[Salakar]

@Rewieer could you provide us the full error + stack trace - so we can see where exactly the error is occurring, thanks

[rewieer]

Solved the issue by removing xmlns:tools="http://schemas.android.com/tools" and tools:node="replace" from my AndroidManifest.xml, thanks you !

See this for more information

[StepanNaryshkov]

I have the same problem on ios (

[toblerpwn]

^ Ditto on iOS.

[felipap]

Try rolling back to 3.2.0 for now.

[theohdv]

@Salakar @Rewieer can it be reopened? Seems to be not fixed (iOS & Android).

React-native: 0.52.2
React-native-firebase: 3.2.0

[rewieer]

I've reopened it.

[chrisbianca]

@StepanNaryshkov @toblerpwn @theohdv It sounds like your iOS project doesn't have the .plist file linked correctly - that's the only reason why the default project wouldn't be initialised.

Have you updated your version of React Native recently? If so, I'd check that you haven't overridden the linking to the .plist file.

[theohdv]

Yes it was linked to the recent update of react native in my project. Fixed now.

React-native 0.52.2
react-native-firebase 3.2.0

[chrisbianca]

Ok, in which case I'm going to close this issue again.

[Kottidev]

@theohdv when i remove tools:node="replace"

I got this error
`* What went wrong:
Execution failed for task ':app:processDebugManifest'.

Manifest merger failed : Attribute meta-data#android.support.VERSION@value value=(26.0.1) from [com.android.support:exifinterface:26.0.1] AndroidManifest.xml:25:13-35
is also present at [com.android.support:appcompat-v7:26.1.0] AndroidManifest.xml:28:13-35 value=(26.1.0).
Suggestion: add 'tools:replace="android:value"' to element at AndroidManifest.xml:23:9-25:38 to override.

`

[theohdv]

I didn't have to remove anything and it works (be sure to remove and reinstall npm package, link native package, remove cache ...). Ask @Rewieer, about this hack.

[Kottidev]

@Rewieer

How can i fix this issue ,

with react-native-camera i can't remove tools:node="replace"

and if this line exist in AndroidManifest i have this error
The [[DEFAULT]] firebase app has not been initialized!

[rewieer]

@Kottidev to be honest idk anymore, I ditched RNC out of my project because it wasn't working on Honor phones and made my own implementation.
But I believe this is a dependency error. See #48 and try to see various settings. As far as I remember I think it was something to do with the vision API (a dependency of the new RNC)

[benevbright]

Although 'wanted version' of react-native is 0.51, it happens to me on 0.51. (iOS)
I updated RN to 0.53 and problem is resolved. (iOS)

[noahtallen]

I resolved this issue by downloading a new version of google-services.json (some changes had been made to the bundle identifier that needed to match up with google) and was the key: a dev had commented out apply plugin: 'com.google.gms.google-services' from the end of app/build.gradle for debugging. Uncommenting that got it working again.

[heckchuckman]

@ntomallen I can confirm that downloading a new version of GoogleService-Info.plist, replacing the file in your ios directory, and rebuilding does the trick on iOS, as well.

Thanks!

[e11i0t]

I had the same issue for ios, my mistake was I forgot a step during the installation:

B) At the beginning of the didFinishLaunchingWithOptions:(NSDictionary *)launchOptions method add the following line:
[FIRApp configure];

[noahtallen]

When you come to an issue trying to find help, but you realize you already had the same problem a month ago on a different platform

[apoterenko]

Yeah, @Kottidev is right. I have the same issue right now. I am using RNC (camera) & RNF together at the same time.

xmlns:tools="http://schemas.android.com/tools" and tools:node="replace"
=>
The [[DEFAULT]] firebase app has not been initialized!

Damn it! I have spent ~6 hours to understand the source of a problem.

[dannysood]

@apoterenko how did you fix the issue?

