[android] No Firebase app '[DEFAULT]' has been created - call firebase.initializeApp(), js engine: hermes

[francisleigh]

most setup issues such as default app has not been initialized etc are all down to an incorrect setup as the guides haven't been correctly followed.
^ I am pretty certain i've gone through the correct setup.

Issue

During my upgrade migration to RN 0.61.2 from 0.59.10 i had to upgrade a few dependancies - RNFB being one of them.

IOS is building fine.

Android builds fine but then i am greeted with an error.

I have one file that calls/uses firebase.

Analytics.js

import analytics from "@react-native-firebase/analytics";
const FirebaseAnalytics = analytics();

const FirebaseAnalytics = analytics(); is what triggers my error.

android/settings.gradle

include ':@react-native-firebase_messaging'
project(':@react-native-firebase_messaging').projectDir = new File(rootProject.projectDir, '../node_modules/@react-native-firebase/messaging/android')
include ':@react-native-firebase_in-app-messaging'
project(':@react-native-firebase_in-app-messaging').projectDir = new File(rootProject.projectDir, '../node_modules/@react-native-firebase/in-app-messaging/android')
include ':@react-native-firebase_analytics'
project(':@react-native-firebase_analytics').projectDir = new File(rootProject.projectDir, '../node_modules/@react-native-firebase/analytics/android')
include ':@react-native-firebase_app'
project(':@react-native-firebase_app').projectDir = new File(rootProject.projectDir, '../node_modules/@react-native-firebase/app/android')

include ':app'

android/app/build.gradle

...
dependencies {
    implementation project(':@react-native-firebase_messaging')
    implementation project(':@react-native-firebase_in-app-messaging')
    implementation project(':@react-native-firebase_analytics')
    implementation project(':@react-native-firebase_app')
    ...
}
...

I tried adding

implementation "com.google.firebase:firebase-analytics:17.2.0"
implementation "com.google.firebase:firebase-messaging:20.0.0"
implementation "com.google.firebase:firebase-inappmessaging:19.0.1"

to the dependancies Object but no-dice.

I don't think hermes is working correctly with RNFB, as a side note

I think you're missing this part from RN59 to RN60 move https://github.com/facebook/react-native/blob/master/template/android/settings.gradle

Mike, thank you again!

Changes i also made

android/build.gradle

dependencies {
    classpath("com.android.tools.build:gradle:3.4.0")
+   classpath("com.google.gms:google-services:4.2.0")
    ...
}

[mikehardy]

I think they are on 4.3.2 now :-), gradle/android studio is on 3.5.1

nothing like keeping track of 4 ecosystems (ios / android / react-native / firebase) at once right?

[aravi365]

i am having the same issue with ios build. Any idea what caused it??

[francisleigh]

@aravi365 i never experienced this on IOS. have you done a fresh pod install?
when i'm in doubt i run these series of commands from the root of my project.

$ rm -rf node_modules && cd ./ios && rm -rf Pods/ && cd ../ && npm i && cd ./ios && pod install && cd ../android && ./gradlew clean && cd ../ && npx jetifier

What the above does is:

1. removes node_modules
2. removes Pods/
3. installs node_modules
4. installs pods
5. cleans the gradle
6. uses Jetifier to port over AndroidX dependancies.

But, the solution you've given mainly points out to android related. My android is working fine without any issues.
What ended up in this situation is -- i created a separate project with the same project name as i have skipped the ios upgrade part while upgrading.

[francisleigh]

@aravi365 Sorry, that wasn't a solution it was more of a process i take before i go looking for an answer just to make sure my project has not got anything weird and quirky going on within it.

If you skipped the IOS related parts of your upgrade, during the upgrade then i'd go back with a fine-toothed comb and check incase theres anything lurking within the code that you are missing.

[mikehardy]

npx react-native-clean-project clean-project-auto

99 percent of the time it works every time haha

[mikehardy]

There is an obvious spelling error there since I was on mobile, sorry, fixed.

[1fabiopereira]

I spent a lot of hours for found who was the problem, I fixed that adding apply plugin: 'com.google.gms.google-services' at the bottom of android/app/build.gradle. I don't kwow if that is the best approat but solve the issue.

[mikehardy]

@1fabiopereira not only the best approach, but the documented method of integrating https://invertase.io/oss/react-native-firebase/quick-start/android-firebase-credentials#applying-the-config-file

https://github.com/mikehardy/rnfbdemo/blob/master/make-demo.sh#L37

This is a very tough module to set up correctly because it's really like 15 big modules in one. Using the docs is vital for success

[tomthornton]

@mikehardy I tried this, but then I get this error

Execution failed for task ':app:processDebugGoogleServices'
No matching client found for package name 'com.[appname]'

This stackoverflow answer has you delete that line, which causes the error again :/
