You should request camera permission on API >= 23 https://github.com/yuriy-budiyev/lib-demo-app/blob/master/app/src/main/java/com/budiyev/android/libdemoapp/codescanner/CodeScannerActivity.java
@yuriy-budiyev
Facing the same issue on some devices.
Android manifest has permission for Camera and there is run-time permission modal implemented in the Activity as well. Library works flawlessly in devices API >23.
Still found the same error.

@yuriy-budiyev yes. Permission is added in manifest as well as runtime permission is also asked. Therefor Library is working in majority of devices in the developed App. I have found some devices mentioned earlier which don't support this library (Original Comment). I would recommend implementation of Camera2 API compatibility. My project is set to minSdkVersion = 19. Although CameraX is introduced in Android Jetpack, it requires minSdkVersion = 23, which will not benefit to this library.
I will update to Camera2 API when devices lower than 21 SDK become irrelevant
facing this issue. is there any update?
below Is the stack trace

Check camera permissions and update to 2.1.2 for better error handling.
