Any Suggestion on addroid app

MeenakshiMadhuraGud Afternoon,
Can anyone Suggest me an android application for college like e-attendence,exam sitings etc

Why not take up the apps that you have mentioned? For attendance, make use of the GPS of the mobiles to track attendance.

You may also look at any Android application and try to replicate it. What say?

But all these are already implemented in our college.. So, i would like to introduce something new..
I have little idea , Our College has bank and the fees we pay there need to submit a hardcopy to the admin to assure that we have paid the fee.. So i need an application which automatically updates to admin our payment..
