Android Question Crashlytics Error

After some SDK update from B4a SDK Manager, now my application that integrate Firebase Crashlytics goes in crash at the moment of start.
From Unfiltered log i've seen this error


java.lang.NoSuchMethodError: No virtual method isDataCollectionDefaultEnabled(Landroid/content/ContextZ in class Lio/fabric/sdk/android/services/common/FirebaseInfo; or its super classes (declaration of 'io.fabric.sdk.android.services.common.FirebaseInfo' appears in /data/app/in.raguso.educom-2/base.apk)
