Nie potrafię tego rozgryźć, walczę z tym od wielu dni i jestem tym zmęczony ...

Zmieniam rozmiar tekstu TextView na AppWidget za pomocą Spinnera z działania konfiguracyjnego i nie mogę go poprawnie zaktualizować. Nie aktualizuje się za pierwszym razem, kiedy mu to mówię, ale aktualizuje drugą i trzecią i za każdym razem.

Naprawdę naprawdę doceniam, jeśli ktoś przyjrzy się mojemu kodowi

Dziękuję Ci bardzo
