Session session = null; 
ProgressDialog pdialog = null; 
Context context = null; 
EditText reciep, sub, msg; 
String rec, subject, textMessage; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.b9); 

    context = this; 

    Button login = (Button) findViewById(R.id.btn_submit); 
    reciep = (EditText) findViewById(R.id.et_to); 
    sub = (EditText) findViewById(R.id.et_sub); 
    msg = (EditText) findViewById(R.id.et_text); 

    login.setOnClickListener(this); 
} 

@Override 
public void onClick(View v) { 
    rec = reciep.getText().toString(); 
    subject = sub.getText().toString(); 
    textMessage = msg.getText().toString(); 
    Properties props = new Properties(); 
    props.put("mail.smtp.host", "smtp.gmail.com"); 
    props.put("mail.smtp.socketFactory.port", "587"); 
    props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory"); 
    props.put("mail.smtp.auth", "true"); 
    props.put("mail.smtp.port", "587"); 

    session = Session.getDefaultInstance(props, new Authenticator() { 
     protected PasswordAuthentication getPasswordAuthentication() { 
      return new PasswordAuthentication("xyz@gmail.com", "xyz123"); 
     } 
    }); 

    pdialog = ProgressDialog.show(context, "", "Sending Mail...", true);

class RetrieveFeedTask extends AsyncTask<String, Void, String> { 

    @Override 
    protected String doInBackground(String... params) { 

     try{ 
      Message message = new MimeMessage(session); 
      message.setFrom(new InternetAddress("xyz@gmail.com")); 
      message.setRecipients(Message.RecipientType.TO, InternetAddress. 
        parse(rec)); 
      message.setSubject(subject); 
      message.setContent(textMessage, "text/html; charset=utf-8"); 
      Transport.send(message); 
     } catch(MessagingException e) { 
      e.printStackTrace(); 
     } catch(Exception e) { 
      e.printStackTrace();
