从套接字接收多个字节数组

Question

我目前正在使用远程桌面应用。服务器部分在Android设备上运行，客户端在PC / Raspberry PI上运行。我在接收位图时遇到了问题（来自Android的截图，作为字节数组发送）。 Android Server 代码如下所示：

//os = new ObjectOutputStream(s.getOutputStream());   
   public void run() {
            while(true){
            try {

                View v1 = getWindow().getDecorView().getRootView();
                v1.setDrawingCacheEnabled(true);
                Bitmap bitmap = Bitmap.createBitmap(v1.getDrawingCache());
                v1.setDrawingCacheEnabled(false);

                int quality = 100;

                ByteArrayOutputStream stream = new ByteArrayOutputStream();
                bitmap.compress(Bitmap.CompressFormat.JPEG, quality, stream);
                byte[] byteArray = stream.toByteArray();

                if(byteArray.length>0) {

                    os.writeInt(byteArray.length);

                    os.write(byteArray, 0, byteArray.length);
                    os.flush();
                    }                   
            } catch (IOException e) {
                e.printStackTrace();
            }}}

PC上的 Receiver App 就像这样：

//ois = new ObjectInputStream(s.getInputStream());
public void run() {
         while(true){

        try {
            ByteArrayOutputStream out = new ByteArrayOutputStream();
            int size = ois.readInt();
            System.out.println(size);
            byte[] data = new byte[size];
            int length = 0;


            while ((length = ois.read(data,0,size)) != -1) {
                out.write(data, 0, size);
                out.flush();
            }
            byte[] bytePicture = out.toByteArray();
            out.close();

            BufferedImage buffImage = byteArrayToImage(bytePicture);

            ImageIcon imgIcon = new ImageIcon(buffImage);

            l.setIcon(imgIcon);
            } catch (IOException e) {
        }}}

byteArrayToImage

public static BufferedImage byteArrayToImage(byte[] bytes) {
        BufferedImage bufferedImage = null;
        try {
            InputStream inputStream = new ByteArrayInputStream(bytes);
            bufferedImage = ImageIO.read(inputStream);
        } catch (IOException ex) {
            System.out.println(ex.getMessage());
        }
        return bufferedImage;
    }

问题是在接收器应用程序中我得到Java OutOfMemoryException，因为我在传入的屏幕截图之间无法区分。我真的无法弄清楚如何准确读取位图的大小（作为字节数组）然后显示它并读取另一个和另一个。任何帮助将不胜感激。提前谢谢。
