I'm trying to write a JavaScript server running on node.js using Socket.io that communicates with the client which is my android app (java class). Since I need a combination of a JS server and java client that utilizes the Socket.io (or any other efficient websockets) framework, I found the Gottox/socket-io.-java-client implementation that seemed like it might do the job.
Problem: I'm very new to socket programming and working with Github projects. I tried following the simplistic approach mentioned on the project but ran into build errors with Eclipse, specifically relating to Archiving issues with WebSocket.jar and json-org.jar.
Unable to solve this, I tried importing the project into Android Studio when I ran into a whole different bug, which I'm very unfamiliar with.
I just want to make sure I'm working with this project right in the first place. This is what my client class looks like:
package com.example.culami;
import io.socket.IOAcknowledge;
import io.socket.IOCallback;
import io.socket.SocketIO;
import io.socket.SocketIOException;
import org.json.JSONException;
import org.json.JSONObject;
public class AcknowledgeExample implements IOCallback {
private SocketIO socket;
/**
* @param args
*/
/*public static void main(String[] args) {
try {
new AcknowledgeExample();
} catch (Exception e) {
e.printStackTrace();
}
}*/
public AcknowledgeExample() throws Exception
{
socket = new SocketIO();
socket.connect("http://192.168.0.108:3000/", this);
// Sends a string to the server.
socket.send("Hello Server");
// Sends a JSON object to the server.
socket.send(new JSONObject().put("key", "value").put("key2",
"another value"));
// Emits an event to the server.
socket.emit("event", "argument1", "argument2", 13.37);
}
@Override
public void onMessage(JSONObject json, IOAcknowledge ack) {
try {
System.out.println("Server said:" + json.toString(2));
} catch (JSONException e) {
e.printStackTrace();
}
}
@Override
public void onMessage(String data, IOAcknowledge ack) {
System.out.println("Server said: " + data);
}
@Override
public void onError(SocketIOException socketIOException) {
System.out.println("an Error occured");
socketIOException.printStackTrace();
}
@Override
public void onDisconnect() {
System.out.println("Connection terminated.");
}
@Override
public void onConnect() {
System.out.println("Connection established");
}
@Override
public void on(String event, IOAcknowledge ack, Object... args) {
System.out.println("Server triggered event '" + event + "'");
}
}
I imported the socketio.jar and even WebSocket.jar and json-org.jar because it seemed these were needed as well. Any feedback on what I'm doing wrong or how I should incorporate this library in my android project will be highly appreciated since I've already spent countless hours trying to debug the build issue.
Note: I'm using Android L, API 21 and jdk1.7 to run this project.
