json 서버를 보내고 json을 listview에 표시하려고합니다. listview는 refreshViewModels() 메소드로 처리됩니다. 전송중인 json 문자열은 다음 코드 줄에 있습니다.Android SocketException - 서버에서 정보를받지 못했습니다.

outputJSONserv = "{\"to \ ": \"type \ ": \"1 \ ", \"payload \ ":"+ outputJSON + "}"; 여기서 outputJSON은 json 문자열입니다.

이 문자열을 보낼 때 한 전화에서는 문자열이 반환되지만 다른 문자는 그렇지 않습니다. 내가 logcat에 내 출력 JSON에 대한 SocketException과 관련이 있다는 오류가 있다는 경고가 표시됩니다.

refreshViewModels() 메소드 :

여기 
public void refreshViewModels(String inputJSON) { 

     try { 
      ListView servicesListView = (ListView) this 
        .findViewById(R.id.profilesListView); 

      String[] from = new String[] { "profilePic", "neighborName", 
        "tagLine" }; 
      int[] to = new int[] { R.id.avatar, R.id.username, R.id.email }; 

      // prepare the list of all records 
      List<HashMap<String, Object>> fillMaps = new ArrayList<HashMap<String, Object>>(); 
      List<Profile> profiles = new ArrayList<Profile>(); 

      // Clear the position mapping list and reset it 
      this.posMap.clear(); 
      Log.i(LOG_TAG, "NEW inputJSON: " + inputJSON); 
      inputJSON = getPayloadStr(inputJSON); 
      Log.i(LOG_TAG, "NEW inputJSON2: " + inputJSON); 
      JSONArray profileArray = new JSONArray(inputJSON); 

      for (int i=0; i<profileArray.length(); i++) { 
       JSONObject jsonObject = profileArray.getJSONObject(i); 
       Gson gson = new Gson(); 
       Profile p = gson.fromJson(gson.toJson(jsonObject).toString(), Profile.class); 
       profiles.add(p); 
      } 

      int pos = 0; 

      // Creates the fillMaps list for the listAdapter 
      Log.i(LOG_TAG, "Profiles size: " + profiles.size()); 
      //showToast("Profiles size: " + profiles.size()); 
      for (Profile p : profiles) { 
       // Create mapping for list adapter 
       HashMap<String, Object> map = new HashMap<String, Object>(); 
       map.put("profilePic", 
         p.getAttributeValue("photo")== null? "Not Set" : p 
           .getAttributeValue("photo")); 
       map.put("neighborName", 
         p.getAttributeValue("Name") == null? "Not Set" : p 
           .getAttributeValue("Name")); 
       map.put("tagLine", 
         p.getAttributeValue("TagLine") == null? "Not Set" : p 
           .getAttributeValue("TagLine")); 
       fillMaps.add(map); 

       // Reset the postion mapping 
       this.posMap.put(pos++, p); 

      } 

      ListAdapter servicesListAdapter = new myAdapter(this, fillMaps, 
        R.layout.listitem, from, to); 
      servicesListView.setAdapter(servicesListAdapter); 

     } catch (Exception e) { 
      Log.e(LOG_TAG, "Error making list adapter: " + e.getMessage()); 
     } 

    }

내 변환 방법은 다음과 같습니다

다음 
public String ConvertByteArrayToString(byte[] b) { 
    // byte[] to string 
    String input = new String(b); 
    return input; 
} 

public byte[] ConvertStringToByteArray(String str) { 
    // string to byte[] 
    byte[] bytes = str.getBytes(); 
    return bytes; 
}

내가 JSON 문자열을주고받을 사용하고 방법은 다음과 같습니다

public void sendBytes(byte[] myByteArray, int start, int len) throws IOException { 
    if (len < 0) 
     throw new IllegalArgumentException("Negative length not allowed"); 
    if (start < 0 || start >= myByteArray.length) 
     throw new IndexOutOfBoundsException("Out of bounds: " + start); 
    // Other checks if needed. 

    // May be better to save the streams in the support class; 
    // just like the socket variable. 

    OutputStream out = socket.getOutputStream(); 
    DataOutputStream dos = new DataOutputStream(out); 

    dos.writeInt(len); 
    if (len > 0) { 
     dos.write(myByteArray, start, len); 
    } 

    //OutputStream out = socket.getOutputStream(); //COMMENTED THIS OUT 

    //DataOutputStream dos = new DataOutputStream(out); //COMMENTED THIS OUT 

    /*dataOutputStream.writeInt(len); //COMMENTED THIS OUT 
    if (len > 0) { 
     dataOutputStream.write(myByteArray, start, len); 
    }*/ 
} 

public static byte[] getBytesFromInputStream(InputStream is) throws IOException { 
     // Get the size of the file 
     int length = is.available(); 

     if (length > Integer.MAX_VALUE) { 
     // File is too large 
     } 

     // Create the byte array to hold the data 
     byte[] bytes = new byte[(int) length]; 

     // Read in the bytes 
     int offset = 0; 
     int numRead = 0; 
     while (offset < bytes.length 
     && (numRead = is.read(bytes, offset, bytes.length - offset)) >= 0) { 
     offset += numRead; 
     } 
     // Ensure all the bytes have been read in 
     if (offset < bytes.length) { 
     throw new IOException("Could not completely stream "); 
     } 
     // Close the input stream and return bytes 
     is.close(); 
     return bytes; 
}

SocketException: socket is closed은 소켓을 닫은 다음 계속 사용함을 의미합니다. 코드의 버그입니다. 스트림 중 하나를 닫고 다른 스트림을 여전히 사용하려고 시도하고 있습니다. 두 스트림 중 하나를 닫으면 다른 스트림과 소켓이 닫힙니다.

또한 available()를 오용하고 있습니다. Javadoc을 참조하십시오. Javadoc에서 유효하지 않은 것으로 명시되어있는 용도로 사용하지 않습니다.

available()을 어떻게 사용 하시겠습니까? 입력 스트림의 크기는 어떻게해야합니까? – user268397

@ user268397 available()을 전혀 사용하지 않는 것이 좋습니다. 그것의 정확한 사용법은 거의 없으며, 이것도 그 중 하나가 아닙니다. '입력 스트림의 크기'와 같은 것은 존재하지 않습니다. 당신은 영원히 계속해서 쓸 수 있습니다. * message * 크기를 알아야 할 경우, (a) 길이 단어 접두어를 보내십시오. (b) 모호함을 일으키지 않는 (즉, 분리 문자가 데이터에 나타날 수없는 경우), 또는 (c) XML, Java Object Serialization과 같은 자체 기술 프로토콜을 사용하는 경우, 개행 문자와 같은 고유 한 후행 분리 문자를 전송하십시오. JSON 등 – EJP

나는 실제로 그것을 지금 사용하지 않을 것이다. 나는 그것을 알아. 조언 해 주셔서 감사합니다! – user268397
