调用发送邮件函数：

public void sendMail() {String smtp = "smtp.qq.com";String username = "@qq.com";String password = "";String from = "@qq.com";String[] to = { "@qq.com" };String subject = "日志";String content = "你好！<br/>本邮件发送自" + android.os.Build.MODEL + "。";String folder = Environment.getExternalStorageDirectory() + File.separator + AppUtil.toPath(this)+ File.separator + "logs" + File.separator; //获取目录路径List<String> files = FileUtil.findFiles(folder); //获取文件夹下所有文件的绝对路径EmailManager email = new EmailManager(smtp, username, password);if(email.sendMail(from, to, null, subject, content, files, 465)) {for(String file : files) {FileUtil.deleteFile(file);}}}
