Issue: Android app crashes on launch with dlopen failed: library "libreact_featureflagsjni.so" not found after migrating for 16 KB page size with React Native 0.77.0

Context

I am upgrading my React Native app from version 0.72.8 to 0.77.0 and trying to make the native .so libraries compatible with the Android 16 KB page size. The build is successful, but the app crashes immediately on launch with the following error:

Process: com.example.app, PID: 8267 java.lang.UnsatisfiedLinkError: dlopen failed: library "libreact_featureflagsjni.so" not found

Environment

  • React Native version: 0.77.0

  • Gradle version: 8.10 (distributionUrl: https://services.gradle.org/distributions/gradle-8.10-all.zip)

  • NDK version: 28.2.13676358

  • compileSdkVersion and targetSdkVersion: 35 (Android 14 / API 35)

  • newArchEnabled=false in gradle.properties (build fails otherwise due to Onfido SDK issue)

  • ABI filters: armeabi-v7a, arm64-v8a, x86, x86_64

  • Prefab enabled for native dependencies

  • Hermes enabled conditionally

  • Various libraries upgraded to match RN 0.77.0 compatibility

What I tried

  • Set newArchEnabled=false due to build failure caused by apply plugin: "com.facebook.react" inside @onfido/react-native-sdk/android/build.gradle.

  • Upgraded React Native to 0.77.0 and aligned libraries accordingly.

  • Enabled prefab true in buildFeatures.

  • Applied packagingOptions picks and excludes.

  • Verified native .so libraries built for 16 KB page size.

  • Verified Gradle and NDK versions.

  • ABI split enabled with versionCode overrides.

Problem

  • Build passes, but app crashes at launch with missing libreact_featureflagsjni.so.

  • Native libraries still seem incompatible with 16 KB page size on Android 14+.

  • Unable to load React Native native libraries causing crash.
