Hey Vasni,
This forum is meant for the discussion of the App Engine and Cloud Platform services, and while it appears that ODK (just Googled this) possibly runs on App Engine, it's very unlikely anyone here has the necessary experience to advise you on how to proceed. I think you would have much better luck following the
links on the ODK website which point to their community and issue tracker, etc. They also appear to have some documentation and usage instructions.
Best of luck,
Nick