I/FirebaseInitProvider: FirebaseApp initialization unsuccessful

Okey So i figured out the problem

apply plugin: "com.google.gms.google-services"

was missing in build.gradle
It was a silly mistake from my part

[derekbar90]

I've gone through these steps and possible solutions relentlessly but still am finding myself with this issue.

1. I'm calling apply plugin, it's grabbing the correct config file, it's also parsing the file correctly.
2. If I initialize myself I can get an object for the firebase initialized app but nothing comes over the wire to the firebase console etc. Although, the obj will say its native initialized.
3. firebase.analytics.nativeModuleExists returns true

[derekbar90]

After digging deeper it looks like this line is the culprit

List firebaseAppList = FirebaseApp.getApps(getReactApplicationContext());

from RNFirebaseModule.java

Currently for me it only returns zero

[felipap]

@derekbar90 Did you ever find a solution?

[nguyenngoi]

I have a same error:

I use:
"react-native": "^0.55.4",
"react-native-firebase": "^4.2.0",

any solution?

[motogod]

I have the same issue like @nguyenngoi , i find the document https://github.com/invertase/react-native-firebase-docs/blob/master/docs/core/initialize-apps.md

My test platform is Android.

My androidConfig clientId and appId i copy them from google-services.json. And the other arguments just copy them from Firebase console in Javascript project.

Finally it can be initialized from the code:

const firebaseApp = firebase.initializeApp(
  Platform.OS === 'ios' ? iosConfig : androidConfig,
  'test_fire'
);

I test it on email auth successfully.

But I still has a problem in my terminal message shows Deprecation: Calling 'initializeApp()' for apps that are already initialised natively is unnecessary, use 'firebase.app()' instead to access the already initialized default app instance.

I try to use the code it will show error Firebase has not been initialized

import firebase from 'react-native-firebase';
const firebaseApp = firebase.app('test_fire'); 

Any one has solution ?

[johnlk]

I was able to solve this error of my own on iOS by including this line in the AppDelegate.m at the top of the launchOptions method:

[FIRApp configure];

[devsimple-luckyteo]

@johnlk thank you, I had the same issue for ios.
Your solution work for me.

[MelihOzyurt]

I had the same issue for ios, my mistake was I forgot a step during the installation:

B) At the beginning of the didFinishLaunchingWithOptions:(NSDictionary *)launchOptions method add the following line:
[FIRApp configure];

`#import "AppDelegate.h"

import

import

import

@implementation AppDelegate

• (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
  {
  [FIRApp configure];

  NSURL *jsCodeLocation;

  jsCodeLocation = [[RCTBundleURLProvider sharedSettings] jsBundleURLForBundleRoot:@"index" fallbackResource:nil];

  RCTRootView *rootView = [[RCTRootView alloc] initWithBundleURL:jsCodeLocation
  moduleName:@"ykstyt"
  initialProperties:nil
  launchOptions:launchOptions];
  rootView.backgroundColor = [[UIColor alloc] initWithRed:1.0f green:1.0f blue:1.0f alpha:1];

  self.window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds];
  UIViewController *rootViewController = [UIViewController new];
  rootViewController.view = rootView;
  self.window.rootViewController = rootViewController;
  [self.window makeKeyAndVisible];
  return YES;
  }

@end
`

AppDelegate.m file in this way but not working!

React-native run-ios after "Build successful" but xCode in Thread1: 'Signal SIGABRT' error?

[rezareact]

Link your library again && Delete duplicated lines in build.gradle and main java && check installation document exactly && re run your project
this solved my same issue

[dylan-dinh]

Hello,

I actually have the same issues but only when I call this when I try to determine if an user is already logged in or not :
firebase.auth().onAuthStateChanged(user => { this.props.navigation.navigate(user ? 'Main' : 'SignUp') })

This is called inside the following function which is the first function of my class in the entry point file :
componentDidMount() { }

Here the error message in case of :
Error : The [[DEFAULT]] firebase app has not been initialized
with some more log about where is it located : in Loading / SceneView / SwitchView / in Navigator

And when I comment this very line, no more error about this.

