推薦答案
kivy啟動器用于嚴格運行Kivy模塊和Python預裝模塊.所以在這種情況下，由于 cv2 沒有預裝在正常的 python 安裝中，kivy 啟動器無法識別它，然后得到一個ModuleNotFoundError: No Module named cv2"錯誤，這會導致它崩潰.因此，如果您嘗試導入預裝 python 的模塊以外的模塊，則必須使用 Buildozer 編譯成 .apk 文件才能在 android 上運行它
The kivy launcher is used to run strictly Kivy modules and Python preinstalled modules. So in this case, since cv2 doesn't come preinstalled in normal python installations, kivy launcher doesn't recognise it and then gets a "ModuleNotFoundError: No Module named cv2" error, which causes it to crash. So, if you're trying to import modules aside from those which come preinstalled with python you'd have to compile into a .apk file using Buildozer to run it on an android
