Live Update Notification Android

This repository provides a working example of implementing Live Update Notifications on Android 16 ( Android U). It demonstrates how to leverage both Firebase Cloud Messaging (FCM) and local notifications to deliver rich, timely updates to the user.

Examples

🚀 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

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

🔹 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

{
  "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.
