Kivy+Opencv camera not working on Android

[Vijay Raut]

Hello all, 

I am trying to use opencv, kivy and buildozer to build an app which uses camera on my android phone. Which works fine on Ubuntu/windows, 

But when I open the app on Android phone, the camera is not working. it shows a black screen with a small square in the left corner of the screen. 

Anyone can help me please?

I also tried plyer, pyjnius but nothing worked.

If you have any recommendations or another way to access Android camera , please let me know.

Thank you

The Kivy Camera doesn't work on Android, neither does the OpenCV camera. Use Xcamera from the Kivy Garden, it still has issues but is currently the best choice.
