I will fix onesignal firebase push notification in your webview android app ios app fix
About this Gig
Push notifications not reaching users quietly kills engagement and revenue. If your Android, iOS, Flutter, or WebView app (WebViewGold, Median, GoNative, WebToNative, custom builds) has broken OneSignal or Firebase integration, missing player IDs, silent registration failures, or notifications that never arrive, I fix the root cause instead of patching symptoms.
I diagnose and repair push pipelines end to end:
- Exposing the OneSignal Player ID from a WebView shell
- Wiring the JavaScript bridge correctly
- Setting OneSignal.login with external_id for cleaner server side targeting
- Configuring Firebase Cloud Messaging from scratch
- Validating the full registration and delivery flow on real devices, not simulators.
Whether hybrid WebView, native Java/Kotlin Android, Swift iOS, or Flutter, I review your existing setup first so you are never charged for guesswork. You get a stable, tested pipeline, clear notes on what changed, and a fix that holds up after the next OS update.
Message me your setup and what's breaking, and I will tell you exactly what it takes to get users receiving notifications reliably again.

FAQ
Do you work with WebView based apps (WebViewGold, Median, GoNative)?
Yes, that's a core specialty, including exposing the Player ID through URL params or a JS bridge.
Do I need to give you source code access?
Yes, or repo access, so I can review the exact setup before quoting final scope.
Can you fix both Android and iOS?
Yes, each platform is scoped separately based on what's broken.
What if my app doesn't have Firebase set up yet?
I'll configure it from scratch as part of the fix.
Do you support Flutter and React Native, not just native apps?
Yes, all three plus native Java/Kotlin and Swift.
Will notifications work when the app is closed?
Yes, that's the standard I test for, not just foreground delivery.
What causes players IDs to go missing in WebView apps?
WebViews can't run service workers, so native OS level bridging is required.
Do you use OneSignal.login with external_id?
Yes, it's the cleanest long term fix versus URL params.
What do you need from me to start?
Your app source/repo, OneSignal and Firebase dashboard access, and a description of the symptom.
What if the issue turns out to be bigger than expected?
I'll flag it before doing extra work, no surprise charges.
