Ошибка Android Presenter для Android TV: не устанавливайте LayoutFrozen в макете или прокрутке

Question

Я пытался создать собственный докладчик, используя только один пользовательский вид, который воспроизводит видео в виде поверхности, и после первой привязки я получаю это сообщение об ошибке. В чем проблема? Я не устанавливаю логическое значение для замораживания слоя или чего-то подобного.

Весь проект можно найти здесь

Answer 1

Реализация презентатора выглядит хорошо. Кажется, что вы запускаете прокрутку или макет во время входного перехода.

Правильно ли вы создали подкласс BrowseFragment? Можете ли вы поделиться своим кодом приложения?
