Summary:
This allows everyone to deploy significantly smaller APKs to they Play Store by building separate APKs for ARM, x86 architectures.
For a simple app, a release APK minified with Produard:
- Universal APK is **7MB**
- x86 APK is **4.6MB** (34% reduction)
- ARM APK is **3.7MB** (47% reduction)
Created a sample project, uncommented `// include "armeabi-v7a", 'x86'`:
cd android
./gradlew assembleDebug
Three APKs were created, unzipped each: one has only x86 binaries,
one has ARM binaries, one has both.
./gradlew assembleRelease
Three APKs were created, JS bundle is correcly added to assets.
react-native run-android
The correct APK is installed on the emulator and the app runs fine
(Gradle output: "Installing APK 'app-x86-debug.apk'").
With the line commented out the behavior is exactly the same as before,
only one universal APK is built.
Checked that version codes are set correctly as described in
