所以我搜索了很多，通过我的应用程序发送电子邮件，但没有用户必须登录电子邮件应用程序并自己发送。我想让他在editText中编写它然后只需按一个按钮发送给我。这就是我所做的：邮件的2个类，我调用它的活动，添加3个库和互联网权限。我做错了什么？
以下是我称之为电子邮件流程的地方：
private View.OnClickListener btnMode1Listener = new
View.OnClickListener() {
@Override
public void onClick(View v) {
suggestionText = entre_suggestion.getText().toString();
Log.i("SendMailActivity", "Send Button Clicked.");
String fromEmail = "fromEmail@gmail.com";
String fromPassword = "frompassword";
String toEmails = "toEmail@gmail.com";
List toEmailList = Arrays.asList(toEmails
.split("\\s*,\\s*"));
Log.i("SendMailActivity", "To List: " + toEmailList);
String emailSubject = "Suggestion";
String emailBody = suggestionText;
new SendMailTask(suggestions.this).execute(fromEmail,
fromPassword, toEmailList, emailSubject, emailBody);
}
};
这是第一堂课＆＃34; GMail＆＃34;：
public class GMail {
final String emailPort = "587";// gmail's smtp port
final String smtpAuth = "true";
final String starttls = "true";
final String emailHost = "smtp.gmail.com";
String fromEmail;
String fromPassword;
List toEmailList;
String emailSubject;
String emailBody;
Properties emailProperties;
Session mailSession;
MimeMessage emailMessage;
public GMail() {
}
public GMail(String fromEmail, String fromPassword,
List toEmailList, String emailSubject, String emailBody) {
this.fromEmail = fromEmail;
this.fromPassword = fromPassword;
this.toEmailList = toEmailList;
this.emailSubject = emailSubject;
this.emailBody = emailBody;
emailProperties = System.getProperties();
emailProperties.put("mail.smtp.port", emailPort);
emailProperties.put("mail.smtp.auth", smtpAuth);
emailProperties.put("mail.smtp.starttls.enable", starttls);
Log.i("GMail", "Mail server properties set.");
}
public MimeMessage createEmailMessage() throws AddressException,
MessagingException, UnsupportedEncodingException {
mailSession = Session.getDefaultInstance(emailProperties, null);
emailMessage = new MimeMessage(mailSession);
emailMessage.setFrom(new InternetAddress(fromEmail, fromEmail));
for (Object toEmail : toEmailList) {
Log.i("GMail","toEmail: "+toEmail);
emailMessage.addRecipient(Message.RecipientType.TO,
new InternetAddress((String) toEmail));
}
emailMessage.setSubject(emailSubject);
emailMessage.setContent(emailBody, "text/html");// for a html email
// emailMessage.setText(emailBody);// for a text email
Log.i("GMail", "Email Message created.");
return emailMessage;
}
public void sendEmail() throws AddressException, MessagingException {
Transport transport = mailSession.getTransport("smtp");
transport.connect(emailHost, fromEmail, fromPassword);
Log.i("GMail","allrecipients: "+emailMessage.getAllRecipients());
transport.sendMessage(emailMessage, emailMessage.getAllRecipients());
transport.close();
Log.i("GMail", "Email sent successfully.");
}
}
这是第二课＆＃34; SendMailtask＆＃34;：
public class SendMailTask extends AsyncTask {
private ProgressDialog statusDialog;
private Activity sendMailActivity;
public SendMailTask(Activity activity) {
sendMailActivity = activity;
}
protected void onPreExecute() {
statusDialog = new ProgressDialog(sendMailActivity);
statusDialog.setMessage("Getting ready...");
statusDialog.setIndeterminate(false);
statusDialog.setCancelable(false);
statusDialog.show();
}
@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(), (List) args[2], args[3].toString(),
args[4].toString());
publishProgress("Preparing mail message....");
androidEmail.createEmailMessage();
publishProgress("Sending email....");
androidEmail.sendEmail();
publishProgress("Email Sent.");
Log.i("SendMailTask", "Mail Sent.");
} 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();
}
}
最后，我添加了3个图书馆：
compile files('libs/activation.jar')
compile files('libs/additionnal.jar')
compile files('libs/mail.jar')
所以是的，我经常搜索并且没有找到如何调试它。我尝试了很多不同的方法但它从未发送过电子邮件。我只想清楚，我不想打开邮件应用程序，我希望在用户不必做任何事情的情况下发送电子邮件。

在您的帐户设置中，允许smtp，并允许不安全的应用
