How do you implement push notifications in mobile apps?

Implement push notifications by integrating platform services (FCM for Android, APNs for iOS) and configuring backend services to send targeted messages.

Implementing push notifications requires coordination between your mobile app, backend services, and platform-specific notification services. For Android, integrate Firebase Cloud Messaging (FCM), while iOS uses Apple Push Notification service (APNs). Cross-platform frameworks like React Native can use libraries such as @react-native-firebase/messaging to handle both platforms.

Start by configuring platform services: register your app with FCM/APNs, obtain necessary certificates and keys, and configure your app's capabilities. In your mobile app, implement notification permissions requests, typically shown during onboarding or when users opt into specific notification types.

Backend integration involves storing device tokens when users register, implementing notification targeting logic, and creating APIs to trigger notifications based on user actions or scheduled events. Use services like Firebase Functions, AWS SNS, or custom server solutions to manage notification delivery.

Implementation steps include: handling token registration and refresh, implementing notification listeners for foreground/background states, configuring notification appearance (title, body, icons, actions), and managing deep linking when users tap notifications.

Advanced features include notification categorization, rich media notifications (images, videos), notification scheduling, user segmentation, and A/B testing for notification content. Always implement proper error handling and respect user preferences for notification frequency and types.
