Connessione XMPP con Smack 4.1 su Android Studio

Question

Sto provando a eseguire una connessione XMPP con Smack 4.1.0 rc1 da https://github.com/igniterealtime/Smack ho seguito questa guida https://github.com/igniterealtime/Smack/wiki/Smack-4.1-Readme-and-Upgrade-Guide importando il Gradle. Codice

Chiunque potrebbe aiutarmi con questo problema, per favore? Sto solo cercando di verificare se la connessione funziona ..

Answer 1

Sostituire smack-java7 con smack-android nel vostro build.gradle. Questo è documentato in Smack's README.

Answer 2

Prova a connettere il server con la classe XMPPConnection.

come collegare:

XMPPConnection con = new XMPPTCPConnection("igniterealtime.org"); 
con.connect(); 

Answer 3

Questo è un aggiornamento della mia ultima applicazione del server di connessione XMPP FCM. Ora, questo progetto utilizza l'ultima versione in questo momento della libreria Smack (4.1.8). Penso che la libreria per Android sia praticamente la stessa per il server java.

https://github.com/carlosCharz/fcmxmppserverv2

Questo è il mio progetto Java di esempio per mostrare la Firebase Nuvola Messaging (FCM) Server XMPP Connection. Questo server invia i dati a un'app client tramite il server CCS CCM utilizzando il protocollo XMPP.

https://github.com/carlosCharz/fcmxmppserver

e anche io ho creato un video in youtube in cui spiego che cosa i cambiamenti sono.

Spero vi sia utile.

Ecco un frammento di codice per l'attuazione:

public class CcsClient implements StanzaListener { 

    //Other code 

    public void connect() throws XMPPException, SmackException, IOException { 
    XMPPTCPConnection.setUseStreamManagementResumptionDefault(true); 
    XMPPTCPConnection.setUseStreamManagementDefault(true); 

    XMPPTCPConnectionConfiguration.Builder config = XMPPTCPConnectionConfiguration.builder(); 
    config.setServiceName("FCM XMPP Client Connection Server"); 
    config.setHost(Util.FCM_SERVER); 
    config.setPort(Util.FCM_PORT); 
    config.setSecurityMode(SecurityMode.ifpossible); 
    config.setSendPresence(false); 
    config.setSocketFactory(SSLSocketFactory.getDefault()); 
    // Launch a window with info about packets sent and received 
    config.setDebuggerEnabled(mDebuggable); 

    // Create the connection 
    connection = new XMPPTCPConnection(config.build()); 

    // Connect 
    connection.connect(); 

    // Enable automatic reconnection 
    ReconnectionManager.getInstanceFor(connection).enableAutomaticReconnection(); 

    // Handle reconnection and connection errors 
    connection.addConnectionListener(new ConnectionListener() { 

     @Override 
     public void reconnectionSuccessful() { 
      logger.log(Level.INFO, "Reconnection successful ..."); 
      // TODO: handle the reconnecting successful 
     } 

     @Override 
     public void reconnectionFailed(Exception e) { 
      logger.log(Level.INFO, "Reconnection failed: ", e.getMessage()); 
      // TODO: handle the reconnection failed 
     } 

     @Override 
     public void reconnectingIn(int seconds) { 
      logger.log(Level.INFO, "Reconnecting in %d secs", seconds); 
      // TODO: handle the reconnecting in 
     } 

     @Override 
     public void connectionClosedOnError(Exception e) { 
      logger.log(Level.INFO, "Connection closed on error"); 
      // TODO: handle the connection closed on error 
     } 

     @Override 
     public void connectionClosed() { 
      logger.log(Level.INFO, "Connection closed"); 
      // TODO: handle the connection closed 
     } 

     @Override 
     public void authenticated(XMPPConnection arg0, boolean arg1) { 
      logger.log(Level.INFO, "User authenticated"); 
      // TODO: handle the authentication 
     } 

     @Override 
     public void connected(XMPPConnection arg0) { 
      logger.log(Level.INFO, "Connection established"); 
      // TODO: handle the connection 
     } 
    }); 

    // Handle incoming packets (the class implements the StanzaListener) 
    connection.addAsyncStanzaListener(this, 
      stanza -> stanza.hasExtension(Util.FCM_ELEMENT_NAME, Util.FCM_NAMESPACE)); 

    // Log all outgoing packets 
    connection.addPacketInterceptor(stanza -> logger.log(Level.INFO, "Sent: {}", stanza.toXML()), stanza -> true); 

    connection.login(fcmServerUsername, mApiKey); 
    logger.log(Level.INFO, "Logged in: " + fcmServerUsername); 
}\ 

}
