抱歉可能存在愚蠢的问题，但今天我花了大约5个小时尝试使用Python3，Buildozer和Crystax NDK构建简单的apk。我使用了Buildozer VM，下载了Crystax ndk 10.3.2，在github指令https://github.com/kivy/buildozer上创建了buildozer.spec。我的buildozer.spec：
title = Cyba app
package.name = cyapp
package.domain = ru.longint
source.dir = .
requirements = python3crystax,kivy
android.ndk_path = ~/.buildozer/crystax-ndk
和其他几个人。
当我运行buildozer -v android debug进行第一次编译时（通过Buildozer＆＃39; s wiki上的指令），我得到了下一个日志：

以下是我的问题： 1）字面意思是什么是python3crystax？是pip包，实用程序，文件还是什么？ 2）我必须手动下载python3crystax，我可以在哪里下载这个？ 3）我做错了什么？
UPD：
我找到了this个问题并尝试了buildozer -v android_new debug
得到这个（buildozer.spec中的log_level是2）：

我在日志中看到一些奇怪的字符串。我在Crystax ndk文件夹中真的没有这条路。

答案 0 :(得分：0)
确保buildozer.spec文件中包含以下行：
requirements = python3crystax，kivy
android.ndk_path = /opt/crystax-ndk-10.3.2
