Gradle Build échouant avec Java.lang.IllegalStateException: BEGIN_ARRAY attendu mais STRING au chemin de la ligne 1 de la colonne 1 $

Je crée une application qui récupère les données de Firebase, les ajoute dans un adaptateur de tableau et les affiche dans une vue de liste. Lorsque j'essaie de créer l'application, elle échoue avec:

Erreur: l'exécution a échoué pour la tâche ': app: transformClassesWithInstantRunForDebug'. Java.lang.IllegalStateException: BEGIN_ARRAY attendu mais STRING au chemin de la ligne 1 de la colonne 1 $

Oui, c'est juste un bug dans Android Studio, essayez Build -> Clean Project, puis cliquez sur Build -> Rebuild Project
