About this gig

Is your React Native Android app crashing on new devices? Getting Play Store rejection due to 16kb page size alignment? App running slow or consuming too much memory? I can fix all of that.


What I Fix & Optimize

  • Android 16KB memory page size alignment (required for Android 15+ / Google Play 2025 compliance)
  • NDK native library alignment issues
  • Gradle & build.gradle configuration updates
  • React Native version upgrades (0.70 0.73/0.74)
  • Performance bottlenecks (slow renders, janky animations)
  • Memory leaks and excessive RAM usage
  • Bundle size reduction with Metro bundler optimization
  • ProGuard / R8 minification setup
  • Crash fixes and error handling improvements
  • Play Store compliance and submission issues


Why This Matters

Google Play now requires all new apps and updates to support 16KB page size alignment for Android 15+ devices. Without this fix, your app will CRASH on the latest Android hardware including Samsung Galaxy S25 series.
