У меня проблема, я получаю данные из базы данных и мне нужно сохранить данные в sharedpreferences, но при этом выдается следующая ошибка: java.util.HashMap не может быть приведен к java.util.Collection
Код для моего запроса:
val training2 = mutableMapOf<WeekDay, ArrayList<ArrayList<ExerciseModel>>>()
val train = data["training2"] as MutableMap<*, *>
with(train[WeekDay.SUNDAY.name] as? ArrayList<ArrayList<ExerciseModel>>){
this?.let {
training2[WeekDay.SUNDAY] = it
}
}
with(train[WeekDay.MONDAY.name] as? ArrayList<ArrayList<ExerciseModel>>){
this?.let {
training2[WeekDay.MONDAY] = it
}
}
, и если я пытаюсь сохранить на sharedPreferences его сбой, мое приложение
fun putUser(context: Context, user: User) {
val sharedPreferences = getSharedPreferences(context)
sharedPreferences.edit().putString("user", Gson().toJson(user)).apply()
}
