android studio邮件开发记录

1.代码

MyAuthenticator.java

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);
    }
}

MailService.java

/*
 * Copyright (c)2016 thatluck
 * 版权所有，违者必究
 */




import java.io.IOException;

import java.io.InputStream;
import java.util.Date;
import java.util.Properties;

import javax.mail.Message;
import javax.mail.MessagingException;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;

public class MailService {

    public static void send_email(String content) throws IOException, MessagingException{

        Properties properties = new Properties();
        String to = "收信地址";
        String subject ="提交日志";

       

        properties.put("mail.smtp.host", "smtp.qq.com");
        properties.put("mail.smtp.port", "465");
        properties.setProperty("mail.debug", "true");
        properties.setProperty("mail.smtp.auth", "true");  
          
        // 协议名称设置为smtps，会使用SSL  
        properties.setProperty("mail.transport.protocol", "smtps"); 
        properties.put("mail.smtp.ssl.enable", "true"); 

        properties.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
        properties.put("mail.smtp.socketFactory.fallback", "false");
        properties.put("mail.smtp.socketFactory.port", properties.get("mail.smtp.port").toString());
        MyAuthenticator authenticator = new MyAuthenticator("发送地址", "授权码");
        javax.mail.Session sendMailSession = javax.mail.Session.getDefaultInstance(properties, authenticator);
        MimeMessage mailMessage = new MimeMessage(sendMailSession);
        mailMessage.setFrom(new InternetAddress("发送地址"));
       
        mailMessage.setRecipient(Message.RecipientType.TO, new InternetAddress(to));
        mailMessage.setSubject(subject, "UTF-8");
        mailMessage.setSentDate(new Date());
        mailMessage.setText(content);
        Transport.send(mailMessage);
    }
}

build.gradle文件中配置dependenies信息如下：

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    compile 'com.sun.mail:android-mail:1.5.5'
    compile 'com.sun.mail:android-activation:1.5.5'
}

2.混淆签名打包

......

Warning:Ignoring InnerClasses attribute for an anonymous inner class
(javax.activation.DataHandler$1) that doesn't come with an
associated EnclosingMethod attribute. This class was probably produced by a
compiler that did not target the modern .class file format. The recommended
solution is to recompile the class from source, using an up-to-date compiler
and without specifying any "-target" type options. The consequence of ignoring
this warning is that reflective operations on this class will incorrectly
indicate that it is *not* an inner class.

解决方案：

升级androidstudio到最新版本2.1.2

Build时使用InstantRun功能构建程序

然后会出现下面的新的问题：

解决方案：

在proguardFile中添加如下设置

-keep class org.apache.** { *; }
-keep class com.sun.** { *; }
-dontwarn com.sun.mail.handlers.handler_base

注意：

AndroidStudio版本号：2.1.2

设置InstanceRun模式调试程序

InstanceRun的介绍可以参考：

1.Instant Run

2.Android Studio2.0的逆天功能Instant Run
