Не удается отправить почту с помощью JavaMail API
У меня есть следующий код, который пытается отправить письмо в фоновом режиме. Я использовал текстовое представление, чтобы увидеть исключение. Однако, хотя в текстовом окне ничего не отображается, я также не могу получить письмо. Поэтому я не уверен, была ли почта доставлена успешно или нет. Кто-нибудь может мне помочь?
Основываясь на предложениях, я изменил свою программу следующим образом:
новый Sender.java
public class Sender extends Activity {
Button Send;
TextView text;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_sender);
Send = (Button) findViewById(R.id.mail);
text = (TextView) findViewById(R.id.textView1);
StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder()
.permitAll().build();
StrictMode.setThreadPolicy(policy);
Send.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
new SendMail().execute();
}
});
}
private class SendMail extends AsyncTask<String, Void, String>
{

Integer result;
@Override

// TODO Auto-generated method stub
super.onPreExecute();
pd = new ProgressDialog(Sender.this);
pd.setTitle("Uploading");
pd.setMessage("Uploading logs. Please wait");
pd.setCancelable(false);
pd.show();
}
@Override
protected String doInBackground(String... params) {
// TODO Auto-generated method stub
MailSender sender = new MailSender("[email protected]", "password");
String[] toAddress = {"[email protected]"};
sender.setTo(toAddress);
sender.setFrom("[email protected]");
sender.setSubject("Test mail");
sender.setBody("This is the mail body");
try {
if(sender.send()) {
System.out.println("Message sent");
result = 1;
} else {
result = 2;
}
} catch (Exception e) {
error = e.getMessage();
Log.e("SendMail", e.getMessage(), e);
}
result = 3;
return null;
}
protected void onPostExecute() {
pd.dismiss();
if(error!=null) {
text.setText(error);
}
if(result==1) {

После изменения программы, когда я нажимаю кнопку, она останавливается в состоянии перед выполнением, отображая «Загрузка журналов». Пожалуйста, подождите & quot ;. Почта не может быть отправлена.
