The document discusses the development and architecture of an Android-based alumni application that facilitates communication between past and current students of educational institutions. It outlines the existing inefficiencies in data management and proposes a centralized system for better connectivity and information access. Additionally, it highlights the potential of the Android app ecosystem in transforming lives through information sharing and collaboration.

3. What Is Android?
• It is an open source software platform and operating system for
mobile devices
• Based on the Linux kernel
• Developed by Google and later on led by Open Handset Alliance
(OHA)
• Allows writing managed code in the Java language
• Android has its own virtual machine i.e. DVM (Dalvik Virtual
Machine),which is used for executing the android application.
• Founded by Andy Rubin, Rich Mines, Nick Sears and Chris White
in 2003 and later on purchased by google in 2005.

4. OHA (Open Handset Alliance)
•A software platform and operating system for mobile
devices
• The Open Handset Alliance (OHA) is a business
alliance of many firms whose goal is to develop open
standards for mobile devices, promote innovation in
mobile phones and provide a better experience for
consumers at a lower cost.

5. VERSIONS OF ANDROID

6. ANDROID ARCHITECTURE
The software stack is split into Four Layers:
• The application layer
• The application framework
• The libraries and runtime
• The kernel

7. ANDROID ARCHITECTURE

8. • LINUX KERNEL: This layer is core of android architecture. It provides
service like power management, memory management, security
etc. It helps in software or hardware binding for better
communication.
• NATIVE LIBRARIES: Android has its own libraries, which is written in
C/C++. These libraries cannot be accessed directly. With the help of
application framework, we can access these libraries. There are
many libraries like web libraries to access web browsers, libraries
for android and video formats etc.
• ANDROID RUN TIME: The Android Runtime was designed
specifically for Android to meet the needs of running in an
embedded environment where you have limited battery, limited
memory, limited CPU.

9. • APPLICATON FRAMEWORK: This is all written in a Java
programming language and the application framework is the
toolkit that all applications use.
• APPLICATION LAYER: All the applications like camera, Google
maps, browser, sms, calendars, contacts are native
applications. It includes the home application the contacts
application , the browser, and apps.

10. Software Development
Development requirements:
•1.Java
•2.Android SDK
•3.Eclipse IDE

11. ALUMNI APPLICATION
• The objective of this application is to allow old and
new students of a university or college to
communicate with each other. This allows students
to know about each other and their current
activities.
• The application allows students to register and then
search the data based on different criteria.

12. Existing System
• Many institutions, colleges and universities
maintain the information manually about
present and past students. This does not allow
efficient data management and retrieval
process. A student willing to get information
about others has to approach the college and
obtain the details. Often the information may
not be available and misleading.

13. PROPOSED SYSTEM
• The application allows students to register and
then search the data based on different
criteria. Also it has the benefit of having a
centralized database and up to date
information. A user can easily obtain
information about other registered users.

14. SNAPSHOTS

15. CONCLUSION
• The Android app ecosystem is rich and diverse and their
usage is changing people’s lives. Apps alone aren’t
going to make the world a better place, but the people
developing and using them are working to share
information, teach, collaborate, and grow, and that will
make the world a better place. It already has.
• Android Alumni app is one such attempt to bring the
passed out students of the college closer to their
juniors. It helps them to connect, get information and
guidance for their career.
