React-native-firebase: java.lang.NoClassDefFoundError: at ly.b (com.google.android.gms.policy_ads_ for Android 9.0 Pie Users

[sagarv1997]

Issue

I have recently integrated the Firebase Admob in my application and released the update on the Google Play store, but found many crash reports from the Android 9 Users.

Here is stack trace from Google Play store

I pasted your error into duckduckgo search and got this. Have you tried the accepted answer?
https://stackoverflow.com/questions/55598500/why-does-my-app-crashes-with-admob-and-firebase

[mikehardy]

(if it works we may need a doc update, even if this is not really a react-native-firebase problem)

[mikehardy]

Indeed, this is confirmed by official support. You must enable legacy http library

It's an upstream SDK issue, not an issue with this module

Thanks for the update, I have tried and released the App, hope it fixes the issues, I'll report here if it fixes, do update docs if it fixes :)

[mikehardy]

PR would be here I think if it works https://github.com/invertase/react-native-firebase-docs/blob/v5.x.x/docs/admob/android.md

Thanks, it worked, have not seen any crash log in the past 12 hours!
Have created a PR for docs update :)
