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.

i have order , ordersearch models. in order list (actionindex) gridview there filtering , sorting. on of columns in order order_total (sum of products in order). i need implement sum of order_total in gridview. if manually counting activedataprovider->getmodels() array_map spend 3 seconds 3000 orders (localhost). don't want miss time. i see 2 ways make faster: create cache every filter , update lifetime (horrible) the interesting can right in ordersearch->search() method $query method. don't understand how can pass in controller. example of code 2nd way: class ordersearch extends order { public $totalsum; public function search($params) { $query = order::find(); $dataprovider = new activedataprovider([ 'query' => $query, ]); $this->load($params); $this->totalsum = $query->sum('order_total'); // works fast return $dataprovider; } } after i...

Sass watch command compiles .scss files before full sftp upload -

i use winscp download , edit .scss files , sass on linux (on server) compile them .css . after saving file, use: sass scss/style.scss css/style.css , replaces css file compiled sccs. the problem i want skip part return command line after editing scss file, sake of automation , saving time. but, if use watch command: sass --watch scss/style.scss:css/style.css synchronize 2 files, alerts nonexistent css errors pop up: change detected to: scss/style.scss error scss/style.scss (line 232: invalid css after "...ht: bold; line-": expected "{", "") note that when file uploads quicker usual (sometimes happens) watch command job, no errors. this because, when file upload takes time, sass compiles scss file (on server) before uploaded remote folder. thus, compiles part of file, resulting in css errors. is there way set timer watch command waits few seconds after detects changes , before compiling? any other way overcome is, of course, ...
