Android получает исключение нулевого указателя в java.util.Objects.requireNonNull (Objects.java:203)

Question

Я читаю написание строковых массивов и отображаю их в виде переработчика.Перед их отображением я меняю порядок, используя Collections.reverse (Arrays.asList (FilePathStrings));Вот исключение, которое я получаю:

Answer 1

Arrays.asList(null) выдает это исключение.Ваш параметр (FilePathStrings) равен нулю.
