不能用buildozer和python3crystax构建Kivy项目

Question

对于可能的愚蠢问题，我很抱歉，但今天我花了5个小时试图用Python3、Buildozer和Crystax构建简单的apk。我使用Buildozer VM，下载了Crystax ANDK10.3.2，在github指令https://github.com/kivy/buildozer上创建了https://github.com/kivy/buildozer。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

其他人也不多。当我运行buildozer -v android debug来进行第一次编译(通过Buildozer的wiki上的指令)时，我得到了下一个日志：

下面是我的问题:1) python3crystax到底是什么？pip包、实用程序、文件还是什么？(2)我必须手动下载python3crystax，在哪里可以下载这个?3)我做错了什么？

UPD:我发现了这的问题，并尝试了buildozer -v android_new debug (log_level in buildozer.spec 2)：

我在原木上看到一些奇怪的字符串。我真的没有这个路径在晶体ndk文件夹。

[WARNING]: include directory doesn't exist: /home/kivy/.buildozer/crystax-ndk/sysroot/usr/include/arm-linux-androideabi

Answer 1

1. 下载并解压结晶NDK，例如/opt/
2. 确保您的buildozer.spec文件中有以下行。 需要python3crystax： requirements = python3crystax，kivy 指向提取晶体-ndk的目录： android.ndk_path =/opt/晶体-NDK-10.3.2
