Trouble with Android and the config plugin feature

[aciereszko]

Hi,

I've been looking to integrate this:

#5480

From @barthap into our app. It looks awesome, but I'm running into problems getting Crashlytics to run on Android. On iOS its fine.

Unless I'm missing something, it seems that the setup for Android differs from iOS only in the google-services.json file and its inclusion in the app.json file.

    "android": {
      "adaptiveIcon": {
        "foregroundImage": "./app/assets/adaptive-icon.png",
        "backgroundColor": "#FFFFFF"
      },
      "package": "...",
      "versionCode": 5,
      "googleServicesFile": "./android/google-services.json"
    }

The author mentions that the setup is the same as the with-rn-firebase plugin, which also mentions the addition of the installAndroid option, but that didn't do anything.

So while on iOS it all works, on Android I get this error:

[Fri Oct 15 2021 10:02:48.870]  LOG      Running "main" with {"rootTag":1}
[Fri Oct 15 2021 10:02:48.871]  ERROR    Error: No Firebase App '[DEFAULT]' has been created - call firebase.initializeApp()
[Fri Oct 15 2021 10:02:48.872]  ERROR    Invariant Violation: "main" has not been registered. This can happen if:
* Metro (the local dev server) is run from the wrong folder. Check if Metro is running, stop it and restart it in the current project.
* A module failed to load due to an error and `AppRegistry.registerComponent` wasn't called.

@barthap or anyone else maybe knows what I could be missing?

Thanks!

Andrzej

The configuration in app.json for the "official" plugin difers a bit from the one from the old with-rn-firebase plugin.

Have you included both @react-native-firebase/app and @react-native-firebase/crashlytics plugins into the plugins section of app.json as described here?

[barthap]

I see, but it wouldn't work in the expo app -> managed workflow right?

Right, Expo Go app doesn't support custom native code, it is mentioned in the docs. So you need to build a custom development client to be able to use RNFB in a managed-workflow way. Learn more here.

Btw. I wrote a tutorial on integrating RNFB + Expo Dev Client here.

Hey @barthap do you have a GitHub repository of the RNFB + Expo Dev Client tutorial ? I want to use RNFB database and Firestore but it does not seem to work. I don't really know what I am doing wrong.

[barthap]

No, but I'm considering updating my very old RNFB demo repo to use Dev Client

Edit: I updated my old CRUD repo and got it working with SDK 44, RNFB and Dev Client. You can find it here: barthap/ProductManagerDemo#18 - the code is available on the sdk44-dev-client branch. Not everything is updated yet (UI bugs, analytics had breaking changes meanwhile), but it should be mostly working as expected. The demo utilizes RNFB app, auth, firestore and analytics modules. Details can be found in the PR description or in readme (still partially outdated)

[barthap]

Ok, I updated the demo project to use Expo SDK 44, Dev Client and React Native Firebase (app, firestore, auth and analytics). It still has some minor issues, but thy're unrelated. The app works on both platforms as expected.

@barthap thank you!
