first make sure you are not using the native smack jar you need the ported or the patched one (asmack) to because native smack wont work n android

then try these configurations

   SmackConfiguration.setPacketReplyTimeout(15000);
   ConnectionConfiguration connectionConfig = new ConnectionConfiguration(host, port);
   connectionConfig.setRosterLoadedAtLogin(true);
   connectionConfig.setSendPresence(true);
   connectionConfig.setSASLAuthenticationEnabled(false);
   connectionConfig.setReconnectionAllowed(true);
   connection = new XMPPConnection(connectionConfig);
