I am trying to run the socketcluster-android-client demo app (https://github.com/sacOO7/socketcluster-android-demo). I have the server running at localhost:8000 successfully. I'm connecting to: ws://localhost:8000/socketcluster/ from my mobile.
When I try to run the app, the connection fails with the error:
Got connect error com.neovisionaries.ws.client.WebSocketException: Failed to connect to 'localhost:8000': failed to connect to localhost/127.0.0.1 (port 8000) from /127.0.0.1 (port 42405) after 5000ms: isConnected failed: ECONNREFUSED (Connection refused)
I've verified the following(from other SO answers):
- firewall access
- successful telnet to localhost:8000
- PC on which the sever in running and my mobile are on the same wifi network
- upgrade to latest node version
Here's the code that tries to connect to the socket:
socket = new Socket(url);
socket.setListener(new BasicListener() {
public void onConnected(Socket socket, Map<String, List<String>> headers) {
socket.createChannel("MyClassroom").subscribe(new Ack() {
@Override
public void call(String name, Object error, Object data) {
if (error==null){
Log.i ("Success","subscribed to channel "+name);
}
}
});
Log.i("Success ","Connected to endpoint");
}
public void onDisconnected(Socket socket, WebSocketFrame serverCloseFrame, WebSocketFrame clientCloseFrame, boolean closedByServer) {
Log.i("Success ","Disconnected from end-point");
}
public void onConnectError(Socket socket,WebSocketException exception) {
Log.i("Success ","Got connect error "+ exception);
}
public void onSetAuthToken(String token, Socket socket) {
socket.setAuthToken(token);
}
public void onAuthentication(Socket socket,Boolean status) {
if (status) {
Log.i("Success ","socket is authenticated");
} else {
Log.i("Success ","Authentication is required (optional)");
}
}
});
socket.setReconnection(new ReconnectStrategy().setMaxAttempts(10).setDelay(3000));
socket.connectAsync();
