Java 服务器套接字连接问题

我在服务器套接字连接方面遇到了一个问题，我有一个用于这个小游戏的程序，我正在尝试使用套接字来连接它，但是当我到达

serverSocket=newserversocket（53000）它只是停止和冻结，似乎没有去任何地方之后，或采取任何连接。和
kkSocket=新插座（杜克，53000）然后它就崩溃了，似乎没有连接，我已经确保我的防火墙没有打开，我添加了互联网权限，我尝试了很多不同的方法来获取设备名称，我输入了我的设备名称，尝试了当前的ip地址，什么都不会通过，我有一个galaxy nexus和一个nexus 7平板电脑，他们两人在交流时都有问题，任何信息都很好，谢谢

你能给我们看看日志吗？怎么了

第二：当你这样做的时候：

 while (!end){
        Toast.makeText(getActivity().getApplication(),"Open Serveraf",Toast.LENGTH_SHORT).show();
        clientSocket = serverSocket.accept();
        end = serverSocket.isBound();   
    }    

接受第一次连接后，服务器套接字将不再侦听，因为while条件为false。
使用try-catch语句捕获并显示正在发生的任何错误，并缩小问题范围。定义“it just crash”。当你遇到异常时，不要编造你自己的消息，尤其是像“其他错误”一样平庸、内容自由的消息。打印异常附带的消息，最好还打印堆栈跟踪。否则你就没有希望知道出了什么问题，因为你不知道。
