在android客户端java服务器上连接重置错误套接字连接

Question

我正在从java服务器发送屏幕截图到android客户端抛出套接字 并使用异步任务接收它，它可以正常工作几秒钟并断开连接并显示连接重置

客户代码

    connectTask conctTask = new connectTask();
    conctTask.executeOnExecutor(AsyncTask.THREAD_POOL_EXECUTOR);



    public class connectTask extends AsyncTask<Bitmap,Bitmap,TCPClient> {

    @Override
    protected TCPClient doInBackground(Bitmap... bitmap) 
    {
        //we create a TCPClient object and
        mTcpClient = new TCPClient(new TCPClient.OnMessageReceived() 
        {
            @Override
            //here the messageReceived method is implemented
            public void messageReceived(Bitmap bitmap) 
            {
                try
                {//this method calls the onProgressUpdate
                    publishProgress(bitmap);}
                catch (Exception e)
                {e.printStackTrace();}
            }
        },ip);
        mTcpClient.run();
        if(mTcpClient!=null)
        {
            mTcpClient.sendMessage("Initial Message when connected with Socket Server");
        }
        return null;
    }


    @SuppressWarnings("deprecation")
    @Override
    protected void onProgressUpdate(Bitmap...vbitmap) {
        super.onProgressUpdate(vbitmap);
        if(vbitmap!=null){
            super.onProgressUpdate(vbitmap);
            Bitmap bitmap = vbitmap[0];
            if (bitmap != null) {
               ob = new BitmapDrawable(getResources(), bitmap);


    im.post(new Runnable (){

        @Override
        public void run() {
            // TODO Auto-generated method stub
            im.setBackgroundDrawable(ob);
        }

    });

** Java Server *

    try
         {
          serverSocket = new ServerSocket(SERVERPORT);
         // create client socket... the method accept() listens for a
         // connection to be made to this socket and accepts it.
         try
         {
            client = serverSocket.accept();
            System.out.println("S: Receiving...");
            // sends the message to the client
            mOut = new ObjectOutputStream(client.getOutputStream());
            if (mOut != null)
                            {
                                //Start this thread ie below run()
                            }
        }
        catch (Exception e)
        {
            System.out.println("Error: "+e.getMessage());
            e.printStackTrace();
        }
        finally
        {    

            client.close();

            System.out.println("PA: Done.");
        }
    }
    catch (Exception e)
    {
        System.out.println("PA: Error");
        e.printStackTrace();
    }
    finally
    {    

                try {
                    serverSocket.close();
                } catch (IOException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }


    }
  @Override
public void run()
{
    while(screenCasting)
    {
        try {
        BufferedImage screenShot = rb.createScreenCapture(new Rectangle(Toolkit.getDefaultToolkit().getScreenSize()));

        screenShot.setAccelerationPriority(1);

    ByteArrayOutputStream bis=new ByteArrayOutputStream();

        ImageIO.write(screenShot,"jpeg",bis);
        byte[] buffer=bis.toByteArray();
        mOut.writeObject(buffer);
        mOut.flush();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
  }
}

它可以正常工作几分钟，但在服务器上显示一些错误连接重置
