Android emulator is working when running the application but on a real device the app gets an error from the action bar. I am using android bumble bee and the device is a Samsung s21
I already have NoActionBar as well as windowNoTitle true and windowActionBar false
Here is my error
Process: com.example.wonderfinder, PID: 14427

I'm going to take a wild stab in the dark here and assume that you are using dark mode (night mode) on your device, but normal (day mode) on the emulator. Am I right??
