Android app based on a website

I need an android app for the usage of students and lecturers in the university. It is actually my school project. It is for the purpose of sharing notes and putting announcements for the students by the lecturers or the university admins through a web controlled app. It need to have a login page for every user including lecturers. Then students gets to register for the subjects they are going to study for that particular semester. They can edit their profile. And the lecture who is in charge of that particular subject can post announcements for the students who have enrolled their subject. eg; Class cancellation, Quiz, etc. There are more details into it. Do contact me a.s.a.p. if you are interested. Thank you.
