将 kivy 应用程序转换为 apk 的问题（确认 SSL 证书的问题）

Question

嗨，我正在尝试将我最近刚刚构建的 Kivy 应用程序转换为 android APK 文件，但是我遇到了下面的错误，有人可以解释一下问题是什么，并帮助我解决它一直在尝试几个小时查看多个视频似乎无法修理它。 我不确定这是否与 Cython 有关，因为我已经使用 pip 安装了 cython，但它仍然给我这个错误。

Answer 1

堆栈跟踪中的这个特定部分是错误（第一行）

There was a problem confirming the ssl certificate

当缺少 buildozer 依赖libssl-dev时会发生这种情况。

运行以下命令

sudo apt-get update
sudo apt-get install libssl-dev
buildozer android clean

然后做

buildozer android debug deploy run

这应该可以解决问题。
