TODO::
1) For fetching code of Codeforces gym submissions, password is also required. So currently, no gym submissions will be downloaded.
2) Add check to verify if the handle is valid.

Please give it a try. Update v2:
I have updated the app.
It is now Java7 compatible.
I also added new features — Fetch all AC submissions.
It also includes some bug fixes.
Download here v2

Thanks.
