well i think you should first check the connection between your device and ur server-PC by installing android terminal emulator app on ur device and ping it with your server ip address.....then try to connect your device with server...hope u'll succeed....

You are trying to connect localhost on your PC here:

InetAddress.getByName("vivek-PC").getHostAddress()

If there is no connection between your PC and device, it's so natural that it will fall into UnknownHostException part and not work on your device.

Because your android uses wifi which does not use the name vivekpc, try changing vivekpc to the wifi name of your device.
