Hi all,

I am facing a probleme with threads and sockets I cant figure it out, if someone can help me please i would really appreciate.

There are the facts :

I have a service class NetworkService, inside this class I have a Socket attribute. I would like it be at the state of connected for the whole lifecycle of the service.

To connect the socket I do it in a thread, so if the server has to timeout, it would not block my UI thread.

Problem is, into the thread where I connect my socket everything is fine, it is connected and I can talk to my server, once this thread is over and I try to reuse the socket, in another thread, I have the error message Socket is not connected.

Questions are : - Is the socket automatically disconnected at the end of the thread? - Is their anyway we can pass back a value from a called thread to the caller ?

Thanks a lot,

Here is my code

  public class NetworkService extends Service {

        private Socket  mSocket = new Socket();


  private void _connectSocket(String addr, int port) {
        Runnable connect = new connectSocket(this.mSocket, addr, port);
        new Thread(connect).start();

  }

  private void _authentification() {
        Runnable auth = new authentification();
        new Thread(auth).start();
  }


  private INetwork.Stub mBinder = new INetwork.Stub() {

        @Override
        public int doConnect(String addr, int port) throws RemoteException {
            _connectSocket(addr, port);
            _authentification();
            return 0;
        }
    };


class connectSocket implements Runnable {
        String  addrSocket;
        int portSocket;
        int TIMEOUT=5000;

        public connectSocket(String addr, int port) {
            addrSocket = addr;
            portSocket = port;
        }

        @Override
        public void run() {

            SocketAddress socketAddress = new InetSocketAddress(addrSocket, portSocket);
            try {
                mSocket.connect(socketAddress, TIMEOUT);
                PrintWriter out = new PrintWriter(mSocket.getOutputStream(), true);
                out.println("test42");
                            Log.i("connectSocket()", "Connection Succesful");
            } catch (IOException e) {
                Log.e("connectSocket()", e.getMessage());
                e.printStackTrace();
            }       
        }
    }

    class authentification implements Runnable {

        private String constructFirstConnectQuery() {
            String query = "toto";
            return query;
        }

        @Override
        public void run() {
            BufferedReader  in;
            PrintWriter out;
            String      line = "";

            try {

                in = new BufferedReader(new InputStreamReader(mSocket.getInputStream()));
                out = new PrintWriter(mSocket.getOutputStream(), true);
                out.println(constructFirstConnectQuery());


                while (mSocket.isConnected()) {
                    line = in.readLine();
                    Log.e("LINE", "[Current]- " + line);
                }
            } 
            catch (IOException e) {e.printStackTrace();}

        }
    }
