You need to stop posting multiple threads about the same topic. That is not allowed here. If you do not get an answer immediately, be patient. Also, stop relying on us for code. We are not obligated to write the application and you will not learning anything from us doing so. Sit down, write down (on paper) what it is you need to do and try to translate it into code. If you are not capable of doing something, then back-peddle and work on something easier.

If you are a newbie at android programming (and from the sound of it, you are a newbie at programming in general), you should NOT be doing a networking project. Start small.
