java.lang.IllegalAccessError classe ref dans preverified classe résolu à l'inattendu de la mise en œuvre

Im obtenir une "java.lang.IllegalAccessError classe ref dans preverified classe résolu à l'inattendu de la mise en œuvre" d'erreur lorsque que j'appuie sur un bouton qui lance une méthode dans MainActivity qui est censé commencer une nouvelle Activité. Que puis-je faire pour résoudre ce problème? Ceci est ma première tentative de faire une application android, donc jaurai besoin des instructions étape par étape 🙂

Aussi que je n'ai pas pu tester si elle fonctionne encore, mais si vous remarquez quelque chose de mal avec mon AugiActivity service de la mise en œuvre ou la diffusion locale de la mise en œuvre hésitez pas à me le faire savoir.

Merci!

fyi: MainActivity commence la Navigation de l'Activité, qui démarre Service AugiActivity

Augi activité envoie locale la diffusion de messages à la Navigation
