Android - 让 GMailSender 工作有问题吗？

Question

我正在尝试实现 GMailSender进入我的应用程序，但是我没有看到任何结果或任何工作正常的迹象。没有错误消息，也没有电子邮件。这是我的代码，主要引用了我找到的一个示例。我希望在我的应用程序使用之前让它工作。有谁可能知道还需要做些什么才能让它发挥作用？我已经设置了<uses-permission android:name="android.permission.INTERNET" />在我的 AndroidManifest , 以及 GMailSender.java在我的项目中。感谢您的所有回复!这是代码:

public class SendMail extends Activity {  

@Override  
public void onCreate(Bundle icicle) {  
    super.onCreate(icicle);  
    setContentView(R.layout.activity_mail);  
    final Button send = (Button) this.findViewById(R.id.send);  
    final EditText userid = (EditText) this.findViewById(R.id.userid);  
    final EditText password = (EditText) this.findViewById(R.id.password);  
    final EditText from = (EditText) this.findViewById(R.id.from);  
    final EditText to = (EditText) this.findViewById(R.id.to);  
    final EditText subject = (EditText) this.findViewById(R.id.subject);  
    final EditText body = (EditText) this.findViewById(R.id.mailbody);  
    send.setOnClickListener(new View.OnClickListener() {  
        public void onClick(View view) {  
            GMailSender sender = new GMailSender(userid.getText().toString(), password.getText().toString());  
            try {  
                sender.sendMail(subject.getText().toString(),  
                        body.getText().toString(),  
                        from.getText().toString(),  
                        to.getText().toString());  
            } catch (Exception e) {  
                Log.e("SendMail", e.getMessage(), e);  
            }  
        }  
    });  
}  
}

这是我的 GMailSender 类:

public class GMailSender extends javax.mail.Authenticator {   
private String mailhost = "smtp.gmail.com";   
private String user;   
private String password;   
private Session session;   

static {   
    Security.addProvider(new com.example.lyricist.JSSEProvider());   
}  

public GMailSender(String user, String password) {   
    this.user = user;   
    this.password = password;   

    Properties props = new Properties();   
    props.setProperty("mail.transport.protocol", "smtp");   
    props.setProperty("mail.host", mailhost);   
    props.put("mail.smtp.auth", "true");   
    props.put("mail.smtp.port", "465");   
    props.put("mail.smtp.socketFactory.port", "465");   
    props.put("mail.smtp.socketFactory.class",   
            "javax.net.ssl.SSLSocketFactory");   
    props.put("mail.smtp.socketFactory.fallback", "false");   
    props.setProperty("mail.smtp.quitwait", "false");   

    session = Session.getDefaultInstance(props, this);   
}   

protected PasswordAuthentication getPasswordAuthentication() {   
    return new PasswordAuthentication(user, password);   
}   

public synchronized void sendMail(String subject, String body, String sender, String recipients) throws Exception {   
    try{
    MimeMessage message = new MimeMessage(session);   
    DataHandler handler = new DataHandler(new ByteArrayDataSource(body.getBytes(), "text/plain"));   
    message.setSender(new InternetAddress(sender));   
    message.setSubject(subject);   
    message.setDataHandler(handler);   
    if (recipients.indexOf(',') > 0)   
        message.setRecipients(Message.RecipientType.TO, InternetAddress.parse(recipients));   
    else  
        message.setRecipient(Message.RecipientType.TO, new InternetAddress(recipients));   
    Transport.send(message);   
    }catch(Exception e){

    }
}   

public class ByteArrayDataSource implements DataSource {   
    private byte[] data;   
    private String type;   

    public ByteArrayDataSource(byte[] data, String type) {   
        super();   
        this.data = data;   
        this.type = type;   
    }   

    public ByteArrayDataSource(byte[] data) {   
        super();   
        this.data = data;   
    }   

    public void setType(String type) {   
        this.type = type;   
    }   

    public String getContentType() {   
        if (type == null)   
            return "application/octet-stream";   
        else  
            return type;   
    }   

    public InputStream getInputStream() throws IOException {   
        return new ByteArrayInputStream(data);   
    }   

    public String getName() {   
        return "ByteArrayDataSource";   
    }   

    public OutputStream getOutputStream() throws IOException {   
        throw new IOException("Not Supported");   
    }   
}   
}

@webhoodlum 请提供 GMailSender 类的代码。您需要在 asynctack 中执行此任务 (sendMail)。如果您尝试在主线程中进行网络调用，那么它无法正常工作
