android - Android-有关使GMailSender正常工作的问题？

我正在尝试在我的应用程序中实现GMailSender，但是我看不到任何结果或任何迹象表明一切正常。没有错误消息，也没有电子邮件。这是我的代码，大部分是我找到的示例的参考。我希望它能在成型供我的应用程序使用之前工作。有人可能知道要做什么才能使它起作用吗？我已经在我的<uses-permission android:name="android.permission.INTERNET" />中设置了AndroidManifest，并且在我的项目中也使用了GMailSender.java。感谢您的任何答复！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");
    }
}
}

最佳答案

@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，则它无法正常工作
