java - Client Not Receiving String From Server -

i trying write tcp client using sockets in java, cannot seem read data sent server client. time received server not time..

public class tcpclient {      private string servermessage;     public static final string serverip = "103.13.97.87"; //your computer ip address     public static final int serverport = 8101;     private onmessagereceived mmessagelistener = null;     private boolean mrun = false;      printwriter out;     bufferedreader in;      /**      *  constructor of class. onmessagedreceived listens messages received server      */     public tcpclient(onmessagereceived listener) {         mmessagelistener = listener;     }      /**      * sends message entered client server      * @param message text entered client      */     public void sendmessage(string message){         if (out != null && !out.checkerror()) {             out.println(message);             out.flush();         }     }      public void stopclient(){         mrun = false;     }      public void run() {          mrun = true;          try {             //here must put computer's ip address.             inetaddress serveraddr = inetaddress.getbyname(serverip);              log.e("tcp client", "c: connecting...");              //create socket make connection server             socket socket = new socket(serveraddr, serverport);              try {                  //send message server                 out = new printwriter(new bufferedwriter(new outputstreamwriter(socket.getoutputstream())), true);                  log.e("tcp client", "c: sent.");                  log.e("tcp client", "c: done.");                  //receive message server sends                 in = new bufferedreader(new inputstreamreader(socket.getinputstream()));                  //in while client listens messages sent server                 while (mrun) {                     servermessage = in.readline();                      if (servermessage != null && mmessagelistener != null) {                         //call method messagereceived myactivity class                         mmessagelistener.messagereceived(servermessage);                     }                     servermessage = null;                  }                   log.e("response server", "s: received message: '" + servermessage + "'");               } catch (exception e) {                  log.e("tcp", "s: error", e);              } {                 //the socket must closed. not possible reconnect socket                 // after closed, means new socket instance has created.                 socket.close();             }          } catch (exception e) {              log.e("tcp", "c: error", e);          }      }      //declare interface. method messagereceived(string message) must implemented in myactivity     //class @ on asyncktask doinbackground     public interface onmessagereceived {         public void messagereceived(string message);     } }
