# 🚀 Features

- 🔔 Live Notifications support on Android 16
- ☁️ Firebase Cloud Messaging integration
- 📦 Payload handling and dynamic content updates
- 📱 Local notification example to simulate live updates without a backend
- 💡 Best practices for targeting Android 16+ notification behavior

# 📦 What’s Inside

- Sample app written in Kotlin
- Firebase integration (with sample payload format)
- Notification channel setup and management
- Code examples to create/update live notifications

# 🔧 Requirements

- Target SDK 36 (Android 16)
- Firebase project (for push notifications)

# 📚 Getting Started

### 1️⃣ Clone the Repository <br />

### 2️⃣ Set Up Firebase

- Go to Firebase Console and create a new project (or use an existing one).
- Add an Android app to the Firebase project using your app’s package name.
    - 💡 Tip: You can change the application ID (package name) in build.gradle to match your
      preferred namespace (e.g., com.yourname.app).
- Download the google-services.json file and place it in the /app directory.
- Enable Firebase Cloud Messaging (FCM) in the Firebase Console under Build > Cloud Messaging.
- Launch the app and tap the "Get FCM Token" button:
    - The token will be shown in a toast and logged in Logcat
    - Copy this token for sending test messages

### 3️⃣ Run the App

- Connect a physical device or use an emulator running Android 16
- Press Run in Android Studio to build and install the app

### 4️⃣ Test Live Notifications <br />

🔹 Option A: Test with Local Notification

- Tap the "Send Local Notification" button in the app
- It creates a live progress notification based on a local NotificationModel instance

🔹 Option B: Test with Firebase Console

- Go to Firebase Console > Cloud Messaging > Send Your First Message
- Enter a title and body (these will be overridden by data payload)
- Open Advanced options → Data
- In the Target section, select Single Device
- Paste the FCM token from the app
- Add the following key-value pairs:

### 📝 Example FCM Payload

```json
{
  "title": "Live Update Remote Title",
  "body": "Live Update Remote Body",
  "currentProgress": "80",
  "currentProgressSegmentOne": "33",
  "currentProgressSegmentTwo": "33",
  "currentProgressSegmentThree": "33",
  "currentProgressSegmentFour": "33",
  "currentProgressPointOne": "33",
  "currentProgressPointTwo": "66",
  "currentProgressPointThree": "99"
}

```

- Click Send Message

📌 The payload demonstrates segmented and point-based progress tracking in a live notification,
  perfect for use cases like order tracking, fitness goals, or download status.
