在Android中以编程方式发送电子邮件

所以我想在Android中发送电子邮件,而不使用意图,因为我需要它在后台发送。 我正在关注这个post ,

我有作为构buildpath的一部分添加的.jars。

我有这个代码作为类

package cistoran.partyPlanner; import java.util.Date; import java.util.Properties; import javax.activation.CommandMap; import javax.activation.DataHandler; import javax.activation.DataSource; import javax.activation.FileDataSource; import javax.activation.MailcapCommandMap; import javax.mail.BodyPart; import javax.mail.Multipart; import javax.mail.PasswordAuthentication; import javax.mail.Session; 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 class Mail extends javax.mail.Authenticator { private String _user; private String _pass; private String[] _to; private String _from; private String _port; private String _sport; private String _host; private String _subject; private String _body; private boolean _auth; private boolean _debuggable; private Multipart _multipart; public Mail() { _host = "smtp.gmail.com"; // default smtp server _port = "465"; // default smtp port _sport = "465"; // default socketfactory port _user = ""; // username _pass = ""; // password _from = ""; // email sent from _subject = ""; // email subject _body = ""; // email body _debuggable = false; // debug mode on or off - default off _auth = true; // smtp authentication - default on _multipart = new MimeMultipart(); // There is something wrong with MailCap, javamail can not find a handler for the multipart/mixed part, so this bit needs to be added. MailcapCommandMap mc = (MailcapCommandMap) CommandMap.getDefaultCommandMap(); mc.addMailcap("text/html;; x-java-content-handler=com.sun.mail.handlers.text_html"); mc.addMailcap("text/xml;; x-java-content-handler=com.sun.mail.handlers.text_xml"); mc.addMailcap("text/plain;; x-java-content-handler=com.sun.mail.handlers.text_plain"); mc.addMailcap("multipart/*;; x-java-content-handler=com.sun.mail.handlers.multipart_mixed"); mc.addMailcap("message/rfc822;; x-java-content-handler=com.sun.mail.handlers.message_rfc822"); CommandMap.setDefaultCommandMap(mc); } public Mail(String user, String pass) { this(); _user = user; _pass = pass; } public boolean send() throws Exception { Properties props = _setProperties(); if(!_user.equals("") && !_pass.equals("") && _to.length > 0 && !_from.equals("") && !_subject.equals("") && !_body.equals("")) { Session session = Session.getInstance(props, this); MimeMessage msg = new MimeMessage(session); msg.setFrom(new InternetAddress(_from)); InternetAddress[] addressTo = new InternetAddress[_to.length]; for (int i = 0; i < _to.length; i++) { addressTo[i] = new InternetAddress(_to[i]); } msg.setRecipients(MimeMessage.RecipientType.TO, addressTo); msg.setSubject(_subject); msg.setSentDate(new Date()); // setup message body BodyPart messageBodyPart = new MimeBodyPart(); messageBodyPart.setText(_body); _multipart.addBodyPart(messageBodyPart); // Put parts in message msg.setContent(_multipart); // send email Transport.send(msg); return true; } else { return false; } } public void addAttachment(String filename) throws Exception { BodyPart messageBodyPart = new MimeBodyPart(); DataSource source = new FileDataSource(filename); messageBodyPart.setDataHandler(new DataHandler(source)); messageBodyPart.setFileName(filename); _multipart.addBodyPart(messageBodyPart); } @Override public PasswordAuthentication getPasswordAuthentication() { return new PasswordAuthentication(_user, _pass); } private Properties _setProperties() { Properties props = new Properties(); props.put("mail.smtp.host", _host); if(_debuggable) { props.put("mail.debug", "true"); } if(_auth) { props.put("mail.smtp.auth", "true"); } props.put("mail.smtp.port", _port); props.put("mail.smtp.socketFactory.port", _sport); props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory"); props.put("mail.smtp.socketFactory.fallback", "false"); return props; } // the getters and setters public String getBody() { return _body; } public void setBody(String _body) { this._body = _body; } public void setTo(String[] toArr) { this._to = toArr; } public void setFrom(String string) { this._from = string; } public void setSubject(String string) { this._subject = string; } // more of the getters and setters ….. } 

我有这个代码作为我的sendEmail方法,通过点击菜单中的一个button来激活。

 public void sendEmail() { EditText childNameBox = (EditText) findViewById(R.id.childNameBox); EditText parentNameBox = (EditText) findViewById(R.id.parentNameBox); EditText phoneNumberBox = (EditText) findViewById(R.id.phoneNumberBox); EditText ageBox = (EditText) findViewById(R.id.ageBox); EditText notesBox = (EditText) findViewById(R.id.notesBox); EditText colorsBox = (EditText) findViewById(R.id.colorsBox); EditText dateBox = (EditText) findViewById(R.id.dateBox); EditText timeBox = (EditText) findViewById(R.id.timeBox); childName = childNameBox.toString(); parentName = parentNameBox.toString(); childAge = ageBox.toString(); phoneNumber = phoneNumberBox.toString(); colorChoice = colorsBox.toString(); notesText = notesBox.toString(); dateDay = dateBox.toString(); timeDay = timeBox.toString(); emailCombined = childName + bN + parentName + bN + childAge + bN + phoneNumber + bN + colorChoice + bN + notesText + bN + dateDay + bN + timeDay; Mail m = new Mail("emailaddress", "password"); String[] toArr = {"cistoran@live.com", "ivan017@gmail.com"}; m.setTo(toArr); m.setFrom("ivan017@gmail.com"); m.setSubject("Party Booked"); m.setBody(emailCombined); try { //m.addAttachment("/sdcard/filelocation"); if(m.send()) { Toast.makeText(PartyPlannerActivity.this, "Sent Email.", Toast.LENGTH_LONG).show(); } else { Toast.makeText(PartyPlannerActivity.this, "Email was not sent.", Toast.LENGTH_LONG).show(); } } catch(Exception e) { //Toast.makeText(MailApp.this, "There was a problem sending the email.", Toast.LENGTH_LONG).show(); Log.e("PartyPlannerActivity", "Could not send email.", e); } } 

这里是我从中得到的LogCat

INTERNET权限添加到您的清单。

你在你的AndroidManifest.xml文件中错过了INTERNET权限吗?

您可能需要将INTERNET权限添加到您的应用程序。

您需要清单中的android.permission.INTERNET权限才能使应用程序打开networking套接字。

将此代码插入清单文件中:

 <uses-permission android:name="android.permission.INTERNET"/>
