android: не удается создать соединение с openfire

Question

Я пытаюсь создать соединение с открытым огнем в классе ConnectionAsyncTask. Я использую Смак библиотеку v4.13

Далее следует код:

public class ConnectionAsyncTask extends AsyncTask<Void, Void, Void> { 

    public ConnectionAsyncTask() { 

    } 

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

     XMPPTCPConnectionConfiguration.Builder config = XMPPTCPConnectionConfiguration.builder(); 
     config.setServiceName(HOST); 
     config.setHost(HOST); 
     config.setPort(PORT); 
     config.setDebuggerEnabled(true); 

     mConnection = new XMPPTCPConnection(config.build()); 

     try { 
      mConnection.connect(); 
      Log.i("connect", "connected"); 
     } catch (SmackException e) { 
      e.printStackTrace(); 
     } catch (IOException e) { 
      e.printStackTrace(); 
     } catch (XMPPException e) { 
      e.printStackTrace(); 
     } 

     return null; 
    } 
} 

Но приведенный выше код бросает следующее сообщение об ошибке:

Answer 1

Я не знаю, как это мне помогло .. но ,, в том числе следующие строки build.gradle решить мою проблему:

compile "org.igniterealtime.smack:smack-android:4.1.3" 
compile "org.igniterealtime.smack:smack-bosh:4.1.3" 
compile "org.igniterealtime.smack:smack-tcp:4.1.3" 
compile "org.igniterealtime.smack:smack-im:4.1.3" 
compile "org.jxmpp:jxmpp-jid:0.5.0-alpha6" 
compile "org.igniterealtime.smack:smack-extensions:4.1.3" 

Я не знаю причину этого. Если кто-нибудь знает причину, вы можете редактировать и обновлять мой ответ.

Теперь это, как я был в состоянии сделать соединение:

public class MyAsyncTask extends AsyncTask<Void, Void, Void> { 

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

     // Create a connection to the jabber.org server on a specific port. 
     XMPPTCPConnectionConfiguration config = XMPPTCPConnectionConfiguration.builder() 
       .setServiceName("my-ip") 
       .setHost("my-ip") 
       .setSecurityMode(ConnectionConfiguration.SecurityMode.disabled) 
       .setPort(5222) 
       .setDebuggerEnabled(true) 
       .build(); 

     AbstractXMPPConnection conn2 = new XMPPTCPConnection(config); 
     try { 
      conn2.connect(); 
      Log.i("connecting: ", "Connected"); 
     } catch (SmackException | XMPPException | IOException e) { 
      e.printStackTrace(); 
     } 

     return null; 
    } 
} 

Спасибо в любом случае.

Answer 2

У меня была такая же ошибка.

Мои зависимости были:

compile "org.igniterealtime.smack:smack-android:4.1.7" 
compile "org.igniterealtime.smack:smack-tcp:4.1.7" 
compile "org.igniterealtime.smack:smack-im:4.1.7" 
compile "org.igniterealtime.smack:smack-extensions:4.1.7" 

Я думаю, что он должен делать с JavaxResolver увидеть эту thread.

После того, как я добавил следующую зависимость:

compile "org.igniterealtime.smack:smack-bosh:4.1.7" 

ошибка пошла прочь.

Надеюсь, что это поможет!
