>我的项目使用以下代码，但问题是我还想发送我从相机捕获的图像，我也可以将其保存在卡中.....在下面的代码中，我只需单击图像按钮，消息就会发送到我定义的电子邮件ID，但我也想发送我无法做到的图像。

}
3.）发送邮件任务.java
@SuppressWarnings("rawtypes")
public class SendMailTask extends AsyncTask {
private ProgressDialog statusDialog;
private Activity sendMailActivity;

sendMailActivity = activity;
}
protected void onPreExecute() {
statusDialog = new ProgressDialog(sendMailActivity);
statusDialog.setMessage("Getting ready...");
statusDialog.setIndeterminate(false);
statusDialog.setCancelable(false);
statusDialog.show();
}
@SuppressWarnings("unchecked")
@Override
protected Object doInBackground(Object... args) {
try {
Log.i("SendMailTask", "About to instantiate GMail...");
publishProgress("Processing input....");
GMail androidEmail = new GMail(args[0].toString(),
args[1].toString(), args[2].toString(), args[3].toString(),
args[4].toString(), args[5].toString());
publishProgress("Preparing mail message....");
androidEmail.createEmailMessage();
publishProgress("Sending email....");
androidEmail.sendEmail();
publishProgress("Email Sent.");
Log.i("SendMailTask", "Mail Sent.");
// Config.mailSuccess="1";
} catch (Exception e) {
publishProgress(e.getMessage());
Log.e("SendMailTask", e.getMessage(), e);
}
return null;
}
@Override
public void onProgressUpdate(Object... values) {
statusDialog.setMessage(values[0].toString());
}
@Override
public void onPostExecute(Object result) {
statusDialog.dismiss();
}
}
邮件在相机点击时成功发送，但我无法附加图像。
修改了您的 GMail 类，为您的实现进行必要的更改。
public class GMail {
final String emailPort = "587";
final String smtpAuth = "true";
final String starttls = "true";

public GMail() {
}
@SuppressWarnings("rawtypes")

this.fromEmail = fromEmail;
this.fromPassword = fromPassword;
this.toEmailList = toEmailList;
this.emailSubject = emailSubject;

emailProperties = System.getProperties();
emailProperties.put("mail.smtp.port", emailPort);

}
public MimeMessage createEmailMessage() throws AddressException,

我已经使用端口 465 和密码身份验证测试了此代码
