我正在使用KryoNet和Javax Swing我在Android设备上运行我的应用时出现问题。首先我在NoClassDefFoundError上获得com.esotericsoftware.krynet.Client。我发现这很奇怪，因为它在核心项目中被引用，并且应该像其他所有Java jar一样，可以在Android项目中访问。
所以我也将kryonet添加到了android libs文件夹中，并摆脱了这个错误。但随后为Javax swing弹出了同样的错误。我相信这些类驻留在java rt.jar中，所以我做了同样的事情，但这给我一个GC overhead limit exceeded错误。
我似乎无法让我的客户端运行，下面是logcat转储：

它停在需要Swing的第一行。在我的服务器应用程序上，Swing工作正常，只是没有客户端那样的摇摆gui。 Afaik swing应与android兼容。下面是我的代码断开的行，类ChatClient上的第84行。
String input = (String)JOptionPane.showInputDialog(null, "IP:",
"Connect to lobby", JOptionPane.QUESTION_MESSAGE,
null, null, "127.0.0.1");
在服务器端，这是工作，我使用一个简单的摆动Jframe（但是我的Android设备上没有显示。所以也许android与swing不兼容，我仍然确定我读它应该变换swing在Android上将窗格简化为UI。

Android不支持Swing图形库，因为它拥有它。使用AlertDialog。

Android手机没有javax.swing套餐。您将不得不为您的应用程序计算其他内容。
