Android崩溃日志收集

好几年没写博客了，还是大学生的时候记录过很多学习Android时候遇到的问题以及解决方案。转眼3,4年过去了，前段时间看了看自己以前写的博客，发现水准比较低，所以把以前的博客都给删了，这也间接说明自己成长了许多。本人文采不咋样，所以废话不多说，今天给大家带来一个小工具，一般我们做的App上线后都会去收集客户端崩溃的日志，有很多第三方帮我们做了这个工具，从各种维度进行了分析，但这种一般作为开发者不会去看的，运营专员才会去看。开发讲究的就是立马通知我哪里哪里出问题了，马上修改，好了，那我们就借助java发送邮件的功能在Android中集成一个崩溃信息邮件通知功能吧。

一、准备java发送邮件所需要的jar包

二、建立Android项目

这里只简单介绍几个重要的类

1、自己的Application代码片段

@Override
    public void onCreate()
    {
        super.onCreate();
        Thread.setDefaultUncaughtExceptionHandler(new GlobalExceptionHandler(getApplicationContext()));
    }

2、全局异常类

package com.android.exception2email;
import java.io.ByteArrayOutputStream;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.PrintStream;
import java.util.ArrayList;
import java.util.List;
import java.util.Properties;

import org.xml.sax.Attributes;

import android.content.Context;
import android.content.pm.PackageManager.NameNotFoundException;
import android.os.Build;
import android.sax.Element;
import android.sax.ElementListener;
import android.sax.EndTextElementListener;
import android.sax.RootElement;
import android.util.Xml;

3、邮件发送辅助类

package com.android.exception2email;
import java.util.Date;
import java.util.Properties;
import javax.mail.Authenticator;
import javax.mail.Message;
import javax.mail.MessagingException;
import javax.mail.Multipart;
import javax.mail.PasswordAuthentication;

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 abstract class MailUtil
{

    /**

     */
    public static void sendMail(final MailInfo info) throws MessagingException
    {
        Properties props = new Properties();
        props.put("mail.smtp.host",
            info.getSmtpHost());
        props.put("mail.smtp.auth",
            String.valueOf(info.isNeedAuth()));
        Session session = Session.getDefaultInstance(props,
            new Authenticator()
            {
                @Override
                public PasswordAuthentication getPasswordAuthentication()
                {
                    return new PasswordAuthentication(info.getFrom(),
                        info.getPassword());
                }
            });
        MimeMessage msg = new MimeMessage(session);
        msg.setFrom(new InternetAddress(info.getFrom()));
        InternetAddress[] address = new InternetAddress[info.getToList().length];
        for (int i = 0; i < info.getToList().length; i++)
        {
            address[i] = new InternetAddress(info.getToList()[i]);
        }
        msg.setRecipients(Message.RecipientType.TO,

        Multipart mp = new MimeMultipart();
        MimeBodyPart mbpContent = new MimeBodyPart();
        mbpContent.setText(info.getContent());
        mp.addBodyPart(mbpContent);
        msg.setContent(mp);
        msg.setSentDate(current);
        Transport.send(msg,
            address);

    }

    /**
     * 邮件信息
     */
    public static class MailInfo
    {
        private String from;
        private String password;

        private String content;
        private boolean needAuth;
        private String smtpHost;

        public String getFrom()
        {
            return from;
        }

        public void setFrom(String from)
        {
            this.from = from;
        }

        public String getPassword()
        {
            return password;
        }

        public void setPassword(String password)
        {

            return toList;
        }

        public void setToList(String[] toList)
        {
            this.toList = toList;
        }

        public String getSubject()
        {
            return subject;
        }

        public void setSubject(String subject)
        {
            this.subject = subject;
        }

        public String getContent()

        {
            return smtpHost;
        }

        public void setSmtpHost(String smtpHost)
        {
            this.smtpHost = smtpHost;
        }
    }
}

4、邮件发送者和接受者列表(防止同一个账号发送多次邮件被服务器拒绝，这里我们尽量申请多个Email账号)，xml文件可配置，增加灵活性

<?xml version="1.0" encoding="utf-8"?>
<addrs>
    <from-list>
        <item>
            <account>xxx@xxx</account>
            <password>xxx</password>
        </item>
        <item>
            <account>xxx@xxx</account>
            <password>xxx</password>
        </item>
        <item>
            <account>xxx@xxx</account>
            <password>xxx</password>
        </item>
        <item>
            <account>xxx@xxx</account>
            <password>xxx</password>
        </item>
        <item>
            <account>xxx@xxx</account>
            <password>xxx</password>
        </item>
    </from-list>
	<to-list>
	    <item>xxx@xxx</item>
	</to-list>
</addrs>

我们跑起来看看啊

点击崩溃，我的qq邮箱收到邮件了，信息还是比较全面的

总结：

1、引入这些jar包

2、新建emails.xml文件，内容见上下文

3、Application或其他地方加入代码

Thread.setDefaultUncaughtExceptionHandler(new GlobalExceptionHandler(getApplicationContext()));

ps:emails.xml里面发送者账号请改成自己的哦
