I have updated React Native to 0.60-RC2, migrated to AndroidX using the Android Studio refractor and used the jetifier mentioned here: https://github.com/react-native-community/
Add below in your app/build.gradle
// On top of the file
def useIntlJsc = false
//inside dependencies
if (useIntlJsc) { implementation 'org.webkit:android-jsc-intl:+' } else { implementation 'org.webkit:android-jsc:+' }
