求看看这段socket 代码为什么执行不下去了，多谢

    // receiver class    class ServerListener extends Thread{        Socket serverSocket = null;                @Override        public void run() {            while(true){                try {                    Log.w(TAG_LISTENER, "ServerListener run() {");                    serverSocket = mSocket.accept();                                        BufferedInputStream in = new BufferedInputStream(serverSocket.getInputStream());                                        byte[] reader = new byte[10];                    int count = 0;                    boolean flag = false;                    while((count = in.read(reader))>0){   <---  执行不下去了                        flag = true;                        bq.enQueue(reader[0]);                        Log.w(TAG_LISTENER, reader.toString() + " is added to byteQueue");                    }                    Log.w(TAG_LISTENER, "***** ServerSender start");                                        if(flag){                        new ServerSender(serverSocket).start();                        flag = false;                    }                } catch (IOException e) {                    e.printStackTrace();                }            Log.w(TAG_LISTENER, "}");            }        }    }
