Invia email programmaticamente su Android

Question

Quindi sto cercando di inviare un'e-mail in Android senza utilizzare Intent perché ho bisogno che venga inviata in background. Sto seguendo ,

Ho aggiunto .jars come parte del percorso di generazione.

E ho questo codice come la classe

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 ….. 
} 

E ho questo codice come il mio metodo sendEmail che si attiva facendo clic su un pulsante nel menu.

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); 
    } 
} 

Ed ecco la LogCat ho ottenuto da esso

È necessario l'autorizzazione android.permission.INTERNET nel proprio manifest per consentire all'applicazione di aprire un socket di rete.

Answer 4

Hai perso l'autorizzazione INTERNET nel tuo file AndroidManifest.xml?
