React-native-firebase: Crashlytics - unable to trigger forced crash on Android

[iGoogledYouYesterday]

Issue

I am trying to implement Crashlytics to my React Native project, but for some reason my crashes are not reported in Firebase.

One thing to mention also is that Im using Analytics package without any issues - they all get reported - and I have DEBUGVIEW enabled which gives me instant logging of events.

Im importing and executing force crash code in one of my main components on component will mount.

import crashlytics from '@react-native-firebase/crashlytics';

UNSAFE_componentWillMount() {
crashlytics().log('Testing crash');
crashlytics().crash();
analytics().setCurrentScreen("Home", "Home");

}

Crashes can take a good while to come through. How long have you been waiting?

[iGoogledYouYesterday]

Tested it last night - like 12 hours ago - still no crashes shown.
Then tried testing it this morning.
Disabling Debugging in the emulator didnt help.

Dashboard shows:
Crash-free users - 100%

firebase crashlytics does not work in debug mode check it in release mode will work like a charm.
you can check it by using
firebase.crashlytics().crash()
thanks

There are other reasons as well. Please review this comment and the next one: https://github.com/invertase/react-native-firebase/issues/2534#issuecomment-530954622

I think this could be in the API documentation for the crash function itself, it comes up pretty frequently and the reasons for not showing are many. @iGoogledYouYesterday if the information here and in the linked comment help you, can you please please :pray: hit the "edit" button at the top right of the documentation page and maybe add a quick "what if my crash doesn't show up?" section with bullet points?

@reactexcel you just saved my week, we've been stuck with this for way too long 🤦‍♂

[iGoogledYouYesterday]

@reactexcel -> Thank you very much! This helped me A LOT. I could have been trying till the dawn.

In deed - once I did

cd android && ./gradlew bundleRelease

and then run it with

react-native run-android --variant=release

It started showing errors in the Crashlytics.

Maybe the idea would be to highlight this instruction in the Docs for Crashlytics.
