Android does not support badges, is there a workaround for this?
By design, Google chose not to include badges in Android. A way around this limitation is to use status bar icons, and to use custom logic in your app to update the status bar icon using silent notifications. For more information, please refer to Notification Styling (https://docs.carnival.io/docs/android-integration#section-notification-styling) and Silent Push Notifications for Android (https://docs.carnival.io/v1.0/docs/silent-push-notifications).
In general, we suggest to engage users with push notifications content that stands out, such as rich notifications and emojis, and to drive users to your app by devising a messaging strategy that can keep your users engaged.
