Case Study
A native Android application built in Java, demonstrating mobile UI development, activity lifecycle management, and Gradle-based project configuration.
View on GitHub01 — Problem
Mobile application development introduces a distinct set of constraints compared to web or desktop software — limited screen real estate, activity lifecycles, device fragmentation, and build tooling that differs from standard Java development. The challenge was to build a functional Android application from scratch in Java using the Android SDK, navigating the full project structure: Gradle build configuration, activity management, and UI layout — without relying on modern abstraction layers like Jetpack Compose, to ensure foundational understanding of how Android applications work at the core level.
02 — Action
Developed a native Android application using Java and
the Android SDK, designing UI layouts and
implementing activity lifecycle callbacks (onCreate,
onResume, onPause) to manage application
state correctly across device events such as screen rotation and
backgrounding. Configured the project using
Gradle build scripts to manage dependencies, define
build variants, and produce a deployable APK. Applied object-oriented
design principles throughout — structuring the application into
logical classes with clear responsibilities, mirroring patterns used
in production Android development.
03 — Result
Delivered a functional Android application with a working UI, correctly managed activity lifecycle, and a clean Gradle build configuration. Built foundational mobile development skills — Java OOP, Android SDK patterns, and Gradle toolchain — that transfer directly to Android engineering roles and cross-platform mobile frameworks. The project reinforced that mobile constraints require deliberate architectural decisions, a principle that applies broadly across any resource-constrained computing environment.
