Frequent Crashes in Android App (Audienzz Library v0.4.5, React Native 0.67.5)

[jlopezdominguez]

Hi,

We have recently observed that a significant number of crashes reported in Firebase Crashlytics for our app are related to the Audienzz library.

Library Version: We are currently using version 0.4.5 of the Audienzz library with React Native version 0.67.5.
Platform Affected: The issue appears to be isolated to our Android application.
Crash Details: Below are the three main types of crashes we have encountered over the last month regarding the Audienzz library:

1. AdView.java line 115 (com.appnexus.opensdk.AdView)

Any tips on how could we solve this ?

Thanks

Hi,

After upgrading React Native from 0.67.5 to 0.72.12, we're still encountering the same Crashlytics reports.

Additionally, we have observed this crash in another app that uses version 0.5.5 of this library(running React Native 0.67.5, the RN 0.72.12 upgrade hasn't been published yet).

Could you provide any updates or clues on when these bugs might be resolved?

Thank you.
