Description

https://issuetracker.google.com/issues/122953695#comment13 has some comments from Google on this. The .so files are not extracted to disk, so they don’t exist where RN is looking for them. This only occurs with .aab files (app bundles), not .apk files.

“Someone should probably file a bug with reactnative so they stop reading the .so from the install directory and instead read it from the APK or use the standard Android API to load so files.”

Reproducible Demo

Build an Android App Bundle (guide at https://developer.android.com/guide/app-bundle/) using Android Gradle Plugin 3.3 and try to load React Native - it will fail to find libreactnativejni.so

https://developer.android.com/studio/run/#reference has information on App Bundles.

Same issue. Getting couldn't find DSO to load: libreactnativejni.so with Android Gradle Plugin 3.3 and using Android App bundle. Even with RN 0.58 or 0.58.1, it doest not matter

IIRC, it was cherry-picked in 0.58.4.
