React-native-firebase: RNFirebase core module was not found natively on Android after Expo eject & detach

[QQizi]

Issue

I created an app using create-react-native-app
I detached & ejected Expo so i can now use native module for both IOS & Android.
I installed react-native-firebase perfectly on IOS but i happen to have this issue for Android.

I followed every instruction more than once but can't make it work.

Here are my gradles :

/android/build.gradle

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {

The only difference is that in /android/app/src/main/java there is no folder with the name of my project but this folder structure created by Expo

i have the same issue i am trying since 4 hours to solve it, but it dose not work.

[QQizi]

@moddatherrashed Did you detached & ejected Expo aswell ? And is it working fine on IOS ?

[moddatherrashed]

@QQizi no i had an Expo project, and to show the android and iOS folders i did run (exp detach), it is kind of the same but i did it the opposite way.
and i did not try it yet on iOS.
i am struggling man !

[moddatherrashed]

@QQizi try react-native link ! what it gives you ?

[QQizi]

@moddatherrashed I did use react-native link with no success

[moddatherrashed]

@QQizi i need to give it by the end of this week ! shit !

[Salakar]

Make sure to add the package to your MainApplication.java file?

https://github.com/invertase/react-native-firebase/blob/master/tests/android/app/src/main/java/com/testing/MainApplication.java#L12

and

https://github.com/invertase/react-native-firebase/blob/master/tests/android/app/src/main/java/com/testing/MainApplication.java#L45

as an example of how it should look.

[QQizi]

@Salakar Already did. I updated my first post with MainApplication.java

[Salakar]

Are you able to debug here:

https://github.com/invertase/react-native-firebase/blob/master/src/modules/core/firebase.js#L131

What is the value of NativeModules here: https://github.com/invertase/react-native-firebase/blob/master/src/modules/core/firebase.js#L4

[moddatherrashed]

@Salakar where should we find firebase.js script ?

[Salakar]

node_modules/react-native-firebase/dist/modules/core/firebase.js

[QQizi]

@Salakar

I'm able to debug in L131 & NativeModules looks fine

[moddatherrashed]

@Salakar here is the debug result --> RNFirebase core module was not found natively on Android, ensure you have correctly added the RNFirebase and Firebase gradle dependencies to your android/app/build.gradle file.

and the nativeModules seems to be fine

[Salakar]

Can you expand the output of NativeModules on the console there please, not showing the full log - you can do console.log(Object.keys(NativeModules));

[Salakar]

I don't think you're adding the native modules to the right place on Android code otherwise they'd be showing in that list of NativeModules.

cc @EvanBacon - could you point us in the right direction of where extra native modules can be added in ExpoKit.

[QQizi]

@Salakar Don't you think it can come from this point i explained in my first message :
The only difference is that in /android/app/src/main/java there is no folder with the name of my project but this folder structure created by Expo

Maybe the path where the app is trying to get some module doesn't works ?

[QQizi]

Well, for the third time in a row, i drop Expo after a few days of dev. Maybe one day this framework will be stable enough to actually be used.

[moddatherrashed]

@QQizi I did the same, no chance to make it work except that !

[EvanBacon]

Pretty close to landing the beta version of expo-firebase.

[Salakar]

Will close as this is not an issue with this library, please consult the expo documentation on how and where to integrate custom native modules as this isn't the right place for it.

Thanks
