java - read_message in Bluetooth Chat sample -

-

i'm coding android app, , it's connected cc2540 usb dongle bluetooth. procedure that, when dongle sends string "o\r\n" phone, app must view string on edittext "ef". have changed message_read part in bluetooth chat sample android sdk: 

 private final handler mhandler = new handler() {     @override     public void handlemessage(message msg)      {         switch (msg.what)          {          case message_read:             byte[] readbuf = (byte[]) msg.obj;              if (readbuf.equals("o\r\n"))             {                  // construct string valid bytes in buffer                string readmessage = new string(readbuf, 0, msg.arg1);                mconversationarrayadapter.add(mconnecteddevicename+":  " + readmessage);              }          }     } };

is code okay requirements ?

how implements edittext here in case ?

thanks in advance
