This project involves integrating OneSignal Push Notifications into our Android WebView application to enable real-time communication with users. The setup allows the app to receive and display instant push notifications sent from the OneSignal dashboard or server-side APIs, even when the app is running in the background or closed. The integration ensures seamless user engagement by delivering important updates such as announcements, alerts, reminders, and promotional messages directly to users’ devices. The WebView app should be properly configured with Firebase Cloud Messaging (FCM) and OneSignal SDK to handle notification delivery, click actions, and deep linking to specific web pages within the app. The solution is lightweight, scalable, and reliable, improving user retention and interaction without affecting app performance. It also supports audience segmentation, scheduling, and analytics through OneSignal’s dashboard for effective notification management.
