【问题描述】：
我正在尝试在我的其他问题上取得一些进展 --> Kivy Launcher - AttributeError: ‘MyInputs’ object has no attribute ‘get_focus_next’
我现在的意图是构建 Kivy Launcher（欢迎提出关于如何制作 android python 应用程序原型的替代建议，但无论如何我仍然想完成这个）。但是，我遇到了新的障碍。 Python-for-android 在构建过程中一直失败，具体如下所示。
构建命令：
p4a apk --requirements=python2,kivy --permission WRITE_EXTERNAL_STORAGE --name="R Kivy Launcher" --package=com.kivy.rkivylauncher --version=0.0.1 --android_api 28 --bootstrap=pygame --launcher --minsdk 13
错误内容（下面是我认为可能很重要的系统和配置内容）：

系统： Cygwin 3.0.3
配置： - Python 3.7 -python-for-android 0.7.1 - 建造者 0.39 - sdk-tools-linux-4333796.zip - android-ndk-r19b-linux-x86_64.zip (是 有 AMD 特定的变体吗？到目前为止，谷歌拒绝...）
很高兴分享更多信息，只是不确定还有什么重要/可能相关。我有一些完全疯狂的怀疑（Cygwin 和线程/锁不兼容？），但这就是我所得到的。
帮助？

在上面回答我自己的问题（有点）：虽然我现在知道有很多设置要求可以允许直接使用 p4a，但最后我总体上想出了以下内容：
