我在 debian 上使用 buildozer 制作 apk 时遇到了一些问题：当我在 debian 上启动我的应用程序时它可以工作，但是当我在我的 android 手机上启动它时，我得到了这个：

欢迎 Stack Overflow。您是否在计算机上安装了 Cython？根据错误消息，07-25 19:56:59.385 14073 14190 I python : [ERROR ] [Clock ] Unable to import kivy._clock. Have you perhaps forgotten to compile kivy? Kivy contains Cython code which needs to be compiled. A missing kivy._clock often indicates the Cython code has not been compiled. Please follow the installation instructions and make sure to compile Kivy .
@ikolim，电脑上一切正常，Cython 已安装。
这与库有关。我建议您 (a) 检查 buildozer 文件中的要求，以确保您是否已添加您在应用程序中使用的所有内容，并且 (b) 如果没问题，您可能正在使用具有 C 绑定的库和在 Android 上不容易兼容，例如，如果您使用 matplotlib 或 scikit-learn 之类的库，它很可能无法在 Android 上运行。
@DipanshuJuneja，我用的是 paho-mqtt
