App Crashed upon launch due to missing libhermes.so

[santhoshgutta]

The app crashed upon launch due to missing libhermes.co JNI library. This occurred when the container was migrated to use RN v0.60.5.

The app works fine in emulators, but not in devices. Also occurs in release version only.

The app crash was fixed by adding hermes-release.aar in app/libs folder, and libfb.so file in jniLibs\arm64-v8a, jniLibs\armeabi-v7a, jniLibs\x86, jniLibs\x86_64

I was able to find hermes-release.aar from node_modules⁩\⁨hermes-engine⁩\android⁩
