Expense Tracker & Budget Planner

This Android application helps users record daily expenses and income, assign them to categories (food, travel, bills, etc.), and set monthly budget limits per category. When a budget is close to being exceeded, the app raises a local notification.

All transactions are stored in a local Room database, and MPAndroidChart is used to render pie and bar charts summarizing spending by category and by month. A CSV export feature lets users back up their transaction history.

The UI is built around a dashboard showing total balance, recent transactions, and budget-progress bars, with a simple bottom sheet for quickly adding a new transaction.

Detailed Project Description

Expense Tracker & Budget Planner gives the user a focused everyday tool with a clean interface, local storage of their data and optional sync or reminders.

How It Works
1. The user enters or records data (amounts, steps, notes, recordings, values).
2. The app validates and stores it locally (SQLite/Room/SharedPreferences) or in the cloud.
3. Lists, totals, charts or conversions are computed and displayed instantly.
4. Reminders/notifications run in the background where the feature applies.

Technology Roles
- Android
- Java
- Room
- MPAndroidChart

Implementation Steps
1. Sketch the screens and the data each screen needs.
2. Create the project in Android Studio, Room, MPAndroidChart and set up navigation between screens.
3. Define the local data model (SQLite/Room/SharedPreferences) or cloud sync.
4. Implement the core feature (tracking, conversion, recording, reminders, playback).
5. Add background work / notifications / permissions where required.
6. Test on real devices, handle edge cases and optimise battery and performance.
7. Generate the APK and prepare screenshots and documentation.

Key Features
- Simple, fast UI
