Which kernel operating system is used in Android?

Linux kernel
Android uses the Linux kernel under the hood. Because Linux is open-source, Google’s Android developers could modify the Linux kernel to fit their needs. Linux gives the Android developers a pre-built, already maintained operating system kernel to start with so they don’t have to write their own kernel.

What is kernel level programming?

The kernel is a computer program at the core of a computer’s operating system and has complete control over everything in the system. The kernel’s interface is a low-level abstraction layer. When a process requests a service from the kernel, it must invoke a system call, usually through a wrapper function.

Do device drivers run in kernel mode?

A software driver is not associated with a hardware device. Also, software drivers() always run in kernel mode.
