React Native 0.71.3 + Typescript. Project uses ProGuard too, apparently.

I'm trying to integrade push notifications through cloud messaging. I've only tested it on Android.

I did all the steps required. What am I missing?

npm install --save @react-native-firebase/app
placed my google-services.json file in /android/app/ folder
Added classpath 'com.google.gms:google-services:4.4.0' at /android/build.gradle
Added apply plugin: 'com.google.gms.google-services' at /android/app/build.gradle
npm install @react-native-firebase/messaging
npx react-native run-android to rebuild the project
7)import messaging from '@react-native-firebase/messaging';in my App.tsx
For testing, I'm adding this function from the documentation

async function requestUserPermission() {
 const authStatus = await messaging().requestPermission();
 const enabled =
 authStatus === messaging.AuthorizationStatus.AUTHORIZED ||
 authStatus === messaging.AuthorizationStatus.PROVISIONAL;
 if (enabled) {
 console.log('Authorization status:', authStatus);
 }
}

I call the function inside an useEffect() in App.tsx

Yet, despite all these steps, I keep getting

 Possible Unhandled Promise Rejection (id: 0):
Error: No Firebase App '[DEFAULT]' has been created - call firebase.initializeApp()

What am I missing? This is driving me insane.

Reproduced. On rn71 stock templates if you use google-services 4.4.0 it fails on android in exactly the way you describe

If you use rn71 you must use google-services 4.3.15 - it works fine
If you use rn72 you may update to google-services 4.4.0 - it works fine

I'll post a note in the install documentation

Thanks for noticing this!

Hey there 👋 - there must be some steps after step 9? Like "then I run the pod install / build for whatever platform etc" ? I'm not sure which platform the problem is on so I can't say what those commands should be but if you specify what you do I may be able to help more.

Alternatively you can have a quick read through the comments on my "build a firebase app from scratch, start to finish in one script" script where I demonstrate how to do the integration: https://github.com/mikehardy/rnfbdemo/blob/main/make-demo.sh

Hi. I'm having the same issue, which has also drove me insane, well almost. ;-). My findings so far:

In my case, the NATIVE_FIREBASE_APPS array of the RNFBAppModule Native Module seems to be empty on Android. On iOS, this array contains 1 element, which is a reference to the Firebase App on the native side. On Android, this array is filled in the getConstants method of the ReactNativeFirebaseAppModule (contained in the @react-native-firebase/app package).
To research the issue further, I have set up 2 basic React Native projects (using the npx react-native init command). One project uses RN version 0.71.13 and the other version 0.72.7. To both projects, I have added the latest @react-native-firebase/app package (18.6.1) and added the google services gradle plugin and the google services json file. On the 0.72.7 version, everything works as expected and on the 0.71.13 version the same error is seen.
The Google Services grade plugin should parse the google services json file and create 1 (or 2?) xml files (see android/app/build/generated/res/) that are then used at runtime to initialize the Firebase objects. In the 0.71.13 project, these files are not created while on the 0.72.7 version, these are correctly created.

I suspect that there is some version incompatibility issue between Gradle and the Google Services gradle plugin.

@sander48k very interesting finding. rn71 certainly worked when I was build-testing while it was out

At the time the google-services plugin version was 4.3.15 - have you tried that one in combination with react-native 0.71.x ?

I've branched my reproducible build-test repo at the commit where rn71 was last used (implying it uses google services plugin 4.3.15, not current / 4.4.0),

I'm running a build test now https://github.com/mikehardy/rnfbdemo/blob/rn71/make-demo.sh but may run out of time today before I can report more results.

It does seem that upgrading to react-native 0.72 is a obvious pathway to success here though :-)

Thanks Mike! Good to know that version 4.3.15 works with my rn71 project!

in my case, another problem was that i had missed the step 4 which @DragomirAndrei19 mentioned:
"Added apply plugin: 'com.google.gms.google-services' at /android/app/build.gradle"

(it's just one line in the documentation and i had missed it! took me a day to figure that out😑)

anyway I ended up using RN 0.72.6 and com.google.gms:google-services:4.4.0.

@zocial-rajesh --> does not reproduce: https://github.com/mikehardy/rnfbdemo/blob/main/make-demo.sh

You might examine the output of that from-scratch successful-build reproducer and see if you can find the difference in your gradle files, that should get you going

You need to configure crashlytics(or any other firebase services which u want) separately after configuring firebase https://rnfirebase.io/crashlytics/usage
There are some additional steps here.

Maybe you forgot to add the plugin in your app/build.gradle?

I'm using Expo and using typescript. In my case plugins were not working so I had to go with React Native CLI - Android Setup instead of Expo.

"react-native": "0.74.3"
"expo": "^51.0.21"
"@react-native-firebase/app": "^20.3.0"
"@react-native-firebase/messaging": "^20.3.0"

I'm using Expo and using typescript. In my case plugins were not working so I had to go with React Native CLI - Android Setup instead of Expo.

React Native CLI - Android Setup documentation for expo solved my issue

adding in app.json :

"plugins": [
"@react-native-firebase/app",
"@react-native-firebase/messaging"
]

solved the "call firebase.InitializeApp()" issue,

still didn't get the notification so i added the permission of expo-notifications and it's working now...

Adding the plugins to app.json worked (I'm running RN 0.74.5) but I also had to run npx expo prebuild --clean before it would add the com.google.gms:google-services:4.4.1 line to my build.gradle.

Double-check if apply plugin: 'com.google.gms.google-services' is added inside build.gradle located inside android/app folder

I resolved the issue by updating the package.json dependencies for Firebase:

"dependencies": {
 "@react-native-firebase/app": "^21.3.0",
 "@react-native-firebase/messaging": "^21.3.0"
}

I found the latest compatible versions on the npm website.

This solution worked for me! I had to update all my firebase dependencies and I'm using the following versions:

Tried to fix it with the following setup:

Dependencies Tried:
"react-native": "0.75.4",
"expo": "^51.0.31",
"@react-native-firebase/app": "^21.3.0" AND "^21.6.1"
"@react-native-firebase/messaging": "^21.3.0" AND "^21.6.1",

Different try:
"expo": "^52.0.11" with
"react-native": "0.76.3"

react-native failed to have compatibility for aws/amplify UI, so didn't get to check if it was working with Firebase.

So, you are on an old react-native, you likely need google-services gradle plugin 4.3.15, as indicated above @Muhammadmahadsaeed

What version of that plugin are you using?

@Muhammadmahadsaeed

Muhammadmahadsaeed Jul 8, 2025

@mikehardy i am using this classpath 'com.google.gms:google-services:4.4.2' and also tried with 4.3.15 but still facing same issue on android and ios

+ classpath 'com.google.gms:google-services:4.4.3'

I hope it will help someone
