Android Notifications

Priority: P2 (OPTIONAL)

Push notifications using Firebase Cloud Messaging.

Guidelines

• Service: Implement FirebaseMessagingService for handling background messages.
• Channels: Must create NotificationChannel for Android 8.0+ compatibility.
• Permissions: Request POST_NOTIFICATIONS explicitly on Android 13+.
• Intents: Handle notification taps in both onCreate and onNewIntent.
• Priming: Show benefit dialog before requesting system permissions.

Implementation Details

Anti-Patterns

• No Missing Channel: Notifications fail silently without channels on API 26+.
• No Unconditional Requests: Don't spam permission dialog on first launch.
• No Missing Manifest: Service must be declared with MESSAGING_EVENT action.
