Voice Recorder App with Cloud Backup

This project is an Android voice-recorder application that lets users capture audio memos using MediaRecorder, browse recordings in a list with duration and waveform preview, and play them back with seek control via MediaPlayer.

Each recording can be tagged with a title and category, and metadata is stored locally in Room while the audio file itself is saved to app-specific storage. An optional cloud-backup feature uploads selected recordings to Firebase Storage, with a progress indicator and a toggle for Wi-Fi-only uploads to avoid unexpected data usage.

The app renders a simple waveform visualization during both recording and playback using a custom View that reads amplitude samples, and includes basic recording management: rename, delete, and share as an audio file via other apps.

Detailed Project Description

Voice Recorder App with Cloud Backup 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
- MediaRecorder
- Firebase Storage
- Room

Implementation Steps
1. Sketch the screens and the data each screen needs.
2. Create the project in Android Studio, Firebase Storage, Room 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
- Offline storage
- Summaries and charts
- Notifications / sync where applicable

Expected Output
On completion the student will have an installable app that keeps the user's data organised and accessible.
