The term Android Linux tends to cause some confusion, or at least debate, within the tech world. Many ask, "Is Android really Linux?" It is, but maybe not completely. Linux is an operating system, like Windows 10 and Mac OS X 10.7 are operating systems, made up of a number of components, namely, the bootloader, kernel, daemons, shell, and graphical server. Android Linux is based on just one of these components: the kernel. Often, the kernel is what's referred to as Linux as a whole, since it's the core of the operating system, hence the confusion. So, yes, Android is Linux at its core, albeit perhaps a modified version of Linux.
What Is Android Linux?
It might be easier to consider the terms Android and Android Linux as one in the same. They refer to the operating system of many smartphones and other mobile devices (actually all devices that aren't made by Apple, which are based on the iOS operating system). Android is an open-source operating system; open-source meaning its source code can be modified to suit different devices and manufacturers. Android is developed by Google and used by a number of mobile device manufacturers including Sony, Samsung, and LG. Google updates versions of Android on a regular basis, but at its core remains the Linux kernel.
Who Uses Android Linux?
An Android Developer uses Android Linux to design and build advanced applications for mobile devices. Someone just entering the field, or a junior Android developer, usually also knows how to work with APIs and understands Android SDK, according to Treehouse. Java, SQL, and XML are essential skills too. Along with these technical skills, perseverance, willingness to collaborate, and a thirst for knowledge are personality traits that describe a successful Android developer. The salary range for an Android developer is $58,100 to $140,000, as calculated by LinkedIn.
