问题描述
电子邮件发送成功，但问题是附加文件的电子邮件，我怎么发email.I现在用以下code。
公共类的SendMail扩展javax.mail.Authenticator {
私人字符串_user;
私人字符串_pass;
私有String [_to]
私人字符串_from;
私人字符串_port;
私人字符串_sport;
私人字符串_host;
私人字符串_subject;
私人字符串_body;
私人布尔_auth;
私人布尔_debuggable;
私人多部分_multipart;
公众的SendMail（）{
_host =smtp.gmail.com; //默认SMTP服务器
_port =465; //默认的SMTP端口
_sport =465; //默认的SocketFactory端口
_user =; //用户名
_pass =; // 密码
_from =; //电子邮件，发送
_subject =; // 电子邮件主题
_body =; //邮件正文
_debuggable = FALSE;打开或关闭//调试模式 - 默认关闭
_auth = TRUE; // SMTP认证 - 拖欠
_multipart =新MimeMultipart的（）;
//也有一些是错误的MAILCAP，JavaMail的找不到的处理程序/混合组成部分，所以这一点需要添加。
支持MailcapCommandMap MC =（支持MailcapCommandMap）CommandMap.getDefaultCommandMap（）;
mc.addMailcap（text / html的;;的X Java的内容处理器= com.sun.mail.handlers.text_html）;
mc.addMailcap（文/ XML ;;的X Java的内容处理器= com.sun.mail.handlers.text_xml）;
mc.addMailcap（text / plain的;;的X Java的内容处理器= com.sun.mail.handlers.text_plain）;

mc.addMailcap（信息/ RFC822 ;;的X Java的内容处理器= com.sun.mail.handlers.message_rfc822）;
CommandMap.setDefaultCommandMap（MC）;
}
公众的SendMail（用户字符串，字符串通）{
本（）;
_user =用户;
_pass =通;
}
公共布尔的send（）抛出异常{
属性道具= _setProperties（）;
如果（_user.equals（）及＆安培;！_pass.equals（！）及＆安培; _to.length大于0＆安培;＆安培;！_from.equals（）及＆安培;！_subject .equals（）及＆安培;！_body.equals（））{
会话会话= Session.getInstance（道具，这一点）;

名单＆LT;字符串＆GT; addressTo =新的ArrayList＆LT;字符串＆GT;（）;
对于（字符串地址：_to）{
如果（地址== NULL || addr.trim（）。等于（））
继续;
addressTo.add（地址）;
}
网际[] actAddressTo =新的网际[addressTo.size（）];
INT I = 0;
对于（字符串地址：addressTo）{
actAddressTo [我] =新的网际（地址）;
我++;
}
msg.setRecipients（MimeMessage.RecipientType.TO，actAddressTo）;
msg.setSubject（_subject）;
msg.setSentDate（新日期（））;
//设置邮件正文
// BodyPart的messageBodyPart =新MimeBodyPart（）;
//messageBodyPart.setText(_body）;
//_multipart.addBodyPart(messageBodyPart）;
//msg.setContent(_multipart，text / html的）;
msg.setContent（_body，text / html的）;
// 发电子邮件
Transport.send（MSG）;
返回true;
} 其他 {
返回false;
}
}
公共无效addAttachment（字符串文件名）抛出异常{
BodyPart的messageBodyPart =新MimeBodyPart（）;
数据源源=新FileDataSource（文件名）;
messageBodyPart.setDataHandler（新的DataHandler（源））;
messageBodyPart.setFileName（文件名）;
_multipart.addBodyPart（messageBodyPart）;
}
@覆盖
公共Password验证的getPasswordAuthentication（）{
返回新的PasswordAuthentication（_user，_pass）;
}
私人性质_setProperties（）{
属性道具=新特性（）;
props.put（mail.smtp.host，_host）;
如果（_debuggable）{
props.put（mail.debug，真）;
}
如果（_auth）{

}

// getter和setter
公共字符串getBody（）{
返回_body;
}
公共无效setBody（字符串_body）{

}
请帮帮我吗？
解决方案
的String []的mailto = {};
开放的我们的uri = Uri.fromFile（新文件（Environment.getExternalStorageDirectory（）getAbsolutePath（）+/ CALC /报告/，pdfname）。）;
意图emailIntent =新的意图（Intent.ACTION_SEND）;
emailIntent.putExtra（Intent.EXTRA_EMAIL，邮寄地址）;
emailIntent.putExtra（Intent.EXTRA_SUBJECT，计算PDF报告）;
emailIntent.putExtra（Intent.EXTRA_TEXT，ViewAllAccountFragment.selectac +PDF报告）;
emailIntent.setType（应用程序/ PDF格式）;
emailIntent.putExtra（Intent.EXTRA_STREAM，URI）;
startActivity（Intent.createChooser（emailIntent，使用电子邮件））;
The email is sent successfully,but problem is attaching file with email,how i send an email.I am using below code.

// There is something wrong with MailCap, javamail can not find a handler for the multipart/mixed part, so this bit needs to be added.

Please help me?
解决方案
String[] mailto = {""};
Uri uri = Uri.fromFile(new File(Environment.getExternalStorageDirectory().getAbsolutePath() + "/CALC/REPORTS/",pdfname ));
Intent emailIntent = new Intent(Intent.ACTION_SEND);
emailIntent.putExtra(Intent.EXTRA_EMAIL, mailto);
emailIntent.putExtra(Intent.EXTRA_SUBJECT, "Calc PDF Report");
emailIntent.putExtra(Intent.EXTRA_TEXT, ViewAllAccountFragment.selectac+" PDF Report");
emailIntent.setType("application/pdf");
emailIntent.putExtra(Intent.EXTRA_STREAM, uri);
startActivity(Intent.createChooser(emailIntent, "Send email using:"));
