[Android] [expo-notifications] Exception occurred while executing exported method getDevicePushTokenAsync on module ExpoPushTokenManager: Default FirebaseApp is not initialized in this process

Push notifications on Android aren’t working. I’ve followed all the steps.

I initialize the firebase app:

import { FirebaseOptions, initializeApp } from ‘firebase/app’
import googleServicesConfig from ‘./google-services.json’

const firebaseConfig: FirebaseOptions = {
apiKey: googleServicesConfig.client[0].api_key[0].current_key,
// authDomain: ‘project-id.firebaseapp.com’,
projectId: googleServicesConfig.project_info.project_id,
// storageBucket: ‘project-id.appspot.com’,
messagingSenderId: ‘REMOVED’,
appId: googleServicesConfig.client[0].client_info.mobilesdk_app_id,
// measurementId: ‘G-measurement-id’,

export const firebaseApp = initializeApp(firebaseConfig)
console.log(‘Initialized Firebase app’, firebaseApp)
And the following works on iOS, but not on Android:

await Notifications.setNotificationChannelAsync(‘default’, {
name: ‘default’,
importance: Notifications.AndroidImportance.MAX,
vibrationPattern: [0, 250, 250, 250],
lightColor: COLORS.primary[500],

let permissions = await Notifications.getPermissionsAsync()
let finalStatus = permissions.status
console.log(‘Received notification permissions’, permissions)
if (finalStatus !== ‘granted’) {
console.log(‘Requesting notification permissions’)
permissions = await Notifications.requestPermissionsAsync()
finalStatus = permissions.status
console.log(‘Finished requesting permissions’, permissions)
if (finalStatus !== ‘granted’) {
console.log(‘Failed to get push token for push notification’, permissions)
return null

let token
try {
token = (
await Notifications.getExpoPushTokenAsync({
experienceId: ‘REMOVED’,
} catch (err) {
console.error(‘Error getting Expo push token’)
return null

console.log(‘Received Expo push token %s’, token, { permissions })

return token
Here’s the full error:

ExceptionsManager.js:151 Error: Encountered an exception while calling native method: Exception occurred while executing exported method getDevicePushTokenAsync on module ExpoPushTokenManager: Default FirebaseApp is not initialized in this process com.myapp. Make sure to call FirebaseApp.initializeApp(Context) first.

Expo Workflow: bare

Minimal reproducible example
Set up an Expo v47 bare Android app with firebase and notifications and attempt running the code above.

Create Firebase app with same package id (eg. com.myapp)
