Вылет приложения Kivy после загрузки ⇐ Android

[Anonymous]

Я студент бакалавра инженерных наук и все еще учусь на втором курсе, но пытаюсь разработать базовое приложение-помощник, используя Python и Kivy (которое я пытался изучить самостоятельно).У меня есть код, написанный для приложения, который отлично работает в моей системе Windows, но для упаковки исходного кода в APK я использовал учетную запись Google Collab и установил среду Ubuntu и buildozer. APK также создается успешно, но при установке на любое устройство Android приложение вылетает сразу после отображения «(Kivy Logo)Loading...»
Я пробовал менять части кода, а также содержимое файла спецификации, но ничего не помогло.
Я новичок в Kivy и разработке приложений, поэтому (честно говоря) мало что знаю о logcat и отладке apk.
Я бы буду очень благодарен, если кто-нибудь сможет мне с этим помочь.
Это мой код:
