Buildozer无法执行将kivy转换为apk的最后一个命令

Question

我正在尝试将测试python kivy文件转换为apk。我想避免下载virtualbox和在虚拟机上运行linux等冗长的方法，所以我决定在pythoneverywhere.com上使用bash控制台。我仔细地遵循了https://kivy.org/doc/stable/guide/packaging-android.html的说明，但最后一个命令buildozer android debug deploy run不起作用，输出如下：

11:13 ~/buildozer (master)$ buildozer android debug deploy run

它说它无法解压缩此文件–android-ndk-r19b-linux-x86_64.zip但是，如果我打开该文件，它似乎不是zip文件，而是html：

Answer 1

这是由于下载url不再可用而导致的错误。它应该在p4a主程序中修复，除非您更改它，否则buildozer应该将其拉到这里

要暂时解决此问题，请尝试将buildozer.spec中的NDK版本条目更改为19c

Answer 2

首先尝试将其转换为apk

buildozer -v android debug
