Doorbell Notification Android App

This is the second part of my doorbell audio detection project (first part is audio classification using tensorflow), implementing an Android application that receives and manages notifications from the Raspberry Pi doorbell detection system. The app utilizes Firebase Cloud Messaging (FCM) for receiving notifications and provides a comprehensive logging system to track doorbell events.

Features

• Real-time notifications when doorbell is detected
• Notification logging system with timestamps
• Date-based log filtering
• Log management capabilities
• Material3 design & Native Kotlin implementation
• Support for Android 12+ devices

Requirements

• Android Studio
• Android SDK 31 (Android 12) or higher
• Firebase project setup

Setup Guide

1. Clone the repository

git clone https://github.com/onurds/Doorbell_AndroidApp.git

2. Firebase Configuration

• Create a new Firebase project in the Firebase Console
• Add an Android app to your Firebase project
• Download the google-services.json file
• Place the file in the app directory of your project

3. Build Dependencies

The project uses Gradle with version catalog. Some of the needed libraries included are:

[versions]
androidx-room = "2.6.1"
firebase-bom = "32.7.1"

[libraries]
androidx-room-runtime = { group = "androidx.room", name = "room-runtime", version.ref = "androidx-room" }
androidx-room-compiler = { group = "androidx.room", name = "room-compiler", version.ref = "androidx-room" }
androidx-room-ktx = { group = "androidx.room", name = "room-ktx", version.ref = "androidx-room" }
firebase-messaging = { group = "com.google.firebase", name = "firebase-messaging-ktx" }
androidx-material3 = { group = "androidx.compose.material3", name = "material3" }

4. Android Manifest Permissions

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.POST_NOTIFICATIONS" />

Architecture

• Room Database: For local storage of notification logs
• Firebase Cloud Messaging: For receiving real-time notifications
• Kotlin Coroutines: For asynchronous operations
• Material 3: For modern UI components and theming
• ConstraintLayout: For responsive layouts
