首先，我要感谢您抽出宝贵时间提供帮助！请注意，由于长度容量，缩短了kv文件。
无论如何，我试图使用kivy / python打包apk。该应用程序在我的Macbook，Linux VM和我的Android设备（三星Galaxy S6 Edge）上的KivyLauncher上运行良好。这时，我使用的唯一模块是基于kivy，或sqlite3（我在buildozer.spec中指定）。我正在使用buildozer和cython v0.20编译apk。下面是我的main.py，kv文件，buildozer.spec和logcat。
这是我的main.py：

#

# 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
