Android device file

[LuckyLuke8]

For Android, what is the way to use hardware device? I mean to interact with hardware I need to get /dev/* file or it is not necessary and an application can use hardware without the existence of the device file?

Sorry. I can provide more details. I’m interested to monitor all resources related to video recording through camera in Pixel 3a with Android 8.0. So to do that, I’m used the Android camera application to record a merely a video. I discovered that although the camera works, there is not any device file in /dev. It is strange. I know that Android handles device as Linux so i should find a device file in /dev that binds driver device(major number) to hardware device (minor number )…

Sorry Lucky I don't know much about phones hardware, I know the basics and find programs to use the internal hardware, if i need too.
My main computer is running Ubuntu and I have installed many different versions of Linux on my computers laptops over the years but none of this will help with your question.

Hmmm... so there is no /dev file that is connected with the camera's file explorer?
