Вылетает Android Kivy Launcher

Question

Я новичок в Python и все еще учусь, я пытаюсь запустить код на Android Kivy Launcher, но он каждый раз вылетает. Запуск его на компьютере не показывает никаких ошибок, он работает правильно. Я изменял его много раз, я импортировал файл kivy (Builder.load_file вместо Builder.load_string), и проблема все еще возникает.

Заранее спасибо
