java - Android serversocket only reads inputs on the first run -

i creating simple multiplayer android game. devices share information each other using sockets/serversockets. program works fine first run after compilation, if close application , start again program not work. here snippet of server code:

public void listen() {         try {             /**              * creates new server socket. passing in 0, device select              * available port open. makes possible avoid having hardcode              * port.              */             if (serversocket == null)                 serversocket = new serversocket(0);              // sets port generated server port             setlocalport(serversocket.getlocalport());              // run until program stops             while (!stop) {                 // make server socket listen input                 setsocket(serversocket.accept());                 log.d(tag, "socket opened");                  // creates buffered reader in order read input                  input = new bufferedreader(new inputstreamreader(socket.getinputstream()));                  // listen messages                 while(!thread.currentthread().isinterrupted()) {                     try {                         // reads line                         string line;                         line = input.readline();                          // if line not null call onreceive                         if (line != null) {                             onreceive(line);                             log.d(tag, "received: " + line);                         }                         log.d(tag, "received something");                     } catch (ioexception e) {                         log.d(tag, "error");                     }                     break;                 }                 // close input                 input.close();                 log.d(tag, "socket closed");             }         } catch (ioexception e) {             e.printstacktrace();         }     } 

when code works following logcat messages:

05-08 15:00:54.186 11947-11965/com.example.trommemand.playerapp d/net﹕ socket opened 05-08 15:00:54.186 11947-11965/com.example.trommemand.playerapp d/net﹕ received: ok 05-08 15:00:54.186 11947-11965/com.example.trommemand.playerapp d/net﹕ received 05-08 15:00:54.186 11947-11965/com.example.trommemand.playerapp d/net﹕ socket closed

however, when not work following:

05-08 15:00:54.186 11947-11965/com.example.trommemand.playerapp d/net﹕ socket opened 05-08 15:00:54.186 11947-11965/com.example.trommemand.playerapp d/net﹕ socket closed

i suspect problem fail close sockets. have tried close serversocket, gives me error due line: setsocket(serversocket.accept());

any suggestions?

always close resources in finally block. try closing input.close in finally block... this:

           {                       try {                         input.close();                      } catch (ioexception e) {                          e.printstacktrace();                     }                  } 

see if works..
