The Android Expense Splitter is a Java project that combines Recycler lists and Permissions, built with Gradle. The project follows a clean, modular architecture where input handling, business logic, and presentation stay separated, making it easy to test, extend, and present. It showcases practical Java techniques while producing a working, demo-ready application.
Manual and paper based methods for this task are slow, error-prone, and hard to manage. Without a Java application built on Permissions and Gradle, users cannot process, store, and manage data efficiently, and there is no reliable, reusable way to run the workflow.
This project applies Java techniques through Recycler lists, orchestrated with Gradle and Permissions. The application is designed for correctness and usability, with clean data flow, validation, and error handling. It produces consistent, reusable results and can be adapted to related tasks with minimal changes.

Modular Java application around Recycler lists and Permissions
Configurable settings and validation rules
Clear logging, error handling, and reporting
Clean interface for user interaction
Reusable components for related features
Unit testing and maintainable code
The project is layered: the input layer handles user interaction through Recycler lists; the logic layer implements business rules with Gradle and Permissions; and the output layer presents results via Activities and fragments. Shared validation, storage, and logging modules support all layers, keeping the application robust and easy to extend.
