Kivy Buildozer AttributeError:“Context”对象没有属性“hostpython”

Question

我正在尝试使用buildozer为一个简单的python3/kivy应用程序构建一个apk，在我直接从虚拟机中获得的kivy.org网站，这是第二天，仍然没有运气。我有很多错误，不稳定的pip，更新的buildozer，pip安装的morse，pnglab，sh，appdirs，setuptools for py3，但现在我遇到了这个错误，我必须承认它真的让我抓狂了，有人知道这是怎么回事吗？我很想得到一个答案，因为我计划有一天把机器人开发作为我的工作，谢谢。这是错误：
AttributeError:“Context”对象没有属性“hostpython”

以及回溯：

Answer 1

这是由于新的pythonforandroid工具链中的一个bug引起的（这个bug是android_newbuildozer目标使用的）。您可以通过将python版本目标添加到需求中来解决这个问题，例如requirements = kivy,python2。在

Answer 2

基弗1.9 如果在buildozer.spec文件

要求=kivy，python2

对于Python3 要求=kivy，python3

Answer 3

实际上，对于Python3，要求是

requirements = kivy,python3crystax

你需要crytaxndk（https://www.crystax.net/en/android/ndk）而不是android NDK
