У меня есть отчет об ошибке в консоли Google Play. Я не нашел ни одной строчки своего кода в этой трассировке стека - поэтому я не понимаю, что является источником этого вздора sh. Кто-нибудь может мне помочь?

Вчера, 6:56 утра в версии приложения 158 Samsung Galaxy A50 (a50), 3840 МБ ОЗУ, Android 10 Отчет 1 из 3

можете ли вы проверить свой код вот так? 

final ListView list = (ListView) findViewById(android.R.id.list);
final ListViewAutoScrollHelper scrollHelper = new ListViewAutoScrollHelper(list);
scrollHelper.setEnabled(true);
list.setOnTouchListener(scrollHelper);

и, пожалуйста, опубликуйте свой код, используя ListViewAutoScrollHelper код
