Intl.numberformat in React native works fine when running in ios but not in android

Question

I am developing an app with React Native to run on IOS and Android. I use Intl.numberformat() to print currency, and it works smoothly when the app runs on IOS, but I get this error when running on Android: ReferenceError: Can't find variable: Intl.

How can I make it run in both plataforms?

Answer 1

I had faced similar issue. The issue was with Javascript core which runs the react- native. There are two ways to overcome this.

1.Method 1 You'll have to integrate latest javascript core into your android build or upgrade react native to 0.59

You can find it here

2. Method 2 Add or override the following code in your app/build.gradle

def jscFlavor = 'org.webkit:android-jsc-intl:+'

Clean build and react-native run android

Only method 2 worked for me. Using RN 0.66 – Hermitage

How could we fix this if the app is using Expo? – Insider

@EstebanChornet Did you find any solution for Expo? – Alula

Installing the intl package solved the issue for me for expo building on android npmjs.com/package/intl – Insider

I installed [email protected] with [email protected] and it doesn't work for me for some regions like pt-BR on Android. NumberFormat returns a number in the imperial format while it should be metric. On iOS it works though. – Thirsty

My problem was that the library Intl wasn't formatting my numbers correctly for specific regions, All I had to do was to import every locale considered in the beginning of the file like: import "intl/locale-data/jsonp/pt-BR" and it worked. With extra steps you can import it dynamically, which then I did, probably better. – Thirsty

@EstebanChornet you should place your comment as a full answer to the question. – Algeria
