I run a simple iOS and Android WebView wrapper for my site. The site already fires browser-based push notifications, but those alerts don't work inside the apps. I want those same messages to arrive as native push notifications inside the app, and when a user taps the alert it should open the specific section of the app that matches the link. Here’s what I need: • Add the minimal native code needed on both platforms (Android Studio + Xcode) to register device tokens, receive pushes, and route the tap action to the relevant WebView path. • Re-use whichever service you feel is fastest to integrate—Firebase Cloud Messaging, OneSignal, or another—so long as it works reliably on both iOS (via APNs) and Android. • Provide a concise server-side example or cURL script that shows how I can forward my existing site notification payload to the new push service. • Hand me clean, well-commented source changes and a short README so I can rebuild and test on my own devices. Keep the scope lean: a functioning proof of concept that demonstrates one notification end-to-end is enough for this phase.
