在我的应用程序中，我想发送一封电子邮件。邮件的发送方式可以知道吗？

我正在使用AsyncTask，但是如何识别邮件是否已发送，以便我可以在postExecute方法中停止进度条。请任何帮助。这是我的代码。它可以正常发送电子邮件...

public class SendMainActivity extends Activity { 
Button send = null; 
EditText mailid = null; 
String emailId = null; 
ConnectivityManager conMan = null; 
NetworkInfo Info = null; 
ProgressBar pro = null; 
@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.main); 
    send = (Button)findViewById(R.id.button1); 
    mailid = (EditText)findViewById(R.id.editText1); 
    pro = (ProgressBar)findViewById(R.id.progressBar1); 
    send.setOnClickListener(new OnClickListener() { 
     @Override 
     public void onClick(View arg0) { 
      conMan = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE); 
      Info = conMan.getActiveNetworkInfo(); 
      emailId = mailid.getText().toString(); 
      if(Info == null){ 
       Toast.makeText(getApplicationContext(), "no net connection ", Toast.LENGTH_LONG).show(); 
      }else{ 
       new SendEmail().execute(); 
      } 
     } 
    }); 
} 
class SendEmail extends AsyncTask<Void, Void, Integer>{ 
     @Override 
     protected void onPreExecute() 
     { 
      pro.setVisibility(View.VISIBLE); 
      pro.setProgress(0); 
     } 
    @Override 
    protected Integer doInBackground(Void... params) { 
     // TODO Auto-generated method stub 
     try { 
      GmailSender sender = new GmailSender("[email protected]", "userpass"); 
      sender.sendMail("This is Subject", 
        "This is Body how r u ..", 
        "[email protected]", 
        emailId); 
     } catch (Exception e) { 
      Log.e("SendMail", e.getMessage(), e); 
     } 
     return null; 
    } 
    @Override 
    protected void onPostExecute(Integer result) { 
     // TODO Auto-generated method stub 
     super.onPostExecute(result); 
     pro.destroyDrawingCache(); 
    } 
    } 
}
