Fatal Exception: java.lang.NoSuchMethodError: No static method (Ljava/lang/String;)V in class Lcom/adform/adformtrackingsdk/a; or its super classes (declaration of 'com.adform.adformtrackingsdk.a' appears in base.apk)

Android version: Android 8 API 26
SDK versione: 2.5.5 (com.adform.tracking.sdk:adform-tracking-sdk:2.5.5)

I get this error inside onCreate of my first activity, when I setup AdFormTracking

AdformTrackingSdk.setAppName("DemoAndroid");
trackPoint = new TrackPoint(TRACKING_ID);
AdformTrackingSdk.startTracking(this, TRACKING_ID);
AdformTrackingSdk.setFacebookAttributionIdTrackingEnabled(false);

Excepition generate from the first line "setAppName".

With previous version this error not happened
