How to update badge in background?

[fabdrol]

Hey there,

Is there a way to update the badge icon when the app's in the background? The documentation is sparse, so it's difficult to tell..

Thanks!

Hello !

To update in background, it's not an issue about this module. You need to use Firebase Cloud Messaging, to allow your app to handle messaging notification. With that, your app will be able to run background task, and it allows you to update the badge there.

Add this line to index.js

AppRegistry.registerHeadlessTask("RNFirebaseBackgroundMessage", () => MyBackgroundService);

MyBackgroundService.js

export default async (message) => {
    console.log("Received!", message);
}

You need to set up your android manifest and link correctly the module.

For more info :

I let you mark as closed if you have no questions :)

Best regards,
Florient

@Linoa65 Will this work for iOS?

If you look at RN Firebases 6 documentation, Android highlights how it offers Foreground Service Notifications for dealing with long-running background tasks but nothing is said about iOS.

I can see why @fabdrol would say that the documentation is sparse because hard to tell one and two apart.

EDIT: I see that this is the react-native-android-badge repo, not the interface RN Firebase repo
