Error while connection with local ip address in android application

I am making an Android Application in which I need to make a connection with Local Ip address I searched a lot and found same sample code which i tried to implement in my code

http://android-er.blogspot.in/2011/01/simple-communication-using.html

But problem is this that i am unable to connect to IP address bearing no 10.19.21.128 And Port no 8221.

I cannot found where i am missing.If anyone has done this before or has idea or any sample which there is communication between android app and ip address then i will be thankful to him.
