Я только что создал приложение для Android, используя Kivy и Buildozer. У меня не было ошибок при создании APK, поэтому я установил его на свое устройство Android. Каждый раз, когда я открывал приложение, оно сразу вылетало. Я провел небольшое исследование и использовал команду «buildozer debug deploy run logcat», чтобы увидеть ошибку.

Ошибка Logcat: <код> 10-26 15: 07: 36.844 30880 14455 I python: Android kivy bootstrap завершен. __name__ это __main__ 10-26 15: 07: 36.844 30880 14455 I python: AND: Выполнить строку 10-26 15: 07: 36.844 30880 14455 I python: запустить пользовательскую программу, сменить каталог и выполнить точку входа 10-26 15: 07: 36.844 30880 14455 I python: точка входа не найдена (.py), прерывание.

Я понял, что мой файл python был назван Main.py, поэтому я изменил его на main.py, потому что понял, что это должно быть именно так.

Когда я это сделал, я получил еще одну ошибку <код> ОШИБКА СБОРКИ: в каталоге вашего приложения не найден файл Main.py (o). Этот файл должен существовать, чтобы действовать как точка входа для вашего приложения. Если ваше приложение запущенный файлом с другим именем, переименуйте его в Main.py или добавьте Main.py, который его загружает.

Любая помощь была бы замечательной !!!

#[app]
#source.exclude_patterns = license,data/audio/*.wav,data/images/original/*

#   Profiles
#
#   You can extend section / key with a profile

#   and extend the excluded directories to remove the HD content.
#
#[app@demo]
#title = My Application (demo)
#
#[app:source.exclude_patterns@demo]
#images/hd/*
#
#   Then, invoke the command line with the "demo" profile:
#
#buildozer --profile demo android debug

В ответ на вопрос об ошибке ... есть ли в вашем приложении файл с именем main.py?

Когда я помещаю свое имя файла в "main.py", я получаю сообщение об ошибке BUILD FAILURE: No Main.py(o) found in your app directory. This file must exist to act as the entry point for you app. If your app is started by a file with a different name, rename it to Main.py or add a Main.py that loads it.

Возможно, потребуется сделать buildozer android clean.

Просто попробовал очистить buildozer android и получил это /home/a/PycharmProjects/Knix-Safe/.buildozer/android/platform/python-for-android/pythonforandroid/toolchain.py:85: DeprecationWarning: the imp module is deprecated in favour of importlib; see the module's documentation for alternative uses import imp

Это просто предупреждение. Теперь создайте свое приложение обычным способом и посмотрите, что произойдет.

2 ответа

Вам нужен файл main.py для компиляции с помощью buildozer. Например, у меня есть

index.py

А также

content.py

И я попробую скомпилировать

buildozer init
buildozer -v android debug

У меня должна быть ошибка, потому что у меня нет main.py. Итак, просто переименуйте свои файлы и не забудьте также переименовать файлы kivy.

Кроме того, вашему main.py нужна точка входа, например

if __name__ == '__main__':
    ConnectApp().run()

взгляните на свой файл buildozer.spec, он будет искать main.py в вашем текущем каталоге, ваш main.py должен находиться в том же каталоге, что и ваш файл buildozer.spec (каталог, из которого вы запускаете команду buildozer)

    #(str) Source code where the main.py live
    source.dir = .
