java - Best way to communicate between an Android App and a JavaFX Application -

i working on javafx music player can communicate android app via tcp sockets, displaying data music player (e.g.: playlist). android app loads list of available music players database. in list there the current ip , current public_port of music player. android app can connect player on tcp socket , public_port. after music player returns "private_port" android app (so app can communicate on private_port player), , starts listening new clients connect.

    public void connecttoserver() {     boolean end = false;     for(int = 0; end == false; i++) {         try {                  if(i > 100) {                 end = true;             }             socket = new java.net.socket(serveraddress,port);              end = true;             port = integer.parseint(getportfromserver());             log.d("", "connected engine on port" + port);             socket.close();             socket = new java.net.socket(serveraddress,port);             readplaylist();             thread.sleep(1000);         } catch (ioexception e) {             e.printstacktrace();         } catch (classnotfoundexception e) {             e.printstacktrace();         } catch (interruptedexception e) {             // todo auto-generated catch block             e.printstacktrace();         }                }  } 

because think not solution, because need alot of tcp ports wondering if there better method implement this.

my idea different implementation restful webservice, sure if work, because using javafx , need executable file launch music player without installing webserver.

edit: idea putting webserver between android app , javafx player. way solve port problem.

solved problem using udp sockets.
