I have followed the instructions in guidelines, but after entering the command “adb –d forward tcp:8230 tcp:8230” I am getting output as following on cmd : 

  adb sync [ <directory> ]     – copy host->device only if changed
                                 (-l means list but don’t copy)
                                 (see ‘adb help all’)
  adb shell                    – run remote shell interactively
  adb shell <command>          – run remote shell command
  adb emu <command>            – run emulator console command
 

environmental variables:

  ADB_TRACE                    – Print debug information. A comma separated list
 of the following values
                                 1 or all, adb, sockets, packets, rwx, usb, sync
, sysdeps, transport, jdwp
  ANDROID_SERIAL               – The serial number to connect to. -s takes prior
ity over this if given.
  ANDROID_LOG_TAGS             – When used with the logcat option, only these de
bug tags are printed.

And the Device isn’t getting connected with the emulator.
