안드로이드 클라이언트/자바 서버 2 웨이

Question

서버

내 생각이 쪽이 괜찮습니다하지만 난 확실하게 그냥 넣어 것이라고 말했다.

import java.io.*; 
import java.net.*; 
public class Server_wifi { 
    public static void main(String[] args) throws Exception { 
     ServerSocket sersock = new ServerSocket(3000); 
     System.out.println("Server ready for chatting"); 
     Socket sock = sersock.accept();       
     // reading from keyboard (keyRead object) 
     BufferedReader keyRead = new BufferedReader(new InputStreamReader(System.in)); 
     // sending to client (pwrite object) 
     OutputStream ostream = sock.getOutputStream(); 
     PrintWriter pwrite = new PrintWriter(ostream, true); 

     // receiving from server (receiveRead object) 
     InputStream istream = sock.getInputStream(); 
     BufferedReader receiveRead = new BufferedReader(new InputStreamReader(istream)); 

     String receiveMessage, sendMessage;    
     while(true) { 
      if((receiveMessage = receiveRead.readLine()) != null) { 
       System.out.println(receiveMessage);   
      }   
      sendMessage = keyRead.readLine(); 
      pwrite.println(sendMessage);    
      System.out.flush();        
     }    
    }      
} 

클라이언트가 나는 문제가 클라이언트 측에 있지만 정말 어디에 알아낼 수없는 것 같아요.

내 앱이 충돌하는 것 같습니다. 완료하지 못했다고 계속 말합니다. 전화와 컴퓨터 사이에 양방향 시스템을 설치하려고합니다. 도움을 청하십시오. 나는 앱이 응답을 계속해서 올리도록 제안하는 것과 같은 포획을했다.

Answer 1

클라이언트와 서버 측 모두에서 을 호출 한 후 대신 pwrite.flush()을 호출해야합니다 (pwrite.println(sendMessage)). 잘못된 출력 스트림을 플러시하고 있습니다.
