How to store and show the chat history

Hi,

    While leaving the chat room the chat history is deleted how to store and show the chat history 

There's no ability to change conneting url to server(or option value)

Sorry it's for another project

Problem with connecting to NodeJS server

For my NodeJS server code, I'm using the chat server code that is linked to in the socket io android tutorial.

I'm following the tutorial above to a tee in my android project.

build.gradle:

...
dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.3.0'
    compile 'com.android.support:design:23.3.0'
    compile 'com.github.nkzawa:socket.io-client:0.3.0'
}

AndroidManifest.xml:

...
<uses-permission android:name="android.permission.INTERNET" />
...

MainActivity.java:

import com.github.nkzawa.socketio.client.IO;
import com.github.nkzawa.socketio.client.Socket;

public class MainActivity extends AppCompatActivity {

    private Socket mSocket;
    {
        try {
            mSocket = IO.socket("http://chatserver:3000");
            Log.e("CONNECTED", "SUCCESS");
        } catch (URISyntaxException e) {
            Log.e("ERROR", "ERROR CONNECTING");
        }
    }
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        mSocket.connect();
        mSocket.emit("message", "message");
    }
}

When I compile this, no matter what I put as the URL for IO.socket(<url>), it always logs out that it connected. When I load the app, it's supposed to emit message and send "message", but I never get it on the server. I never even get a "user connected" log in my server log, which I have setup to log out anytime a something connects to it.

Just to test to make sure my server code isn't faulty, I created a client project in NodeJS:

client.js:

var io = require('socket.io-client'),
socket = io.connect('http://localhost:3000');

socket.on('connect', function(){
  console.log("connected")
});

And it and the server both log out 'connected' when I run it. So something is wrong with the java code.... I can't figure it out.

Timout Issue

I downloaded you source code and changed the CHAT_SERVER_URL to my localhost nodejs socket io instance and its always throwing error Connect_error. I tried with connecting to my localhost server using the plain html for testing purpose and it worked without any issues. Could you please check where I'm doing wrong?

Hi nkzawa,
May I know if this lib support namespace ?
Need to integration with nodejs server, Automattic/socket.io.
Thanks.

Please help me ..please fix this

Custom socket id from android side

In the android library, socket.id() returns the id of the socket, however, there is no method (that I found in the jar file) that lets us set the socket id.

How can I set the socket id for my communication. In the nodejs sample, setting socket.id = "customName" works allowing us to decide our own name space for the sockets. Is there such an implementation in android?

I am developing a chat app wherein I want the socket.id() of the users to be their username itself. So irrespective of when they connect, instead of getting a random id, it is fixed to their username. I plan to set the id as soon as a connection is made.

In Nodejs my code is following -

io.on('connection', (socket)=>{
  console.log('new connection received');
  console.log(socket.id)
  socket.id = "username"
  console.log(socket.id)

  //other methods
}

This changes the socket id, but io.to(id).emit('new_message', data) does not work. If i use the random id generated, then this method is working just fine.

Please advise.

Cannot connect to the scoket io server

This is my server

var app = require('http').createServer()
var io = require('socket.io')(app);
var fs = require('fs');

var init = function(port){
    app.listen(port);
}

io.on('connection', function(socket){
    console.log('connected');
    socket.on('room_request', function(msg){
        console.log(msg);
        //room_index = msg;

        for( i = 0; i < msg.length; i++)
        {   
            socket.join(msg[i]);
            console.log('channel created');
        }
        socket.on('disconnect', function(){
            for( i = 0; i < msg.length; i++)
            {   
                console.log('user disconnected');
                socket.leave(msg[i]);
                console.log('room closed');
            }
        });
    });
});



var sendMessage = function(tId,message){
    io.to(tId).emit('ping',message);
}

exports.sendMessage = sendMessage;
exports.init = init;

The init is called from another file.
The server works because I tried connecting to it from a simple html javascript app.

I downloaded the app and replaced the http://chat.socket.io with 'localhost:8089'(Thats the port on which the server is running).
I ran it on the simulator so the localhost would resolve to the same machine. But still the server is not hit.
Anything wrong that I am doing anywhere?

Socket Disconnect if (android) app is in background and multiple app opens

Hi,

We developed a chat application for android using socket.io library, But we are facing one issue.

When we kept app in background socket remains connected, even if we keep it idle for some time, socket doesn't disconnect which is fine, but the problem comes when we open any other app, socket disconnects.

Can you please tell us what can be the problem & solution for that.

Thanks in advance...

is there a java server sample that can work with this project?

Hi,
since I cannot join the chat.socket.io , I tried to use a simple java server sample to run this project. But it show these log when I emit login event:

2016-12-12 10:31:47.386 ERROR 582 --- [ntLoopGroup-3-4] c.c.socketio.JsonSupportWrapper : Can't read value: ["chatevent","{userName:gg}"] for type: class com.corundumstudio.socketio.protocol.Event

And I check the json android client submit , find out the source code wrapped everything with jsonarray as above and it cannot be mapped to a com.corundumstudio.socketio.protocol.Event class. Please help, how can I make it run?

External messages to left

Hi, I would show external messages from the outside on the left side of the screen and messages sent by the myself on the right side of the screen. I've created two different item_message for the right side and for the left side, but I don't know how to implement this. Could you help me with a code snippet?
Thank you in advance.

Authentication with socketio-jwt - send query along with connection

Hi,
I read this interesting article about token based authorisation : https://auth0.com/blog/2014/01/15/auth-with-socket-io/

Does this library have the ability to send a query on connection?

Like show in this part of the code:

var socket = io.connect('', {
    query: 'token=' + token
});

after my android socket.io reconnect ，can not send message，why?

When my network is broken ,and then connect . My socket.io will reconnect automatic，but then I cant send message？
