[chrisvidal]

check your code that handles the event setNotificationWillShowInForegroundHandler

in the code that I copied/pasted from the website, there was this line that is blocking the badge. just comment it.

event.complete(null);

Hello @ayyuby26,

To resolve this issue on Android, you can create an Android Notification Channel where you can define the importance of notifications. By defining a high priority, you will receive sound and popup notifications as well. If you are using an API, you need to define that channel ID in Notification API as key ‘android_channel_id’ and value as ‘your_android_channel_id’, which you can obtain from your OneSignal Dashboard by going to Settings > Messaging > Android Notification Channels.

I hope this will solve your issue.
