Я создаю приложение для Android, используя kivy и buildozer.Приложение вылетает при запуске, и я обнаружил эту ошибку типа.Таким образом, я получаю журналы, используя logcat и эту ошибку после нескольких строк из traceback.Я использую Kivy 1.9.0 и Python 2.7.9 Есть ли способ это исправить?Пожалуйста, скажите мне, как это исправить.Спасибо.T_T
