Android is a mobile operating system developed by Google. It is based on a modified version of the Linux kernel and other open source software, and is designed primarily for touchscreen mobile devices such as smartphones and tablets. In addition, Google has further developed Android TV for televisions, Android Auto for cars, and Wear OS for wrist watches, each with a specialized user interface. Variants of Android are also used on game consoles, digital cameras, PCs and other electronics. Initially developed by Android Inc., which Google bought in 2005, Android was unveiled in 2007, with the first commercial Android device launched in September 2008. The operating system has since gone through multiple major releases, with the current version being 9 "Pie", released in August 2018. The core Android source code is known as Android Open Source Project (AOSP), and is primarily licensed under License.
Memory management:
Since
Android devices are usually battery-powered, Android is designed to manage
processes to keep power consumption at a minimum. When an application is not in
use the system suspends its so that,
while available for immediate use rather than closed, it does not use battery
power or CPU resources.Android manages the applications stored in memory
automatically: when memory is low, the system will begin invisibly and
automatically closing inactive processes, starting with those that have been
inactive for the longest amount of time.Lifehacker reported in 2011 that
third-party task killer applications were doing more harm than good. Android's kernel is
based on the Linux kernel's long-term support (LTS) branches. As of 2018,
Android targets versions 4.4, 4.9 or 4.14 of the Linux kernel.The actual kernel
depends on the individual device.
