Issue: Unable to get provider io.invertase.firebase.crashlytics.ReactNativeFirebaseCrashlyticsInitProvider

[rahulkasana]

Hello, I've been using
"react-native": "0.61.5",
"@react-native-firebase/app": "^6.3.4",
"@react-native-firebase/crashlytics": "^6.3.4"

I recently uploaded the app on playstore and when playstore ran pre launch reports the app is crashing only for Galaxy S3 running at Android 4.3
It's working on 11 devices but failing on just 1 device.

This is the error -
FATAL EXCEPTION: main

So is it an issue OR Android 4.x is not supported by Firebase v6?

[mikehardy]

Smells like a multidex issue somehow if it's down on the Android 4.x devices. It should work fine on those though - assuming multidex is set up correctly. t†https://github.com/mikehardy/rnfbdemo/blob/master/make-demo-v6.sh#L125

Thanks @mikehardy that solved the issue!

Hey @mikehardy, I got stuck into the same issue and was unable to access the link which you shared - Can you please reshare the fix for the multidex

[mikehardy]

There is no need for multidex, no version of Android still supported needs it. It is no longer a needed solution in any supported cases I'm aware of

[RahulMJ5]

Oh, Anyway I keep getting this below error on the logcat after the app crash,
The temporary solution is to clean the Gradle and re-run the app.
Let me know If you have a better Solution
