다중 룸 채팅 응용 프로그램을위한 SOCKET.IO 서버를 만든 후 https://github.com/socketio/socket.io-client-java을 사용하여 안드로이드 클라이언트를 만드는 방법은 무엇입니까? 안드로이드 용 socket.io의 클라이언트 측에서 최신 예제를 찾았습니다. 대부분의 자습서와 예제는 node.js가있는 서버 측을위한 것입니다.Android Socket.io 클라이언트를 설치하는 방법은 무엇입니까?

는 아래의 안드로이드 링크에서 구현 예를 들어 채팅 애플리케이션했습니다, 나는 가장 좋은 방법은이 같은 서비스 뭔가 내부에 그것을 사용하고 안드로이드에 socket.io를 사용하기위한
https://github.com/nkzawa/socket.io-android-chat
어떤 방식으로 생각 :
public class ChatService extends Service {
public void connectSocket() {
try {
IO.Options options = new IO.Options();
socket = IO.socket("http://192.168.1.1:8080", options);
socket.on(Socket.EVENT_CONNECT, new Emitter.Listener() {
@Override
public void call(Object... args) {
}
}).on(Socket.EVENT_DISCONNECT, new Emitter.Listener() {
@Override
public void call(Object... args) {
}
}).on("error", new Emitter.Listener() {
@Override
public void call(Object... args) {
}
});
socket.connect();
} catch (Exception ignored) {
}
}
@Override
public void onDestroy() {
socket.disconnect();
super.onDestroy();
}
}
