    Ok I solved the issue by running the following command before building:

    curl "http://localhost:8081/index.android.bundle?platform=android" -o "android/app/src/main/assets/index.android.bundle"

    I guess you are looking for how to generate signed apk.

    it seem you did not have a react.gradle file under android/app: you can bundle the JavaScript package and drawable resources manually by doing the following in a terminal:

    $ mkdir -p android/app/src/main/assets
    $ react-native bundle --platform android --dev false --entry-file index.android.js \
      --bundle-output android/app/src/main/assets/index.android.bundle \
      --assets-dest android/app/src/main/res/
    $ cd android && ./gradlew assembleRelease
    

    after following this process app.release.apk will be under android\app\build\outputs\apk directory.
