I tried to build and android apk file using buildozer and VM (Ubuntu 20.04 64-bit). Apk file was built without problems, but when I tried to install the app on android and run it, "adb logcat" command showed me the following error:
dlopen failed: "/data/data/org.test.solvescan/files/app/_python_bundle/site-packages/cv2/cv2.so" is 64-bit instead of 32-bit
By the way, I tried to build apk file on the same VM but without using cv2 library and it worked without any error.
