How to fix error when launching buildozer app on android?

Question

Android

After launching the application apk built with buildozer and the kivy library, it immediately crashes.
1) the application uses a camera and after adding it, the application stopped working on phones (it worked before)
2) specified android.permissions=CAMERA in buildozer.spec, but the phone did not request access to the camera. What could be the problem? And on the phone, I gave access to the camera to my application, but it also crashes.
