我正在用buildozer运行此代码，但是每次我在Android设备上单击拍照时，应用程序就会崩溃。主屏幕出现文件，构建正常。我添加了额外的权限，并提出了对python 2的要求。我也已将android添加到要求中，但仍然无法正常工作。

# You can define all the "list" as [section:key].

# 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
