This paper is aimed at developing an Online Application for students and college management. The main theme of the project is to develop an application that enables the students to perform the activities like fee payment, downloading learning materials, and get notifications about the attendance, results, etc; in a mobile application, It provides a simple interface for the maintenance of the student records. In the previous system, all the details have to view in a file or on a website. At the same time while searching for information it takes a long time to get the results. To overcome this an Android Application can be used to make this process much better. All the important data such as passwords are securely stored with the help of hashing techniques. The users of this application are students, Faculty, and Admin. The Faculty can log in to the application and can update the Attendance and Marks of the student. In case of any events or exams in the college, the students will be notified by Admin. As we are college students we know about these problems that we are facing due to the lack of this kind of application. So we thought of extending and solving some of the problems in our project so that it could be more useful for the students and they can easily use the application which is also very compatible for the teachers and students. The data relating to students is stored in Firebase. A web-based portal is designed for the faculty to upload the marks, results, and upload materials.
