Overview

We need an experienced Android/React Native developer to make our production app fully compliant with Google Play's 16 KB memory page size requirement for apps targeting Android 15+ (SDK 35).

Google Play Console has already flagged 19 non-compliant .so files in our latest production build. We have a full mapping of each library to its source package (provided below).

Our Stack

React Native with Expo SDK 52
Hermes JS engine (enabled)
AGP resolved via RN 0.76 version catalog)
Gradle 8.10.2, NDK

* targetSdkVersion 35, compileSdkVersion 35

CI/CD: Codemagic

Flagged Libraries (from Google Play Console)
Google Play has identified 19 .

so files across arm64-v8a and x86_64 that are not 16 KB page aligned:

React Native Core / Hermes (5 files):
* — Hermes JS engine
* — Hermes tooling
* — NDK C++ standard library
* — React Native core
* — JavaScript Interface (Meta)

Facebook/Meta — Fresco Image Pipeline (5 files):
* — Facebook JNI bindings
* — Fresco GIF support
* — Fresco image pipeline
* libstatic- — Fresco WebP support
* libnative- — Fresco image transcoder

Expo Modules (2 files):
* libexpo-modules- — expo-modules-core
* — expo-image 2.0.7

Third-Party npm Packages (7 files):
* / — react-native-reanimated 3.16.7
* — react-native-mmkv 2.12.2
* — react-native-quick-crypto 0.7.17
* — react-native-screens 4.10.0
* libanimation-decoder- — lottie-react-native 7.1.0
* libnative- — @shopify/flash-list 1.8.3

Scope of Work

Determine the fix strategy for each flagged library — Whether to upgrade the dependency, patch the native build, add linker flags (-Wl,-z,max-page-size=16384), or upgrade NDK/build tools.
Apply fixes — Upgrade packages, patch build configs, or apply whatever is needed to make all 19 .so files 16 KB aligned.
Verify alignment — Run zipalign -c -P 16 and/or Google's on the release AAB to confirm all .so files pass.
Test on 16 KB emulator — Set up an Android 15 emulator with 16 KB page size enabled, install the app, and verify it launches and runs without crashes.
Document changes — Provide a brief summary of what was upgraded/changed and any libraries that need upstream fixes or workarounds.

Deliverables

A release AAB that passes zipalign -c -P 16 with zero flagged libraries
All changes committed to a branch in our GitHub repo (we'll provide access)
A short written summary covering: What was changed per library

Any dependency upgrades performed
Any known risks or follow-up items

react-native-maps 1.18.4
react-native-fbsdk-next 13.4.1

Custom SDK (bundled locally)
Custom Adjoe SDK bundled locally)

Ideal Candidate

Can set up and test on Android 15 16 KB page size emulator images
