Mobile app – How to setup push notification with Firebase (1)?

Create Firebase project

• Download “google-services.json” file for Android
• Download “GoogleService-Info.plist” for iOS

Config iOS push notification

Create Apple Push Notifications service (APNs) key

Save & Download p8 key

Create Push Notification certificates for your app

Create “Certificate Request” file

Create Push Notification certificates

• Select your App Id

• Edit Push Notification

• Create Development and Production certificates
  • Upload the above request file

Upload Push Notification p8 file into Firebase

Remove old provisioning profiles and create new ones

This step is very important to let push notification work, if you still use old provisioning profile, push notification doesn’t work because the APNS certificate is strongly linked to the Apple Member account certificates/provisioning files. If they don’t match, the push won’t come through.

That means, you have to sign your app with the same provisioning file (with the same bundle id) you’ve signed the old app with.

Errors

If notification doesn’t come for iOS, try the following steps

• Remove “AppStore ID”, “Team ID”

• Delete your APNs certificate key

• Add .p8 back again, make sure Team ID is automatically generated from .p8 key
• Download “GoogleService-Info.plist” again
