error: cannot access zzb class file for com.google.firebase.iid.zzb not found

Getting error:

error: cannot access zzb class file for com.google.firebase.iid.zzb not found

after including AccountKit:

    compile 'com.facebook.android:account-kit-sdk:4.+'

Also onCreate & onDestroy is not getting resolved.

    public class FirebaseInstanceIDService extends FirebaseInstanceIdService {

     @Override
      public void onCreate() {
        super.onCreate();
    }

      @Override
      public void onDestroy() {
        super.onDestroy();
    }
    }

Firebase & play services: v11.4.0

Firebase and play services libraries were older. Upgraded them to v15.0.0 and accountkit to v4.32 resolved compile errors and build errors.

• Update: 15.0.0 crashed at runtime when notification was received (fortunately app was in beta) Stacktrace: AbstractMethodError:firebase.iid.zzb.zzd(intent)

Solution- Downgrading them to 11.8.0 worked. (Accountkit v4.32)

• Update: Also faced problem of not receiving push notification on Oreo 8.0

Solution- Notification not showing in Oreo
