我是Kivy的新手，正在使用buildozer。然而，我已经按照buildozer.readthedocs中的说明运行了"；buildozer-v android调试部署运行logcat>my_log.txt"；尽我所能，然而，apk在显示预弹出屏幕后立即崩溃。在检查my_log.txt时；追溯&"；。
我在谷歌上搜索了任何线索来解决我面临的问题，但都无济于事。任何关于变通办法的建议都将不胜感激。

#[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
我认为问题出在kivy版本中。kivy 2.0.0有一个错误。所以最好的版本是kivy 2.0.0rc4。你应该通过设置下载插件。在您的buildozer.specrequirements中，您应该指定kivy的版本，如下所示：
# comma separated e.g. requirements = sqlite3,kivy
requirements = python3,kivy==2.0.0rc4
在我看来，一个或多个依赖库存在问题。Kivy不能很好地处理Android上的所有依赖软件包，即使你在需求中列出了它们。
有些Python包可能需要菜谱。以下是迄今为止开发的食谱列表：https://github.com/kivy/python-for-android/tree/master/pythonforandroid/recipes
在你的情况下，你应该得到答案运行你的应用程序与logcat。建筑商规范中的未付款后续线路
android.logcat_filters = *:S python:D
然后通过ADB构建、部署和运行：
buildozer -v android debug deploy run logcat
顺便说一句。如果您看到消息"；无法提取私人数据"；在启动屏幕上，可能是因为Pygments的要求。尝试将其从需求列表中删除。
