我一直有服务器套接字连接的问题，我有一个用于这个小游戏的程序，并试图使用套接字来连接它，但是当我到达它时，serverSocket = new ServerSocket(53000);它只是停止并冻结，之后似乎没有去任何地方或采取任何联系。在那kkSocket = new Socket(duke, 53000);之后它就崩溃了，似乎没有连接，我确定我的防火墙没有打开，我添加了互联网权限，我为设备名称尝试了许多不同的东西，我输入了什么我已经命名了我的设备，尝试了当前的 IP 地址，但什么都不会通过，我有一个 Galaxy nexus 和一个 nexus 7 平板电脑，它们在尝试相互通信时都有问题，任何信息都会很好，谢谢。
