我正在学习kivy并且在一个简单的标签应用程序中成功使用buildozer之后，我制作了一个使用按钮稍微复杂一点的kivy应用程序，奇怪的是这个kivy应用程序在我的计算机上完美运行并且与kivy启动器，但当我使用buildozer创建和apk并将其安装在我的手机中时，该应用程序并没有做任何事情;当我启动应用程序时，加载屏幕显示带有kivy徽标，之后是黑屏，没有任何内容。我没有从kivy导入任何库，为了测试我做了一个非常简单的1按钮kivy应用程序，同样的事情发生。
- 我只在main.py中导入kivy，因此我不认为在buildozer中导入的库中添加任何东西都与问题有关。
- 日志不会显示任何内容，来自使用乒乓游戏的应用程序的日志和带有不起作用的按钮的应用程序完全相同。
- 应用程序没有崩溃只是留在黑屏，所以我认为在apk中没有正常运行，但它可以在我的电脑和手机中的kivy启动器中工作，这就是为什么我相信可能是使用buildozer创建应用程序时的某些配置会使应用程序在手机中表现得很奇怪。
- 与其他有效的应用程序的唯一区别是按钮，也许某些东西会因为按钮而导致应用程序无法正常工作？但是更奇怪的是，动画等更复杂的东西会起作用但按钮不会。 如果有人有任何想法我会很感激帮助。

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

# This can be translated into:
#
#[app:source.exclude_patterns]
#license

# -----------------------------------------------------------------------------
# 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
