But what's your issue? The plugin only returns correct badge number if it was set through the plugin itself (on Android because Android has to API for it).

Onesignal push notification increase the badge notification by one, which is visible on app icon.
But when I try to get badge notification on Android with Badge.get()it returns 0

I have the same issue, I'm using OneSignal and Badge for Ionic 3. Badge.get() always returns 0.
