В моем приложении у меня есть вкладки и связанные с ним фрагменты. Мое приложение отлично работает в режиме potrait, но когда я меняю ориентацию на альбомный режим, приложение становится краш.Фрагменты сбой в ландшафтном режиме
Что я должен делать, чтобы мое приложение работало нормально в обеих ориентациях.
Это моя основная деятельность:
