Partnr - 16KB Migration
The Mission
Led the migration of a large-scale React Native application to support Android 15's 16KB memory page architecture by upgrading core Gradle settings, dependencies, and native C/C++ libraries, achieving successful Google Play Store validation.

Engineered Features
Building with precision and purpose
16KB Page-Size Migration
Updated native compiling flags and Gradle configurations to align memory mapping boundaries to 16KB pages.
Dependency Auditing
Resolved dependency conflicts by upgrading React Native, NDK, AGP, and native packages like Firebase and Reanimated.
Binary Alignment Tests
Used command-line binary tools (readelf/zipalign) to verify the output package alignment before production release.
🚗 Android 15 Memory Migration
Starting with Android 15, devices can enforce 16KB memory page boundaries instead of the traditional 4KB. Non-compliant apps with native C/C++ libraries fail to load or install. This engineering stream focuses on auditing, configuring, upgrading, and testing our large-scale React Native production codebase to ensure full compliance and seamless operation.
🎯 Engineering Challenges & Memory Limits
✨ Native Upgrades & Google Play Compliance
We systematically audited the app's native dependencies. We updated the compiler flags in CMakeLists.txt and build.gradle to enforce 16KB alignment, upgraded the React Native core, Firebase SDK, and configured Gradle settings. The output binary alignment was thoroughly tested using play console pre-launch reports and local check scripts, ensuring a 100% compliant, crash-free launch.
