Android Notifications

Priority: P2 (MEDIUM)

Implementation Guidelines

Channels: Create NotificationChannel with unique ID (required for API 26+). Notifications without valid channel silently dropped. Use NotificationCompat for backwards compatibility.
Permissions: Explicitly request POST_NOTIFICATIONS on Android 13+ (API 33). Avoid requesting system permission on app launch; show priming dialog first to explain benefit.
Service: Implement FirebaseMessagingService with onMessageReceived and onNewToken for background push handling. Declare service in AndroidManifest with MESSAGING_EVENT intent action.
Flow: Handle notification taps in both onCreate and onNewIntent using PendingIntent. Pass data between activities via Intent extras.
Payload: Limit notification payload to essential IDs. Perform background data fetching via WorkManager if more data needed.

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 declared with MESSAGING_EVENT action.

Prompt

I'm building an Android app that needs to display order status updates in the system tray. Can you write a Kotlin notification manager helper class that creates and posts these alerts, ensuring compatibility across older and newer Android OS versions?

Without the skill loaded, the model failed this case. With it loaded, the same prompt on the same model passed. This is one improved case from the latest verified run; every case, including any that regressed, is in the table above.
