SOCKS-5 proxy server on android device without root -

is there way create socks-5 proxy server on unrooted android device? why require root? can make own android application create server on device , use server proxy on compluter, without rooting device?

update: came using this library try create proxy server. downloaded files, added main .jar file project dependencies in androidstudio. there trying start server runnable in service. here service code:

public class proxyservice extends service  {      private static boolean running = false;      @override     public int onstartcommand(intent intent, int flags, int startid) {          serverauthenticatornone auth = new serverauthenticatornone();          proxyserver server = new proxyserver(auth);          run(server); //runnable needed because if start service                       //this thread throws network on main thread exception         return start_sticky;     }      private void run(proxyserver server) {         if (running)             return;          final proxyserver serverfinal = server;         running = true;         new thread(new runnable() {             @override             public void run() {                 while (true) {                     log.i("debug", "tick " + running);                      serverfinal.start(1080);                      log.i("debug", "proxyserver started @ port 1080");                     running = true;                     try {                         timeunit.seconds.sleep(5);                     } catch (interruptedexception e) {                         e.printstacktrace();                         running = false;                     }                 }             }         }).start();     }      @nullable     @override     public ibinder onbind(intent intent) {         return null;     } } 

when run code on xiaomi redmi note 2 unrooted device, following logs:

07-26 16:48:18.097: i/debug(19766): tick true 07-26 16:48:18.099: i/xiaomifirewall(1211): firewall pkgname:com.socks.server, result:0 

and when check proxy using this website nothing.

i think should have configured server somehow, done using external .properties file outside of .jar , not know how link them in androidstudio project.

i suspect these actions require superuser(root) prevent xiaomi firewall refusing me in starting server.

any advice?
