我正在尝试与https://github.com/igniterealtime/Smack

有人可以帮我解决这个问题吗？我只是想检查连接是否有效..

在build.gradle中将smack-java7替换为smack-android。这在Smack's README中有记录。
答案 1 :(得分：1)
这是我上一次FCM XMPP连接服务器应用程序的升级。现在，这个项目在Smack库（4.1.8）的这个时候使用了最新版本。我认为android的库对于java服务器来说是相同的。
https://github.com/carlosCharz/fcmxmppserverv2
这是我展示Firebase云消息传递（FCM）XMPP连接服务器的示例Java项目。此服务器使用XMPP协议通过FCM CCS服务器将数据发送到客户端应用程序。
https://github.com/carlosCharz/fcmxmppserver
我还在youtube上创建了一个视频，在那里我解释了这些变化。
https://www.youtube.com/watch?v=KVKEj6PeLTc
希望你觉得它很有用。
以下是实施的代码段：
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);
}
}

尝试将服务器与XMPPConnection类连接。
如何连接：
XMPPConnection con = new XMPPTCPConnection("igniterealtime.org");
con.connect();
