ThunderRAR is a native Android application written in Java that gives businesses a single entry point for employee authentication and operational module access. Employees log in with a username and password, while customers can reach a dedicated client view directly from the login screen. Once authenticated, employees land on a dashboard that surfaces four business modules — Sales, Community, Logistics, and Reports — all within a clean, Material-themed interface. The app is self-contained: no backend server is required, and all credential data is stored on-device using SQLite.

​
Key screens

Login

The app’s entry point. Employees enter their username and password to authenticate, or navigate to registration and the client view from here.

Registration

New employees supply a username and password. On success, a new MainActivity is started with the credentials passed as Intent extras ("dato" and "dato2").

Menu

The main business dashboard, reached after a successful login. Displays the four operational modules: Venta, Comunidad, Logística, and Reporte.

Client

A separate view for customers, accessible directly from the login screen without requiring employee credentials.

Tech stack

  • Java (Android) — all activity logic is written in Java targeting the Android SDK
  • AndroidX AppCompat 1.7.0 — backward-compatible Activity and UI primitives
  • Material Components 1.12.0 — buttons, text fields, and theming following Material Design
  • ConstraintLayout 2.2.1 — flexible, flat XML layouts for all screens
  • SQLite via SQLiteOpenHelper — on-device relational database; the BaseDeDatosUsers helper manages the users table with usuario (primary key) and password columns
ThunderRAR v1.0 is an introductory software engineering course final project built at Universidad Autónoma del Perú. The feature set is intentionally scoped to demonstrate core Android concepts — Activity lifecycle, Intent-based navigation, and local data persistence — with the four business module screens planned for future releases.
