The bind value Fait apparemment référence à selectionArgs pour la sélection, que vous insérez dans query(). Si une telle valeur de selectionArgs est null, vous obtenez ceci.

@Gray et @pjv la réponse était le point pour réaliser quel problème a causé cette erreur. Vous devez être prudent avec la sélection et la correspondance selectionArgs, si vous passez selection = null et selectionArgs = something, vous obtiendrez également cette erreur! :) Merci!
