MOBILE-APP AND WEBSITE

In today's world, the application of information technology and digitalization is considered a crucial factor in the operations of governments, organizations, and companies It plays an extremely important role and can lead to significant breakthroughs With the continuous development of computer technology and electronic networks, information technology has been enhanced by high-level technologies, conquering one peak after another The Internet is one of the most valuable products and has become an indispensable tool, serving as the main platform for global information transmission and exchange

In the digital age, the construction of social networks is one of the most prominent trends Developing a social networking application that runs on multiple platforms has become a

challenge for developers This is why I have chosen the topic "BUILDING A SOCIAL NETWORKING APPLICATION RUNNING ON ANDROID MOBILE-APP AND WEBSITE" for my Specialized Project 1 The aim of this project is to create an advanced

social networking application that can be accessed on various devices, catering to the needs of users Additionally, this topic is relevant to the current reality, as social networks have become

an integral part of people's lives

I would like to express my sincere gratitude to the university, specifically to the Faculty of Computer Science, for their dedicated guidance, valuable feedback, and the opportunities provided to me to successfully complete my research project for Specialized Project 1

I would like to thank D.Sc Le Van Minh for his wholehearted support and guidance throughout the process of conducting and reporting the research

During the execution of this research project, I have made diligent efforts, although some mistakes may still be present I hope to receive valuable input from my professors and the evaluation committee to further improve the quality of my research project

I sincerely thank you!
