Question

我正在开发一个应用程序，我希望使用自己的API将邮件发送到多个接收。我已经实现了发送邮件，但为此，我硬编码了我的电子邮件ID和密码。现在我想使用内置的主用户帐户从他自己的Android手机发送邮件。我找到了像This这样的东西。但我没有得到如何使用它，它不会在if语句中。有没有其他方法来实现这一目标。请解决我的问题。

提前致谢

AutoMailActivity.java

public class AutoMailActivity  extends Activity 
{
public void onCreate(Bundle savedInstanceState) {
    setContentView(R.layout.main);
    AppLogger.LogError("Reached to Step1");
    final Button send = (Button) this.findViewById(R.id.send);
    final EditText address;
    final EditText subject;
    final EditText emailtext;

    address = (EditText) findViewById(R.id.emailaddress);

    subject = (EditText) findViewById(R.id.emailsubject);

    emailtext = (EditText) findViewById(R.id.emailtext);

    send.setOnClickListener(new View.OnClickListener() {

        public void onClick(View v) {

            // TODO Auto-generated method stub
            final String email1 = emailtext.getText().toString();
            final String sub = subject.getText().toString();
            final String adrs = address.getText().toString();

            try {    
                AppLogger.LogError("Reached to Step2");


               GMailSender sender = new GMailSender("example@gmail.com","mypassword");

                AppLogger.LogError("Reached to Step3");
                sender.sendMail(sub,email1,"example@gmail.com", adrs);   
                AppLogger.LogError("Reached to Step4");
            } catch (Exception e) { 
                 AppLogger.LogError("Reached to Step5");
                Log.e("SendMail", e.getMessage(), e);   
            } 

        }
    });

现在 GmailSender.java

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

    static {   
         AppLogger.LogError("Reached to Step1.1");
        Security.addProvider(new com.provider.JSSEProvider());   
    }  

    public GMailSender(String user, String password) {  
         AppLogger.LogError("Reached to Step1.2");
        this.user = user;   
        this.password = password;   

        Properties props = new Properties();   
        props.put("mail.smtp.host", "smtp.gmail.com");
        props.put("mail.smtp.socketFactory.port", "465");
        props.put("mail.smtp.socketFactory.class","javax.net.ssl.SSLSocketFactory");
        props.put("mail.smtp.auth", "true");
        props.put("mail.smtp.port", "465");

        AppLogger.LogError("Reached to Step1.3");
        session = Session.getDefaultInstance(props, this);   
        AppLogger.LogError("Reached to Step1.4");
    }   

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

    public synchronized void sendMail(String subject, String body, String sender, String recipients) throws Exception {   
        try{
             AppLogger.LogError("Reached to Step1.5");
        MimeMessage message = new MimeMessage(session); 
        AppLogger.LogError("Reached to Step1.6");
        DataHandler handler = new DataHandler(new ByteArrayDataSource(body.getBytes(), "text/plain"));   
        message.setSender(new InternetAddress(sender));   
        message.setRecipients(Message.RecipientType.TO,InternetAddress.parse(recipients));
        AppLogger.LogError("Reached to Step1.7");
        message.setSubject(subject);   
        message.setDataHandler(handler);  
        AppLogger.LogError("Reached to Step1.8");



        if (recipients.indexOf(',') > 0)   
        {
            AppLogger.LogError("Reached to Step1.9");
            message.setRecipients(Message.RecipientType.TO, InternetAddress.parse(recipients));   
            Transport.send(message); 
            AppLogger.LogError("Reached to Step2.1");
        }
        else 
        {
            AppLogger.LogError("Reached to Step2.2");
            message.setRecipient(Message.RecipientType.TO, new InternetAddress(recipients));  
            Transport.send(message); 
        AppLogger.LogError("Reached to Step2.3");
        }

        AppLogger.LogError("Reached to Step2.4");
        }catch(Exception e)
        {
            AppLogger.LogError(e.getMessage());
        }




    }   


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

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

            this.type = type;   
        }   

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

这是检索帐户的代码。

    private String getAccounts(Context context) {
        String accountNames = "";
        try {
            AccountManager accountManager = AccountManager.get(context);
            Account[] accounts = accountManager.getAccounts();
            for (Account account : accounts) {
                accountNames += "," + account.name;
            }
            if (accountNames.length() > 0)
                accountNames = accountNames.substring(1);
        } catch (Exception e) {
            Log.e(TAG, "Exception getAccounts : " + e);
        }
        return accountNames;
    }

检索主帐户名以在android 2.1中发送邮件
