Ich erstelle einen Android-Xmpp-Client mit Smack (4.1.7). Bei der Implementierung der automatischen Neuverbindungsfunktion mithilfe von ReconnectionManager finde ich, dass die Bibliothek doppelte Anmeldeanforderungen sendet. Aus diesem Grund wird die zweite Reconnection vom Server mit dem Fehler Client is already logged in
zurückgewiesen. HierSmack: ReconnectionManager sendet doppelte Login-Anfragen beim Wiederverbinden
ist das XML-Dump von Smack:

Manchmal 06-20 15:42:48.894
und 06-20 15:42:49.654
zwei verschiedenen <stream/>
Strophen gesendet werden, die letztlich die Ausnahme verursachen später.
Gibt es einen Grund für ein solches Verhalten? Mein Client-Seite xmpp Code sieht wie folgt aus:
XMPPTCPConnectionConfiguration connConfig = XMPPTCPConnectionConfiguration.builder().setHost(serverAddress)
.setPort(5222).setDebuggerEnabled(true).setSecurityMode(ConnectionConfiguration.SecurityMode.disabled)
.setUsernameAndPassword(loginUser, passwordUser).setServiceName(serverAddress).build();
XMPPTCPConnection.setUseStreamManagementDefault(true);
XMPPTCPConnection.setUseStreamManagementResumptionDefault(true);
connection = new XMPPTCPConnection(connConfig);
connection.setUseStreamManagement(true);
connection.setUseStreamManagementResumption(true);
XMPPConnectionListener connectionListener = new XMPPConnectionListener();
connection.addConnectionListener(connectionListener);
connection.setPacketReplyTimeout(10000);
connection.addStanzaAcknowledgedListener(new StanzaListener() {
@Override
public void processPacket(Stanza packet) throws SmackException.NotConnectedException {
String id = packet.getStanzaId();
if (StringUtils.isNullOrEmpty(id)) {
return;
}
stanzaAcknowledged(id);
}
});
ReconnectionManager reconnectionManager = ReconnectionManager.getInstanceFor(connection);
reconnectionManager.setEnabledPerDefault(true);
reconnectionManager.enableAutomaticReconnection();
jedes Update zu diesem Thema? Ich stehe vor einem ähnlichen Problem. Wenn ich versuche, die Verbindung wieder herzustellen, geschieht die Verbindung und plötzlich gibt es einen Streamfehlerkonflikt, der besagt, dass der Client bereits angemeldet ist. – Newbiee
