Answer 1

In your root project directory

Make sure if you have already directory android/app/src/main/assets/ if not there create directory after that create new file and save as index.android.bundle and put your file in like this android/app/src/main/assets/index.android.bundle

After run this in cmd

react-native bundle --platform android --dev false --entry-file index.js --bundle-output android/app/src/main/assets/index.android.bundle --assets-dest android/app/src/main/res/

cd android && ./gradlew assembleDebug

then you can get apk app/build/outputs/apk/debug/app-debug.apk

The problem here is that you do not seem to have the entry file you have specified for react native bundle:

index.android.js

Replace it with your project's entry file index.js or app.js according to your project structure.

Update:

react-native bundle --dev false --platform android --entry-file <your-entry-file> --bundle-output ./android/app/build/intermediates/assets/debug/index.android.bundle --assets-dest ./android/app/build/intermediates/res/merged/debug

Create debug build:

cd android && ./gradlew assembleDebug

Your apk will be at android/app/build/outputs/apk
