To Reproduce

Create a new project with react-native init and then generate a signed APK using this.

Expected Behavior

~8mb APK size.

This is because of JavaScript Core update. Just change:
def enableSeparateBuildPerCPUArchitecture = false to def enableSeparateBuildPerCPUArchitecture = true in your android/app/build.gradle so APK file will be splitted per architecture resulting in smaller APK files that all should be updated to Google Play and Store will automatically pick up the correct version for user.
