Socket을 기반으로 클라이언트 (android) -server (java) 앱을 작성하고 있습니다. 내 문제는 서버에서 두 가지 유형의 메시지 (MINDWAVE 및 SPHERO)를 처리해야한다는 것입니다. mindwave 메시지는 서버에 의해 잘 처리되지만 sphero 하나에 문제가 있습니다. -client는 "SPHERO"메시지를 보내십시오. -server는 "Sphero 요청이 중단되었습니다." (루프의 첫 번째 작업을 시작하지 않습니다 - 그냥 readline에 붙어있다 ((에서 fromServerLoad() =!) 루프 ") 부분).Android 클라이언트 - 서버 앱 - readLine() 작동하지 않습니다.
클라이언트의 스레드
class SendSpheroRequest extends AsyncTask<Void, Void, Void> {
String fromServer = "";
int movement;
@Override
protected Void doInBackground(Void... params) {
try {
Thread.sleep(2000);
} catch (InterruptedException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
while (isActive) {
try {
socket = new Socket(address, port);
Thread.sleep(1000);
out = new PrintWriter(socket.getOutputStream(), true);
out.write(TAG);
out.flush();
out.close();
socket = new Socket(address, port);
in = new BufferedReader(new InputStreamReader(
socket.getInputStream()));
while ((fromServer = in.readLine()) != null) {
Toast.makeText(getApplicationContext(), fromServer,
Toast.LENGTH_SHORT).show();
if (!fromServer.equalsIgnoreCase("")) {
try {
movement = Integer.parseInt(fromServer);
if (movement > 0) {
driveUp();
} else if (movement < 0) {
driveDown();
}
tvPosition.setText(movement + "");
} catch (Exception e) {
e.printStackTrace();
movement = 0;
}
fromServer = "";
}
}
Thread.sleep(1000);
} catch (UnknownHostException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
try {
socket.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return null;
}
}
그리고 서버의 메시지 처리 :이 줄 바꿈하거나 스트림이 닫힐를 읽을 때
public void processMessage(String message) {
Message messageObject = new Message(message);
if (messageObject.getClientType() == DEVICE_TYPE.MINDWAVE) {
System.out.println("Message sent by "
+ messageObject.getClientType() + " with ID="
+ messageObject.getClientID() + ". The attention value is "
+ messageObject.getAttention());
switch (messageObject.getClientID()) {
case 1: {
if (firstClientIterator < 5 && gameStarted
&& messageObject.getAttention() != 0) {
firstClientAttentionSum += messageObject.getAttention();
firstClientIterator++;
System.out.println("sum=" + firstClientAttentionSum
+ " iterator=" + firstClientIterator);
}
}
break;
case 2: {
if (secondClientIterator < 5 && gameStarted
&& messageObject.getAttention() != 0) {
secondClientAttentionSum += messageObject.getAttention();
secondClientIterator++;
System.out.println("sum=" + secondClientAttentionSum
+ " iterator=" + secondClientIterator);
}
}
break;
default:
System.err
.println("Cannot process the message. Hint: wrong id detected.");
}
} else if (messageObject.getClientType() == DEVICE_TYPE.SPHERO) {
System.out.println("Sphero request catched.");
try {
toClientPrintWriter = new PrintWriter(clientSocket.getOutputStream(), true);
if (firstClientIterator == 5 && secondClientIterator == 5) {
int difference = firstClientAttentionSum
- secondClientAttentionSum;
System.out.println("Sending data to Sphero. "
+ "The difference is " + difference + ".");
firstClientIterator = secondClientIterator = firstClientAttentionSum = secondClientAttentionSum = 0;
toClientPrintWriter.println(difference+"");
} else {
toClientPrintWriter.println("No results yet.");
}
toClientPrintWriter.flush();
toClientPrintWriter.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
