Question

下午好，有一个使用python，kivy和opencv编写的小应用程序。 buildozer的构建没有错误，但是当我在手机上启动应用程序时，它崩溃并显示以下错误：

04-12 18：44：54.848 5697 5739 I python：文件   “ /home/max/desktop/finish/.buildozer/android/app/main.py”，模块第13行

04-12 18：44：54.848 5697 5739我python：   ModuleNotFoundError：没有名为“ cv2”的模块

已安装Opencv，我使用PyCharm编写代码。可能是什么问题？

需求= python3，kivy，numpy，opencv

Project_1App().run()

APK中没有cv2模块
