Expo Notifications with EAS | Complete Guide

Firebase killed the legacy FCM API, so if your Android push notifications rely on the old setup, they're broken. This is the fix: FCM v1 credentials configured through EAS, tested on real Android and iOS devices. I go through the entire flow in the video, from creating the Firebase project to sending a test notification with expo.dev/notifications.

One warning up front: the service account key can't be recovered if you lose it, so treat it carefully.

What's inside

• Generate a Firebase service account key for FCM v1
• Upload it to EAS with eas credentials
• Fix invalid package names and bundle identifiers in app.json
• Trigger an Android build and generate a keystore with EAS CLI
• Send test pushes with custom title, body, badge, and sound
• Verify credentials and builds from the Expo dashboard
