的邮件信息 */ public static boolean sendHtmlMail(MailInfo mailInfo) { // 判断是否需要身份认证 MyAuthenticator authenticator = null; Properties pro = mailInfo.getProperties(); // 如果需要身份认证,则创建一个密码验证器 if (mailInfo.isValidate { authenticator = new MyAuthenticator(mailInfo.getUserName(), mailInfo.getPassword; } // 根据邮件会话属性和密码验证器构造一个发送邮件的session Session sendMailSession = Session.getDefaultInstance(pro, authenticator); try { // 根据session创建一个邮件消息 Message mailMessage = new MimeMessage(sendMailSession); // 创建邮件发送者地址 Address from = new InternetAddress(mailInfo.getFromAddress; // 设置邮件消息的发送者 mailMessage.setFrom; // 创建邮件的接收者地址,并设置到邮件消息中 Address to = new InternetAddress(mailInfo.getToAddress; // Message.RecipientType.TO属性表示接收者的类型为TO mailMessage.setRecipient(Message.RecipientType.TO, to); // 设置邮件消息的主题 mailMessage.setSubject(mailInfo.getSubject; // 设置邮件消息发送的时间 mailMessage.setSentDate(new Date; // MiniMultipart类是一个容器类,包含MimeBodyPart类型的对象 Multipart mainPart = new MimeMultipart(); // 创建一个包含HTML内容的MimeBodyPart BodyPart html = new MimeBodyPart(); // 设置HTML内容 html.setContent(mailInfo.getContent(), "text/html; charset=utf-8"); mainPart.addBodyPart; // 将MiniMultipart对象设置为邮件内容 mailMessage.setContent; // 发送邮件 Transport.send(mailMessage); return true; } catch (MessagingException ex) { ex.printStackTrace(); } return false; } /** * 发送带附件的邮件 * @param info * @return */ public boolean sendFileMail(MailInfo info, File file){ Message attachmentMail = createAttachmentMail(info,file); try { Transport.send(attachmentMail); return true; } catch (MessagingException e) { e.printStackTrace(); return false; } } /** * 创建带有附件的邮件 * @return */ private Message createAttachmentMail(final MailInfo info, File file) { //创建邮件 MimeMessage message = null; Properties pro = info.getProperties(); try { Session sendMailSession = Session.getInstance(pro, new Authenticator() { @Override protected PasswordAuthentication getPasswordAuthentication() { return new PasswordAuthentication(info.getUserName(),info.getPassword; message = new MimeMessage(sendMailSession); // 设置邮件的基本信息 //创建邮件发送者地址 Address from = new InternetAddress(info.getFromAddress; //设置邮件消息的发送者 message.setFrom; //创建邮件的接受者地址,并设置到邮件消息中 Address to = new InternetAddress(info.getToAddress; //设置邮件消息的接受者, Message.RecipientType.TO属性表示接收者的类型为TO message.setRecipient(Message.RecipientType.TO, to); //邮件标题 message.setSubject(info.getSubject; // 创建邮件正文,为了避免邮件正文中文乱码问题,需要使用CharSet=UTF-8指明字符编码 MimeBodyPart text = new MimeBodyPart(); text.setContent(info.getContent(), "text/html;charset=UTF-8"); // 创建容器描述数据关系 MimeMultipart mp = new MimeMultipart(); mp.addBodyPart; // 创建邮件附件 MimeBodyPart attach = new MimeBodyPart(); FileDataSource ds = new FileDataSource; DataHandler dh = new DataHandler; attach.setDataHandler; attach.setFileName(MimeUtility.encodeText(dh.getName; mp.addBodyPart; mp.setSubType; message.setContent; message.saveChanges(); } catch (Exception e) { Log.e("TAG", "创建带附件的邮件失败"); e.printStackTrace(); } // 返回生成的邮件 return message; }}

这里举例发送文本邮件和带附件的邮件

package teprinciple.yang.sendmaildemo;import android.os.Environment;import android.support.v7.app.AppCompatActivity;import android.os.Bundle;import android.view.View;import android.widget.EditText;import com.shidian.mail.SendMailUtil;import java.io.File;import java.io.FileNotFoundException;import java.io.FileOutputStream;import java.io.IOException;import java.io.OutputStream;public class MainActivity extends AppCompatActivity { private EditText editText; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); editText =  findViewById(R.id.toAddEt); } public void senTextMail(View view) { SendMailUtil.send(editText.getText().toString; } public void sendFileMail(View view) { File file = new File(Environment.getExternalStorageDirectory() File.separator "test.txt"); OutputStream os = null; try { os = new FileOutputStream; String str = "hello world"; byte[] data = str.getBytes(); os.write; } catch (FileNotFoundException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); }finally{ try { if (os != null)os.close(); } catch (IOException e) { } } SendMailUtil.send(file,editText.getText().toString; }}

package com.shidian.mail;import android.support.annotation.NonNull;import java.io.File;/** * Created by Administrator on 2017/4/10. */public class SendMailUtil { //qq private static final String HOST = "smtp.qq.com"; private static final String PORT = "587"; private static final String FROM_ADD = "teprinciple@foxmail.com"; //发送方邮箱 private static final String FROM_PSW = "lfrlpganzjrwbeci";//发送方邮箱授权码// //163// private static final String HOST = "smtp.163.com";// private static final String PORT = "465"; //或者465 994// private static final String FROM_ADD = "teprinciple@163.com";// private static final String FROM_PSW = "teprinciple163";//// private static final String TO_ADD = "2584770373@qq.com"; public static void send(final File file,String toAdd){ final MailInfo mailInfo = creatMail; final MailSender sms = new MailSender(); new Thread(new Runnable() { @Override public void run() { sms.sendFileMail(mailInfo,file); } }).start(); } public static void send(String toAdd){ final MailInfo mailInfo = creatMail; final MailSender sms = new MailSender(); new Thread(new Runnable() { @Override public void run() { sms.sendTextMail; } }).start(); } @NonNull private static MailInfo creatMail(String toAdd) { final MailInfo mailInfo = new MailInfo(); mailInfo.setMailServerHost; mailInfo.setMailServerPort; mailInfo.setValidate; mailInfo.setUserName; // 你的邮箱地址 mailInfo.setPassword;// 您的邮箱密码 mailInfo.setFromAddress; // 发送的邮箱 mailInfo.setToAddress; // 发到哪个邮件去 mailInfo.setSubject; // 邮件主题 mailInfo.setContent("Android 测试"); // 邮件文本 return mailInfo; }}
