尝试使用Java中的socketServer向android发送数据
我正在制作某种由android应用程序控制的记分牌 我正在向服务器发送数据，但我试图在我的JFrame和android应用程序上同步分数，但它不起作用 看不出它为什么不工作，我可以从应用程序向服务器发送数据，但不能向后发送，以下是代码：尝试使用Java中的socketServer向android发送数据,java,android,socketserver,Java,Android,Socketserver,我正在制作某种由android应用程序控制的记分牌 我正在向服务器发送数据，但我试图在我的JFrame和android应用程序上同步分数，但它不起作用 看不出它为什么不工作，我可以从应用程序向服务器发送数据，但不能向后发送，以下是代码： public class server { private static ServerSocket serverSocket; private static Socket clientSocket; private static Inp

服务器是否真的接收到客户端发送的命令？你看到它在服务器里了吗？怎么做？printwriter.writemessage；。服务器尝试读取一行。所以客户端应该发送一条线路。更改为printwriter.writemessage+\n；。删除printwriter.close；。您还应该在服务器发送text.switch消息的位置添加该消息。它能编译吗？@greenapps是的，它能编译。我要试着换一下打印机。@Greenty，这很有效！
