Kivymd APK 应用程序(使用 Buildozer 创建)在打开后关闭

Kivymd APK App (created with Buildozer) closes after opening up

我使用 Buildozer 从 Python Kivy & KivyMD 创建了一个 APK 文件。当我安装后打开该应用程序时,它会显示初始图像,然后关闭。 我已经检查并发现它们在 main.py 中似乎没有问题,因为我在 Buildozer.spec 文件的要求中正确列出了 Kivy 和 KivyMD。 (kivy==2.0.0,kivymd==0.104.1)

这是我的代码..

#    List as sections
#
#    You can define all the "list" as [section:key].
#    Each line will be considered as a option to the list.
#    Let's take [app] / source.exclude_patterns.
#    Instead of doing:
#
#[app]
#source.exclude_patterns = license,data/audio/*.wav,data/images/original/*
#
#    This can be translated into:
#
#[app:source.exclude_patterns]
#license
#data/audio/*.wav
#data/images/original/*
#


#    -----------------------------------------------------------------------------
#    Profiles
#
#    You can extend section / key with a profile
#    For example, you want to deploy a demo version of your application without
#    HD content. You could first change the title to add "(demo)" in the name
#    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

根据我的说法,问题出现在 model.py 文件中,我已经导入了 Keras、NLTK 等模块,但我没有在要求中提及它们。 如果这是问题所在,请根据我的 model.py 和其他人给出我应该在要求中写的完整声明 请指导我。

如果您有其他一些插件,只需像这样添加它们:

# comma separated e.g. requirements = sqlite3,kivy
