what the fuck is this? i had to run the following command to make it work for a bare bone app for android.

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

hopefully i remember if i ever pull it from my git. this is fucking stupid. no docs whatsoever about the update to gradle 5 > above. all my dependencies don't work. my app just go kaput? plus stupid google play forces u to go to API28, anything less, they'll reply something like 'fuck off'.

did the job (was having the same error)

To resolve try the following:
1. Clear watchman watches: `watchman watch-del-all`.
2. Delete the `node_modules` folder: `rm -rf node_modules && npm install`.
3. Reset Metro Bundler cache: `rm -rf /tmp/metro-bundler-cache-*` or `npm start -- --reset-cache`.
4. Remove haste cache: `rm -rf /tmp/haste-map-react-native-packager-*`.

On Arch Linux, the files mentioned in step 3 and 4 may not exactly have the same name (e.g. metro-cache or haste-map-metro). To make sure you delete the temp files, navigate to /tmp directory and delete anything with metro or haste in it, yourself.

In my case, the emulator was on airplane mode.
Make sure your emulator or mobile phone can communicate with the Metro server.

I m facing again this issue when I upgraded to react native 0.62.0
Any idea how to resolve it ?

Pessoal, essa solução funcionou para mim:

Não foi possível carregar o script dos ativos 'index.android.bundle'. Certifique-se de que ...
Esse erro geralmente ocorre porque o sistema não conseguiu criar o pacote inicial que contém todo o código Javascript da aplicação.

1- Para resolver, comece a criar uma pasta de ativos dentro da pasta android / app / src / main.

2- Logo após, execute o comando:

npx react-native bundle --plataforma android --dev false --entry-file index.js - android-app de saída de pacotes / app / src / main / assets / index.android.bundle --assets-dest android / app / src / main / res /

3- Agora, feche o terminal e execute novamente o comando:

npx react-nativo run-android
ou fio executar react -nativo run-android
ou fio android

And even this won't work if you manually do not create the assets subfolder in the android/app/src/main folder. Thanks for the command!
