React Native app shows 'index.android.bundle' error when setting targetSdkVersion to 28

See original GitHub issue

🐛 Bug Report

After I updated my targetSdkVersion from 27 to 28, I ran react-native run-android connected to an emulator and was presented with a screen stating “Unable to load script from assets ‘index.android.bundle’. Make sure your bundle packaged correctly or you’re running a package server.”

To Reproduce

From a new or existing (functioning) React Native app, change the targetSdkVersion in android/build.gradle file to 28.

Expected Behavior

The app loads as it did before.

Starting with Android 9.0 (API level 28), cleartext support is disabled by default.

AndroidManifest.xml file change as following

<?xml version="1.0" encoding="utf-8"?>
<manifest ...>
    <uses-permission android:name="android.permission.INTERNET" />
    <application
        ...
        android:usesCleartextTraffic="true"
        ...>
        ...
    </application>
</manifest>
