Unable to load script.Make sure you are either running a Metro server or that your bundle 'index.android.bundle' is packaged correctly for release

Answer 1

First of all make sure you have started the bundler using this command in root directory:

npm start 

or

react-native start

If doesn't work add assets folder manually in the following directory

android/app/src/main/{assets}

After that rename index.android.js to index.js then use the following command:

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

Now you can create your apk:

react-native run-android

Answer 2

"react-native": "0.64.1",

I've resolved this problem with changing bundleInDebug: true, in project.ext.react in android > app > build.gradle.

project.ext.react = [
bundleInDebug: true,
enableHermes: ***,  
]
