在android java中连续发送图像通过udp

Question

我将我的电脑屏幕截图发送到udp上的android选项卡。当图像数据的大小增加时，传输停止。正在发送10 kb的图像，当图像尺寸变为12kb时，不接收图像，如果图像尺寸小于初始接收尺寸，则在标签中接收图像。这背后的原因是什么？我接收数据报包的代码是

   private class Udpreceiver implements Runnable {

        String path = Environment
                .getExternalStoragePublicDirectory(Environment.DIRECTORY_DCIM)
                + File.separator + "Simple";
        File directory = new File(path);
        byte[] incommmingData = new byte[65 * 1024];
        DatagramPacket p = new DatagramPacket(incommmingData,
                incommmingData.length);
        int file_size;


        public void run() {
            try {
                while (true) {
                    datagaramSoc = new DatagramSocket(1546);
                    FileOutputStream outStream = null;
                                    file_Num = file_Num + 1;

                    datagaramSoc.receive(p);

                 file_size = Integer.parseInt(new String(p.getData())
                            .substring(2).substring(0, 5));
                    if (!directory.isDirectory()) {
                        directory.mkdir();
                    }
                    imagePath = new File(path + "/" + file_Num
                            + "SimpleImage.jpg");
                    outStream = new FileOutputStream(imagePath);
                BufferedOutputStream bos = new BufferedOutputStream(
                            outStream);
                    bos.write(p.getData(), FILE_START, file_size);
                    bos.flush();
                    bos.close();
                    outStream.flush();
                    outStream.close();
                    p.setLength(incommmingData.length);
                    runThread(file_Num);
                    datagaramSoc.close();
                }
            } catch (Exception e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            } finally {
                if (datagaramSoc != null)
                    datagaramSoc.close();
            }

        };

    }

请帮我解决这个问题
