unable to load script from assets in

Answer 1

For all of you guys who are developing from a create-react-native-app and ejected, and have this issue in development, this is what worked for me just a little detail from the accepted answer

(in project directory) mkdir android/app/src/main/assets

here comes the part that changes cos you are in development get rid of the --dev: false part:

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

after that close all terminals, erase the build folder from android/app/ to make sure you start clean to build your app, open a new terminal, and

(in project directory) npm run android

will prompt the packager console (in another terminal) and build successfully
