Can't Receive Data from Desktop (Qt C++) to android (java)

Anmol

I have created a Qt project and android project. here Desktop is working as a server and android is the receiver.

Current situation :-

Android is connecting to a server perfectly
Android is sending data and a server receiving data
Server sending data and but android can not receive data <=== My problem)

Android code
->ReadyRead block for reading data

public class mySocket extends AsyncTask<String,String,String>
{

    Socket s;
    DataOutputStream ds;
    String ip,message;
    int port = 1812;
    TextView t1;

    private PrintWriter output;
    private BufferedReader input;

    public mySocket(TextView t1) {
        this.t1 = t1;
    }

    @Override
    protected String doInBackground(String... strings)
    {
        ip = strings[0];
        message = strings[1];


        try {
            s = new Socket(ip,port);

            output = new PrintWriter(s.getOutputStream());
            input = new BufferedReader(new InputStreamReader(s.getInputStream()));

            if(s.isConnected())
            {
                t1.setText("Connected");
                output.write("1");
                output.flush();
            }
            else
            {
                t1.setText("Not connected");
            }
            new Thread(new ReadyRead()).start();
        }
        catch (Exception e)
        {
            e.printStackTrace();
        }
        return null;
    }
    class ReadyRead implements Runnable
    {

        @Override
        public void run() {
            int i = 0;
            Log.e("ReadyRead", "run: Thread Started");
            while (true)
            {
                i++;
               // variable i only prits once (I dont know why)
                Log.e("ReadyRead ", "I = " + i );

                // loop is getting terminated after this line 
               // and also  the log message of try  block not  execute
                try
                {
                    final String message = input.readLine();
                    Log.e("Message From Server", "run: " + message );
                    //t1.setText(message);
                }
                // here the catch block's log message is not print
                catch (IOException e) {
                    Log.e("Error", "run: " + e.getMessage());;
                }
            }
        }
    }
}

Desktop code:-
->Android sending "1" and this function is processing data and sending "1~15".


void MyTcpSocket::myReadyRead()
{
    // get the information
    QString data = socket->readAll();
    qDebug() << socketDescriptor << " Data in: " << data;

    QStringList list = data.split('~');

    bool isFirst = true;
    QStringList dataList ;
    int action;

    for(int i = 0 ;i < list.length() ; ++i)
    {
        if(isFirst)
        {
            action = list.at(i).toInt() ;
            isFirst = false;
        }
        else
        {
            dataList.push_back(list.at(i));
        }
    }

    qDebug() << "serverConnection (myReadReady) : action : " << action;
    qDebug() << "serverConnection (myReadReady) : value : " << dataList;

    switch (action)
    {
        case ALLAction::error :
        {
            qDebug() << "serverConnection (myReadReady) : list : " << list;
            break;
        }
        case ALLAction::getTotaltableNo :
        {
            //sending total table Quantity..
            GlobalData g;
            QString tblNo =  XmlManipulation::getData(g.getTagName(g.QtyTable),g.getattribute(g.QtyTable) );

            QByteArray msg = setAction(ALLAction::getTotaltableNo,tblNo);

            qDebug() << "serverConnection (myReadReady) : ALLAction::getTotaltableNo : sending msg : " << msg ;
            //socket->write(msg);
            QTextStream out(socket);
            out << msg;

            break;
        }
        default:
        {
            qDebug() << "serverConnection (myReadReady) : default case called : " << data;
        }
    }
}