Should I use :

const firebaseApp = firebase.initializeApp(
Platform.OS === 'ios' ? iosConfig : androidConfig,
'test_fire'
);
And if yes in which file ? Index or first entry point file (most likely App.js) ?

thanks in advance

[anhdevit]

You miss file GoogleService-Info.plist in project
Just add it

[keiranvv]

@rewieer

How can i fix this issue ,

with react-native-camera i can't remove tools:node="replace"

and if this line exist in AndroidManifest i have this error
The [[DEFAULT]] firebase app has not been initialized!

For anyone else in this situation, I managed to resolve the issue by changing tools:node="replace" to tools:replace="android:allowBackup".

This did not cause any issues with react-native-camera

[jahglow]

Heads up: This error is raised in Android with classpath 'com.android.tools.build:gradle:3.3.0', last working version is classpath 'com.android.tools.build:gradle:3.2.1', affects versions 5.1.x, 5.2.x/ Please reopen!

[ollydixon]

Newer version of Android studio 3.3.1 requires a higher version of Gradle plugin that no longer supports react-native-firebase it seems (And some other libraries). I'm seeing this error on a dummy project following the instructions and the steps/fixes here. Any ideas?

[bemnet4u]

I downgraded to 'com.android.tools.build:gradle:3.3.0' and it still doesn't work. I get this error.

@voidstarfire Do you really need to downgrade android studio too? Where you able to find a workaround for this?

OK i resolved my issue by using the firebase/android studio integration to sync my google-service.json file and add admob to my build.gradle files

[NomanGul]

Thanks @Debarshi-Banerjee

[iamswain25]

incompatible with RN 0.59 gradle 3.3.1, please reopen!

[otaviosoares]

@iamswain25 I got it working on RN 0.59 by upgrading com.google.gms:google-services to 4.2.0.

[Fsarmento]

@otaviosoares by upgrading com.google.gms:google-services to 4.1.0 to 4.2.0 I start getting another error... damn this is hard.

ERROR: In project 'app' a resolved Google Play services library dependency depends on another at an exact version (e.g. "[1.3.1

Dependency failing: com.nimbusds:nimbus-jose-jwt:5.1 -> net.minidev:json-smart@[1.3.1,2.3], but json-smart version was 2
.3.

The following dependencies are project dependencies that are direct or have transitive dependencies that lead to the art
ifact with the issue.

-- Project 'app' depends on project 'react' which depends onto com.nimbusds:[email protected]

For extended debugging info execute Gradle from the command line with ./gradlew --info :app:assembleDebug to see the dep
endency paths to the artifact. This error message came from the google-services Gradle plugin, report issues at https://
github.com/google/play-services-plugins and disable by adding "googleServices { disableVersionCheck = false }" to your b
uild.gradle file.

[otaviosoares]

@Fsarmento Do you have code-push installed?

I had the same problem. Check https://github.com/Microsoft/react-native-code-push/issues/1448

[mikehardy]

Fascinating @otaviosoares - @Fsarmento looks like you have to disable strict version checking until an upstream bug is fixed https://github.com/Microsoft/react-native-code-push/issues/1448#issuecomment-469902328

[fariswd]

after initialize on AppDelegate.m don't forget download and copy google-info.plist to ios/appName

[Ethan0007]

Hi Guy,

I'm following your instructions but i have an issue when install the app, it will crash without any reason here is my config and deps:

"react-native-firebase": "^5.3.1",

[brave-merida]

@Ethan0007 , Did you start the react native metro bundler?
Please use react-native start command on your project root directory.
After it's done, restart your app.

Did you find solution for this?!

[lunatolun]

Make sure
apply plugin: 'com.google.gms.google-services'

goes to the bottom of android/app/build.gradle, not android/build.gradle

[mikehardy]

This issue no longer is focused on any particular problem. For future searchers, if you see this it is always an install error of some sort

We see these so often I created a script that goes from zero to a working firebase app on android and ios. Do what it does and your install should work, or at the very least you'll know it's not react-native-firebase:
