Day 5 of Becoming an Android Developer: Building My First App Interface
Hello, fellow developers and enthusiasts!
Today marks the 5th day of my Android development journey, and I must say, it has been an exciting ride so far! Compared to the previous sessions, today's lecture was shorter, but it packed the same punch in terms of effectiveness. I learned something new, put my skills to the test, and most importantly, had a ton of fun.
Building the Interface for a Unit Converter App
The highlight of today's session was designing the interface for a Unit Converter App! Yes, I finally got to build the front end of an actual application. It might not be a complex app yet, but it’s a start, and I’m genuinely proud of it.
My instructor, Denis Panjuta, walked us through the core basics of interface building. He introduced us to two key concepts for designing UI in Android:
XML: The traditional method for creating layouts in Android. It's a declarative way to structure the user interface.
Jetpack Compose: The modern and reactive approach to UI building in Android. I found this particularly interesting because it makes designing so much simpler and cleaner.
Sir Denis also showed us how to use the Preview function. This handy feature allows us to see our interface in real time without running the app on an emulator. I loved this because it gave me a clear picture of what I was building as I wrote the code.
A Simple Interface But Big Learning
I didn’t build anything too complicated today — the interface is fairly simple, and it’s for a basic Unit Converter app. However, even with a simple UI, I learned so much about structuring layouts, aligning components, and creating a user-friendly interface. I was able to place elements like input fields, labels, and buttons for converting units such as:
Centimeters
Meters
Feet
Inches
It was such a satisfying experience to see the app slowly take shape on the screen. Even though it’s not yet fully functional, this small step made me feel like I was really building something. For the first time, I could see the result of my efforts visually.
Tomorrow: Adding the Logic
What makes me even more excited is tomorrow’s class! While today was all about the interface, tomorrow we dive into the logic of the app. With the guidance of Denis, I’ll implement the code that will actually convert units and make the app functional. I can’t wait to bring this project to life and see it work end-to-end.
Final Thoughts
Today was interactive, fun, and filled with hands-on learning. The process of building an interface, even a simple one, showed me how creative and rewarding Android development can be. I now understand why so many developers enjoy working on UI design.
Stay tuned for tomorrow's update as I take this project one step further. Trust me, it’s going to be a lot of fun!
Happy coding, and see you tomorrow!
